Description

The utility model relates to the field of electricity and can be used to generate electricity when discharged treated wastewater into natural water bodies.

A device for a hydroelectric power station (HPP) is known, including a dam creating a difference in water levels in a natural body of water; channels leading water to the hydraulic turbine and diverting water from it to the downstream; a hydraulic turbine connected to an electric generator; a building in which a hydraulic turbine with an electric generator is installed can be built into the dam or located at some distance from the dam (see Baptidanov L.N., Tarasov V.I. Power plants and substations. Edition 2 revised - M: Energy , 1969.442 s.).

The most expensive and complex element of a hydroelectric power station is a dam, in addition, when creating a difference in water levels, a reservoir forms that floods vast areas and subsequently creates adverse environmental consequences.

The closest device of the same purpose to the claimed utility model in terms of all the features is the device of a derivative hydroelectric power station, including a dam, a water supply pressure pipe, a hydraulic turbine connected to an electric generator, water drainage to the downstream pipe (see Baptidanov L.N., Tarasov V .I. Power plants and substations. Edition 2 revised - M: Energy, 1969. 424 pp.) And adopted as a prototype. For reasons that impede the achievement of the following technical result when using the known device adopted for the prototype, is that the known device has

a dam, which is located above the location of the power plant and is an expensive and complex element of a derivative hydroelectric power station; it is not possible to completely exclude the creation of a reservoir in the upper pool; the need to build a derivation pipeline; the need to regulate the level in the reservoir.

The essence of the utility model is as follows:

After the treatment of sewage in sewage treatment plants, they are discharged through a pipeline system into natural water bodies. In many cases, water bodies are located much lower than treatment facilities. The difference between the level of the location of treatment facilities and the level of the surface of the water in a natural body of water can reach several tens of meters. Recycling hydroelectric power station is located near the pipelines for the release of treated waste water. The volume of runoff in large cities is measured in units or tens of cubic meters per second. Therefore, the effluents discharged into natural water bodies have a sufficiently large kinetic energy, the power of which is determined by the well-known expression

N = ρ · Q · H · g · 10 ^-3 kBt,

where: ρ is the fluid density in kg / m ³ , Q is the volume of effluents in m ³ / s, N is the difference in levels in m, g is the acceleration of gravity in m / s ² .

This energy is not useful.

EFFECT: obtaining electric energy by using the kinetic energy of treated sewage discharged into a natural body of water with lower costs.

The specified technical result in the implementation of the utility model is achieved by the fact that in the known device including a dam, a water supply pressure pipe, a hydraulic turbine connected to an electric generator and a water discharge pipe, a water supply pipe is laid from the dam located above to the installation site of the turbine, and outlet pipe

waste water in the turbine is discharged to the downstream. The peculiarity lies in the fact that the water supply pressure pipe and the water discharge pipe cut into the sewage discharge pipe, on which a shutter is installed between the insets. Water is supplied to the turbine through the inlet pressure pipe. The pressure water supply line is equipped with a pre-turbine valve and an expansion joint to prevent linear deformation of the water conduit. The sewage discharge pipe is also equipped with an expansion joint. Exhaust water from the turbine is discharged to a discharge well, from which a drainage pipe of the corresponding section equipped with an expansion joint is diverted to the discharge pipe behind a valve installed on it below the level of the discharge well.

In order to ensure normal operating conditions for electric and hydraulic equipment, the equipment of the hydroelectric power station is located in the building of the hydroelectric power station, which can be constructed from lightweight prefabricated structures.

The power plant is equipped with protection and automation devices, allowing to work in fully automatic mode, and a device for delivering electric power to the electric network or transmitting it to a dedicated consumer.

In addition, a feature of the utility model is that it can be used to generate electricity when drinking water is supplied to the city if it is supplied with excess pressure from a reservoir located above.

The drawings show:

Figure 1 shows a section 1-1 of the station node.

Figure 2 shows the layout of the station node.

Information confirming the feasibility of implementing the utility model with obtaining the above technical result is as follows.

The utility model contains a hydraulic unit consisting of a hydraulic turbine 1 coupled to an electric generator 2; water supply pressure pipe 3; pre-turbine shutter 4; stuffing box compensator 5; discharge well 6; water discharge pipe 7 with stuffing box compensator 8; building 9 power plants; power output device 10; power line 11. The water supply pressure pipe 3 and the water discharge pipe 7 are cut into the lower part of the treated sewage discharge pipe 12, onto which a shutter 13 and an stuffing box 14 are installed between the insets.

The operation of the device is as follows. The pre-turbine shutter 4 opens and the shutter 13 is installed, installed on the pipeline 12 for the release of treated wastewater. In this case, the discharged water passes through a hydraulic turbine 1 and drives a turbine with an electric generator 2, which generates electricity. The waste water from the hydraulic turbine 1 is discharged into a discharge well 6, from which through a water discharge pipe 7 it is discharged into the exhaust pipe 12 behind the shutter 13 installed thereon below the level of the discharge well 6. The electricity generated by the electric generator 2 is supplied through the power output device 10 to the power transmission line 11 .

The building 9 of the hydroelectric station houses devices for automatic control of the hydraulic unit, excitation, auxiliary panel and other auxiliary devices.
