    • PROBLEM TO BE SOLVED: To remove nitrogen oxides in a mixed gas by roughly horizontally running the mixed gas, while facilitating carrying work or exchanging work of an adsorbent, in a nitrogen oxides removal apparatus. SOLUTION: Multiple adsorbing units 20 are arranged in all directions in a nitrogen oxides adsorbing part 12 of the nitrogen oxides removal apparatus wherein a gas introducing part 10, a nitrogen oxides adsorbing part 12 and a gas delivering part 14 are nearly horizontally arranged. Each adsorbing unit 20 is provided with an adsorbing member 22 surrounding an inner flow passage 30, and an outer frame 24 surrounding the adsorbing member 22 and forming an outer passage 32 therebetween. The inner passage 30 is opened to form a gas inlet 38 and the outer passage 32 is blocked at one axial end of the adsorbing unit. At the other end, the inner passage 30 is blocked and the outer passage 32 is opened to form a gas outlet 42. The mixed gas passes through the adsorbent layer of the adsorbent member 22 from the gas inlet 38 and reaches the gas outlet 42. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:通过大致水平地运行混合气体来除去混合气体中的氮氧化物,同时便于在氮氧化物去除装置中进行工作或更换吸附剂的工作。 解决方案:在氮氧化物去除装置的氮氧化物吸附部分12中,将多个吸附单元20全向布置,其中气体引入部分10,氮氧化物吸附部分12和气体输送部分14几乎水平地布置 。 每个吸附单元20设置有围绕内部流动通道30的吸附构件22和围绕吸附构件22并在其间形成外部通道32的外框24。 内部通道30打开以形成气体入口38,并且外部通道32在吸附单元的一个轴向端部被阻塞。 在另一端,内通道30被封闭,外通道32打开以形成气体出口42.混合气体从气体入口38通过吸附剂构件22的吸附剂层并到达气体出口42。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a stratal gas concentration measuring device and a stratal gas concentration measuring method by which the concentration of a gas element contained in a stratum can be grasped in a short time as the stratum is excavated by shield excavation or boring.
      SOLUTION: The stratal gas concentration measuring device includes a gas/liquid separating unit which separates gas elements from a fluid material in a stratum or from muddy water containing earth and sand produced by excavating the stratum, a gas retaining unit which retains the separated gas elements, a gas concentration measuring unit which measures the gas concentration of a target gas element among the gas elements retained in the gas retaining unit in correspondence to an elapsed time from the start of measurement, a stratal gas concentration corresponding information deriving means which derives information corresponding to a gas concentration in the stratum, based on the tendency of a change in the gas concentration in the gas retaining unit that is defined by the relation between the gas concentration measured by the gas concentration measuring unit and the elapsed time.
