A Waste Heat Utilization System of Urban Sewage Pumping Station

Abstract

The invention discloses a waste heat utilization system of an urban sewage pumping station. The system comprises a waste heat utilization device, a heating water pipeline, a heating water pump, a valve and a filter screen. The heating water enters the waste heat utilization device from the nearby heat users through the heating water pipe, and the waste heat utilization device fully contacts with the sewage to heat the heating water. Conditioned and returned to the hot user. Most of the locations of urban sewage pumping stations are distributed in grids in various areas of the city. This invention utilizes the unique geographical location of urban sewage pumping stations and utilizes the waste heat of sewage on a large scale, which can realize heating for users within a certain radius around it, and can significantly reduce urban energy consumption for district heating and save investment.

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
