Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to an H-shaped fin-tube heat exchanger for recovering waste heat from a high-temperature cloth setting machine. Background Art

[0002] my country is a major textile producer. Exhaust emissions from stentering machines in the printing and dyeing industry waste significant energy and pollute the environment, making waste heat recovery and purification from these machines crucial. The printing and dyeing industry consumes approximately 1.5 tons of coal to process one ton of knitted fabric, of which stentering machines account for approximately 40%. However, the heat energy consumed by the fabric during operation only accounts for 29%, while the machine itself consumes 10%, while the heat emitted by exhaust gases accounts for 61%. The exhaust gas emitted from stentering machines processing chemical fiber products has an emission temperature of 160-170°C. The waste heat recovery process within these machines contains a significant amount of heat energy. Failure to recover this heat would result in energy loss and waste, increasing production costs for the company.

[0003] H-type finned tube is an enhanced heat exchange element arranged at the tail end of the system flue for exhaust gas waste heat recovery. Because the fins are symmetrical and arranged in a rectangular shape, it looks like the letter H when viewed from the side, so it is called H-type finned tube.

[0004] Currently, the existing H-type fin-tube heat exchanger can make the heat exchange tubes have good corrosion resistance and prevent the fins from injuring employees. However, because the fins dissipate heat through the natural flow of air to cool down, and the fin spacing is too small, the heat is easily gathered together, resulting in poor heat exchange effect. In addition, the existing heat exchange tubes cannot ensure that the fins are in the same direction when docking. Utility Model Content
