Introduction of heat exchange equipment:
Heat exchange equipment is an indispensable equipment for realizing heat exchange and transfer in chemical production process. There are often some corrosive and oxidizing materials in heat exchange. Therefore, the materials used to manufacture heat exchange equipment are required to have strong corrosion resistance. It can be made of non-metallic materials such as graphite, ceramics, glass, and metal materials such as stainless steel, titanium, tantalum, and zirconium. However, those made of graphite, ceramics, glass and other materials have disadvantages such as brittleness, large volume and poor thermal conductivity. , and produce intergranular corrosion.
The significance of thermal equipment cleaning: (1) The heat exchange equipment cleaning improves the heat exchange efficiency and saves energy. After the heat exchanger and boiler heat transfer equipment is fouled, the heat transfer efficiency of the equipment will be reduced, resulting in a large amount of energy waste. The thermal conductivity of the scale layer is very small compared to carbon, and the scale causes considerable heat transfer loss. During the normal production process, the thicker the scale, the greater the energy consumption. Therefore, cleaning and descaling can improve the heat exchange efficiency of the equipment. ,Energy saving.
(2) Cleaning the heat exchange equipment to prolong the service life of the equipment. For the heat exchange equipment, the thermal conductivity is reduced due to scaling, and the local overheating of the tube wall temperature may cause accidents such as bursting. For example, the relationship between boiler scale thickness and tube wall temperature. Therefore, cleaning the heat exchange equipment can reduce the temperature of the pipe wall, effectively avoid pipe burst accidents, and prolong the service life of the equipment. Heat exchange equipment cleaning technology is very critical.
