Description

  The present invention relates to an exhaust gas purification apparatus that recovers and purifies exhaust gas such as a diesel engine discharged from an anchored ship from the upper part of the ship chimney.

  In general, exhaust gas generated by a ship's diesel engine, boiler, etc. is discharged into the atmosphere as it is without being treated at all during the anchorage or docking in the waters of the port as well as during the voyage of the ship. And in some ships such as automobile transport ships, the particulates (PM) in the exhaust gas discharged during berths are released to the outside air, and then fall to the outer wall of the car, which is the cargo, and the particulates (PM) Shippers have started to request that particulate matter (PM) in exhaust gas be removed so as not to damage the paint on the outer wall of the automobile due to sulfuric acid components.

  Recently, the environmental effects of particulate matter (PM), NOx, and SOx in the exhaust gas discharged by ships anchored or docked in the harbor waters cannot be ignored. Measures for purifying the exhaust gas discharged from the ship are also required from the environmental viewpoint. In particular, in the area adjacent to the harbor, the current situation is that there is a great concern about the impact of particulates (PM) discharged from ships on local residents.

  For this reason, some ships try to filter out the fine particles (PM) in the exhaust gas with a metal filter or a ceramic filter. The fine particles (PM) in the exhaust gas can be used to filter the metal filter or ceramic. The filter made by clogging in a short time is difficult even for several hours of continuous operation. Further, the present situation is that NOx and SOx in the exhaust gas are exhausted into the atmosphere as they are without taking any measures.

  Further, in order to remove particulate matter (PM) in the exhaust gas, even when an exhaust gas purification device composed of the metal filter or ceramic filter is provided in the ship, the exhaust gas purification device is provided in a limited narrow ship space. That is, even in the case of a new ship with a relatively high degree of freedom in design, there are many restrictions on its installation location and area. In addition, it is very difficult and problematic to change the exhaust gas system of an existing ship already in service and to provide this exhaust gas purifying device.

  Therefore, the present invention suspends an exhaust gas collector for collecting the exhaust gas at the upper part of the chimney of the ship by a crane device provided at a place other than the ship that discharges exhaust gas such as a floating ship and a quay. The exhaust gas is collected and processed at a place other than a ship such as a floating ship or a quay to constitute an exhaust gas recovery and purification device.

  In the present invention, the exhaust gas purifier is installed in a ship that exhausts particulates (PM), NOx, and SOx contained in exhaust gas such as diesel engines and boilers that are discharged from the anchored ship. Even if not, it can be purified economically and effectively. In other words, it is not necessary to provide an exhaust gas purification device for each of the many ships already in service, and a floating ship that can secure a sufficient exhaust gas purification device space instead of a narrow space as in the ship. Since an exhaust gas purification device can be provided at a place other than a ship such as a quay or quay, environmental pollutants such as particulates (PM) and NOx and SOx in the exhaust gas discharged from the ship can be effectively purified.

  Further, according to the present invention, in a ship newly constructed in the future, since it is not necessary to provide an exhaust gas purification device for each ship, the construction cost is reduced. In addition, it can be easily estimated that environmental standards will become stricter in the future, but it is economical because it is not necessary to improve the performance of existing exhaust gas purification devices installed in each ship each time the environmental standards are changed. .

  Hereinafter, the best embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, a piping system of an exhaust gas recovery and purification device is provided with a crane device 3 for suspending an exhaust gas collector 2 on a ship of a floating ship 1.
