Description

[0001] Wet dust collector with improved dust collecting efficiency [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet type dust collecting apparatus, and more particularly, to a wet type dust collecting apparatus capable of collecting dust contained in air to produce clean air.

Generally, a dust collecting device is a device for purifying air containing various contaminants such as fine dust and discharging clean air. It is a device for purifying air, and for removing odors and fine particles such as mites, pollen, pet hair To provide a pleasant and healthy environment.

These dust collectors are divided into two types, dry type and wet type. The dry type dust collecting device can be classified into an electric dust collection type and a filter filtration type.

The wet type dust collecting apparatus purifies polluted matter such as dust or gas by contacting the inhaled air with water or the like to purify the polluted matter such as dust or gas and does not need to replace the filter and has a small noise. The use thereof is increasing.

However, most of the wet dust collectors proposed so far have a problem in that the water is simply dropped from the top to the bottom, and the dust is adsorbed on the falling water, so that the cleaning ability of dust in the air is not as high as expected.

Application No. 10-2010-0075984 (registration number: 10-1256512, entitled " Wet dust collector with improved purification performance)

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wet type dust collector having improved dust collecting efficiency by collecting dust contained in air in water several times in succession using water.

According to an aspect of the present invention, there is provided a wet type dust collecting apparatus including: a water tank in which water is stored; A cyclone provided on an upper surface of the water tank and having an intake port for introducing dust-containing air into the lower side and an exhaust port for discharging the introduced air; A plurality of water injection nozzles disposed radially up and down on the inserted portion of the cyclone through the upper surface of the cyclone and spraying the water stored in the water tank into the cyclone by the pressure of the pump A water injection pipe; An air induction member installed on the upper surface of the water tank is filled with water stored in the water tank and connected to the discharge port of the cyclone and the air introduced through the discharge port flows above the water surface A housing; And a suction fan for sucking air inside the housing through a discharge pipe connected to the housing.

In addition, a flow path plate is installed in the housing to guide the air introduced into the housing through the outlet of the cyclone toward the air induction member.

The water stored in the water tank flows over the upper end portion of the flow path forming plate and flows along the wall surface of the flow path forming plate Down.

Here, the water stored in the water tank is supplied by pumping water stored in the water tank.

In addition, the outlet is sloped downwardly in the housing.

In addition, a demister filter is installed in the housing, and the air having passed through the air induction member is discharged to the discharge pipe through the demister filter.

According to the wet dust collecting apparatus of the present invention having the dust collecting efficiency as described above, the dust in the air is collected by the water sprayed through the water spray nozzle, and once again the dust is collected by the water flowing down the wall surface of the flow path plate. And has a structure in which dust is collected again by the water contained in the housing, so that the dust collecting efficiency is very high.

In addition, there is an advantage that the dust collecting efficiency can be further improved by allowing the air induction member installed above and below the water surface to repeatedly flow the air out of the water and the water.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front view of a wet type dust collector with improved dust collecting efficiency according to the present invention. FIG.
2 is a top view of a wet type dust collector with improved dust collecting efficiency according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a wet type dust collector with improved dust collecting efficiency according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a wet type dust collecting apparatus with improved dust collecting efficiency according to the present invention, and FIG. 2 is a top view of a wet type dust collecting apparatus with improved dust collecting efficiency according to the present invention.

The wet dust collector with improved dust collection efficiency according to the present invention includes a water tank 10, a cyclone 20 installed on one side of the upper surface of the water tank 10, water from the cyclone 20 And a suction fan 50 for sucking air inside the housing 40. The water injection pipe 30 guides the inside of the housing 40 to the inside of the housing 40, .

The water tank 10 has a smaller width as it goes downward, stores water in the inner space, and has a drain 11 for discharging water at the lower end thereof.

The cyclone 20 is installed on the upper surface of the water tank 10 so as to communicate with the water tank 10 and has a cylindrical shape at the upper part and a conical shape with a lower pointed shape, The lower end thereof is opened and connected to the inner space of the water tank 10. The cyclone 20 is provided with a suction port 21 and a discharge port 22.

The suction port (21) is provided on the lower side wall of the cyclone (20), and air including dust is introduced.

The discharge port 22 is provided on the upper wall of the cyclone 20, and the air introduced into the cyclone 20 is discharged.

The air that has flowed into the cyclone 20 through the inlet 21 rises in the shape of a whirl through the inner wall surface of the cyclone 20 and then is discharged to the outside of the cyclone 20 through the outlet 22.

One end of the water injection pipe 30 is connected to the water tank 10 and the other end thereof is connected to the cyclone 20. A pump 31 is installed on the pipe and the water tank 10 Is introduced into the water injection pipe 30 and then guided to the cyclone 20. [

The upper end portion of the water injection pipe 30 is inserted into the cyclone 20 through the upper surface of the cyclone 20. A plurality of water spray nozzles 32 arranged in the vertical direction are installed radially in the portion inserted into the cyclone 20. [ The water in the water tank 10 flowing into the water injection pipe 30 is injected into the cyclone 20 through the water injection nozzle 32 by the pressure of the pump 31. [

As the water is sprayed into the cyclone 20, water is sprayed into the air flowing upward while rotating in the cyclone 20 in the form of a whirl, so that the dust contained in the air is adsorbed in the sprayed water. The water adsorbed by the dust drops into the water tank 10 through the lower side of the opened cyclone 20. [

The housing 40 is installed on the upper surface of the water tank 10 so that the water stored in the water tank 10 is filled in the lower side at a certain height and the upper side is connected to the discharge port 22 of the cyclone 20.

