Printing and dyeing heat exchange device

Abstract

The invention discloses a printing and dying heat exchange device. The printing and dying heat exchange device comprises a first heat exchange mechanism and a second heat exchange mechanism which communicate with each other. The first heat exchange mechanism comprises a first heat exchange device body, a second heat exchange device body, a third heat exchange device body and a fourth heat exchangedevice body. A partition plate for partitioning the space in a first barrel is arranged in the first barrel. A plurality of inserted-connection portions matched with the partition plate are arrangedon the inner wall of the first barrel. By arranging the multiple inserted-connection portions in the first barrel, the partition plate can be detached relative to the first barrel, the partition platecan further be replaced with partition plates of different structures so that the sizes of a waste water channel and a clean water channel can be adjusted properly to adapt to heat exchange treatmentof waste water of different heat degrees, the application range is wide, and the heat energy utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing, in particular to a printing and dyeing heat exchange device. Background technique [0002] After the fabric is dyed, the dyeing wastewater in the dye vat needs to be discharged to the outside, and clean water is injected into the dye vat to clean the dye vat and replenish the water in the dye vat. In the traditional dye vat, the temperature between the clean water and the wastewater is usually exchanged through a heat exchange device during the water exchange process, and then the heat energy is reused. The traditional structure is to divide the heat exchange channel into a waste water channel and a clean water channel through a partition plate, and realize heat exchange through the reverse circulation of the two. However, in this structure, the separator is fixed in the channel, the channel size of the waste water channel and the clean water channel cannot be adjusted, and the use range i...

Problems solved by technology

However, under this structure, the partition is fixed in the channel, and the channel size of the waste water channel and the clean water channel cannot be adjusted, and the scope of use is small. When the temperature of the waste water is too high, it is often difficult to completely absorb the heat of the waste water.
