High-relative molecular mass water-soluble polymers reactor

Abstract

The invention relates to a reaction kettle for a water-soluble polymer with high relative molecular mass. The reaction kettle can ensure the beginning reaction temperature, take away heat emitted by the reaction in time and carry out stirring on a solution in the reaction kettle. The reaction kettle comprises a kettle body. The reaction kettle is characterized in that the kettle body is arranged on a bracket through a rotating shaft arranged on two sides of the kettle body; a kettle cover of the reaction kettle is provided with a heat exchange column; and the exchange column extends into a kettle cavity of the reaction kettle.

Description

(1) Technical field [0001] The invention relates to a chemical production device, in particular to a high relative molecular mass water-soluble polymer reactor. (2) Background technology [0002] High relative molecular weight water-soluble polymers have very strict requirements on the polymerization conditions, especially the temperature requirements. The temperature in the initial stage of the reaction should not be too low, otherwise the polymerization will be initiated, and the temperature in the middle stage of the reaction should not be too high. The polymerization itself is an exothermic reaction. When the polymerization solution is polymerized into a certain gel state, the fluidity of the liquid is significantly reduced, and the heat of reaction cannot be dissipated, causing the local temperature to be too high, which reduces the relative molecular weight of the polymer. When the monomer content is high, implosion occurs. The relative molecular weight of the polymer ...

Problems solved by technology

[0003] For the existing high relative molecular weight water-soluble polymer reactor, it is a simple stainless steel cylinder, which cannot provide heat, and cannot exchange the heat generated by the polymerization reaction in time. Due to the low concentration, the subsequent drying costs are large, and the production The disadvantage of high cost, the present invention provides another high molecular weight water-soluble polymer reactor, which can ensure the initial reaction temperature, and can take away the heat released by the reaction in time, and can produce solid content of 30% -45% polymer at a lower cost
