The activated carbon adsorption method is a method for purifying waste gas by using activated carbon as an adsorbent and carrying out adsorption concentration on harmful substances in gas on the surface of a huge solid phase of the activated carbon. It possesses the advantages of high treatment efficiency and less investment, etc., and is specially applicable to intermittent small-batch production. The active carbon adsorbs purifying box branch wind section, active carbon filter segment and air-out section, and organic waste gas gets into the box from the air intake, and tail gas up to standard after the purification is arranged to the atmosphere under the ventilation blower suction.

First filtering: the V-shaped paper dry filter (fire-proof type) removes large particle impurities in the exhaust gas and moisture in the exhaust gas.

The V-shaped filter paper has the characteristics that: paint filter paper adopts imported swiss kraft paper, and the structure of fold effectively absorbs the overspray of super scope, forces the filtration air current to change the direction flow many times, and the coating cloud granule in the air adheres on filter paper, can not take away along with the air current, and fire prevention V type paper filter adopts fire prevention paper filtering material, and paint adsorption efficiency is strong, good continuous air current stability, and the air current is unobstructed to guarantee better spraying condition and better surface quality control, the spraying quality is higher. The operation cost is low, the service life is longer, the operation is easy, the installation is convenient, and the environment-friendly recovery can be realized.

Second activated carbon and third: the air is powered by a fan, and enters the box body under positive pressure or negative pressure, unbalanced and unsaturated molecular attraction or chemical bond force exists on the surface of the activated carbon solid, so that when the surface of the activated carbon solid is contacted with the air, the molecules of the air can be attracted, concentrated and kept on the surface of the solid, pollutants are adsorbed, and waste gas enters an equipment dust exhaust system after passing through a filter, so that purified gas is discharged at high altitude up to the standard.

The discharged gas enters a UV light oxygen purifier 1900, and the UV light oxygen purifier 1900 is provided with a UV light oxygen layer 1901, a plasma layer 1902, and an electric field layer 1903 in this order. UV: ultraviolet rays.

The device further comprises a purifier discharging device 2100 and a sampling monitoring device, wherein the purifier discharging device 2100 is connected with an outlet of the UV light oxygen purifier 1900, and the purified gas is discharged by the centrifugal fan 2000. The sampling monitoring device is connected with the outlet of the UV light oxygen purifier 1900 or the centrifugal fan 2000.