In the housing 40, a flow path forming plate 41, an air induction member 42, a water tank 43, and a demister filter 44 are installed.

The flow path forming plate 41 guides the air introduced into the housing 40 through the discharge port 22 of the cyclone 20 to the air induction member 42. The flow path forming plate 41 is installed in the housing 40 so as to be long in the vertical direction at a position spaced from the one side of the housing 40 in which the discharge port 22 is installed.

The channel forming plate 41 is slightly distanced from the upper surface of the housing 40 at the upper end and is submerged in the water filled in the lower portion of the housing 40. The air flowing into the housing 40 through the discharge port 22 of the cyclone 20 flows downward against the flow path plate 41 and collides with the water filled in the lower portion of the housing 40.

On the other hand, the discharge port 22 of the cyclone 20 is installed on the housing 40 so as to be inclined downward when it is connected to the housing 40. Therefore, air can be smoothly introduced into the housing 40 from the cyclone 20.

The air induction member 42 allows the air introduced into the housing 40 through the discharge port 22 of the cyclone 20 to flow below the water surface and includes a first induction plate 42a, And includes a guide plate 42b, a third guide plate 42c, a fourth guide plate 42d, a fifth guide plate 42e, and a sixth guide plate 42f.

One end of the first induction plate 42a is connected to the flow path plate 41 and is installed in parallel in the horizontal direction within the housing 40. The other end of the induction plate 42a is bent downward.

The second induction plate 42b is installed on the left side of the flow path plate 41 so as to be spaced apart by a predetermined distance and half of the entire length of the second induction plate 42b is exposed to the upper side of the water stored in the housing 40, . As a result, the air flowing downward while bumping against the flow path forming plate 41 flows into the water and then hits the second guide plate 42b and flows upward.

The third induction plate 42c is installed at a predetermined distance from the left side of the second induction plate 42b and has an upper end connected to the first induction plate 42a and a lower end connected to the water stored in the housing 40 State. As a result, the air that rises along the second induction plate 42b hits the first induction plate 42a, flows downward along the third induction plate 42c, and flows into the water.

The fourth induction plate 42d is immersed in water stored in the housing 40, and the upper end of the fourth induction plate 42d is spaced apart from the lower end of the third induction plate 42c. Air flowing into the water flows into the gap between the lower end of the third induction plate 42c and the upper end gap of the fourth induction plate 42d.

The fifth induction plate 42e is spaced a predetermined distance from the left and right sides of the third induction plate 42c and the fourth induction plate 42d and half of the entire length is exposed to the upper side of the water stored in the housing 40 The other half is kept submerged. Thus, the air introduced into the lower end of the third guide plate 42c and the upper end gap of the fourth guide plate 42d flows upwardly after hitting the fifth guide plate 42e. Then, it collides with the end of the first induction plate 42a and flows downward.

Meanwhile, in order to smoothly induce airflow, it is preferable that the portions of the second induction plate 42b and the fifth induction plate 42e, which are immersed in water, are formed in a smooth curved shape.

The sixth induction plate 42f is located on the upper side of the first induction plate 42a and has one end connected to the inner wall surface of the housing 40 and installed in parallel in the horizontal direction within the housing 40 . As a result, the air that has risen after passing between the first induction plate 42a and the fifth induction plate 42e hits the sixth induction plate 42f and then continues to rise.

The water tank 43 is provided inside the housing 40, and one wall is formed by the upper end portion of the flow path forming plate 41. The water stored in the water tank 10 may be pumped and supplied to the water tank 43 so that water is stored in the water tank 43 or water is supplied from a separate water source, .

The water stored in the water tank 43 flows down the upper surface of the flow path forming plate 41 and flows down the wall surface of the flow path forming plate 41. Since the flow path forming plate 41 faces the discharge port 22 as well as the air discharged through the discharge port 22 flows along the wall surface, a large amount of dust and foreign substances adhere to the wall surface over time, So that the dust collecting efficiency is inevitably lowered. However, since water stored in the water tank 43 flows down along the wall surface of the flow path plate 41, dust and foreign matter can be prevented from adhering to the wall surface.

The demister filter 44 is installed between the sixth induction plate 42f of the air induction member 42 and the water tub 43 to filter air that has passed through the sixth induction plate 42f. The air having passed through the sixth induction plate 42f of the air induction member 42 passes through the demister filter 44 and is discharged to the outside through a discharge pipe 51 to be described later.

The suction fan 50 sucks air inside the housing 40 through a discharge pipe 51 connected to the housing 40. That is, strong suction force acts in the housing 40 by the operation of the suction fan 50, and the air in the housing 40 is sucked strongly toward the discharge pipe 51 by the suction force.
