Garbage is easy to remain in the reactor that has been used for a long time. It gradually accumulates in the reactor over time, which not only affects the capacity of the reactor, but also affects the reaction. In addition to correct operation and routine maintenance, PP reactor also needs to pay attention to cleaning requirements. For example, after each operation, it is necessary to remove the residue on the kettle body and sealing surface with cleaning solution (pay attention to using cleaning solution to prevent the main material from corrosion). It is necessary to clean it frequently. It is not allowed to clean it with hard substances or things with rough surface. Now let's learn about the cleaning method of PP reactor!

PP reactor cleaning can directly improve the reaction conditions, improve the heat transfer efficiency, and reduce the energy consumption in the production process. Reactor cleaning can ensure the simplicity of the reaction, reduce the impact of impurity reaction, and reduce the probability of safety accidents; In addition, cleaning the working environment of the reactor can reduce the load of the heat exchange equipment and prolong the service life.
Mechanical cleaning
Mechanical cleaning is the most commonly used method in the cleaning of reaction kettle. The most commonly used method is high-pressure cleaning machine. Its advantages are that ordinary garbage such as powder agglomeration and accumulation has obvious effect, simple and convenient operation, low cleaning cost, and small loss. Its disadvantages are small scope of application.
In addition to the high-pressure cleaning machine, which rarely causes damage to the kettle, other mechanical cleaning methods, such as manual planing and shoveling, are relatively simple and rough. Care must be taken not to damage the pot in actual operation. In addition, because mechanical cleaning is limited by operation methods, it is particularly suitable for decomposable reactors and is limited to use in large or non-decomposable kettles.
chemical cleaning
Chemical cleaning needs to first determine the scale composition, select the corresponding cleaning solvent, and then evaluate the cleaning safety and the corrosion strength of the kettle. Chemical cleaning is a common method for reactor cleaning, which is widely used; However, the treatment of chemical waste water is difficult and the environmental pollution is serious.
In chemical cleaning, in addition to the reaction of the cleaning solvent to the dirt, other relevant parts of the reactor also corrode, so it is necessary to screen the detergent and protect the equipment and personnel.
Automatic cleaning
PP reaction kettle automatic cleaning system is a special reaction kettle cleaning device of Degaojie, which integrates the technology and application of high-pressure water flow, piping engineering, modern control system and other disciplines; The principle is to use the kinetic energy of high-pressure water flow to crush the hard scale on the inner wall of the reactor and the surface of the agitator, and completely peel it off.
PP reaction kettle automatic cleaning system sends the three-dimensional automatic rotating head to the specified position of the reaction kettle through the manhole telescopic positioning mechanism, and the three-dimensional water tank cleaning machine that connects the power supply to realize the automatic cleaning operation can form a complete spherical trajectory of the water spray trajectory in one operation cycle. There are mixing blades and shafts in the middle. In order to avoid dead corners during cleaning, two three-dimensional cleaning tanks are used to clean a tank body at the same time. The surface inside the tank can be cleaned 360 degrees in all directions.
The automatic cleaning system of PP reactor can select the appropriate pressure level according to the analysis and cleaning requirements of the scale in the reactor to keep the surface of PP reactor smooth and the scale is not easy to attach to the reactor. Realize mechanization and automation, which is several times faster than traditional methods. It only takes about 15 minutes to clean a PP reactor; The cleaning rate is above 90%, saving energy and low cost.
The above is the cleaning method of PP reactor. For more information, please feel free to contact us!
