Description

Wet Dust Collector

The present invention relates to a wet dust collecting device, and more particularly, a plurality of porous disks and shafts rotated inside the casing to form a water film on the disk by rotating water, so that dust in the air can be quickly collected without re-splashing. It is to provide a wet dust collector.

As air pollution emission regulations are tightened due to the seriousness of air pollution, there is an urgent need to develop low-cost, high-efficiency dust collectors for replacing and supplementing air pollution prevention facilities installed in each industry. The development is actively progressing at home and abroad.

Currently, high-efficiency dust collectors are widely used as filter dust collectors and electrostatic dust collectors, but each has advantages and disadvantages.

Electrostatic precipitators have the advantage of being able to handle large flows of air without significant loss of pressure and are very simple in structure and easy to maintain and repair. However, the existing researches on electrostatic precipitators depend only on electrical power. In order to maintain high efficiency, there is a problem that the size of the device is accompanied.

The most widely used filter dust collector in the industry has high dust collection efficiency and wide range of application, but has problems of high pressure loss and maintenance due to the use of filter media.

In order to compensate for this, there is a multi-stage porous plate system of the Patent No. 403287, which the inventors have selected and patented. However, the prior patent has a problem that it is difficult to maintain high efficiency for a long time due to the re-scattering of the collected dust. In this case, there are disadvantages in that the dust collection efficiency decreases due to re-spreading of the dust collected on the plate surface and dust removal equipment for dust removal is required.

In this regard, the inventor has filed a patent application for a wet multilayer multi-stage porous plate dust collector (application number: 10-2012-0098070).

That is, the prior patent application collects fine dust, dust, and harmful gas in a contaminated air stream including water spray for spraying water onto the contaminated air stream installed inside the casing and sucked by the suction fan, and water passing through the water spray. A plurality of plates are installed at intervals in the vertical direction, a reverse flow space and a black box are formed alternately between the plate and the neighboring plate, and horizontally formed on the plate to flow the air flow into the black box It has a supply tube and an outlet hole formed in the plate to flow back the air flow from the black box to the back flow space at the rear side, so that it can be applied to low pressure loss (200 mmH ₂ O or less), high toxic substance removal efficiency, and large flow rate. It was possible to provide a wet dust collecting device capable of miniaturizing the device and requiring no demister installation.

However, the present inventors have not been satisfied with the above-described prior patent application, and have focused on improving the efficiency of preventing the re-scattering of collected dust more efficiently.

In the wet dust collector provided by the present invention to solve all the problems of the conventional wet dust collector,

The present invention does not require the installation and replacement of the demister, to minimize the pressure loss as possible, to minimize the power consumption, miniaturization of the device, to provide a high efficiency wet dust collector.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention.

1 is a cross-sectional view showing a first preferred embodiment of the wet dust collector provided in the present invention.

The wet dust collector 1 of the present invention includes a casing 2 made of a sealed enclosure for collecting dust in the air, and an air inlet pipe 3 through which air, including dust, can flow into both sides of the casing 2. ) And the outlet pipe (4), which can only flow out of the air after the dust is collected, respectively.

Then, the shaft 5 is installed in the casing 2 in the horizontal direction, and the casing 2 is connected to a drive source 6 such as a motor from the outside of the casing 2 so that the shaft 5 can be rotated at a predetermined rotation speed. .

Of course, a variety of power transmission mechanisms such as spur gears, belts and belt pulleys, chain sprockets and chains for power transmission may be selectively installed between the shaft 5 and the motor as the driving source 6. Is a general power transmission method can be applied as it is. The example shown is the case of using a spur gear.

The shaft 5 is axially fixed to the plurality of disks 7 next to each other. In the illustrated example, five disks 7 are installed, but the number of installations of the disks 7 may be reduced, and a plurality of holes 8 are provided in the disk 7 in the air passage direction. It is formed penetrating in the horizontal direction.

The hole 8 is preferably formed in a tubular shape to form a jet stream when the air is discharged.

However, the holes 8 of the disk 7 are formed so as to deviate from each other in the horizontal direction with the holes 8 of the disk 7 which are adjacently fixed to the shaft 5.

This will be described later, but when the air is introduced into the casing (2) through the inlet pipe (3) and out through the outlet pipe (4) is moved through a plurality of holes (8) formed in the disk (7), The air passing through the holes 8 of the first disk 7 inertically collides with the next second disk 7, and dust in the air is collected on the surface of the disk 7 on which the water film is formed. This is to pass through the holes 8 of the next 3, 4, 5 .. disk 7 sequentially through the holes 8 formed in 7), and finally to flow out toward the outflow pipe 4.

