Description
Technical field
The utility model relates to the process fields of volatile organic matter (VOCs), particularly relate to a kind of ultraviolet light photooxidation VOCs
Processor.
Background technique
VOCs exhaust gas is a kind of volatile organic compound from waste gas, the control technology of VOCs exhaust-gas treatment include combustion method,
Photocatalytic method, active carbon adsorption, absorption process, condensation method, biological treatment etc..It is useless for the VOCs with maladorous smell
Gas, it will usually processing be catalytically decomposed using ultraviolet light (UV) photooxidation, equipment is generally by blower and with quartz burner
Treatment channel is constituted.Existing photooxidation processing equipment is that several quartz burners are installed in the vertical direction with gas flow
, since photooxidation processing equipment is fairly simple, technological improvement is integrated with other VOCs processing units, such as
Chinese patent (publication number CN105921009A) discloses photooxidation combined exhaust gas processing unit and its processing method, is combined with and urges
Agent and photooxidation equipment are to VOCs processing；Chinese patent (publication number CN107349767A) discloses organic waste gas treatment device,
Photooxidation section is set in sequence, three conversion zones of catalytic ozonation section and bio-trickling section come to VOCs exhaust-gas treatment.Two specially
The thinking of benefit is to provide a variety of processing means to reach processing VOCs exhaust gas purpose, not to photooxidation processing equipment itself into
Row improves.
Utility model content
The purpose of this utility model is to provide a kind of wall attachment effects using air-flow, so that photooxidation effect greatly promoted
Ultraviolet light photooxidation VOCs processor.
To realize the purpose of this utility model, proposed adoption following technical scheme:
A kind of ultraviolet light photooxidation VOCs processor, which is characterized in that including processor body, photooxidation treatment channel, ultraviolet
Line fluorescent tube, the photooxidation treatment channel are aluminum tubular structure, and radial diameter is 145-200mm, quartz burner installation
On the center line of photooxidation treatment channel, ultraviolet radiator length of tube is suitable with photooxidation treatment channel length；The photooxidation processing is logical
Road quantity is no less than 2, and corresponding quartz burner quantity is suitable with photooxidation treatment channel quantity, adjacent photooxidation treatment channel
Outer wall close-packed arrays.Processor body is quadrangular shape, and photooxidation treatment channel is mounted in processor body, and photooxidation processing is logical
Road is axial parallel with processor body center line, i.e., consistent with gas flow.The quantity of photooxidation treatment channel is by processor body
Section size determine that, in general, the section size of processor body is a × b, photooxidation treatment channel diameter is φ, then photooxidation
The maximum quantity for the treatment of channel is a/ φ (round numbers) × b/ φ (round numbers).According to the bernoulli principle in hydrodynamics, stream
Body can slow down closer to the superficial velocity of object at gradient, and the slowing down of flow velocity will lead to fluid and be attracted to body surface upstream
Dynamic, this effect is also known as Coanda effect or wall attachment effect, that is to say, that when VOCs exhaust gas flows through several photooxidation equipment treatment channels
When, since photooxidation equipment treatment channel is circular tube structure, gas generates wall attachment effect when circulating, ozone and hydroxyl-free radical
Near-wall is all compressed in together with gas molecule, and all kinds of material densities probability that is evenly distributed is equal, ozone, hydroxyl-free radical pair
The probability of organic molecule oxidation reaction is also equal, since gas density prolongs tube wall and compressed and rapids can occur after the attached wall of air-flow
Stream, reaction density are also accordingly reinforced, and the treatment effeciency to VOCs gas is improved.
Preferably, the gap between the adjacent photooxidation treatment channel is sealed in both ends position, VOCs exhaust gas is prevented
It enters in the gap between adjacent photooxidation treatment channel.
Preferably, the quartz burner is connected with ballast and switch, convenient for controlling quartz burner.
Compared with prior art, VOCs is transported in several parallel photooxidation treatment channels by the utility model processor,
Using wall attachment effect, air-flow is compressed in the near-wall of photooxidation treatment channel, keeps air-flow abundant under quartz burner irradiation
Reaction, substantially increases the treatment effeciency to VOCs gas.
Detailed description of the invention
Fig. 1 is the utility model embodiment figure.
Fig. 2 is the Section A-A figure of Fig. 1.
Figure label are as follows: 1, air inlet；2, gas outlet；3, processor body；4, photooxidation treatment channel；5, ultraviolet radiator
Pipe.
Specific embodiment
Further illustrated below with reference to embodiment the technical solution of the utility model includes:
The utility model embodiment photooxidation VOCs processor includes processor body 3 combined with Figure 1 and Figure 2, and photooxidation processing is logical
Road 4 and quartz burner 5 are provided with air inlet 1 and gas outlet 2 in the front-end and back-end branch of processor body 3, along gas stream
To being provided with several aluminum tubulose photooxidation treatment channels 4,4 radial diameter of tubulose photooxidation treatment channel is 145mm, at photooxidation
It manages in channel 4, quartz burner 5, the external ballast of quartz burner 5 and switch is installed along 4 center line of photooxidation treatment channel,
In general, the section size for the treatment of mechanism machine body is a × b, photooxidation treatment channel diameter is φ, then the number of photooxidation treatment channel
Amount is ab/ φ, round numbers.In the present embodiment, the long a of Section A-A is 1050mm, and wide b is 1200mm, 4 diameter of photooxidation treatment channel
It is 145mm, the then quantity of photooxidation treatment channel 4 to diameter are as follows:
(rounding)=56 (1050 ÷ 145) (rounding) × (1200 ÷ 145)
Corresponding, quartz burner 5 is also 56.The utility model utilizes the wall attachment effect generated when airflow,
Ozone and hydroxyl-free radical are all compressed in near-wall together with gas molecule, all kinds of material densities probability that is evenly distributed is equal,
Ozone, hydroxyl-free radical are also equal to the probability of organic molecule oxidation reaction, since gas density prolongs tube wall after the attached wall of air-flow
