好適な排ガス煙道の反応装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reaction device for an exhaust gas flue, and in particular to an exhaust gas smoke suitable for flue protection when a reducing agent for exhaust gas denitrification is added as an aqueous solution spray. Regarding the road reactor.

施されていなかった。Nitrogen oxides (NOx) generated from combustion equipment that uses fossil fuels such as coal and oil are harmful, and efforts are being made to reduce emissions as much as possible. A common method for reducing nitrogen oxides is to first suppress their generation, and then add a reducing agent such as ammonia to react with the generated nitrogen oxides to render them harmless. For example, in a large boiler at a thermal power plant, NOx generation is first suppressed by low NOx combustion, then ammonia is added to the exhaust gas, and the NOx is treated in a denitrification reactor before being released into the atmosphere. For small boilers used for heating in urban areas, the amount of exhaust gas emitted per unit is small and laws and regulations are lenient, so treatment of nitrogen oxides in the exhaust gas has not been carried out.

要である。Recently, however, pollution of urban air by exhaust gas has increased, and laws and regulations have become stricter for small-scale exhaust gas generating sources in urban areas, and there is a trend for smaller exhaust gas denitration equipment to be installed to treat nitrogen oxides. Generally, when making such chemical equipment small-scale, simply scaling it down will cause problems and generate heat and heat.
A mechanical reexamination that takes into account the transfer of mass and momentum is necessary.

すことになる。In large denitrification equipment, ammonia gas diluted with exhaust gas is injected by installing many reducing agent injection ports in a huge flue cross section that people can pass through, and the effect of the injected ammonia gas on the wall is ignored. can. However, as the device becomes smaller, the diameter of the flue becomes smaller and the area of the flue wall that comes into contact with a unit amount of gas becomes larger, increasing the chances that the added reducing agent will come into contact with the wall surface without being uniform. This increases the chance that the wall surface will be partially cooled, since the reducing agent, which is usually much cooler than the exhaust gas, contacts the wall surface in a localized manner.

して壁面にＭ積される欠点が生じる。In the above-mentioned conventional technology, when a reducing agent whose temperature is lower than that of the exhaust gas and is normally equal to the atmospheric temperature is mixed with the exhaust gas, local cooling occurs on the flue wall surface of the small-diameter flue, and the tar in the exhaust gas, There is a problem that the risk of adhesion of scales such as ammonium sulfate increases. This problem is less of a problem when a gas such as ammonia is used as the reducing agent. However, the temperature required for the denitration reaction depends on the type of denitration catalyst, and in order to lower the temperature of the exhaust gas to that temperature, an aqueous solution of ammonia, urea, etc. may be used as a reducing agent, which poses a major problem. Become. In other words, even if an aqueous solution is sprayed into minute water droplets, those that collide with the flue wall before mixing with gas and evaporating tend to aggregate and form a liquid film, and the temperature of the wall surface increases as it absorbs the latent heat of vaporization during vaporization. If the local temperature drop is large, a problem arises in that the strength of the wall surface gradually decreases due to thermal shock. Furthermore, when the reducing agent is urea, there is a further drawback that the reducing agent itself is deposited as scale on the wall surface.
本発明の目的は、上記従来技術の欠点をなくし、還元剤

排ガス煙道の反応装置を提供することにある。An object of the present invention is to provide a reactor for an exhaust gas flue, which can eliminate the drawbacks of the prior art described above and prevent scale from adhering to the flue wall in the reducing agent mixing section and from reducing the strength of the flue wall due to thermal shock. Our goal is to provide the following.

を特徴とする排ガス煙道の反応装置により達成される。The above purpose is to purify the exhaust gas by adding a substance that reacts with a specific component in the exhaust gas to the flue gas flue and causing the reaction to occur in the downstream flue or reactor. This is achieved by an exhaust gas flue reactor characterized in that the flow is divided into the inside and outside of the inner cylinder, and a reducing agent injection nozzle for injecting the reactant is arranged inside the inner cylinder.

が加わることもないので問題となることはない。The low-temperature, high-concentration reducing agent injected into the exhaust gas from the reducing agent injection nozzle is blocked by the inner cylinder and does not come into contact with the flue wall, but is sufficiently mixed with the exhaust gas in the inner cylinder, diluted, and released into the exhaust gas. After coming out of the tube, it comes into contact with the flue wall. On the other hand, the inner cylinder wall surface is locally cooled by the injected reducing agent, but unlike the flue wall surface, it is heated by the exhaust gas flowing outside, so the temperature drop on the inner cylinder wall surface is small, and therefore there is less scale adhesion. . Further, even if a thermal shock is applied to the inner cylinder, causing a decrease in its strength, this will not be a problem because unlike the flue wall, no load is applied to the inner cylinder from the outside.
以下、本発明を実施例を用いて詳細に説明する。 Hereinafter, the present invention will be explained in detail using examples.

