Description

Wet air cleaner

More particularly, the present invention relates to a wet type air washer, and more particularly, to a wet type air washer, and more particularly, to a wet type air washer having a water layer of water, a salt solution, a base solution and an organic acid solution, , The pollutant is adhered to the water film of the washing liquid, and is adsorbed and dissolved, thereby making it possible to remove pollutants. By using the food additive salt, base and organic acid for antibacterial and eradication Which is free from the controversy of human health, and further facilitates maintenance and internal cleaning.

As we all know, the desire for clean and safe air is increasing due to the increase of ultrafine dust with the dust. Nowadays, air purifier and air conditioner filter are controversial about harmful substances after humidifier disinfectant.

The recognition that antibacterial agents and antibacterial agents used in air purifiers and air conditioners are the main cause of harmful substances has been spreading, and antibacterial function and antibacterial function as well as air pollutant removal function have become important.
In particular, water is the cause of the use of harmful substances as antibacterial and antiseptic agents in HEPA filters used in air cleaners and air conditioners. Bacteria and fungi trapped in the HEPA filter are proliferated by the water, causing air pollution or odor.

That is, it is required to provide a safe and comfortable air by the antibacterial function and the antibacterial function using the natural substance and the natural principle which are not harmful to human body.

On the other hand, the distribution of solid particles in the air varies from visible to invisible, ranging from 0.001 μm to 500 μm. Fine dust particles are particulate air pollutants with a diameter of 10 μm or less, , And a diameter of 0.1 탆 or less is called a super fine dust (PM 0.1).

Sub-fine particles are small in size and do not get caught in the nasal mucosa, mouth, or bronchus. If they continue to be inhaled, they cause various respiratory diseases such as asthma.

An air washer, which purifies the air using water, constitutes a part of the air conditioner. It sucks contaminated air into the machine and sprays cold water and hot water in the form of droplets of water, The pollutants are attached and removed, and the soluble gas is melted and removed together.

A scrubber, a packing tower, and a spray tower are provided in the form of a dust collecting device. Since the air can be cleaned by removing contaminants and the humidity can be increased or decreased at the same time, it is widely used in industry However, it was rarely used for office or home use.

For this reason, small, light and easy-to-handle air cleaners have been used mainly for office and home use.

The air purification method of the air cleaner is largely divided into the following three stages: using a fan, a filter made of fabric, paper, glass fiber, etc., a high efficiency particulate air filter made by compressing fine nonwoven fabric or glass fiber, , And an electrostatic dust collecting type in which a high voltage of several thousand volts is applied to polluted air, and the polluted particles are attracted to (+) charge and attached to a dust collecting plate to which electrons are charged.

Air purifier filters are divided into 3 ~ 4 types, and they are cleaned with a three-stage filter such as a pre-filter that filters large dust, a hepa filter that filters yellow dust and fine dust, and a deodorant filter that removes odors in the air. Although the HEPA filter is expensive, it is difficult to remove superfine dust smaller than 0.1 mu m.

When using a filter-type air cleaner, the filter must be cleaned frequently or the filter replacement period must be strictly observed to prevent air contamination of the filter.

Electric dust collecting type air cleaner has advantages such as power consumption, noise and maintenance cost, but it has disadvantages such as lower dust collection efficiency, generation of ozone or nitrogen oxide, and easy cleaning of the inside of the body.

In view of this point, Patent No. 10-0601029 has been filed for a dry and wet composite air purifier having a self-cleaning function.

This dry and wet composite air purifier with self-cleaning function can filter polluted air containing wet spray droplets with a HEPA filter to increase the antibacterial effect with the dust collection efficiency and the UV lamp. However, when the filtration pore is blocked by water droplets, As the pressure loss is increased, the air purification ability is reduced. In the UV irradiation path, the antibacterial function is insufficient in the inside of the HEPA filter and in the inside of the device, and the power shutdown at the time of non-operation causes problems of odor, bacteria or mold growth due to moisture, There is a risk of electric shock in the operation of high voltage electric arc water, electric dust collector, UV lamp in water.

On the other hand, a regeneration utility model No. 20-0470792 has been filed for an air purifier using a water filter.

The air purifier using the water filter described above is a device for purifying contaminated air by passing air through a water filter formed when a plurality of water pipes of the same standard SUS mesh network vertically erected are dropped.

