DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example will be described with reference to FIG. A is an oil separator in a kitchen or the like of the present invention. The separator body 1 has a cylindrical shape at the upper part and a conical shape at the lower part.
Reference numeral 2 denotes an inlet for contaminated gas containing oil, and 3 denotes a partition plate hanging down from the top wall of the separator, and a lower portion 3a is curved in an arc shape.
As a result, the partition plate 3 partitions the cylindrical portion into an inlet chamber 5 and an outlet chamber 6. A horizontal scattering prevention plate 4 is fixedly provided at the center of the partition plate 3. The tip 4a of the scattering prevention plate 4 is also curved in a downward arc shape. Reference numeral 7 denotes a stirring plate, and the lower portion 7a is similarly curved in an arc shape. The curved portions of the partition plate 3 and the stirring plate 7 face each other.

An exhaust fan 8 is provided above the outlet chamber 6. The lower part of the main body forms a stirring chamber 18 for storing water, and a drain pipe 9 is connected to the lower end thereof. A pipe 10 provided with a filter 11 and a pump 12 is connected to the lower end of the stirring chamber 18, and the other end of the pipe 10 is provided with a shower provided on the side of the inlet chamber.
It leads to the nozzle 13. Reference numeral 14 denotes a water supply pipe, which communicates with a lower portion of the inlet chamber via a valve. Reference numeral 15 denotes an oil separation chamber, in which an oil-water mixture discharged from a discharge pipe 16 provided below the outlet chamber 6 accumulates. In the above apparatus, a perforated plate (not shown) may be provided in front of the exhaust fan 8 instead of the scattering prevention plate 4.

(Operation) When the gas is blown from the inlet 2 of the contaminated gas, the gas traverses the water film blown from the shower nozzle 13 in the vertical direction, collides with the upper surface of the water stored in the stirring chamber 18, and furthermore, the partition plate 3 flows leftward along the lower curved portion 3a, and reverses and rises at the lower curved portion 7a of the stirring plate 7. The upward flow contains mist, collides with the scattering prevention plate 4, and flows downward this time at the tip curved portion 4a. During this time, the oil in the contaminated gas falls into the water in the stirring chamber 18 together with the mist. The clean air is exhausted through an exhaust fan 8.

The oil floating on the upper portion of the stirring chamber falls through the discharge pipe 16 into the oil separation chamber 15, where it is further separated by a specific gravity difference, and the floating waste oil flows out of the discharge pipe 17.
On the other hand, the water in the stirring chamber 18 is purified by the filter 11 by the pump 12 and circulated and supplied to the shower nozzle 13. The water in the stirring chamber is appropriately supplied with a water supply pipe 14.

Thus, the pollutant gas is purified and discharged. At this time, since the gas once passes through the water, the fire is completely extinguished, and a damper for fire prevention is not required. Similarly, the hot air is cooled by water and does not adversely affect the apparatus or the duct. If a deodorant is injected into the water, a comfortable kitchen environment can be created.

(Embodiment 2) FIG. 2 shows a roast roaster. In the lower part of the opening 21 of the table 20, a grill 2 is provided.
2 is provided, and the meat is roasted on the burner 23. At this time, a pollutant gas containing a large amount of oil is generated.

In the lower part of the opening 21, an inlet chamber 24 having a truncated conical shape, which is narrowed downward with a grill 22 therebetween, is formed. The lower part of the inlet chamber 24 becomes a cylindrical part 25, and the stirring chamber 26
It is continuous.

A cylindrical plate 25 communicating with the stirring chamber 26 is provided with a partition plate 3 having a lower curved portion 3a as in the embodiment of FIG. A stirring plate 7 having a curved lower portion 7a facing the partition plate 3 and also facing the lower curved portion 3a is provided. The flow once directed upward by the partition plate 3 and the stirring plate 7 is diverted downward again by the scattering prevention plate 4, is discharged as purified air through the exhaust fan 8, and is discharged outside.

As in the case of FIG. 1, water in the stirring chamber 26 is sucked by the pump 12 through the filter 11 and blown out from the shower nozzle 13 into the lower part of the conical inlet chamber 24 to form a water film.

(Operation) When the contaminated air containing oil by the roasted meat flows downward through the water spray film from the shower nozzle 13, the hot air is cooled and the oil is mixed with water to enter the stirring chamber 26. Fall. Due to the suction force of the exhaust fan 8, the partition plate 3, the curved portions 3 a of the stirring plate 7, and the anti-scattering plate 4 violently collide with the water surface of the stirring chamber 26 while zigzag, and are purified and discharged.

Thus, according to the present embodiment, since the water film continuously jetted by the spray nozzle extends over the entire area of the exhaust passage, the hot air is thereby cooled and the fire prevention measures are thorough. Also, if you put a detergent to emulsify oils and fats in water,
Oil separation can be performed more effectively. Yakiniku is very dirty with animal oils, but has a powerful spray.
The inside of the duct is also cleaned at the same time by the water film by the nozzle. Since the hot exhaust air is quickly sucked downward, the tilt caused by the hot air can be eliminated. Since the water is completely removed by the centrifugal fan, there is no risk of water leakage or the like occurring halfway through the connecting duct.

