Description

Technical Field

[0001] The present invention relates to the technical field of engine exhaust purification, and in particular to an integrated system for desulfurization and decarbonization of ship exhaust gas. Background Art

[0002] Marine diesel engines generate exhaust gas, mainly including carbon dioxide, carbon monoxide, nitrogen oxides, particulate matter and sulfur oxides. In order to reduce the impact of these exhaust gases on the environment, the integrated system for desulfurization, denitrification and decarbonization of marine exhaust gas disclosed in publication number CN106968760B treats the exhaust gas generated by marine diesel engines through a heat exchanger, a desulfurization scrubber, a carbon dioxide membrane separator, a carbon dioxide storage tank and an intake valve group. In particular, for the emission of sulfur oxides, the scrubber absorbs and neutralizes the harmful components in the exhaust gas by spraying liquid (such as seawater or chemical solution), thereby reducing the emission level.

[0003] The desulfurization washing tower, such as the horizontal desulfurization washing tower for ship exhaust gas disclosed in the prior art with publication number CN112983600A, desulfurizes by allowing the flue gas to be fully contacted and mixed with limestone powder and water into slurry in multiple layers for multiple times, so that the flue gas can be fully contacted with the slurry during rapid circulation. However, the dihydrate gypsum formed by desulfurization crystallization may have a certain degree of adhesion and adhere to the surface of the washing plate or the filler, which cannot be effectively removed by shaking alone. In addition, the concentration, particle size and properties of the slurry will affect its fluidity in the tower. Slurry with higher concentration is more likely to cause blockage. In addition, the multiple washing plates arranged in the device make the flow path complicated, and simple shaking may not be able to act evenly on all areas. In this way, when the exhaust gas is discharged between the washing plates for desulfurization, the exhaust gas is likely to cause poor flow and cannot be normally contacted and mixed with the slurry made of limestone powder and water. Not only can the exhaust gas not circulate normally, but it may also cause serious malfunctions in the operation of the diesel engine. Summary of the invention

[0018] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0019] First, the dissolved exhaust gas will flow upward through the wind collecting plate and the air outlet plate, and in the process it will drive the fan blades and the rotating rod to rotate. The Hall speed sensor will detect the rotation time of the fan blades and the rotating rod. After the lime water and exhaust gas are dissolved in the filler for a long time, the desulfurization crystallization forms dihydrate gypsum, which may adhere strongly to the surface of the filler and cause blockage, preventing the exhaust gas from flowing normally and the fan blades and the rotating rod from rotating. The Hall speed sensor will detect the rotation time of the fan blades and the rotating rod to determine whether there is a blockage, and drive the water pressure plate to continuously squeeze the lime water inside the water tank, allowing the lime water to flow back to the tower body through the water flow box to backwash the filler, so as to avoid blockage of the filler and prevent the exhaust gas from flowing normally.

[0020] Secondly, by setting the exhaust ring pipe, the sliding sheet and the guide rod driven to rotate can contact the outlet plug in turn, so that the outlet groove is connected with the outside and the exhaust gas is discharged outwardly. The exhausted exhaust gas is evenly sprayed into the filler arranged inside the washing tower through the outlet groove, so as to avoid uneven use area of ​​the filler. Through the setting of the rotating disk, when the exhaust gas enters the inside of the tower body, the rotating disk rotates to stagger the first through hole and the second through hole, so that the gas pressure inside the tower body is increased and dissolved with lime water inside the filler, and the lime water continues to be above the water collecting plate. When the rotating disk rotates to make the first through hole overlap with the second through hole, the lime water accumulated above the water collecting plate will flow in the first through hole and the second through hole, and the exhaust gas with increased air pressure will flow upward through the first through hole and the second through hole, and dissolve with the lime water again while flowing, so as to increase the desulfurization effect of the exhaust gas.

