Description

Wet Scrubber {Wet scrubber}

The present invention relates to a dust collector, and more particularly, by contaminating the contaminated air or exhaust gas with water and filtering to remove foreign substances or dust contained in the contaminated air and exhaust gas, the direction of water injection is 360 degrees. It is possible to operate more efficiently and economically by improving economical efficiency and technology to discharge fresh purified air while drying outside by discharging the purified air containing moisture before being discharged at the same time. It relates to a wet dust collector.

In general, a dust collector (集塵 器) is a device that cleans the air containing pollutants such as fine dust, various harmful gases, various bacteria, mold and viruses, and then discharges clean air.

These dust collectors function to provide a pleasant and healthy environment through air purification as well as removing various odors and removing fine particles such as mites, pollen and pet hair.

In general, dust collectors are classified into two types, dry and wet, and dry may be further divided into electric dust collection and filter filtration.

The filter filtration type has a configuration in which various particles such as dust are filtered by the filter by flowing air through the filter, and there is a disadvantage in that maintenance costs such as the need to periodically change the filter are generated.

The electrostatic precipitating type has the advantage of not having to replace the filter because it does not use a filter, but when the dust is accumulated on the dust collecting plate, the ability to remove dust is weakened and the purification ability is reduced, and thus it is vulnerable to the removal of gas or odor other than dust. There are disadvantages.

On the other hand, a wet dust collector is a method of contacting wet air with a wet purifier such as water, thereby purifying or dissolving contaminants such as dust and gas in the process, thereby eliminating the need to change filters and reducing noise. In recent years, its use is gradually increasing.

Looking at the prior art for such a wet dust collector,

In the Republic of Korea Patent Publication No. 10-2012-0013771 is sprayed with fine water droplets to remove the dust first, and the unremoved dust is passed through the water again to remove the second and finally to filter the dust completely through a multi-stage filter. A wet scrubber with improved purification performance is disclosed.

In addition, the Republic of Korea Patent Publication No. 10-2011-0108971, the air is introduced into the inside, the filter unit for filtering the introduced air is provided inside the filter dust collector for filtration and discharge the introduced air to the filter unit, the filter dust collector inside Disclosed is a dust collector capable of simultaneously treating dust and fine dust and sulfur oxides in combustion air with ammonium sulfate and filtering them by the filtration unit, including an ammonia injection device for injecting ammonia into the air introduced into the air.

However, such a wet dust collector is usually configured to have a large fixed structure, such that it is impossible to move and place it to a necessary place, and there is a problem that it is cumbersome to replace the wet purifier or to remove the precipitate.

In addition, when spraying water or liquid to remove the contaminants there is a problem that the contaminants are not effectively removed.

On the other hand, in the case of the wet dust collector, while the air flows by using the vortex of the water filled inside the main body of the dust collector, the various foreign substances contained in the air is filtered in the water and discharged, if the water level is too high at this time When the water is over to the blower side causes a blower function deterioration, and if the water level is too low, the filtration efficiency is lowered without forming a vortex.

In particular, there is a problem in the effective removal of contaminants as the direction of water or liquid to be sprayed is simply sprayed uniformly downward.

Therefore, by constructing a small wet dust collector to solve such an overall problem, it is possible to arrange its movement in the place where the dust collector is required, and further, to freely spray the direction of water or liquid to be sprayed in multiple directions, There is a need for a method for efficient removal and easy replacement of wet purifiers or removal of sediment.
