In order to improve the environmental quality around the plant, the emission of such nitrogen oxides is controlled. Necessary; Among all the control technologies for treating ruthenium-containing oxide waste gas, Selective Catdytic Reduction (SCR) is widely used in the industry because of its relatively high removal efficiency; The nitrogen oxide-containing waste gas to be treated is first mixed with a reducing agent, and then, in an environment with an appropriate amount of oxygen and an appropriate operating temperature, the reducing agent and the nitrogen oxides react on the catalyst surface to reduce the nitrogen oxides to harmlessness. Helium and water. The temperature of the above chemical reaction is the best for 3〇0~4 thieves. Excessively high or over 16 temperatures, in addition to adversely affecting the catalyst reaction, can also lead to the formation of other by-products such as ammonium dibasic acid, which affects the catalyst.

At this time, the exhaust gas to be treated can enter the first heat storage chamber 225 through the third inlet pipe 225 and the first inlet pipe 221 in sequence. The temperature of the first regenerator 14 is relatively high, so that the internal heat accumulating material 141 can transfer its own thermal energy to the exhaust gas to achieve the effect of preheating the exhaust gas; subsequently, the exhaust gas is introduced into the warming chamber 12, by means of fuel Combustion, the exhaust gas can be heated to the temperature required for the reaction, in addition, the exhaust gas can be thoroughly mixed with the county agent; and then the exhaust gas and the reducing agent will be - and are input to the second heat storage chamber 16 In the case of the surface of the heat storage material 161, the catalysis of the surface of the heat storage material 161 is carried out to generate nitrogen gas and water, and on the other hand, more heat energy is transferred to the heat storage material 161 to raise the temperature; as for the clean air after purification Then through the second discharge pipe 243 The second discharge pipe 245 and discharged to the outside world. The continuous introduction of the exhaust gas to be treated, the temperature of the first heat storage chamber 14 will gradually become lower, and the temperature of the second heat sink 16 will gradually increase, when the temperature of the first heat storage chamber 14 is too low, When the temperature of the second #敎 cavity 16 is high, the main controller 28 will be able to command the introduction of the air intake and discharge valve 248 to switch, and the exhaust gas is changed to the pilot. The second storage 8 M360077 thermal cavity 16 Preheating, and after the warming chamber 12 is heated, enters the first regenerator chamber 14 for denitration reaction' and discharges excess heat energy to the heat accumulating material 141 to the outside; and when the temperature of the second regenerator chamber 16 If the temperature of the first regenerator 14 is high, the main controller 28 can again command the intake valve 228 and the exhaust valve 248 to switch, so that the regenerators 14, 16 take turns to exhaust gas. Preheating and denitration reaction. The first regenerator chamber 14 and the second regenerator chamber 16 can store excess heat energy transmitted by the high-temperature exhaust gas when it is located downstream of the temperature increasing chamber 12, and is required for future preheating of the exhaust gas, so that the heat energy can be more effectively In addition, the purified exhaust gas will be cooled by the heat storage materials 141, 161 before being discharged, and the heat pollution can be effectively avoided. In addition, when the exhaust gas itself has sufficient hydrocarbons and ammonia gas, the reductant supply line 18 and the fuel supply line 2〇 may not be provided, that is, the regenerative denitration reactor 10 It is to use the combustion of hydrocarbons in the exhaust gas to increase the temperature, and to use its own ammonia gas as a reducing agent to carry out denitration reaction with nitrogen oxides, and to achieve the same purification effect. Based on the spirit of this creation, the regenerative denitration reactor has a variety of changes in the configuration of the pipeline; please refer to the second diagram, the regenerative denitration reactor provided by the first example of this creation. 30, having the same temperature as the foregoing embodiment - the temperature increasing chamber 32, a first heat storage chamber 34, a second heat storage month fuel supply line 40, an exhaust gas introduction line 42, an exhaust gas line 44, and a second thermometer 46 and a main controller 48, the only difference being that the reducing agent supply line 38 of the 5H regenerative denitration reactor 30 is connected, that is, the nitrogen oxides to be treated are discarded. 9 M360077 gas is first mixed with the reducing agent, and then preheated through the first regenerator chamber 34 or the second regenerator chamber 36.
