Description

Technical Field

[0001] The present invention relates to the technical field of ship desulfurization, and in particular to a ship desulfurization treatment device. Background Art

[0002] The power units used by transport ships are primarily main engines that burn heavy diesel fuel, emitting large amounts of exhaust gas during navigation. Currently, desulfurization equipment is commonly used to desulfurize ship exhaust gases. In existing technologies, desulfurization towers, serving as desulfurization equipment for ship systems, desulfurize by spraying seawater. The seawater is atomized through a nozzle, forming small droplets that come into contact with the ship's exhaust, spraying and desulfurizing the exhaust. However, most existing ship desulfurization treatment devices typically require manual operation to control the opening and closing of the exhaust duct and the start and stop of the spray system, which can easily pose safety hazards due to improper operation. For example, if there is insufficient spray liquid, the exhaust duct may be mistakenly opened, allowing the ship's exhaust gas to enter the desulfurization tower, resulting in the direct discharge of untreated exhaust gas. Alternatively, when cleaning and maintaining the desulfurization tower, such as oil, scale, and particulate matter left in the ship's exhaust gas, the exhaust duct may be mistakenly opened, allowing the ship's exhaust gas to enter the desulfurization tower, affecting maintenance efficiency. Summary of the Invention

[0008] Preferably, the outer wall of the buoyancy ring is in contact with the inner wall of the water storage chamber, and the open end surface of the water inlet pipe and the open end surface of the water extraction pipe are both in contact with the inner wall of the water storage chamber.

[0009] Preferably, the buoyancy ring and the recovery container are integrally formed, the buoyancy ring, the recovery container and the opening and closing plate are all made of plastic, and a counterweight ring is embedded in the bottom surface of the opening and closing plate.

[0010] Preferably, a square guide ring is fixedly connected to the inner wall of the filter chamber, and the inner wall of the guide ring is formed with a guide surface inclined toward the lifting plate. The inner wall of the guide ring and the outer wall of the lifting plate are in contact with each other, and the lower side of the guide surface is located above the inner end of the interface pipe.

[0011] Preferably, the lower part of the smoke exhaust pipe is connected to a necking section, which is in the shape of an inverted funnel. A connecting ring is provided on the edge of the lower opening of the necking section. The top opening of the desulfurization tower is provided, and the connecting ring is inserted into the top opening of the desulfurization tower.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The observation cover allows staff to observe the relative position of the sealing plate and the interface pipe, so that staff can start and stop the running water pump or the storage water pump according to the observation situation. The staff starts the running water pump to inject spray liquid into the water storage chamber through the water inlet pipe, and uses the buoyancy ring to float the recovery container to the liquid surface in the water storage chamber. The recovery container can change its position with the liquid level in the water storage chamber. At the same time, the lifting plate also changes its position with the buoyancy ring. The lifting plate drives the sealing plate to move up and down, and the mechanical linkage of the liquid buoyancy in the water storage chamber is used to realize the automatic opening and closing of the interface pipe, thereby avoiding waste gas pollution and safety hazards caused by improper manual operation, and improving the operation safety and maintenance efficiency of the desulfurization treatment device.

[0015] 2. The corresponding interface pipe is connected to the smoke inlet pipe to allow the ship's exhaust gas to enter the interior of the desulfurization tower. The ship's exhaust gas rises and passes through the filter chamber and the spray chamber in turn. The water pump is operated to transport the spray liquid in the water storage chamber to the spray pipe and spray it onto the filtered ship's exhaust gas through each spray head, achieving the purpose of washing and absorbing sulfur dioxide in the ship's exhaust gas, effectively improving the efficiency and effect of ship exhaust gas treatment.

[0016] 3. After the spray liquid sprayed by each spray head is sprayed and desulfurized, the spray liquid is collected in the recovery container so that the spray liquid in the recovery container has more sufficient reaction time with the sulfur oxides in the ship's exhaust gas. As the spray liquid in the recovery container is collected, the weight of the recovery container increases, and the recovery container has a tendency to move downward, so that the buoyancy ring squeezes the spray liquid in the water storage chamber, thereby increasing the static pressure of the liquid. The bottom surface of the buoyancy ring is close to the liquid surface of the spray liquid in the water storage chamber, which can suppress the liquid level fluctuation caused by gravity flow and avoid the formation of vortex or bubbles entering the pumping pipe. Local air resistance is formed to ensure that the running water pump stably and continuously transports the spray liquid in the water storage chamber to the spray pipe. The recovery container moves down by utilizing the drop of the liquid level in the water storage chamber to drive the buoyancy ring and the lifting plate to drop until the sealing plate is inserted into the slot. The sealing plate closes the inner end opening of the interface pipe, and the top surface of the recovery pipe abuts against the opening and closing plate to separate the opening and closing plate relative to the recovery container, thereby opening the liquid outlet opening. The spray liquid in the recovery container passes through the liquid outlet opening and the drain hole into the drain pipe to be discharged from the desulfurization tower to wait for spray desulfurization operation or spray cleaning operation.

