Definitions
- the present invention relates to a honeycomb filter and a ceramic filter assembly, and more particularly, to a honeycomb filter made of a ceramic sintered body and a ceramic filter assembly integrated by bonding a plurality of honeycomb filters.
- a general exhaust gas purification device has a casing provided on the way of an exhaust pipe connected to an exhaust manifold of an engine, and a filter disposed therein and having fine holes.
- Materials for forming filters include ceramics in addition to metals and alloys.
- a honeycomb filter manufactured by Kodielite is known.
- porous silicon carbide sintered bodies that have advantages such as heat resistance, mechanical strength, high collection efficiency, chemical stability, and low pressure loss have been used as filter forming materials. There are many.
- pressure loss means the pressure value on the upstream side of the filter minus the pressure value on the downstream side. Means something. Exhaust gas undergoes resistance as it passes through the filter and is the largest contributor to pressure loss.
- the honeycomb filter has a number of cells extending along its own axial direction. As the exhaust gas passes through the filter, particulates are trapped by the cell walls. As a result, fine particles are removed from the exhaust gas.
- honeycomb filters made of porous silicon carbide sintered bodies are vulnerable to thermal shock. Therefore, cracks tend to occur in the filter as the size increases. Therefore, as a means of avoiding damage due to cracks, a technique of manufacturing a single large ceramic filter aggregate by integrating a plurality of small filter pieces has been proposed in recent years.
- a rectangular pillar-shaped honeycomb formed body is formed by continuously extruding a ceramic raw material using a mold of an extruder. After cutting the honeycomb formed body into equal lengths, the cut pieces are fired to form a filter. After the sintering process, a plurality of filters are bundled and integrated by bonding the outer peripheral surfaces of the respective filters via a ceramic sealing material layer having a thickness of 4 to 5 mm. As a result, a desired ceramic filter assembly is completed.
- a mat-like heat insulating material made of ceramic fiber or the like is wound around the outer peripheral surface of the ceramic filter assembly. In this state, the assembly is housed in a casing provided on the exhaust pipe.
- honeycomb filter of the related art since the honeycomb filter of the related art has a square shape as a whole, stress tends to concentrate on a corner portion of the outer peripheral surface, and chipping may occur there. In addition, cracks may occur on the sealing material layer side starting from the corners, which may cause the ceramic filter assembly to break. In addition, even if the assembly does not break down, the processing efficiency is reduced by exhaust gas leakage. There was a problem that the rate declined.
- the conventional ceramic filter assembly has a rectangular cross section as a whole, and by cutting the outer shape of such an assembly, it can be formed into a substantially circular cross section or a substantially elliptical cross section as a whole. Has also been done.
- the filter has a large number of cells, when the outer shape of the assembly is cut, the cell walls are exposed on the outer peripheral surface of the aggregate after the cut, resulting in unevenness on the outer peripheral surface. . Therefore, even if the assembly is housed in the casing together with the heat insulating material provided on the outer peripheral surface, a gap is formed along the longitudinal direction of the filter. For this reason, there is a problem that the exhaust gas leaks through the gap and the processing efficiency of the exhaust gas decreases.
- particulates collected by honeycomb filters it has been found that particulates with a small particle size have a high lung retention rate and a high health risk. Therefore, the demand for supplementing particulates with small particle size is increasing.
- the honeycomb filter becomes too dense, and it becomes difficult for the exhaust gas to pass through the honeycomb filter smoothly, and the pressure loss increases. If the specific surface area of the particles constituting the cell wall is too small, the honeycomb filter becomes too dense, and it becomes difficult for the exhaust gas to pass through the honeycomb filter smoothly, resulting in a large pressure loss. Therefore, there is a problem in that the driving conditions of the vehicle are hindered, fuel consumption is deteriorated, and driving feeling is deteriorated. Conversely, if the pore diameter and porosity are large, the above-mentioned problems can be solved. However, since the air gap in the honeycomb filter becomes too large, fine particles are collected. P

- the exhaust gas purification device 1 is a diesel engine as an internal combustion engine. This is a device for purifying exhaust gas discharged from the engine 2.
- the diesel engine 2 includes a plurality of cylinders (not shown). Each cylinder is connected to a branch 4 of an exhaust manifold 3 made of a metal material. Each branch 4 is connected to one manifold body 5. Therefore, the exhaust gas discharged from each cylinder is concentrated at one place.
- a first exhaust pipe 6 and a second exhaust pipe 7 made of a metal material are provided downstream of the exhaust manifold 3.
- the upstream end of the first exhaust pipe 6 is connected to the manifold body 5.
- a cylindrical casing 8 made of a metal material is provided between the first exhaust pipe 6 and the second exhaust pipe 7, a cylindrical casing 8 made of a metal material is provided.
- An upstream end of the casing 8 is connected to a downstream end of the first exhaust pipe 6, and a downstream end of the casing 8 is connected to an upstream end of the second exhaust pipe 7.
- the center of the casing 8 has a larger diameter than the exhaust pipes 6 and 7. Therefore, the internal area of the casing 8 is wider than the internal areas of the exhaust pipes 6 and 7.
