Abstract
The utility model discloses a coating production waste gas purification device, which comprises a shell; one end of the shell is provided with an air inlet, and the other end of the shell is provided with an air outlet; the inner cavity of the shell is sequentially provided with a dust removal filter screen, an active carbon filter screen, a fan, a photocatalyst plate and an ultraviolet lamp from the air inlet to the air outlet. Compared with the traditional single purification mode, the utility model has the advantages of more thorough purification and good purification effect after dust removal, adsorption and catalytic oxidation treatment.
Description
Technical Field
The utility model relates to the technical field of coating processing purification, in particular to a coating production waste gas purification device.
Background
In the process of production is carried out to coating, need heat the boil out to coating, consequently coating can produce waste gas in the course of working, if directly discharge the waste gas that coating produced into the air, then can produce the pollution to the air, harm human health and harm environment because the waste gas of need to coating is handled the rear and can be discharged into the atmosphere.
At present, the waste gas treatment in the production of coating production enterprises is mostly carried out by adopting an activated carbon adsorption mode. However, the pollutant adsorption effect is not obvious and the treatment effect is poor by using only a single activated carbon.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a coating production waste gas purification device, which improves the treatment effect on coating production waste gas.
In order to solve the technical problems, the technical scheme of the utility model is as follows:
a coating production waste gas purification device comprises a shell; one end of the shell is provided with an air inlet, and the other end of the shell is provided with an air outlet; the inner cavity of the shell is sequentially provided with a dust removal filter screen, an active carbon filter screen, a fan, a photocatalyst plate and an ultraviolet lamp from the air inlet to the air outlet.
Further, a pair of guide plates are symmetrically arranged on the inner side wall of the shell; the guide plate is positioned between the exhaust port and the ultraviolet lamp.
Furthermore, one side of the guide plate, which is close to the ultraviolet lamp, is arc-shaped.
Furthermore, the activated carbon filter screen is conical.
Furthermore, the activated carbon filter screen is curved.
The utility model has the beneficial effects that:
by adopting the technical scheme, the dust removal filter screen can be used for carrying out preliminary dust removal and filtration on the coating waste gas; when the coating waste gas after preliminary dust removal and filtration passes through an active carbon filter screen, large-particle suspended matters in the waste gas are adsorbed; the waste gas after the two processes is irradiated by the ultraviolet lamp, harmful gas in the waste gas is catalyzed and oxidized by the photocatalyst plate, and finally the purified waste gas is discharged from the exhaust port.
Compared with the traditional single purification mode, the utility model has the advantages of more thorough purification and good purification effect after dust removal, adsorption and catalytic oxidation treatment.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, a coating production exhaust gas purification device includes a housing 1; one end of the shell 1 is provided with an air inlet 2, and the other end is provided with an air outlet 3; the inner cavity of the shell 1 is sequentially provided with a dust removal filter screen 4, an active carbon filter screen 5, a fan 6, a photocatalyst plate 7 and an ultraviolet lamp 8 from the air inlet 2 to the air outlet 3.
The photocatalyst plate 7 in this embodiment is composed of two layers of wire mesh with a coating of nano titania supported on the surface thereof and porous particles loaded with nano titania filled between the two layers of wire mesh. Of course, the photocatalyst plate 7 may be of other types conventionally used in the art.
Further, a pair of guide plates 9 are symmetrically arranged on the inner side wall of the shell 1; the deflector 9 is located between the exhaust port 3 and the ultraviolet lamp 8. Through the setting of guide plate 9, be convenient for lead the waste gas after the purification to gas vent 3 to discharge better.
Furthermore, one side of the guide plate 9, which is close to the ultraviolet lamp 8, is arc-shaped. The guide plate 9 of the arc-shaped design has a better drainage effect.
Further, in order to increase the contact area between the exhaust gas and the activated carbon filter screen 5 and improve the exhaust gas purification effect, the activated carbon filter screen 5 is tapered or curved.
The working principle of the utility model is as follows:
during the operation, waste gas gets into through air inlet 2 under fan 6's effect, goes out most dirt through dust removal filter screen 4, then through the active carbon filter screen 5 of taper or curved surface form, further goes out the large granule suspended solid in the waste gas, and waste gas after two above-mentioned processes are handled receives the photocatalyst board that the ultraviolet lamp shines, harmful gas in the waste gas is catalytic oxidation, and the waste gas after final purification is discharged from the gas vent.
Compared with the traditional single purification mode, the utility model has the advantages of more thorough purification and good purification effect after dust removal, adsorption and catalytic oxidation treatment.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, and the scope of protection is still within the scope of the utility model.
