Problems solved by technology

If these self-polymers are not washed in time, as the batch of polymerization reaction increases, the self-polymerized adhesives will increase to form large block-shaped self-polymers, which will cause the blockage and inaccuracy of the detection instrument in the horizontal tube. And cause the blockage of the condenser at the top of the polymerization kettle, the blockage of the condenser at the top of the kettle reduces the heat transfer efficiency of the kettle and increases the reaction time
At the same time, frequent blockage also shortens the cleaning cycle, increases the difficulty of cleaning the kettle, reduces the utilization rate of the polymerization kettle, and is extremely unfavorable to the production of paste resin

Abstract

The invention provides an automatic flushing device and method for a paste resin polymerization kettle. The device comprises a multistage centrifugal pump and a high-pressure water pipe. The multistage centrifugal pump is arranged on a pipeline of the high-pressure water pipe, a polymerization kettle condenser is located at the top of the polymerization kettle and is in a row tube type, circulation cooling water is placed in a shell side, and incoagulable vinyl chloride monomer is placed in a pipe side; the water outlet end of the high-pressure water pipe is arranged at the top in the condenser and is opposite to the pipe side. The automatic flushing device for the paste resin polymerization kettle is characterized in that the polymerization kettle condenser is provided with a spray nozzleand is automatically flushed, a flange of the tail end of a polymerization kettle pressure horizontal pipe is additionally provided with a flushing water port, and it is guaranteed that the horizontal pipe is flushed. Through program control, after a polymerization reaction is completed, a large amount of foam still exists in the sections of the pressure horizontal pipe and the condenser row tube, flushing water is used for successfully flushing the foam to prevent the foam from generating autopolymer, and the bonding probability of the autopolymer is lowered.

Description

technical field [0001] The invention belongs to the field of organic synthesis equipment, and in particular relates to a polyvinyl chloride synthesis equipment and an application method thereof. Background technique [0002] In the production process of polyvinyl chloride, the polymerization kettle is the key equipment for production. In the production process, in order to better remove the reaction heat in the reaction process, the top of the polymerization tank is equipped with a condenser, and due to the reaction characteristics of the paste resin, it is very easy to cause the blockage of the condenser on the top of the tank and the pressure horizontal pipe, and the whole For the paste resin industry, solving the problem of blockage of the polymerization kettle is a major difficulty in the production of paste resin. Therefore, through technical improvement, the self-polymers in the polymerization kettle should be washed in time to prevent further self-polymerization from ...
