工厂废气处理常用组合工艺有哪些?

来源:http://www.spormac.net/   发布时间:2019-04-24 16:47:25
一般工厂废气处理包括了有机废气处理、粉尘废气处理、酸碱废气处理、异味废气处理和空气杀菌消毒净化等方面。
  General factory waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment and air disinfection and purification.
  工厂废气处理又称废气净化。废气处理指的是针对工业场所、工厂车间产生的废气在对外排放前进行预处理,以达到国家废气对外排放的标准的工作。
  Factory waste gas treatment is also known as waste gas purification. Exhaust gas treatment refers to the pre-treatment of the exhaust gas produced in industrial sites and factory workshops before it is discharged, so as to meet the national standards for the external emission of exhaust gas.
  1、某些气体的处理可采用单元处理工艺,各种单元处理工艺适合于不同的处理对象。含有粒子污染物的气体常采用旋风分离、过滤、静电捕集和湿式洗涤;硫氧化物处理常采用吸收和吸附;
  1. Some gases can be treated by unit treatment process, and various unit treatment processes are suitable for different treatment objects. Gases containing particulate pollutants are usually separated by cyclone, filtered, electrostatic trapped and wet scrubbed, while sulfur oxides are usually treated by absorption and adsorption.
  2、新港废气处理公司介绍,对于中小型锅炉烟气的处理,可以采用多管旋风除尘+喷淋脱硫工艺或采用湿式洗涤除尘器, 并向洗涤水中加入适量的加碱性吸收剂。
  2. Xingang Waste Gas Treatment Company introduced that multi-tube cyclone plus spray desulfurization process or wet scrubbing dust collector could be used for flue gas treatment of small and medium-sized boilers, and alkaline absorbent could be added to the washing water.

  3、催化裂化催化剂再生烟气的处理,建议要用以下三种组合工艺:
  3. The treatment of regenerated flue gas from catalytic cracking catalyst is suggested to use the following three combined processes:
  a) 再生器吸附脱除SOx、CO锅炉静电除尘;
  (a) The regenerator adsorbs and removes SOx and CO boiler electrostatic precipitation;
  b) 再生器吸附脱除SOx、NOx、CO锅炉静电除尘;
  B) Removal of SOx, NO X and CO by regenerator adsorption;
  c) CO锅炉静电除尘湿式洗涤吸收脱硫。
  C) CO boiler electrostatic precipitation wet scrubbing absorption desulfurization.
  4、含高浓度有机废气的处理,可以采用的方法处理。如丙烯晴装置尾气处理。
  4. The treatment of organic waste gas with high concentration can be carried out by some methods. For example, tail gas treatment of acrylonitrile unit.
  5、对于发电机组烟气的处理,则可能选用湿式石灰石、石膏法或炉内喷钙尾部增湿脱硫静电除尘等工艺组合工艺组成。
  5. For the treatment of generator flue gas, wet limestone, gypsum or electrostatic precipitation with Calcium Spraying at the tail of the furnace may be selected.
