The present invention relates to a device for removing malodor using a microbial carrier, and more particularly, to improve the malodor removal efficiency by performing a pretreatment using a wet multi-rotating plate before the malodor gas is introduced into the microbial carrier. The present invention relates to a microbial carrier odor removal device using a wet multi-turn plate pretreatment.

Waste gas treatment by biological methods such as biofilters using microorganisms is a method of safely decomposing and treating odorous substances and harmful volatile substances in waste gas in aerobic state by using microbial metabolism process, and is an economical and environmentally friendly waste gas treatment method. It is attracting attention by the method.

However, the conventional method for treating waste gas by microorganisms is to pass waste gas into the tank when water is supplied to the waste gas, or to spray water on the upper side of the waste gas, so that sufficient amount of the waste gas can be adsorbed. There is a problem that moisture is not supplied and waste gas is not reduced to a microbial reaction temperature at an appropriate temperature.

Another odor and volatile organic material removal device proposed to solve this problem is to install a humidifier in the middle of the waste gas inlet, a path through which waste gas flows into the microbial reaction part, but the configuration of the humidifier and the humidifier tank A rotational shaft installed in the center in the center perpendicular to the inflow direction of the waste gas; It characterized in that it comprises a drive belt for transmitting the rotational force of the rotational force of the drive motor.

The waste gas passing through the humidifying unit configured as described above heat exchanges the waste gas in a high temperature state by the water film formed on the surface of the plurality of rotating disks in which the waste gas is installed in parallel with the traveling direction in the humidifying unit to lower the temperature of the waste gas. . In addition, the fine dust particles contained in the waste gas is attached to the water film formed on the surface of the rotating disc to remove various foreign substances contained in the waste gas.

However, the humidifying part according to the prior art has a large size of the rotating disc and is mounted at a close interval on one shaft. Therefore, when the rotating disc is driven continuously for a long time, the bending of the shaft is generated by the weight of the rotating disc. If the shaft is bent in this way, the gap between the rotating discs is not kept constant and the one side is caused to be inclined so that the flow of waste gas is not smooth. In addition, there is a problem in that the shape of the rotating disk is deformed by the phenomenon that friction between the rotating disks due to the rotation of the rotating disk or interference with each other. In addition, the humidifying part according to the related art has a water film formed on the surface of the rotating disk in a state in which the rotating disks are always submerged in water, so that the load of the rotating disk applied to the shaft is increased.

In addition, conventionally, the water film is formed on the surface of the rotating disc only by contact with water accumulated on the bottom of the humidifier, and since the size of the rotating disc is extra large, the surface of the rotating disc is moved by gravity toward the top while rotating the rotating disc. There is a problem that the thickness of the water film formed in the film becomes thin.

Therefore, when the thickness of the water film formed on the surface of the rotating disk becomes thinner, the water film formed on the surface of the rotating disk lowers the temperature of the waste gas passing between the rotating disk and the rotating disk or removes foreign substances contained in the waste gas. There is a problem that can not be done.

The lower end of the upper disk 222 and the upper end of the lower disk 232 are formed to have a diameter that can be rotated while the edges overlap each other. Therefore, the upper disk 222 and the lower disk 232 installed in the upper and lower two stages in the internal space of the humidifying tank 210 can be significantly reduced in the size of the diameter of each disk compared to the conventional rotating disk have. However, since the upper and lower disks 222 and 232 are alternately installed to have areas overlapping each other, the processing capacity of the waste gas passing through can be maintained or rather increased as before.

Referring to FIG. 3, a plurality of disks 222 and 232 mounted in a row on the upper and lower shafts 221 and 231 are fixed to collars 223 and 233 on the outer circumferential surface of the shaft. do. In this case, the disks are firmly fixed on the outer circumferential surface of the shaft individually by the collar to prevent the shaft from bending or the disk from twisting on the shaft.

In addition, referring to Figure 4, the upper and lower shafts 221, 231 may be provided with support means for supporting the shaft in a substantially intermediate portion. Such support means may use supports including oilless casings 224 and 234. Therefore, when the device extends the lengths of the upper and lower shafts 221 and 231 according to the construction conditions, the supporting means is disposed at two or more appropriate positions in the middle of the shaft.

