Description

用于烟草制丝废气的除尘除异味处理系统 Dust removal and odor removal treatment system for waste gas from tobacco shred

技术领域technical field

本实用新型涉及一种废气处理系统，具体地，涉及一种用于制烟业制丝工艺产生的废气的除尘除异味处理系统。The utility model relates to a waste gas treatment system, in particular to a dust removal and deodorization treatment system for the waste gas produced in the silk-making process of the tobacco industry.

背景技术Background technique

制丝工艺产生的异味气体的特点：较高温(40-50摄氏度左右)、低尘(3-5mg/m3)、低湿(80％左右)、较高浓度(10000OU)、大风量。The characteristics of the odorous gas produced by the silk making process: higher temperature (about 40-50 degrees Celsius), low dust (3-5mg/m 3 ), low humidity (about 80%), higher concentration (10000OU), and large air volume.

传统制丝除尘除异味的废气处理系统基本采用单一异味处理工艺来处理制丝除尘后异味，如多级化学洗涤或活性炭吸附方法，其存在缺点有：洗涤方法处理效果只能在70％，只能去除溶解于水的异味物质，对非水溶性异味物质再反复洗涤也无济于事，所以在传统单一洗涤方法就是存在着处理效率问题，使得很多烟草企业处于城市中心区环境，周边居民反应空气质量的呼声强烈。活性炭吸附处理初始效果确实很好，但使用6个月后效果明显下降，主要原因活性炭的解析无法使活性炭完全释放异味，累月的积累异味使活性炭无法吸附，只能采用再次投资更换活性炭，以保持处理效果，成本较高。但在目前节能减排的国际发展形势下，活性炭吸附的方法已非大势所趋。The traditional waste gas treatment system for dust removal and odor removal in silk making basically adopts a single odor treatment process to deal with the odor after dust removal in silk making, such as multi-stage chemical washing or activated carbon adsorption methods. It can remove odorous substances dissolved in water, and repeated washing of non-water-soluble odorous substances will not help. Therefore, there is a problem of processing efficiency in the traditional single washing method, which makes many tobacco companies located in the central area of the city, and surrounding residents respond to air quality. The voice is strong. The initial effect of activated carbon adsorption treatment is indeed very good, but the effect decreased significantly after 6 months of use. The main reason is that the analysis of activated carbon cannot completely release the odor of activated carbon. To maintain the treatment effect, the cost is higher. However, under the current international development situation of energy saving and emission reduction, the method of activated carbon adsorption is no longer the general trend.