[0017] 4. When the recovery container moves downward and the blocking plate closes the opening of the interface pipe, the bottom surface of the avoidance ring abuts against the bottom inner wall of the water storage chamber, ensuring that the water inlet pipe and the water extraction pipe are both located below the buoyancy ring; When the interface pipe is closed, the staff starts the storage water pump and shuts down the running water pump to raise the liquid level in the water storage chamber, and then opens the interface pipe to prepare for the subsequent spray desulfurization operation. The interface pipe is opened only when there is sufficient spray liquid in the water storage chamber, and the ship's exhaust gas enters the desulfurization tower for spray desulfurization operation, preventing the direct discharge of untreated exhaust gas. Alternatively, when the interface pipe is closed, the staff starts the storage water pump and the operating water pump to perform spray cleaning operations on the inside of the desulfurization tower, and discharges the spray liquid after spray cleaning from the inside of the desulfurization tower by opening the recovery container with the liquid outlet. The desulfurization treatment device can switch to spray desulfurization operation or spray cleaning operation according to demand. It is flexible in operation and has good applicability, which improves the staff's usage experience. BRIEF DESCRIPTION OF THE DRAWINGS

The interior of the desulfurization tower 1 includes a spray chamber 101, a filter chamber 102, a water storage chamber 103 and a recovery chamber 104 arranged in sequence from top to bottom. The top opening of the desulfurization tower 1 is set, and the top opening of the desulfurization tower 1 is detachably connected to a smoke exhaust pipe 4, and the smoke exhaust pipe 4 is communicated with the spray chamber 101.

[0022] The lower part of the smoke exhaust pipe 4 is connected to a necking section 401, which is in the shape of an inverted funnel. A connecting ring 402 is provided on the edge of the lower opening of the necking section 401. The connecting ring 402 is inserted into the upper opening of the desulfurization tower 1. A connecting rod 403 is provided on the inner wall of the connecting ring 402. Four impellers 404 are sleeved on the connecting rod 403.

[0023] Two spray pipes 105 are horizontally arranged in the spray chamber 101 at intervals. Several spray heads 106 are arranged at intervals below the spray pipes 105. The spray heads 106 are conventional and will not be described in detail here.

[0024] Both the operating water pump 2 and the storage water pump 3 are electric water pumps. Electric water pumps are conventional and will not be described in detail here. The storage water pump 3 is equipped with an inlet pipe 301 connected to the bottom of the water storage chamber 103 to transport the spray liquid from the outside into the water storage chamber 103. The operating water pump 2 is equipped with a drain pipe 201 connected to the spray pipe 105 and a pump pipe 202 connected to the bottom of the water storage chamber 103 to transport the spray liquid from the water storage chamber 103 into the spray pipe 105 and spray it into the spray chamber 101 through the spray heads 106.

[0025] Two interface pipes 5 arranged opposite to each other are connected at the bottom of the filter chamber 102. The outer ends of the two interface pipes 5 extend to the outside of the desulfurization tower 1, and the outer ends of the two interface pipes 5 are respectively provided with an observation cover 6 and a smoke inlet pipe 7. The smoke inlet pipe 7 is provided with a smoke inlet valve 701. The smoke inlet valve 701 is a valve. The valve is a prior art and will not be described in detail here. The smoke inlet valve 701 is used to control the opening and closing of the smoke inlet pipe 7. The observation cover 6 is made of tempered borosilicate glass. The observation cover 6 can be fixed to the outer end of the corresponding interface pipe 5 by screw-in connection or threaded connection to close the opening of the outer end of the interface pipe 5. The observation cover 6 can be used for staff to observe the relative position of the sealing plate 1502 and the interface pipe 5, so that the staff can operate the desulfurization treatment device according to the observed situation. The smoke inlet valve 701 is a stop valve. The stop valve is a prior art and will not be described in detail here.

