Abstract

The invention provides an integral cleaning method for a plate heat exchanger, and belongs to the technical field of heat exchange equipment cleaning. The integral cleaning method for the plate heat exchanger solves the problems that at present, the plate heat exchanger must be disassembled when the cleaning is performed, and the operation is cumbersome. The integral cleaning method for the plateheat exchanger comprises a plurality of steps of first-time physical cleaning, chemical cleaning, second-time physical cleaning, passivation and the like. The cleaning process can be completed withoutdisassembling the heat exchanger, the cleaning efficiency is high, the cleaning effect is good, and the cleaning effect is equivalent to the cleaning effect of a traditional disassembly cleaning method. A home-made cleaning agent is used for chemically cleaning an internal pipe of the heat exchanger, less environmental pollution is generated, and the problems such as corrosion of the interior ofthe heat exchanger during cleaning can be effectively solved. The integral cleaning method combines physical cleaning with chemical cleaning, can thoroughly clean scum, water scale and rust scale in the heat exchanger, and has a good cleaning effect, time and labor are saved, and the problem that a plate has to be disassembled when traditional plate heat exchanger cleaning is solved.

Description

technical field [0001] The invention relates to the technical field of cleaning heat exchange equipment, in particular to an overall cleaning method for plate heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are more widely used. Due to their different uses, heat exchange equipment has many types and different performances, but they can all be classified into two categories: shell-and-tube structure and plate structure. [0003] When the heat exchanger passes through water or other media during operation, various salts dissolved in it, such as bicarbonate, sulfate, chloride, s...
