As the flow rate, pressure and composition of a working fluid may directly or indirectly influence the quality and production rate of products. Accordingly, in order to makes sure that the working fluid is used under a constant pressure, some technologies related to pressure control, flow rate control or fluid composition analysis may be applied to industrial manufacturing processes or machines to effectively control the working fluid.
For the purpose of effectively enhancing the efficiency, safety, production rate, quality and satisfying environmental-protection requirements, the target gas composition usually needs to be analyzed by a gas analyzer. In this way, the technician can understand the environmental condition of the target, and provide the solutions or improving methods accordingly to solve the above problems.
However, the gas is usually analyzed under normal temperature and pressure. In addition, back pressure may be generated at the moment of the gas being outputted from the gas analyzer; for the reason, the gas may not be effectively outputted from the gas analyzer, which may influence the analysis result. Currently, the technician usually inputs a driving gas (e.g. an inert gas) to assist the gas analyzer so as effectively exhausting the tail gas.
However, the currently available technologies cannot effectively control the flow rate or pressure of the tail gas. Moreover, the currently available technologies cannot effectively distribute the driving gas when the driving gas used to assisting in exhausting the tail gas, which may result in the waste of the driving gas or insufficiency of the driving gas. Therefore, it has become an important issue to provide a control system capable of controlling the flow rate and pressure of the tail gas, and effectively distributing the driving gas to save the driving gas in order to solve the disadvantage of prior art.

For a better understanding of the aforementioned embodiments of the invention as well as additional embodiments thereof, reference should be made to the Description of Embodiments below, in conjunction with the following drawings in which like reference numerals refer to corresponding parts throughout the figures.
The following description is about embodiments of the present invention; however it is not intended to limit the scope of the present invention.
Please refer to
In addition, the tail gas exhausting pressure stabilization control system of the present invention is provided with a tail gas inlet 13, a driving gas supplying end 14, a safety outlet 15 and a tail gas exhausting outlet 16 in order to connect the above components with each other. More specifically, the tail gas inlet 13 is configured to receive a gas. The driving gas supplying end 14 is configured to receive a driving gas. The safety outlet 15 is configured to exhaust the gas or the driving gas when the pressure thereof is excessively high. The tail gas exhausting outlet 16 is configured to output the gas and the driving gas or output the mixed gas of the gas and the driving gas.
Since the present invention has two flow paths for the gas and the driving gas respectively. The following will describe the two flow paths respectively.
The gas distribution tube 11 is connected to the tail gas inlet 13 to receive the gas.
The flow stabilizer 20 is connected to the gas distribution tube 11 to receive the gas. The flow stabilizer 20 mainly uses the needle valve to control the flow rate (e.g. 5-30 L/min) of the gas outputted from the flow stabilizer 20 in order to stably output the gas.
The eductor 30 is connected to the flow stabilizer 20 and the tail gas exhausting outlet 16 so as to receive the gas outputted from the flow stabilizer 20 and convey the gas to the tail gas exhausting outlet 16 via a tail gas exhausting hose 31.
The safety relief valve 70 is disposed between the safety outlet 15 and the gas distribution tube 11. When the gas pressure value of the gas inside the safety relief valve 70 is greater than an exhausting threshold value (e.g. ⅓ psiG (psi Gauge)), the safety relief valve 70 is turned on and the gas can be exhausted via the safety outlet 15. As the pressure of the gas inside the gas distribution tube 11 is excessively high, the equipment connected to the gas distribution tube may be damaged or a danger may be caused. The safety relief valve 70 and the safety outlet 15 can stabilize the pressure of the gas inside the gas analyzer connected to the tail gas exhausting pressure stabilization control system in order to avoid the above situation.
The driving gas flowing tube 12 is connected to the driving gas supplying end 14 to receive the driving gas. When the energy-saving pressure regulator 40 detects a back pressure, the energy-saving pressure regulator 40 adjusts the pressure of the driving gas outputted to the eductor 30 in accordance with the detecting result of the back pressure. Besides, the energy-saving pressure regulator 40 can increase the pressure of the driving gas, such that the pressure of the driving gas inputted into the energy-saving pressure regulator 40 can be less than the pressure of the driving gas outputted from the energy-saving pressure regulator 40 (e.g. 1:6). In this way, when the pressure of the outputted driving gas is increases, the flow rate of the outputted driving gas is also increased accordingly. Thus, the pressure of the driving gas and the flow rate thereof can be effectively saved via the adjustment in accordance with the detecting result of the driving gas and/or the pressure increasing function of the energy-saving pressure regulator 40.
When the driving gas is inputted into the eductor 30, a corresponding pressure is generated. Therefore, when the eductor 30 receives the pressure provided by the driving gas, a corresponding vacuum pressure is generated. Thus, the eductor 30 can draw the corresponding gas via the vacuum pressure, such that a mixed gas is formed by mixing the gas with the pressure gas and the mixed gas is exhausted to the tail gas exhausting outlet 16.
