Thermal energy recycling heat exchanger

Abstract

The invention discloses a thermal energy recycling heat exchanger. The thermal energy recycling heat exchanger comprises a waste heat water tank body with at least one side wall provided with an opening sealed with an elastic film. The thermal energy recycling heat exchanger further comprises a drive device used for driving the elastic film to repeatedly deform. The provided thermal energy recycling heat exchanger is high in heat exchanging speed and capable of solving the problem that due to the fact that impurities are attached to a heat exchanging device, the heat exchanging efficiency is affected.

Description

technical field [0001] The invention relates to the technical field of heat energy recovery, in particular to a heat energy recovery heat exchanger. Background technique [0002] During the printing and dyeing process, most fabrics require high-temperature and high-pressure dyeing. The dyeing temperature is between 100-135°C. After high-temperature dyeing of fabrics, some high-temperature wastewater with a temperature above 95°C will be formed. In order to reduce pollution, the factory will After the high-temperature wastewater is purified and treated, it can be recycled. [0003] Before purifying the high-temperature wastewater, it is necessary to cool down the high-temperature wastewater. There is a heat recovery heat exchanger in the prior art, which can transfer the heat energy in the high-temperature wastewater to clean cold water, so as to realize the recycling of heat energy. At the same time, It can quickly cool down the high-temperature wastewater to facilitate the...

AI Technical Summary

Problems solved by technology

[0006] However, the heat recovery heat exchanger in the prior art has a slow heat transfer rate and poor heat transfer effect

In addition, since waste water usually contains more impurities, it is easy to adhere to the heat exchange device 2, and the impurities have the effect of heat insulation, which leads to poor heat exchange effect

[0007] Therefore, how to increase the heat exchange speed of the heat recovery heat exchanger and prevent impurities from adhering to the heat exchange device, resulting in poor heat exchange effect, has become an important technical problem to be solved by those skilled in the art.
