Water taking-out method and automatic scrubbing apparatus by urban sewage low-order heat energy

Abstract

A method for taking water from the sewage pipe in urbane area by use of the potential difference between said sewage pipe and automatic sewage treating apparatus features that said sewage automatically flows into the automatic sewage treating apparatus to obtain clean water. Said automatic sewage treating apparatus is composed of orifice-plate filter cylinder, motor, speed reducer, overflow port, blowoff pipe, water spraying pipe, submersible pump, circulating pump, blowoff pump, etc.

Description

technical field [0001] The invention belongs to the technical field of natural energy utilization, and relates to a sewage water intake method and an automatic decontamination device, in particular to a water intake method and an automatic decontamination device for utilizing low-level heat energy of sewage in urban sewage pipe networks. Background technique [0002] Urban sewage is an available low-temperature energy source, especially untreated urban sewage has not yet been developed and utilized on a large scale. In recent years, although my country's water source heat pump technology has developed rapidly, it is limited by the shortage of water resources. Therefore, the development and utilization of urban sewage, a low-temperature energy source, has increasingly attracted people's attention. Compared with groundwater water source heat pumps, sewage water source heat pumps do not need to pump groundwater from the ground, nor do they need to refill the ground with circula...

AI Technical Summary

Problems solved by technology

The invention uses the potential energy difference between the urban sewage pipe network and the automatic decontamination device to make the sewage flow into the automatic decontamination device along the sewage inlet pipeline, and uses the orifice filter cartridge to block the dirt and debris; the orifice filter cartridge and the The matching water spray pipeline and sewage pipeline solve the problem of dirt and sundries blocking the heat exchanger when extracting energy from untreated urban sewage; large-area low-speed filtration makes it easier to obtain better filtration effects; The high-speed water flow backwashes the orifice plate filter cartridge, which has a better effect of removing dirt and debris; the outlet of the drainage pipeline can be set at any position downstream of the urban sewage pipe network relative to the sewage inlet pipeline, so that the sewage water intake and drainage are completely separated , to avoid the short-circuit problem at the mouth of the suction and discharge pipes in the water intake device
