Description

Technical Field

[0001] The invention belongs to the technical field of seawater desalination, in particular to a boiler flue gas seawater desalination device and a use method thereof. Background Art

[0002] Marine desalination is the process of converting seawater into fresh water on a ship at sea using desalination technology. This technology is of great significance in the history of navigation, especially for long-distance voyages or when the ship is docked in areas without fresh water resources. With the ocean occupying the vast majority of the earth's surface, fresh water resources are relatively scarce and only account for a small part of the available water resources. Especially in areas far from land or where resources are scarce, such as long-distance voyages, ocean voyages or remote islands, obtaining fresh water becomes particularly difficult.

[0003] When the boiler inside the hull is working, a large amount of waste smoke and exhaust gas will be generated. These waste smoke and exhaust gas contain a large amount of heat energy. At the same time, these gases are toxic and are usually discharged directly into the external environment and cannot be directly utilized, thus causing energy loss. If the heat energy can be effectively utilized to produce ship fresh water resources, the energy consumed in producing fresh water can be effectively reduced, achieving energy-saving effects. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a boiler flue gas seawater desalination device, comprising a surrounding component, a drainage component is arranged at the bottom of the surrounding component, and a pressurizing component is arranged at the top of the surrounding component;

[0006] The distillation component includes a surround guide rail, which and the heat-resistant coil are both made of heat-resistant elastic rubber, can be twisted with the bending deformation of the heat-resistant coil, and directly fit with the outer surface of the boiler, the top of the inner cavity of the surround guide rail is evenly provided with bending transfer tubes through the through opening, the bottom of the inner wall of the bending transfer tube is fixedly connected with an injection end head, and the end of the inner wall of the bending transfer tube away from the surround guide rail is fixedly connected with a conical inner sleeve, the conical inner sleeve is an outwardly expanding structure, which prevents external liquid water from flowing back into the interior of the bending transfer tube without affecting the discharge of water vapor.

[0007] Furthermore, the drainage component includes a water storage bottom belt, which stores condensed liquid water. Vertical drainage pipes are evenly arranged on the top of the inner cavity of the water storage bottom belt. Condensation pipes are evenly arranged on the side of the inner cavity of the vertical drainage pipe away from the bent transfer pipe. One end of the condensation pipe extends to the outside of the vertical drainage pipe for heat dissipation. Water vapor that contacts the condensation pipe will quickly release heat and liquefy. After absorbing heat, the condensation pipe will quickly dissipate heat through the end extending to the outside of the vertical drainage pipe. Both ends of the water storage bottom belt are fixedly connected with an oblique drainage shell.

[0008] Furthermore, the number of the surrounding guide rails is three, the outer surface of the surrounding guide rails is fixedly connected to the inner wall of the heat-resistant coil, the top of the bent adapter tube is plugged into the inner cavity of the vertical drainage tube through a docking socket, and the inner wall of the water storage bottom belt is fixedly connected to the bottom of the outer surface of the heat-resistant coil. The rear end of the water injection pipe is fixedly connected to one end of the surrounding guide rail, the number of the water injection pipes is six, the outer surface of the limit card belt is rotatably connected to the outer surface of the heat-resistant coil, and the bottom end of the vertical drainage pipe extends to the inside of the water storage bottom belt.

[0009] Furthermore, the pressurizing component includes a closed top ring, a control push plate is fixedly connected to one side of the inner wall of the closed top ring close to the limit card belt, sliding push blocks are symmetrically arranged on both sides of the inner wall of the control push plate, and the sliding push blocks completely fill and seal the inner wall of the closed top ring, and cold air pressurizers are symmetrically arranged on both sides of the outer surface of the closed top ring, and the cold air pressurizer can pressurize the inside of the closed top ring and cool down the pressurized gas through the internal air conditioner, and one-way nozzles are evenly arranged at the bottom of the inner cavity of the closed top ring. The lower surface of the closed top ring is plugged into the top end of the vertical drainage pipe, the air jet of the cold air pressurizer extends to the inside of the closed top ring, and the outer surface of the cold air pressurizer is fixedly connected to the outer surface of the closed top ring, and the outer surface of the sliding push block is slidably connected to the inner wall of the closed top ring.

[0010] Furthermore, the one-way nozzle includes a sliding sleeve, a compression washer is sleeved on the upper part of the outer surface of the sliding sleeve, drainage grooves are evenly opened on the upper part of the inner cavity of the sliding sleeve, a pressure-bearing sleeve is fixedly connected to the bottom of the inner wall of the sliding sleeve, and an isolation rubber pad is fixedly connected to the top of the output shaft of the pressure-bearing sleeve. The bottom end of the sliding sleeve extends to the inside of the vertical drainage pipe through the through opening, the bottom end of the compression washer is fixedly connected to the bottom of the inner wall of the closed top ring, and the upper part of the outer surface of the sliding sleeve is slidably connected to the bottom of the inner cavity of the closed top ring.

