FIG. 2 is a perspective view of an exhaust filtration apparatus according to the present invention. FIG. 2 is a perspective view of an exhaust filtration apparatus according to an embodiment of the present invention. FIG. 2 is a perspective view of a filtration apparatus including multiple filtration layers and a ventilation fan, And is provided with a body part 100, a filtration layer part 200, a pan part 300, and a cover part 400.

4 is a cross-sectional view of an exhaust filtration apparatus according to the present invention. Referring to FIG. 3, the body 100 is formed in a vertically penetrating shape, And a lower part is attached to the exhaust port 1 and includes a body 110, a hermetic member 120, a mesh part 130, and a support part 140, do.

Here, the body 110 occupies most of the body 100 and is formed in a vertically penetrating shape to provide a space in which the structures of the filtration device are installed. Since the exhaust port 1 is circular, the body 110 is formed in a circular shape. When the exhaust port 1 is applied to a square exhaust port 1, the body 110 is formed into a square shape. .

In this case, the size of the body 110 can be variously applied, and since the diameter of the existing exhaust port and the new exhaust port is mainly 75 to 100 mm, the size of the body 110 may be applied to the diameter of the exhaust port.

In order to install the exhaust filtration apparatus 10 of the present invention in the exhaust port for the sewage treatment facility, the size of the body 110 is attached to the exhaust port for the wastewater treatment facility, because the exhaust port for the sewage treatment facility is larger than the general exhaust port. Apply as much as possible.

Therefore, in order to install the exhaust filtration apparatus 10 of the present invention in exhaust ports of various sizes, the size of the body 110 may be applied to the diameter of the exhaust port to be installed.

4, the body 110 includes a coupling protrusion 111, a coupling protrusion 112, and a support protrusion 113. The coupling protrusion 111 protrudes from the bottom of the body 110, And the connector 112 is attached to the upper portion of the exhaust port 1 by a protruding connection protrusion 111 to a space formed in the lower portion of the interior of the body 110 .

 The supporting jaws 113 are located at the upper portion of the connecting hole 112 formed in the lower part of the inside of the body 110 and protrude inward to be smaller than the connecting hole 112 to support the filtering layer 200 to be.

The hermetic member 120 is inserted into the coupling hole 112 to stably maintain the coupling between the body 100 and the exhaust port 1. The hermetic member used in this case is a general hermetic member.

The mesh part 130 is coupled with the outside of the filtration layer part 200 inserted into the body 110 to prevent intrusion of external organisms such as insects into the filtration layer part 200, 200, and is composed of a first mesh 131, a second mesh 132, and a mesh pipe 133.

At this time, the hole diameter of the mesh member applied to the mesh unit 130 may be in the range of 1 to 10 mm, but preferably a fine mesh member of 5 mm or less is preferably applied.

3 and 4, the support part 140 is a kind of support part formed on the upper side of the body 110 as a kind of support, and the body part 100 and the lid part (400) to be spaced apart.

The support portion 140 is formed with a coupling protrusion 141 in the form of a male thread and has a coupling groove 415 formed in the form of a female screw at a certain depth below the middle portion of the lid 410 of the lid portion 400 So that the body 100 and the lid 400 are separated from each other.

A discharge space 142 is formed between the plurality of support portions 140 and the support portion 140 so that the air discharged from the discharge port 1 is discharged to the outside by the rotation of the fan portion 300.

3 and 4, when the filtration layer 200 is inserted into the inner space formed by the first mesh 131 and the mesh pipe 133, the first mesh 131 is separated from the filtration layer 200 and the mesh pipe 133 protects the side surface of the filtration layer 200. When the second mesh 132 covers the upper portion of the filtration layer 200, the mesh 130 is completely coupled .

At this time, the mesh part 130 uses a metal material or a synthetic resin having excellent mechanical properties and corrosion resistance.

The filter layer part 200 is installed inside the body part 100 and removes the odor of the air exhausted from the exhaust port 1 to purify the filter part 200. The filter layer part 200 includes charcoal, pine charcoal, bamboo charcoal, And the like. Charcoal may be used in any kind of charcoal. The type of charcoal is not limited to this, and any known charcoal may be used, and the charcoal may be replaced.

Further, at least one of a loess ball, a ceramic ball, an ocher ring, a ceramic ring, a nonwoven fabric, a synthetic resin fiber, a glass wool, a copper foil and a sponge may be applied as a filter medium, and preferably two or more of them can be applied. Do.

At this time, filtration efficiency is better because two or more filtration layer portions 200 are preferably applied, and the replacement cycle is flexible depending on the kind of the applied filter medium, the usage state or the use environment, It is preferable to replace the filtration layer 200 when the odor becomes worse even after two years since the exhaust filtration apparatus 10 of the present invention is applied to the exhaust port 1. [ The method of replacing the filtration layer part 200 is described with reference to FIG.

The first filtration layer 210 and the second filtration layer 220 may be formed of a first filtration layer 210 and a second filtration layer 220, And the odor of the air discharged from the exhaust port 1 is removed step by step according to characteristics of the applied filter medium to purify the air.

