Application Of Plate Heat Exchanger In Paper Industry

Pulp cooking refers to the pulping process in which papermaking raw materials and cooking liquor are put into a digester and then heated by steam to remove the non-cellulose parts of the fibrous material. The boiled black liquor in papermaking has high calorific value and good flammability, and is an important self-generated energy in the papermaking industry. TRANP's heat exchanger products can be used as a series of key energy-saving equipment in the black liquor concentration process, and are an important measure to improve energy utilization and environmental protection in paper mills.

Heat exchangers are an essential part of pulp and paper mills. With the help of heat exchangers, paper mills benefit greatly in terms of energy saving or environmental protection.

There are many processes in paper mills that can utilize heat exchangers, and now especially plate heat exchangers, which take up little space, have high heat recovery efficiency, are easy to maintain, and are low in cost.

Essentially, the paper converting line, which starts with wood pulp processing and refining and then goes into bleaching and cleaning before paper is formed, is done with the help of heat exchangers. Specifically, plate heat exchangers are used to heat the liquid used to make pulp from wood, a process that involves chemical compounds that pull apart the wood's structure, leaving behind a sticky mass that can be formed into paper after more processing. Secondary processing involves stirring or drying the pulp, a process that is also heated by plate heat exchangers. After reaching the desired color, the pulp is turned into paper by passing through a paper machine, which weaves the pulp into a thin paper web that forms a sheet. Remove all moisture during this time and use some type of blower to dry it completely.

Part of the paper machine also uses a type of heat exchanger called a waste heat recovery system, which is one of the ways a heat exchanger can save a paper mill energy, resources and money. Waste heat recovery is a waste heat recovery system. It is able to absorb heat and moisture from the room so it can be reused without further strain on the energy sources that normally supply air and water for paper processing.
