摘要： PURPOSE:To produce an effective removal effect in a subject method which removes solid adhered to a catalyst bed by the aid of air current flowing at a rapid speed into an exhaust gas denitrating device by providing a long slit nozzle throughout almost a full length of an injection pipe, and injecting a continuous air stream therefrom. CONSTITUTION:Denitration catalyst beds 1, 1' consist of catalyst blocks having a honeycomb-shaped perforation, and gas to be treated is exhausted through an outlet 9 after it passes through the catalyt bed 1, 1' successively. A part of solid, contained in the exhaust gas 3, adheres to the inlet edge surfaces and catalyst surfaces 2. A soot blow device, which is fitted into a guide material 13 and in which an injection pipe 10 can move in the direction of an arrow mark 8 parallel to the catalyst bed, is mounted in front of the catalyst bed. A pressurized air supplied from a feed pipe 6 is jetted to the catalyst surface through a slit nozzle 7 formed in the injection pipe 10 to remove extraneous matter. In this method, the pressurized air is injected uniformly, whereby the injection pipe can approach closer to the catalyst surface and the consumption amount of air can be reduced.

CONSTITUTION:Heat-resistant packings 2 of an L-shape formed by ''Kaowool '', asbestos, etc. are disposed on the upper stream side and lower stream side of the gas passage surfaces of single catalyst layers 1, and the catalysts 1 and heat-resistant packings 2 are alternately combined and stacked, whereby these are packaged into one body. Further, retaining fittings 4 are applied from the outer side of the packing materials 2 at said side edge parts on at least one side of the gas inlet side or outlet side of the gas passage surfaces of the single catalysts and the fittings 4 are fixed to a frame structural body 5. The packings 2 are used at about 2-3mm. thicknesses corresponding to the thickness of the outside wall part of the catalysts in order to provide protection to the end face parts of the catalysts 1 and prevent the deviation of the catalysts in the direction perpendicular to the gas flow 3.

摘要： PURPOSE:To economically and effectively remove deposition, accomulation and bridge formation in a packed layer by specifying the distance between gas jet nozzles and the packed layer to be from 0.2-10m and the gas flow velocity at the inlet section of packing material during the gas injection to 5-40m/sec. CONSTITUTION:The distance between the solid-gas catalytic packed layers 2 packed with a filling material having a plurality of gas passages extending in a gas flow direction and the nozzles 4 from which the gas introduced from outside of the system is jetted is regulated to 0.2-10m; the flow velocity of the gas when jetted at the injet section of the packing material is 5-40m/sec., and while the jetting position of the gas jet nozzles 4 is fixed or moved by directing toward the packed layer 2 and the packed layer surfaces at their inlet or outlet sides, the gas is jetted from the gas jet nozzles 4 to remove the dust deposition 6 or the like. Each of the packed layers 2 is made of a packing material having gas passages in the form of a lattice, honeycomb or the like, and a plurality of such packed layer 2 are package and arranged to be supported by the outside wall of the duct for the packing material.
