Application Of Plate Heat Exchanger In Paper Industry

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

Heat exchangers are an important 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 make use of heat exchangers, especially plate heat exchangers, which take up small space, have high heat recovery efficiency, are easy to maintain and have low cost.

Essentially, the paper processing line, which starts with wood pulp processing and refining and then goes into bleaching and cleaning before the paper is formed, is all 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 structure, leaving behind a sticky substance that can form paper after more processing. Secondary processing involves stirring or drying the pulp, a process that is also heated by a Plate Heat Exchanger. After reaching the desired color, the pulp is turned into paper by a paper machine, which weaves the pulp into thin sheets that form paper pages. During this time remove all moisture and dry it completely using some type of blower.

Part of the paper machine also uses a heat exchanger called a waste heat recovery system, which is one of the ways that heat exchangers are able to save energy, resources and money for paper mills. Waste heat recovery is a waste heat recovery system. It is able to absorb heat and moisture in the room so that it can be reused without putting more pressure on the energy sources that normally provide air and water for paper processing.
