Description of numbering:
a regulation and storage tank 1; a siphon 2; a float valve 3; a regulating reservoir water inlet branch pipe 4; an electric butterfly valve 5; a vacuum pump 6; an overflow port 7; a water inlet lift pump 8; a ventilation solenoid valve 9.
Detailed Description
Storage tank (1): the concrete pool body is built in the top space of the water collecting pool of the water inlet pump station. A hoisting space is reserved for the lifting water inlet lifting pump (8). The hydraulic retention time of the storage tank (1) is not less than 2h of the flow of the design scale, so that the purpose of storage regulation is achieved.
Siphon (2): the U-shaped structure is inverted, one end of the U-shaped structure is immersed at the bottom of the regulation and storage tank (1), the other end of the U-shaped structure is immersed at the bottom of the water inlet channel at the front end of the water collecting tank, and the top of the U-shaped structure is exposed at the top of the water collecting tank. Used for releasing the sewage quantity of the regulation and storage tank and balancing the water quantity in different time periods.
Float valve (3): install on regulation pond (1) inlet tube, can control the liquid level in regulation pond (1), when reacing high liquid level, inlet tube is closed in ball-cock assembly (3), stops into water. When the liquid level is lower than the high liquid level, the float valve (3) is opened, and water can be fed.
Regulating reservoir inlet branch pipe (4): connect and promote pump station outlet pipe and regulation pond (1) import for reach the peak value flow condition at the pump station of intaking and carry the sewage of excess to regulation pond (1), do not intake when being less than average flow.
Electric butterfly valve (5): is arranged on the water inlet branch pipe (4) of the storage tank and the front end of the float valve (3). The electric butterfly valve (5) is controlled by a liquid level meter in the water collection tank of the water inlet pump station, and the electric butterfly valve (5) is opened when the liquid level is high; when the normal liquid level is closed, the regulating and storing tank (1) does not feed water although the ball float valve (3) is opened.
Vacuum pump (6): the device is arranged on the top of the storage tank (1) and used for sucking air on the top of the siphon (2) and realizing the release and stop of sewage in the storage tank (1) by controlling the formation and the destruction of the siphon. The vacuum pump (6) is controlled by a liquid level meter in a water collecting pool of the water inlet pump station, and is started when the water collecting pool reaches a pump stopping liquid level and stopped at a high liquid level. The siphon (2) releases water volume under the condition of low flow and stops under the condition of high flow, thereby realizing the function of balancing the imbalance of peak-valley water volume.
Overflow pipe (7): under the abnormal condition, the regulation pond is filled with water and then is continuously fed, and in order to avoid the overflow to the ground, the water reaches the position of the pipe opening of the overflow pipe (7), and is forcibly discharged to the water collecting pond of the water inlet pump station.
Water inlet lift pump (8): the submersible sewage pump is arranged at the bottom of the pump station water collecting tank and used for lifting sewage to enter a factory for treatment.
Vent solenoid valve (9): the siphon pipe (2) is arranged at the top of the siphon pipe (2) and can break the siphon, and the siphon pipe (2) stops draining. Used for controlling the release and stopping of the release of the sewage in the storage tank (1). Is controlled by a water collecting tank liquid level meter of the water inlet pump station. The high liquid level in the water collecting tank is opened to destroy siphon, and the low liquid level is closed to realize siphon condition. Realize when the inflow is big, regulation pond (1) does not discharge water, avoids circulation suction and discharge, causes the energy extravagant.
Beginning of water storage
The liquid level reaches high liquid level in the pump station catchment pond of intaking, starts reserve elevator pump (8) of intaking, and electric butterfly valve (5) are opened simultaneously, and regulation pond (1) is intake.
Stopping water storage
When the liquid level in the water collecting tank of the water inlet pump station is reduced to the normal liquid level, the electric butterfly valve (5) is closed, and the regulating and storing tank (1) stops water inlet.
When the liquid level in the storage tank (1) reaches a high liquid level, the ball float valve (3) is closed, and water inflow is stopped. At the moment, the electric butterfly valve (5) is in an open state, and water cannot enter.
Drainage of regulation and storage tank
When the liquid level in the water collecting pool of the water inlet pump station is reduced to the liquid level of the pump stop, the water inlet lifting pump (8) stops the pump completely. And (3) starting the vacuum pump (6), closing the ventilation electromagnetic valve (9), discharging air in the siphon pipe (2) to form siphon, and discharging the sewage in the storage tank (1) into a channel at the front end of a water collecting tank of the pump station and then into the pump station. At the moment, the water inlet lifting pump (8) is completely stopped, and water cannot be simultaneously fed and drained in the storage tank (1) along with the rise of the liquid level until the liquid level reaches a high liquid level.
Stopping the drainage
When the sewage in the storage tank (1) is completely discharged, the drainage is stopped.
When the high liquid level condition of the water collecting tank of the water inlet pump station opens the electromagnetic valve (9), the siphon is broken, and the water discharge is forcibly stopped. The water is prevented from entering the storage tank (1) and is drained at the same time.
The underwater component adopts 304 and above standard stainless steel, thereby avoiding corrosion. The vertical pipe of the siphon has strong drainage capacity, and in order to avoid impacting the bottom of a structure and reduce noise, energy dissipation measures are added to a drain outlet of the siphon. The height difference of the top of the siphon pipe from the liquid level of the channel in front of the collecting tank is not more than 10m, if the height difference exceeds 10m, a water outlet well is added at the outlet (in the channel) of the siphon pipe, the pipe orifice is immersed in the well, and the liquid level in the well is raised, so that the height difference is not more than 10 m.
