摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device in which exhaust emission is treated in stages to improve removal efficiency of contaminants without damaging a main filter having active carbon fiber even in an atmosphere in which fire starts. SOLUTION: A body 4 having an inflow port 5 and a discharge port thereof opened is provided with a washing tank 3 for storing washing liquid 10 in the bottom parts thereof. An almost cylindrical frame body 21 where a grid-shaped inner skin shell part 27 is nearly coaxially installed in an almost cylindrical outer skin shell part 25 in which plural vent holes are made is formed. An auxiliary filter 22 formed into nonwoven fabric of metal fiber and a main filter formed into woven fabric of active carbon fiber are held between the outer skin shell part 25 and the inner skin shell part 27. The main filter is arranged on the inner periphery side from the auxiliary filter, protected from flames. A filter body 20 is arranged in the body 4 so that a part thereof is immersed in the washing liquid 10, that the outer peripheral surface thereof airtightly communicates with the inflow port 5, and that it can be freely rotatable by an electric motor 34. Contaminants in an exhaust emission wind flowing through the filter body 20 are separated by turbulent flow of the auxiliary filter 22 while washed with the washing liquid 10 and are adsorbed and separated by the main filter.

摘要： PROBLEM TO BE SOLVED: To provide the device for easily and efficiently removing the component to be separated from gas or liq. with a simple structure. SOLUTION: An inlet 2 and an outlet 3 where a fan 22 is positioned are opened to form an virtually prismatic main body 4. An inner sheath drum 12 is formed within the practically cylindrical outer sheath drum 10 having a wheel 11 on both end faces and with the periphery pierced with a plurality of air holes to form a frame 7. The fine-powder titanium oxide is aggregated and deposited on a woven fabric-shaped filter 8 formed by knitting the activated carbon fiber having /g inner surface area. The filter body 5 formed by attaching the filter 8 to the frame 7 is set in the main body 4 and made rotatable by a motor 16, and a UV irradiator 25 to irradiate the filter 8 with UV is disposed. The contaminant in the air introduced form the inlet 2 by the fan 22 and passed through the filter 8 is immediately adsorbed on the activated-carbon fiber and decomposed by the titanium oxide irradiated with the UV.

摘要： PROBLEM TO BE SOLVED: To efficiently remove an oil and grease content, flue gas particles and an odorous component contained in flue gas and carry out the cleaning treatment for the flue gas. SOLUTION: A flue gas passage from an intake vent 1 to an exhaust vent 2 is formed in a cabinet 3 having the intake vent 1 and the exhaust vent 2, and an oil removing filter 4 for removing the oil and grease, a dust collector 5 for removing flue gas particles, a photocatalyst filter 6 for deoxidizing and a fan 7 forming flows of flue gas are provided on the flue gas passage. The velocity of the flue gas is increased by making smaller a cross-sectional area of the flue gas passage for the oil removing filter 4 to make the flue gas collide with the oil removing filter 4. The velocity of the flue gas is reduced by making larger the cross-sectional area of the flue gas passage for the dust collector 5 to pass the flue gas in the dust collector 5 slowly. The flue gas is diffused by widening the flue gas passage for the photocatalyst filter 6 to increase the chances for the flue gas to be brought into contact with the photocatalyst filter 6.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust purifying device which almost need not a process to clean a contaminated filter by the efficient purification of an exhausted air and requires easy supervisory maintenance services. SOLUTION: An exhaust purifying device main body 15 is arranged in a top lid 8 which has an exhaust duct 14 connected to the upper part and an open lower face. In addition, a grease filter 23 is arranged on the lateral plate part of a main body case 18 with an inflow aperture into which an exhaust air 5 flows. Further, a filter formed, in an endless belt fashion, of stainless steel wires interwoven with cotton, is arranged on rotary shafts 25a, 25b installed, in a freely rotating manner, in the main body case 18. A filter 33 is brought into close contact with the grease filter 23 and an outflow opening part 10 through which the exhaust air 5 flows down, and is soaked partially into a cleaning liquid 40 in a cleaning liquid tank 22 provided on the lower part of the main body case 18. The exhaust air 5 which flows in from the inflow aperture through the grease filter 23 is allowed to flow through the filter 33 moved rotating, and is further allowed into the filter 33 again from a space part 36 to be exhausted after purification. The simultaneous operation to purify the exhaust air 5 and clean the filter 33 is carried out.

摘要： PROBLEM TO BE SOLVED: To efficiently remove the oils and fats, particles of smoke and bad smell components from the exhaust smoke generated by cooking and to discharge a clean air. SOLUTION: A degreasing filter 4 for removing the oils and fats, a dust collector 5 for removing the smoke particles, photocatalytic filters 6 for deodorization and a fan 7 for drawing the exhaust smoke are placed in the cooker main body 1. The exhaust smoke drawn from around the cooking portion collides with the degreasing filter 4 for removal of its oils and fats ingredients and slowly passes through the dust collector 5 for removal of its smoke particles. Then the exhaust smoke is diffused, comes into contact with the photocatalytic filters 6 for removal of its bad smell components and is discharged through exhaust holes 12.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas leaning apparatus capable of highly efficiently removing pollutants contained in an exhaust gas blow and removing malodorous components with a simple constitution. SOLUTION: A first exhaust gas treatment apparatus 17 having a discharge port communicating with an opening of one end of a duct body 13 is installed in a range food 11 in a cooking chamber 5. When the exhaust gas blow 18 flowing through a flow inlet 24 passes through a cylindrical, permeable, and non-combustible filter body 40 rotated by an electric motor, polluting substances are collected. The pollutants are washed out with a washing solution in a washing tank 22 in which the filter body 40 is partially immersed. A second exhaust gas treatment apparatus 19 is installed in the peripheral part of a discharge port 12 of the duct body 13. The malodorous components in the exhaust gas blow from which polluting substances are almost completely removed are brought into contact with a photocatalyst layer on the surface of a ceramic porous body with a three-dimensional mesh structure and bearing ceramic particles on the surface and are decomposed by the photocatalytic function. Even if the exhaust gas blow 18 from a kitchen in extremely polluted state, cleaning treatment can be carried out to a high extent.
