Description
Technical field
The utility model is related to a kind of low-temperature plasma purifying device of additional adsorption unit.
Background technology
Lower temperature plasma technology employs dielectric impedance corolla discharge technology and big flow electricity frequency high-voltage corona discharge skill
Art, substantially increases the quantity of cation, significantly improves its oxidability.In the presence of extra electric field, medium discharge can
Substantial amounts of high energy electron is produced, these electron bombardment contaminant molecules make its ionization, dissociate and excite, then by a series of
Complicated physics, chemical reaction, makes complicated macromolecule contaminant be changed into simple small molecule safe material, or make venomous injurant
Qualitative change into the low evil of nontoxic or low toxicity material so that pollutant be able to degraded removal.
It is useless in low concentration application VOCs although lower temperature plasma technology can reach excellent effect in deodorant application
Treatment effect in gas is still undesirable, and treatment effeciency only has 70% or so.Main cause be emission molecule or active specy wait from
Residence time in son is shorter, and the effective rate of utilization of discharge energy is relatively low.
Utility model content
The utility model aims to overcome that above-mentioned the deficiencies in the prior art, there is provided a kind of to low concentration application VOCs waste gas
The low-temperature plasma purifying device that addition of absorbing unit for the treatment of effect.
The technical solution of the utility model is：A kind of low-temperature plasma purifying device of additional adsorption unit, including housing,
The housing is respectively arranged at two ends with air inlet and gas outlet, along air inlet toward being sequentially provided with flow-disturbing on the direction of gas outlet in housing
Fan, primary filter, dry filter and low-temperature plasma generation device, the fan include blower tray and fixation
Fan main body on the blower tray, the blower tray is taper framework and is fixed on the inner side of the air inlet, institute
State and sealing ring is provided between the side of primary filter and dry filter and the inner walls, the primary filter and dry
Multi-disc spoiler is additionally provided between formula filter, the baffle liner of taper of being gathered on spoiler described in multi-disc is respectively disturbed adjacent to one another
Baffle liner on stream plate is separately oppositely arranged, and the low-temperature plasma generation device includes fixed mount, is fixed on fixed mount
Tubular negative electrode and the anode composition being interspersed in negative electrode, porous adsorption layer is also filled with the negative electrode.
Further, the housing is tubular, and the air inlet and the gas outlet are all taper.
Preferably, the spoiler has two panels.
