Problems solved by technology

[0003] When the existing frame-type plate heat exchanger recycles the waste heat in the textile wastewater, the treated textile wastewater and cold water are injected into the plate heat exchanger, and the waste heat in the textile wastewater is used to heat the cold water. The plates of the plate heat exchanger are sealed by large-area sealing gaskets. Since the textile waste water and cold water entering the plate heat exchanger flow too fast, the sealing gaskets will be continuously impacted. It will deform the sealing gasket and cause the plate heat exchanger to leak. Due to the high temperature of the textile wastewater, the minerals in the textile wastewater are easy to adhere to the plate wall of the plate heat exchanger, thereby increasing the thickness of the plate heat exchanger. , increasing the heat exchange distance of cold and hot water, reducing the heat conversion efficiency of the plate heat exchanger, and causing inconvenience to the waste heat recovery and reuse of textile wastewater

Abstract

The invention relates to a heat exchanger, in particular to an environment-friendly Tencel solvent purification treatment device with a self-cleaning plate heat exchanger. The technical problem of the present invention is to provide an environmentally friendly Tencel solvent purification treatment device with a self-cleaning plate heat exchanger that prevents the deformation of the sealing gasket and improves the heat conversion efficiency. The technical embodiment of the present invention is: an environment-friendly Tencel solvent purification treatment device with a self-cleaning plate heat exchanger, comprising a conveying pipe and a heat exchange mechanism; the conveying pipe is connected with a heat exchange mechanism. The invention cleans the scale adhering to the board wall by cleaning the components, slows down the flow of textile waste water, avoids deformation and leakage caused by the continuous impact of the sealing gasket, and at the same time avoids the increase of the thickness of the board wall due to the accumulation of scale, and realizes the improvement of the board replacement. Heat transfer efficiency of the heater.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to an environment-friendly Tencel solvent purification treatment device with a self-cleaning plate heat exchanger. Background technique [0002] The oxide solvent in the Tencel production process can be recycled in the manufacturing process. In order to save energy and protect the environment, it is necessary to purify the oxide solvent to achieve the purpose of reuse; The textile wastewater contains a lot of waste heat, and the preheated textile wastewater will undergo heat conversion through a plate heat exchanger, and the waste heat in the textile wastewater will be recycled and reused to reduce heat loss. [0003] When the existing frame-type plate heat exchanger recycles and reuses the waste heat in textile wastewater, both the treated textile waste water and cold water are injected into the plate heat exchanger, and the cold water is heated by using the waste heat in the textile wastewater,...