In the air cleaner using the water filter, the gravity of the water falling vertically is larger than the surface tension, so that there is a difference in thickness of water between the upper mesh network and the water hole connecting portion provided in the plurality of water holes, At the time of overflow, the upper part of the water pipe is not supplied to the lower part of the air pipe and mesh network, so that an air channel without the water filter is formed and the water mesh is not formed or uneven in the lower mesh network. It is expected that the lower water layer becomes thinner than the upper part by dropping, so that air passage efficiency is low. In addition, since this design uses only water, there is a disadvantage that deodorization or removal efficiency of volatile organic compounds (VOCs) is low.

In addition, the air cleaner using the water film filter includes a DC high voltage generator and an underwater pump that connect the negative electrode plate in the water supplied to the cathode mesh net and the anode to the cathode, and thus there is a risk of electric shock.

In addition, although the air purifier using the water filter described above causes the water in the water collecting part to be dispersed in the auxiliary collecting part when the air purifier falls, there is a problem that water in the water supplying part upper water tank, water filter and drain part leaks to the outside of the air purifier I can not say that it has been completely resolved.

In addition, since water is used, there is no antibacterial and antibacterial function during the time other than the operation, and microorganisms grow rapidly, so that clogging of the mesh net and water supply pipe and the inside of the air purifier will become an unpleasant source of pollution.

The air purifier having the humidification function is also disclosed in the patent document 10-0609477.

The air purifier having the humidifying function is configured such that when the water in the upper water tank flows down through a plurality of through holes on the bottom surface of the water tank and flows through the humidifying plate having a wavy mesh shape, Remove dust.

The air purifier having the humidification function uses a technique similar to that of the air purifier using the above-mentioned water filter, and it is expected that the air purifying efficiency will be low due to the above-mentioned reason. Conventional air cleaners for purifying air using water have the disadvantages described above, and in order to overcome them, most of the air cleaners are mostly used in combination of the filter type and the electric collector type.

Patent No. 10-0601029, entitled " Dry and wet compound air purifier with self-cleaning function Registration Practical Utility Model No. 20-0470792, designation; Air purifier using water film filter Patent No. 10-0609477, entitled " Air Purifier with Humidification Function

Accordingly, the present invention relates to a method and apparatus for cleaning air, such as fine dust, ozone, harmful gas, and volatile organic compounds, which are the conventional problems of air cleaners that purify pollutants such as fine dust, ozone, mold, bacteria, harmful gas, It is possible to improve the removal efficiency of organic compounds (VOCs), to suppress microbial growth inside the air washer, to reduce the noise of water droplets when the air passes through the water film, to minimize the occurrence of water leakage and to reduce the water consumption It is intended to reduce the weight and volume of the air washer and further reduce the risk of electric shock by reducing contact between water and electric wires.

The main body 110 of the wet air cleaner 100 according to the present invention is preferably formed in a box shape as shown in FIGS. 1 to 4, but is not limited thereto. For example, it may be formed in the form of a cylinder or a polygonal column

Here, the filter unit 400 includes a plurality of filter stages in which the water film mesh 410 and the scattering prevention net 420 are combined, and the filter stage includes a water film net 410 forming a water film of the washing liquid, Prevention nets 420 that prevent water droplets from scattering due to bubbles blowing through the water film net on the water film net 410.

The water film net 410 is inclined at 80 degrees or less depending on the kind and content of pollutants in the air, the type and content of the washing liquid, and the material of the water film net.

In addition, the filter unit 400 is provided so that a separate washing solution for each filter stage circulates in a water tank, a pump, a water film net, and a water tank.

The water net 410 and the scattering prevention net 420 of the wet air washer 100 of the present invention and the nets 611 and the cover nets 613 of the final filter 610 are made of stainless steel, Fiber, and chemical fiber, and the mesh size is 30 to 2,000 mu m.

The wet air washer minimizes water leakage during body conduction.

 Further, as the pump for pumping the washing solution of the water tank to the mesh of each filter stage, it is preferable that the non-contact pump and the reciprocating pump 540 are used instead of the underwater pump.

Hereinafter, the wet air washer according to the present invention will be described in detail.

