the washed organic waste gas enters the coke oven 120 through the tail gas pipeline 140 and passes through the shutter 130 to burn. The volatile organic compounds can be treated, the yield and the output of chemical products can be improved, the running cost of VOCs treatment equipment is offset, the emission of coked Volatile Organic Compounds (VOCs) is reduced, higher benefits can be increased, and the positive benefits of VOCs treatment are realized.
The final product of the process does not contain VOCs, realizes continuous up-to-standard emission of VOCs, does not need to install an on-line VOCs monitoring device, and saves on-line equipment investment and maintenance cost.
The treatment process of the organic waste gas is particularly suitable for the treatment of volatile organic matters of coking enterprises, a new upper combustion furnace is not needed, investment, safety risk and energy consumption are reduced, and the process saves the operation cost by at least 200 ten thousand yuan compared with a new upper combustion furnace device. Has good social benefit, economic benefit and environmental protection benefit.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