- the casing 8 accommodates a ceramic filter assembly 9.
- a heat insulating material 10 is provided between the outer peripheral surface of the assembly 9 and the inner peripheral surface of the casing 8.
- the heat insulating material 10 is a mat-like material containing ceramic fibers, and has a thickness of several mm to several tens of mm.
- the heat insulating material 10 preferably has a thermal expansion property.
- thermal expansion means that it has a function of releasing thermal stress due to its elastic structure. The reason is that by preventing heat from escaping from the outermost peripheral portion of the assembly 9, energy loss during regeneration is minimized. Further, by expanding the ceramic fiber by the heat at the time of regeneration, it is possible to prevent the displacement of the ceramic filter assembly 9 caused by the pressure of the exhaust gas, vibration due to running, and the like.
- the ceramic filter assembly 9 removes diesel particulates and is generally called a diesel particulate filter (DPF). .
- the aggregate 9 is formed by bundling and unifying a plurality of filters F1.
- a rectangular column-shaped filter F1 is arranged at the center of the assembly 9, and its outer dimensions are 33 mm x 33 mm x 167 mm (see Fig. 3).
- a plurality of non-rectangular column-shaped filters F1 are arranged.
- a columnar ceramic filter assembly 9 (diameter of about 135 mm) is formed as a whole.
- These filters F1 are made of a porous silicon carbide sintered body which is a kind of a ceramic sintered body.
- the reason why the silicon carbide sintered body was adopted is that it has an advantage of being particularly superior in heat resistance and thermal conductivity as compared with other ceramics.
- a sintered body other than silicon carbide for example, a sintered body such as silicon nitride, sialon, alumina, cordierite, and mullite can be selected.
- each filter F1 is so-called honeycomb structures.
- the reason for using a honeycomb structure is that there is an advantage that pressure loss is small even when the amount of collected fine particles increases.
- a plurality of through holes 12 having a substantially square cross section are formed regularly along the axial direction.
- Each through hole 12 is separated from each other by a thin cell wall 13.
- an oxidation catalyst composed of a platinum group element (for example, Pt or the like), another metal element, and an oxide thereof is supported.
- the opening of each through hole 12 is sealed by a sealing body 14 (here, a porous silicon carbide sintered body) on one of the end faces 9a and 9b.
- the entire end faces 9a and 9b have a checkered pattern.
- a large number of cells having a square cross section are formed in the filter F1.
- the cell density is set to about 200 cells / inch
- the thickness of the cell wall 13 is set to about 0.3 mm
- the cell pitch is set to about 1.8.
- about half are open at the upstream end face 9a, and the rest are open at the downstream end face 9b.
- Finoleta F 1 has an average pore diameter of 1 ⁇ m to 50 m, and even 5 ⁇ ! It is preferably about 20 ⁇ m. If the average pore size is less than 1 ⁇ m, Clogging of the filter F1 becomes significant. On the other hand, if the average pore diameter exceeds 50 m, fine particles cannot be collected, and the collection efficiency will be reduced.
- the porosity of the filter F1 is preferably 30% to 70%, more preferably 40% to 60%. If the porosity is less than 30%, the filter F1 may be too dense and exhaust gas may not be allowed to flow inside. On the other hand, if the porosity exceeds 70%, the number of voids in the filter F1 becomes too large, so that the strength is weakened and the efficiency of capturing fine particles may be reduced.
- the thermal conductivity of the filter F1 is preferably 20 WZmK to 80 WZmK, and the power S is good. Further, the thermal conductivity is preferably 30 W / mK: up to 70 WmK. .
- a total of 16 filters F1 have their outer peripheral surfaces bonded to each other via a ceramic sealing material layer 15.
- the thermal conductivity of the sealing material layer 15 needs to be 0.1 WZmK to 10 WZmK, and more preferably 0.2 W / mK to 2 WZmK.
- the thermal conductivity is less than 0.1 WZmK, the thermal conductivity of the sealing material layer 15 cannot be sufficiently improved, so that the sealing material layer 15 still has a large thermal resistance and the heat between the filters F1 Conduction is hindered. Conversely, if an attempt is made to obtain a material having a thermal conductivity exceeding 10 WZmK, performance such as adhesiveness and heat resistance may be impaired, which may actually make production difficult.
- the thickness t 1 of the sealing material layer 15 is 0.3 mn! To 3 mm, and more preferably 0.5 mm to 2 mm.
- the sealing material layer 15 When the thickness t1 exceeds 3 mm, even if the thermal conductivity is high, the sealing material layer 15 still has a large thermal resistance, and heat conduction between the filters F1 is hindered. In addition, since the ratio of the filter F1 in the aggregate 9 is relatively reduced, the filtration capacity is reduced. Conversely, if the thickness t 1 of the sealing material layer 15 is less than 0.3 mm, a large thermal resistance is not obtained, but the filters F 1 Insufficient adhesive force is applied, and the aggregate 9 is easily broken.
