Description

air purification system

The present invention relates to an air purification system, and more particularly, to an air purification system that can be installed on a wall to quickly purify ambient air and facilitate maintenance.

An air purifier is a device that removes fine dust in the air by forcing the surrounding air to pass through a filter. It includes a filter that filters out fine dust in the air. Such an air purifier filters and removes fine dust in the air by a fan motor forcing air through the filter, and the air from which fine dust has been removed is mixed with ambient air to lower the total concentration of fine dust, and repeating this process Fine dust in the surrounding air is gradually removed.

However, since the air purifier has a mechanism to remove fine dust in the process of forcibly passing the filter after inhaling the air, it takes a lot of time to purify the air from a relatively long distance, and Air purification was not performed.

In addition, since air purification is accomplished by the filter adsorbing fine dust in the air, it is necessary to change the filter frequently in spaces where a lot of fine dust is generated, such as cafes, restaurants, and offices shared by many people. If the filter heavily contaminated with fine dust is used without replacing the filter, the surrounding air is contaminated by the fine dust separated from the filter.

In addition, since the air purifying capacity is dependent on the filter, in reality, it is only less than 10 pyeong, and accordingly, the maintenance burden of operating several air purifiers in a large space occurred.

And since the air purifier has a small air purifying capacity, in reality, the residence time of fine dust in the space becomes longer, and accordingly, the fine dust in a space far from the air purifier accumulates on the floor and corners of the space, or a lot of static electricity is generated. There was a problem that it was adsorbed to electronic devices, and thus dust was accumulated, resulting in an unsanitary environment.

The present invention was created to solve the above problems, and it is possible to quickly purify the air in a large space where a lot of fine dust is generated, and to facilitate maintenance by not replacing the filter for filtering fine dust. An object of the present invention is to provide an air purification system.

In addition, when the wall suction unit is composed of a plurality of first, second, and third suction walls 100, 100', and 100" that independently suction the surrounding air, the size of the space is very large by varying the number of suction walls. However, rapid suction is possible.

In addition, since the air purifier 400 adsorbs and removes fine dust by a wet filter method using water, there is no need to replace a filter like a conventional air purifier, so maintenance is easy.

And since the intake fan 200 and the air purifier 400 are located in the outdoor space O, noise or electromagnetic waves do not flow into the indoor space I while the air purifying system is running, so that a quiet environment can be maintained. .

Although the present invention has been described with reference to one embodiment shown in the drawings, which is only exemplary, those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom.