First, as shown in FIGS. 1 to 4, the plate for forming the outside of the main body of the wet type air cleaner according to the present invention is used for replacing or replacing the cleaning liquid during use of the wet type air cleaner, It can be opened and closed for troubleshooting. The filter panel 120 is used for cleaning and managing the filter unit and the instrument panel 130. The discharge panel 140 is used for cleaning the final filter and the final filter receiver groove 620, Cleaning and management of the inside of the filter unit and the pump, cleaning and management of the filter unit in the water supply floating plate 150, and replenishing and replacement of the water tank and auxiliary water tank in the water tank and the auxiliary water tank, .

The wet air washer according to the present invention is divided into a suction unit 200, a blower unit 300, a filter unit 400, a water supply unit 500, and a discharge unit 600 according to functions, 10 to FIG. 10 will be described in detail as follows.

First, the suction unit 200 of the wet air cleaner functions as a pre-filtering function of the contaminated air in the pre-filter, and the suction port 210 Relatively dust particles such as fiber dust, workplace dust, hair, etc. of contaminated air are attached to the pre-filter 220 and are subjected to reduced pressure filtration.

The prefilter has a coarse mesh structure and is mainly attached to the net due to the size of the mesh and the size of the polluted particles. As the number of adhered pollution particles increases, the polluted air is less likely to pass therethrough. It is important to periodically clean the mesh as it does not block the mesh of the scattering net. Since the contaminated air is sucked and passed, the suction port and the pre-filter are required to have a structure and material that are easy to be detached and easy to remove pollutants and clean the water.

The blowing unit 300 functions to provide the energy that allows the contaminated air to pass through the filter membrane, and extends from the pre-filter to the water film net. The blowing fan 310, which is provided inside the body, Air is sucked into the prefilter under reduced pressure, and forced air is blown into the net of the water film to give energy to push it with pressure.

The water shutoff plate 320 collects the washing liquid that can be dripped from the water net and sends it to the water discharge outlet 340. The water leakage net 340 prevents the contaminated air passing through the air blowing fan from passing through the net, It is attached in a sealed manner so as not to happen.

In addition, the above-mentioned water shutoff plate maintains a smooth flow of dripping water and a proper inclination so as to be blown in the vertical direction as much as possible from the lower part of the water film net. The fan motor is protected by the fan motor protecting plate 330 because the washing liquid may be dripped in the blowing part.

The filter unit 400 functions to purify the air sucked in the adhesion, adsorption, and dissolution of contaminants in a water film net, and has at least one filter stage composed of one water film net and a scattering prevention net, The washing liquid of the water tank 510 is pumped to the water net with the water netting 412 and the water netting lower netting 411 located parallel to each other within a distance such that the water netting can be formed by the surface tension of the washing liquid, The washing liquid flows through the washing liquid passing-through slit 415 into the passage of the washing liquid formed by the upper water net 412 and the reinforcing plate of the lower water net, thereby forming a water bath of the washing liquid, When the contaminated air that has been pressurized after passing through the blowing fan 310 passes through the water film of the washing liquid formed with the minute net of the water film net from the lower part of the water film net to the upper part, the water is made into fine bubbles on the upper surface of the water film, The air pollutants are adhered, adsorbed and dissolved in the fine bubbles of the washing liquid, which is an aqueous solution in which water, water and organic acid are dissolved, and the water droplets formed when the bubbles burst, To purify the contaminated air.

Although the filter unit 400 is preferably composed of a plurality of filter stages as exemplified by the four stages of the filter stage 480 in the embodiment, The filter unit may be constituted by one filter stage.

The filter stage is composed of a water film net forming a water film of the washing liquid and a scattering net preventing water droplets from scattering due to bubbles blowing through the water film net on the water film net.

However, the water film formed by the upper water net 412 and the lower water net 411 is uniform and can be adhered with a strong surface tension, resulting in less scattered water droplets. And it is possible to minimize leakage when the main body is turned off, which is advantageous of the double layer net.

In addition, since the washing liquid in the filter stage is circulated by the scattering net as the washing liquid flows through the net, and the droplets of the scattered washing liquid become larger and fall back into the net, And a separate washing solution is circulated to the water tank, the pump net, the water film net, and the water tank for each filter stage.

