Operation principle of the present utility model：During use, waste gas is passed through from air inlet, as ventilation duct is connected with uniform flow chamber,
Avoid extending into uniform flow intracavity, therefore waste gas can enter uniform flow chamber by ventilation duct.As waste gas is before this along ventilation duct to dirty
It is dynamic, active carbon layer is then passed through into after uniform flow chamber switch to flow up, its flow velocity will necessarily slow down, therefore waste gas is in uniform flow intracavity
There is the time diffusion of abundance, and then uniformly pass through from active carbon layer everywhere again.Due to activated carbon surface and organic exhaust gas molecule
Between attractive interaction effect produce physical absorption（Adsorb also known as Van der Waals）, so as to the organic component in waste gas is adsorbed in activity
The apparent gap of charcoal, is purified waste gas, purified gas, finally discharges from air outlet.
The beneficial effects of the utility model are：In this programme, as waste gas can be spread in uniform flow intracavity, then uniformly
Pass through from active carbon layer various pieces, be not in " dead angle " phenomenon that active carbon layer portion passes through without waste gas, increase
The comprehensive utilization ratio of active carbon layer is added.When switching to flow up from flowing downward due to waste gas, its flow velocity can slow down, therefore
More sufficient time and activated carbon effect are had in active carbon layer, the adsorption efficiency of active carbon layer is improved, away from test, this programme
Adsorption efficiency up to more than 90% to waste gas.
