The present invention relates to a noxious gas filtration device, and more particularly to a noxious gas filtration device having a gas-liquid separation means that can filter the mist generated in the noxious gas filtration process.

If harmful gases from various industrial facilities, such as conventional sewage treatment plants, sludge treatment facilities, and waste disposal facilities, are released into the atmosphere, odors are generated and damage to the living environment of nearby residents. It is a threat.

Therefore, in order to prevent damage caused by harmful gases, harmful gases are collected and purified after being discharged to the atmosphere.

Hazardous gas treatment methods include physical methods of adsorption using activated carbon and biological methods of decomposition using microorganisms. The components, composition and concentration of hazardous gases to be treated, and secondary pollution treatment measures are comprehensively reviewed. The treatment facility is selected.

Here, the so-called biofilter deodorizer using microorganisms has a structure having a carrier therein, and filters harmful gases in a manner of sequentially performing a humidification using a humidifier and a deodorization using a carrier.

According to the humidification effect, dust contained in harmful gases is mixed with water and settled, and water-soluble components such as ammonia are removed. According to deodorization, odorous components contained in harmful gases are decomposed by a microorganism inhabiting a carrier.

In addition, since the microorganisms inhabiting the carrier need appropriate moisture for its growth, the deodorizing space maintains a state in which water necessary for microbial growth is continuously supplied.

Therefore, according to the prior art, the harmful gas contains a large amount of water in the process of humidification, and even in the process of deodorization, by contacting the carrier containing the moisture, the water content is increased, and finally the mist mixed with the gas and fine liquid droplets. It is discharged to the outside in the (mist) state.

Therefore, when the temperature of the outside air is quite low, such as winter season, the gas after filtration is discharged in the mist state, and condensation forms easily in contact with the outside air having a relatively low temperature, thereby forming water droplets.

In addition, the formed water droplets are scattered on the outer surface of the carrier storage tank or the surrounding land, and accordingly, there is a problem that the water droplets are frozen in winter to form an ice sheet, thereby becoming an element for environmental safety of the workplace.

In addition, water droplets sprayed on the ground eventually penetrate into the basement, and even though the gas discharged after the filtration process contains some harmful components, the droplets formed by condensation of mist are also harmful components. Soaking into the soil and water is also a problem that is contaminated.

It comprises a gas-liquid separation means for filtering the liquid component contained in the harmful gas.

The gas-liquid separation means includes a guide part for guiding the flow of gas flowing in a wave-shaped panel form in which acid and valley are repeated, and a plate shape protruding from both sides of the guide part and curved in the opposite direction to the gas flow direction. It is composed of a blocking portion for partially blocking the flow of the gas to condense the mist contained in the gas, and includes a corrugated member installed in the reservoir in the form of a plurality of standing at regular intervals.

It includes a particulate member (부재 子 形) is mounted as.

The gas-liquid separation means includes a cooling condensation part that allows the outer wall panel to be made of a metal material having high thermal conductivity, so that the gas introduced into the coolant is cooled in contact with the outer wall panel to condense mist contained in the gas.

The gas-liquid separation means has a ring shape provided on an inner surface of the exhaust communication of the reservoir, and includes a ring-shaped member that partially blocks the flow of the gas rising up through the exhaust communication so that mist contained in the gas is condensed.

The noxious gas filtration device according to the present invention includes a collecting means for collecting and collecting the condensed water produced by the gas-liquid separation means in connection with a space provided with the gas-liquid separation means of the reservoir.

The water collecting means includes a water collecting tank disposed at a lower position than the gas-liquid separating means, a water collecting pipe for transferring the condensed water formed by the gas-liquid separating means in the storage tank, and the condensed water collected in the water collecting tank to the outside.

The noxious gas filtration device according to the present embodiment includes a storage tank in which a carrier is stored, and gas-liquid separation means for filtering the liquid component contained in the noxious gas flowing in the storage tank.

The gas-liquid separating means lowers the flow rate of the harmful gas by inducing the flow of harmful gas into a waveform, and at the same time partially blocks the flow of the harmful gas so that the mist contained in the gas is condensed. A particulate member that causes mist to condense by causing the flow of gas to pass through the interior to be atypical; a cooling condensation unit that allows the mist to condense using a temperature difference; and a gas that flows through exhaust communication. It consists of a ring-shaped member that partially blocks to allow the mist to condense.

As shown in FIG. 1, the corrugated member 20 has a guide part 22 formed in a wavy panel form in which peaks and valleys are repeated, and protrudes from both sides of the guide part 22 to be opposite to the gas flow direction. It consists of a shield 24 in the form of a curved plate.

The blocking part 24 may be provided with a plurality of guide parts at regular intervals, and in this case, the length or the curved angle of each blocking part may be different.

As shown in FIG. 2, the particulate member 30 is preferably formed in a substantially spherical shape having a volume of a predetermined value or less, and a circumferential ring portion 32 that is a morphological reference and connected to each other based on the same. It consists of a plurality of rod-shaped connections 34.

The particulate member 30 is a form in which the flow of gas passing through the inside is atypical, and may be any shape as long as a predetermined number or more is filled in a space of a predetermined volume to satisfy a density of a predetermined value or more.

