Abstract
The invention discloses a system for treating air pollution caused by furniture production. A dust negative pressure collecting system and a paint spraying exhaust port of a paint spraying waste gas negative pressure collecting system are located in a waste gas mixing box, and viscous oil paint particles in oil paint waste gas and dust are mixed so that the viscous oil paint particles can be removed in a precipitation mode; in combination with the effect of filter cotton on the exhaust port, the viscous oil paint particles in the oil paint waste gas are completely removed; meanwhile, gas-solid separation work of dust waste gas is completed; after mixed waste gas is subjected to spraying washing and activated carbon adsorption, the purification rate is larger than 99% and can reach or exceed the secondary standard in the integrated emission standard of air pollutants (GB16297-1996). The waste gas treatment amount can reach the scale of 50,000 m<3>/h. Activated carbon can be reused. The occupied area is small, and equipment manufacturing cost, maintenance cost and use cost of integrated overall treatment of air pollution caused by furniture production are all greatly reduced.
Description
Technical field
The present invention relates to the system that integrated treatment is carried out in air pollution that a kind of Furniture manufacturing causes.
Background technology
The air pollution caused of furniture enterprise is mainly derived from dust that timber processing link causes and furniture and sprays paint the waste gas that link causes.Wherein, dust is generally adopt negative-pressure pipeline systematic collection then to carry out gas solid separation, as sack cleaner etc.; The organic exhaust gas such as the benzene,toluene,xylene containing higher concentration in lacquer spraying waste gas, sticky paint particle is also carried secretly in this waste gas, adhere in emission-control equipment and make it lose effect, as the active carbon in active carbon absorption plant, often become block by oiliness particle adhesion, form the row of stealing and in line phenomenon that cannot economically use continuously.Can process waste gas after must carrying out pretreatment, pretreatment measure of the prior art carries out gravitational dust collection etc. as circulation fluid curtain or by cascade, its equipment manufacturing cost, maintenance cost, use cost are all higher, processing speed or treating capacity less, paint sticky particle has residual, and furniture enterprise air pollution region is large, exhausted air quantity large, be difficult to applicable prior art.
Summary of the invention
In order to solve above-mentioned drawback, technical problem to be solved by this invention is, provides a kind of air pollution total system being suitable for furniture enterprise.In order to solve the problems of the technologies described above, the technical solution used in the present invention is, a kind of Furniture manufacturing air pollution treatment system, comprise dust negative pressure gathering system and lacquer spraying waste gas negative pressure gathering system, it is characterized in that, also comprise waste gas blending bin, the dust exhaust outlet of described dust negative pressure gathering system and the exhaust outlet that sprays paint of lacquer spraying waste gas negative pressure gathering system are positioned at waste gas blending bin, and dust exhaust outlet and the exhaust outlet that sprays paint are oppositely arranged; In described waste gas blending bin, below is dust deposit chamber, and in described waste gas blending bin, top is provided with case exhaust outlet; Described case exhaust outlet is provided with filter cotton layer, and case exhaust outlet is communicated with Water spray tower, and Water spray tower exhaust outlet is communicated with activated carbon adsorption bed, and activated carbon adsorption bed exhaust outlet is communicated with chimney; Dust exhaust outlet and spray paint between exhaust outlet and dust deposit chamber and be provided with guiding cone, guiding cone both sides are provided with two blocks of anti-wing plates that backflow, and the anti-wing plate root that backflows is fixed on waste gas blending bin inwall, and the anti-wing plate that backflows tilts downwardly guiding cone; Anti-backflowing between wing plate and guiding cone leaves gap.
Beneficial effect of the present invention is, adopt technique scheme, the pretreatment of paint waste gas mainly through with having mixed of dust waste gas, make to paint sticky paint particle in waste gas and mix dust and be able to sedimentation and remove, the effect of combined filtering cotton, makes sticky paint particle in paint waste gas be able to whole removal; Complete the gas solid separation work of dust waste gas simultaneously; After mixing, waste gas is after spray washing and charcoal absorption, and purifying rate is greater than 99%, can meet or exceed the secondary standard in " discharge standard of air pollutants " (GB16297-1996); Exhaust-gas treatment amount can reach 50000m
3the scale of/h; Active carbon can regenerate use; Floor space is little; The equipment manufacturing cost of the air pollution whole synthesis process that Furniture manufacturing causes, maintenance cost, use cost reduce all greatly.
Preferably, air grid hurdle was provided with below described filter cotton layer.Tentatively to complete gas solid separation, avoid filter cotton layer clogging.Further, described air grid hurdle of crossing is provided with vibrating mechanism.Air grid hurdle was avoided to block.
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
Accompanying drawing explanation
Accompanying drawing is Furniture manufacturing air pollution treatment system overall structure principle schematic of the present invention.
Detailed description of the invention
See accompanying drawing, reflect a kind of concrete structure of the present invention, described Furniture manufacturing air pollution treatment system comprises dust negative pressure gathering system and lacquer spraying waste gas negative pressure gathering system, the dust exhaust outlet 4 of described dust negative pressure gathering system and the exhaust outlet 12 that sprays paint of lacquer spraying waste gas negative pressure gathering system are positioned at waste gas blending bin 1, and dust exhaust outlet 4 and the exhaust outlet 12 that sprays paint are oppositely arranged two kinds of waste gas are fully mixed; Below in described waste gas blending bin 1 is dust deposit chamber 13, dust exhaust outlet 4 and spray paint between exhaust outlet 12 and dust deposit chamber 13 and be provided with guiding cone 2, guiding cone 2 both sides are provided with two blocks of anti-wing plates 3 that backflow, anti-wing plate 3 root that backflows is fixed on waste gas blending bin 1 inwall, and the anti-wing plate 3 that backflows tilts downwardly guiding cone 2; Anti-backflowing between wing plate 3 and guiding cone 2 leaves gap, is convenient to fall in dust deposit chamber 13 in conjunction with the dust settling of paint particle.In described waste gas blending bin 1, top is provided with case exhaust outlet 14, and described case exhaust outlet 14 is provided with filter cotton layer 5, and filter cotton layer 5 adopts demountable structure, is convenient to change.Be provided with air grid hurdle 16 below described filter cotton layer 5, and crossed air grid hurdle 16 and be provided with vibrating mechanism (not shown in FIG.).Under the effect of the adjustable blower fan 6 of rotating speed, mix waste gas is sent into Water spray tower 7 by case exhaust outlet 14, the rotating speed of blower fan 6 can according to the gas solid separation process adjustment in waste gas blending bin 1, and the rotating speed reducing blower fan 6 when needed even stops being beneficial to solid particles sediment.Water spray tower 7 is provided with the water circulation system of circulating water pool 11 and circulating pump 10 formation.Water spray tower 7 exhaust outlet is communicated with activated carbon adsorption bed 8 by centrifugal blower 15, and activated carbon adsorption bed 8 exhaust outlet is communicated with chimney 9.
