Description

Wet and dry compound air cleaner with self cleaning function {AIR CLEANER WITH SELF CLEANING FUNCTION}

The present invention relates to an air cleaner having a self-cleaning function, and more particularly, to achieve air cleaning by using a wet scrubber (particulate matter, gaseous material, pretreatment removal function) and a washable filter by spray spraying. In addition, contaminated filtration filter for a long time use relates to an air cleaner having a self-cleaning function that can be cleaned by the angle change of the spray spray nozzle.

In general, the filtration filter is a high-density filter with a dust collecting efficiency of 80% to 99.97% for 0.3 µm particles, and is effective for collecting small particles. However, if the dust particles deposited on the filter medium are extended for a long period of time, the pressure loss is increased, the air volume is reduced, and the purification capacity of the air cleaner is reduced. You must replace it.

Therefore, there is a disadvantage in that it causes the environmental pollution as well as the high cost caused by the replacement and disposal of the periodic filter. In general, air cleaners use a pretreatment filter and a neutral filter to increase dust collection capacity and filtration filter life. However, it is inconvenient to clean and replace each filter from time to time.

In addition, the conventional wet scrubber type air cleaning method inerts collisions, direct hops, and diffusion by floating dust particles in the air in contact with droplets, liquid membranes, and bubbles generated by spraying water on the contaminated air. It removes dust particles.

This method has a simple structure and the maintenance cost is low because only the used cleaning water needs to be replaced without the need to clean or replace a separate filter. However, it is possible to treat only relatively large particles and has low dust collection efficiency. There are disadvantages.

The present invention devised an air cleaner using a combination of a wet scrubber with a shearable filter to solve the problems described above, in particular, in the present invention by adjusting the injection direction of the wet scrubber to automatically clean the filter filter Its purpose is to enable continuous use of high-efficiency filtered filter air cleaners without additional management and cost. In addition, the bacteria propagation problem of the filter occurring in the wet cleaning process is suppressed by mounting a UV photocatalyst lamp.

In order to achieve the above object, the present invention uses a filter or a hepa filter washable filter, and a wet scrubber is used as a pretreatment filter to improve efficiency. It is possible to control the spray angle by rotating the water jet hole of the wet scrubber, and when the filter is contaminated, the spray angle is automatically adjusted to clean the filter.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings for a purifier according to the present invention.

FIG. La shows the concept of an air purifier according to the present invention, in which contaminated air sucked into the air purifier is sprayed at the jet hole 2a of the wet scrubber 2 in the course of passing through the air passage A. 3) It collects dust (fine dust), etc. contained in the air primarily by the moisture, and falls down with the falling water. The falling water is circulated along the pipe pipe 5 by the pump 4.

Such a spray nozzle 2 is exemplarily illustrated in FIGS. 3 to 5, wherein the wet scrubber 2 has a predetermined length, and forms an empty hollow inside the pump 4. The washing water being pumped is introduced, and the ejection holes 2a are concentrated on one side.

The front end of the wet scrubber 2 is blocked, and an inlet coupler 2b into which the washing water introduced by the pump 4 flows is assembled at the rear end thereof, and an inlet coupler 2b and a wet scrubber 2 are assembled. ) Is assembled by a sealing member (not shown) for watertight action. The inlet coupler (2b) is a watertight action of the sealing member by the fastening force when the screw assembly between the wet scrubber (2) and the knob (2c), but the inlet coupler (2b) is rotatable separately from the wet scrubber (2) The knob 2c and the wet scrubber 2 are assembled to pivot together.

Reference numeral 2d is a fastening portion for attaching the wet scrubber 2 to the wall surface constituting the air passage of the cleaner.

Therefore, the wet scrubber 2 is rotated together with the wet scrubber 2 when the knob 2c is rotated. Therefore, when the knob 2c is rotated clockwise or counterclockwise, the ejection direction of the ejection hole 2a formed on the surface of the wet scrubber 2 is selectively directed toward the filtration filter 1 or the air passage A. Can be switched.

Therefore, when water is sprayed (3) into the air passage (A) by the blowing hole (2a) of the wet scrubber (2), water sprayed with foreign matter (dust), etc. in the air flowing into the air passage (A) They adhere to the particles and fall down, and bacteria or harmful elements are sterilized or sterilized in the process of passing through the UV lamp 6 installed in front of the filter 1, and again in the process of passing through the filter 1 Fine dust and harmful elements are filtered out, leaving only clean air.

The above-described filtration filter 1 generally uses a hepa filter using a charged nonwoven fabric or the like, but is configured to function as the filtration filter 1 by being installed at the rear end of the wet scrubber 2 using an electrostatic precipitating method. do. In addition, a hepa filter and a filter using an electrostatic precipitating method may be used in combination to be used as the filtration filter 1.

On the other hand, by using the electrostatic spray when using the wet scrubber (2), by increasing the amount of dust and gas adhering to the water particles, it was to increase the dust collection and gas removal rate.

Figure 1b is an exemplary view showing a case in which the intake air of the air cleaner is moved from the bottom to the top.

2A and 2B show the concept of cleaning the filtration filter 1 by rotating the wet scrubber 2 to change the injection direction of the ejection hole. The sprayed droplets flow together with the water droplets to the bottom of the air passage along with the dust particles deposited on the filter, thereby reducing the amount of dust particles deposited on the filter medium 1.

Therefore, the user replaces only the water used in the wet scrubber on a regular basis, thereby continuously maintaining and managing the high-performance filtration filter type air cleaning function.

In addition, the UV lamp 6 is partially coated with a photocatalytic material (titanium dioxide) on the surface thereof to add bactericidal and deodorizing effects by radicals such as OH, and to propagate bacteria by wet (spray and washing hepa filter unit). And by further providing a odor suppression function can further improve the clean function.

As described above, by adjusting the direction of the water jet hole of the wet scrubber to wash the filtration filter with water, it is possible to continuously use the highly efficient filtration filter type air cleaner without additional management and cost. In addition, the reduction of waste has the effect of developing environmentally friendly air cleaner.

Therefore, the spray nozzle of the conventional wet air cleaner can be applied to dry filter cleaning while providing a high-efficiency air cleaning function in parallel with wet and dry to solve the problem of maintenance.
