    活性炭吸附净化装置概述及原理

     1 概述 
    有机废气净化方式颇多,如直接燃烧,催化燃烧,但其对于低浓度,大风量的废气很难完全燃烧,在间歇作业中余热不能充分利用,对低浓度、大风量或间歇作业产生的废气采用活性炭吸附法有其独特优点,HXF型废气净化装置应用活性炭吸附原理,和吸附同类产品特点改进设计。本装置处理风量较大、采用气动阀门,操作管理简单安全。 
    2 使用范围 
    2.1、治理喷漆、包装、印刷、机械、化工及生产过程产生苯类、酯、醇、酮、醛、酚汽油等场合。 
    2.2、用于大风量、低浓度的废气工况或间歇作业中准备回收利用的有机溶剂工厂车间。 
    3 装置结构和特点 
    本装置主要包括:吸附罐、冷凝器、分离器、曝气器、主排风机等设备,配有进出口阀,炭层超温报警自动降温装置及电控柜等。 
    本净化装置可根据生产工艺设定单罐和双罐,间隙性生产一般设立单罐;连续性生产设立两个吸附罐,一只吸附,一只脱附,也可两罐同时使用。装置的进出风口设置手动阀门,操作简便可靠。本装置采用低压蒸汽为解吸介质,高沸点的溶剂解吸时可配备蒸汽过滤器,提高蒸汽温度。两罐也可同时吸附,定期同时解吸,处理风量可增加近一倍,对于间歇性生产可减少投资和占地面积。 
    4 工艺流程及原理 
    活性炭,具有很多微孔及很大的比表面积,依靠分子引力和毛细管作用,能使溶剂蒸汽和挥发性物质吸附于其表面,又根据不同物质的沸点,用蒸汽将吸附物质析出。当采用蒸汽为解除吸介质时解吸出的有机溶剂蒸汽与水蒸汽一起通过冷凝器凝结,进入分离桶经分离后回收有机溶剂。残液经曝气处理后排放。

    5 用户选用需知 
    5.1装置的废气进口温度应低于50℃,如高于50℃的废气需增加空气冷却装置,冷却后进入吸附罐。 
    5.2用于喷漆作业等产生的含有较多颗粒粉尘废气净化,废气应先对颗粒物进行过滤净化。
    5.3当吸附的有机溶剂沸点较高(120℃以上)时,可采用蒸汽过滤器,提高解吸蒸汽温度 
    5.4如没有蒸汽供应时,可随净化装置专门配备小型电热蒸汽发生器。

    1 Overview
    Quite a lot of organic waste gas purification, such as direct combustion, catalytic combustion, but for the low concentration of waste gas, the air is difficult to completely burn, the waste heat cannot be used fully in the intermittent operation, the waste gas in low concentration, large air flow or intermittent operation of the activated carbon adsorption method has its unique advantages, HXF type exhaust gas purification device application of activated carbon adsorption and adsorption principle, characteristics of the improved design of similar products. The device volume is larger, the pneumatic valve, simple operation and management security.  
    2 use range
    2.1, painting, printing, packaging, management and production machinery, chemical process to produce benzene, esters, alcohols, ketones, aldehydes, phenols gasoline etc..  
    2.2, for the preparation of organic solvent recycling plant using exhaust gas workshop operation or intermittent operation of large air flow and low concentration of.  
    3 device structure and characteristics of
    This device mainly comprises an adsorption tank, a condenser, separator, aerator, exhaust fan and other equipment, is equipped with inlet and outlet valves, carbon layer temperature alarm device and automatic temperature control cabinet etc..  
    The purification device can be set according to the production process of single tank and double tank, intermittent production general set up a single tank; continuous production set up two adsorption tank, an adsorption desorption, one can also be used at the same time, two cans. Air inlet and outlet device of the manual valve, easy to operate and reliable. The device adopts low pressure steam as the desorption medium, high boiling point of the solvent desorption can be equipped with steam filter, improve the steam temperature. The two tank can also adsorption, desorption and regular treatment, can increase the volume nearly doubled, to reduce investment and occupation area of intermittent production.  
    The 4 process and principle
    Activated carbon has many pores and large specific surface area, depending on the molecular attraction and capillary action, the solvent vapor and volatile substances adsorbed on its surface, and according to the different boiling point material, steam adsorption material precipitation. When the organic solvent using steam to remove suction aspiration solution medium steam together with steam through the condenser condensate into the separation barrel after separation of organic solvent recovery. The residual liquid is discharged after aeration treatment.
    5 selected users need to know
    The exhaust gas inlet temperature of the 5.1 device should be less than 50 degrees, such as exhaust gas above 50 DEG C to increase air cooling device, after cooling into the adsorption tank.  
    5.2 for the spray generated particles containing more dust and waste gas purification, waste gas should be of particulate filtration.
    5.3 when the adsorption of organic solvent (high boiling point above 120 DEG C), can be used to improve the desorption temperature of the steam steam filter,
    5.4 if there is no steam supply, with purification device specially equipped with small electric steam generator.  
     
    Note: 1, the company can undertake all kinds of special requirements, special design specifications.
    2, equipment foundation concrete level ground pressure is determined according to the weight of the equipment.
