1. Field of the Invention
This invention relates to an oil mist separator.
2. Description of the Prior Art
Generally, a medium or large catering industry frequently causes much lampblack during operation, and a factory also frequently causes much oil mist during operation when using cutting oil or cooling oil. In order to avoid the lampblack and oil mist from causing turbid air indoors and then affecting an operator's mood and even endangering a human body, a kitchen ventilator is installed in the environment to extract the lampblack and oil mist.
However, the way of using the kitchen ventilator to directly extract the lampblack and oil mist to the outdoors will do serious harm to the environment. Although there is filter net installed on an exhaust passage in reaching the effect of filtering, the effect is limited. When being used for a period of time, the filter net is blocked and must be replaced, and especially when being used in a work environment where the oil mist is caused, the filter net is even replaced frequently, which puts the working personnel to annoyance. Further, the replaced filter net that is stained with greasy dirt has to be thrown away, which indirectly pollutes the environment and does not meet the requirement of environmental protection. Thus, it is really necessary to provide a means of effectively filtering the oil mist without using the filter net, and then collecting the extracted oil mist.
Consequently, because of the technical defects of described above, the applicant keeps on carving unflaggingly through wholehearted experience and research to develop the present invention, which can effectively improve the defects described above.
An oil mist separator according to this invention mainly comprises a body inside which a container is formed. A first spacer and a second spacer are formed in an inner layer of the container to form an exhaust chamber, a filtering chamber, and an oil collection chamber from top to bottom in the container. Further, through an air intake unit serving as an air blower, the oil mist is directly transmitted to the filtering chamber. Next, through a filtering unit, the oil mist is separated. The filtering unit is made up with several centrifugal dust collectors. Each of the centrifugal dust collectors is mainly provided with a hollow duct. One end of the duct is forwards convergent and formed into a convergent portion of which the end is formed with a mouth, while the other end of the duct is covered with a lid. A hollow nozzle going axially along the duct is provided passing through the lid. The two ends of nozzle are respectively formed into a guidance inlet and a guidance outlet. The guidance inlet lies in the convergent portion. Besides, one side of the body is formed with a prolonged portion parallel with its axis. A flowing passage communicating with the duct is formed in the prolonged portion, and a flowing port is formed at a free end of the prolonged portion. Further, the mouth of centrifugal dust collector passes through the first spacer. A guidance outlet of the centrifugal dust collector passes through the second spacer. Thus, the oil mist sent into the air intake unit may enter the duct from the flowing port and go spirally forward to the mouth along the inner wall of duct to form a spiral air stream, and with a centrifugal force caused by the spiral air stream, the oil mist of which the mass is heavier than the air is made to separate from the air and enters the oil collection chamber of the body from the mouth for collection and recovery. Then, the air of zero pollution that separates from the oil mist enters the exhaust chamber from the nozzle and, after being gathered in the exhaust chamber, is extracted to the outdoors. Thus, no filter net is required and the oil mist may even separate from the air, which protects the environment, and the oil mist separator is designed with modularity, so it is easy to assemble and repair. Further, the volume of oil mist separator is low and its profile is simple and of fashion; it is not abrupt even if the separator is used in a system kitchen. Next, the recycled oil mist may be made into a low-level oil product or a release agent used in the building industry for achievement of the effect of recycling.
Now, the present invention will be described more specifically with reference to the following embodiments.
