How to clean polymerization reaction tank and stirring tank and enamel reactor?

SBR is a copolymer obtained by water emulsion polymerization of butadiene and styrene. The production process is mainly composed of preparation, polymerization, monomer recovery and post-treatment. In the production process, the materials in the reaction reactor have the characteristics of strong adhesion, easy to hang on the wall, and easy to block the tank, so the inner wall surface of the tank is required to be very smooth.

A chemical plant in Hangzhou, Zhejiang Province, with an annual output of 50,000 tons of styrene-butadiene latex project, has 4 chemical reactors that need to be cleaned during the production process. The main chemical substances to be cleaned are high molecular polymers, which are polymerized from functional monomers such as styrene, butadiene and a small amount of acrylic acid.

Keliying learned from the on-site investigation of actual working conditions through communication with customers that the 4 reactors need to be cleaned 3 to 4 times a day for maintenance. We have customized an automatic reactor cleaning system for our customers. The cleaning time for each polymerization reactor is no more than 30 minutes each time; the water produced by cleaning should stay in the tank for direct production use.

The automatic cleaning system of the polymerization reaction kettle is composed of several parts: a three-dimensional rotary tank washer, a high-pressure water washer, an automatic water supply tank device, a high-pressure rigid pipe, a high-pressure cleaning hose, a positioning device, and an automatic lifting device.

The setting degree of this system can realize one-key operation, and the degree of automation is high. The cleaning equipment in the reactor can fully clean the parts of the reactor that are difficult to clean, such as the back of the stirring shaft, the bottom, the upper head and other positions. The three-dimensional automatic rotating nozzle passes through the manhole. The telescopic positioning mechanism is sent into the designated position of the reactor, and the automatic cleaning operation is realized when the machine is turned on; the trajectory of the water jet of the medium and high pressure three-dimensional tank washer can form a complete spherical trajectory in one operation cycle. Because there is a stirring impeller and a shaft in the middle, in order to avoid the formation of dead angles during cleaning, we use two three-dimensional rotary irrigation washers to clean a tank at the same time to achieve 360-degree full coverage of the inner surface of the kettle.

The use of polymerization reactor cleaning equipment saves manpower and material resources, and is easy to achieve mechanization, automation, and high efficiency. The cleaning rate of the Keliying high-pressure water reactor inner wall cleaning system can be over 98%, and the cleaning speed is several times or even dozens of times faster than traditional methods. , and can also adjust the pressure level independently according to the scale and cleaning needs, and will not damage the smooth surface of the inner wall of the reactor. When the reactor does not need to be cleaned, the three-dimensional automatic rotating nozzle is placed in the cleaning cylinder, and the pneumatic ball valve is closed to separate the automatic cleaning device from the reactor, so that the reactor can work normally; the physical cleaning method (high-pressure water cleaning) is used to clean various pipes, Furnace, tank, water tank, reactor, heating device, etc. can be cleaned cleanly. The three-dimensional cleaning method has high cleaning efficiency, reduces the labor intensity of cleaning workers, improves the working environment of cleaning workers, and does not require personnel to enter the reactor, thereby achieving the purpose of saving energy and reducing costs.
