Abstract

The invention relates to the technical field of stripping towers and provides a stripping tower device with double overflow weir plates. The stripping tower device comprises a tower body and a base, wherein the tower body is fixedly arranged on the base and is an enclosed container, a steam outlet is formed in the top of the tower body, a feeding pipe is fixedly arranged on the upper part of the tower body, the interior of the cavity of the tower body is sequentially and fixedly provided with at least five tower plates at intervals from bottom to top, the upper end surface of the edge of each tower plate is respectively and fixedly connected with a pair of overflow weir plates, and one ends of each pair of the overflow weir plates are respectively and fixedly connected with the inner wall of the tower body. The stripping tower device disclosed by the invention has the advantages that the structure is reasonable and compact, the use is convenient, the purpose of removing VCM (vinyl chloride monomer) in slurry is realized through the matching use of the tower plates, a baffling device, the overflow weir plates and an overflow weir opening, the characteristics of safety and stability in operation and convenience in operation are provided, the labor intensity of operators is reduced, the production cost is reduced, the stripping efficiency is improved, and the yield requirements of the subsequent processes and the product quality are ensured.

Description

technical field [0001] The invention relates to the technical field of stripping towers, and relates to a stripping tower device with double overflow weir plates. Background technique [0002] Polyvinyl chloride monomers are polymerized by initiators in the polymerization tank. When the monomer conversion rate reaches 80% to 85%, a terminator is added to terminate the polymerization reaction. After the polymerization reaction, the slurry containing 20% ​​to 25% of PVC resin enters the discharge tank through automatic control, and the PVC plasticized block is removed by the dump pump and filter, and then enters the feed tank of the stripping tower. The polyvinyl chloride resin slurry in the feed tank of the stripping tower is pumped to the spiral plate heat exchanger of the stripping tower through the slurry pump, and exchanges heat with the hot slurry coming out of the stripping tower. The top layer of the stripping tower enters the stripping tower. The slurry entering th...
