specific Embodiment approach

[0025] Its specific implementation method is as follows: when the polymerization kettle is working, the material is input into the inside of the polymerization kettle body 1 from the feed port 101 through a certain pressure, and after a certain amount of material is input, the transmission device 6 is opened and drives the stirring shaft 3 and the stirring paddle 4 Stir, at this time, the material in the polymerization kettle body 1 starts to polymerize under the set pressure and temperature, and the material after the reaction is output from the discharge port 102; the heat generated by the polymerization reaction is cooled by the internal stirring system and the external jacket The cooling operation mode of the stirring system is that the cooling water flows in from the cooling water inlet 305 through a certain power, and enters the interlayer formed by the outer stirring shaft tube 301 and the central shaft tube 302 through the sleeve 307 and the cooling water inlet 3011 of t...

Abstract

The invention relates to a large special resin polymerization kettle for polyvinyl chloride, and belongs to the field of chemical machinery. The large special resin polymerization kettle comprises a polymerization kettle body, a stirring shaft, a stirring paddle, a shaft seal and a transmission device; the stirring shaft is of an inner-outer dual-layer hollow structure, and an independent cooling water inlet channel and an independent cooling water outlet channel are formed; the stirring paddle is of a hollow structure, and flow guiding channels are formed in the stirring paddle; a cooling water inlet channel and a cooling water outlet channel are formed between the stirring paddle and the stirring shaft, and the outer layer of the polymerization kettle body is provided with a cooling water clamping sleeve. According to the large special resin polymerization kettle, heat generated in the polymerization process is taken away through circulating flow of cooling water inside and outside the polymerization kettle simultaneously, uniform cooling of materials in the polymerization kettle can be effectively achieved, therefore, the polymerization process is kept at the temperature required by a technology, and the technological stability and the quality of polyvinyl chloride resin are improved.

Description

Technical field: [0001] The invention relates to the field of chemical machinery, in particular to a polyvinyl chloride large-scale special resin polymerization kettle. Background technique: [0002] Polyvinyl chloride (PVC) paste resin is widely used in imitation leather, wall wallpaper, gloves, flame-retardant conveyor belts, toys and other industries. With the market development and expansion of PVC paste resin, the demand for PVC paste resin has also further expanded, and the performance requirements and production capacity of PVC paste resin have also increased accordingly. Therefore, it is necessary to accelerate the improvement of the production process of PVC paste resin and increase the production capacity. At present, a large number of 50m3 polymerization kettles in use in China use micro-suspension polymerization technology. The mixture of vinyl chloride and water is dispersed in the polymerization kettle and reacted for 15-30 hours to form micro-suspension latex....
