Problem background:

Most of the cotton long yarn printing and dyeing factories are directly summing up the sewage from 50℃ - 80℃ in the dyeing tank to the cesspool, and discharging it directly to the sewage treatment plant through the pipeline for centralized treatment. And the dyeing tank should constantly add room temperature water and steam to raise the water temperature to meet the production process requirements, and the 50 ℃ - 80 ℃ sewage contains a lot of heat energy is discharged in vain.


Design a waste heat recovery device to recover part of the heat from the sewage and heat the water to enter the dyeing tank so as to reduce the steam consumption of heating water.