[0011] First, install the device on the outer surface of the boiler where it is needed, select a long strip of heat-resistant coil, and curl the heat-resistant coil into a cylindrical structure along the outer surface of the boiler to ensure that the surrounding guide rail on the inner wall of the heat-resistant coil completely fits the outer surface of the boiler. Since the two ends of the heat-resistant coil cannot be perfectly docked, use a limit cassette to limit the heat-resistant coil and lock the heat-resistant coil to the outer surface of the boiler. Then install the drainage component and the pressurizing component on the outside of the heat-resistant coil to complete the preparation work, add seawater through the water injection pipe, use the waste heat of the boiler to evaporate the seawater into water vapor, use the pressurizing component for auxiliary work, and recover the liquid fresh water condensed from the water vapor through the oblique drainage shell.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can wrap the outer surface of the boiler with a heat-resistant coil, and use the waste heat from the outer surface of the boiler to directly heat the surrounding guide rail, so that the seawater inside the surrounding guide rail can absorb heat and evaporate into water vapor, and then condense the water vapor into liquid water, thereby obtaining fresh water resources. Since the main energy consumed in the entire work comes from the waste heat generated by the boiler, it can improve the utilization rate of energy and reduce the energy loss caused by the boiler's own heating. In addition, the heat-resistant coil of the device can wrap the outer surface of the boiler, thereby preventing external personnel from being injured due to contact with the high-temperature outer surface of the boiler.

[0014] 2. The heat-resistant coil of the device can be reshaped according to the actual shape of the outer surface of the boiler to ensure that the surrounding guide rail can be close to the outer surface of the boiler to absorb heat. Since the heat-resistant coil is short, it cannot completely wrap the boiler, so that the distillation component can be completely fitted to the outer surface of the boiler, and there will be no problem of uneven heating of the internal seawater due to excessive distillation component surplus.

[0015] 3. The pressurized component installed on the top of the device provides auxiliary functions. On the one hand, it can accelerate the discharge of fresh water resources inside the water storage bottom belt by pressurizing and reduce the siltation of water bodies. On the other hand, the pressurized cold air can accelerate the condensation of high-temperature water vapor inside the vertical drainage pipe, thereby cooling the vertical drainage pipe and reducing the pressure inside the vertical drainage pipe to avoid the problem of the inner wall of the vertical drainage pipe bursting due to high temperature and high pressure.

[0016] 4. When the sliding push block is pressurized, the air pressure inside the closed top ring will be discharged into the vertical drainage tube through the downward drainage groove, and pressurize the isolation rubber pad inside the sliding sleeve, so that the pressure-bearing sleeve can feedback the pressure inside the closed top ring, avoiding the problem of the closed top ring bursting due to excessive pressure inside the closed top ring that exceeds its own bearing capacity.

DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 , the present invention provides a technical solution: a boiler flue gas seawater desalination device, comprising a surrounding component 1, a drainage component 2 is arranged at the bottom of the surrounding component 1, and a pressurizing component 3 is arranged at the top of the surrounding component 1;

[0028] The surrounding component 1 includes a heat-resistant coil 11, which is a rollable elastic plate body that can fit the round boiler to form a Figure 3 In the winding drum structure shown, the inner wall of the heat-resistant coil 11 is evenly provided with a distillation component 14, and the two sides of the outer surface of the heat-resistant coil 11 are symmetrically provided with a limit card 13, and the limit card 13 on both sides can be clamped together to solidify the curled heat-resistant coil 11, and the two sides of the inner cavity of the heat-resistant coil 11 are symmetrically provided with water injection pipes 12, and the external seawater is injected into the drainage component 2 inside the device through the water injection pipes 12 on both sides for desalination treatment;

[0029] The distillation component 14 includes a surrounding guide rail 141. The surrounding guide rail 141 and the heat-resistant coil 11 are both made of heat-resistant elastic rubber. They can be twisted with the bending deformation of the heat-resistant coil 11 and directly fit the outer surface of the boiler. The top of the inner cavity of the surrounding guide rail 141 is evenly provided with bending transfer tubes 142 through the through opening. The bottom of the inner wall of the bending transfer tube 142 is fixedly connected with a jet end 143. The end of the inner wall of the bending transfer tube 142 away from the surrounding guide rail 141 is fixedly connected with a conical inner sleeve 144. The conical inner sleeve 144 is an outwardly expanding structure. Without affecting the discharge of water vapor, it prevents external liquid water from flowing back into the inside of the bending transfer tube 142.

