As one of the four great inventions in ancient China, papermaking has played a great role in promoting the development of civilization and social progress. After nearly two thousand years of development, modern papermaking technology has long been different from the papermaking technology just born, both in terms of production technology and the quality of the paper produced. Humans have used a variety of modern technology products in the papermaking process, and plate heat exchangers are one of them.Plate heat exchanger is a new type of high-efficiency heat exchanger which is formed by stacking a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates to exchange heat through the plates. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, and long service life. So what are the specific steps of the application of plate heat exchangers in the paper industry?
1. Plate heat exchanger is used for pulp processing. (1) In the steam cycle (2) In the acid preparation process
(3) In the boiling process (4) In the heating process of the lye, such as in the bleaching process of the exhaust gas desulfurization plant.
2. The plate heat exchanger is used in the papermaking process. (1) Cooling of the machine drum in the papermaking process (2) Connection port of the glue heater (3) Preheating water for waste paper treatment (4) For paper concentration (5) For sewage treatment
