The invention discloses a treatment system and method for purifying stale garbage by adopting a plasma technology. The treatment system comprises a secondary combustion chamber, wherein the secondarycombustion chamber comprises a vortex combustion dust removal chamber provided with a dual-mode plasma ignition system, a joist barrow grab bucket is located above a feeding port of a material channel, a material pushing mechanism is arranged on one side of the material channel, the bottom of the material channel is connected to a first combustion chamber, the output end of the first combustion chamber is connected to the input end of a second combustion chamber, the output end of the second combustion chamber is connected to a waste heat steam boiler, the waste heat steam boiler is connectedto a screw type generator set and an economizer, wherein the output end of the economizer is connected to an air preheating system, the output end of the air preheating system is divided into two paths, one path is connected to the first combustion chamber, the other path is connected to a flue gas quenching device, and the flue gas quenching device, a bag-type dust collector, a spray tower and achimney are sequentially connected. According to the system, auxiliary fuel does not need to be added, and a large amount of land is saved, garbage does not need to be classified, and cost is greatlyreduced.
Description
technical field [0001] The invention relates to the technical field of stale garbage treatment, in particular to a treatment system and method for purifying stale garbage by using plasma technology. Background technique [0002] With the continuous improvement of people's living standards, the output of stale waste is also increasing. According to the statistics released by the Ministry of Housing and Urban-Rural Development, the annual production of stale waste in my country is more than 400 million tons, and the harmless treatment of stale waste has become It is related to the environment and the focus of people's life. [0003] The existing stale domestic waste treatment method is mainly waste incineration. Due to the complex composition of stale waste, the harmful substances such as smoke, leachate, slag and fly ash produced by stale waste incineration have caused increasingly serious pollution to the living environment. Among them, the most difficult thing is the treatm...
