DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to the uses and applications of an in-pipe turbine in fluid systems.

Definitions

The current patent application deals with fluids. Unless otherwise stated, it refers to any kind of fluid: water, oil, gas, etc.

The principles and operation of an in-pipe turbine within a fluid system according to the present invention may be better understood with reference to the drawings and the accompanying description.

Referring now to the drawings, FIG. 1 illustrates an hourglass-like storage system. Here is presented the system of elevating a substance, particularly a solid, for the purpose of storing energy. The ideal substance would be sand, and, in one embodiment, the structure would be like all hourglass with two storage containers (1, 2) with at least one turbine (3) in the middle. Two in-pipe turbines could be used in series for higher efficiency. In another embodiment, said turbine would have a bidirectional input and unidirectional output gear (4) attached to the generator (5) so that the generator can generate energy from both sides of the “hourglass.” At least one gating structure (6, 7) to open and close the storage containers for access to the turbine should also be present. The device, when finished discharging energy, would gradually tilt back up as the energy used for storage is produced. A track (8) or a gear (9) in conjunction with a motor would enable incremental return to full storage capacity. Incremental return is important for storing whatever spare energy is present in a system, while continuous production of energy from storage is important for the user. Box (10) represents the electronic control that would receive instructions to store and release electrical energy. The solid or sand can also be wet. Here are some density values:

Sand, wet             1922
Sand, wet, packed     2082
Sand, dry             1602
Sand, loose           1442
Sand, rammed          1682
Sand, water filled    1922
Sand with Gravel, dry 1650
Sand with Gravel, wet 2020

An hourglass-type of structure is not the only solution. FIG. 2 illustrates a conveyor system to elevate the substance to the top of a high pipe (11) in such a system. At least one turbine (12) in the pipe or attached to the pipe provides electricity. The substance empties into a conveyor belt of any kind, here represented as a coal-mining cart on wheels (13), which then ascends a track (14). This is representative only. It dumps its load at the top (15) into the pipe or a collector at the top. Gates at a number of spots can regulate the production of electricity, and the conveyor belt can operate little by hole as electricity becomes available.

Such systems can operate on or off grid.

Because these systems can be made relatively small and can operate with many different substances, some of which are denser than water, they enable great flexibility for grid control. They can also be used in desert areas. Deserts are defined as areas with an average annual precipitation of less than 250 millimetres (10 in) per year

Water systems have a need for many gauges, meters, etc. in order to operate the system. A new use is proposed for an in-pipe turbine—the generation of power for such applications. Any type of off-grid power generation is presented. The use of battery chargers and batteries connected to the generator and the turbine in order to hold electricity in cases of intermittent flow is presented. In addition, these individual uses can be connected to a smart water grid.

An in-pipe turbine has a new use as a pressure reduction valve equivalent to reduce excess pressure in the piping system. Its use in conjunction with a pressure valve to assure a steady input or output of pressure from the combined turbine and pressure valve system is hereby presented.

The method of decreasing the pressure before and after a propeller is hereby claimed, wherein a combination of at least nozzle size, nozzle shape, type (including shape, for example) of blade, and torque/rpm characteristics of the generator system are used to change the pressure precisely from entry to exit.

A new use for the city, utility, etc. sewage or fresh water system can be to hold energy within the system and release the fluids for energy during peak hours or other times of need. A series of in-pipe turbines connected to the electrical grid and the water grid through a microprocessor that also receives data derived from water and electrical sensors enables the interaction of two grids for the purpose of storing excess energy and providing it on demand. Currently, many utilities pump water up at night or at other non-peak times, but the new business method is the release of electricity during peak hours from within the water system, not merely an external storage facility. Use in the water system is defined as use in a location where the water is in conduit to perform the system's customary work of providing water to customers or treating it.

Computerized matching of supply and demand for water in the water system and/or electricity in the electrical system is a new use presented here.

The placement of a turbine in the condensation stage of a thermosyphon, as shown in FIG. 3, or any heating and cooling system, is hereby presented. This could provide a continuous supply of renewable energy from heat exchange. The earth (16) is relatively warm in cold climates at all times, and relatively cool in hot climates by day and warm at night. The level of the turbine (17a) is in one embodiment placed above the level of the fluid (18) which is at the bottom, so that the condensation above it (19) can move downwards (17) through it more easily. The situation can be artificially created, as by placing the system in sand. In the desert, at night, the air cools faster. It should be constructed so that the water in the cooler air condenses over the turbine and drips through it. That may involve selectively insulating the area where the evaporation to gas occurs, and decreasing the insulation (or increasing the circulation of cold air) over where the condensation area occurs.

Heating and cooling systems have a continuous flow of fluid, and the turbine can be placed in the downward conduit.

FIG. 4 is diagram of the matching of water and electrical grids. It shows how the components of a smart electrical and smart water system are connected. (Note: In the industry, a water grid is used synonymously and vernacularly to describe the conveyance system of pipes and other objects such as valves and tanks that are part of this system. In this usage, it is not meant to mean an electrical system.) Arrows show interactions. Double arrows show interactions in both directions. Solid lines show connections. Dotted lines show function. Non-electrical actions comprise data. A smart electrical grid (20) is connected to a microprocessor (22) and a smart water grid, or water conveyance system, (21) is attached to a microprocessor (23). These two microprocessing systems are connected to each other to trade information and commands in both directions. Element (27) indicates matching and information sharing between them. This indicates the purpose and the result of the operations. In-pipe turbines (24) are optionally connected to and part of the smart water grid (21). They also supply electricity under the control of the water grid's microprocessor via electrical connectors (25) to the smart electrical grid (20). The in-pipe turbines (24) may be corrected to battery chargers and batteries (28) for local operations und electrical storage. The smart electrical system (20) can be connected to its own storage system (26). Element (25a) indicates that electrical connectors exist between the two mid systems. This enables the matching of element (27).

FIG. 5 is a diagram of an hourglass-like storage system from another perspective to makes the structure clearer. Elements (29) and (30) are the containers. Element (31) is a pipe or connector structure. The gates of FIG. 1 are now shown here so that the picture is less cluttered. A motor (32), mounted on a support structure (33), here shown as legs in one embodiment, is fixedly connected to the center of the “hourglass” with element (34), which also shows a customary use of a central shaft, but it need not be done in that manner. The whole motor system is shown in dotted lines to show them clearly as an accompaniment to the motor. The power generation mechanism is shown more clearly in this perspective. The turbine (35) in the pipe is connected via a shaft (36) as is standard in the art to a generator (38) usually via a gear (37). The generator often has its own shaft (39) connected to the gear (37). As electrical wire (40) conveys the electricity from the generator.

While the invention has been described with respect to a limited number of embodiments, it will be appreciated that many variations, modifications and other applications of the invention may be made.
