Urban sewage pump station waste heat utilization system

Abstract

The invention discloses an urban sewage pumping station waste heat utilization system. The waste heat utilization system comprises a waste heat utilization device, a heating water pipeline, a heating water pump, a valve and a filter screen. Heating water enters the waste heat utilization device through a heating water pipeline from a nearby heat user, the waste heat utilization device makes full contact with sewage so as to heat the heating water, the temperature of the heating water is increased by about 15-18 DEG C after the heating water comes out of the waste heat utilization device, and then the heating water returns to the heat user after flow adjustment. The urban sewage pump stations are mostly distributed in all areas of a city in a gridding mode, the unique geographic positions of the urban sewage pump stations are utilized, waste heat of sewage is utilized in a large-scale mode, heating of users within a certain radius around the urban sewage pump stations can be achieved, energy consumption of urban area heating can be remarkably reduced, and investment is saved.

Description

technical field [0001] The invention belongs to the technical field of energy saving and heating, and relates to a waste heat utilization system of an urban sewage pumping station. Background technique [0002] The front section of the existing urban sewage treatment system mostly lifts the collected urban sewage through sewage pumping stations, and then sends it to the terminal sewage treatment plant for treatment through gravity relay. According to the operation data of the sewage system, the incoming water temperature of most sewage pumping stations has considerable sensible heat relative to the ambient temperature, which is often about 20 degrees Celsius higher than the ambient temperature in winter. High utilization value. Usually, in order to efficiently collect urban sewage, the geographical location of sewage pumping stations is usually arranged in grids in various areas of the city, serving the surrounding areas in a radial manner, and has good geographical conditi...

AI Technical Summary

Problems solved by technology

[0003] However, the waste heat of the existing urban sewage pumping station has not been fully utilized, causing this part of heat to be wasted

The main reason is that in the urban sewage pumping station, the water inlet intersection well, grille room, and sump are all located underground, and the space is relatively small, which is not conducive to the layout of equipment; at the same time, the self-flowing sewage may be blocked in the process of passing through the process facilities And then affect the operation of the pump station itself
