Abstract

The invention relates to an energy-saving system for recycling and reusing heat energy of printing and dyeing equipment and a technological method of the energy-saving system in the technical field of environmental protection and energy-saving systems. The energy-saving system comprises the printing and dyeing equipment and a plurality of thermal storage boxes, wherein a heat exchanger is communicated with the printing and dyeing equipment; a boiler is communicated with the heat exchanger; a flash evaporator is communicated with the heat exchanger; a thermal storage air inlet and air outlet general pipe is communicated with the flash evaporator and the heat exchanger; each thermal storage box is communicated with the thermal storage air inlet and air outlet general pipe through a thermal storage air inlet branch pipe; each thermal storage box is communicated with the thermal storage air inlet and air outlet general pipe through a thermal storage air outlet branch pipe; the two ends of a thermal storage box water pipe set are communicated with the thermal storage boxes and the heat exchanger respectively. The energy-saving system for recycling and reusing the heat energy of the printing and dyeing equipment is simple in structure, efficient, energy-saving and capable of recycling and reusing a large amount of heat energy which cannot be recycled in the existing technology.

Description

technical field [0001] The invention relates to the technical field of environmental protection and energy-saving systems, in particular to an energy-saving system for recycling heat energy of printing and dyeing equipment and a process method thereof. Background technique [0002] In recent years, China's printing and dyeing industry has developed rapidly. At present, my country's printing and dyeing processing capacity ranks first in the world, and it is already a major textile printing and dyeing production country. Printing and dyeing equipment is a kind of equipment that uses a lot of steam energy. In today's fierce competition in the printing and dyeing industry, energy saving and consumption reduction have become one of the important guarantee factors for the survival and development of printing and dyeing enterprises. [0003] Such as figure 1 As shown, the existing printing and dyeing device includes: printing and dyeing equipment 1, boiler 2, cooling water tower ...
