1、 摘要通过对烟气进行除尘、脱硫、除氮、脱氟等处理,从而减少废气中粉尘、硫氧化物、氮氧化物和氟化物的含量,以达到排放要求。对于除尘工艺,对设计经济和性能以及效率各方面进行考虑,对多种的除尘器进行比较,最终采用的是袋式除尘器,因为陶瓷废气中的粉尘基本上接近或属于超细粉尘,而袋式除尘器处理微小粒径的粉尘,具有效率高、性能好、操作简单等一系列优点。本设计采用活性炭吸附联合除硫脱销,主体设备是类似于吸附塔的活性炭固定床吸附器, 烟气中SO,在活性炭表面被氧化产生稀硫酸气溶胶,从而被活性炭很好的吸附。向吸附塔中喷氨气,与NO 在活性炭的催化还原作用下生成N,可实现脱硝的目的。吸附有SO 的活性炭进入吸附器
2、加热再生,再生出的SO 气体可以通过Clause反应回收硫,再生后的活性炭可以反复使用。氟化物的处理采用XFP系列含氯废气净化装置,采用石灰石和电石渣进行中和多级处理,使氟离子生成氟化钙而沉淀,净化后的废气通过除沫,去掉水分后由烟囱排出。关键词:烟气除尘,袋式除尘器,活性炭联合除硫脱氮,XFP系列含氯废气净化装置Abstract The waste gas via to proceed dedusting, desulfuration, denitrogenate, defluorination grade disposals etc,in order to decrease the conc
3、entration of mill dust, sulfur oxides, oxides of nitrogen and fluorid in waste gas, with the purpose of effluent specification. Baggy precipitator was chosen for dust removing,as it is better than other precipitator in considering the factors of economy and capability and efficiency. Because mill du

The active carbon which adsorpted SO2 go to thermal regeneration by sprinkling hot vapour,then sulphur in the regenerative SO2 gasses can be reclaimated by pouring the regenerative SO2 gasses into CLAUS equipment.Last