- the sealing material layer 15 is composed of at least an inorganic fiber, an inorganic binder, an organic binder, and inorganic particles, and binds the inorganic fibers and the inorganic particles that are three-dimensionally intersecting to each other via the inorganic binder and the organic binder. It is desirable that it be made of an elastic material.
- Examples of the inorganic fibers contained in the sealing material layer 15 include at least one or more types of ceramic fibers selected from silica-alumina fibers, mullite fibers, alumina fibers, and silicium fibers. Among these, it is particularly desirable to select silica-alumina ceramic fibers. This is because the silica-alumina ceramic fiber has excellent elasticity and an effect of absorbing thermal stress.
- the content of the silica-alumina ceramic fiber in the sealing material layer 15 is from 10% by weight to 70% by weight, preferably from 10% by weight to 40% by weight, more preferably from 20% by weight on a solid basis. % To 30% by weight. Content is 10 weight. If it is less than / 0 , the effect as an elastic body is reduced. On the other hand, the content is 70 weight. If it exceeds / 0 , not only will the thermal conductivity decrease, but also the elasticity will decrease.
- the shot content in the silica-alumina ceramic fiber is 1 weight 0 /. 110% by weight, preferably 1% to 5% by weight, more preferably 1% to 3% by weight.
- One shot content If the content is less than / 0 , it is difficult to manufacture, and if the shot content exceeds 50% by weight, there is a disadvantage that the outer peripheral surface of the filter F1 is damaged.
- the fiber length of silica-alumina ceramic fiber is lmn! 1100 mm, preferably lmm ⁇ 50 mm, more preferably 1 mm ⁇ 20 mm. If the fiber length is less than 1 mm, there is a disadvantage that an elastic structure cannot be formed. If the fiber length exceeds 100 mm, there is a disadvantage that the fibers are pilled and the dispersibility of the inorganic fine particles is deteriorated. If the fiber length exceeds 100 mm, it is difficult to reduce the thickness of the sealing material layer 15 to 3 mm or less, and it is difficult to improve the thermal conductivity between the filters F1. It will be difficult.
- At least one or more colloidal sols selected from silica sol and alumina sol are desirable.
- the reason is that silica sol is easily available and easily becomes Sio 2 by firing, so that it is suitable as an adhesive in a high temperature region.
- silica sol has excellent insulating properties.
- the content of the silicic acid sol in the sealing material layer 15 is 1% to 30% by weight, preferably 1% to 15% by weight, more preferably 5% to 9% by weight on a solid basis. /. It is. When the content is less than 1% by weight, the adhesive strength is reduced, and conversely, the content is 30% by weight. /. If the content exceeds 3, thermal conductivity will be reduced.
- a hydrophilic organic polymer is preferable, and at least one or more polysaccharides selected from polyvinyl alcohol, methinoresenolose, ethylsenorelose and carboxycellulose are preferred. Is more preferred.
- carboxymethylcellulose imparts suitable fluidity to the sealing material layer 15 and therefore exhibits excellent adhesiveness in a normal temperature region.
- the content of carboxymethylcellulose in the sealing material layer 15 is from 0.1% by weight to 5.0% by weight, preferably from 0.2% by weight to 1.0% by weight, more preferably from 0.2% by weight as solids. 4 weight. /. ⁇ 0.6 weight. /. It is. 0.1 weight.
- a content of less than / 0 makes it difficult to sufficiently suppress migration.
- the term “migration” refers to a phenomenon in which when the sealing material layer 15 filled between the objects to be sealed hardens, the binder in the sealing material layer 15 moves as the solvent is dried and removed. Means On the other hand, the content is 5.0 weight. /. If the temperature exceeds the limit, the organic binder is burned off by the high temperature, and the strength of the seal material layer 15 decreases.
- the inorganic particles contained in the sealing material layer 15 are at least one kind of inorganic powder selected from silicon carbide, silicon nitride, and boron nitride, or a low-property material using whiskers.
- silicon carbide silicon nitride, and boron nitride
- a low-property material using whiskers Such carbides and nitrides have very high thermal conductivity. The reason is that the ceramic fiber surface ⁇ intervenes on the surface and inside of the colloidal sol and contributes to the improvement of the thermal conductivity.
- silicon carbide powder it is particularly preferable to select silicon carbide powder.
- silicon carbide powder since the filter F1 to be sealed is made of porous silicon carbide, it is preferable to select the same type of silicon carbide powder.
- the content of the silicon carbide powder is from 3% to 80% by weight, preferably from 10% to 60% by weight, more preferably from 20% to 40% by weight in terms of solid content. is there. Content is 3 weight.
- the ratio is less than / 0 , the thermal conductivity of the sealing material layer 15 decreases, and the thermal resistance of the sealing material layer 15 still has a large value.
- the content exceeds 80% by weight, the adhesive strength at high temperatures decreases.
- the particle size of the silicon carbide powder is 0.01 ⁇ ! ⁇ 100 m, preferably 0. ⁇ ! To 15 m, more preferably 0.1 ⁇ m to 10 ⁇ m.
- the particle size exceeds 100 m, the adhesive strength and the thermal conductivity decrease.
- the particle size is less than 0.1 ⁇ , the cost of the sealing material layer 15 increases.
