A kind of polymerization reactor component and its using method

Abstract

The invention discloses a polymerization reactor assembly and a method for using the same, which are used for the reaction using or containing acrylamide as a raw material. The blowing pipeline (6) is connected to the gas source 10, the bottom of the kettle body (1) is provided with a discharge port and connected to the granulation device, and the kettle body (1) is provided with a lubricating liquid inlet (2‑1, 2‑ 2, 2‑3, 2‑4), each lubricating liquid inlet (2‑1, 2‑2, 2‑3, 2‑4) is connected to the lubricating liquid adding pipeline (5) to deliver the lubricating liquid. The introduction of lubricating liquid into the polymerization reactor assembly and its use method of the present invention reduces the resistance of the polymer being pressed out of the polymerization reactor after the polymerization reaction is completed, reduces the gas pressure required in the reactor body, and can appropriately increase the volume of the equipment. Improve efficiency, reduce energy consumption, and effectively reduce the probability of occurrence of press-through phenomenon.

Description

technical field [0001] The invention relates to a polymerization reactor component in the chemical industry and a method for using the same, in particular to a reactor component and its control process for polymerizing a colloidal high molecular polymer with or containing acrylamide as a raw material. Background technique [0002] Polyacrylamide polymers are one of a class of mass-produced water-soluble polymers. It is used in petroleum, water treatment, papermaking, textile printing and dyeing, agriculture and other fields. [0003] In the preparation of polyacrylamide products, there is a type of polyacrylamide polymerization product or copolymer that forms a whole gelatinous polymer in a polymerization reactor, with a water content of 65-80% and strong viscoelasticity. [0004] A polymer treatment process is to extrude the large colloidal polyacrylamide colloid from the bottom of the polymerization tank into a special screw extrusion pulverizer, and then pass through the...

Problems solved by technology

[0006] Nevertheless, under some specific polymer conditions, the extrusion of colloidal polymers is sometimes difficult to carry out, especially high molecular weight polyacrylamide colloidal polymers, sometimes due to excessive friction between the wall of the kettle and the overall rubber block And the air pressure applied in the kettle is relatively high (0.3-0.6MPa), and the pressure at the screw machine at the discharge port is normal pressure, which causes the pressure difference between the upper and lower sides of the rubber block to be too large, causing the rubber block to be pressed through up and down, forming a perforation, and being pressed through The final rubber block loses the downward air pressure, that is, it loses the power to extrude the pulverizer to the screw below, which requires a long standing process to wait for the rubber block to gradually recover under gravity, and then continue to apply pressure for the discharge operation , Sometimes it is even necessary to disassemble the reactor for manual cleaning, which affects the production efficiency. At the same time, the manual cleaning of the operator is labor-intensive
