Description

The automotive painting booth combined with wet scrubber}

The present invention relates to a painting booth for automobiles combined with a wet dust collector, and more particularly, by filtering paint dust and odors generated inside the painting booth by contacting it with water to filter foreign substances or It relates to a painting booth for automobiles combined with a wet dust collector capable of removing dust, dust, odor, and the like.

In general, when you buy a car and drive it, there are many cases where a new paint is applied to a part of the body of the car due to various factors. At this time, in order to repaint the body of the vehicle with paint, the painting is performed at a painting booth accessible to the vehicle. In addition, when a new paint is applied to the body of the vehicle, a heat treatment device for drying the paint within a short time is used.

When painting a vehicle by spraying paint in the state of fine droplets, a significant portion of the sprayed paint is spread in the air instead of being applied to the surface of the car. In this way, the paint spread in the air spreads and pollutes the surrounding air. A sealed painting booth is installed to prevent painting, and the vehicle, which is the object to be painted, is placed inside and painting is performed.

Meanwhile, the dust collector is divided into two types, a dry type and a wet type, and the dry type may be further divided into an electric dust collection type and a filter filtration type. The filter filtration type has a configuration in which air flows through the filters so that various particulates such as dust are filtered by the filter, but there is a disadvantage in that maintenance costs such as periodic filter replacement occur.

Since the electrostatic precipitation type does not use a filter, there is an advantage that the filter does not need to be replaced, but when dust accumulates on the dust collecting plate, the dust removal ability is weakened and the purification ability is deteriorated, so it is vulnerable to gas or odor removal other than dust. There are disadvantages.

On the other hand, the wet dust collector is a method of purifying by depositing or dissolving pollutants such as dust or gas in the process by contacting the sucked air with a wet cleaning agent such as water. Since there are advantages such as, its use is gradually increasing in recent years.

Specifically, paint dust, dust, etc. are primarily removed by the spray nozzle 230 disposed on the upper part, and the paint dust, dust, etc. are secondary removed by the spray nozzle 230 disposed on the lower part. Paint dust and dust are primarily collected and removed through the spray nozzle 230 disposed on the upper part, and in the area where the spray range of the spray nozzle 230 disposed on the lower side and the spray nozzle 230 disposed on the upper part overlap More strongly, paint dust and dirt are secondarily decomposed and removed. In addition, water and chemicals are sprayed together through the spray nozzle 230 to remove odors and the like.

Water collecting contaminants is collected by falling on the lower part of the nozzle receiving space 211 and the lower part of the blowing space 212, and the polluted water is discharged through the discharge hole 240 formed in the side of the main body 210 to be removed. 1 It moves along the pipe 251.

Contaminated water flowing in the first pipe 251 is transferred to the filter device 270 according to the operation of the first circulation pump 252 , and the first pipe 251 is formed in an L-shape, so that the rising part and the falling part are formed in the L-shape. formed to exist. Contaminated water is transported along the rising part of the first pipe 251 by the first circulation pump 252, and the polluted water is again transported along the falling part of the first pipe 251 so as to have a free fall, so that the movement of potential energy It is configured to pass through the first pipe 251 without clogging according to the energy conversion. When the shape of the first pipe 251 is --shaped, it is easier to transport the contaminated water when the shape of the r-shaped, and the water can flow without clogging the pipe.

Contaminated water passing through the first pipe 251 is filtered by the filter device 270 , and the filtered water is again transferred along the second pipe 261 by the second circulation pump 262 , and the second pipe The filtered water passing through 261 is transferred into the nozzle accommodation space 211 and is sprayed again through the plurality of injection nozzles 230 . After the contaminated water is filtered through this series of processes, the filtered water is repeatedly supplied to the spray nozzle 230 .

The second pipe 261 is also formed in a L-shape, so that when the water filtered by the second circulation pump 262 flows along the second pipe 261, the fall is used to convert the potential energy into kinetic energy without clogging.
