Conventionally, a scrubber device is known as a wet exhaust gas treatment device using water. Conventional scrubber devices include a type of device that sprays water or deodorant liquid onto the exhaust gas, a type of device that sucks up the exhaust gas and water and causes it to flow back like a waterfall, and the exhaust gas is exposed to water and passed through. There is a type of device that creates a spray water layer and allows exhaust gas to pass through the spray water layer and the filter layer alternately. In addition, a method is also adopted in which water is sprayed on rock wool, non-woven fabric, wire mesh, etc., and the exhaust gas is passed through to take in dust and water-soluble gas into the water, but mist-like moisture is discharged into the exhaust gas. It was also unfavorable from the environmental point of view.

In the conventional device as described above, there is a problem that the device is complicated and easily breaks down. In addition, it is necessary to replace the filter in the type of device that uses a filter, and in the conventional device that uses water as described above, individual devices such as a spray and a water pump are required, and maintenance is troublesome.

Therefore, the applicant of the present application has proposed a wet particulate matter treatment apparatus shown in Patent Document 1, which has been well received.

However, in the wet gaseous substance processing apparatus shown in Patent Document 1, in the case of the apparatus in which the intake fan is installed closer to the gaseous substance suction port side than the water storage tank (in the case of the front suction type wet gaseous substance processing apparatus), gas. When an attempt was made to increase the suction force by using an intake fan having a large air volume in order to increase the air volume from the gas suction port, there were the following problems.

In the case of a forward suction type wet gaseous substance treatment device, the sucked gaseous substance collides with the water surface of the water tank on the gaseous substance suction port side with a large wind pressure, so that the amount of gaseous substance containing dirty air is small. There was a problem that it was blown out of the device through a large gap or hole.

Further, in the case of a forward suction type wet gaseous substance processing device, if an intake fan having a large air volume is used, the water surface of the water storage tank on the gaseous substance suction port side is pushed down too much by the large wind pressure, and the gaseous substance is sucked. There is a problem that the gaseous substance including dirty air sucked from the mouth is discharged from the gaseous substance discharge port without much contact with the water in the water storage tank.

It is a schematic explanatory view of the wet particulate matter processing apparatus of FIG. 1, and shows the state of the static water surface. It is a partially enlarged explanatory view of FIG. 3 and shows a state in which a torrent is occurring.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows one embodiment of the wet particulate matter treatment apparatus according to the present invention.

In FIGS. 1 to 4, reference numeral 10 is a wet particulate matter processing apparatus of the present invention.

The wet gaseous substance processing apparatus 10 is formed in the processing chamber 12, the intake fan 14 provided in the upper part of the processing chamber and for sucking the gaseous substance outside the apparatus into the processing chamber 12, and the processing chamber 12. The gaseous substance suction port 16 for sucking the gaseous substance into the processing chamber 12 and the gaseous substance formed in the processing chamber 12 and sucked into the processing chamber 12 are discharged to the outside of the processing chamber 12. The gaseous substance discharge port 18 to be caused, the water storage tank 20 provided in the treatment chamber 12, the gaseous substance sucked from the gaseous substance suction port 16, and the gas discharged from the gaseous substance discharge port 18. A vertical partition plate 22 vertically provided above the static water surface of the water storage tank 20 so as to partition the state substance in the treatment chamber 12, and the water storage tank 20 on the gaseous substance discharge port 18 side. A wavy porous torrent generator 24, which is installed above the static water surface of the water storage tank 20 in parallel with the static water surface of the water storage tank 20 to generate a torrent on the water surface of the water storage tank 20, and a wavy porous torrent generator. At least one porous obstruction plate 26a, 26b, 26c installed above the 24 and for receiving the droplets generated by the torrent, and the vertical partition plate 22 are separated from the vertical partition plate 22 toward the lower end. It has an inclination control plate 28 provided so as to be inclined. Then, the inclination control plate 28 extends downward from the vertical partition plate 22, and the gaseous substance sucked into the treatment chamber 12 comes into contact with the water in the water storage tank 20. It is a wet gaseous substance treatment device that has been made to be purified by.

In the illustrated example, the lower part of the treatment chamber 12 is a water storage tank 20. Since the water storage tank 20 is provided with a water supply / drainage port 30 with a valve, water can be supplied and drained. Further, in the illustrated example, three porous baffle plates 26a, 26b, and 26c are provided as the porous baffle plate. At least one porous baffle plate may be provided, but it is preferable to provide a plurality of porous baffle plates.

Further, as shown in FIG. 3, the porous baffle plates 26a, 26b, and 26c are provided so as to be inclined with respect to the static water surface of the water storage tank 20. In the illustrated example, the water level on the static water surface is the position of T1 as shown in FIG. Further, in the illustrated example, the wavy porous torrent generation plate 24 and the porous obstruction plates 26a, 26b, and 26c are shown as examples made of punching metal.

The wavy porous torrent generation plate 24 is wavy and has a large number of holes. In the illustrated example, the corrugated porous torrent generating plate 24 shows an example in which a punching metal made of SUS is used. For example, a punching metal having a hole diameter of about 3 mm to 5 mm, an aperture ratio of about 50% to 60%, and a wave height of about 10 mm to 20 mm can be preferably used. However, the wavy porous torrent generation plate 24 changes the diameter of the hole, the wave height, or the number of folds (the number of wave periods) depending on the amount of air to be treated, the type and size of dust collected, and the like.

