Removable Plate Heat Exchanger: The Removable plate heat exchanger is a new type of high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the various plates, and heat is exchanged through the halves. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more. This product is suitable for chemical, machinery, food, beverage, medicine, residential heating, hot water supply, air conditioning and other departments.

Application field: Crude oil, natural gas purification and chemical products; chemical industry; pharmaceutical and specific chemicals; injection control systems; HVAC, district heating, thermal power plants; food processing; cooling tower heat recovery Process requirements Pickling temperature: Raising the pickling temperature is conducive to improving the descaling effect. If the temperature is too high, it will aggravate the corrosion of the pickling solution to the heat exchanger plates. Through repeated tests, it is found that the pickling temperature should be controlled at 60. 2) Concentration of pickling solution: According to repeated tests, the pickling solution should be prepared according to the concentration of formic acid 81.0%, water 17.0%, buffer 1.2%, and surfactant 0.8%, and the cleaning effect is excellent. 3) Pickling method and time: The pickling method should be carried out by a combination of static soaking and dynamic circulation. The pickling time is static soaking for 2h first, and then dynamic circulation for 3~4h. During the pickling process, samples should be taken frequently to test the pickling concentration. When the difference between the two adjacent test concentrations is less than 0.2%, the pickling reaction can be considered to be over. 4) Passivation treatment: After pickling, most of the scale and metal oxides on the surface of the plate heat exchanger will be dissolved and fallen off, exposing new metal, which is very easy to corrode. The sheet is passivated.
