In a sewage treatment plant, municipal sewage is directly discharged after being treated; the tail water is discharged with a certain fall, and the discharge flow of the sewage is large, so that the energy is wasted when the tail water is discharged. Such as: in a sewage treatment plant, when municipal sewage is discharged after being treated, the fall of tail water is about 1.5-5 meters, and the sewage discharge flow of most sewage treatment plants is 2-30 ten thousand tons/day or above the data;
therefore, the embodiment provides a sewage plant tail water power generation device 200 which can generate power by using tail water so as to generate better economic value, environmental value and social value, and can supply electric energy generated by tail water power generation to the operation of a sewage plant so as to reduce the operation cost in the plant.
Specifically, referring to fig. 1, the sewage plant tail water power generation device 200 includes a pressure relief well 210 and a power generation device 220;
a partition 211 is arranged in the relief well 210, and the partition 211 divides the relief well 210 into a first chamber 212 and a second chamber 213;
the power generation device 220 is disposed in the relief well 210; the power generation device 220 comprises a water inlet pipe 221, a water turbine 222, a water outlet pipe 223 and a power generator 224; the water inlet pipe 221 is connected with the partition 211, is positioned at the upper part of the partition 211, and is communicated with the first chamber 212; a water inlet of the water turbine 222 is communicated with the water inlet pipe 221, a water outlet of the water turbine 222 is communicated with the water outlet pipe 223, and the water outlet pipe 223 is communicated with the second chamber 213; the generator 224 is in transmission connection with the water turbine 222;
the tail water in the first chamber 212 is guided into the water turbine 222 through the water inlet pipe 221, and is guided into the second chamber 213 through the water outlet pipe 223 after the water turbine 222 is driven and the generator 224 in transmission connection with the water turbine is used for generating electricity.
The working principle of the sewage plant tail water power generation device 200 is as follows:
because the tail water has a certain fall in the discharging process, the generator 224 can be driven to generate electricity by utilizing the potential energy formed by the fall in the tail water discharging process and the kinetic energy of the tail water, and the electricity can be generated in such a way, and the electricity generated by the electricity generation can be supplied to other equipment in a sewage treatment plant, so that the running cost of the sewage treatment plant can be reduced;
specifically, in order to generate power during the tail water discharge process, the tail water power generation device 200 of the sewage plant includes a pressure relief well 210 and a power generation device 220; the power generation device 220 is arranged in the relief well 210;
moreover, a water inlet pipe 221 and a water outlet pipe 223 of the power generation device 220 are respectively communicated with the first cavity 212 and the second cavity 213 of the pressure relief well 210, and a water inlet and a water outlet of a water turbine 222 of the power generation device 220 are respectively communicated with the water inlet pipe 221 and the water outlet pipe 223; therefore, the tail water can be guided to move towards the water turbine 222 through the water inlet pipe 221, the impeller of the tail water is driven to rotate in the water turbine 222, the generator 224 in transmission connection with the water turbine 222 is further driven to generate electricity, and the tail water can be guided into the second chamber 213 through the water outlet pipe 223 after the impeller of the water turbine 222 is driven to rotate.
Therefore, the sewage plant tail water power generation device 200 can generate power by using tail water in the pressure relief well 210, so that energy waste in a sewage treatment process can be reduced.
It should be noted that, when the electric energy generated by power generation is supplied to other devices in a sewage treatment plant, the electric energy generated by the generator 224 needs to be output after the voltage and frequency of the electric control cabinet are adjusted, and then the stable electric energy output by the control cabinet is transmitted to each device after passing through the power distribution cabinet;
in this embodiment, in order to improve the corrosion resistance of the power generation device 220, so as to improve the working life of the power generation device 220 in the pressure relief well 210, when the power generation device 220 is arranged, the water inlet pipe 221, the water turbine 222, the water outlet pipe 223 and the power generator 224 are all provided with an anticorrosive layer, and the anticorrosive layer may be an anticorrosive paint layer or an anticorrosive material layer arranged on the surface of the aforementioned structure; in other embodiments of the present invention, other methods may be used to perform the corrosion protection treatment on the power generation device 220.
Further, in the present embodiment, when the hydraulic turbine 222 and the generator 224 are drivingly connected, the power generation device 220 further includes a driving belt 225, and the driving belt 225 is drivingly connected to the generator 224 and the hydraulic turbine 222.
In addition, in the present embodiment, the power generation device 220 further includes a first on-off valve 226 disposed on the water inlet pipe 221, and a second on-off valve disposed on the water outlet pipe 223. By such an arrangement, it is possible to temporarily input and output water when the power generation device 220 is in the maintenance stage, so as to facilitate maintenance thereof. Also, in this process, in order to guide out the water in the first and second chambers 212 and 213, the sewage plant tail water power generation apparatus 200 further includes a first drain pipe disposed at the bottom of the first chamber 212 and discharging the tail water in the first chamber 212. In addition, the sewage plant tail water power generation apparatus 200 further includes a second drain pipe disposed at the bottom of the second chamber 213 and discharging tail water in the second chamber 213.
It should be noted that, when the power generation device 220 is in the maintenance stage, it does not have the function of generating power, so that the device electrically connected to the generator 224 can be switched to the utility power supply line, that is, the device operates by the utility power.
Further, in the present embodiment, when the water turbine 222 is provided, the structure of the impeller of the water turbine 222 needs to be specially processed to meet the requirements of the hydro-generator 224 with a small water head and a small flow rate; therefore, the guide vanes on the impeller of the water turbine 222 form an included angle of 65 degrees with the center line of the impeller, and a conical water distributor is adopted, namely, the shell of the water turbine 222 is in a gradually reduced conical shape from the water inlet pipe 221 to the water outlet pipe 223.
In addition, in order to reduce water conservancy loss, water flow can flow into the runner in parallel with the axial direction of the water turbine 222, so that the water conservancy loss can be reduced as much as possible, a conical water distributor is uniformly introduced to form ideal annular quantity to enter the runner chamber, and then the ideal annular quantity is efficiently converted into mechanical energy of the water turbine 222; therefore, the water inlet pipe 221 is disposed in a horizontal direction, and water introduced into the water turbine 222 from the water inlet pipe 221 flows into the water turbine 222 in a direction parallel to the axial direction of the water turbine 222, and the water outlet pipe 223 is a tapered pipe, and the opening area of one end of the water outlet pipe 223 connected to the water outlet is smaller than that of the other end thereof.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
