Abstract

The utility model relates to a medium-pressure high-temperature steam heating heat exchanger, comprising a plurality of heat conduction pipe connection heat exchange pieces; the heat conduction pipe connection heat exchange pieces are of metal seamless heat conduction pipe connection heat exchange pieces; radiating pieces wrap the outer parts of the heat conduction pipe connection heat exchange pieces; heat conduction pipe connection plates are arranged at two ends of the heat conduction pipe connection heat exchange pieces; seal ends are arranged at the outer parts of the heat conduction pipe connection plates; the heat exchanger is also provided with an inlet flange, an outlet flange and a water emptying outlet, which are all arranged on the seal ends. The heat exchanger can bear the weight of about 30Kg, the maximal pressure of 36Kg and the highest temperature of 320 DEG C and can meet the medium-pressure high-temperature needs in the industrial production. Steam heating is adopted, and industrial waste heat steam can be adopted as a heat exchange source to realize the step utilization of waste heat, thus making great contribution to use of new resources, effectively avoiding haze generated in the burning of a boiler and eliminating the haze source. The heat exchanger accords with the topic of environment protection, and is low in price, low in cost and simple in operation.

Description

technical field

[0001] The invention relates to a heat exchanger, in particular to a medium-pressure high-temperature steam heating heat exchanger, which is applied in the fields of textile, printing and dyeing, rubber, tanning, wood processing, grain, oil and food processing, painting and baking paint, etc. Background technique

[0002] Radiators are widely used in various fields of industrial production. Such as textile, printing and dyeing, rubber, tanning, wood processing, grain and oil food processing, painting and baking paint and other industries have been widely used, and have achieved satisfactory results. At present, the heat exchangers on the market are mainly liquid heating, and some enterprises use flue gas as the heat exchange source, but the flue gas needs to be produced by burning coal in the boiler, which is the source of smog, which is contrary to the current theme of environmental protection. Some enterprises propose to use natural gas as a raw material. ...
