The volatile organic compounds generated during applying forms poisonous and harmful Organic Waste Gas Pollution environment.
The poisonous and harmful organic exhaust gas generated in coating process mainly includes the organic solvent of paint grain and volatilization, and paint grain is micro-
It is small, viscosity is big, easy coherent substance surface；Many environmental protection equipments can only handle organic exhaust gas, and paint grain processing can not be gone
It removes.Paint grain content is not high, and partial size is smaller, and the overwhelming majority is at 10 μm hereinafter, quickly can when using activated carbon adsorption if unprocessed
Activated carbon capillary is blocked, active carbon is made to fail.Spraying exhaust gas not only contains volatile organic matter, also comprising suspending in spraying process
Aerial paint grain, paint grain will affect subsequent VOCs treatment, so needing to remove paint therein before lacquer spraying waste gas purification
Grain, so that next step is to wherein volatile organic matter purification treatment.
Traditional paint grain minimizing technology generally comprises wet purification method and dry cleaning method.
Wet purification method is to pass through the paint in solvent absorption (or chemical absorbing) lacquer spraying waste gas according to the similar principle that mixes
Grain, common wet purification method have water curtain type, without the processing method of purification such as pump water curtain style, venturi type, water rotation type.The purification device
It is that each phase borders on the river and interferes with each other between spigot air-flow there are problem, air-flow utilization rate is low, so that water spigot atomizing effect level is not
Together；Spray room bottom paint mud does not allow easy-clear, and maintenance of clean-up is difficult.
Dry cleaning method is that lacquer spraying waste gas is entered filter, utilizes the paint grain and particle in filtering layer detention lacquer spraying waste gas
Object commonly uses glass fibre cotton, clinker etc. and is used as filtrate.Theoretically filtration method can remove most of paint grain, and wave therein
Hair property organic matter is adsorbed on a small quantity.This method is without secondary pollution, does not generate waste water；The disadvantage is that filtering is not thorough enough, to equipment
It is seriously polluted, easily block.
Relative to wet purification method, dry cleaning method is not sufficiently stable in performance, but since U.S. etc. is by wet purification
Discharge is considered as danger wastes containing coating waste-water, and enterprise starts to abandon wet purification method, then be discharged using no waste water
Dry cleaning method.
The present invention develops a kind of airborne contaminant administering method and device containing sticky paint grain, very good solution viscosity paint
Grain is difficult to the technical problem purified.
Summary of the invention:
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of airborne contaminant improvement containing sticky paint grain

When, start the heater outside paint grain purification device, paint grain purification device is heated to 150-200 DEG C, is adhered on filter plate
The heated removing moisture of paint grain, desiccation, lose viscosity, be detached from filter plate under the action of blower, fall into paint grain purification device bottom
Portion；
3), the volatile organic matter in lacquer spraying waste gas from paint grain purification device by being discharged, into active carbon after filter plate
Adsorption cleaning is discharged into atmosphere through chimney finally by blower.
It is 2-5mm sieve pore that diameter has been evenly arranged on filter plate in the paint grain purification device.
Paint grain dust concentration is not more than 800mg/m in the lacquer spraying waste gas3。
A kind of device of the airborne contaminant administering method containing sticky paint grain, including paint grain purification device (4), active carbon are inhaled
The two sides of adnexa (7), blower (9), chimney (10), the paint grain purification device (4) are respectively provided with paint grain purification device entrance
(1) and paint grain purification device outlet (5), the outside of the paint grain purification device (4) are provided with heater (3), and the paint grain is net
Makeup, which is set, is arranged multiple filtration plate (2) inside (4), and the filter plate (2) is in paint grain purification device (4) tilted arrangement, and mistake
Filter plate interconnects between (2), and the paint grain purification device outlet (5) passes through the active carbon of pipeline and active carbon adsorber (7)
Absorber entrance (6) connection, the active carbon adsorber outlet (8) are successively connected with blower (9) and chimney (10) by pipeline.
The paint grain purification device (4) is cuboid reactor shape, and multilayer is arranged inside the paint grain purification device (4)
Filter plate (2), filter plate (2) is in tilted layout and adjacent head plate (2) interconnects, and each layer of filter plate (2) and paint grain purify
The angle of the bottom plate of device (4) is 60 °.
The working principle of the invention is briefly described as below:
A kind of airborne contaminant administering method containing sticky paint grain of the present invention carries out substep improvement for lacquer spraying waste gas, first
Purification first is filtered to the solid paint grain in exhaust gas, activated carbon adsorption then is carried out to the gaseous volatile organic matter in exhaust gas
Purification, is ultimately discharged into atmosphere.
When the present invention purifies the sticky paint grain in exhaust gas using paint grain purification device, it is filtered using multiple filtration plate,
Every layer of filter plate is in tilted layout, and the angle of filter plate and paint grain purification device is 60 °, when exhaust gas passes through paint grain purification device, by
It is in tilted layout in filter plate, leading to the motion profile of exhaust gas is in Wave curved, and the paint grain in exhaust gas is easy when passing through filter plate
With filter plate collision and because of sticky adhesive on filter plate, to realize that paint grain purifies；Since sticky paint grain is adhered to filtering
It on plate, is easy to cause equipment blocking to influence treatment effect and stablizes, heating device is set in outside, by being heated to 150-200 DEG C,
By the paint grain fast dewatering of adherency, dewatered paint grain loses viscosity after drying out, and under the induced effect of blower, falls into paint
Grain purification device bottom, had not only been able to achieve the removing of paint grain, but also was avoided that purification device blocks.
Beneficial effects of the present invention:
A kind of airborne contaminant administering method containing sticky paint grain has been invented, paint grain is efficiently intercepted using physics, is changed
Become exhaust gas motion profile, improve paint grain and filter plate collision probability, unique structure meet paint grain purification requirement, then into
The adsorption cleaning of row volatile organic matter realizes qualified discharge, solves the dry cleaning problem of paint grain improvement, and structure is simple,
Itself continuous and steady operation can be maintained, avoided because of the corrosion of equipment caused by wet-treating and secondary pollution.
