    摘要： PROBLEM TO BE SOLVED: To provide a treating method and a treatment apparatus easily removing nitrogen oxides contained in gas such as air without using a large or complex treatment apparatus, with superior treating capacity and removing rate, causing no spontaneous release of once adsorbed nitrogen oxides.
    SOLUTION: Treating object gas such as air is brought into contact with a water adsorbent to remove moisture contained in the gas, then is brought into contact with a palladium catalyst to remove nitrogen oxides contained in the gas. The treatment apparatus is provided with at least an inlet port of the treating object gas, a packed part of the water absorbent, a packed part of the palladium catalyst, and a discharge port of treated gas, with the gas flowing in this order.

    摘要： PROBLEM TO BE SOLVED: To provide a muffler draining device for a working machine which allows a drain line having superior heat resistance to be reliably installed even when an apparatus or equipment is present at the position below a muffler.
    SOLUTION: In a muffler draining device which is provided to a muffler 12 contained in a hydraulic excavator and equipped with a drain line for discharging water accumulated in the muffler 12 to the outside of a vehicle body, the drain line includes single metal tubing 23 whose one end 23a is connected to the muffler 12 and whose intermediate portion 23c provided continuous to the one end 23a is extended into the space formed between the muffler 12 and a hydraulic pump 11 located below the muffler 12. The intermediate portion 23c of the metal tubing 23 includes a single linear portion 23c1 and a plurality of bent portions 23c2. Also, the muffler draining device includes, for example, a single support bracket 20 which is fixed to the muffler 12 and supports the intermediate portion 23c of the metal tubing 23.

    摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine, provided with water absorption material and NOx absorption material on an exhaust passage in this order from the upstream side, in which prohibition to NOx absorption ability due to water is favorably avoided, so that NOx absorption ability of the NOx absorption material is sufficiently secured.
    SOLUTION: A main exhaust passage 14 is provided to which exhaust gas emitted from the internal combustion engine 10 flows in. A bypass passage 20 is provided to bypass the main exhaust passage 14. The water absorption material 24 and the NOx absorption material 28 are provided on the bypass passage 20 in this order from the closer side to an upstream side connection part 20a. At the time when it is determined that dissociation of water from the water absorption material 24 is started, a changing valve 22 is controlled to prevent exhaust gas from flowing into the NOx absorption material 28.
