Description

Wet Dust Collector {Wet-type air purifier}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wet dust collector, and more particularly, to a wet dust collector which collects the harmful pollutants in the exhaust gas exhausted from various industrial facilities in a wet manner and exhausts them to the atmosphere.

In general, dust collectors are for collecting and purifying harmful exhaust gases generated in various industrial sites and emitting them to the atmosphere. Most of these dust collectors use dust filters to collect contaminants in hazardous gases from dust filters.

However, very fine contaminants are not properly collected in a conventional filter. Therefore, a filter having excellent performance should be used for higher efficiency dust collection. But these filters are, of course, quite expensive.

Therefore, in the case of using a high-performance dust collecting filter, the cost of collecting the polluted particles on the exhaust gas is excessively high, which increases the cost for removing the harmful polluted particles, which in turn increases the manufacturing cost of related products. On the other hand, in the case of using an inexpensive low-performance dust collecting filter, although it may be advantageous in terms of cost, there is a problem in that dust collection efficiency is lowered to increase air pollution.

In addition, since all of these filters, whether high-performance dust collecting filters or low-performance dust collecting filters, have a predetermined valid service life, the filter function is rapidly deteriorated after the effective service life. Therefore, since the dust collecting filter needs to be replaced periodically, there is an excessive cost for the maintenance.

The present invention is to solve the above-mentioned problems, an object of the present invention is to provide a wet dust collector that enables to purify the exhaust gas at low cost, high efficiency by filtering the pollutant particles in the exhaust gas discharged to the atmosphere by using water It is to provide.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the drawings.

1 and 2, the wet dust collecting device according to the present invention has a body 10 having a box shape with water stored therein and an upper portion thereof, and opening and closing the opened upper portion of the body 10 as shown in FIGS. The cover 20 is provided. Alternatively, other embodiments in which the body 10 and the cover 20 are integrally formed are also applicable.

And a plurality of clips 30 are installed for coupling and separation of the cover 20, the body 10, the body 10 is provided with a handle 40 to ensure the ease of movement on one side. At the bottom, a plurality of moving rollers 50 are installed.

In addition, the cover 20 is formed with an inlet port 21 through which the external exhaust gas flows into the body 10, and a separate outlet port 23 is formed at a position spaced apart from the inlet port 21. In particular, the inlet 21 is provided with a separate exhaust gas guide tube 22 extending downward.

In addition, a fan 60 is installed in the lower portion of the inlet port 21 of the cover 20 to forcibly penetrate the exhaust gas sucked from the inlet port 21 into the body 10. The fan 60 is in the form of a substantially sirocco fan with a plurality of wings 61, half of which is submerged in water and the other half is exposed to the water.

Therefore, the blade 61 of the fan 60 is developed in the water and the water. And the wing 61 is bent in the rotational direction to the end to effectively penetrate the exhaust gas of the exhaust gas.

On the other hand, the distribution hole 71 and 81 which blocks the water communication between the suction port 21 and the discharge port 23 between the fan 60 and the discharge port 23 in the body 10 and communicates through the water. The formed two partitions 70 and 80 are installed.

The partition walls 70 and 80 may include a first partition wall in which a first flow hole 71 is formed to be biased toward one side of the body 10 so that a zigzag flow path is formed between the fan 60 and the discharge port 23. 70 and a second partition wall 80 having a second flow hole 81 formed to be biased toward the other side of the body 10.

The wet dust collecting device of the present invention configured as described above needs to replace the stored water whenever necessary. To this end, the drain port 90 for draining the water stored therein is provided at the lower portion of the discharge port 23 side of the body 10. It is formed, and the on-off valve 91 for opening and closing the drain port 90 is mounted. Therefore, when replacing the used water for a certain period of time, the used water is drained through the drain hole 90, and when the new water is stored, the cover 20 may be opened and supplied into the body 10.

Hereinafter will be described the working state of the wet dust collecting apparatus according to the present invention configured as described above.

The wet dust collecting apparatus according to the present invention can be used integrally coupled to the exhaust apparatus used in the existing as shown in FIG. In other words, by purifying the exhaust gas after the final purification by wet dust collection in the final stage, it is possible to discharge the exhaust gas having a higher purification state. However, unlike this installation state, only the wet dust collecting device of the present invention can be installed and used alone, and other installations can be used.

Looking at the operation state of the wet dust collecting apparatus of the present invention, as shown in Fig. 2 and 3, the exhaust gas is first sucked through the suction port (21). At this time, the suction may be made of forced air from the outside, or may be made of natural blowing. In any case, the forced suction is performed by the fan 60 of the present invention.

In this case, the operation of the fan 60 may be performed manually or automatically, and in the case of automatic, the motor may be installed in a built-in state, or may be performed by installing the motor externally. Such embodiments may be easily implemented by those skilled in the art with reference to the embodiments of the present invention.

When the exhaust gas is sucked through the suction port 21 as described above, the sucked gas is introduced into the fan 60 through the guide tube 22. At this time, the end of the blade 61 of the fan 60 is bent at a predetermined angle in the rotation direction. Therefore, the sucked exhaust gas is forced into the water by the fan 60.

And the exhaust gas penetrated into the water moves along the water flow generated by the continuous rotation of the fan (60). That is, first, the first distribution hole 71 of the first bulkhead 70 passes through, and then the distribution path is changed in the vertical direction to pass through the second distribution hole 81 of the second bulkhead 80. The exhaust gas penetrated into the water while passing through such a distribution path is filtered by impregnating the fine polluted particles contained therein into water or by attaching it to the partition walls 70 and 80 together with moisture.

The exhaust gas passing through the second partition wall 80 is separated into the water phase by the continuous pumping force, and the separated exhaust gas is exhausted to the outside through the discharge port 23. Therefore, the exhaust gas is finally discharged as the exhaust gas in the purified state as the various fine contaminant particles contained in the exhaust gas during the inhalation through the water is purified in the water.

The water stored in the body by such a purification operation is contaminated by a large amount of fine particles over time. Therefore, it is possible to ensure optimum purification performance only by periodically replacing the stored water periodically.

Unlike the above-described embodiment of the present invention, a separate circulation passage may be formed in the body for smoother flow of the water flow, or may be applied to another embodiment by modifying the position of the suction port and the type of the fan. However, if the modified embodiments include the essential elements of the present invention, all should be considered to be included in the technical scope of the present invention.

The wet dust collecting apparatus according to the present invention is to purify the fine polluted particles contained in the exhaust gas through water, and to enable high efficiency exhaust gas purification without using a conventional expensive filter at a low cost. As a result, it is possible to achieve high exhaust gas purification efficiency.
