Abstract

Disclosed is a printing and dyeing drying waste-heat utilization device. The printing and dyeing drying waste-heat utilization device comprises a high-temperature dye liquor drainage tube, a heat exchanger and a warm water preparation delivery line. A drying setting machine of a recovery device for heat in waste dyeing liquor is in use. Cloth is pre-dried before entering a setting machine drying room and therefore the load of the setting machine drying room is reduced, so that the cloth speed of the setting machine is increased, and the setting efficiency of the setting machine is effectively improved; at the same time, the pre-dried cloth brings heat into the setting machine drying room to enable the temperature increase rate of the first section of the setting machine drying room to drastically increase, and accordingly overall heat consumption of the setting machine is reduced. According to the printing and dyeing drying waste-heat utilization device, compared with a traditional setting machine, the setting machine can save heat by 10%-15%.

Description

technical field [0001] The invention relates to a printing and dyeing drying waste heat utilization device, which belongs to the technical field of textile printing and dyeing. Background technique [0002] my country is a major printing and dyeing country in the world. The national output of printed and dyed cloth accounts for more than 1 / 3 of the world's total output. The printing and dyeing industry has made significant contributions to my country's national economic development, fiscal revenue, foreign exchange earnings from exports and employment. However, with the continuous development of the printing and dyeing industry, problems such as high production energy consumption and large exhaust gas emissions have also arisen. According to statistics, compared with developed countries, the energy consumption per unit output value of my country's printing and dyeing enterprises is about 2.3 times that of developed countries, while the profit per unit of printing and dyeing ...