The pressure regulator/distributor 16 is connected to the driving gas flowing tube 12 in order to receive the driving gas from the driving gas flowing tube 12. Then, the pressure regulator/distributor 60 adjusts the pressure of the driving gas to an adjusted pressure (e.g. 20 psiG) and then outputs the driving gas.
The energy-saving pressure control loop 50 is connected to the pressure regulator/distributor 60, the energy-saving pressure regulator 40 and the tail gas exhausting hose 31. The energy-saving pressure control loop 50 receives the driving gas, outputted by the pressure regulator/distributor 60, from the energy-saving pressure compensation module 51, and outputs the driving gas to the tail gas exhausting hose 31. Accordingly, the driving gas and the mixed gas outputted by the eductor 30 can be outputted at the same time. However, when the mixed gas is outputted to the tail gas exhausting outlet 16, the back pressure is (or is not) applied to the tail gas exhausting outlet 16; thus, when the back pressure exists, the back pressure would press the tail gas exhausting outlet 16 in the direction toward the tail gas exhausting hose 31. Accordingly, the energy-saving pressure compensation module 51 receives the back pressure from the tail gas exhausting hose 31 via the energy-saving pressure control loop 50 for the energy-saving pressure regulator 40 detects the back pressure and generates the detecting result of the back pressure.
Further, the energy-saving pressure control loop 50 is further provided with the energy-saving pressure compensation module 51 and the energy-saving pressure compensation module 51 includes a flow limiting micro-tube. The flow limiting micro-tube receives the driving gas from the pressure regulator/distributor 60 with a view to stabilize the pressure of the driving gas. A back-pressure valve is disposed between the micro-pipe flow limiting and the tail gas exhausting hose 31 so as to receive the driving gas outputted by the flow limiting micro-tube and then output the driving gas to the tail gas exhausting hose 31. Thus, the back-pressure valve is used to unidirectionally output the driving gas to the tail gas exhausting hose 31. However, if the energy-saving pressure control loop 50 is pressed inward after receiving the back pressure, the back-pressure valve can further prevent the back pressure from be applied toward the flow limiting micro-tube. When the back pressure presses the output of the back-pressure valve, the driving gas needing to be outputted from the back-pressure valve cannot be successfully outputted because of the back pressure. Therefore, the pressure of the driving gas between the pressure regulator/distributor 60 and the energy-saving pressure compensation module 51 would gradually increase because the driving gas cannot be outputted. At the moment, the energy-saving pressure regulator 40 can detect the increased pressure of the driving gas so as to indirectly detect the increased pressure force due to the back pressure. In this way, the energy-saving pressure regulator 40 can detect the back pressure (either by direction detection or indirect detection) to generate the detecting result of the back pressure in order to adjust the pressure of the driving gas outputted to the eductor 30 and then resist the back pressure.
Moreover, the present invention further provides a vacuum micro-regulator 32 and a gas stabilization/compensation valve 80. The vacuum micro-regulator 32 is majorly used to balance the pressure between the gas and the driving gas. The gas stabilization/compensation valve 80 is majorly used to compensate for the output flow rate of the gas in order to avoid that a vacuum space is gradually formed in the gas distribution tube 11 because the flow rate of the gas is insufficient.
One end of the vacuum micro-regulator 32 is connected to the energy-saving pressure control loop 50 and the other end thereof is connected to the connection point between the flow stabilizer 20 and the eductor 30. Accordingly, the vacuum micro-regulator 32 can receive a portion of the driving gas or the back pressure from the energy-saving pressure control loop 50 so as to convey the driving gas or the back pressure to the eductor 30 via the gas outputted from the flow stabilizer 20. Therefore, the eductor 30 can output the driving gas or the back pressure to the tail gas exhausting outlet for the purpose of achieving pressure balance.
The gas stabilization/compensation valve 80 is connected to the pressure regulator/distributor and the gas distribution tube 11 so as to receive the driving gas form the pressure regulator/distributor 60. Then, the gas stabilization/compensation valve 80 adjusts the pressure of the driving gas to a compensation pressure (e.g. 1 inch-WC) and outputs the driving gas to the gas distribution tube 11. More specifically, if the original flow rate of the gas distribution tube 11 is 5 L/min and the tail gas inlet 13 can only provide the gas by the flow rate of 4 L/min, the gas distribution tube 11 would gradually generate some vacuum pressure because its original flow rate of 5 L/min is not satisfied. In this case, since the gas stabilization/compensation valve 80 has received the driving gas from the pressure regulator/distributor 60 and performed the relevant pressure adjustment operations (if the pressure adjustment operations fail to be made, the driving gas may not effectively provide the compensation function for the gas), the gas distribution tube 11 can receive the driving gas from the gas stabilization/compensation valve 80 to make up the shortage (1 L/min) of the flow rate of the gas so as to achieve compensation effect.
In accordance with the above embodiment, the present invention can effectively stabilize and maintain the pressure and flow rate of the gas of the tail gas exhausting outlet 16 and the gas distribution tube 11, and simultaneously save the driving gas.