[0021] Thirdly, two alternately used particulate filters are set up to filter the exhaust gas discharged by the diesel engine. When one of them is in use, the other one can be connected to the air intake joint through an external jet device to back-blow the particulate filter. At the same time, the heating element can heat the particulate matter to the auto-ignition temperature to heat and regenerate the particulate filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The working principle of the present invention is as follows:

[0053] By discharging lime water into the water tank 201, the lime water will flow into the tower body 231, and the lime water will be discharged to a height that submerges the exhaust ring pipe 222, and the exhaust gas will flow from the air inlet pipe 221 to the inside of the exhaust ring pipe 222. By opening the telescopic member 211, the telescopic end of the telescopic member 211 will drive the lifting plate 214 to lift and slide on the inner wall of the sleeve 213, and the lifting plate 214 will drive the first screw 218 to descend together during the descent process, and the descending first screw 218 will mesh with the rotating ring 220 to rotate, so that the first screw 218 will also rotate during the process of being driven to descend, and at this time, the rotating and lifting first screw 218 will mesh with the linkage ring 223, driving the linkage ring 223 to rotate on the upper end surface of the water collecting plate 206 (the first screw 218 adopts a non-self-locking thread ), the rotating linkage ring 223 will drive the sliding piece 225 and the guide rod 226 to rotate together inside the exhaust ring pipe 222 through the connecting rod 224, and the guide rod 226 will contact the outlet plug 229 during the rotation and drive the outlet plug 229 to compress the first spring 228 and slide upward, so that the outlet groove is connected with the outside, and the exhaust gas entering the exhaust ring pipe 222 through the intake pipe 221 will be evenly sprayed into the filler 205 set inside the tower body 231 through the outlet groove, and a plurality of outlet plugs 229 are slidably installed in the exhaust ring pipe 222. When the sliding piece 225 and the guide rod 226 are driven to rotate, they will continuously contact each outlet plug 229, so that the exhaust gas can be evenly sprayed into the filler 205 set inside the tower body 231 through the outlet groove, avoiding uneven use of the filler 205 area;

[0054] The exhaust gas sprayed into the tower body 231 will enter the interior of the filler 205. By setting a water pump, the lime water in the water tank 201 can be pumped into the water spray head 203 through the water injection pipe 202, and then sprayed from the water spray head 203 to the upper end of the diverter plate 204. The lime water will flow downward evenly from the first through hole (the diverter plate 204 is set to a cone, and the lime water will flow evenly into the first through hole through the cone during the flow process), and then flow into the filler 205 through the second through hole. Inside the filler 205, the lime water converts the sulfur dioxide in the flue gas into non-volatile calcium sulfite through a chemical reaction, thereby achieving the purpose of desulfurization. Subsequently, the lime water flows back to the bottom end of the tower body 231 under the action of gravity and gathers. In this process, the lifting plate 214 will drive the linkage frame 215 to lift and lower when it is driven to lift and lower. When the linkage frame 215 is lifted and lowered, the lime water will be lifted and lowered. During the lowering process, the upper end of the linkage frame 215 will be slidably connected with the slide groove provided by the cam 232, and drive the cam 232 to rotate, and the rotating cam 232 will drive the rotating disk 216 to rotate together, and the rotating rotating disk 216 will make the second through hole staggered and overlapped with the first through hole. When the second through hole is staggered with the first through hole, the lime water sprayed by the water spray head 203 will gather above the diverter plate 204, and the exhaust gas will gather on the lower end surface of the rotating disk 216 and increase the air pressure, so that the exhaust gas can be retained in the filler 205 for a longer time to dissolve with the lime water, thereby improving the efficiency of the exhaust gas dissolving in the lime water. When the second through hole coincides with the first through hole, the lime water gathered above the diverter plate 204 will flow down through the first through hole and the second through hole, and the exhaust gas accumulated with a certain air pressure will be sprayed upward through the first through hole and the second through hole, and will be dissolved with the lime water again while being sprayed.