て煙突１５より排出される。FIG. 1 is an apparatus system diagram when the exhaust gas flue reaction apparatus according to the present invention is applied to exhaust gas denitrification of a diesel engine. The inner cylinder 2, which is a feature of the present invention, is disposed within the flue pipe 4 and downstream of the reducing agent injection nozzle 6. The exhaust gas generated by the diesel engine 11 is transferred to the flue pipe 4.
The flow is divided into the inside and outside of the inner cylinder by the inner cylinder 2, and after the reducing agent is injected into the inner flow from the reducing agent injection nozzle 6, it is sent to the denitrification reactor 12, and the exhaust gas is treated on the denitrification catalyst. After the nitrogen oxides and reducing agent inside react and are purified, the waste heat is recovered in the heat exchanger 13, passes through the muffler 14, and is discharged from the chimney 15.

め、還元剤とともに水が噴霧される。The temperature of the exhaust gas generated by the diesel engine 11 varies depending on the operating condition, but is usually 450 to 600°C. On the other hand, a suitable temperature for the denitrification reactor 12 filled with, for example, a titanium-based denitrification catalyst is 350 to 500°C. usually,
If only the reducing agent is added, the exhaust gas temperature decreases by 5° C., so water is sprayed together with the reducing agent in order to lower the exhaust gas temperature by about 100° C.

This device includes a flue pipe 4, a reducing agent injection nozzle 6 provided inside the flue pipe, an inner cylinder 2 surrounding the injection nozzle of the injection nozzle 6 and arranged in the gas flow direction, and an inner cylinder 2 arranged in the gas flow direction. It is mainly composed of blades 1 and 3 provided on the inner and outer walls of the downstream side. The blades 1 on the inner wall of the inner cylinder are provided in a spiral shape with an inclination to swirl the flow of gas in the inner cylinder, and the blades 3 on the outer wall of the inner cylinder swirl the gas on the outside in the opposite direction to the gas inside. It is provided with an inclination at the opposite angle to the inside to make it easier to move.
上記構成において、排ガスは煙道配管４内を下から上へ

液が旋回して噴霧される。In the above configuration, the exhaust gas flows from the bottom to the top in the flue pipe 4 (Fig. 2), and is divided into two by the inner cylinder 2 into the inner side and the outside of the inner cylinder, and the inner flow is injected with a reducing agent aqueous solution from the reducing agent injection nozzle 6. swirls and is sprayed.

って異なるものの、内筒２は局所的に水の沸点である温
度１００℃まで低下する危険性がある。The atomized reducing agent aqueous solution and exhaust gas are further swirled by the blades 1 on the inner wall of the inner cylinder downstream, and are sent out of the inner cylinder 2. On the other hand, the exhaust gas flowing outside the inner cylinder 2 heats the inner cylinder 2 and the blades 3 on the outer wall of the inner cylinder, is simultaneously swirled by the twist of the blades 3, and at the outlet of the inner cylinder 2 is swirled in the opposite direction to the inner gas. It collides with and mixes with the gas and reducing agent inside. Since the water droplets from the reducing agent injection nozzle 6 collide with the inner wall of the inner cylinder 2, the temperature of the inner cylinder 2 locally reaches up to 100°C, which is the boiling point of water, although it varies depending on the size of the water droplets, the injection condition, and the gas flow. There is a risk of decline.

。なお、内筒２は煙道配管４によって周囲の荷重から保
護されるので強度を必要としない。However, since the inner cylinder 2 is heated by the gas outside, the wall surface temperature is not cooled as much as when no gas flows outside, and therefore scale adhesion and thermal shock are reduced. The flue pipe 4 is protected from propellants by the inner cylinder 2. Note that the inner cylinder 2 is protected from surrounding loads by the flue pipe 4, and therefore does not require strength.

衝撃により煙道配管の強度低下もない。According to the present invention, since the flue wall surface is not cooled by the added reducing agent, the risk of scale adhesion is reduced, and the flue piping is strengthened by thermal shock caused by repeated local cooling and heating. There is no decline.
