Abstract
The utility model relates to a purifying device for spray painting fog which is aiming at solving the defects that filtering material used for the filtration of dry type spray painting chambers has easy blockage, low filtering efficiency, high consumption cost, etc. existing in the prior art. The utility model uses silicate porous material as the first stage filtering material in the process of filtering painting fog and uses saw dust made of woods as the second stage filtering material. The utility model is provided with a quick opened sealed door. Thus, the utility model has the advantages of convenient replacement, low cost, high reliability, simple and convenient repair, little blockage, large paint containing amount. The efficiency of purifying painting fog of the utility model is more than 99%.
Description
The utility model belongs to the sprayed paint fog purifier.
In spray painting operation, can produce a large amount of organic solvent gas that contains coating cloud, contain harmful substances such as toluene, dimethylbenzene in the organic solvent gas, contaminated environment not only, and also the harm operator's is healthy.Coating cloud purifies the paint spray booth, is the treatment facility in early stage that lacquer spraying waste gas purifies, because when using absorption method and Production by Catalytic Combustion Process to handle organic solvent gas, requires must reach more than 99% the purification efficiency of coating cloud.Simultaneously coating cloud purifies the paint spray booth and guarantees to spray paint the process equipment of quality.The paint spray booth is made up of suspended hood, paint spray booth, coating cloud clean room, blower fan etc., and according to the difference of coating cloud purification method, the paint spray booth is divided into two kinds of dry spray booth and wet type spray chambers substantially.
Dry spray booth purifies the mode of coating cloud: a baffle-type, be also referred to as baffle plate type or labyrinth baffle plate type, its purification mechanism be utilize particle in the coating cloud the inertia force collision on baffle plate and be captured.Two filtering types, filtering type are that coating cloud is contacted with filtrate, utilize the barrier effect of filtrate to remove coating cloud.Three baffle plates and filtration combined type.
Dry spray booth has simple in structure than wet type spray chamber, coated efficient height, coating cloud purify fully, and does not need to carry out advantage such as wastewater treatment, but because the filtrate that dry spray booth adopted fibrous substance normally, as glass fibre; Spongy material; Adopt at present the filter paper through special processing and manufacturing of external import in addition.But in practical operation, the filtrate that has blocks easily, need change filtrate continually.The media filtration efficient that has is low, does not reach the effect of purification.The filtrate consumption costs height that has.Therefore the use of dry spray booth is extensive not as wet type spray chamber.
The purpose of this utility model is to provide a kind of filter efficiency height, and cheap coating cloud purifies uses filtrate, and makes dry type coating cloud purification paint spray booth with this kind filtrate.
Solution is to utilize silicates porous material such as slag, last water stone, foamed brick or foam concrete as first order filtrate in the coating cloud filter process, and the sawdust of wood processing is as second level filtrate.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the front elevation that the dry type coating cloud purifies the paint spray booth.
Fig. 2 is the vertical view that the dry type coating cloud purifies the paint spray booth.
Fig. 3 is the rearview of coating cloud clean room.
Fig. 4 is the A-A cross-sectional view that the dry type coating cloud purifies paint spray booth's vertical view.
Fig. 1, shown in Figure 2, dry type coating cloud purify the paint spray booth and mainly are made up of paint spray booth (5) and coating cloud clean room (6).Workpiece to be sprayed paint is placed on the rotating disk (1) of paint spray booth (5) and goes up or be hung on the swivel hook (2), stirs handwheel (3) and can make rotating disk (1) rotation.The coating cloud that forms that sprays paint enters coating cloud clean room (6) by shutter (4) by paint spray booth (5) under the effect of blower fan, the route that coating cloud flows is referring to Fig. 4.Shutter (4) can play equal wind effect, and can cut and catch bigger coating cloud particle.
Fig. 3, shown in Figure 4, arrow is represented the coating cloud flow direction among the figure.In coating cloud clean room (6), the coating cloud air-flow is introduced into labyrinth type deflection plate (11), and under the effect of inertia force collision, the coating cloud particle that most of granularity is bigger is captured by deflection plate.The coating cloud air-flow that fully purifies does not enter by slag, goes up the first order filter material layer (7) that water stone, foamed brick or foam concrete are made, and above material porosity is big, not only is difficult for obstruction but also holds the lacquer amount big.The coating cloud air-flow that is effectively separated enters the second level filter material layer of being made by wood processing sawdust (8) at last, with remaining coating cloud particle by separating in the air-flow.Purified gas is discharged by discharge duct (13).
The resistance that this device produces when monitoring coating cloud by filter material layer with U type pipe pressure meter when the appearance lacquer amount of filtrate reaches capacity state, is opened and is opened hermatic door (9) soon, can change filtrate easily.The inner surface of opening hermatic door (9) soon is equipped with sealed rubber plate (10), open hermatic door (9) soon when closing, eight locking devices (12) extruding door is arranged, the sealed rubber plate (10) of opening hermatic door (9) inner surface soon can be abutted on the labyrinth type deflection plate (11), like this, sealed rubber plate (10) not only plays sealing function, constitutes the coating cloud gas channel with labyrinth type deflection plate (11) simultaneously.
For preventing that coating cloud from polluting baffle plate and equipment inwall, the body surface that passes through at coating cloud scribbles lubricating grease, when deposit thickens, can remove easily with instrument.Used filtrate is thrown away as rubbish, does not have the secondary pollution problem.
Because the utility model has adopted above design, makes the service efficiency of dry spray booth obviously improve.Compare with existing dry spray booth, the cost of filtrate reduces greatly, and filtrate be difficult for to block, and it is big to hold the lacquer amount, is provided with simultaneously to open hermatic door soon to change the filtrate mounting or dismounting easy.Use labyrinth type deflection plate and double-filtration to purify and can guarantee the coating cloud purification efficiency more than 99%, compare with existing wet type spray chamber, power consumption is low, and maintenance management is convenient, does not have secondary wastewater to handle problems.For except that the user who wants further to purify organic solvent gas behind the coating cloud, use this device will improve absorption and catalytic combustion purification efficiency, and can prolong the service life of adsorbent and catalyst in addition with absorption method and Production by Catalytic Combustion Process.
Sprayed paint fog purifies experimental data:
| Mg/m before coating cloud purifies 3 | Coating cloud purifies back mg/m 3 | Purification efficiency % |
| 270 | 2.0 | 99.3 |
| 198 | 1.7 | 99.1 |
| 165 | 1.5 | 99.0 |
The utility model can be widely used in the spraying coating process operation of various lacquers such as nitrate paint, amino lacquer, acrylic paint.From spraying method, in operations such as hand spray, electrostatic spraying, airless spraying, various spray paint streamline and manual touch-up paints.
Embodiment one, filter filtrate as the first order, the filtrate that filters as the second level with the sawdust of wood processing with the boiler slag after the screening.
Embodiment two, filter filtrate as the first order, with the sawdust of wood processing filtrate as second level filtration with the last water stone after the processing.
