Polyacrylamide production line

Abstract

The invention relates to a polyacrylamide production line. A reactor prefilter, an oil inlet lubrication polymerization reactor, an oil inlet lubrication smashing and pelleting device and a polyacrylamide colloid drying production line are connected in sequence, and the polyacrylamide colloid drying production line is respectively connected to a screening and grinding device and a pulse dust tail gas treatment device. The polyacrylamide production line is simple in structure, impurities in polyacrylamide production raw materials can be effectively filtered, the discharging time of a reactor is shortened, the amount of polymerization reactions is increased, colloid pelleting can be effectively lubricated, colloidal particles with the grain diameters of about 4 mm are obtained while the molecular weight of polyacrylamide is not reduced, required drying air quantity and energy consumption are reduced, the drying condition and standing time of materials are easily adjusted and controlled, the production capacity and product quality are improved, and the tail gas is effectively dedusted.

Description

technical field [0001] The invention relates to polyacrylamide production technology, in particular to a polyacrylamide production line. Background technique [0002] The production of polyacrylamide is based on the aqueous solution of acrylamide as the raw material, under the action of the initiator, the polymerization reaction is carried out, and the polyacrylamide rubber blocks formed after the reaction are cut, granulated, dried and crushed, and finally the polyacrylamide product is obtained . Raw materials such as acrylamide aqueous solution are usually directly added to the reactor for polymerization, and impurities in the raw materials directly affect the solubility of polyacrylamide products. During the polymerization of raw materials, the traditional reactor is in the shape of a cylinder, and the material is directly discharged from the outlet at the bottom. It is difficult to discharge the polyacrylamide in the shape of a rubber block. In the subsequent drying pro...

AI Technical Summary

Problems solved by technology

Traditional vibrating fluidized bed dryers are used to dry polyacrylamide by drying medium, and the drying medium is directly discharged, which wastes heat energy and is not conducive to energy saving and emission reduction

After the polyacrylamide colloidal particles are dried, they are separated by a cyclone separator. After the polyacrylamide colloidal particles are separated, the tail gas still contains fine particles. Dust is directly retained, the speed of dust retention is fast, and the dust removal efficiency of the filter bag is reduced rapidly, resulting in frequent pulse blowback dust removal, the dust collector has a short filtering time and low efficiency, and the equipment is easily damaged due to frequent switching
