Definitions

  • the present invention relates to a particulate removing apparatus and more particularly to the particulate removing apparatus which is preferable to be adapted to collect particulates contained in exhaust gas from an internal combustion engine such as an diesel engine or a like used for a diesel engine vehicle, an electric generator, an agricultural implement, or like by using a heater and a filter and to burn and remove the collected particulates and to the diesel engine vehicle equipped with the particulate removing apparatus.
  • an internal combustion engine such as an diesel engine or a like used for a diesel engine vehicle, an electric generator, an agricultural implement, or like by using a heater and a filter and to burn and remove the collected particulates and to the diesel engine vehicle equipped with the particulate removing apparatus.
  • NOx nitrogen oxide
  • a like which mainly contains nitrogen dioxide being considered as a carcinogen.
  • Exhaust gas from a diesel engine vehicle contains a large amount of carbon particulates (so-called black smoke) .
  • the carbon particulates after having been puffed out through an exhaust gas path in the air, remain suspended in the air for a long time and, in the end, settle, in a form of soot or a like, onto a floor surface, road surface, clothes, or a like.
  • a black smoke removing apparatus is disclosed in, for example, Japanese Model Utility Application Nos. Sho 61 - 55114 and Sho 61 - 84851 in which, as an apparatus to protect environmental air from diesel black smoke pollution, a black smoke removing filter made up of a metal fiber, a honeycomb-shaped element or a like is attached to an exhaust gas path of a vehicle-mounted diesel engine.
  • a black smoke removing filter made up of a metal fiber, a honeycomb-shaped element or a like is attached to an exhaust gas path of a vehicle-mounted diesel engine.
  • a diesel particulate removing.apparatus As a means for solving the problem of clogging of a mesh caused by black smoke, a diesel particulate removing.apparatus is disclosed in, for example, Japanese Patent Application Laid-open Nos. Hei 2 - 173310, Hei 6 - 212954 and Hei 8 - 1935'09 in which a filtering function is regenerated by burning collected diesel particulates.
  • the apparatus of this type is made up of a cylindrical container having an entrance and an exit of exhaust gas, a heater mounted on a side of the entrance of the cylindrical container, a porous foam filter arranged so as to be adjacent to a rear portion of the heater, and a catalyst supporting filter arranged so as to be adjacent to a rear portion of the porous foam filter.
  • the particulate removing apparatus having such the configurations as above is so configured that exhaust gas introduced from the entrance comes into contact with the heater made of ceramic or metal and already heated, causing ignition and burning of the particulates and the burnt particulates are then collected by the porous foam filter and by the catalyst supporting filter. At this time point, the heat generated by the heater and given off by the exhaust gas is transmitted to the porous foam filter and lets unburned particulates collected by the porous foam filter be ignited and burnt.
  • a particulate removing apparatus being capable of regenerating, with ease and at a low cost, a function of a filter in which advanced clogging of its mesh has occurred and a diesel engine vehicle equipped with the diesel particulate removing apparatus. It is another object of the present invention to provide a particulate removing apparatus which is capable of preventing explosive burning of particulates in a gas caused for some reason and of preventing, even if the explosive burning occurs, burning of the diesel particulate removing apparatus itself and a diesel engine vehicle equipped with the diesel particulate removing apparatus.
  • a diesel particulate removing apparatus including:
  • a preferable mode is one wherein a safety valve is mounted in the inner cylinder, which is used to let the diesel exhaust gas flow into the emergency bypass flow-path when pressure in the inner cylinder increases rapidly.
  • a preferable mode is one wherein apertures with lids to attach and detach the two or more filters are mounted on side surfaces of the outer cylinder.
  • a preferable mode is one that wherein includes:
  • a preferable mode is one wherein gaskets are inserted between the two or more filters, between one of the two or more filters placed on a most upstream side and the flow-in cylinder, and between one of the two or more filters placed on a most downstream side and the flow-out cylinder, which make up the inner cylinder of a sealed structure.
  • a preferable mode is one wherein a joint cylinder with the gaskets to connect the two or more filters each other is mounted in the inner cylinder.
  • a preferable mode is one wherein aperture portions with lids to attach and detach each of the two or more filters are formed on a side surface of the outer cylinder.
  • a preferable mode is one wherein, to mount the inner cylinder, lid portions of the apertures for attaching and detaching are opened and then each of the filters is inserted from each of the apertures for attaching and detaching and, to disassemble the inner cylinder, an attaching and detaching unit to take out each of the two or more filters from each of the apertures for attaching and detaching is used.
  • a preferable mode is one wherein the attaching and detaching unit. has a single long bolt or two or more long bolts.