Meanwhile, as shown in FIG. 3, a plurality of gas-liquid separation spaces are divided into a carrier storage space in the storage tank 10, and each gas-liquid separation means is separately disposed for each type in the gas-liquid separation space. As shown, the corrugated member 20 is installed in a form in which a plurality of them are placed in parallel at regular intervals (see FIG. 5), and the particulate member 30 is installed in a form in which a plurality are filled.

The cooling condensation part 40 is formed in a separate empty space form connected to the gas-liquid separation space in the storage tank 10, the outer wall panel 42 constituting the cooling condensation part 40 is a metal material with high thermal conductivity It consists of.

Exhaust communication 12 for discharging the gas passing through the reservoir 10 is preferably configured in the cooling condensation unit (40).

The order of arrangement of the gas-liquid separation means is preferably such that the corrugated member 20 is first disposed on the basis of the flow direction of the noxious gas, and then the particulate member 30 and finally the cooling condensation unit 40 are disposed. .

In addition, the harmful gas filtering device according to the present embodiment is connected to the space provided with the gas-liquid separation means of the reservoir 10 includes a collecting means for collecting and collecting the condensed water produced by the gas-liquid separation means from the gas .

The water collecting means includes a water collecting tank 60 disposed at a lower position than the gas-liquid separating means, a water collecting pipe 62 transferring condensed water formed by the gas-liquid separating means in the storage tank 10 to the water collecting tank 60, and Discharge pipe for discharging the condensed water collected in the sump (60) to the outside, the inlet is spaced apart by a predetermined height from the bottom surface of the sump (60) is installed higher than the discharge port of the sump (62) ( 64).

Here, the collecting pipe 62 is installed so that the discharge port is downward, the discharge pipe 64 is installed so that the inlet is directed upward, the discharge port of the collecting pipe 62 is close to the bottom surface of the collection tank (60). It is desirable to arrange as low as possible.

Referring to the operation of the noxious gas filtration device according to the present embodiment configured as described above are as follows.

First, the gas passing through the carrier storage space flows into the so-called primary gas-liquid separation space having the corrugated member 20 and flows through the guide part 22 of the corrugated member 20, and the velocity thereof is lowered, and at a predetermined interval. The flow is partially blocked by the blocking portion 24, where the mist contained in the gas condenses and flows down.

The gas that has passed through the primary gas-liquid separation space flows into the so-called secondary gas-liquid separation space with the particulate member 30 and passes at an amorphous state while passing through the particulate member 30 filled in the space. The mist contained in the gas by 30 condenses and flows down.

The gas that has passed through the secondary gas-liquid separation space flows into the cooling condensation part 40, which may be called a third gas-liquid separation space, and the temperature of the gas is relatively high compared to the outdoor air in the season when the temperature of the outdoor air is low, such as winter. Therefore, when the gas comes into contact with the outer wall panel 42, the mist contained in the gas rapidly cools and condenses and flows down.

The gas passing through the cooling condensation part 40 is discharged to the outside through the exhaust communication 12, the gas flowing close to the inner surface of the exhaust communication 12 is blocked by the ring-shaped member 50 to the gas The contained mist condenses again and flows down.

Therefore, according to the present embodiment, the gas containing a large amount of water (mist) while passing through the carrier storage space is separated into the gaseous liquid by sequentially passing through each gas-liquid separation means is converted into a state of much lower moisture content is discharged to the outside The damage caused by the mist can be reduced.

Then, the condensed water produced by each gas-liquid separation means flows down through the water collecting pipe 62 and is collected in the water collecting tank 60, because the inlet of the water discharge pipe 64 is located higher than the discharge port of the water collecting pipe 62. The water collection tank 60 maintains the condensed water level such that the outlet of the water collecting pipe 62 is always locked.

Therefore, even if noxious gas flowing in the storage tank 10 flows to the collecting tank 60 side together with the condensed water through the collecting pipe 62, since the discharge port of the collecting pipe 62 is blocked by the condensed water. Only the condensed water is discharged, and the phenomenon in which no harmful gas is discharged immediately through the collecting pipe 62 is prevented.

On the other hand, according to this embodiment, the noxious gas filtration device can be configured in various combinations and arrangement of each gas-liquid separation means according to the noxious gas treatment capacity or other conditions.

That is, as shown in Figure 6 may be formed in the form that the cooling condensing portion 40 is configured only to place the corrugated member 20 in the primary gas-liquid separation space subsequent to the carrier storage space, and then the secondary gas-liquid separation space. In addition, as shown in FIG. 7, a particulate member 30 may be disposed in the primary gas-liquid separation space instead of the corrugated member 20.

The foregoing descriptions are merely examples of the present invention, and do not limit the scope of the present invention. That is, the biggest feature of the present invention is to constitute a gas-liquid separation means including a corrugated member, a particulate member, or a cooling condensation part, and any modifications should be within the scope of the present invention as long as it satisfies this. This will be more apparent to those skilled in the art through the following claims.

As described above, according to the noxious gas filtration device according to the present invention, since the moisture content of the discharged gas is significantly lowered due to the characteristics of the gas-liquid separation means, the mist contained in the gas is absorbed into the soil by condensation from the outside, and the soil is absorbed. There is an advantage that problems such as contamination can be prevented.