[0055] It should be noted that, during the lifting process of the first screw 218, the stirring rod 219 will be driven to lift and lower inside the water box 207, so as to stir the dissolved lime water to prevent the lime water from solidifying or settling at the inner bottom end of the tower body 231;

[0056] The waste gas dissolved in lime water can flow upward through the first through hole and the second through hole, pass through the wind collecting plate 208 and the air outlet plate 209, and be discharged outward through the air outlet. In this process, the waste gas will drive the fan blades 308 and the rotating rod 306 to rotate, and the waste gas intermittently flows upward through the first through hole and the second through hole, and drives the fan blades 308 and the rotating rod 306 to rotate. The rotation speed of the fan blades 308 and the rotating rod 306 is detected by the set Hall speed sensor 307. The Hall speed sensor 307 will send a signal to the controller in real time. When the fan blades 308 and the rotating rod 306 stop rotating for more than the set time, the controller will determine that the waste gas is not flowing smoothly inside the tower body 231, and the controller will control the opening of the first rotating drive member 302. The first rotating drive member 302 will drive the threaded sleeve 303 to rotate. The threaded sleeve 303 will drive the second screw 304 to rotate and shrink inside the threaded sleeve 303. The rotating and shrinking second screw 304 will drive the water pressure plate 305 to slide inside the water tank 201, and squeeze the lime water inside the water tank 201 into the inside of the tower body 231 through the water flow box 207, so that the lime water enters the inside of the water collecting plate 206 through the pipeline, and then sprays upward through the inlet and outlet holes 212 to backwash the filler 205. The first rotating drive member 302 will maintain a periodic (the duration can be set by the time of the pre-flushing experiment test) forward and reverse rotation, so as to drive the water pressure plate 305 to continuously squeeze the lime water inside the water tank 201, so that the lime water can flush the filler 205, and prevent the solid particles in the lime water from being precipitated and gathered on the filler, causing blockage and affecting the flow of exhaust gas;

[0057] During the rotation of the threaded sleeve 303, the first transmission rod 309 is driven to rotate, and the rotating first transmission rod 309 drives the second transmission rod 310 to rotate through the bevel gear pair, and the rotating second transmission rod 310 drives the straight rod 312 and the arc extrusion rod 313 to rotate on the upper end surface of the filler 205. When the lime water backwashes the filler 205, the lime water drives the solid particles accumulated in the filler 205 to spray upward together, and the rotating straight rod 312 pushes the solid particles and the lime water. During the rotation of the arc extrusion rod 313, it contacts the top block 320 and drives the sealing slider 319 and the fixing plate 317 to stretch the second spring 318, so that the sealing slider 319 slides in the sliding column 316, and the straight rod 312 pushes the solid particles and the lime water into the drain pipe 314, flows into the water filter box 321 through the water outlet trough 315, and then flows back to the inside of the water tank 201 after being filtered by the filter cotton 322;

[0058] After the diesel engine discharges exhaust gas, it can be discharged into the particulate trap 407 through a pipeline connected to the exhaust pipe 414. By opening the second rotating drive member 404, the rotating shaft 405 drives the circular frame 406 to rotate, so that the two particulate traps 407 are replaced in turn (the time is customized by the controller, and when the customized time is checked, the controller sends a signal to drive the second rotating drive member 404 to rotate and replace the two particulate traps 407). After one of the particulate traps 407 is saturated with adsorption, it can be replaced by another one for filtering. When filtering, the magnetic ring 410 can stretch the bellows 409 and adsorb it together with the iron plate 412, so that the flue gas is transported to the inside of the particulate trap 407 through the bellows 409 for filtration. By connecting to the air intake joint 413 through an external jet device, the saturated particulate trap 407 can be backblown, and the set heating element 408 can heat the particulate matter to reach the auto-ignition temperature to heat and regenerate the particulate trap 407.
