Description

Cleaner-type air filtration system for cleansing and freeze-free air purification {AIR FILTER OF AUTOMATIC CLEAN WASHING}

The present invention relates to a self-cleaning air filtration device that can easily purify the air for four seasons by preventing freezing without using a detergent,

More specifically, foreign matter such as dust collected in the filter installed inside the air filter is first sprayed by using high temperature water to increase the cleaning power, and then second, a mixed fluid mixed with water and compressed air is sprayed. In order to prevent freezing of the water remaining in the filter after regeneration of the filter in winter, the air generated at the third temperature is sprayed onto the cleaned filter to remove the remaining water to prevent freezing. It helps to remove dispersed scattering and improve the filtration performance by maximizing the filtration power of the filter and at the same time to reduce the amount of filtered water. To maximize the satisfaction and reliability of the air filtration system using high temperature water and high temperature air. Relates to the automatic three orthopedic air filtration devices for purification of non-detergent and freezing air.

Generally, industrial facilities such as subways, underground malls and factories, department stores, hospitals, and other business buildings are equipped with air purifiers to remove oil dust, moisture, and dust generated by the facilities and external inflows. It is being used.

As such, the air purifier is essentially provided with a plurality of air filters for collecting large dust or fine dusts, and the air filters may be washed or replaced from time to time so as to keep the dust collection efficiency at a constant state. Should be managed.

Conventionally, the cleaning method of the filter of the air purifier is a method of separating and cleaning the air filter from the housing, or replacing the air filter itself.

However, the air purifier has a problem that the amount of water used is low or the washing ability is low, and there are problems such as waste water treatment and freezing or it is not available in a limited space. Or it was cleaned by spraying the nozzle from the back, but this is only 100% of the filter's total surface and thickness due to oblique and filter structure obstacles to pass the inclined surface 100% through the 50mm thick air filter. And the rest flows downward along the inclined surface due to inertia, and as the use and cleaning time elapses, the upper part, which is part of the filter, is used without being cleaned and the performance of the entire filter surface is lost. It was difficult to continuously maintain the original performance of the filter.

The method of cleaning the front and rear surfaces separately includes a phenomenon in which contaminants accumulate inside the filter as the water is sprayed in the direction collected by the filter, large consumption of water, addition of additional equipment, and insufficient cleaning ability. There is a problem.

In order to solve the above problems, the technology for 'water and wastewater-saving automatic cleaning type air filtration device' of Korean Utility Model Registration No. 314830 (registered on May 16, 2003) has been devised. .

In order to remove the foreign matter collected in the filter, it is first applied with water and then used to generate a mixed fluid mixed with water and air at a constant ratio, and at this time, since cleaning is performed using a detergent during washing, sewage after washing occurs. In addition, there is a problem in that the installation cost is increased because a separate sewage purification device is required to purify the sewage, and in the case of washing, water cannot be freely washed at the same time as the efficiency of use is limited because the side wall of the air filter is not cleaned at all. Due to the problem that can not be used properly there is a problem that can only be used in a limited season.

Therefore, due to the above problems, the conventional air filtration apparatus has a limited efficiency to some extent, and the environmental pollution and economic loss are aggravated by the use of mucus (detergent) and excessive water, On the whole, there is always a problem that the satisfaction and reliability of the use is deteriorated.

The present invention was created to solve all the problems of the prior art as described above has the following object.
