【摘要】：提出了一種廢棄PCB板熱拆解回收過(guò)程尾氣治理方法,其特征是待處理尾氣首先經(jīng)過(guò)活性炭吸附裝置,濾除尾氣中的固體粉塵、重金屬顆粒、部分無(wú)機(jī)非金屬氧化物以及部分有機(jī)氣體等;再將預(yù)處理后的尾氣通入噴淋塔,使其與噴淋塔中的堿性凈化液充分反應(yīng),去除大部分無(wú)機(jī)非金屬氧化物和部分有機(jī)氣體;最后將噴淋塔頂部排出的尾氣通入高溫燃燒設(shè)備進(jìn)行燃燒處理,最終排放出無(wú)污染的氣體。試驗(yàn)結(jié)果表明,該方法有效地解決了廢棄PCB板熱拆解回收過(guò)程的二次污染問(wèn)題,同時(shí)部分利用了尾氣中可燃?xì)怏w成分。
[Abstract]:In this paper, a method of removing waste gas from waste PCB plate is proposed, which is characterized by that the tail gas to be treated is first treated by activated carbon adsorption device to filter the solid dust and heavy metal particles in the tail gas. Some inorganic nonmetallic oxides and some organic gases, and then the tail gas after pretreatment is passed into the spray tower to fully react with the alkaline purifying liquid in the spray column to remove most of the inorganic nonmetallic oxides and some organic gases. Finally, the exhaust gas from the top of the spray tower is put into the high temperature combustion equipment for combustion treatment, and the non-polluting gas is discharged finally. The experimental results show that this method can effectively solve the secondary pollution problem in the process of thermal decomposition and recovery of waste PCB plate, and partly utilize the combustible gas composition in the tail gas.
