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 invention provides a drying system and technology of high chlorinated polyethylene resins. The drying system comprises an airflow drying feeding device and an inner heated fluidized bed drying device, wherein the airflow drying feeding device comprises an air heat exchanger and a material transporting fan; the air heat exchanger is connected with the material transporting fan; a high chlorinated polyethylene resin charging pipeline is arranged in a pipeline between the air heat exchanger and the material transporting fan; the inner heated fluidized bed drying device adopts a tubular structure; a material inlet is formed in one end of the tubular structure in the axial direction, and a material outlet is formed in the other end of the tubular structure in the axial direction; three drying chambers are sequentially arranged from the material inlet to the material outlet; a partition board is arranged in every two adjacent drying chambers, and is provided with a port; drying chamber heat exchangers are arranged in the first two drying chambers; an inlet of each drying chamber heat exchanger is connected with a hot water source; a wind chamber is arranged at the bottom of each drying chamber; a wind distribution board is arranged between each drying chamber and the corresponding wind chamber; the inlet of each wind chamber is connected with a thermal wind source; and an outletof the material transporting fan is connected with a material inlet of the inner heated 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...
