Abstract

The invention relates to a smooth heat exchanger of sewage or a surface water source heat pump and a system thereof, in particular to a heat exchanger for extracting heat or cold from the sewage or surface water by using a heat pump technology and a system thereof, belonging to the technical field of energies. The invention aims to solve the key problems of suspended matter blocking, and complex technical process, great floor area and the like which are caused by trying to realize blocking prevention in the prior art. The heat exchanger is composed of a large-diameter pipe, a pipe sheet, a shell, inner and outer partitions, closing plates, sewage or surface water inlet and outlet, clear water inlet and outlet and the like. The system is composed of the heat exchanger, a heat pump set, a water pump, connecting pipelines and the like. The sewage or the surface water can smoothly flow in the large-diameter pipe, the clear water and the sewage form countercurrent flow in the shell, and the heat pump set extracts heat from the clear water. The invention is suitable for a sewage or surface water source heat pump indirect system, and the front end does not need a filter screen or an anti-blocking device, thereby realizing continuous heat exchange and heat extraction without blocking. The invention has the advantages of simplified system and technical process, high heat exchange efficiency and small floor area.

Description

technical field [0001] The invention relates to a heat exchange device and system for extracting heat or cold from sewage or surface water by using heat pump technology, and belongs to the field of energy technology. Background technique [0002] The use of heat pump technology to extract low-level thermal energy from sewage or surface water for building heating and air conditioning, that is, sewage or surface water source heat pump heating and air conditioning systems, has huge energy-saving potential, and its energy-saving rate can reach more than 45%. According to the calculation and calculation of the existing sewage discharge in our country, the development and utilization of low-level thermal energy of sewage (according to the temperature drop of 4-5°C) can provide heating and air conditioning for 20% of urban buildings. one of the ways. [0003] Sewage source or surface water source is a kind of water source. Compared with groundwater, its main feature is that the co...