The filter stage composed of the water film net and the scattering prevention net is provided in the space inside the filter substrate 120 and the water discharge floating plate 150 so as to keep a plurality of filter stages at a predetermined distance from the bottom, .

The water film net 410 is formed by joining a plate-shaped water film upper net 412 and a water film lower net 411 to each other and has water supply grooves 413 and drain grooves 416 at both ends of the plate-shaped net.

More specifically, the water film net 410 described above has a mesh net 440 at the edge of a plate-shaped net to prevent warping of the net and form a water film having a constant thickness, And a reinforcement frame 450 for forming a washing liquid passing slit 415 for allowing the water to pass along the upper water net 412 and the lower water net 412. The upper water net 412 has the same shape as the upper water net, And is connected to the lower mesh 411 in the form of water.

A water supply hole 414 and a drain hole 417 are formed in the water supply groove 413 and the water discharge groove 416 to connect the water supply pipe 531 and the water discharge pipe 532.

The splash proof net 420 is positioned above the water curtain wall 410 and has an edge of a plate shaped net to maintain the shape of the splash proof net and to push the splash proof net into the net guide 470, And a netting 440 is provided.

The anti-scattering net 420 may include a reinforcing frame 450 having a function of preventing the web from flowing down along the slope of the anti-scattering net as the water drops of the washing liquid adhered to the anti- .

That is, when the contaminated air continues to make fine bubbles of the washing liquid from the surface of the water film net, the water droplets scattered and scattered on the scattering prevention net attaches to the water droplets of the washing liquid gradually increasing, Or if there is an inclination of the anti-scattering net, it flows along the inclined surface of the anti-scattering net and forms a thin water film and falls into the net of the water film.

In the case of the anti-scattering net that performs this function, a sufficient distance from the net should be ensured so that the water film on the net of water film and the water droplet adhered to the anti-scattering net can not form a water film again due to the surface tension of the washing liquid.

The desired distance between the shatterproof net and the mesh net is preferably about 1.5 to 3 cm. However, the desired level of the size and weight of the main body, the required volume of the main body, the inclination of the filter end, the type and concentration of the washing liquid, It depends on the size of the mesh, the diameter of the mesh.

In the meantime, it is preferable that the anti-scattering net of the wet type air cleaner according to the present invention is composed of a single layer on one filter end as in the above embodiment, but it is preferable to use a washing liquid, It is also possible to provide two layers of scattering prevention net on one filter stage.

In addition, the anti-scattering net 420 is formed of a reinforcing net, which has a mesh net 440 at the edge of a net having a plate shape to prevent warping of the net and form a scattering liquid passage of the net, , The cleaning liquid partially forms a water film on the shatterproof net, and thus has a function of purifying contaminated air such as a water film net.

In addition, the above-mentioned scattering-proof net minimizes the scattering of the washing solution into the filter part due to scattering of the washing solution in the water film net and the loss of the washing solution due to evaporation.

The water film net has a net handle 460 on the side of a water supply groove where a water supply hole is located and a mesh handle 460 is provided on a side of a mesh side in the direction of the water supply pipe. The mesh knob is provided so that the mesh net and the anti-scattering net are in close contact with the mesh tapes 470 and the netting packing 471 so that they can be pushed in and out easily.

The water film net and the anti-scattering net are placed in parallel with each other, and the water film net and the anti-scattering net are placed in parallel with each other, and the body The end of the water supply groove 413 is inclined downwardly by 80 degrees with respect to the inner bottom surface of the water supply groove 110, but preferably it is inclined by 3 to 17 degrees.

The slope increases the recovery rate of the contaminants and the water film by the flow of the water film due to the inclination after the air passage, and increases the water film area and the water film penetration defense of the falling water drops.

Here, the above-mentioned water film mesh, scattering prevention mesh and net of the final filter are made of stainless steel, alloy, nylon or chemical fiber, and mesh size is 30 to 2,000 mu m.

The discharge unit 600 has a function of adsorbing humidification and dehumidification of the purified air of the cleaned air and discharging air from the dust-preventing net to the discharge port 650, A final filter 610 in which the purified air in the filter unit 400 is finally adjusted to an appropriate moisture content, a final filter support groove 620 for supporting the final filter, A final filter seal 630 to seal the clearance between the final filter and the final filter support groove 620 to allow the final filter seal 630 to pass therethrough, a packing compression bracket 640 to compress and secure the final filter seal 630, And a discharge port 650 for discharge.

