Garbage cracking combustion tail gas treatment method

The invention discloses an industrial garbage cracking combustion tail gas treatment method. After tail gas sequentially goes through a cooling treatment tower, a multilayer filtering tower, a multilayer cloth bag deduster, a wet washing tower and a tail gas recirculating system, dust, heavy metal steam, organic matter, nitrogen oxide, nitrogen monooxide and irritant smell are removed effectively. The treatment method is high in deodorizing and purifying efficiency, and the multilayer filtering tower is small in adsorption resistance coefficient, low in energy consumption, less prone to being blocked, convenient for subsequent replacement, operation and maintenance and low in running cost. Purifying efficiency of the tail gas treated by a system is up to higher than 99%, and pollutant concentration is lower than national emission standards. 本发明公开了种工业垃圾裂化焚烧尾气处理方法，尾气依次经过降温处理塔、多层过滤塔、多层布袋除尘器、湿式洗涤塔、尾气再循环系统后，尾气中存在的粉尘、重金属蒸汽、有机物、氮氧化物、氧化氮以及刺激性气味被有效去除。本处理方法除味净化效率高，多层过滤塔吸附阻力系数较小、能耗低、不容易阻塞、后期更换操作维护方便、运营成本低。通过本系统处理的尾气净化效率
