Abstract
The utility model discloses a purifying system of organic exhaust gas containing paint mist, comprising a mixer with a channel for passing the organic exhaust gas containing paint mist, a powder storage box containing powder, communicating with the inlet of the channel of the mixer and a filter communicating with the outlet of the channel for separating the coagulum generated by the combination of the powder and the paint mist from the gaseous organic exhaust gas. The utility model not only overcomes blockage of the existing purifying device, but also has simple setting, easy operation and low cost of running, suitable for treatment of organic exhaust gas generated by various organic paint.
Description
Technical field
The utility model relates to a kind of cleaning system of exhaust organic gas containing paint mist.
Background technology
Paint is a kind of as decorating or protect outer field liquid mixture.Coating cloud is the paint winding-up of air by compression and a kind of vaporific form of forming in spraying process, it is a kind of disperse system in air, be irregular and the colloidal sol body of uneven compound movement, when being in lacquer thing state, paint can stick on the required product processed surface effectively.Usually, in the paint spraying process, the spray paint of 1kg paint adhesion on product is at most 75%～85%, and 15%～25% paint mist is in addition being carried the organic solvent that also is not evaporated completely secretly along with pump-line is discharged.This exhaust organic gas containing paint mist will bring great pollution to surrounding enviroment as not carrying out purification treatment.
In the prior art, the processing method of exhaust organic gas containing paint mist mainly contains venturi coating cloud filter paper or glass pad absorption method, and water curtain sprinkling or scrubbing tower absorption process are to wherein volatile and carry out charcoal absorption or Production by Catalytic Combustion Process etc. with the incompatible organic solvent of water.Though these methods can be carried out to a certain degree purification to exhaust organic gas containing paint mist.Yet which kind of method all exists the big and cleaning system of material consumption easily because of the solid particle in the coating cloud and sticky matter blocking problem to take place.
The Chinese invention patent application of application number 200810243790.0 discloses a kind of paint mist purifying means, this device mainly comprises atomizing absorber, gas-liquid separator, whizzer and the filter that is communicated with successively, and the operation principle of this device can be referring to the 4th section of its Instructions Page 2.The purification efficiency of this device can reach more than 95%, yet, this device does not still thoroughly solve the coating cloud blocking problem, for example in whizzer, though cohesion takes place and is got rid of into the casing inwall by centrifugal force in coating cloud, yet because coating cloud particle surface wettability and adhesiveness, it is easy to stick on the tube wall of leak oil line, gets off for a long time and will result in blockage.In addition, the equipment input of this device is bigger, and energy consumption is higher.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of cleaning system of improved exhaust organic gas containing paint mist is provided.
For solving above technical problem, the utility model adopts following technical scheme:
A kind of cleaning system of exhaust organic gas containing paint mist, described cleaning system comprises: have the passage that flows through for exhaust organic gas containing paint mist blender, in powder and the Chu Fenxiang that is connected with the arrival end of the described passage of blender are housed, being connected with the port of export of passage is used for air exhauster that filter, the organic solvent adsorbent equipment that is connected with filter and suction inlet that powder and coating cloud separate with the organic exhaust gas of gaseous state in conjunction with the coagulum that produces are connected with the organic solvent adsorbent equipment.
According to a preferred aspect of the present utility model, described passage is tubaeform that the direction towards outlet narrows down gradually from inlet.
According to the utility model, the organic solvent adsorbent equipment can be active carbon adsorber or absorption tower.Those skilled in the art should select and determines concrete adsorbent equipment and parameter according to the solvent of concrete paint.
According to further embodiment of the present utility model: cleaning system also comprises carrying out dry drier through the isolated coagulum of filter and dried coagulum being refined into the device for thinning that powder is handled.Through super-dry and the coagulum after being refined into powder be added to the agent for capturing that is used as coating cloud in the storage powder case again, when realizing zero-emission, reduce cost.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
When utilizing the utility model to carry out the purified treatment of exhaust organic gas containing paint mist, exhaust organic gas containing paint mist mixes in the passage of blender with the powder of motion, the coating cloud that powder can be caught in the waste gas effectively forms coagulum, the viscosity of coagulum is compared coating cloud and is all greatly reduced with wetability, avoided because the blockage problem of the cleaning system that coating cloud causes.That the utility model is provided with is simple, easy to operate, energy consumption is little, is suitable for the purified treatment of the exhaust organic gas containing paint mist that various organic paints sprayings produce.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment:
Fig. 1 is a schematic diagram of the present utility model;
Wherein: 1, blender; 10, passage; 2, Chu Fenxiang; 3, filter; 4, organic solvent adsorbent equipment; 5, air exhauster; 6, drier; 7, device for thinning.
The specific embodiment
As shown in Figure 1, according to the cleaning system of present embodiment mainly comprise blender 1 with path 10, be connected with the inlet of path 10 and in the air exhauster 5 that the storage powder case 2 of pulverized limestone, the filter 3 that is connected with the outlet of path 10, the organic solvent adsorbent equipment 4 that is connected with filter 3, suction inlet are connected with organic solvent adsorbent equipment 4 is housed.The path 10 of blender 1 is tubaeform that the direction towards outlet narrows down gradually from inlet, under the effect of air exhauster 5, pulverized limestone in the storage powder case 2 fully mixes in path 10 with the organic exhaust gas that contains coating cloud with certain speed, during to the exit of path 10, nearly all coating cloud is all caught by pulverized limestone and is formed dry and the bigger coagulum of particle, this coagulum further enters in the filter 3, filter 3 is held back coagulum, only allows the organic exhaust gas of gaseous state pass through in the organic solvent adsorbent equipment 4.Organic solvent absorption plant 4 can make the gas of discharging from the outlet of air exhauster 5 can reach national specified discharge standard the organic solvent molecule absorption in the organic exhaust gas.In this example, organic solvent adsorbent equipment 4 is an active carbon adsorber.
In addition, cleaning system comprises that also the coagulum that filter 3 is retained down carries out dry drier 6 and the device for thinning 7 that becomes powder with thinning processing in this example, so, after coagulum drying and the refinement, can loop back in the storage powder case 2, as the agent for capturing of coating cloud.
To sum up, the utility model has not only overcome the blockage problem of existing purifier, and be provided with simple, easy and simple to handle, operating cost is low, is applicable to the improvement of the organic exhaust gas that the spraying of various organic paints produces.
More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spiritual essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
