Combined type anti-corrosion wide-runner sewage heat exchanger

Abstract

The invention discloses a combined type anti-corrosion wide-runner sewage heat exchanger. A tube end base is arranged in a housing, and is a multi-layer combined type; the tube end base and a tube end base fixed mount are fixed as a whole by virtue of a bolt; the tube end base is provided with a fixing hole matched with a heat exchange tube in appearance; a heat exchange tube is arranged in the tube end base; the tube end of the heat exchange tube is fixed to the tube end base fixing hole; and baffling ribs are arranged between the housings, at the two ends in an axial direction of the heat exchange tube, and the tube end base at intervals. The combined type anti-corrosion wide-runner sewage heat exchanger has the advantages that: quantity of units of the tube end base can be freely increased or reduced by adopting the combined type tube end base, so that the size of the area of the heat exchanger is regulated. The combined type anti-corrosion wide-runner sewage heat exchanger is convenient to repair and maintain, so that the defect that only destructive cutting type maintaining or integral scrapping can be carried out due to local blockage and leakage of the integral welding structural-form sewage heat exchanger is avoided; and primary and secondary water adopts a reverse crossed heat exchange mode, so that the heat exchange efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat exchanger. Background technique [0002] Sewage heat exchanger is the front-end product in the sewage source heat pump system. It is mainly used to extract the heat dispersed in urban raw sewage, industrial wastewater and other sewage in winter, and transfer it to the heat pump unit through intermediary water exchange, and the heat pump unit is lifted to provide heating for buildings. ; In summer, the heat inside the building is transferred to the sewage to cool the building. [0003] The use of sewage source heat pumps to realize the recycling of urban waste heat and turn waste into treasure is a new type of renewable and clean energy utilization technology, which meets the requirements of sustainable development, building a resource-saving and environment-friendly society. It has far-reaching significance in expanding the scope of urban sewage utilization and expa...

AI Technical Summary

Problems solved by technology

", the patent application adopts the overall structure, and still does not solve the defects of poor applicability, poor corrosion resistance, easy clogging, and short service life.

It is also not convenient for daily repair and maintenance. Due to the adoption of the integral welded structure, if there is a partial blockage or leakage in the future, only cutting repairs can be performed or the equipment will be scrapped as a whole.
