摘要： A method and apparatus is disclosed for the denitration of an NOx-containing untreated gas from an off-gas source (7). According to the method ammonia (6) is introduced into the NOx-containing untreated gas in known manner prior to passage through a denitration reactor (2) packed with a catalyst effective to cause the catalytic reduction of the nitrogen oxides in the presence of ammonia. According to the invention a portion of the untreated gas (4) is caused to bypass the denitration reactor (2) and is subsequently recombined with the treated gas from the reactor. Control means (5) are provided for regulating the flow rate of the untreated bypass gas stream.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling NH 3 (ammonia) injection into catalytic denitrification equipment capable of inexpensively controlling the NH 3 injection so as to keep the outlet concentration of NO X constant with a small variation range. SOLUTION: In the method for controlling NH 3 injection into catalytic denitrification equipment, NO X in waste gas discharged from a waste incinerator is removed by an ammonia catalytic reduction method. Therein, the upper limit, intermediate and lower limit values of ammonia quantity injected into the inlet of the catalytic denitrification equipment and the outlet concentration of NO X of the catalytic denitrification equipment are set beforehand. When the measured value of the outlet concentration of NO X of the catalytic denitrification equipment exceeds the set value of the outlet concentration of NO X , the NH 3 quantity in the range calculated from the deviation of the outlet concentration of NO X and the set value of the outlet concentration of NO X and between the upper limit value and the intermediate value is injected instantly and pulsatively to the inlet of the catalytic denitrification equipment, and the outlet concentration of NO X of the catalytic denitrification equipment is kept constant. When the measurement of the outlet concentration of NO X of the catalytic denitrification equipment is smaller than the set value of the outlet concentration of NO X , the ammonia quantity in the range calculated from the deviation of the outlet concentration of NO X and the set value of the outlet concentration of NO X and between the intermediate value and the lower limit value is injected instantly and pulsatively to the inlet of the catalytic denitrification equipment and the outlet concentration of NO X of the catalytic denitrification equipment is kept constant.

摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently and economically treating a flue gas discharged from an incineration apparatus for municipal refuses or industrial wastes. SOLUTION: A flue gas discharged from an incineration apparatus for municipal refuses, industrial wastes, etc., is subjected to temperature decrease with a boiler 11 and a gas-cooling tower and then is subjected to dust removal with a dust collector 12. At the downstream side of the dust collector 12, a corrosion- resistant heat exchanger 13 and then a wet-type smoke-cleaning apparatus 15 are installed. After the flue gas at the outlet of the smoke-cleaning apparatus 15 is introduced into the heat exchanger 13 to be subjected to heat exchange, the gas is supplied to a catalyst tower 17, if necessary through a flue gas heater 16. Since the heat exchanger installed at the downstream side of the dust removal uses tubes made of corrosion-resistant glass, the exchanger is resistant to an acidic gas. Since the flue gas supplied to the catalyst tower is subjected to heat exchange with the flue gas of a relatively high temperature before the temperature decrease, treatment efficiency can be elevated. Thus, the amount of steam used can be decreased to a large extent.

摘要： PURPOSE:To uniformly move the moving-method grains by providing a flow straightening body for moving-bed grains with a fixed apex angle at the upper and lower parts and having an almost rhombic section practically on the center line of the moving bed in the vicinity of the boundary between the moving bed and hopper part. CONSTITUTION:Grains are continuously supplied to the moving bed 4 and brought into countercurrent or cocurrent contact with a fluid, and various reactions are carried in out in the moving bed 4. The hopper part 1 for discharging the grains is also provided. The rhombic flow straightening body 3 with an apex angle of (90-theta)X2+ or -5 deg. (theta is the angle of the inclined hopper part to the horizontal direction and is smaller than 90 deg.) at the upper and lower parts is provided in the bed 4 practically on the center line of the bed 4 in the vicinity of the boundary between the bed 4 and hopper par 1 as the means for preventing the formation of an immobilized region or as the means for minimizing the formation of the region. As a result, the moving pattern of the moving- bed grains is practically uniformized, and the reaction efficiency in various reaction systems is significantly improved.

摘要： PURPOSE:To provide a fixing device which controls the displacement of a reactor by horizontal force easily by placing an imaginary fixing point at the center of the reactor, and controlling the plugs profected from the respective beams in the four sides in the lowermost part of the reactor by means of stoppers provided to the respective beams of a stand from both sides. CONSTITUTION:Lugs 8 for stoppers are projected to the central parts of the beams 7 at four sides in the bottom part of the reator, and stoppers 10 controlling movement in the longitudianl direction of the beam of the lugs 8 are provided in the central parts of beams 9 of a stand on both sides of the lugs 8. The gaps (overlap parts) of the stoppers 10 and the lugs 8 are set suitably in consideration for thermal expansion of the reactor, for example, at about 50-100mm.. With the above- mentioned constitution, when horizontal force such as seismic force, wind pressure or the like is applied upon the reactor, the lugs 8 abut on the stoppers 10, thereby controlling the displacement of the reactor by the horizontal force. When horizontal force in, for example, an X direction, is exerted, the lugs 8 abut on the stoppers at the points D, E, thereby controlling the displacement of the reactor. Since the respective displacement control parts are provided to the beams on the four sides, the reactor assumes the same state as that of the provision of a fixed point at the center A and the reactor is fixed to the stand surely.
摘要翻译：目的：提供一种定影装置，其通过将假想固定点放置在反应堆的中心处，容易地通过水平力控制反应堆的位移，并且控制从位于反应堆的最下部分的四个侧面中的各个横梁的插头反应器通过从两侧设置到支架的各个梁的止动件。构成：用于止动件的凸耳8在转子的底部的四侧投射到梁7的中心部分，并且控制凸耳8的梁的纵向方向上的移动的止动件10设置在考虑到反应器的热膨胀，止动件10和凸耳8的间隙（重叠部分）适当地设定在例如约50-100mm处。对于上述结构，当在反应堆上施加诸如地震力，风压等的水平力时，凸耳8抵靠在止动件10上，从而通过水平力来控制反应器的位移。当施加例如X方向的水平力时，凸耳8在点D，E处邻接止动件，从而控制反应器的位移。由于各个位移控制部分设置在四侧的梁上，所以反应器呈现与设置在中心A处的固定点相同的状态，反应器可靠地固定在支架上。