[0026] refer to Figure 2 、 Figure 3 The recovery chamber 104 is located at the center of the water storage chamber 103. A recovery container 9 with an upward opening is slidably connected to the recovery chamber 104. The height of the recovery container 9 is greater than that of the recovery chamber 104. A buoyancy ring 901 is provided at the edge of the opening of the recovery container 9. The buoyancy ring 901 is a hollow annular structure. A lifting plate 15 is vertically provided at the position of the buoyancy ring 901 relative to the interface tube 5. The lifting plate 15 is provided with a lifting groove 1501 extending along its height direction. The inner end of the interface tube 5 passes through the lifting groove 1501. The sliding connection between the inner end of the interface tube 5 and the lifting groove 1501 guides the lifting plate 15 to move up and down relative to the filter tank. A slot 501 is provided above the inner end of the interface tube 5. A sealing plate 1502 is provided on the upper portion of the lifting groove 1501. The sealing plate 1502 is inserted into the slot 501.

[0027] refer to Figure 2 、 Figure 4 、 Figure 5The bottom inner wall of the recovery container 9 is provided with a liquid outlet opening 903, and the liquid outlet opening 903 is detachably provided with an opening and closing plate 12, which is used to close the liquid outlet opening 903. The buoyancy ring 901 is integrally formed with the recovery container 9. The buoyancy ring 901, the recovery container 9, and the opening and closing plate 12 are all made of plastic, which can be polyvinyl chloride or polypropylene.

[0028] The inner wall of the liquid outlet opening 903 is an inner conical surface, the opening and closing plate 12 is circular, and the circumferential outer wall of the opening and closing plate 12 is an outer conical surface. The circumferential outer wall of the opening and closing plate 12 is in contact with the inner wall of the liquid outlet opening 903. A counterweight ring 1201 is embedded in the bottom surface of the opening and closing plate 12, and the counterweight ring 1201 is coaxially arranged with the opening and closing plate 12. The counterweight ring 1201 is used to balance the opening and closing plate 12 to ensure that the opening and closing plate 12 falls stably to close the liquid outlet opening 903. The opening and closing plate 12 is cooperated with the counterweight ring 1201 so that the opening and closing plate 12 can automatically reset to the position aligned with the liquid outlet opening 903 after it is separated from the liquid outlet opening 903, which helps to maintain a good fit between the opening and closing plate 12 and the liquid outlet opening 903 and maintain the sealing performance. Moreover, after multiple opening and closing operations, the position of the opening and closing plate 12 can be kept relatively stable without serious dislocation that affects the sealing and normal use.

[0029] A filter assembly 8 is disposed within the filter chamber 102, covering the flow area of ​​the filter chamber 102. The filter assembly 8 comprises a filter plate 81 and two docking portions 82 symmetrically disposed on the filter plate 81. The filter plate 81 and the filter chamber 102 are adapted in shape. The filter plate 81 is a multi-layer sintered metal mesh, which is conventional and will not be described in detail here. The upper portion of the docking portion 82 extends to the top surface of the filter plate 81 and is provided with a hanging ring 802. The lower portion of the docking portion 82 extends to the bottom surface of the filter plate 81 and is provided with a docking slot 801 for the lifting plate 15 to engage, allowing the filter plate 81 to be suspended and aligned on the two lifting plates 15.

[0030] A recovery ring 13 and a recovery pipe 14 are coaxially arranged at the bottom of the recovery chamber 104. The recovery ring 13 is adapted to the opening and closing plate 12. The outer diameter of the recovery ring 13 is smaller than the inner diameter of the liquid outlet opening 903. The recovery ring 13 is provided with two symmetrically arranged drainage holes 1301. The recovery pipe 14 is connected and arranged at the bottom of the recovery chamber 104, and the recovery pipe 14 extends to the outside of the desulfurization tower 1.

[0031] When the desulfurization treatment device is in use, the staff starts the water pump 2 to inject spray liquid into the water storage chamber 103 through the water inlet pipe 301, and uses the buoyancy ring 901 to float the recovery container 9 to the liquid surface in the water storage chamber 103, so that the recovery container 9 can move up with the rise of the liquid level in the water storage chamber 103, and the recovery container 9 drives the two lifting plates 15 to move up synchronously, so that the sealing plate 1502 moves up relative to the interface pipe 5 and is staggered, thereby opening the interface pipe 5. The staff can check the position between the corresponding sealing plate 1502 and the interface pipe 5 through the observation cover 6 to determine whether the spray liquid in the water storage chamber 103 is full. When the spray liquid in the water storage chamber 103 is full, the sealing plate 1502 is completely separated from the slot 501 of the interface pipe 5, so that the interface pipe 5 is fully opened. At this time, the staff can turn off the storage water pump 3, start the water pump 2, open the smoke inlet valve 701, and perform spray desulfurization operations on the ship's exhaust gas.

