Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings, and the embodiments are not intended as a restrictive description of the present invention documents.
[0023] A chemical company discharges organic gas containing toluene during the product refining and drying process, with an exhaust volume of 4000m 3 / h, the concentration of organic matter in the gas is 6000mg / m 3 about. After the organic gas is collected by the pretreatment system, it is sent to the activated carbon fiber adsorption system through the waste gas fan. First, it enters the adsorber A and is absorbed. After stage adsorption, the purified air is discharged from the main discharge port.
[0024] As the adsorption progresses, the adsorber A gradually becomes saturated. When the adsorber A reaches saturation or the adsorption time is set, the adsorption process of the adsorber A ends, the air inlet of the adsorber A is closed, and the series pipe between t...
