Chemical Cleaning Of Plate Heat Exchangers

  The plate heat exchanger is a new type of high-efficiency heat exchanger made of a series of metal sheets with a certain corrugated shape.Chemical Chemical cleaning of plate heat exchangerscleaning method of plate heat exchanger. For stainless steel plate heat exchangers, chemical descaling with acid detergents and cleaning powders is prohibited, especially for the entire equipment without disassembly and cleaning.This is because it is difficult to remove insufficiently dissolved scale residues during multi-slit scaling, and alkali neutralization cannot be performed sufficiently.However, for plate heat exchangers with large plate sizes and a large number of plate heat exchangers, which are not convenient to install, it is recommended to use CIP online cleaning.Because acid and corrosive cleaning agents can be injected into the interior of the plate heat exchanger, the plates can be fully infiltrated. If properly heated, the cleaning efficiency can be improved.Since the cleaning agent is only inside the plate heat exchanger, the amount of cleaning agent is small, and it will not affect the environment.However, the difficulty of CIP online cleaning is that before cleaning, the dirt inside the plate heat exchanger must be analyzed, and the cleaning agent must be matched with it. If no test matching is performed, excessively high-level cleaning agents will easily attack the heat exchanger plates.
