Water source heat pump system based on sewage source

Abstract

The invention discloses a water source heat pump system based on a sewage source. The water source heat pump system comprises a factory, a sedimentation tank and a sewage source heat pump unit, sewagedischarged by the factory is connected with the water inlet end of the sedimentation tank through an arranged sewage discharge pipe, the sewage source heat pump unit is connected with the water outlet end of the sedimentation tank through an arranged connecting pipe, and the water inlet end of the factory is connected with the water outlet end of the sewage source heat pump unit through an arranged hot water pipe. Through the arrangement of the sedimentation tank, sewage flows into the periphery of a sewage tank in the radiation direction from top to bottom, sedimentation of sludge in the sewage is facilitated, the sludge and dregs in the sewage can be effectively precipitated, the sludge can be cleared away, a sewage clearing mechanism can prevent a water inlet of the connecting pipe from being blocked, the effect is good, the filtering mechanism can effectively filter out other particles in the sewage, and an anti-backflow mechanism can prevent the sewage from flowing back; and according to the water source heat pump system, the application environment and the overall performance of the system are greatly improved, sewage of factories is effectively utilized, the utilization efficiency of energy is improved, and the water source heat pump system is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of sewage source heat pumps, in particular to a water source heat pump system based on sewage sources. Background technique [0002] The sewage source heat pump system uses the energy in the sewage as the low-level energy, through a small amount of electric energy input, adopts non-clogging sewage heat exchange and heat pump technology, and develops and utilizes the low-level heat energy that is not easy to use in the sewage to make it available. High-level heat energy , to meet the needs of residents or factories. [0003] At present, the circulating water used in the sewage source heat pump system is mostly ground water or factory sewage. Using groundwater or factory sewage as circulating water, due to unstable water quality, such as too high sediment content, or too fine sand, has a great destructive effect on the unit, and even the host cannot be used after installation, and the main unit must be replac...

AI Technical Summary

Problems solved by technology

Using groundwater or factory sewage as circulating water, due to unstable water quality, such as too high sediment content, or too fine sand, has a great destructive effect on the unit, and even the host cannot be used after installation, and the main unit must be replaced. It is also necessary to pump the groundwater to the surface. Using a head pump with a height of 80-120 meters consumes a lot of power. Not only that, the deep water pump is soaked in the well all the year round, and rust and damage are commonplace. It takes more than 10 days to repair once, and the pump is pulled out again, which is a waste of manpower, material and financial resources.
