Description

Wet air purifier

The present invention is a wet air purifier, which will be described in more detail. The purified water is introduced into the purified water flow path of the helical double filter having pores, and the contaminated air is sucked into the air induction of the spiral double filter to efficiently remove the purified air while the air passes. It is to be purified.

As the technology developed through the age of industrialization, nature was continuously polluted, and in particular, air pollution reached a serious level.

In recent years, as the problems of fine dust and ultrafine dust are raised, the interest and use of air purifiers for purifying fine dust and ultrafine dust are increasing.

It keeps indoor air clean at residences, schools, offices, and industrial sites, creating a pleasant environment for people and animals as well as living, making life more comfortable, and preventing respiratory diseases caused by fine dust. In modern society, where air pollution is getting worse, air purifier has become an essential element in life.

Various methods of purifying the air have been developed, but in the case of dry air purifiers, the filter has to be replaced regularly, which causes inconveniences in terms of maintenance and management and costs.

In the case of the wet air purifier, the purification efficiency is low, because it is more difficult to purify than the dry type, and the purification efficiency is low. Since the air passing through the purifier contains moisture, the humidity in the air is high, creating an uncomfortable environment. .

Among the techniques to solve this problem, as disclosed in the Republic of Korea Utility Model No. 2009 No. 0008266 (published on August 18, 2009), the air inlet is formed on both sides and the air casing is formed on the upper side, and the air inlet An adsorption plate, each of which is installed to purify the inflow air and has a plurality of inclined holes, a fiber filling plate which is installed at each air inlet and removes contaminants contained in the air that has passed through the adsorption plate, and is installed inside the main body casing A watering pipe part for injecting water into the fiber filling plate, a circulation fan installed on the upper side of the main body casing to discharge air introduced through the air inlet to the air outlet port, and a wall surrounding the main body casing to form a reservoir part. Provided is a wet air purifying apparatus comprising a.

However, the above technique is required to periodically replace the contaminants as the contaminants adhere to the adsorption plate that removes the pollutants, deodorizes and antibacterial, and the fiber filling plate that filters the contaminants that pass through without being filtered out of the adsorption plate. In the internal space of the air, since the air rises directly from the side to the top, it is difficult to purify all the air by the general injection nozzle, and the time to be purified is also very short.

As disclosed in Korean Patent Laid-Open Publication No. 20120020542 (published on March 08, 2012) of the prior art, instead of spraying general water with a spray method, water introduced from the outside is wound with a string wound on the water frame. When passing through the filter, the contaminants mixed in the air are purified by the adhesion of water, and the water passing through the water filter is prevented from scattering to the outside by using a water filter installed inclined backwards.

However, the technique is intended to purify the air through a water filter formed in a plurality of strings wound vertically, the air that does not pass through the water filter by the air port is discharged directly through the air movement passage without filtering, There is a problem in that the structure is low purification because there is an unpurified air between the string formed in the filter and the string, and excessively increase the humidity in the room by intentionally increasing the amount of vaporization of water.

The suction pipe 21 may form the suction hopper 23 of the upper and lower narrowings in the suction pipe 21 so that the diameter of the outlet is smaller than the diameter of the inlet. When the diameter of the suction pipe 21 through which the fluid is reduced becomes small, the flow rate is increased. Since it is faster, it is possible to transfer the air to the purification section 4 more quickly and strongly.

The end of the suction pipe 21 is in communication with the center of the purification unit (4).

In the purification section 4, a double filter 41, which is a pair of vertical plates spaced apart slightly to have a purification water flow path 42 therein, is formed to be bent in a spiral shape, and the purification water flow path 42 has a spiral shape. On the opposite side, an air induction path 43 is formed between the double filter 41 and the double filter 41.

A plurality of fine injection holes 44 are formed in the side surface of the double filter 41 so that the purified water flow path 42 and the air flow path 43 communicate with each other to allow the purified water to be injected or flowed.

As shown in FIGS. 2A and 3A, the double filter 41 may be formed such that a double filter surface is formed in a spiral shape, or as shown in FIGS. 2B and 3B, a double filter surface may have a substantially rectangular shape. It may be formed to form a spiral.

