Adsorption purification tower principle and technological process
吸附净化塔原理和工艺流程
Adsorption purification tower process, system design, the accessory equipment is complete, high purification efficiency. In the domestic leading position. It is widely used in petroleum, chemical, rubber, paint, coating, printing and other industries, the release of benzene waste gas, and other organic waste gas are can purify. It can effectively purify the environment, eliminate pollution, improve the operating conditions of labor, to ensure that health workers, and can recycle organic solvent, reduce the production cost.
吸附净化塔过程中,系统设计、附属设备完成,净化效率高。在国内的领先地位。广泛应用于石油、化工、橡胶、油漆、涂料、印刷等行业,苯的释放废气,和其他有机废气净化。它能有效地净化环境,消除污染,改善劳工的工作条件,确保卫生工作者,并能回收有机溶剂,降低生产成本。
Adsorption purification tower device has the advantages of compact structure, cover an area of an area small, management, maintenance is simple and safe operation.
吸附净化塔设备具有结构紧凑,占地面积小,管理、维护简单和安全运行。
Adsorption purification principle and process flow
吸附净化原理和工艺流程
1, adsorption:
1、吸附:
Organic waste gas through the filter to remove solid particulate matter, top-down into adsorption tank, organic matter was activated carbon capture, adsorption and enrichment, purify the air from the tank bottom by the main fan into the atmosphere.
有机废气通过过滤除去固体颗粒物,自上而下的吸附罐,有机物被激活碳捕获,吸附和富集、净化空气从罐底的主要风机到大气中。
2, desorption
2、解吸
After activated carbon adsorption of organic saturated state, stop to inhaled organic waste gases. By activated carbon bed up to blow off steam, will from activated carbon from organic matter, the desorption. Jar activated carbon to recover its activity, that is, regeneration.
经过活性炭吸附的有机饱和状态,停止吸入有机废气。通过活性炭床上发脾气,会从有机质、活性炭解吸。Jar活性炭恢复活动,即再生。
3, hot air drying and cooling:
3、热风干燥和冷却:
After steam desorption of active carbon layer, with about 80 to 90% of the steam condensate, filled with activated carbon inner hole, the activity of reducing the carbon layer. Therefore, bubbled into the hot air to dry carbon layer. And then close the steam valve, ventilation with normal temperature, air cooling to 25 ℃ or so, activated carbon to bounce back, for recycling use.
蒸汽活性炭层的解吸后,约80 - 90%的蒸汽冷凝水,充满了活性炭内孔,减少了碳的活动层。因此,通入热空气干燥的碳层。然后关闭蒸汽阀、通风与正常温度、空气冷却到25℃左右,活性炭反弹,回收使用。
4, organic solvent recovery:
4、有机溶剂回收:
Advantage of the characteristics of organic solvent dew point temperature is higher, the condenser, introduced a mixture of steam and organic solvent, the condensation, condensate trap into the separator, advantage of the characteristics of solvent is lighter than water, separation recycling.
利用有机溶剂的特点露点温度较高,冷凝器,介绍了蒸汽和有机溶剂的混合物,冷凝,冷凝阱到分离器,利用溶剂比水轻的特点,分离回收。
5, condensate water purification:
5、冷凝水净化:
In order to guarantee the clean of the condensed water, avoid condensate water discharged into water bodies, organic solvent in the separator after the separation of the water into the air, make water organic solution sufficient relief. The compressed air from the organic turn-back exhaust system, air adsorption. After purification, the condensed water, sewage.
为了保证冷凝水的清洁,避免冷凝水排入水体,有机溶剂在分离器分离后的水到空气中,使水有机溶液充分的救济。有机折回的压缩空气排气系统,空气吸附。污水净化后的冷凝水。
6, regeneration cycle:
6、再生循环:
Regeneration cycle should be according to exhaust the harmful gas concentration after purification. When the harmful gas concentration near excessive value, namely, should stop adsorption and regeneration. Determination of initial working stages should be timely help system discharge harmful gas concentration, in order to grasp the reasonable adsorption regeneration cycle.
再生周期应根据排气净化后的有害气体浓度。有害气体浓度过度值附近时,即应停止吸附和再生。确定初始阶段工作应及时帮助系统排放有害气体浓度,为了掌握合理的吸附再生周期。
7, continuous adsorption measures:
7、连续吸附措施:
In continuous production factory, the adsorption system also needs corresponding work continuously, can be in the exhaust gas purification system design, choose double pot series, so that alternate adsorption and regeneration of continuous use.
在连续生产工厂,不断吸附系统也需要相应的工作,可以在废气净化系统设计,选择双锅系列,这样交替吸附和再生连续使用。