In the second embodiment, the arrangement of the components for gas compensation and exhausting gas is different from that of the first embodiment. More specifically, the safety relief valve 70 is disposed between the gas stabilization/compensation valve 80 and the safety outlet 15. The gas stabilization/compensation valve 80 is disposed between the pressure regulator/distributor 60, the gas distribution tube 11 and the safety relief valve 70, such that the gas stabilization/compensation valve 80, the pressure regulator/distributor 60 and the gas distribution tube 11 are connected to the safety relief valve 70. Thus, the safety relief valve 70 cannot directly receive the gas, but can receive the gas via the gas stabilization/compensation valve 80 and output the gas to the safety relief valve 70.
The gas stabilization/compensation valve 80 is used to receive the driving gas from the pressure regulator/distributor 60 via the gas stabilization/compensation valve 80 when the flow rate of the gas in the gas distribution tube 11 is insufficient. Then, the gas stabilization/compensation valve 80 can provide the driving gas for the gas distribution tube 11 in order to compensate for the shortage of the flow rate of the gas. On the contrary, if the gas in the gas distribution tube 11 is too much and exceeds the compensation pressure set by the gas stabilization/compensation valve 80 (e.g. 1 inch-WC), the gas in the gas distribution tube 11 would be pressed in the direction toward the gas stabilization/compensation valve 80. Meanwhile, the safety relief valve 70 can receive the gas in order to determine whether the gas pressure value of the gas is greater than the exhausting threshold value (e.g. 7 inch-WC). If it is, the safety relief valve 70 is turned on and then the gas can pass through the safety relief valve 70 and be exhausted from the safety outlet 15.
As described above, in accordance with the arrangement of the second embodiment, the pressure value setting of the compensation pressure is usually less than the safety pressure setting of the exhausting threshold value, which can just achieve the compensation and gas exhausting effects by the same pipeline.
In the third embodiment, the arrangement of the components for exhausting gas is different from that of the first embodiment. More specifically, the third embodiment further includes a pressure detector 71 and an exhausting controller 72. The pressure detector 71 is majorly used to detect the pressure and determines whether the pressure is greater than the exhausting threshold value; then, the pressure detector 71 generates a signal S and transmits the signal S. The exhausting controller 72 is majorly used to determine whether to turn on the safety relief valve 70 in accordance with the received signal S.
Further, the pressure detector 71 is disposed on the gas distribution tube 11 and wiredly or wirelessly connected to the exhausting controller 72 so as to detect the gas pressure value in the gas distribution tube 11. Besides, the pressure detector 71 can generate the signal S in accordance with the detecting result and then transmits the signal S to the exhausting controller 72.
The exhausting controller 72 is further connected to the safety relief valve 70. When the gas pressure value of the gas received by the exhausting controller 72 is greater than the signal S of the exhausting threshold value, the exhausting controller 72 turns on the safety relief value 70, such that the gas in the gas distribution tube 11 passes through the safety relief valve 70 and is exhausted from the safety outlet 15.
As set forth above, both of the second embodiment and the third embodiment can effectively stabilize and maintain the pressure and flow rate of the gas of the tail gas exhausting outlet 16 and the gas distribution tube 11, and simultaneously save the driving gas.

Furthermore, the pressurizing component 90 is connected to the flow stabilizer 20 and the tail gas exhausting outlet 16. The pressurizing component 90 can draw the gas outputted by the flow stabilizer 20 and convey the gas to the tail gas exhausting outlet 16.
The vacuum regulation component 91 is disposed between the pressure regulator/distributor 60 and the pressurizing component 90 with a view to adjust the gas pressure value of the tail gas exhausting hose 31 between the vacuum regulation component and the pressurizing component 90 to an adjustment threshold value (e.g. the adjustment threshold value may be −6″ G). The gas may be outputted by the flow stabilizer 20 to the pressurizing component 90 under a negative pressure (e.g. −6″ HG). Therefore, if the pressure of the tail gas exhausting hose 31 is adjusted to −6″ HG, the pressure of the driving gas outputted to the pressurizing component 90 can be effectively stabilized.
One end (the first end) of the bypass module of pressurizing component 92 is connected to the connection point between the flow stabilizer 20 and the pressurizing component 90, and the other end thereof (the second end) is connected to the connection point between the pressurizing component 90 and the tail gas exhausting outlet 16. Thus, when the pressurizing component 90 outputs the gas, the driving gas or the mixed gas (the following content takes the mixed gas as an example), the mixed gas returns from the second end of the bypass module of pressurizing component 92 to the first end of the bypass module of pressurizing component 92. When the mixed gas returns to the bypass module of pressurizing component 92, the bypass module of pressurizing component 92 can further control the flow rate of the mixed gas and then output the mixed gas to the first end of the bypass module of pressurizing component 92, such that the pressurizing component 90 receives the mixed gas again to form the loop in order to balance the pressure between the front end and the rear end of the pressurizing component 90.
In accordance with the embodiments set forth above, the tail gas exhausting pressure stabilization control system in accordance with the present invention can actually stabilize and maintain the pressure and flow rate of the gas, and can simultaneously save the driving gas.
