Description

Wet scrubber

The present invention relates to a wet type dust collector, and more particularly, to a wet type dust collector capable of efficiently adsorbing and removing more dust.

In the industrial field, many pollutants in the form of dust are emitted. In order to prevent these dusts from being discharged into the atmosphere, pollution of the surrounding environment is set up.

Dust is filtered through a dust collector, which is largely divided into mechanical and electrical. The mechanical type is divided into a wet type dust collector and a dry type dust collector. The wet type dust collector filters polluted air contained in the air by passing it through the water without discharging the polluted air directly from the industrial site so that only clean air is discharged to the air do.

Such a wet type dust collector is used in recent years because it has advantages such as no need to replace the filter and low noise because the pollutant is filtered by filtration.

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

FIG. 3 is a front view showing the wet type dust collector according to the present invention, FIG. 4 is a side view showing the wet type dust collector according to the present invention, and FIG. 5 is a plan view showing the wet type dust collector according to the present invention.

The wet dust collector according to the present invention includes a cabinet 10, a water tank 20 installed at the lower end of the cabinet 10, a housing 30 installed inside the cabinet 10, A circulation pump 50 connected to the water supply pipe 40, a downward swash plate 60 installed inside the housing 30, a water supply pipe 40 for spraying water, And a blower 70 installed in the blower.

An inlet duct 11 is installed at an intermediate portion of one side of the cabinet 10, a discharge duct 12 is installed at an upper portion of the cabinet 10, and a demister filter 13 is installed inside the cabinet 10.

One end of the inlet duct 11 is connected to the housing 30 through one side of the cabinet 10. Air containing dust, that is, compressed air flows into the interior through the inlet duct (11).

The exhaust duct 12 serves as a passage for discharging the internal air to the outside, and discharges the clean air purified through the demister filter 13 to the outside.

When the air flowing between the inner surface of the cabinet 10 and the outer surface of the housing 30 is sucked by the blower 70 and flows into the exhaust duct 12, As a portion passing through the duct 12, the air having passed through the demister filter 13 is purified and cleaned.

A transparent window 14 is installed on one side of the cabinet 10. The transparent window 14 is formed on a surface in the same direction as the transparent window 31 of the enclosure 30 to be described later so that the inside of the enclosure 30 can be confirmed. That is, the inside of the housing 30 can be seen through the transparent window 14 of the cabinet 10 and the transparent window 31 of the housing 30.

The water tank 20 not only stores water but also collects the water discharged from the nozzle 41 of the water supply pipe 40. In this water tank 20, a water level sensor 21 is installed, and a drain pipe 22 is installed.

The water level sensor 21 measures the water level of the water stored in the water tank 20. When the water level measured by the water level sensor 21 is low, the water level sensor 21 sends the signal to the controller C , And when the water level becomes equal to or higher than a predetermined height, this signal is sent to the control unit C so that the control unit C can operate the water circulation pump 50.

The overflow pipe 22 is provided to discharge the water in the water tank 20 to the outside when the water tank 20 is filled with too much water, that is, when the water level is equal to or higher than a certain height.

The bottom surface of the water tub 20 is inclined at a predetermined angle. When the water containing dust is collected in the water tank 20, the dust is accumulated on the bottom surface of the water tank 20 as sediment and collected at one corner.

The housing 30 is connected to one end of the inlet duct 11 which penetrates the cabinet 10 and enters the cabinet 10 so that the inside of the housing 30 and the inside of the inlet duct 11 communicate with each other do. Accordingly, the compressed air flowing in the inlet duct 11 flows into the housing 30. [

The housing (30) is opened at its bottom surface and closed at the other end to communicate with the cabinet (10) only through the bottom surface.

A transparent window 31 is detachably installed on one side of the housing 30 so that the inside of the housing 30 can be seen.

The transparent window 31 allows confirmation of the situations occurring inside the enclosure 30.
In addition, the housing 30 is gradually widened from the lower side of the inflow duct 11, and is gathered inward from the lower end portion thereof, so that the width of the housing 30 is reduced.

One end of the water supply pipe 40 is connected to the circulation pump 50 and is supplied with water from the circulation pump 50. Water is supplied to the water supply pipe 40 from the inside of the housing 30, A plurality of nozzles 41 are provided.

