Abstract： |
The invention discloses a method and equipment of purifying tail gas produced by burning garbage. With the tail gas produced by burning garbage being speeded up through contracting expanding nozzle, the said equipment sprays the gas into clarifier of circulating fluid bed on which calcium based deprivation agent and sorbent is laid and carried by the bed with flowing forward. On the flow, the gas, liquid, solid matter is mixed and heated strongly, it cause ultrafine particles of acid gases, heavy metal and dioxin etc. contained on the tail gas to occur neutral reaction and to be adsorbed by sorbent. the invention provides features with simple technical procedures, easy to be realized, notable depurative effect, tight structure, long investment and operating cost. |