Outside polluted air introduced into the center of the air induction path 43 formed in the spiral double filter 41 is rotated through the spiral air induction path 43 to turn to the outer side of the spiral.

The supply part 3 and the purification part 4 are partitioned off by the upper partition 12.

The upper end of the double filter 41 of the purification unit 4 is connected to the supply hole 31 formed in the upper partition 12 to be coupled to the purified water flow path 42 or the upper end of the double filter 41 is supplied to the supply hole 31. It may be communicated so as to protrude higher than the position of 31.

Purified water supplied from the supply unit 3 and filled in the purified water flow path 42 is injected or flowed down through the injection holes 44 formed on the side of the double filter 41.

As shown in FIGS. 2A and 2B, the air helically rotating through the air inflow path 43 flows rapidly by the suction fan 22, and the air fluid to flow in a straight direction stands vertically with the curved double filter 41. It is forced to rotate in a spiral contact with the wall.

The air rotating in a spiral flows as close as possible to the side of the double filter 41 due to the centrifugal force, thereby increasing the degree of contact with the purified water.

Therefore, the purified water injected through the injection hole 44 of the double filter 41 to the air rotating in a spiral is directly injected or purified, or the double filter 41 wetted by the purified water flowing through the injection hole 44 As the air rotating spirally on the wall of the) is transported closely, the dust contained in the air meets the moisture to sink the heavy dust and so on to purify the air. It is to work.

In the purification section 4, the air is purified by the purified water while rotating from the center to the outer surface along the spiral shape of the double filter 41, and is discharged between the end of the double filter 41 and the inner surface of the case 1. The guide piece 45 is placed to prevent air outside the helical air induction path 43 of the double filter 41 from being infinitely rotated on the outermost side of the double filter 41 and at the same time openings on one side of the case 1. Induces the air to be discharged through the discharge portion 6 is formed so that.

The discharge part 6 includes a dehumidification means 62 for preventing the intake of foreign substances from the outside and lowering the humidity of the discharged air, and before and after the dehumidifying means 62 to fix the dehumidifying means 62. 61) can be formed.

The dehumidifying means 62 may be replaced regularly by using a ventilation bag containing deliquescent substances such as calcium chloride, magnesium chloride, lithium chloride, lithium bromide, silica gel, and the like.

Purified water injected or flowed down through the injection hole 44 of the double filter 41 is accumulated in the recovery part 5 which is the lower part of the case 1, and the purification part collected and used in the recovery part 5 is supplied to the supply part 3. Pump 51 and the resupply pipe 52 for raising the furnace is formed.

The resupply pipe 52 is connected to the pump 51 and extends to communicate with the supply unit 3, and the operation of the pump 51 may be operated at regular intervals as set in advance, or to the supply unit 3. When the water level of the supply unit 3 is lowered through the formed water level sensor 32, the pump 51 operates. When the water level of the supply unit 3 is higher than the water level sensor 32, the pump 51 stops the operation. It may be.

Therefore, when the pump 51 of the recovery unit 5 is driven to supply the used purified water of the recovery unit 5 to the resupply pipe 52, directly from the resupply pipe 52 without a space for storing a separate purified water. Purified water is supplied to the purified water flow path 42.

When the cap 7 is configured as described above, since the pressure of the pump 51 is transmitted to the purified water flow path 42 of the supply part 3 as it is, the purified water can be supplied at a desired pressure, and the purified water is injected from the injection hole 44. It prevents the flow down and can be ejected with a high blowing force.

Since the supply unit 3 is in a closed state by the cap 7, the purified water is supplied by supplying purified water in the absence of purified water when the wet air purifier 100 is initially driven, or by purifying water evaporating through the discharge unit 6. In case of addition to the supply part 3, the inlet pipe 14 and a valve may be additionally installed at one side of the supply part 3.

In addition to the above configuration, a drain pipe 15 and a valve may be further installed on one side of the recovery unit 5 to discharge the purified water used for purified water to the outside.
