  "title": "Catalytic apparatus",
  "abstract": "A catalytic apparatus characterized in that a plurality of catalyst elements are arranged to form a catalyst block and thus formed catalyst blocks are placed in the passage of exhaust gas. This apparatus permits to form a catalyst bed easily in the exhaust gas duct and ensures a good quality of the formed catalyst bed.",
  "claims": [
    "1. A catalytic apparatus placed in a catalytic bed in passage for exhaust gas comprising: a plurality of catalyst elements arranged to form a catalyst block, said catalyst block being an integrated catalyst unit comprising a plurality of catalyst elements, each comprising a plurality of parallel, spaced apart catalyst plates arranged in a parallelepiped, housed in a box-shaped framework, a gap between the side of adjoining integrated catalyst units being sealed by a seal plate provided at one side of the bottom of the integrated catalyst unit; a plate provided on each of four sides of said block for reinforcing said block; a lattice provided on the discharge side of said block; and a catalyst block transporting means for transporting said catalyst block into and out of said catalyst bed, said catalyst block transporting means comprising: a car; a vertically moving table provided on said car; a rail extending out of said catalyst bed and for guiding said car; and a beam provided in said catalyst bed on which a catalyst block is placed.",
    "2. A catalytic apparatus according to claim 1 in which the gap between the side of the integrated catalyst unit and the reactor wall is sealed by a wall seal plate extending from the reactor wall.",
    "3. A catalytic apparatus placed in a catalyst bed in a passage for exhaust gas comprising: a plurality of catalyst elements arranged to form a catalyst block, said catalyst block being an integrated catalyst unit comprising a plurality of catalyst elements, each comprising a plurality of parallel, spaced apart catalysts plates arranged in a parallelepiped, housed in a box-shaped framework, a space formed between a reactor wall and a pillar member of apparatus provided at a side of the integrated catalyst unit, adjacent thereto is a bridge seal plate that bridges a distance between a top end side of the integrated catalyst unit and the reactor wall; a plate provided on each of four sides of said block for reinforcing said block; a lattice provided on the discharge side of said block; and a catalyst block transporting means for transporting said catalyst block into and out of said catalyst bed, said catalyst block transporting means comprising: a car; a vertically moving table provided on said car; a rail extending out of said catalyst bed and for guiding said car; and a beam provided in said catalyst bed on which said catalyst block is placed.",
    "4. A catalytic apparatus according to claim 1 in which a dust prevention member is provided on a top of a beam of reactor.",
    "5. A catalytic apparatus according to claim 1 in which a gap between the sides of adjoining integrated catalyst units, a gap between a side of integrated catalyst unit and a reactor wall and a space formed between the reactor wall and a pillar member of the apparatus provided at a side of the integrated catalyst unit adjacent thereto are sealed respectively by a seal plate provided at one side of a bottom of the integrated catalyst unit a wall seal plate extending from the reactor wall and a bridge seal plate that bridges a distance between the top end side of the integrated catalyst unit and the reactor wall, a dust prevention member is provided on a top of the beam of reactor.",
    "6. A catalytic apparatus according to claim 5 in which said dust prevention member is a longitudinal member having a cross-section in the form of angle."
