Problems solved by technology
[0003] Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. The plate heat exchanger is an ideal equipment for liquid-liquid heat exchange. It has high heat exchange efficiency, small heat loss, compact and light structure, and occupies an area Small area, wide range of applications, long service life, etc.; scaling, fouling, etc. are prone to occur during use, and scaling results in a significant reduction in heat exchange efficiency. Manual disassembly is required when using descaling agents or professional descaling methods Cleaning, disassembly and cleaning take a long time and low efficiency, which affects the normal operation of the system, and the cost of manual disassembly and maintenance is high, resulting in high cost of operation and maintenance and descaling, resulting in general use effect. Therefore, a descaling method for plate heat exchangers is proposed method to solve the above problems

The invention discloses a method used for descaling of a plate heat exchanger, and relates to the technical field of heat exchanger application. A heat exchanger is included, a primary side and a secondary side are arranged on the heat exchanger and are two independent circulation processes, and quick connectors are additionally arranged on water inlet and outlet pipelines of the primary side andthe secondary side. The quick connectors are connected with an acid pickling cleaning liquid device to achieve cleaning. The heat exchanger comprises a secondary side outlet pipeline, a secondary sidecleaning liquid inlet, a secondary side inlet pipeline, a secondary side cleaning liquid outlet, a primary side outlet pipeline, a primary side cleaning liquid inlet, a primary side inlet pipeline and a primary side cleaning liquid outlet. According to the method used for descaling of the plate heat exchanger, a heat exchange device adopts the quick connectors additionally arranged at connectors,disassembly-free quick cleaning is adopted, a solution which does not damage the heat exchanger is selected as cleaning liquid, dirt in the heat exchanger is cleaned away through mechanical pressurized circulation, the heat exchange efficiency is improved, operation is convenient and quick, quick connecting can be achieved during field mounting, and later maintenance is convenient.
Description
technical field [0001] The invention relates to the technical field of heat exchanger application, in particular to a method for descaling a plate heat exchanger. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. A thin rectangular channel is formed between the various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. In the case of pressure loss, its heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, and the floor area is one-third of that of the tube heat exchanger, and the heat recovery rate can be as high as 90%. The plate heat exchanger is The current common heat exchange dev...
