A kind of pollutant treatment device
Technical field
The utility model relates to pollutant treatment field, particularly relates to the pollutant treatment device that spraying production and processing is used.
Background technology
When workpiece carries out spraying production, need to adopt cascade to be received by the vaporific paint vehicle waste residue produced in atmosphere during spraying to make it to discharge with water, prevent the paint vehicle waste residue in air from affecting the respiratory system of staff, prevent the aerial excessive concentration of paint vehicle residue from occurring the potential safety hazard of blast.When workpiece toasts in baking oven simultaneously, the paint vehicle on its surface has part and evaporate in air, needs air to discharge to eliminate safe hidden trouble.In Workpiece painting production process, create waste water and waste gas, need the paint vehicle residue removed in waste water and waste gas just can discharge, avoid contaminated environment.Traditional waste water, exhaust-gas treatment mode be utilize screen pack, filter cloth bag filters, but filter effect is poor, effectively can not remove the paint vehicle residue in waste water, waste gas, screen pack, filter cloth bag need frequent replacing simultaneously, replacing maintenance man-hours is long, labour intensity is high, and treatment effeciency is low.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition improves prior art, a kind of pollutant treatment device is provided, solve pollutant treatment slagging-off weak effect in current technology, need frequently to change filter assemblies, labour intensity high problem.
For solving above technical problem, the technical solution of the utility model is:
A kind of pollutant treatment device, comprise settling tank and emission-control equipment, it is characterized in that, be provided with deflected current wall in described settling tank, settling tank is separated in several regions by deflected current wall, and deflected current wall offers seepage flow mouth, emission-control equipment comprises the washing section and blower fan that connect successively, the drying room waste gas outlet that washing section docking is outside, produces negative pressure by blower fan and waste gas is sucked washing section, and the waste water that washing produces flows into settling tank sedimentation except Slag treatment.The mode of pollutant treatment device employing sedimentation described in the utility model removes the paint vehicle residue in waste water, paint vehicle residue accumulate in settling tank a certain amount of after draw out again, squeeze, landfill, can effectively improve slagging-off efficiency, reduce hand labor intensity, water after the slagging-off cascade for arriving during spray process capable of circulation, recycle energy-saving and emission-reduction, reduce production cost.The waste gas produced in spraying drying room makes the residue in air be received by moisture by washing, thus greatly reduces the residue in waste gas, improves slagging-off effect, has received the moisture of residue to flow in settling tank again and carried out settlement treatment.
Further, in skewed bottom described settling tank, paint vehicle residue in infall process can be made to be accumulated in the bottom of inclined plane, conveniently to draw out, reduce labour intensity.
Further, in described washing section, spray equipment is set, sprays vaporific moisture by spray equipment, waste gas is fully contacted with water, improve the effect that moisture receives residue, reduce the dregginess in waste gas as much as possible.
Further, in described spray equipment washing section, waste gas course is provided with three groups, improves slagging-off effect, reduce discharge.
Further, in described washing section, be also provided with moisture separator, make the separated removal of aqueous vapor of not condensing in atmosphere, reduce the dregginess in air further.
Further, described emission-control equipment is also provided with active carbon layer in the outlet of blower fan, removes other impurity and peculiar smell in air, purifies air, and reduces discharge.
Compared with prior art, the utility model advantage is:
Pollutant treatment device described in the utility model effectively removes the paint vehicle residue in waste water and waste gas, reduce discharge, recycle the rear moisture of slagging-off, production cost is low, and too much intervene without the need to artificial, reduce hand labor intensity, slagging-off efficiency is high, continuous operation is good, changes parts without the need to frequent maintenance; The utility model structure is simple, and cost of manufacture is low, high financial profit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of pollutant treatment device disclosed in the utility model embodiment, effectively removes the paint vehicle residue in waste water, waste gas, reduces discharge, improves the feature of environmental protection, without the need to manual intervention, reduces labour intensity, improves treatment effeciency.
As shown in Figure 1, a kind of pollutant treatment device, comprise settling tank 1 and emission-control equipment 2, deflected current wall 3 is provided with in settling tank, settling tank 1 is separated in several regions by deflected current wall 3, and deflected current wall 3 offers seepage flow mouth 4, in skewed bottom settling tank 1, being convenient to paint vehicle residue is accumulated in together, reduces the labour intensity that staff draws out paint vehicle residue.
Emission-control equipment 2 comprises the washing section 5 and blower fan 6 that connect successively, impurity and the peculiar smell of active carbon layer 9 withhold excessive is also provided with in the outlet of blower fan 6, washing section 5 docks outside drying room waste gas outlet, spray equipment 7 is set in washing section 5, in spray equipment 7 washing section 5, waste gas course is provided with three groups, the moisture of atomization is utilized fully to contact with waste gas, moisture is made fully to receive paint vehicle residue, improve slagging-off effect, also be provided with moisture separator 8 in spray equipment 7 after washing section 5 and remove the moisture do not condensed have passed through, dregginess in further reduction air, produce negative pressure by blower fan 6 and waste gas is sucked washing section 5, the waste water that washing produces flows into settling tank 1 sedimentation except Slag treatment.
Below be only preferred embodiment of the present utility model, it should be pointed out that above-mentioned preferred embodiment should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
