Specific embodiment
Referring to Fig.1, a kind of UV photodissociation machine, including hollow shell 1, shell 1 has air inlet 2 and gas outlet 3, in shell
It is provided with multiple partitions 5 in 1, the inner space of shell 1 is separated into the air flue 6 bent back and forth, head end and the shell 1 of air flue 6
Air inlet 2 is connected to, and the tail end of air flue 6 is connected to the gas outlet 3 of shell 1, and the direction of air-flow is provided with primary in air flue 6
Filtering area and photodissociation area are provided with filter screen 7 in primary filter area, and filter screen 7 and the inner wall of shell 1 are connected and fixed, in light
Solution is provided with multiple groups photocatalyst net 8 and the ultraviolet source for irradiating photocatalyst net 8 in area, and photocatalyst net 8 is obliquely installed.
The working principle of the UV photodissociation machine are as follows: external blower blasts foul waste gas in shell 1, and exhaust gas is from air inlet 2
It flows into, subsequently enters air flue 6, exhaust gas passes through filtering area during by air flue 6 before this, by strainer 7 by the drift in exhaust gas
Floating object filters out, and the exhaust gas after filtration treatment then passes through photodissociation area, exhaust gas contacted with photocatalyst net 8 after in ultraviolet light
Under the irradiation in source, the pernicious gas accelerated decomposition in exhaust gas is at ozone and other substances, to realize the deodorization to exhaust gas.
The quantity of photocatalyst net 8 in the present embodiment is three groups, exhaust gas bending flowing back and forth in air flue 6, with three groups of light
Catalyst network 8 contacts, and by the catalytic decomposition of three groups of photocatalyst nets 8, the pernicious gas in exhaust gas can be made to decompose more thorough, mentioned
Rise the effect of deodorization.
In order to which the exhaust gas for blasting air blower more swimmingly enters in air flue 6, in the present embodiment, ground air inlet 2 in shell 1
Place is provided with deflector 4, and deflector 4 is connected with the partition 5 of 6 head end of air flue.
In addition, the ultraviolet source in the present embodiment includes with the support plate 9 disposed in parallel of photocatalyst net 8, along air-flow side
To the multiple sockets 10 being arranged in support plate 9 and the ultraviolet lamp 11 being inserted into each socket 10.It is so arranged ultraviolet
Light source can sufficiently be irradiated to each position on photocatalyst net 8 so that exhaust gas pass through photocatalyst net 8 during in photocatalyst
Each region of net 8 can be effectively catalytically decomposed, to effectively promote the catalytic action of photocatalyst net 8.
In addition, each socket 10 in support plate 9 here is using connection type in parallel.Because socket 10 in parallel is mutual
Passing through for electric current is not influenced between phase, even after having the short circuit of ultraviolet lamp 11 or open circuit, other ultraviolet lamps 11 still can be after
Continuous work, ensure that the reliability of ultraviolet source.
It is noted that the quantity of filter screen 7 is four groups in the present embodiment, four groups of filter screens 7 are distributed along airflow direction,
And it is gradually become smaller along the aperture of the direction each group filter screen 7 of air-flow.It is designed so that filtering area can be to different size of
Floating material carries out classified filtering, that is, can guarantee outstanding filter effect, and can reduce the probability that each strainer 7 is blocked.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
