Description

AUTO WASHING SYSTEM OF AIR FILTER}

The present invention relates to an air filter automatic cleaning device, and more specifically, to automatically clean the air filter (AIR FILTER) installed for the indoor air cleaning of large buildings such as subway, commercial buildings, hospitals, etc. It is about reproducing and using it semi-permanently.

In general, to manage micro-pollutants, humidity control, and air pollution level below indoor facilities in large buildings such as subways, commercial buildings, large department stores, hospitals, and other business buildings where air is introduced. For the outside air flowing in from outside, pre-filter, medium filter, high-grade type (HEPA or ULPAFILTER) and especially odor removal filter are arranged in series by efficiency in order to remove a lot of pollutants or odor. The air is purified and introduced to meet the requirements of the room.

However, the air filter is trapped by the foreign matter on the surface due to the use of a certain time, the air purification efficiency is lowered if the collection amount gradually increased.

Therefore, in order to continuously purify the air and introduce it into the room, the air filter must be replaced or cleaned immediately when the range of the dust collecting efficiency of the air filter, that is, the collection amount, is exceeded.

On the other hand, the conventional air filter is an exchange type that separates and discards the disposable filter when the collection amount is exceeded, or an auto gulter type that winds up at a predetermined interval when the air filter is wound on the drum, and an automatic regeneration type that is sucked by a vacuum inhaler. This filter has been used mainly, and an air filter equipped with a water spray cleaner in consideration of the cost and maintenance aspects of the air filter has also been proposed.

The conventional air filter exchange type and automatic winding type has the disadvantage that industrial waste is generated, replacement labor costs are increased, the air filter equipped with a water spray cleaning device is the header of the spray nozzle for spraying water up, down or As the transfer device is used to move left and right, a separate transfer device requires a device and a control unit to switch the power and the direction of the transfer device, and there is a defect in the device and the control unit. Since electric devices such as electric motors coexist, there is a problem that a risk of an electric leakage may exist and the water dropping device may be in a state in which a pressure drop due to water leakage and a perfect cleaning operation cannot be performed.

Therefore, there is a need for a cleaning device for an air filter to compensate for the above problems.

The present invention has been made to effectively solve the above problems, the air filter is sprayed through the rotary spray nozzle pipe rotated by the pressure and its own weight while the water supplied through the main pipe and the distribution pipe is injected without a separate mechanism It is designed to clean the contaminants such as dust collected on the surface of the car. In addition, it is possible to perform the cleaning work while the blower is operating. It is.

The object of the present invention is to provide a air filter automatic cleaning device to maintain a comfortable environment by ensuring that the maintenance cost of the facility is relatively reduced, the air filter can be surely made.
