A sewage source heat pump system for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage source heat pump system for sewage treatment, comprising a heat pump source system composed of a heat exchange terminal and a water source heat pump unit, and a water circulation composed of a water source heat pump unit, a filter mechanism and a water storage chamber The filter mechanism is a vertical casing, and a filter pipe assembly is arranged inside the casing. The filter pipe assembly is composed of a sewage inlet pipe, a flushing pipe and a connecting pipe, and the sewage inlet pipe and the flushing pipe are arranged parallel to the casing The internal sewage inlet pipeline and the flushing pipeline are connected by connecting pipelines, and the invention solves the problem that the maintenance cost of the filter shell in the heat pump source treatment system is relatively high. The filter shell in the heat pump source treatment system and the internal structure of the shell It is proposed to reduce the cost of maintaining the equipment, and at the same time, the sewage can be reused, saving energy and protecting the environment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage source heat pump system for sewage treatment. Background technique [0002] The sewage source heat pump has gradually become the new favorite of the central air-conditioning industry due to its advantages of low initial investment and operation cost, significant energy saving and environmental protection benefits, simple system, stable and reliable operation. [0003] Chinese patent (CN102205189A) discloses a sewage treatment device. A shell is divided into a filter cavity and a flushing cavity from top to bottom. There are sewage water inlets and filtered water outlets on both sides of the filter cavity, and there are return water ports and sewage outlets on both sides of the flushing cavity. The sewage water inlet and the filtered water outlet are separated by a filter screen; a bowl sleeve is fixed on the inner wall of the casing, a piston rod is pierced thro...

Problems solved by technology

[0004] In this technical solution, the design of the scraper is mainly used to scrub the filter screen in the filter chamber, and at the same time, the transmission design similar to the piston rod is used to achieve the purpose of scraping impurities such as sludge. In the actual application process, We found that the components such as the piston rod, telescopic protective sleeve, rotor plate, and bristles are all built in the housing, and they are severely worn during the long-term transmission process, and it is difficult to take them out for replacement in time. It takes a lot of effort and time to renovate, and the maintenance cost of the filter shell is relatively high