At this time, the filter material applied to the first filtration layer 210 also varies, but the charcoal is preferentially applied in the present invention.

Here, the charcoal has a lot of fine holes and has a large specific surface area (about 300 m 2 per 1 g of charcoal). The function of the charcoal hole is to remove the bad bacteria by the inhabiting microorganisms, to function to remove bad odor, Humidity control function.

Meanwhile, the recycled charcoal extracted from industrial or municipal wastes may be applied to the applied charcoal for cost reduction and recycling of resources, and bamboo charcoal, bamboo charcoal and charcoal may be applied in a double manner.

Here, the efficacy of bamboo charcoal can be substituted for the charcoal which has been widely used since it has an anion and far-infrared ray emission, electromagnetic wave shielding, odor removal and air purification, water purification, antibacterial, mineral supply and humidity control.

Also, bamboo charcoal replaces charcoal because it has a higher adsorption rate of heavy metals, electromagnetic wave shielding effect, and antimicrobial effect. According to clinical data from the National Forestry Academy, the removal rates of heavy metals were -82%, -47%, -42%, and -92%, respectively, indicating that bamboo charcoal had an excellent effect on the removal of heavy metals .

In addition, bamboo charcoal is known to have excellent antimicrobial activity. The bacterial reduction rate was 96.1% for E. coli and 97% for P. aeruginosa. When the bamboo was charcoal made at 800 ~ 1,000 ℃, the electromagnetic wave shielding rate was 90 ~ 99.9% The shielding effect proved to be excellent. In addition, since bamboo charcoal is made in bamboo at high temperature over 800 ℃, it is aseptic for a while after it is formed, and it contains almost no organic materials and only 2 ~ 3% of alkaline components such as calcium and potassium.

In particular, bamboo charcoal is known to excel in the mind and body stabilization effect and deodorization effect at the time of sleeping by the release of anion, and it is said that the action of bamboo charcoal is very excellent in promoting the metabolism of human body by a large amount of far- .

On the other hand, charcoal is an odorless, tasteless, harmless, and inexpensive, and it is also effective in preventing and reducing oxidation, generating anion, alkalizing acidic substances, emitting far infrared rays, controlling humidity, filtering effect, deodorizing effect, .

In addition, charcoal is medically effective as an adsorbent, antidote, analgesic, antipyretic, anticancer, etc. It utilizes the excellent adsorption of charcoal, rather than the special medicinal ingredient of charcoal.

Particularly, the fine porosity of charcoal adsorbs debris and decayed gas of corrupt proteins and fat in the intestines, and adsorbs pesticide components and heavy metals remaining in fruits and vegetables.

In addition, charcoal adsorbs and removes harmful components such as coloring matter, food additives, artificial seasonings, etc. of processed foods, and charcoal powder removes toxic components from inside the body, so that the function of liver and kidneys to detoxify is activated, There is no antidote to surpass charcoal as a single material.

Therefore, charcoal may be preferentially applied to the filter material applied to the first filtration layer 210, and bamboo charcoal or bamboo charcoal and charcoal may be applied in a double-layer manner.

However, in the present invention, the loess balls are preferentially applied, and the size of the loess balls applied is 0.1 to 200 mm, preferably 10 to 200 mm. .

Here, 200 million microorganisms per 1 g of loess are alive, and various harmful components are spontaneously decomposed to remove odors, and deodorization, insect pest control, and prevention of fungi are effective.

Therefore, when the odorous gas is passed through the clayey soil, the odorous components of the gas are primarily dissolved in the adhered water and capillary water of the clayey soil layer. Secondly, the biochemical degradation by the microorganisms contained in the clayey soil particles and the chemical reaction So that the clay layer reduces or eliminates the odor component of the gas through a stepwise and complex reaction.

As a representative example, the mechanism of deodorization of ammonia is as follows. This action is called ionization of ammonia, and ammonia ions are decomposed by nitrification action as shown below.

NH ³ + H ₂ O → NH ₄ OH → NH ⁺ ₄ + OH ^-

2NH ⁺ ₄ + 3O ₂ ? 2NO ² + 2H ₂ O + 4H ⁺ + energy

2NO ² + O ₂ ? 2NO ^-3 + energy

On the other hand, the loess ball is formed by mixing a wood component of a carbon component into a filter material made of clay mineral, which is a clay mineral. When the air discharged from the exhaust port 1 passes through the loess ball, It is purified through biochemical degradation and complex action by chemical reaction by soil component of loess ball.

Here, organic material materials are mixed in order to develop pores on the surface of the loess balls to improve the filtration ability due to enlargement of the porosity and the adsorption ability according to the enlargement of the activation ability of the carbon components, and the organic material materials are mixed with wood, , Wastes of crushed waste wood, rice husks, bark, rice straw, activated sludge, dried food waste and compost, other organic materials and non-toxic organic wastes are selectively used.

Therefore, when a charcoal-based filter medium is applied to the first filter layer 210 and a loess ball is applied to the second filter layer 220, the first filter layer 210 functions as a filter It is possible to purify the air efficiently because the sulfur compound such as hydrogen sulfide is removed and the air odor is removed from the second filtration layer 220.