As the air passes through the plurality of disks 7 and the plurality of holes 8 formed in the disks 7 sequentially, the dust in the air is collected in the sequentially stored water.

To this end, water is introduced into the casing 2 through the input pipe 9, and the injected water is about half or less of the total height of the casing 2.

When a large amount of dust is collected in the water using a predetermined time, which is introduced through the inlet pipe 9 of the upper casing 2 and is in a turbid state, it is drained through the discharge pipe 10 formed in the lower casing 2 and clean water is again Allow input.

On the other hand, since the air may pass through the space formed between the casing (2) and the disk (7), the blocking wall (11) for blocking it is provided respectively.

The barrier wall 11 and the disk 7 are installed with a slight clearance so that the air including dust does not pass while the disk 7 does not interfere with the rotational drive.

In the illustrated example, the casing 2 constituting the wet dust collecting device 1 has a rectangular shape, and the disk 7 has a disc shape, which is axially fixed to the shaft 5 to rotate. A plurality of holes 8 are formed in 7 to allow air to pass through.

A blocking wall 11 is installed between the disc 7 and the casing 2 so that air does not pass through it.

Of course, the casing 2 may be configured as a cylinder, a polygon, and the like instead of a rectangle.

3 is a cutaway view of the working state of the A-A line showing some other embodiments of the disk 7 in the wet dust collector provided in the present invention.

That is, when water is stored in the casing 2 and the disk 7 is slowly rotated at a predetermined rotation speed by the driving source 6, the stored water moves upward along the surface of the disk 7. As a result, the surface of the disk 7 is rotated while wet.

The disk 7 itself rotates as it passes through the water stored under the casing 2, so that the surface is wetted with water, but the water stored inside the casing 2 is more smoothly upward when the disk 7 rotates. In order to maintain the water film on the front surface of the disk 7, a plurality of protruding vanes 12 are formed on the surface of the disk 7 so that the vanes 12 rotate in the direction of rotation of the disk 7. By moving the water to form a water film on the upper part of the disk 7, that is, the surface of the disk 7 through which air collides, dust is collected in the water film formed on the surface of the disk 7 and moves downwards. To be captured.

4 is a cross-sectional view of an operating state of the wet dust collecting apparatus 1 of the present invention, and FIG. 5 is an enlarged cross-sectional view of the main portion.

That is, air including dust is introduced into the casing 2 through the inlet pipe 3 formed on one side of the casing 2.

At this time, if the suction fan (not shown) is connected to the inlet pipe (3) side, or if the discharge fan (not shown) selectively installed on the outlet pipe (4) side, air is introduced into the casing (2) to the outlet pipe (4). Outflow is made to the side) and dust contained in the air is sequentially captured on the surface of the plurality of disks 7 on which the water film is formed, and is collected in the stored water.

More specifically, the air introduced into the casing 2 inertically collides with the surface of the disk 7, where the air passing through the hole 8 sequentially collides with the surface of the next-stage next disk 7 installed adjacently. Will be.

Therefore, whenever air passes through the holes 8 of the disk 7, dust is collected by the water film formed on the surface of the disk 7, and is deposited in water instead of being re-spread and formed on the plurality of disks 7. The air flowing out through the hole 8 and into the outflow pipe 4 is only outflowing clean air.

When the water stored in the casing (2) is dusted to some extent, when the water becomes turbid, the discharge pipe 10 can be opened and discharged, and then clean water can be introduced through the input pipe 9 to continue the dust collecting operation. .

In the wet dust collecting apparatus 1 of the present invention, which can be configured as described above, a plurality of disks 7 rotated by a driving source 6 are installed in casing 2 in which water is stored, and the disk ( In the 7), a plurality of holes 8 are formed to deviate from the holes 8 of the adjacent disks 7 so that air sequentially passes through the holes 8 of the disks 7 and the water film is formed. By collecting dust in the air on the surface and allowing it to be deposited and collected in the water, it is possible to eliminate the problem of collected dust re-spread again, thereby maximizing the dust collection efficiency.

Although described and described in connection with a preferred embodiment for illustrating the configuration and principle of the wet dust collector provided in the present invention as described above, the present invention is not limited to the configuration and operation as shown and described as such. .
