Background
Through rapid economic growth, urbanization and industrialization, the pollution problems of atmosphere, water quality, waste and the like become social problems due to deepening of environmental pollution in China.
Particularly, the harmful effect on human bodies and animals and plants is not only its own harmful effect due to dust or gas discharged into the atmosphere, but also its influence is larger as the particles become smaller by the harmful gas coexisting with the harmful gas spreading to the larger harmful effect. In addition, fine dust is not easily dropped on the ground and floats in the atmosphere for a long time, thus causing visual disorders, pneumoconiosis, and haze.
In particular, paint dust is generated in a large amount during a painting operation, and the paint dust scatters to contaminate the surrounding environment, and Volatile Organic Compounds (VOCs) are generated in a large amount from the paint, and the Volatile Organic Compounds are all Organic Compounds that increase the surface ozone concentration by reacting with nitrogen oxides due to sunlight in the atmosphere.
To remove such paint dust, dust collecting devices have been developed.
As a technique for removing such paint dust, korean registered patent No. 10-135083 (dust collecting device for UV paint dust) and korean registered patent No. 10-1525774 (dust removing device for paint) are disclosed.

The agitator 52 is formed in a rectangular parallelepiped shape having open upper and lower ends and a hollow interior, so that a plurality of trap plates 52a are vertically arranged in a module case 51 while being connected to each other, a zigzag shape is vertically arranged at the inner lower end, a water inflow hole WH is provided at the central portion side, and water is mixed with contaminated air supplied from the air inflow port 12 of the cartridge 10, thereby removing the paint and contaminants at a time.
The water baffles 54 are horizontally spaced apart from each other from the central portion of the module case 51, that is, two plates are spaced apart to provide a space to enable water to be stored therein so as to supply water to the inside of the pulsator 52.
The water tank 55 is provided at the lower end of the first space portion S1 in the box body 10, spaced apart from the lower end of the module case 51, and collects water falling from the pulsator 52.
A sump 56 is provided at one side lower end of the case 10 to supply water to the inside of the water guard 54 through the water inlet 51a of the module case 51, thereby supplying water to the water inflow hole WH of each pulsator 52.

The contaminated air moves from the upper portion to the lower portion of the agitator 52, and is mixed with the water flowing in through the water inflow hole WH, and the dust and the water move along the zigzag collecting plate 52a provided at the inner lower end of the agitator 52, so that the residence time increases, and the dust and the water are further mixed and then fall into the water tank 55.
On the other hand, about 80% or more of the dust is removed at the first time by the agitator 52, and about 95% or more of the dust is removed at the second time when the primarily purified air staying in the first space section S1 passes through the rotating dust collecting rotary filter 60 and flows into the inside thereof.
Subsequently, the secondarily purified air moves to the second space portion S2 through the upper portion of the rotary dust collecting filter 60, and then moves to the third space portion S3 through the fixed dust collecting filter 70 provided on the partition wall 11. At this time, about 98% or more of the dust is removed three times when the air purified twice passes through the fixed dust collecting filter 70.
The third purified air in the third space portion S3 is discharged to the atmosphere through the air outlet 13 of the box 10, the discharge duct 30, and the blower 40.
However, in the conventional dust collecting device for UV paint dust, the paint is dry-treated when passing through the two dust collecting filters, and in the case of paint dust, since the paint dust has a high viscosity, there is a problem that the paint dust cannot be treated only by the filters.

The centrifugal separation cylinder 230 rotates while spraying water on the surface, and rotates in a state where a film is formed by surface tension, and only dust and contaminants of the UV paint having a certain size (for example, 2mm) or less pass through the plurality of holes 231 of the sieve plate 233, and the dust and contaminants of the UV paint exceeding the certain size drop together with the water, and freely drop to the collection groove 163 of the water storage tank 160 through the discharge pipe 220 to be collected. At this time, about 80% of dust and contaminants of the UV paint are removed in the primary centrifugal separation module 120.
The contaminated air passing through the plurality of holes 231 of the screen plate 233 of the centrifugal separation cylinder 230 is pumped to the secondary centrifugal separation module 130 through the air discharge holes 213 formed at both side surfaces of the casing 210, and through the above process, only the dust and the contaminants of the UV paint having a certain size (for example, 1mm) or less pass, and the dust and the contaminants of the UV paint exceeding the certain size drop together with water, and are freely dropped to the collection tank 163 of the water storage tank 160 through the discharge duct 220 to be collected. At this time, about 15% of the dust and contaminants of the UV paint are removed in the secondary centrifugal separation module 130.
Then, the contaminated air passing through the plurality of holes 231 of the screen plate 233 of the centrifugal separation cylinder 230 is pressure-fed to the third centrifugal separation module 140 through the air discharge holes 213 formed at both side surfaces of the casing 210, and through the above-described process again, only the dust and the contaminants of the UV paint having a certain size (for example, 0.5mm) or less pass, and the dust and the contaminants of the UV paint exceeding the certain size drop together with water, and freely drop to the collection tank 163 of the water storage tank 160 through the discharge duct 220 to be collected.
In addition, the air discharged through the air discharge holes 213 formed on both side surfaces of the case 210 of the tertiary centrifugal separation module 140 is discharged to the atmosphere through the air discharge port 113 of the case 110 after removing dust and contaminants of the UV paint of fine particles through the glass filter 150. At this time, about 3% of the dust and contaminants of the UV paint are removed by the third centrifugal separation module 140, and less than 1% of the dust is discharged by filtering 2% or less of the dust with the glass filter 150.
On the other hand, the water dropped to the collecting tank 163 precipitates the dust and the contaminated substances of the UV paint due to the difference in specific gravity, and only the supernatant water is discharged to the first filtering tank 164 through the first water discharge port 167, the water is discharged to the second filtering tank 165 through the second water discharge port 168 formed at the lower end in the first filtering tank 164 in order to prevent the foam generated in the collecting tank 163 from being discharged, and only the supernatant water is discharged to the storage tank 166 through the third water discharge port 169 while the dust and the contaminated substances of the UV paint are precipitated in the second filtering tank 165 due to the difference in specific gravity.
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the invention is not limited to the particular forms disclosed, but it is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