The intake fan 14 is driven by a drive motor 32. Further, although the inclination control plate 28 is provided so as to be inclined with respect to the vertical partition plate 22, it is preferable that the inclination regulation plate 28 is provided so as to be inclined by 15 ° to 40 °. In the illustrated example, as shown in FIG. 4, the inclination angle θ of the inclination control plate 28 is 30 °. The inclination control plate 28 is also supported by the vertical partition plate 22 by the support plate 34.

In FIGS. 1 to 3, the water in the water storage tank 20 shows the state of the static water surface, and the switch of the wet particulate matter treatment device 10 is in the OFF state. FIG. 3 shows the flow of gaseous substances. Since the air outside the wet gaseous substance processing device 10 is sucked into the processing chamber 12 from the gaseous substance suction port 16, the wet gaseous substance is introduced into stores including restaurants, manufacturing factories, chemical factories, plants, and the like. When the processing device 10 is installed, the gaseous substance becomes air containing the gaseous substance.

The processing chamber 12 is formed with a communication suction opening 36 communicating with the gaseous substance suction port 16 and a communication discharge opening 38 communicating with the gaseous substance discharge port 18.

FIG. 3 shows the flow of gaseous substances while the water in the water storage tank 20 in the wet gaseous substance treatment apparatus 10 remains on the static water surface. When the gaseous substance is sucked from the gaseous substance suction port 16 (intake), it is sent to the treatment chamber 12 and comes into contact with the water in the water storage tank 20, and the wavy porous torrent generation plate 24 and the porous obstruction plate 26a , 26b, 26c, and is discharged from the gaseous substance discharge port 18 (exhaust).

The gaseous substance containing dirty air outside the wet gaseous substance treatment device 10 is sucked into the treatment chamber 12 from the gaseous substance suction port 16 and sent to the water tank 20 by the vertical partition plate 22 to discharge water. The water tank 20 has a structure in which air does not leak until it passes through the water tank 20 and is discharged from the gaseous substance discharge port 18.

FIG. 4 shows a schematic view of a state in which the switch of the wet particulate matter processing apparatus 10 is turned on. As shown in FIG. 4, when the switch of the wet gaseous substance processing device 10 is turned on, the gaseous substance is forcibly sucked into the processing chamber 12 from the gaseous substance suction port 16 by the intake fan 14, so that water is stored. The water level of the water on the gaseous substance suction port 16 side in the tank 20 drops to about the water level T2 in FIG.

On the other hand, since the gaseous substance is discharged from the gaseous substance discharge port 18, the water level of the water W of the gaseous substance discharge port 18 in the water tank 20 is raised, and the water level in contact with the wavy porous torrent generation plate 24. It becomes T3.

Further, since the inclination control plate 28 extends downward from the vertical partition plate 22, a vortex 40 of a gaseous substance is formed on the back side of the inclination regulation plate 28. Then, the water W in the water storage tank 20 collides with the gaseous substance, collides with the holes of the wavy porous torrent generation plate 24, becomes a violent torrent trying to escape, and blows from the entire surface of the wavy porous torrent generation plate 24. Go up. At this time, bubbles and droplets are also generated. In this way, all of the gaseous substances including the inhaled dirty air are brought into contact with the water stream.

Therefore, the wet gaseous substance processing apparatus 10 of the present invention is an apparatus (front suction type wet gaseous substance processing apparatus) in which the intake fan is installed closer to the gaseous substance suction port side than the water storage tank, but the intake fan 14 Even if a fan of the type that has a large air volume and exerts a strong force to suck in the outside air is used, all the gaseous substances including the intake dirty air come into contact with the water flow and are purified. Therefore, as in the conventional case, there is a problem that the gaseous substance containing dirty air is blown out of the device through a slight gap or hole, and the gaseous substance containing dirty air sucked from the gaseous substance suction port. The problem that the substance is discharged from the gaseous substance discharge port without being in much contact with the water in the water tank does not occur. Further, by providing the inclination control plate 28, there is an advantage that the amount of water W in the water storage tank 20 can be reduced as compared with the conventional case.

The generated torrent causes droplets to be generated, but the water droplets 42 are repelled by the porous baffle plates 26a, 26b, 26c installed above the water surface and returned to the water storage tank 20.

In this way, the gaseous substance is purified by coming into contact with the water W of the water tank 20. Large particles such as black smoke, oil smoke, and paint are removed by water W. Then, the gaseous substance is discharged from the gaseous substance discharge port 16.

Further, a deodorizing device may be attached to the gaseous substance discharge port 16, and for example, a deodorizing device using a heater as shown in Patent Document 1 may be attached.

According to the wet gaseous substance treatment apparatus of the present invention, carbon-based ultrafine particles generated from combustion of kerosene, heavy oil, etc. can be efficiently separated and recovered, and dust can be removed.

Further, as shown in Patent Document 1, the wet gaseous substance treatment device of the present invention may be equipped with a circulation filtration device configured to circulate the water in the water storage tank to the circulating water tank by a circulation pump.

When installing in the kitchen of a store such as a restaurant, use a smaller size of the wet gaseous substance processing device of the present invention, and when installing in a manufacturing factory, chemical factory, or plant, wet gas. It is sufficient to use a larger size of the state substance processing apparatus. When installed in a store such as a restaurant, it is possible to effectively separate and remove flue gas and the like generated by cooking. Further, if the size of the wet particulate matter processing apparatus is reduced, it can be placed on a tabletop and used as a tabletop in a restaurant, a factory or a facility. As described above, the wet gaseous substance treatment apparatus of the present invention can perform purification treatment by installing it in various places where flue gas and exhaust gas are generated.
