Method and system for treating desulfurization waste gas

Abstract

The invention discloses a method and a system for treating desulfurization waste gas. The method comprises the steps as follows: 1) desulfurization waste gas is delivered from a desulfurization tank to a cooler for cooling through a first gas guide pipeline, and first desulfurization waste gas is obtained; 2) the first desulfurization waste gas is delivered from the cooler to an activated carbon adsorption device for adsorption through a second gas guide pipeline, and second desulfurization waste gas is obtained; 3) the second desulfurization waste gas is delivered from the activated carbon adsorption device to a boiler for combustion through a third gas guide pipeline, and third desulfurization waste gas, which is up to the standard, is obtained.

Description

technical field [0001] The invention relates to a method and system for treating desulfurized waste gas. Background technique [0002] In the reclaimed rubber industry, there are usually four ways to deal with desulfurization waste gas: 1) comprehensive purification of chemical agents; 2) purification of biological strains; 3) purification of activated carbon adsorption and 4) removal and purification of combustion. Due to the problems of 1) comprehensive purification of chemical agents and 2) purification of biological strains, there are problems such as high cost, difficulty in removing the peculiar smell of desulfurization exhaust gas, and production of other adverse reaction substances, so 1) comprehensive purification of chemical agents and 2) biological bacteria This purification is not widely used. At present, most enterprises use a single method such as 3) activated carbon adsorption purification or 4) combustion method to remove and purify desulfurization waste gas...

AI Technical Summary

Problems solved by technology

However, when using 3) activated carbon adsorption and purification to deal with desulfurization, there are the following problems: activated carbon is effective in a short period of time, and when the activated carbon is saturated, the desulfurization waste gas adsorbed on the surface of the activated carbon will be desorbed, thereby polluting the environment

When using 4) combustion method to remove and purify the way to deal with desulfurization, there are the following problems: desulfurization waste gas is flammable, explosive, toxic and harmful, and direct combustion will produce products that pollute the environment and have certain safety problems, such as tempering. explosion etc.
