It has a wide range of uses and plays an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. It is most commonly used in the chemical industry and petrochemical industry. The pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels. Pressure vessels are mainly used in the chemical and petrochemical fields for heat transfer, mass transfer, reaction and other process processes, as well as for the storage and transportation of pressurized gases or liquefied gases. They are also widely used in other industrial and civil fields, such as air compressors.
[0003] When the pressure vessel is in use, the staff needs to maintain and clean the pressure vessel. However, since the bottle mouth of the pressure vessel is relatively narrow and the bottle body is relatively wide and fat, when cleaning the inner wall of the pressure vessel, it is inconvenient to brush the inner wall after the cleaning brush is inserted into the bottle. As a result, the staff needs to clean the inner wall of the pressure vessel repeatedly, which wastes a lot of time and increases the labor intensity of the staff, resulting in low efficiency in the use of the pressure vessel. Therefore, a pressure vessel inner wall cleaning device is proposed. Utility Model Content
