A kind of efficient cleaning system and cleaning method of polymerization reactor

Abstract

The invention discloses a high-efficiency cleaning system and a cleaning method for a polymerization reactor. The connecting mechanism comprises a sliding pipe and a symmetrically arranged connecting pipe. The spring tubes are connected, and the invention relates to the technical field of polymerization reactors. The high-efficiency cleaning system and cleaning method for a polymerization reactor are provided with a connecting mechanism, and the sealing ring is connected with the sliding pipe and the conical sealing seat, so as to seal the inside of the pipe to prevent air from entering the inside of the reactor, resulting in prepolymerized material and condensation. The glue is difficult to clean. When the sealing ring moves away from the connection with the conical sealing seat, the material can flow through the inner wall of the sealing ring, so as to remove the gel and prepolymerized material from the inside of the reactor. The combination of the above structures solves the problem. There is a problem that the gel produced by the prepolymerization reaction adheres to the inside of the reactor and is difficult to remove.

Description

technical field [0001] The invention relates to the technical field of polymerization reactors, in particular to an efficient cleaning system and a cleaning method for a polymerization reactor. Background technique [0002] The prepolymerization of the existing continuous polymerization is carried out in a pipeline type reactor, the pipeline is jacketed outside, and there is a static mixing unit in the pipeline. Installed on the trolley, because the gel produced during the prepolymerization reaction has strong adhesion on the inner wall of the pipe and the surface of the mixing unit, it is very difficult to remove by ordinary solvent cleaning. [0003] At present, the replaced reactor needs to be disassembled, and the gel can be cleaned with a high-pressure water gun of 1000kg / cm2, and then assembled into a complete set after cleaning. The cleaning process is time-consuming and laborious, and a large amount of waste water is generated. Frequent disassembly and assembly also ...
