Description

Apparatus for removing pollution matter}

The present invention relates to an apparatus for removing pollutants, and more particularly, to an apparatus for removing pollutants installed at an exhaust port of an industrial facility and an incinerator.

Recently, harmful exhaust gases and fly ashes, which are inevitably generated in industrial facilities and waste incinerators, have been recognized as one of the representative pollutants that pollute the environment. to be.

Therefore, pollution of heavy metals by exhaust gases and fly ash generated in industrial facilities and incinerators and air and soil contamination by acid rain is becoming more and more serious. In particular, in recent years, a lot of garbage incinerators are being constructed because the limit of landfills generated from industrial facilities and households has been reached. However, it was analyzed that 95% of the fly ash generated in the waste incinerator was dioxin.

Generally, dioxin refers to a general term for polychlorinated dibenzoparadioxin (PCDD) having 75 kinds of isomers and polychlorinated dibenzofurans (PCDF) having 135 kinds of isomers.

Fly ash containing a large amount of dioxin has a very bad effect on residents near the incinerator. Looking at the type, dioxins in the soil, breast milk, hair roots, blood, etc. contains dioxin, and the milk in the ranch has been shown to contain a significant amount of dioxin. Looking at the toxicity of dioxin reported so far, a large number of animal experiments have been reported to cause a lot of deaths, weight loss, skin diseases, liver disorders, etc. are known to be carcinogenic substances that promote cancer in particular.

As such, a variety of methods and devices have been developed to recognize the seriousness of damage caused by exhaust gases and fly ash from industrial facilities and waste incinerators, and to reduce the damage caused by them, but are insufficient to reduce the damage caused by them. to be. On the other hand, in order to reduce the damage caused by the exhaust gas and fly ash generated in industrial facilities and incinerators is the most chimney is installed. However, chimneys are not only very expensive to install, but also require exhaust gas and fly ash in the atmosphere, so a separate purification device is required. Therefore, the chimney is not as effective as the cost of the installation. In addition, high chimneys are one of the biggest factors that undermine the aesthetics of the city.

Therefore, the technical problem to be achieved by the present invention is to provide a contaminant removal device that can effectively remove contaminants such as exhaust gas and fly ash without the need for a chimney with less utility.

Furthermore, a jet nozzle may be further provided at the outlet of the water flow pipe or the inhibitor transport pipe.

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

1 is a schematic view for explaining a pollutant removal apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an air blower 100 is installed in an exhaust port 11 of an industrial facility and a waste incinerator 10 without a high chimney in the industrial facility and the waste incinerator 10. At this time, the air blower 100 is discharged from the exhaust port 11 of the industrial facility and the waste incinerator 10 at a pressure higher than the inhibitor outlet pressure in the inhibitor supply pipe 620 and the water outlet pressure in the water supply pipe 610 which will be described later. Forced discharge of contaminants

The pollutant transport pipe 200 is installed at the outlet of the air blower 100. The pollutant transport pipe 200 is provided by bending at least one time so that the outlet 210 faces downward.

A reservoir 300 is installed at the outlet 210 side of the pollutant transport pipe 200. At this time, the reservoir 300 into which the pollutant flowing out through the outlet 210 of the pollutant transport pipe 200 is introduced, the inlet 310 of the reservoir 300 provided at the upper end is the pollutant transport pipe 200. The outlet 210 is installed to be spaced apart from a predetermined distance. At this time, the water tank 300 is stored in the water tank 300 by about 70 to 80% of the height of the overall height of the water tank 300 so that the water is prevented from overflowing due to the discharge pressure of the contaminants, and the water tank 300. The upper surface of the filter 400 made of a nonwoven fabric or the like is installed to be detachable.

The reservoir 300 is provided with a pump 510 for pumping the water 20 in the reservoir 300. The pump 510 is provided with a water flow pipe 610 for transferring the water pumped by the pump 510 into the pollutant transport pipe 200, and an injection nozzle 710 is installed at the outlet side of the water flow pipe 610. do.

Therefore, the contaminants forcedly transported by the air blower 100 are mixed with the water sprayed from the spray nozzle 710 installed at the outlet side of the water flow pipe 610 and flowed into the reservoir 300. Therefore, the contaminants discharged from the industrial facility and the waste incinerator 10 are not scattered and flowed into the reservoir 300 so that the contaminants can be more efficiently removed. On the other hand, by installing the filter 400 on the reservoir 300, it is possible to mitigate the contamination of the water 20 in the reservoir 300. In addition, although not shown, a water supply device for supplying water to the reservoir 300 and a water drainage device for draining the contaminated water are provided separately.

On the other hand, the pollutant removal device of the present invention, the inhibitor supply device 520, the inhibitor supply pipe 620, and the inhibitor supply pipe 620 to prevent the production of dioxin from the exhaust gas and fly ash discharged from the industrial facility and waste incinerator 10 It is further provided with a spray nozzle (720) installed. At this time, the inlet of the inhibitor supply pipe 620 is connected to the inhibitor supply device (520). And, the outlet of the inhibitor supply pipe 620 is located inside the pollutant transport pipe 200, the inlet of the pollutant transport pipe 200 and the flow of water pipe 610 located inside the pollutant transport pipe 200 It is located between the outlets.

As an inhibitor for inhibiting dioxin production, basic compounds, sulfur compounds, or amines are used. In general, dioxin is generated by the conversion of small organic molecules such as chlorphenol or pentachlorphenol to polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran by adsorption to fly ash. At this time, the chlorine in the chemical structure of polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran is due to exhaust gas such as metal chloride or HCl in fly ash. On the other hand, transition metals such as copper or iron catalyze the production reaction of polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran as described above.

Therefore, by introducing a basic compound such as NH ₃ , CaO, KOH, or Na ₂ CO ₃ , fly ash is alkalinized to reduce the production of polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran. In addition, when a sulfur compound such as CS ₂ or thiophene is added, transition metals and sulfur compounds which catalyze the production of polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran form a complex compound. The production of paradioxin or polybenzoic dibenzofuran can be suppressed. In addition, when amines such as ethanolamine or triethanolamine are added, they also form complexes with transition metals, thereby inhibiting the production of polychlorinated dibenzoparadioxin or polychlorinated dibenzofuran.

In the present invention, only one injection nozzle installed in the water supply pipe and the inhibitor supply pipe is illustrated, but a plurality of nozzles may be installed depending on the capacity of the pollutant and the supply of water and the inhibitor.

As described above, according to the contaminant removing device of the present invention, the contaminants are mixed with water and introduced into the reservoir, so that not only the contaminants can be more easily removed, but also environmental pollution due to the scattering of contaminants is prevented. can do.

In addition, the need for a high chimney can reduce the cost of building industrial facilities and incinerators.

Furthermore, since an inhibitor capable of inhibiting the production of dioxins can be easily added, the damage caused by dioxins can be reduced.

The present invention is not limited only to the above embodiments, and it is apparent that many modifications are possible by those skilled in the art within the technical spirit of the present invention.