(Embodiment 3) FIG. 3 shows another example of the grilled meat roaster shown in FIG. The oil-containing gas generated by the grill 22 is formed to be thin downward with a water film formed by a shower nozzle 28 tangentially ejected from the side wall of the cylindrical outer shell 27 to the inner wall of the outer shell. It descends while turning toward the cyclone inner pipe 29. Shower nozzle 2
8 is provided tangentially to the cylindrical outer shell 27, so that the shower blown out from this turns along the inner wall of the outer shell 27 and descends along the inner wall of the cyclone inner pipe 29. However, at this time, the centrifugal force causes oil (emulsified) in the gas and contaminants to fall into the liquid in the lower stirring chamber 31 along the inner wall of the cyclone.

The cyclone inner pipe 29 is provided with a plurality of communication holes 35 around it, and the dust basket 30 connected to the lower part of the cyclone inner pipe 29 is filled with water. The floated oil flows out of this hole into the outer shell, and is discharged by the overflow tube 32. 3
Reference numeral 3 denotes an exhaust fan, which discharges air accumulated in the upper part of the stirring chamber 31.

The overflow tube 32 has a check valve 34 which is closed during operation. There are a plurality of communication holes 35 in the lower part of the cyclone inner pipe 29, and oil on the dust basket 30 flows out of the pipe.
a, 36b. Although not shown, it is preferable to attach a filter / net under the shower nozzle to separate large pieces such as meat pieces falling from above. Stir chamber 31
Water is supplied from the opening 21 of the table, and the water level before the operation is up to the level of the overflow pipe 32.

(Embodiment 4) A description will be given based on FIG.
In FIG. 4, reference numeral 37 denotes an agitating chamber for storing water. An underwater shower nozzle 38 is provided at the bottom of the agitating chamber, and the shower is blown up from this to a shower chamber 39 above.

Steam / oil smoke or polluted air (hereinafter referred to as polluted gas) is blown by an exhaust fan 44 in a duct 45, flows upward through the duct 40, and enters a stirring chamber 37 in which water is stored. The direction is changed downward from the inner upper edge 41, and the water is introduced into the water along the lower edge curved portion 42a of the partition 42 on the entrance side of the shower chamber 39 partitioned by the pair of partitions 42 and 43. Stirring chamber 3 at entry pressure
The oil smoke and the like that entered by pushing down the water surface of No. 7 were further showered.
It mixes with the shower blown up in the chamber 39 and collides,
Washed. The clean gas that has left the stirring chamber 37 is discharged outside through a duct 45. Reference numeral 45a denotes a branch duct for returning the cleaned air to the room as required.

Reference numeral 46 denotes an operation panel, which controls the exhaust fan 44, the underwater shower nozzle 38, the solenoid valve 47, and the like. Reference numeral 48 denotes a water supply pipe provided with a solenoid valve 47 and a check valve 49 for adjusting the amount of water in the stirring chamber 37. 50 is a drain valve, 5
Reference numeral 1 denotes an overflow tube of the stirring chamber 37.

(Operation) The operation of the operation panel 46 causes the exhaust fan 4
When the dial 4 is turned, the underwater shower nozzle 38 is also driven, so that oil smoke or the like is blown from the duct 40 and enters the water in the stirring chamber 37. At the same time, the shower by the underwater shower nozzle 38
And the mixture is purified by repeating mixing and collision, and discharged again through the water into the duct 45.

Water is supplied by opening and closing a solenoid valve 47, and when water is supplied, oil separated and floated on the water surface is discharged through an overflow pipe 51.

Foreign matter collected at the bottom of the stirring chamber 37 is discharged by opening the drain valve 50. The check valve 49 prevents the backflow of the contaminated water to the water supply side.

Thus, the oily smoke and the like collide with the water in the stirring chamber 37 and collide with the upward shower in the shower chamber 39, and are further purified and discharged through the water in the stirring chamber 37. Its purification is extremely high.

[0029]

According to the first aspect of the present invention, the contaminated gas takes on water droplets when passing through the water film ejected from the shower nozzle, and collides with water in the stirring chamber. Due to the stirring effect at the time of collision, the direction of the partition plate 3 and the lower end of the stirring plate 7 can be changed together with the water. As described above, the separation action is extremely effectively performed due to the large number of opportunities for contact with water and the large number of opportunities for collision. Further, since the oil containing water droplets completely falls on the water surface due to the presence of the scattering prevention plate 4, only the purified gas is discharged by the exhaust fan 8.

According to the second aspect of the present invention, the gas generated from the roasted meat table also takes on water droplets from the water film from the shower nozzle.
The oil is completely dropped into the water by the partition plate, the stirring plate, and the splash prevention plate, and only the purified gas is discharged to the outside.

According to the third aspect of the present invention, the oil component that has been water-dropped by the water film is separated by the centrifugal action of the cyclone and falls into the water in the stirring chamber. Although it has a very simple structure, it can also efficiently separate contaminated air generated from the roasted meat table.

According to the fourth aspect of the present invention, the contaminated gas first collides with water, then passes through a water film formed by a shower jetted from an underwater shower nozzle at the bottom of the stirring chamber, and further enters water in the stirring chamber. Is discharged. In particular, oil combined with water droplets in the shower chamber above the stirring chamber falls into water and is separated. As described above, the separation action is extremely effectively performed due to the large number of opportunities for contact with water and the large number of opportunities for collision. Thus, only the purified gas is exhausted by the exhaust fan.