2 to 4 and 7, the conical final filter 610 is composed of a supporting net 611, a filter medium 612, and a covering net 613.

The final filter is preferably formed in a conical shape as shown, but is not limited thereto.

The support net 611 and the cover net 613 are made of a net so that purified air can pass easily and serve as a support and cover for the filter medium 612 of the final filter to uniformly spread the filter medium, Helping to pass the final filter at the most uniform pressure and helping to maintain the shape of the final filter.

Here, the above-mentioned final filter medium imparts a final filtration function for humidifying or dehumidifying the purified air in the net, while at the same time removing residual washing liquid particles. When the final filter receiving groove 620 is filled with water and the final filter is wetted with water, the water in the final filter receiving groove 620 is mixed with the receiving net 611 of the final filter, the covering net 613, The filter medium is wetted by the capillary phenomenon and humidifies the purified air passing through the final filter by raising the humidity. The dehumidification of the final filter does not fill the final filter support groove 620 with water but is filtered between the support net 611 of the final filter and the cover net 613 using a filter material made of a thick, Dehumidification is achieved by lowering the humidity of the passing purified air.

The final filter provides a final filtration function for adsorbing and removing the residual washing liquid particles of the purified air at the same time while humidifying or dehumidifying the purified air. The final filter medium includes natural fibers such as cotton, silk, Synthetic fibers such as nylon, polyester, spandex, porous plastic, glass fiber, non-woven fabric and the like are used, and the final filter is selected from among various final filters of materials and thicknesses that can easily pass the purified air. Especially, glass fiber is effective for noise reduction with excellent sound absorbing material against sound waves.

Hereinafter, the principle of air cleaning of the wet type air cleaner according to the present invention will be described in more detail with reference to the accompanying drawings with reference to FIGS. 1 to 10, with reference to Examples and Experimental Examples.

The main principle of the air cleaning of the wet type air cleaner according to the present invention is that the air contaminated by the blowing fan 310 is sucked into the main body to adhere and remove relatively large contaminant particles to the prefilter 220, Which is an aqueous solution of water, a salt, a base, and an organic acid when the pressurized and contaminated air passes through the water film of the washing liquid formed between the upper water net 412 of the water net and the lower water net of the water net When fine air bubbles are generated, air pollutants are adhered to the fine bubbles of the cleaning liquid and the water droplets generated when the air bubbles are blown, and they are removed by adsorption and dissolution to purify the contaminated air.

As the mesh thickness of the water film upper net 412 and the water film lower mesh is finer and the thickness of the water film is finer, a fine washing liquid bubbles are formed, and the water net existing as many as the filter stages and the vibration due to the splash- As the energy vibrates the filter part, the wet air cleaner of the present invention improves the pollutant removal efficiency in the air, and the noise generated when the air bubbles burst due to the microbubble disruption is reduced.

The purified air passes through the final filter 610, and finally the washing liquid component is adsorbed, and is dehumidified or humidified and adjusted to an appropriate moisture content.

According to general theory, when air bubbles float on the surface of a liquid, the liquid flows downward, and the thickness of the thin liquid film surrounding the air bubbles becomes thin. When the film thickness is less than 10 nm, the bubbles lose their properties The bubble is thereby destroyed. '

Further, the larger the surface area of the contaminated air contacting with the cleaning liquid, the smaller the size of the air bubbles, and the more the air bubbles touch the water surface, the higher the pollutant removal efficiency will be.

In addition, the PM 0.1 and harmful gas are difficult to be filtered by a fine mesh filter, and the removal of harmful gas by activated carbon is low in efficiency due to the adsorption of gas on the solid surface, Is absorbed by chemical substances that change into neutral or harmless substances by chemical reaction.

The principle of air purification of the wet type air cleaner according to the present invention will be described below for each filter.

First, the prefilter 220 of the wet type air cleaner according to the present invention has a spruced net structure, and relatively large contaminant particles are adhered to and removed from the net due to the size of the mesh and the size difference of the contaminant particles.

