Abstract

The invention discloses a drying system and method for polyvinyl chloride. The drying system comprises a slurry groove (1), a centrifugation device (2), a vibrating feeding device (3), a fluidization bed (4), a vibrating screen (6), a material bin (8) and volatile matter measuring devices (9), wherein the slurry groove (1) is used for containing polyvinyl chloride slurry, the centrifugation device (2) is used for conducting initial centrifugal drying on the polyvinyl chloride slurry so that polyvinyl chloride wet cake and centrifugation mother liquor can be obtained, the vibrating feeding device (3) is used for conveying the polyvinyl chloride wet cake to the fluidization bed, the fluidization bed (4) is used for conducting secondary fluidization drying on the polyvinyl chloride wet cake so that polyvinyl chloride semi-finished products can be obtained, the vibrating screen (6) is used for screening the polyvinyl chloride semi-finished products so that polyvinyl chloride products can be obtained, the material bin (8) is used for storing the polyvinyl chloride products, and the volatile matter measuring devices (9) are used for conducting volatile matter measurement on the polyvinyl chloride slurry, the polyvinyl chloride wet cake and the polyvinyl chloride semi-finished products. The drying system for the polyvinyl chloride can rapidly and effectively dry the polyvinyl chloride and achieves utilization of waste heat.

Description

technical field [0001] The invention relates to a polyvinyl chloride production process, in particular to a polyvinyl chloride drying system and drying method. Background technique [0002] Polyvinyl chloride is a heat-sensitive, porous powder material. Due to its pore structure, polyvinyl chloride tends to absorb a part of water. [0003] Excessive moisture content in polyvinyl chloride will lead to agglomeration, and if the time is long, it may also lead to mold, which not only affects the appearance and color of the product, but also brings difficulties to subsequent processing. [0004] Every increase of 0.1% in PVC moisture is equivalent to 0.001 tons of water per ton of PVC finished products sold to manufacturers at the price of PVC, which has a great impact on the economic benefits of manufacturers. Therefore, the moisture content of PVC has also become a concern of manufacturers. One of the important process indicators. [0005] Therefore, the drying of polyvinyl c...
