There are obvious design defects in ordinary heat exchangers, and blockage and cleaning of heat exchangers have become the most troublesome problems in the use of sewage source heat pump units.
However, some sewage source heat pump manufacturers have made some improvements on this basis. For example, a waste water filtering device-"anti-blocking machine" has been added to the front end of the sewage source heat pump, but after filtering the waste water, it is still necessary to exchange heat energy [there will be blockage after filtering, you know], which is far from the innovation of centrifugal sewage heat exchanger.
Centrifugal sewage heat exchanger adopts many new materials and surface treatment technologies to solve the problems of corrosion prevention and scaling; In design, the centrifugal sewage and wastewater heat exchanger changed the route of selecting filters in wastewater utilization, broke the bondage of inertial thinking, and let wastewater directly enter the heat exchanger, which is to dredge rather than filter, so that sewage and sundries can smoothly spiral down the heat exchanger, and the middle water can flow upstream. By using the movement law of fluid and the principle of zonal heat exchange, the blocking problem of sewage and wastewater application is solved and the heat exchange efficiency is improved. The centrifugal sewage heat exchanger was awarded the utility model patent by the State Patent Office on March 7th, 20 12.