The water film net is placed in parallel with the water film upper net 412 and the lower water net 411 in a distance that the water film can be formed by the surface tension of the washing liquid, The washing liquid flows through the washing liquid passing slit 415 into the passage of the washing liquid formed by the upper water net 412 and the reinforcing plate of the lower water net, thereby forming a water bath of the washing liquid, When the contaminated air that has been pressurized after passing through the blowing fan 310 passes through the water film of the washing liquid formed and the fine mesh of the water film net from the bottom of the water film net to the top, minute bubbles are formed on the surface of the water film, , And organic acid dissolved in water, and then attaching the contaminants of the polluted air to the water droplets formed when the air bubbles and the fine bubbles of the washing liquid are blown out, Adsorption, and dissolution, thereby purifying contaminated air.

In particular, when the contaminants are ozone, sulfur dioxide, fungi, bacteria, volatile organic compounds (VOCs) and inorganic substances, the washing liquid will have higher efficiency of removing salts, bases and organic acids than water.

For example, ozone, which is a serious air pollutant, decomposes ozone and becomes harmless to human body when aqueous solution of potassium iodide (KI) is used as a washing solution.

O 3 + 2KI + H 2 O → O 2 + I 2 + 2KOH

This reaction is the reaction used to quantify ozone, and potassium iodide is a food additive added to supplement the insufficient iodine nutrients in the human body.

Especially, the countermeasures against ozone, which is called 'the assassin of silence', have almost no coping methods other than to prevent automobile operation which is one of the causes of outdoor activities and ozone generation.

It is also known that sulfur dioxide, which is mainly contained in soot in automobiles, factories, and thermal power plants, is washed with calcium hydroxide and aqueous sodium hydroxide to remove more than 90% of sulfur dioxide.

In the case of yellow dust containing pollutants such as nitrogen, sulfur oxides and heavy metals emitted from cities and industrial complexes, it will be washed well in acid or alkali solution rather than water.

The organic acid has a high affinity with an organic compound, so that the efficiency of removing organic contaminants will be high.

As described above, it is possible to prepare various kinds of cleaning liquids with effective ingredients and contents for each pollutant, and to use the same for each water tank in the wet air cleaner of the present invention, various kinds of contaminants can be removed at one time. , The water film net existing as many as the number of filter stages and the anti-scattering net are passed repeatedly, and the efficiency of removing contaminants is greatly increased.

In addition, as the contaminated air is blown into fine bubbles from the water film net, the removal efficiency of the pollutant increases.

The anti-scattering net, which performs the auxiliary filter function of the wet air cleaning according to the present invention, has a shape similar to that of the upper water net and the washing liquid partially forms a water film on the anti-scattering net, It also has some purification functions.

In addition, the anti-scattering net is minimized by the scattering of the washing solution in the filter part due to the scattering of the washing solution in the water film net and the evaporation of the washing solution by evaporation of the washing solution, prevent.

The final filter includes a final filtration function that removes residual washing liquid particles at the same time while humidifying or dehumidifying the purified air in the mesh net depending on the material of the final filter filter material 612 and the water used in the final filter receiving groove 620 do.

When the final filter receiving groove 620 is filled with water and the final filter is brought into contact with water, the water in the final filter receiving groove 620 flows into the receiving net 611 of the final filter, the covering net 613, And the filter medium are wetted by the capillary phenomenon and humidified by increasing the humidity to the purified air passing through the final filter.

The dehumidification of the final filter does not fill the final filter support grooves 620 but passes through the final filter using a filter material made of dry or thick fibers or fibers between the nets 611 of the final filter and the cover nets 613 Dehumidification is achieved by lowering the humidity of purified air.

Thus, in the present invention, instead of spraying the cleaning liquid into the air, the cleaning liquid is passed through the water film of the water film net, and the contaminated air is made to contact therewith, and the scattered cleaning liquid is attached by the scattering- Thereby preventing the leakage of air to the outside of the wet air cleaner, thereby improving the cleaning efficiency and improving the problem of wetting the purified air.

Hereinafter, the present invention will be described in more detail with reference to the following examples and experimental examples. However, the following examples and experimental examples are intended to illustrate the contents of the present invention, but the scope of the invention is not limited by the examples and the experimental examples.

The washing liquid, the water film and the net which are the core of the wet air washer according to the present invention are described as examples.