The driving means 250 for driving the upper and lower bio-disc drum assemblies 220 and 230 is mounted on the motor 251 and the rotating shaft of the motor 251 and mounted on one end of the lower shaft 231. A driving gear 252 and an interlocking gear 253 which is installed at one end of the upper shaft 221 while meshing with the driving gear 252 to rotate the upper shaft 221 by the rotation of the driving gear 252. do.

The operation of the microorganism carrier odor removal device using the wet multi-turn plate pretreatment according to the present invention configured as described above will be described.

When the waste gas discharged from the facility is introduced through the waste gas inlet unit 100, the introduced waste gas passes through the humidifying unit 200 in a state before being supplied to the microbial reaction unit 300 having the microbial carrier.

The waste gas is fine between the upper and lower disks 222 and lower disks 232 by upper and lower shafts 221 and 231 which are rotated by the driving force of the motor 251 when the humidifying part 200 passes. Pass through the gap. That is, the rotational force of the motor 251 is transmitted to the drive gear 252 so that the lower shaft 231 is rotated by the rotation of the drive gear 252, and the interlocking gear 253 meshed with the drive gear 252 simultaneously. While rotating, the upper shaft 221 is rotated by the rotation of the interlocking gear 253.

At this time, as shown in Figure 5, the upper disk 222 is rotated in the reverse direction with respect to the direction in which the lower disk 232 is rotated. For example, when the lower disk 232 is rotated clockwise, the upper disk 222 is rotated counterclockwise. As described above, the upper and lower disks 222 and 232 rotate in opposite directions while being rotated while overlapping the lower end of the upper disk 222 and the upper end of the lower disk 232 in a staggered state. Therefore, the vertical gap between the upper disk 222 and the lower disk 232 is not generated so that the waste gas passing through the humidification tank 210 can be processed by both the upper and lower disks (222, 232).

The upper disk 222 is formed with a water film on the surface by the water sprayed from the spray nozzle 240 installed on the interior ceiling of the humidifier 210, the lower disk 232 is humidified through the water supply line 261. As the lower disk 232 is rotated by the water supplied into the tank 210, a water film is formed on the surface of the lower disk 232.

In the state where the water film is formed on the surfaces of the upper disk 222 and the lower disk 232, the waste gas passes through the gap between the upper disk 222 and the gap between the lower disk 232. Heat exchange causes the temperature to drop to a temperature suitable for reaction with the microorganisms. At this time, the temperature of the water is measured in real time by the temperature sensor 271, when the temperature falls below the set temperature, the heater 272 is automatically operated by the temperature controller 273 to raise the water temperature to the set temperature.

In addition, the fine particles of the foreign matter contained in the waste gas is attached to the water film of the upper and lower disks 222 and 232 and removed. Alternatively, as the water sprayed from the spray nozzle 240 descends, foreign substances contained in the waste gas are removed. The foreign matter removed from the waste gas is discharged to the outside of the humidification tank 210 in the process of circulating water through the water discharge line 263 together with the water stored in the inner bottom of the humidification tank 210.

Referring to FIG. 5, the waste gas introduced into the turbulent state is converted into a laminar flow while the gas flows through the gap between the upper and lower disks 222 and 232. Therefore, the waste gas in the laminar flow state supplied through the humidifying unit 200 to the microbial reaction unit 300 passes through the microbial reaction unit 300, and the efficiency of removing odors when reacting with microorganisms is remarkably improved.

The waste gas supplied to the microbial reaction unit 300 passes through the carriers provided in the shelf installed in multiple stages while descending from the top to the lower end in the microbial reaction unit 300, and various odorous substances contained in the waste gas while passing through the carrier. And volatile organic substances (VOCs) are oxidized with microorganisms and finally converted into carbon dioxide and water and discharged.

In addition, the microbial reaction unit 300 is supplied with nutrients from the nutrient tank 400, the microorganisms attached to the carrier is supplied with the inorganic nutrients necessary for growth, the neutralizing agent tank 500 from the neutralizer or circulating water PH Neutral supply is made so that the growth of microorganisms is made smoothly.

In the above-described embodiment, the case in which the bio-disc drum assembly is installed in two stages is described. However, the embodiment in which the bio-disc drum assembly is installed in three or more stages in the vertical direction is also possible. In the case where the drum assembly is installed in two or more stages in the left and right directions, it may be installed according to the construction conditions, and these embodiments will all be said to belong to the scope of the technical idea of the present invention.
