Problems solved by technology

The moisture in the material exists in the form of internally bound water, which requires a long drying process. Due to the above-mentioned special properties, the drying process of high-chlorinated polyethylene is very different from that of similar materials such as chlorinated polyvinyl chloride. systems cannot dry HCPE

Abstract

The disclosure provides a drying system and process for high-chlorinated polyethylene resin. The drying system includes an airflow drying feeding device and an internal heating fluidized bed drying device; the airflow drying feeding device includes an air heat exchanger, a feeding fan, and an air heat exchange The feeder is connected to the feeding fan, and the pipeline between the air heat exchanger and the feeding fan is provided with a high-chlorinated polyethylene resin feeding pipeline; the inner heating fluidized bed drying device is a cylindrical structure, and the axial end of the cylindrical structure is provided with a material Inlet, the other axial end of the cylindrical structure is provided with a material outlet, three drying chambers are arranged in sequence from the material inlet to the material outlet, two adjacent drying chambers are provided with partitions, the partitions are provided with openings, and the first two drying chambers are There are drying room heat exchangers in the room. The inlet of the drying room heat exchanger is connected to the hot water source. There is an air chamber at the bottom of each drying room. There is an air distribution plate between the drying room and the air chamber. The inlet of the air chamber is connected Hot air source; the outlet of the feeding fan is connected to the material inlet of the inner heating fluidized bed drying device.

Description

technical field [0001] The disclosure belongs to the production field of high-chlorinated polyethylene, and relates to a drying system and process of high-chlorinated polyethylene resin. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] High chlorinated polyethylene is high chlorine content chlorinated polyethylene, also known as HCPE resin. Small white light particles, relative density 1.35-1.45, apparent density 0.4-0.5, chlorine content > 65%, thermal decomposition temperature > 130°C, thermal stability time 180°C > 3mm. Since the molecular structure does not contain double bonds and the chlorine atoms are randomly distributed, it has good weather resistance...
