摘要： PURPOSE:To reduce remarkably the dust concn. contained in an exhaust gas at an outlet of a fluidized bed type adsorption tower by gas-cleaning previously granulr adsorbents which are flowed into the adsorption tower in the inside of a supplying pipe of the adsorbents in the adsorption tower. CONSTITUTION:The gas in the inside of an adsorption tower 2 which is sucked with a fan 16 is risen while allowing to contact with carbonaceous granular adsorbents 3 and is entered a dust collector 15 in accompanying with fine power, and the dust is removed. The cleaned gas is elevated in pressure by said fan and is mixed with an exhaust gas 1 from a boiler or the like at an inlet part of the adsorption tower. Herein, the flow velocity of gas which is risen in the inside of the dust removing pipe must be controlled to the degree so that the falling adsorbent granules are not fluidized. The harmful components contained in the exhaust gas 1 are adsorbed in the adsorption tower.

摘要： PURPOSE:To prevent the accumulation of dust to the louver part in a gas inlet side and the excessive rising in pressure loss, by eliminating the stay of the particulate substance on a louver to bring a good moving state. CONSTITUTION:In a moving layer reaction tank wherein a particulate substance 12 is held in a packed state by a louver structure and brought into contact with gas 25 passing louvers whole moved from above to below, sub-louvers 18, 19 each having an inverted V-shape cross-sectional area are provided to the insides of main louvers 17, which are arranged in one line in a vertical direction, in one line in parallel to the louvers 17 in order to hold the substance 12 in a packed state. The one side 18 of each sub-louver originates from the intermediate position in the height direction of each stage and forms a reverse gradient with respect to each louver 17 toward the inside of each louver 17 while the other side 19 is directed to a vertical downward direction from the apex of the V-shape and all stages are arranged so as to be present in the same vertical plane as well as the lower end of this vertically and downwardly directed side is prevented from contacting with the apex of the V-shape in the adjacent lower stage.

摘要： PURPOSE:To uniformize the amount of gas by mounting packing material supply and taking-out ports to the respective upper and lower parts of a moving bed unit and forming the long side of wall into an air permeable structure and the short side thereof into an airtight structure. CONSTITUTION:Waste gas receives the addition of ammonia gas on this side of a gas inlet to enter an inside gas passage 59 from the gas inlet 56 and passes through an adsorbing material moving bed unit 54, wherein activated coke moves from above to below as an orthogonal stream and, after COx and NOx in the gas are removed by the contact with activated coke, the treated gas issues to an outside gas passage 58 to be discharged out of the system through a gas outlet 57. Activated coke is supplied to the adsorbing material moving bed from an adsorbing material hopper 63 through adsorbing material supply piping 64 to move from above to below in the moving bed and the activated coke having adsorbed SOx is taken out from the adsorbing material taking-out port 66 of the moving bed. By this method, the uniformization of the falling of a packing material becomes easy.

摘要： PROBLEM TO BE SOLVED: To provide an economically profitable device by simplifying the equipment, making small the installing area thereof, lowering the installation cost thereof, and also simplifying the regeneration treatment therefor. SOLUTION: An exhaust gas is caused to flow through a moving bed adsorber 1 packed with carbonaceous material to perform gas-liquid contact of the carbonaceous material and the exhaust gas and to adsorb and remove dust, sulfur oxide, dioxin, chlorine, and the like contained in the exhaust gas. The carbonaceous material is continuously or intermittently drawn out from the lower part of the adsorber 1 by a constant amount drawing feeder 2 and is sent to a regeneration process by a bucket conveyor 3. There, the adhered dust and the powdered carbonaceous material are removed by a sorter 5 to perform regeneration treatment of the carbonaceous material. The carbonaceous material which has been subjected to the regeneration treatment is fed to the upper part of the adsorber 1 from a hopper 4.

摘要： PROBLEM TO BE SOLVED: To prevent the leakage of a waste gas by renewing an adsorbent by the intermittent operation of a reaction tower and to keep the heights of the devices and entire equipment low. SOLUTION: A quantitative discharger 2, and automatic stop valve A, a closed chamber 3, a quantitative discharger 4 and an automatic stop valve B are provided between the outlet of a reaction tower 1 and a discharge conveyor 5 to form a first closed system. An automatic stop valve A, a closed chamber 10, an automatic stop valve B and a hopper 11 are furnished between a supply conveyor 9 and the supply port of the reaction tower 1 to form a second closed system. The supply port and discharge port of the gas for making the inside of each closed system a dry atmosphere are connected to each system. The reaction tower is intermittently operated to intermittently renew the adsorbent, the two automatic stop valves A and B of the first closed system or second closed system are alternately opened in synchronization with the renewal, and the adsorbent is discharged from or supplied to the reaction tower without discharging the waste gas.

摘要： PROBLEM TO BE SOLVED: To completely remove ammonia contained in desorbed gas. SOLUTION: An exhaust gas is caused to flow through an adsorber 1 packed with carbonaceous material to form a moving bed to perform solid-liquid contact of the carbonaceous material and the exhaust gas and to remove nitrogen oxides and other harmful materials contained in the exhaust gas. The carbonaceous material whose activity has been lowered is drawn out from the adsorber 1 and is fed to an ammonia removing column 2 and desorbed gas and oxygen containing gas generated in a regenerator 3 is fed to the ammonia removing column 2 to perform solid-gas contact with carbonaceous material and to remove ammonia contained in the desorbed gas. The carbonaceous material is drawn out from the ammonia removing column 2 and is fed to the regenerator 3 to perform heating/regenerating treatment of the carbonaceous material and to desorb and remove the harmful material. The carbonaceous material is drawn out from the regenerator 3 and is fed to a classifier 4 to remove dust and powdered carbonaceous material. In this way, the regenerating treatment of the carbonaceous material is performed, and also ammonia contained in the desorbed gas is removed.
