Description

A kind of UV lacquer tail gas air draft treating apparatus

[technical field]

The utility model relates to a kind of structure of air draft treating apparatus.

[background technology]

The exhaust duct of existing UV tail gas all is at exhaust duct exit exhaust fan, directly UV tail lacquer is discharged in the air, like this contaminated environment; Simultaneously, UV lacquer tail gas can solidify under solar radiation, and solidfied material is deposited on the blower fan, and influences the normal operation and the life-span of blower fan.

Because environmental protection requirement improves constantly, the continuation of environmental regulation is perfect, also some producer carries out the processing of UV lacquer spraying tail gas at present, adopt absorption cleaning mechanism, the mode that water drenches is coated with lacquer tail gas with UV and is absorbed, and its equipment is the absorption tower, and commonly used have packed tower and a plate column, its cost height, the device therefor costliness; And the UV tail gas that the absorption tower absorbs can not precipitate, and keep water to drench solubility to tail gas, handle water again, need regularly replace waste water simultaneously, also need handle before the discharge of wastewater, so processing cost is very high, and treating capacity can't reach 10000 to 20000m ³/ hour air mass flow, and owing to be to handle at wind exhausting outlet, still can contaminated air.

[summary of the invention]

Main purpose of the present utility model is: provide a kind of UV efficient, low-cost, environmental protection to coat with lacquer tail gas air draft treating apparatus.

For achieving the above object, the utility model proposes a kind of UV lacquer tail gas air draft treating apparatus, comprise exhaust duct, UV lamp, described UV lamp is installed in the described exhaust duct pipeline.

Fig. 1 is a kind of embodiment structure chart of UV lacquer tail gas air draft treating apparatus.

Fig. 2 is the partial structurtes schematic diagram in Fig. 1 embodiment.

[specific embodiment]

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Please refer to shown in Figure 1: the exhaust duct of the handled UV tail gas of this example mainly comprises compositions such as exhaust duct, active clapboard 5, UV lamp 4, UV lamp protective cover 41, blower fan 7.Exhaust duct comprises that first pipeline 1, second pipeline 2, the 3rd pipeline 3, the first pipelines 1, second pipeline 2 are straight tube, and the two is connected into the L type mutually; The 3rd pipeline 3 is the L type, and 2 one-tenth 90 degree of an end and second pipeline angle joins.The cross dimensions that is used to install first pipeline 1 of active clapboard 5 is 80cm*80cm, and area is 0.64m ²The cross dimensions of second pipeline 2 and the 3rd pipeline 3 is 80cm*40cm, and area is 0.32m ²Gas inlet is arranged at first pipeline, 1 head end tube wall place, and its diameter is 12cm, and long 10cm falls in order to increase the flow velocity and the pressure of air at mouth of pipe place, and its cross-sectional area is littler than the sectional area of first pipeline 1, and size can be fallen requirement according to enter the mouth flow velocity and pressure and be changed.12 to 20 active clapboards are installed in first pipeline 1 altogether,, are penetrated the time to guarantee UV illumination specifically by workshop height decision, the distance between adjacent two active clapboards be 10cm to 20cm, if the workshop height is enough, get 20cm.Please refer to shown in Figure 2ly, active clapboard 5 comprises diaphragm plate 51, cover plate 52, and the two becomes T type to join; Offer movable socket on the tube wall of first pipeline 1, in the diaphragm plate 51 insertion activity sockets, cover plate 52 cap seals are in movable spigot; During assembling, adopt rubber gasket 8 to seal, to avoid exhaust gas leakage.Staggered equidistant 12 UV lamps of installing between active clapboard, the F300S model that the UV lamp adopts Fusion UV system company to produce, power 1.8kw, wavelength 200 is to 320nm, power output 120w/cm as long as UV lamp wavelength and power output are enough, can select other brand.Be covered with UV lamp protective cover 41 outside the UV lamp 5, be used to protect the UV lamp, avoid cured granulate directly to fall on the UV lamp 5.Second pipeline 2 is horizontally disposed with; be connected with 1 one-tenth an angle of 90 degrees of first pipeline; second pipeline, 2 tube walls offer a sedimentation mouth; adopt a sedimentation base plate 21; be connected with second pipeline, 2 tube walls with screw; and be sealed in sedimentation mouth place with rubber gasket; under the exhaust gas flow state; do not reach on the sedimentation base plate 21 that the cured granulate of falling on the active clapboard can drop to second pipeline 2; and sedimentation base plate 21 can be dismantled easily, clean, and can directly change standby clean sedimentation base plate or load onto former sedimentation base plate again after cleaning up.Second pipeline, 2 tube walls block most of cross section of first pipeline, 1 outlet, and first pipeline 1 is narrowed with the air flue that is communicated with of second pipeline 2; Sedimentation plate washer 9 before the import department of second pipeline 2 sets up is set up back sedimentation plate washer 10 in the exit of second pipeline 2.

When installing and using, blower fan 7 is installed in the 3rd pipeline 3 exits.Blower fan 7 selects for use Germany to execute hundred happy axial flow blower FT types, power 3.5kw, and exhaust air rate 20000 is to 40000m ³As long as, satisfy the exhaust air rate requirement, can select the blower fan of other brand.

The device of this example, in the time of in working order, UV lamp 4 standard-sized sheets guarantee that first pipeline 1 loads onto active clapboard 5, and sealing, blower fan 7 with 10000 to 20000m ³Flow work; After UV lacquer spraying tail gas was drawn into first pipeline 1, under the irradiation of UV lamp 4, wherein the curing of the UV of gaseous state lacquer was fallen on the active clapboard 5; UV lacquer spraying tail gas enters in second pipeline 2; because the effect of preceding sedimentation plate washer 9 and back sedimentation plate washer 10; the tail gas flow velocity that is in second pipeline 2 is descended to some extent, do not reach and fall that cured granulate can drop on the sedimentation base plate of second pipeline 2 on the active clapboard, further purified tail gas.

The device of this example can regularly be extracted active clapboard 5 out cleaning, or change active clapboard 5; Can regularly replace UV lamp protective cover, avoiding cured granulate to be attached on the UV lamp protective cover influences the UV luminous intensity; But the sedimentation base plate 21 on periodic cleaning second pipeline 2.The every work of UV lamp was changed in 8000 hours one.Also can come to determine the replacing or the cleaning frequency of above-mentioned each part as the case may be.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.For example: the size of the sectional area of each segmentation of exhaust duct changes according to the needs of exhaust emissions flow and flow velocity, fundamentally guarantees the irradiation time that UV lacquer tail gas solidifies required UV lamp.The closure of the 3rd pipeline 3 can adjust according to the scene, can connect into the Z font with second pipeline 2.
