Description

Technical Field

[0001] The utility model relates to the technical field of heating network, in particular to a high-efficiency heating network heating device. Background Art

[0002] The heating network is a system facility that transports heat energy to heat users through pipes and heat carriers (working media, usually water or water vapor); and the heating device of the heating network, namely the heating network heater, is one of the key equipment in the operation of the heating network. It mostly uses steam and other gases to heat the circulating water in the supply system to meet the needs of heating users.

[0003] Prior art, such as the utility model with publication number CN220729028U, discloses a heat network heater. The patent adopts a heater assembly and an air push expansion assembly. A bottom support frame is provided at one end of the heater assembly. A two-way air supply assembly is provided on the top of the bottom support frame. The fixed pipe is inserted into the inlet end of the tube bundle heat exchanger and pushed inward. The air supply pump body can inject gas into the inner push air pipe at a fixed time. The auxiliary impact force is used to drive the descaling pipe to move inside the tube bundle heat exchanger, so as to facilitate pushing the descaling pipe to a certain position inward, and then the air supply pump body is used to reel the pipe. Gas is injected into the pipe fittings and the scale-cleaning pipe fittings to drive the scale-cleaning scrapers to expand outward until the scale-cleaning scrapers abut against the inside of the tube bundle heat exchanger, and then the scale-cleaning pipe fittings are pulled back and forth to clean the scale deposited in the tube bundle heat exchanger, thereby completing the cleaning of the scale in the tube bundle heat exchanger and solving the problem that the current heat network heater uses boiler steam to exchange heat with water. After the heat network heater is used for a long time, a large amount of scale is easily attached to the internal tube bundle. The traditional solution is to add filtering equipment at the water inlet end to reduce the generation of scale, but it cannot completely prevent the generation of scale in the heater tube bundle.
