Problems solved by technology

[0003] The existing polypropylene reactor uses circulating water to enter the interlayer of the reactor for temperature control. Long-term use of circulating water in the interlayer will cause serious fouling inside the jacket, resulting in a decrease in the heat transfer coefficient, which cannot meet the needs of temperature control.

Abstract

The invention discloses a polypropylene polyreactor. The polypropylene polyreactor comprises a polyreactor body and a stirring device; the polyreactor body is composed of a first part, a second part and a third part from top to bottom, wherein the first part and the third part are each in a hemispheroid shape, the second part is in a cylinder shape, and a first opening is formed in the inner side wall of the upper portion of the second part in the peripheral direction; the stirring device comprises a rotating shaft, multiple stirring blades, at least one cross rod, two baffles and multiple brush rods; one end of each cross rod is fixedly connected with the rotating shaft, and the other end of each cross rod penetrates through the first opening; one baffle is arranged in a hollow part between the inner side wall and the outer side wall of the second part, and the other baffle is arranged in the second part; the brush rods are arranged in the hollow part between the inner side wall and the outer side wall of the second part. According to the polypropylene polyreactor, in the polyreaction process, scale on the inner walls and outer walls of the second part and the third part is scraped away continuously, the polyreactor can keep a certain heat transfer coefficient, and temperature control requirements are met.

Description

technical field [0001] The invention relates to a reaction kettle. More specifically, the present invention relates to a polypropylene polymerization reactor. Background technique [0002] The polypropylene reactor can fully stir the chemical substances, and the reaction time, stirring intensity and temperature during stirring have a great influence on the polymerization reaction. [0003] The existing polypropylene reactor uses circulating water to enter the interlayer of the reactor for temperature control. Long-term use of circulating water in the interlayer will cause serious fouling inside the jacket, resulting in a decrease in the heat transfer coefficient, which cannot meet the needs of temperature control. Contents of the invention [0004] The purpose of the present invention is to provide a polypropylene polymerization reactor, which can continuously scrape off the scale on the inner and outer walls of the second part and the third part during the polymerization...
