Efficient cleaning system for polymerization reactor and method thereof

Abstract

The invention discloses an efficient cleaning system for a polymerization reactor and a method thereof, a connecting mechanism comprises a sliding pipe and symmetrically arranged connecting pipes, one end of the sliding pipe is communicated with one end of the reactor through a flange, and the two connecting pipes are communicated through a spring pipe. The system relates to the technical field of the polymerization reactor. According to the efficient cleaning system for the polymerization reactor and the method thereof, the connecting mechanism is arranged, a sealing ring is connected with the sliding pipe and a conical sealing seat, so that the interior of a pipeline is sealed, and it is avoided that air enters the reactor, so that pre-polymerized materials and gel are difficult to clean, when the sealing ring moves away from the connection with the conical sealing seat, materials can flow through the inner wall of the sealing ring, so that the gel and the pre-polymerized materials are removed from the interior of the reactor, and the problem that the gel generated by the existing pre-polymerization reaction is adhered to the interior of the reactor and is difficult to remove is solved through the combination of the structures.

Description

technical field [0001] The invention relates to the technical field of polymerization reactors, in particular to a high-efficiency cleaning system and cleaning method for a polymerization reactor. Background technique [0002] The pre-polymerization of the existing continuous polymerization is carried out in a pipeline reactor with a jacket outside the pipeline and a static mixing unit inside the pipeline. The total length of the pre-polymerization reactor of each line is about 150 meters, and it is divided into four parts. Installed on the trolley, due to the strong adhesion of the gel produced during the prepolymerization process on the inner wall of the pipeline and the surface of the mixing unit, it is very difficult to remove it with ordinary solvent cleaning. [0003] At present, the replaced reactor needs to be disassembled, and the gel can be cleaned with a 1000kg / cm2 high-pressure water gun, and then assembled into a complete set after cleaning. The cleaning process...
