Generally, toxic substances generated in large quantities in combustion gases such as combustion chambers of various industrial sites, bathhouses, thermal power plants, or incinerators for incineration of household wastes, for example, VOC (ethylene, methanol, prohmaldehyde, trimethylbenzene). In addition to the carcinogenicity, substances and dioxins designated by the Ministry of Environment as regulated VOCs are known to be carcinogens. In addition to carcinogenicity, they cause fatal damage to each part of the human body and are also a cause of birth defects.

In addition, dust and various foreign substances generated during soot and combustion also have a great adverse effect on the human body and ecosystem and cause various medical diseases.

The toxic substances and foreign substances not only severely destroy the natural environment but also cause abnormal environmental changes, and are causing a great deal of damage to the ozone layer.

Therefore, technologies for removing air pollutants from exhaust gas have been researched and developed in various forms, and various devices have been proposed that have various air pollution prevention facilities and discharge them after treating harmful components.

In addition, a filter 43 for finally filtering water vapor is provided at the upper end of the exhaust part 40.

Let us look at the dust collecting process of the dust collecting apparatus according to the embodiment of the present invention configured as described above. First, the circulating pump 21 is operated to pour the purified water under the collection chamber 10 and spray it through the injection port 22a of the horizontal tube 22 to open the gas and the purified water passage hole 31 of the adsorption part 30. Falling down to the bottom in the form of a stream of water through the upper surface of the adsorption portion 30 is a state in which the purified water is accumulated to a certain height.

At this time, the purified water injected downward through the injection port 22a of the horizontal pipe 22 falls down about 90% through the gas and the purified water passage hole 31 of the adsorption part 30, and the remaining 10% is adsorbed. There is a standing on the upper surface of the part 30, the purified water level at this time maintains approximately 3 ~ 5mm.

In this state, since the blower 12a of the gas suction pipe 12 starts to operate, the polluted gas is sucked into the collection chamber 10. For example, the pollutant gas suction amount at this time may be 426 m 3 / h, and the pressure may be 75 mmAq. The polluted gas sucked in this way is ejected to the surface of the purified water in the collection chamber 10, so that soot, dust, and odor are primarily adsorbed and removed.

As described above, the contaminated gas that hits the surface of the purified water in the collection chamber 10 in the state where the purified water falls in the form of a water stream through the gas of the adsorption unit 30 and the purified water passage hole 31 is blown by the blower 12a. Due to the pressure continuously supplied to the suction, the stream of purified water is thinned, and soot, dust and odor in the polluted gas are adsorbed and removed while the polluted gas in the collection chamber 10 rises upward.

At the same time, the contaminated gas passes through the gas and the purified water passage hole 31 of the adsorption part 30 while the contaminated gas pressure in the collecting chamber 10 is always maintained constant. At this time, bubbles are generated in the purified water on the upper surface of the adsorption unit 30 while the polluted gas passes, and the bubbles generated in this way are kept up to the bubble blocking unit 60 on the upper side of the adsorption unit 30. Will be. The foam blocking part 60 is provided with a fine mesh network to block bubbles from continuously rising.

While passing through the bubbles on the adsorption unit 30 in the collection chamber 10, soot, dust, and odor of the polluted gas are adsorbed and removed in a third manner.

As described above, the polluted gas passing through the bubbles of the adsorption part 30 can adjust the amount of water vapor discharged to the exhaust part 40.

The gas in the form of water vapor passing through the foam blocking part 60 is blocked at the lower end of the exhaust part 40 by the water vapor blocking flat plate 41, and the water vapor is firstly removed while being guided to the side of the edge portion thereof. The gas is discharged to the exhaust unit 40 through the gas through hole 41a formed at the side of the flat plate 41. At this time, since the upper end of the exhaust part 40 is bent like an S-shape toward the upper part, water vapor in the secondary gas is filtered by the exhaust part 40 inner surface, and finally, at the filter 43 at the upper end of the exhaust part 40. Thirdly, water vapor is filtered so that only the purified gas is discharged to the outside.

In this way, the impurities of the exhaust gas are filtered as much as possible, and the purified gas can be discharged to the outside. If the purified water is contaminated for a long time, the operation of the circulation pump 21 is stopped and the contaminated purified water is discharged to the contaminated water outlet ( 11) to the outside and supply the new clean purified water on the filter 43 of the exhaust section 40, or separate the exhaust section 40 of the upper portion of the collecting chamber 10, and then supply it to the collecting chamber 10. .

At this time, the amount of purified water supplied to the collection chamber 10 can be confirmed through the level gauge 14, and when supplied above a predetermined level is discharged through the water level control outlet 13 to maintain the correct level of purified water.

On the other hand, to clean the collecting chamber 10, the adsorption unit 30, the bubble blocking unit 60, and the like, the exhaust unit 40 is separated from the collecting chamber 10 and the upper inner surface of the collecting chamber 10 is disposed. Separates the fixing member 70 assembled in the upper portion and lifts the foam blocking portion 60, and then separates the elbow 23 from the purified water circulating portion 20 together with the horizontal pipe 22 at the lower portion thereof. Each part 30 can be rolled out to perform each cleaning.

As described above, the dust collector according to an embodiment of the present invention is to circulate the purified water continuously in the collection chamber to purify the polluted gas introduced into the collection chamber during the downfall from the adsorption unit, and then the adsorption unit Through the secondary purification, the third purification in the foam blocker and the bent shape of the exhaust and the fourth purification by the filter, impurities are removed from the polluted gas, thereby minimizing the number of filters to remove impurities through the basic simple structure. Savings can be eliminated as well as filter management costs.
