Abstract

The invention provides a high-temperature waste water waste heat recycling device, and relates to the field of waste heat recycling. The high-temperature waste water waste heat recycling device comprises a base, a heat exchange barrel, two sealing covers and a self-cleaning heat exchange mechanism used for heat exchange, the heat exchange barrel is fixedly connected to the base, the two ends of the heat exchange barrel are each in threaded connection with one sealing cover, the surface of the sealing cover on the left side is sleeved with a waste water outlet pipe, the surface of the sealing cover on the right side is sleeved with a waste water inlet pipe, and the left side of the bottom of the heat exchange barrel is sleeved with a clear water inlet pipe. According to the high-temperature waste water waste heat recycling device, a special structure capable of avoiding dirt adhesion, enhancing the heat exchange effect and rapidly cleaning is designed according to the problems that dirt is prone to being accumulated and difficult to remove in an existing heat exchange device, and therefore the problems that impurities and dye precipitates in printing and dyeing waste water are prone to being adhered to a common heat exchange device, the heat exchange efficiency of a pipeline of the heat exchange device is directly influenced, and the cleaning work is frequent and difficult are effectively solved.

Description

technical field [0001] The invention relates to the technical field of waste heat utilization, in particular to a waste heat recovery and utilization device for high-temperature waste water. Background technique [0002] In the process of textile printing and dyeing, a large amount of high-temperature printing and dyeing wastewater will be produced. The heat in these high-temperature wastewater can be recycled, but the printing and dyeing wastewater contains a large amount of fluff impurities and some dye precipitates. These impurities and precipitates are easy to exchange heat. Deposits on the inner wall of the pipe will form thick knots on the pipe wall after long-term use. These knots will not only affect the flow of water, prolong the heat exchange time, but also increase the wall thickness. Therefore, it is necessary to clean the inside of the heat exchange tube frequently, but the inside of the tube is narrow and it is very inconvenient to clean. The general heat excha...