[0032] The corresponding interface pipe 5 is connected to the smoke inlet pipe 7 to allow the ship's exhaust gas to enter the interior of the desulfurization tower 1. The ship's exhaust gas is discharged from the interface pipe 5 and rises and passes through the filter chamber 102 and the spray chamber 101 in turn. The filter component 8 in the filter chamber 102 filters the ship's exhaust gas, which can effectively intercept particulate matter in the ship's exhaust gas and reduce dust pollution. The water pump 2 is operated to transport the spray liquid in the water storage chamber 103 to the spray pipe 105 and spray it onto the filtered ship's exhaust gas through each spray head 106, so as to achieve the purpose of washing and absorbing sulfur dioxide in the ship's exhaust gas, effectively improving the efficiency and effect of the ship's exhaust gas treatment. The desulfurized ship's exhaust gas drives each impeller 404 to rotate circumferentially around the connecting rod 403 when it rises. When the impeller 404 rotates, its blades will produce a mechanical driving effect on the surrounding airflow, so that the desulfurized ship's exhaust gas is more evenly distributed in the necking section 401 and discharged from the smoke exhaust pipe 4. After discharging the desulfurization tower 1, the ship's exhaust gas can be better mixed with the surrounding atmospheric environment.

[0033] The outer wall of the recovery container 9 and the inner wall of the recovery chamber 104 are in contact with each other. Preferably, the inner wall of the recovery chamber 104 can be coated with a ceramic coating or a polytetrafluoroethylene coating. The contact and seal between the recovery container 9 and the recovery chamber 104 prevent the spray liquid in the water storage chamber 103 from leaking into the recovery chamber 104. The outer wall of the buoyancy ring 901 and the inner wall of the water storage chamber 103 are in contact with each other. The contact and seal between the buoyancy ring 901 and the water storage chamber 103 prevent the spray liquid in the water storage chamber 103 from overflowing the buoyancy ring 901 and entering the filter chamber 102, and prevent the spray liquid sprayed in the spray chamber 101 from entering the water storage chamber 103.

[0034] A guide ring 108 is fixedly connected to the inner wall of the filter chamber 102. The inner wall of the guide ring 108 is formed with a guide surface 109 that is inclined toward the lifting plate 15. The inner wall of the guide ring 108 and the outer wall of the lifting plate 15 intersect and cooperate to limit and guide the lifting and lowering movement of the lifting plate 15. The lower side of the guide surface 109 is located above the inner end of the interface tube 5, and is used to guide the spray liquid sprayed within the spray chamber 101 along the guide surface 109 into the space between the two lifting plates 15. The inner wall of the opening of the buoyancy ring 901 is an inner conical surface, and the inner wall of the larger diameter side of the opening of the buoyancy ring 901 is located below the inner end of the interface tube 5. The top surface of the buoyancy ring 901 abuts against the lower inner end of the interface tube 5, guiding the spray liquid to be collected in the recovery container 9.

[0035] After the spray liquid sprayed by each spray head 106 is sprayed and desulfurized, the spray liquid is collected in the recovery container 9, so that the spray liquid in the recovery container 9 has more sufficient reaction time with the sulfur oxides in the ship's exhaust gas. As the spray liquid in the recovery container 9 is collected, the weight of the recovery container 9 increases, and the recovery container 9 has a tendency to move downward, so that the buoyancy ring 901 squeezes the spray liquid in the water storage chamber 103, thereby increasing the static pressure of the liquid. The bottom surface of the buoyancy ring 901 is close to the liquid surface of the spray liquid in the water storage chamber 103, which can inhibit the liquid from flowing due to gravity. The liquid level fluctuates to prevent the formation of vortices or bubbles entering the pumping pipe 202 and causing local air blockage, ensuring that the running water pump 2 stably and continuously delivers the spray liquid in the water storage chamber 103 to the spray pipe 105. As the liquid level in the water storage chamber 103 drops, the recovery container 9 moves downward, driving the buoyancy ring 901 and the lifting plate 15 to descend, and the blocking plate 1502 moves downward accordingly until the blocking plate 1502 is inserted into the slot 501. The blocking plate 1502 seals the inner end opening of the interface pipe 5, preventing the ship's exhaust gas from entering the desulfurization tower 1 through the interface pipe 5. At this time, the top surface of the recovery pipe 14 abuts the bottom surface of the opening and closing plate 12, separating the opening and closing plate 12 from the recovery container 9, thereby opening the liquid outlet opening 903. The spray liquid in the recovery container 9 passes through the liquid outlet opening 903 and the drain hole 1301 into the drain pipe 1103 and is discharged from the desulfurization tower 1 to be sprayed for desulfurization or spray cleaning operations.