That is, the water supply pipe 40 continuously penetrates the upper surface of the cabinet 10 and the upper surface of the enclosure 30, and a certain portion thereof is located inside the enclosure 30. In this way, A plurality of nozzles 41 for spraying water downward are installed in a part of the supply pipe 40.

The circulation pump 50 supplies water to the water supply pipe 40 so that the nozzle 41 can spray water. The circulation pump 50 draws water in the water tank 20 and supplies the water to the water supply pipe 40.

That is, the water stored in the water tank 20 is supplied to the water supply pipe 40 by the operation of the circulation pump 50. When the water is sprayed by the nozzle 41, the water falls downward, ) In the process of collecting.

In the present invention, one auxiliary pump 51 having the same function as the circulation pump 50 is further provided.

The auxiliary pump 51 is connected to the water tank 20 and the water supply pipe 40 and receives water from the water tank 20 instead of the circulation pump 50 when the circulation pump 50 fails, And serves to supply water to the supply pipe 40. By this auxiliary pump 51, the operation of the wet type dust collector can be continuously operated without stopping.

The downward swing plate 60 is installed on the lower side of the nozzle 41, and the shape thereof is a pyramid shape. That is, the downward swash plate 60 has a high center and a downward inclination toward the edge.

When the downward swash plate 60 is installed inside the housing 30, both ends of the downward swash plate 60 are spaced apart from the inner surface of the housing 30 by a predetermined distance, and water particles containing dust can flow through the space .

The downward swash plate 60 has a shape of a pyramid shape as described above and the compressed air supplied to the inside of the enclosure 30 through the water jetted from the nozzle 41 and the inlet duct 11 And flows through the space between the inner side surface of the housing 30 and the downward sloping plate 60 so that the width of the flow path through which the water particles and the stagnant air flow becomes gradually narrower toward the lower side. That is, the distance between the upper surface of the downward swash plate 60 and the inner surface of the housing 30 gradually decreases toward the lower side, thereby narrowing the width of the flow passage in which the water particles injected from the nozzles 41 flow. Therefore, when the water particles and the dust air pass between the both ends of the downward swing plate 60 and the inner surface of the housing 30, the flow velocity thereof rises the highest. When the flow rate of the water particles and the dust air is increased, the amount of dust adsorbed or mixed in the water particles increases, thereby increasing the removal efficiency of dust contained in the air.

The blower 70 is installed at the upper end of the cabinet 10 to suck air in the cabinet 10 and discharge the air through the exhaust duct 12.

That is, when a suction force is generated by the operation of the blower 70, the suction force causes the air inside the cabinet 10 to pass through a space between the inner surface of the cabinet 10 and the outer surface of the housing 30 And the raised air passes through the demister filter 13 and then is discharged to the outside through the exhaust duct 12. [

The blower 70 is composed of a motor 71 and a fan 72 connected to the motor shaft of the motor 71. Therefore, when the motor shaft is rotated by the operation of the motor 71, the fan 72 also rotates to generate a suction force.

The operation of the wet type dust collector according to the present invention will be briefly described below.

When air containing a large amount of dust is supplied into the enclosure 30 through the inlet duct 11, the circulation pump 50 operates by a signal from the control unit C, (40).

The water supplied to the water supply pipe 40 is injected downward into the inner space of the housing 30 through the plurality of nozzles 41 and the downward injected water is dispersed in the air in the space inside the housing 30 The dust is adsorbed.

Thus, the water particles partially absorbing the dust and the dust air continue to flow downward along the gradually narrowing path between the inner surface of the housing 30 and the downward swash plate 60.

The water particles continuously flowing downward reach the both ends of the downward swash plate 60 and flow at the highest speed. At this point of maximum speed, dust contained in the swash air is more contained in the water particles.

Thereafter, the water particles including the dust continue to flow downward and are collected in the water tank 20. When the water is collected in the water tank 20, the dust contained in the water is deposited on the bottom surface of the water tank 20 to become a precipitate.

In the meantime, when the above-described operations are performed, the blower 70 operates to generate a suction force. After the air in the cabinet 10 is raised by the suction force, the air passes through the demister filter 13, Clean air cleaned by the mister filter 13 is discharged to the outside through the discharge duct 12.
