Description

TECHNICAL FIELD

[0002] Cloth setting is an important link in cloth processing process, and the cloth is subjected to roller flattening treatment in production to flatten the wrinkled and uneven edge cloth and improve the touch of the cloth.

[0003] A waste heat recovery tank of a textile printing and dyeing setting machine is disclosed in Chinese Patent No. CN114427799A, which comprises a heat recovery tank, an exhaust pipe and a heating pipe. A heat-conducting cleaning liquid is arranged in the heat recovery tank. The exhaust pipe is sealingly connected with the heat recovery tank. The heating pipe is arranged in the heat recovery tank. A partition is arranged in the heat recovery tank. The cleaning liquid is arranged on the upper side of the partition. The heat recovery tank is divided into two layers by the partition. The exhaust gas directly heats the heating pipe without heating other medium in the middle, thereby improving the heat conversion efficiency of the exhaust gas. The exhaust gas accumulates at the bottom of the heat recovery tank, thereby causing high air pressure at the bottom of the heat recovery tank. The high-pressure exhaust gas is absorbed by the heat-conducting cleaning liquid after entering the upper part of the heat recovery tank through the gas outlet, thereby absorbing the remaining heat and treating the harmful substances in the exhaust gas. The utilization rate of the exhaust gas heat is improved, and the pollution of the exhaust gas is reduced.

[0004] In view of the above related technology, the high-temperature exhaust gas usually carries impurities, which are easy to adhere to the surface of the heat exchange pipe, thereby affecting the heat exchange efficiency. Practical new type content
