The invention discloses a gas purification device, which comprises an air outlet
pipe, a purification collection cover, a pull-type
activated carbon filter layer a, a pull-type
activated carbon filterlayer b, a
gas cylinder a, an air inlet, device legs, a dust residue collecting bucket a, a dust residue discharging
pipe a, a device body, a connecting
pipe, a pull-type
activated carbon filter layer c, a pull-type activated carbon filter layer d, a
gas cylinder b, a dust residue collecting bucket b and a dust residue discharging pipe b. The double cylinders and double-layer pull-type activatedcarbon filter
layers are used for organic
waste gas filtration, and the device has the advantages of large
filtration flow rate and high adsorption efficiency. The double-layer pull-type activated carbon filter
layers have the
advantage of convenient replacement of a
filter element, and organic
waste gas containing
odor enters the
gas cylinder a and the gas cylinder b, and an upper double-layer pull-type activated carbon filter layer effectively adsorbs organic
waste gas such as
benzene, alcohols, ketones, esters,
gasoline and the like in the
exhaust gas, and the device can be applied to a plurality of mixed exhaust gases containing odors.
