    摘要: An embodiment of an exhaust gas purification device 50 has a function of removing soot adhered to an NOx catalyst 75 arranged inside a cylindrical casing part 74 by injecting pressurized air. The device includes a plurality of air injection nozzles 82 arranged on a side wall of the casing part 74 on an upstream side of the NOx catalyst 75, which are each configured to generate an impulse wave by injecting pressurized air into the casing part 74, wherein the air injection nozzles 82 successively inject one by one an equal flow quantity of pressurized air, for a period t1, at predetermined time intervals.

    摘要: A urea water supply device supplying urea water to purify exhaust gas from an electric power generating engine. The urea water supply device includes: a urea water injector; a urea water flow route in which urea water flows; a clean water supply route in which clean water flows; and a urea water amount adjustment valve and a urea water flow meter provided in the urea water flow route. The clean water supply route merges with the urea water flow route on the downstream side of the urea water amount adjustment valve and the urea water flow meter.

    摘要: An exhaust gas purification device for a ship 1 including: a main path 31 communicated with outside and a bypass path 32 branching off from a midway portion of the main path 31, each of the paths serving as an exhaust gas path 30 of an engine 25 to be mounted in the ship 1. A partition plate 40, by which the main and bypass paths 31, 32 are partitioned from the upstream side to the downstream side in an exhaust gas traveling direction, extends along the exhaust gas traveling direction. The partition plate 40 has a downstream end extended through between an exhaust gas outflow port 49 of the purification casing 33 and an exhaust gas outlet of the main path 31, and the downstream end is formed with an opening 401 to serve as a reverse-flow prevention plate 400.
