    • PROBLEM TO BE SOLVED: To enable an apparatus, which treats a halogen compound by using a catalyst, to perform a process for exchanging the catalyst in a short time. SOLUTION: The treatment apparatus of the halogen compound is provided with: a preheater in which a gas to be treated containing the halogen compound is heated to a prescribed reaction temperature; a reactor in which incorporating the catalyst for decomposing the halogen compound incorporated in the heated gas is decomposed; and a cooler in which a decomposed gas discharged from the reactor is cooled, and is characterized in that the preheater is provided with a cooling water atomizing device therein. Cooling water is atomized in a preheating tub in the preceding stage of a reaction tower filled with the catalyst and the temperature decline of the preheater and the reactor filled with the catalyst is accelerated.

    • PROBLEM TO BE SOLVED: To reduce the amount of water used in current methods of removing a large amount of silicon compounds from the PFC-containing tail gas incoming into a catalytic PFC decomposition apparatus by the use of a wet removal apparatus in a stage preceding to the reactor, which methods usually require a large amount of water. SOLUTION: An equipment for decomposing the exhaust gas has a wet removing apparatus for removing solids contained in the gas to be treated, a preheater heating the gas to be treated and a reactor decomposing the gas to be treated. The wet removing apparatus has two or more spray nozzles, including an upstream mist-forming spray nozzle and a downstream water-film-forming spray nozzle. Other spray nozzles are arranged within the wet removing apparatus so as to bring sprayed water efficiently into contact with the gas to be treated containing the silicon compounds. Mist containing the silicon compounds produced in reaction with water is prevented from flowing into the reactor having a catalyst layer. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:为了减少在通过使用湿式除去装置进入催化PFC分解装置的从含PFC的尾气中除去大量硅化合物的现有方法中使用的水量 反应器之前的阶段,哪些方法通常需要大量的水。 解决方案:用于分解废气的设备具有用于除去待处理气体中所含的固体的湿式除去装置,加热待处理气体的预热器和分解待处理气体的反应器。 湿式去除装置具有两个以上的喷嘴,包括上游雾化喷雾喷嘴和下游的成膜喷嘴。 湿式去除装置内设有其他喷嘴,以使喷雾水与含硅化合物的待处理气体有效接触。 防止含有与水反应生成的硅化合物的雾化流入具有催化剂层的反应器中。 版权所有(C)2006,JPO&NCIPI
