Application of plate heat exchanger in paper industry

Views:　Date:2020-04-28
The cooking process of pulp in a paper mill refers to a pulping process in which raw materials and cooking liquid are placed in a cooking pot, and then the non-fiber part of the raw materials is removed by steam heating. Because the black liquor produced in the cooking process has two characteristics of high calorific value and flammability, it is usually used as a self-generated energy in paper mills. The plate heat exchanger made by Prepler can be used as a key device in the process of concentrating black liquid to improve energy use.
In the paper mill, there are many processes that can use heat exchange equipment, especially the plate heat exchanger we produce, because it has the characteristics of less space occupation, high heat recovery utilization rate, easy maintenance and repair, and low cost. .
In the paper production line, we can see the heat exchanger from the beginning of the pulping process, the subsequent refining process, and the final cleaning and bleaching process. In the pulping process, a plate heat exchanger can be used to heat the liquid used to make pulp from the raw materials. In the secondary processing, the process of stirring and drying the manufactured pulp is also completed by the heat exchanger.
A heat exchanger is also used in the waste heat recovery system of the paper mill, which absorbs excess heat and moisture for reuse, so that it can reduce the supply of air and water resources for paper processing from the outside, thereby saving energy, reducing costs, and improving production The purpose of efficiency.