Water film formation using washing liquid and net

A water film was formed on the net carefully with 1 ml of tap water, 10% salt water and 10% citric acid aqueous solution which can be used as a washing solution and having a diameter of 2 cm (water film thickness: about 0.3 cm) The average value measured three times is shown in Table 1 below.

As shown in Table 1, a water film having a mesh size of 26 to 1200 μm and a thickness of about 0.3 cm could be formed on a single net made of nylon, stainless steel (SS), and chemical fiber with a washing solution of water, brine, and citric acid solution . In addition, a thin water film remained in the net which fell off by water droplet of about 0.3cm thickness which was on the net. It is possible to form a water film even with a mesh of a single layer so that it is possible to form a water film as well as a double layer water film net 410 of the wet air cleaner according to the present invention and a single layer scattering prevention net 420.

In the mesh size, the smaller the mesh size, the longer the formation and maintenance of the water film can be maintained. The net material was made of nylon, stainless steel (SS), and chemical fiber, and it showed that it is possible to maintain formation of water film.

The washing solution continued to form a water film in the order of 10% brine, tap water, and 10% citric acid solution. This is because the water film formation has surface tension [water (25 캜); 72 dyne / cm, 35% brine (20 캜); 82.6 dyne / cm]. Unusually, 1200 μm nylon mesh has long lasted water film formation in 10% citric acid wash.

The 26 ㎛ net, unusually, the 10% citric acid washing solution was wetted by the water film to the diameter of 6 cm, and the wetting of the net occurred, but the water droplet did not fall down the net, and the tap water and the 10% brine did not wet the net, It lasted for a long time.

≪ Experimental Example 1 >

The net used in Examples and Experimental Examples of the present invention are shown in Table 2 by examining mesh size, wire diameter and netting material with a magnifying glass and vernier caliper. Particularly, in [Example 1], the occurrence of net wetting of the 26% mesh 10% citric acid washing liquid is thought to be caused by the mesh of the net with a thin plate-like wire.

The standard body (20 cm in diameter, 7.5 cm in diameter) was made of STANDARD SIEVE (Seoul).

The mesh wire of the 250 ㎛ chemical fiber net is about twelve small strands twisted, and a small lint can be seen in the mesh, so that the mesh can be made compact.

Mesh penetration height of slope and water droplets

In order to determine the proper separation distances between the upper water net 412 and the lower net 411, the water net and the anti-scatter net, and the filter end used in the present invention, a single net having a horizontal or 12 ° inclination maintained, The pipette was filled with tap water, fixed on a stand, and water droplets (0.06 ml / drop) were freely dropped to determine the height of the mesh through the water droplets.

As shown in [Table 3], the smaller the mesh size, the higher the net through-hole height, and the net diameter of the net influenced the mesh net height in the sloping net.

The 26 탆 mesh could not measure the height of the water droplet.

When the net is in a horizontal plane, when water drops on the net, water droplets are attached to the net by a surface tension to about 1 cm below the net through the net, but if it is pushed about 1 cm away, do.

When the net is an inclined surface, when the water drops fall on the net top part, the part flows down along the net top surface, only a part of the water passes through the net, and the inclined surface has the effect of reducing the mesh size, The height of the net through the net increases.

When the net's surface was wet with water, the meniscus of the net around the water was not dry and formed a thin water film.

Water passage pressure

In order to examine the pressure passing through the water film of the wet air washing machine water net of the present invention from the lower part to the upper part, a standard body having a thickness of 0.6 cm was formed while generating air bubbles in water with a bubble generator (air generation of 34 ml / sec) And the pressure at which the bubbles first pass through the water film of the standard net is measured and shown in Table 4.

In the experiment, a transparent cellophane was wound in a 23 cm cylinder and connected with a waterproof tape.

The smaller the mesh size, the larger the initial bubble passing pressure, and the 26 ㎛ net was 18 cmH 2 O or more, making it difficult for air to pass through the water film (1 atmospheric pressure: 1033 H 2 O)

Also, the smaller the mesh size, the more air is left in the sieve when the air bubble escapes.

In addition, the thicker the water film on the net, the more the air bubbles gathered, and the larger the air bubbles, the smaller the air bubbles are, the smaller the air bubbles are.

