Polymerization feeding optimization system and method

Abstract

The invention discloses a polymerization feeding optimization system and an optimization method. The polymerization feeding optimization system comprises dispersing agent kettle inlet pipelines, initiator kettle inlet pipelines and flushing pipelines; the dispersing agent kettle inlet pipelines are in on-to-one correspondence with dispersing agent storage tanks. The optimization method sequentially comprises the steps of water and monomer feeding, initiator preparation, first dispersing agent feeding, first dispersing agent mixing for 1 min and second dispersing agent feeding. According to theinvention, each dispersing agent is provided with an independent kettle inlet pipeline, and the flow of the dispersing agent is metered through a mass flow meter, so that the material preparation occupation time is reduced, the polymerization kettle feeding procedure is effectively simplified, the kettle feeding time is shortened, the single-kettle production capacity is improved, and the yield can be improved by 4.4%; meanwhile, metering, washing and process monitoring are all carried out through electronic equipment, a manual confirmation procedure in a traditional process is replaced, manpower is saved, and meanwhile the metering accuracy and the working efficiency of the whole kettle feeding process are effectively improved.

Description

technical field [0001] The invention relates to the technical field of optimization of feed to a polymerization kettle, in particular to a system and method for optimizing feed to a polymerization. Background technique [0002] At present, the feeding process of the 70m³ polymerization kettle is as follows: first add soft water and monomer, then add a dispersant A solution in order, then add another dispersant B solution, and finally add an initiator solution to start the reaction. Among them, the dispersant feeding procedure is as follows: the dispersant circulation pump first pumps the dispersant into the metering tank for weighing, and then uses the tank pump to pump the dispersant into the polymerization tank after the accumulated net content reaches the formula amount. In the process of metering into the kettle with metering tanks, both dispersants need to manually confirm whether the amount of residual roots before material preparation meets the requirements. The prepa...

AI Technical Summary

Problems solved by technology

In the process of metering into the kettle with metering tanks, both dispersants need to manually confirm whether the amount of residual roots before material preparation meets the requirements. The preparation of materials takes a long time and the metering tank needs to be rinsed twice during feeding of each dispersant. , which leads to a longer feeding time and affects the production capacity of the single kettle

The existing optimizations are all aimed at the feeding time of the dispersant, and most of them are optimized from the aspects of shortening the preparation time. Although a certain improvement effect can be obtained, they cannot fundamentally solve the problem of cumbersome operation of the original feeding system, and cannot be greatly improved. Significantly shorten the feeding time of dispersant
