Abstract
Description
The present invention relates to an exhaust gas purifying apparatus, and more particularly to an exhaust gas purifying apparatus capable of purifying noxious gas discharged from a large diesel engine such as a ship.
Exhaust gases emitted from chemical processes, semiconductor manufacturing processes or transportation means such as automobiles and ships are not only harmful to human body due to their high toxicity, explosiveness and corrosiveness, but also cause environmental pollution if they are released into the atmosphere . Therefore, the exhaust gas must be purified to reduce the content of harmful components to below the permissible concentration. Thus, only the exhaust gas having undergone the purification process for removing the toxic substances is required to be discharged into the atmosphere.
Methods of treating various harmful exhaust gases include a burning method, a wetting method, and an absorption method.
The combustion method is a method of treating an exhaust gas by decomposing an ignitable gas containing a hydrogen group or the like at a high temperature of about 500 to 800 DEG C in a high-temperature combustion chamber, and the wet method is mainly a method of dissolving a water- And the exhaust system is a system in which the harmful gas which does not ignite or does not dissolve in water is passed through the adsorbent to be purified by physical or chemical adsorption.
Such exhaust gas treatment includes, for example, a scrubbing treatment for removing acid gas or particles from the exhaust gas stream, and the liquid is used to remove fine components or particles contained in the gas.
The cleaning process includes a cylindrical body having an outlet at an upper end thereof, a guide vane installed in the body so as to allow contaminants to flow in contact with the inner circumferential surface of the lower one, a slot plate radially installed in the body, A plurality of cleaning liquid supply devices having an impact plate installed upward and a cleaning liquid jetting unit provided on the impingement plate and spaced apart at regular intervals. At this time, a pump for supplying the cleaning liquid to the demister and the cleaning liquid spraying unit may be installed above the cleaning liquid spraying unit.
In such a conventional scrubber, the exhaust gas rises through between the packings, and the water falls down from the top of the packed material being sprayed. At this time, by filling a large amount of the filler in the cleaning dust collector in order to lengthen the time for the exhaust gas to stay in the washing dust collector, the exhaust gas rises up between the fillers, and the time for the cleaning liquid to come into contact with each other while being lowered becomes longer. In this case, the filler is preferably as large as the surface area, and the droplets of the cleaning liquid falling off the filler are formed as a thin film and flow downward, so that the surface area of meeting the exhaust gas is widened and the amount of the exhaust gas absorbed increases.
However, since the space and the weight occupied by the engine and the related apparatus are large in a large-sized ship, if the space and the weight are reduced, the loading capacity of the ship can be improved. Therefore, there is a demand for research on the structure of an exhaust gas purifying apparatus improved in structure to reduce the volume and weight of the engine system.
The present embodiment provides an exhaust gas purifying apparatus for a ship capable of forcibly passing exhaust gas into a tunnel of water by high-pressure water injection while removing harmful components contained in the exhaust gas and reducing engine noise.
The apparatus for purifying exhaust gas of a ship according to the present embodiment includes a case having a space portion therein and having an opening portion at an upper portion and a lower portion; A base which is coupled to be able to close an opening formed in a lower portion of the case and in which an exhaust gas is supplied to an internal space portion of the case; A guide plate disposed at a space inside the case and spaced apart from the base by a predetermined distance; A collecting pipe having one end coupled to the guide plate and the other end coupled to an upper opening formed on an upper surface of the case and having a plurality of through holes formed in a side surface thereof; A plurality of peripheral spraying tubes disposed on a circumferential surface of the collecting tube and having a plurality of peripheral spraying nozzles formed on the surface facing the collecting tube; A central spray tube disposed at the center of the collection tube and having a plurality of central spray nozzles formed to face the inner surface of the collection tube; And a screw-shaped guide plate having one end connected to the upper portion of the case and the other end connected to the upper side of the guide plate to guide the exhaust gas flowing through the input pipe in a spiral shape.
A certain level of water can be stored in the space formed through the coupling of the case and the base.
The guide plate may have an inclined surface on a surface facing the input tube.
The guide plate may include a plurality of first and second water pipes for collecting and discharging water sprayed through the center and peripheral spray pipes.
The first drain pipe may be formed to have a larger diameter than the second drain pipe.
The second water pipe is disposed in an inner space of the collecting pipe, and is capable of collecting water sprayed through the central spray pipe.
The collecting pipe may be formed in a cylindrical shape and may be formed so as to have a plurality of through holes on the side wall so as to have a predetermined diameter and an interval.
The lower surface of the collecting tube may be engaged with the guide plate, and the upper surface may be engaged with the upper surface of the case.
The guide plate may have at least one through hole formed therethrough, and the diameter of the through hole disposed at the lower side may be larger than the diameter of the through hole disposed at the upper side.
According to the present embodiment as described above, it is possible to reduce the space and weight occupied by a large-sized diesel engine and an associated apparatus such as a ship or an offshore plant.
In addition, because of the size of the conventional engine, it is possible to apply to small ships as well as mid- to large-sized vessels that are installed or not installed at a smaller scale than the required capacity, so that the emission of harmful substances among various exhaust gases of various ships can be blocked. .