Passage of washing liquid in water net

In order to examine the passage pressure of the washing liquid used in the present invention, a water film was formed with a separation distance of 0.3 cm between the two-ply net maintained at a horizontal or 12 ° inclination, and then a tap water was filled in a 50 ml pipette, , The water drop (0.06 ml / drop) was freely dropped and the height of the passage of the water droplet was measured and shown in Table 5. The washing solution used was tap water, 10% brine, and 10% citric acid solution. The upper net and the lower net of the two-ply net are 150 μm net and 135 μm net, respectively. As shown in [Table 5], the washing solution had a high passage height in the order of 10% brine, tap water, and 10% citric acid solution, and the inclined nets were higher than the horizontal nets. Particularly, the tap water of Example 2 was 10.5 cm / horizontal, 13.7 cm / inclination with a simple net height of 135 m single-ply net and 150 m single-ply net and 11 cm / horizontal and 18 cm / / The slope result is thought to be due to the effect of refinement of the mesh due to overlapping of the upper mesh and the lower mesh and the thickness of the water film of 0.3 cm.

The function of anti-scatter net

In order to confirm the separation distance and the water droplet scattering between the water film net and the non-scattering net of the wet air washer according to the present invention, at a position of 0.6 cm above the 600 .mu.m standard net corresponding to the lower water film, The fiber net was fixed to form a 0.6 cm water film. A 135 m net corresponding to the anti-scattering net was fixed at a distance of 2 cm above the upper water net of the water film, and a 12 degree inclination was maintained. And the air bubbles generated from the water layer of 0.6 cm were blown out, and water droplets rose to the upper part of the 135 탆 net surface of the scattering prevention net, and then the water droplets penetrated to the lower side of the 135 탆 net.

At this time, water droplets scattered over the 135 mu m net, which is a scattering-preventive net, were not observed, and the function of the anti-scattering net was exhibited.

Water film stability of water film net

In order to examine the water film stability of the wet air washing machine water net of the present invention, a 420-μm standard and a 250-μm standard were separated by a watertight tape to form a 2-cm thick water film, We examined three kinds of water film stability.

First, a transparent cellophane sheet wound in a cylindrical shape with a diameter of 23 cm and connected with a waterproof tape was placed on a 250 m standard wheel serving as a lower netting of water, and a bubble was generated in water with a bubble generator (air generation of 34 ml / sec) The bubble was continuously bubbled at a pressure of 7.5 cm H 2 O, the bubble generator was turned off, and the bubble was lifted at a pressure of 1.5 cm H 2 O, The formation breaks down and flows down. This indicates that the 2 cm thick membrane is stable up to a buffer pressure of 6 cm H 2 O.

Second, a 2 cm thick film formed by lifting a connected standard with a formed 2 cm water film into the air indicates that it is not disassembled and is stable.

Third, when a connected standard with a 2 cm water layer formed is maintained at an angle of 12 °, a drop of water drops at the top of the water net, and a drop of water drops at the bottom of the water net almost simultaneously. This indicates that when the water drops of the washing solution 1 are supplied to the water grooves of the water film net, the water drops of the washing solution 1 are drained into the drain grooves of the water film net.

Multiple net effect

In order to investigate the effect of the multiple filter stages of the wet air cleaner of the present invention, a standard body having two water films formed thereon was fabricated into a standard body in which a 0.6 cm water film was formed while generating bubbles in water with a bubble generator (air generation of 136 ml / Was flooded while keeping it horizontal, and bubbles were observed to be generated.

In the above standard, a water net at the bottom was fixed at a distance of 0.6 cm above a net of 1000 μm standard net, which is a lower net of a water channel, and a 250 μm thick chemical net was fixed to an upper net of a water channel to form a 0.6 cm water channel. The water net at the top was fixed at a distance of 0.6 cm above the net of 1000 μm standard net, which is the lower net of the water channel, and 250 μm of the chemical net of net was fixed to the upper net of the water channel, and the transparent cello paper was wound with a waterproof tape.

The result of observing bubble generation was that the shock wave was transmitted to the water net at the top when the bubble passed through the net at the bottom of the water film, and the bubble burst at the same time in 1.5 seconds after the bubble was passed through the whole net of the standard body, (17 times bubble burst / minute)

In the comparative test, bubbling of a 1000 mesh sieve with one water mesh, that is, a water mesh, was formed by air bubbles in a portion of the mesh of the standard and passed through a large air mass.
