Description

Heat exchanger

This creation is about a heat exchanger, especially one that has two separate heating lines.

At present, the common heat exchangers are connected to a cold water pipe and a hot water pipe. The cold water pipe and the hot water pipe are connected to each other. One end of the cold water pipe is connected with a water source to input the cold water to be heated, and the cold water enters the heat exchanger for heat. After the exchange, hot water is output from the hot water line for use.

By using the above principle of heat exchange, it can be applied to the dyeing operation of the dyeing machine. Wherein, when a cloth is wound around the mesh wheel disposed inside the outer casing, the pressure of the pump can be used to accelerate the dyeing liquid heated by the heat exchanger to the outer diameter of the mesh wheel to accelerate the outer spraying. Dyeing operation. However, the dyeing liquid is formed by mixing the liquid medicine and water. In the dyeing process of the cloth, the temperature of the dyeing liquid must be controlled according to the characteristics of different fabrics to achieve the best dyeing quality.

In actual use, the heat exchanger of the dyeing machine mainly uses steam for heat exchange, so that the temperature of the dye liquor in the pipeline rises, and in this way, the temperature of the dye liquor can only reach about 140 ° C. Left and right, for the fiber cloth that needs higher temperature to achieve better dyeing quality, the above heat exchange method cannot meet the demand; in addition, the single heat exchange method has a higher risk of failure and lacks flexibility in use.
