Abstract

The invention discloses a utilizing method and system of energy-saving printing and dyeing water through circulated waste heat, which comprises the following parts: refrigerator, technical manufacturing equipment, waste water mixing pond, waste water source heat pump set, hot water pond and biochemical disposing pond, wherein the technical manufacturing equipment drains the clean water into waste water mixing pond, which heats cool water in the waste hot pond after pumping the hot water by hot water source pump set; the hot water supplying pump pumps the water into technical manufacturing equipment, which forms circulating system.

Description

technical field [0001] The invention relates to a printing and dyeing production process and a process production system, in particular to a waste heat cycle energy-saving printing and dyeing water utilization method and a corresponding process flow realization system. Background technique [0002] In the production process, printing and dyeing enterprises need to use steam heating to supply a large amount of hot water (there are mainly two temperature requirements: above 40°C and above 60°C), and at the same time produce more waste hot water with higher temperature (35~70°C ), rinsing and other processes use cold and hot water. These waste hot water can not be reused after being produced, and are directly discharged into the environment after corresponding treatment. pollute. [0003] In addition, during the printing and dyeing process, clean steam condensate water with waste heat and cooling water are produced. Many enterprises do not recycle this part of water (around 60...
