Polymerizer for producing polyacrylamide

Abstract

The invention discloses a polymerizer for producing polyacrylamide. According to the polymerizer disclosed by the invention, a layer of lining is arranged on the inner side of a polymerizer wall and consists of a plurality of lining plates, the plurality of lining plates are fixedly adhered to the inner side of the polymerizer wall by virtue of connecting parts, and the edges of the two adjacent lining plates are welded in a sealing mode. When the lining of the polymerizer is manufactured, the polymerizer is not needed to be disassembled, and a worker only needs to enter the polymerizer to fixedly mount each lining plate. Compared with the prior art, the technical scheme is capable of greatly simplifying the manufacturing process of the polymerizer, saving the manufacturing cost and time and thus improving the production efficiency.

Description

technical field [0001] The invention relates to the technical field of polyacrylamide production, in particular to a polymerization kettle for producing polyacrylamide. Background technique [0002] At present, the production of PAM (polyacrylamide) generally uses a polymerization tank. During the production process, because the polymer colloid sticks to the kettle wall, the lining enamel of the polymerization kettle is prone to problems of foaming, peeling, and colloid sticking to the wall. When discharging, the material liquid impacts the polymer sticking to the kettle wall. A large amount of foam will eventually affect product quality, and will reduce production efficiency and increase cleaning costs. [0003] The most traditional technical solution to solve the wall-hanging problem is mainly to reduce the degree of wall-hanging by spraying paint on the wall of the polymerization kettle, controlling process parameters, cleaning the wall of the polymerization kettle with ...

AI Technical Summary

Problems solved by technology

[0005] The above several technical solutions cannot completely solve the problem of hanging on the wall, but can only reduce the degree of hanging on the wall, but the problem still exists

Disadvantages of the polymerization kettle painting scheme: this method is only effective for a short period of time, and problems such as wall hanging and air bubbles will slowly begin to appear after one month; Disadvantages of the scheme of controlling process parameters: the actual effect is not ideal, and the effect is negligible; high-pressure water gun Disadvantages of cleaning the polymerization kettle solution: This method has a large workload, high cost, and low efficiency. It is feasible for short-term emergency use and is not suitable for long-term large-scale production. Only use can achieve the purpose, the workload is heavy, the production efficiency is low, and it is not suitable for long-term large-scale production

[0006] There are also disadvantages in the technical scheme of lining the polymerization kettle with polytetrafluoroethylene. The production cycle is long, and the polymerization kettle needs to be dismantled and transported to a designated place for production. Not only is the project huge, but the cost is too high
