Tube and tube heat exchanger is a new type of self-cleaning heat exchange device with mature technology. What should you do if you want to clean the tube and tube heat exchanger? What is a good way? Let’s take a look with everyone below.
Cleaning the tube and tube heat exchanger can improve heat exchange efficiency, save energy, extend the service life of heat exchange equipment, improve production efficiency and product quality, and reduce economic losses. It is mainly composed of heat exchange tube bundles and shells, and has various forms such as fixed tube plate type, U-shaped tube type and floating head type.
Tube and tube heat exchangers have the advantages of low cost, wide range of material selection, simple structure, large processing capacity, and wide temperature and pressure adaptability range.
In the industrial production process, sometimes accidents caused by improper operation can cause scaling and blockage of individual equipment or local pipelines, affecting the normal operation of production. In this case, the main thing is to quickly remove the dirt to ensure the normal operation of the production equipment, restore normal production status, and restore the production efficiency of the device. For example, scaling of chemical equipment causes the heat transfer coefficient of heat exchanger and other equipment to decrease, the pipeline circulation area decreases or the circulation resistance increases, energy and material consumption increases, and production efficiency drops significantly. At this time, the production equipment is restored through cleaning and descaling. production efficiency.
Due to various reasons, a large amount of dirt will be produced in heat exchange equipment and pipelines, such as coking, corrosion products, polymers, oil scale, scale, sediments, fungi, algae , slime, etc. However, the dirt generated during the work process will cause equipment and pipelines to fail, and the factory system will experience adverse situations such as reduced output and increased energy and material consumption. When the dirt is particularly corrosive, the process will be interrupted and the factory system will be forced to stop production, directly causing various economic losses and even causing vicious production accidents. With the development of science, it is almost impossible to completely avoid the generation of dirt. Therefore, the cleaning of heat exchangers and other equipment has become an indispensable and important link in the production of petroleum, chemical, electric power, metallurgy and other industries.
Compared with traditional manual, mechanical and chemical cleaning, high-pressure water jet cleaning of tube and tube heat exchangers has the advantages of low cleaning cost, good cleaning quality, fast cleaning speed, no pollution to the environment, and no corrosion of equipment.
The above is an introduction to the cleaning of tube and tube heat exchangers. I hope it will be helpful to everyone.
