The first step, filter progress adopts described waste gas filter that the solid phase particles in the described multi-phase multi-component waste gas is isolated;
Second step, the component separation circuit is sent into the absorption tower with the multicomponent waste gas that obtains after the filtration treatment by exhaust gas fan, utilizes the organic solvent gas washing, the waste gas of the one-component of acquisition;
In the 3rd step, absorption process is sent into the waste gas of the one-component that obtains in the first absorber, utilizes carbon fiber layer that the organic solvent in the waste gas of one-component is adsorbed, the waste gas of the one-component after obtaining to purify;
The 4th step, desorption step, the steam supply device is sent steam into carbon fiber layer and has been reached in the second saturated absorber of absorption, under the effect of high-temperature steam, the organic solvent that is adsorbed on the carbon fiber layer surface is got off by desorption, obtain stripping gas, through condensation, separating technology, form valuable solvent and be recovered utilization;
The 5th step, drying process, the waste gas of the one-component after the purification of the 3rd step acquisition is sent into the 3rd absorber that carried out absorption process and desorption step by drying air fan, carbon fiber layer is carried out drying, thereby reach the moisture that removes in the carbon fiber layer and the waste gas of the one-component of oil-containing is carried out the purpose of double purification.
9. method as claimed in claim 8, it is characterized in that: if the multicomponent EGT that obtains through filter progress is higher, can also between filter progress and component separation circuit, add the operation that cools, multicomponent waste gas is sent into first gaseous effluent carry out cooling down, send into again component separating device.
10. the application of the described multi-phase multi-component waste gas treatment equipment of claim 1 to 7 in chemical engineering industry is produced.
