The plate heat exchanger is a new efficient and compact heat exchanger that has developed and extensively used in recent decades. It consists of multiple parallel corrugated-surface thin metal sheets that overlap and are then fixed by lamp plates and bolts. The cold working fluid and the hot working fluid flow through the narrow and winding passage made of two neighboring plates alternately and realize cold and heat exchange through the plates separating the two working fluids.
n the paper processing and manufacturing process, starting from wood pulp processing and refining, and then in the paper bleaching and cleaning, are completed with the help of the plate heat exchanger in the paper industry. Plate heat exchangers are used to heat the liquid that makes the pulp, a process that involves chemical compounds that pull apart the wood structure, leaving behind a sticky substance that can be processed more to form paper. Secondary processing involves stirring or drying the pulp, which also requires heat transfer equipment. The waste heat generated by the papermaking process can also be recycled through heat exchanger, which can be recycled and utilized.

The plate materials and the gasket materials mainly depend on the corrosive properties and temperatures of the cold exchange medium and the heat exchange medium. The plate heat exchanger's plate materials and corresponding applicable places are given in Table 1 and its gasket materials and corresponding applicable places in Table 2 for your reference.