[0036] The outer wall of the recovery container 9 is provided with an avoidance ring 902, which is coaxially arranged with the buoyancy ring 901. The avoidance ring 902 is located below the buoyancy ring 901. When the recovery container 9 moves down into place, the sealing plate 1502 closes the opening of the interface pipe 5, and the bottom surface of the avoidance ring 902 abuts against the bottom inner wall of the water storage chamber 103 to separate the buoyancy ring 901 from the bottom inner wall of the water storage chamber 103, so that the buoyancy ring 901 avoids the water suction pipe 202 and the water inlet pipe 301, ensuring that the water inlet pipe 301 and the water suction pipe 202 are both located below the buoyancy ring 901, preventing the buoyancy ring 901 from interfering with the operation of the water inlet pipe 301 and the water suction pipe 202.

[0037] When the interface pipe 5 is closed, the staff starts the storage water pump 3 and shuts down the running water pump 2 to raise the liquid level in the water storage chamber 103, and then opens the interface pipe 5 to prepare for the subsequent spray desulfurization operation. The desulfurization treatment device opens the interface pipe 5 only when there is enough spray liquid in the water storage chamber 103, and the ship's exhaust gas enters the desulfurization tower 1 for spray desulfurization operation to prevent the direct discharge of untreated exhaust gas.

[0038] Alternatively, when the interface pipe 5 is closed, the staff starts the storage water pump 3 and the operating water pump 2 to perform spray cleaning operations on the interior of the desulfurization tower 1, and discharges the spray liquid after spray cleaning from the interior of the desulfurization tower 1 by opening the recovery container 9 with the liquid outlet opening 903. The desulfurization treatment device can switch to spray desulfurization operation or spray cleaning operation according to demand. It is flexible in operation and has good applicability, which improves the staff's usage experience.

[0039] When the desulfurization treatment device is in use, the recovery container 9 can change its position according to the liquid level in the water storage chamber 103. At the same time, the lifting plate 15 also changes its position according to the buoyancy ring 901. The lifting plate 15 drives the sealing plate 1502 to move up and down, and utilizes the mechanical linkage of the liquid buoyancy in the water storage chamber 103 to realize the automatic opening and closing of the interface pipe 5, thereby avoiding waste gas pollution and safety hazards caused by improper manual operation, and improving the operation safety and maintenance efficiency of the desulfurization treatment device.

[0040] Preferably, a guide slope 1302 is formed on the upper part of the inner wall of the drainage hole 1301, and the guide slope 1302 is inclined toward the recovery chamber 104, and the guide slope 1302 extends to the opening edge of the drainage hole 1301. The guide slope 1302 cooperates with the circumferential outer wall of the opening and closing plate 12 to make the discharge of the spray liquid in the recovery container 9 smoother.

[0041] A funnel-shaped discharge chamber 107 is formed on the bottom inner cavity wall of the recovery chamber 104 relative to the recovery ring 13. The upper opening of the discharge chamber 107 is an opening with a larger diameter, and the lower opening of the discharge chamber 107 is an opening with a smaller diameter. The lower opening of the discharge chamber 107 is interconnected with the upper end opening of the recovery pipe 14, and the upper opening of the discharge chamber 107 is respectively interconnected with each drainage hole 1301. The funnel-shaped discharge chamber 107 guides the liquid flow direction, accelerates the discharge speed of the spray liquid in the collection container, and the inner wall of the discharge chamber 107 is adapted to the inner wall of the liquid outlet opening 903, which can ensure that the spray liquid flows smoothly during the discharge process and ensures the stability of the discharge.

[0042] Preferably, the top surface of the opening and closing plate 12 is an upwardly curved spherical surface, which facilitates the convergence and flow of liquid and reduces the residue of the spray liquid on the opening and closing plate 12 .
