Advantages and features of the present invention, and a method of achieving them, will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in a variety of different forms, and only these embodiments allow the disclosure of the present invention to be complete, and common knowledge in the technical field to which the present invention belongs It is provided to fully inform the possessor of the scope of the invention, and the present invention is defined by the description of the claims.

On the other hand, the terms used herein are for the purpose of describing the embodiments and are not intended to limit the present invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. As used herein, “comprises” and/or “comprising” refers to the presence of one or more other components, steps, operations and/or elements in a referenced element, step, operation and/or element. or addition is not excluded. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic configuration diagram of a hazardous substance removal device according to the present invention, and FIG. 3 shows a bubble tank of the hazardous substance removal device according to the present invention, and is a view for explaining a process in which air bubbles are generated.

2 and 3, the hazardous material removal device 100 according to the present invention, the hood 10, the dust and oil vapor removal unit 20, the bubble tank 30, the air pump 40 and the washing tower (50).

The hood 10 is to inhale dust, oil vapor and odor.

The dust and oil vapor removal unit 20, the front end is connected to the rear end of the hood 10, to remove dust and oil vapor.

In addition, the dust and oil vapor removal unit is capable of removing dust and oil vapor by stacking a plurality of nonwoven fabrics, and should be replaced after proper use.

The bubble tank 30 has a front end connected to the rear end of the dust and oil vapor removal unit 20 , and air bubbles are generated to secondarily remove odors and oil vapors.

In addition, 1/2 to 2/3 of the bubble tank 30 is filled with water, a plurality of washing balls 60 are filled in the water, and when the water is buffered or insufficient inside the tank, air bubbles are generated. This will not be done smoothly.

Here, the washing ball 60 has a spherical shape and may have the same size, but more preferably have different sizes to facilitate mutual collision, and form a plurality of protrusions or grooves on the surface of the air It may be possible to facilitate the creation of bubbles.

When the size of the air bubble is made various, the surface area of the air bubble is expanded, so that more odors and oil vapors will be easily adsorbed to the air bubble.

In addition, a water supply port 31 is formed in the upper portion of the bubble tank 30, a water outlet 32 is formed in the lower portion, and a solenoid valve is installed at the water supply port 31 and the water outlet 32. The amount of water installed inside the tank is opened and closed by the sensor to maintain a certain amount of water.

In addition, a perforated network 33 is installed inside the rear end of the bubble tank 30 to prevent the washing balls 60 from being transferred to the air pump 40 side, and only air from which odors have been removed passes through. .

In addition, a fine bubble generating part 34 is formed on the bottom surface of the bubble tank 30, and the fine bubble generating part 34 is made of an arc surface, and a plurality of through holes are formed on the arc surface to form air bubbles. may facilitate the formation of

The air pump 40 has a suction port 41 connected to the rear end of the bubble tank 30 to repeatedly supply and exhaust air to the bubble tank 30 .

The washing tower 50 has one end connected to the outlet 42 of the air pump 40, and discharges the air that has passed through the air pump 40 to the outside, and supplies water to remove dust and oil vapor. The harmful substances that cannot be removed from the rejection 20 and the bubble tank 30 are finally removed.

The harmful substance removal device 100 according to the present invention configured as described above is installed in an industrial site, particularly a place where dust, oil vapor, and odor are generated a lot, such as a fiber tender machine or a plastic melting facility.

The dust, oil vapor, and odor generated in the industrial field are sucked in from the hood 10 and then pass through the dust and oil vapor removal unit 20, and are formed by a plurality of nonwoven fabrics forming the dust and oil vapor removal unit 20. Dust and a certain amount of oil vapor are removed.

In addition, harmful substances that have passed through the dust and oil vapor removal unit 20 pass through the bubble tank 30 , which supplies or exhausts air inside the bubble tank 30 by the operation of the air pump 40 . is repeatedly performed, and as the air bubbles and water generated in the micro-bubble generating unit 34 flow together with the washing ball 60, more and more air bubbles are formed.

The washing balls 60 have different sizes and the bottom surface 34 of the bubble tank 30 has a hemispherical shape, so it is easy to form air bubbles. , and the surface area of the air bubble expands to adsorb odors and oil vapors secondary.

In addition, water from the bubble tank 30 is supplied through the water supply port 31 , and water from which odors and oil vapors are removed is discharged to the outside through the water outlet 32 .

In addition, the air that has passed through the air pump 40 is removed from dust, oil vapor, and odor, but harmful substances that may still remain are finally removed from the washing tower 50 and discharged to the outside.

Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, it will be understood by those skilled in the art that various modifications and other embodiments are possible.
