摘要： PURPOSE:To improve the capturing efficiency for carbon in waste gases by integrating solid fibrous ceramics to three-diamensional structure thereby increasing surface areas and complicating gas flow passages. CONSTITUTION:After fine powder of ceramics (cordierite), a binder (methyl cellulose) and water are kneaded, the mixture is extruded by an extrusion molder to form fibrous ceramics 1 having about 1mm. diametral size and before drying these ceramics, a three-dimensional structural material A having intricately entangled flow passage parts is constituted. Said material is constituted by putting the extruded fibrous ceramics directly into a circular columnar vessel. After the material A is thoroughly dried in a dryer, the material is calcined in an electric furnace, whereby the three-dimensional structural body of the fibrous ceramics is obtained.

摘要： PURPOSE:To both improve heating efficiency of a device and increase its compactness and assembly workability or the like, by arranging the captioned device in an exhaust gas passage and providing an electric heater of specific construction in the upstream side of a heat resistant filter member in said device. CONSTITUTION:A fine grain purifier 4, interposed in the downstream of an exhaust manifold in an internal combustion engine, is constituted by housing a filter member 42, consisting of porous ceramic material, in a vessel 41 through a shock absorbing member 44 and sealing member 45, and jointing an electric heater 43 to an end side in the upstream side of said filter member. At this time, the electric heater 43 is formed to annular shape with a heating unit 43b to one side of an electric insulator base plate 43a by the method of evaporation or printing, and conductors 43c are connected to the both ends of the heating unit and similarly formed to electrically conduct said unit. Then an electric insulator 43b is formed to film shape by printing fully over the base plate 43a so as to coat these heating unit 43b and conductors 43c, to constitute the purifier.

摘要： PURPOSE:To provide such projections which disturb the flow of exhaust gases uniformly by a simple method by providing many projections by foaming the surfaces of skeleton made of ceramics. CONSTITUTION:Many projections 3a are provided on the surfaces of skeleton 4 of a ceramic porous body or ceramic honeycomb structural body which is a structure for purification of exhaust gases from internal combustion engines of automobiles or the like, by causing metallic powder of aluminum, iron or the like and acid to react thereby producing gaseous hydrogen and forming said surfaces. The structure obtained in this way disturbs the flow of the exhaust gases by the projection 3a and captures fine particles of carbons with good efficiency.

摘要： PURPOSE:To minimize leak of gas from a cleaning device for fine particle contained in exhaust gas, by providing an exhaust-gas-fine-particle-capturing unit member with an outside covering made of a material having a larger ventilation resistance, and also by providing an annular seal between the outside covering and a casing. CONSTITUTION:Exhaust gas containing fine particles goes from an intake 17 of a cleaning device into a fine-particle-capturing material 10 made of ceramic. While the gas in the fine-particle-capturing material 10 is trying to leak out from the outside circumference, since it is enclosed by the material having a larger ventilation resistance, it is not allowed to leak out from the outside circumferencial area in any case. And, although the gas at the intake 17 is trying to leak out through a gap between the fine-particle-capturing material 10 and a casing 12, as an annular elastic seal 28 is pressed into the gap, the gas is prevented from leaking out. Thus cleaned exhaust gas is then discharged from an exit 19 to outside.

摘要： PURPOSE:To enable to effectively trap fine particles contained in exhaust gases by providing a plurality of projections on a skeleton of a porous ceramic body which skelton provides inside continuous spaces for passage of exhaust gases. CONSTITUTION:The structure A for cleaning the exhaust gases of an internal- combustion engine of an automobile or the like consists of the porous ceramic body 1 of a three-dimensional network structure having the inside continuous spaces 2 communicated with the exterior. The skeleton 3 comprising the spaces 2 is covered by a ceramic layer 4 having a plurality of the projections 4a. To produce the structure A, for example, a cylindrical foamed body of an organic material (polyurethane or the like) of a three-dimensional network structure having inside continuous spaces communicated with the exterior is applied with a predetermined amount of a slurry of cordierite powders containing a binder by repeating an infiltration-drying cycle. Then, a urethane-based slurry of cordierite powders and other slurry are infiltrated into the inside spaces and are foamed on the surfaces of the skeleton of the cylindrical foamed body, followed by drying and sintering to obtain the structure A.

摘要： PURPOSE:To enhance the efficiency in cleaning exhaust gases by providing a plurality of projections on the inside walls of through-holes for passing exhaust gases in honeycomb structure. CONSTITUTION:The ceramic honeycomb structure 1 consisting mainly of cordierite and used for cleaning the exhaust gases emitted from an internal-combustion engine of an automobile or the like has a plurality of through-holes 2. The inside walls of the through-holes 2 are provided with a ceramic layer 3 having a plurality of the projections 3a arranged irregularly thereon. To produce the structure, pellets of a combustible organic material such as a resin or carbon are packed into the through-holes 2 of the honeycomb structure 1, and then a slurry of a mixture containing a cordierite powder, methyl cellulose and water is poured into the gaps left after the packing. Further, air in the through-holes 2 is completely evacuated by a vacuum pump or the like, followed by drying and sintering, whereby the organic material is burned away to obtain the structure A provided with the projections 3a.

摘要： PURPOSE: To miniaturize an exhaust gas purifier and to make the latter light weight, by providing only one hot-air supply means and by eliminating an additional hot-air passage so as to lessen the number of necessary parts.
CONSTITUTION: Exhaust gas which is discharged through a pipe 2 from a diesel engine or the like and is introduced through a flow passage diversing valve 9 into one of filters 81, 82 that are arranged in parallel, is purified and then discharged to the atmosphere through a pipe 7. A portion 105 in opposite to an exhaust gas inlet portion 6 through the diversing valve 9 is supplied with hot air for reforming the filters 81, 82 through a pipe 10. ASccordingly, the hot air is introduced into one of filters 81, 82 which is out of operation, for burning fine particles in the filter to reform the filter. Since the hot air supplying port 105 is arranged in a position in opposite to the exhaust gas intake portion 6, the purifier device can have a simple structure in which stagnation is exhaust gas is minimized.

摘要： PURPOSE: To reduce the amount of discharge of unburned hydrocarbon at the time of ignition and extinction of fire through a comparatively small-sized device by a method wherein a fuel is vaporized after it is mixed with heated combustion air.
CONSTITUTION: Air supplied from a combustion air supply device comprising a pump or the like flows into the liquid fuel combustion apparatus from an air inlet of the latter. Then, the air passes through an electrical heater block 2 to be heated up to a temperature between about 200 and 300°C and flows into a mixing chamber 4 via a communication hole 3. On the other hand the fuel supplied from a liquid fuel supply device flows into the combustion apparatus through a pipe 5 and is injected into the mixing chamber 4 through a nozzle 5a. As a result, the fuel is subjected to a high speed stream of the heated combustion air so that the amount of discharge of the unburned hydrocarbon at the time of ignition and extinction of fire can be reduced.
