AI Technical Summary

Technical Problem

In existing continuous polypropylene production processes, fluctuations in exhaust gas temperature cause condensation or melting of the filter media, affecting filtration efficiency and shortening the filter media's lifespan, and there is a lack of precise temperature control mechanisms.

Method used

It adopts a thermal induction drive device, which automatically adjusts the exhaust gas temperature through a combination of rotating drum and cooling coil to ensure cooling within the range of 60~80℃, avoiding problems of excessively high or low temperatures.

Benefits of technology

It achieves precise control of exhaust gas temperature, improves filtration efficiency, reduces the risk of clogging, extends filter media life, reduces maintenance costs, and meets environmental protection requirements.

Abstract

一种聚丙烯连续生产用废气处理装置,属于废气处理领域,包括过滤箱和进气管,进气管与过滤箱相连通,进气管内设有冷却管,冷却管包括一排数个冷却盘管,冷却盘管通过连管串联连通连接,相邻的冷却盘管之间分别设有隔板和转动筒,隔板固定在进气管上,转动筒转动安装在进气管上,转动筒的封闭端面与对应的隔板滑动接触配合,转动筒的端面开设通气孔。本发明结构简单,构思巧妙,根据废气的温度,自动选择不同长度的冷却管对废气进行冷却,从而使废气被冷却在适当温度范围,避免被过滤的废气温度过高导致聚丙烯颗粒软化黏过滤板,或温度过低时导致过滤板上结露,进而使聚丙烯颗粒板结堵塞过滤板,从而提高过滤板的通透性,延长过滤板的使用时间。
