Sewage treatment heat pump

Abstract

A heat pump for sewage treatment, including a sewage treatment device and a heat pump device, the heat pump device includes a compressor, a waste heat exchanger, an evaporator, a condenser, a vacuum sewage tank and a U-shaped pipe, a water separation tank, a first heat exchanger, a vacuum Sewage tank, U-shaped pipe and evaporator are connected through pipelines to form the first circuit in turn, water distribution cylinder, condenser, second heat exchanger and sewage treatment device are connected through pipelines to form the second circuit, compressor, The condenser, the third heat exchanger and the sewage treatment device are sequentially connected through pipelines to form a third circuit, and the evaporator and condenser are connected with the user's air conditioner through pipelines. The sewage treatment heat pump of the present invention uses the cold water produced in the sewage treatment process as a cold source to be used by users for air conditioning in summer. In winter, the waste heat generated by the condenser is used to provide users with a heat source for heating in winter. Sewage treatment heat pumps have high energy-saving efficiency. Municipal sewage pipelines and large-scale sewage treatment plants may not be built, which reduces a lot of investment for construction units.

Description

Technical field [0001] The invention relates to a heat energy extraction system, in particular to a sewage treatment heat pump. Background technique [0002] The usual sewage treatment system is purely for the purpose of treating domestic sewage and is generally built on the ground. Municipal sewage pipelines and surface sewage treatment facilities need to be established, and the construction unit has a relatively large investment. [0003] The general heat pump system requires separate reinvestment in the configuration of air-conditioning and heating equipment, and requires the drilling of matching wells. Heat pumps that use well water to extract heat usually have uneven energy-saving efficiency due to various reasons. Moreover, it is inevitable that some areas will experience unsatisfactory recharge. [0004] The sewage treatment heat pump system that can comprehensively consider the use of the domestic sewage generated by the residential area as the cold and heat source, and can...
