The environment-friendly purification process comprises the following steps: opening a carbon box descaling control valve, a reflux control valve (water drops can be generated in the running process of equipment, and a water drop reflux pipe refluxes the water drops into a spray tower to reduce the running load of the equipment) and a second steam descaling control valve, opening a spray tower water pump and a fan in the carbon box, starting the plasma incinerator, closing a high-temperature steam inlet control valve, and closing a first steam descaling control valve and a third steam descaling control valve. Through workshop exhaust gas collection system, the contaminated air who collects is carried to the spray column in through sealed pipeline and is intake water and spray for the acid and alkali class, heavy metal class and some chemical pollutants that contain in the clear away air are administered, are neutralized preliminarily, thereby get rid of in the abandonment most can hold the pollutant in aqueous.
The residual stubborn pollutant molecules flow through the pipeline under negative pressure, firstly enter the rotary air inlet device after being dried and filtered twice, so that the rotary air inlet device rotates directionally, the rotary waste gas enters the high-temperature plasma incinerator to be burnt at the high temperature of more than 1600 ℃, and the staying and burning time of the air in the combustion chamber of the plasma incinerator is longer than that of the air in a straight-through manner when the air passes through the high-temperature plasma incinerator in a rotating manner, so that the air is more fully burnt, and the effect after the burning is better than that of the straight-through type waste gas.
The air after high-temperature plasma combustion is conveyed to the activated carbon adsorption box through a sealed pipeline, and the pollutants in the polluted air are adsorbed and treated by the activated carbon, so that the pollutants in the waste gas are further purified. The activated carbon box is adsorbed and purified layer by layer (a plurality of carbon plates), and is discharged into the atmosphere layer by a fan and a gas outlet chimney.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the invention.
