Problems solved by technology

[0004] The purpose of the present invention is to provide a waste gas treatment method based on activated carbon to solve the problem that the waste gas in the petrochemical industry generally has organic waste gas, and when the organic gas in the waste gas is treated, if activated carbon is used, after the activated carbon is saturated, the cost of replacing the activated carbon is relatively high.

Embodiment 1

[0033] like figure 1 As shown, the waste gas treatment method based on activated carbon of the present invention comprises the following steps:

[0034] Step A for waste gas treatment: first open the valves 10 between the filter device 4 and the adsorption tank 2 and between the fan 3 and the adsorption tank 2, and close the remaining valves 10;

[0035] Start the fan 3 again, so that the fan 3 absorbs the air in the exhaust gas source 1 in the filter device 4, and the filter device 4 filters the exhaust gas to remove tiny suspended particles in the exhaust gas;

[0036] Then the fan 3 sucks the filtered waste gas into the adsorption tank 2, and the adsorption tank 2 absorbs and retains the organic matter in the waste gas through the activated carbon arranged therein;

[0037] Finally, the fan 3 discharges the gas obtained after being processed by the adsorption tank 2 to the atmosphere;

[0038] Step B Activated carbon analysis treatment: first close the valves 10 between t...

Abstract

The invention discloses a waste gas treatment method based on activated carbon. The method comprises the following steps that in step A, a fan is turned on, so that air in a waste gas source is adsorbed into a filtering device under the effect of the fan, the filtering device is used for filtering the waste gas, and tiny suspended particles in the waste gas are removed; then the fan is used for sucking the filtered waste gas into an adsorption tank, organic matters in the waste gas are adsorbed and retained by the adsorption tank through activated carbon arranged in the adsorption tank; and finally, the air treated by the adsorption tank is discharged to the atmosphere through the fan; and in step B, an air pump is turned on, high-temperature low-pressure steam enters the adsorption tank,the organic matters adsorbed by the activated carbon in the tank are stripped from the activated carbon; and then the gas after stripping enters a cooler to be cooled and then enters a separator, andthe separator is used for recovering an organic solvent and sending the recovered organic solvent into a collector. Through the invention, the chemical waste gas is treated, the emission is facilitated, and the environment is protected; and meanwhile, through a heating and dissociation system, the activated carbon can be repeatedly used, so that the cost of treating waste gas is reduced.

Description

technical field [0001] The invention relates to the petrochemical field, in particular to a waste gas treatment method based on activated carbon. Background technique [0002] The main components of crude oil are: oily (this is its main component), colloid (a viscous semi-solid substance), asphaltene (dark brown or black brittle solid substance), carbonaceous (a non-hydrocarbon) . Petroleum is a colored, flammable oily liquid with a special smell, mainly composed of hydrocarbons. Natural gas is a colorless, flammable mixed gas with a special odor composed of gaseous hydrocarbon-based gases. The division of labor in the entire petroleum system is relatively fine: the chemical substances that make up petroleum can be decomposed by distillation. As processed products, crude oil includes kerosene, benzene, gasoline, paraffin, asphalt, etc. Strictly speaking, petroleum is mainly composed of hydrocarbons composed of hydrogen and carbon, and the four hydrocarbons with the small...