[0030] The drainage component 2 includes a water storage bottom belt 21, which stores condensed liquid water. Vertical drainage pipes 23 are evenly arranged on the top of the inner cavity of the water storage bottom belt 21. Condensation pipes 25 are evenly arranged on the side of the inner cavity of the vertical drainage pipe 23 away from the bent transfer pipe 142. One end of the condensation pipe 25 extends to the outside of the vertical drainage pipe 23 for heat dissipation. Water vapor that contacts the condensation pipe 25 will quickly release heat and liquefy. After absorbing heat, the condensation pipe 25 will quickly dissipate heat through the end extending to the outside of the vertical drainage pipe 23. Both ends of the water storage bottom belt 21 are fixedly connected with an oblique drainage shell 22.

[0031] There are three surrounding guide rails 141, the outer surface of the surrounding guide rails 141 is fixedly connected to the inner wall of the heat-resistant coil 11, the top of the bent transfer tube 142 is plugged into the inner cavity of the vertical drainage pipe 23 through the docking socket 24, and the inner wall of the water storage bottom belt 21 is fixedly connected to the bottom of the outer surface of the heat-resistant coil 11. The rear end of the water injection pipe 12 is fixedly connected to one end of the surrounding guide rail 141, and there are six water injection pipes 12. The outer surface of the limit card belt 13 is rotatably connected to the outer surface of the heat-resistant coil 11, and the bottom end of the vertical drainage pipe 23 extends to the inside of the water storage bottom belt 21.

[0032] First, install the device on the required outer surface of the boiler, select a long heat-resistant coil 11, and curl the heat-resistant coil 11 into a cylindrical structure along the outer surface of the boiler to ensure that the surrounding guide rail 141 on the inner wall of the heat-resistant coil 11 is completely in contact with the outer surface of the boiler. Since the two ends of the heat-resistant coil 11 cannot be perfectly docked, use a limiting tape 13 to limit the heat-resistant coil 11 and lock the heat-resistant coil 11 to the outer surface of the boiler. Then install the drainage component 2 and the pressure component 3 on the outside of the heat-resistant coil 11 to complete the preparation work.

[0033] Seawater is added to the internal surrounding guide rail 141 through the water injection pipe 12. Since the surrounding guide rail 141 is in close contact with the outer surface of the boiler, the waste heat of the flue gas generated when the boiler is working will directly heat the surrounding guide rail 141, thereby causing the inner wall of the surrounding guide rail 141 to be in a high temperature state. At this time, the seawater inside the surrounding guide rail 141 will absorb heat and become water vapor through the jet end 143. Under the guidance of the bent transfer pipe 142, it will enter the interior of the vertical drainage pipe 23. Since the top of the vertical drainage pipe 23 is blocked by the pressurized component 3, the high-temperature water vapor accumulated in the vertical drainage pipe 23 will be condensed into water droplets due to the heat absorption of the condensation pipe 25, and fall into the bottom of the water storage bottom belt 21. After accumulation, more fresh water is stored in the interior of the water storage bottom belt 21, and then discharged through the oblique drainage shell 22 inclined downward to obtain fresh water resources.

[0034] Example 2, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the pressurizing component 3 includes a closed top ring 31, a control push plate 32 is fixedly connected to one side of the inner wall of the closed top ring 31 near the limit card belt 13, sliding push blocks 33 are symmetrically arranged on both sides of the inner wall of the control push plate 32, and the sliding push blocks 33 completely fill and block the inner wall of the closed top ring 31, and cold air pressurizers 34 are symmetrically arranged on both sides of the outer surface of the closed top ring 31, and the cold air pressurizers 34 can pressurize the inside of the closed top ring 31 and cool down the pressurized gas through the internal air conditioner, and the bottom of the inner cavity of the closed top ring 31 is evenly provided with one-way nozzles 35. The lower surface of the closed top ring 31 is plugged with the top end of the vertical drainage pipe 23, the air jet of the cold air pressurizer 34 extends to the inside of the closed top ring 31, and the outer surface of the cold air pressurizer 34 is fixedly connected to the outer surface of the closed top ring 31, and the outer surface of the sliding push block 33 is slidably connected to the inner wall of the closed top ring 31.

[0035] The one-way nozzle 35 includes a sliding sleeve 351, a compression washer 353 is sleeved on the upper part of the outer surface of the sliding sleeve 351, drainage grooves 352 are evenly opened on the upper part of the inner cavity of the sliding sleeve 351, a pressure-bearing sleeve 355 is fixedly connected to the bottom of the inner wall of the sliding sleeve 351, and an isolation rubber pad 354 is fixedly connected to the top of the output shaft of the pressure-bearing sleeve 355. The bottom end of the sliding sleeve 351 extends to the inside of the vertical drainage pipe 23 through the through opening, the bottom end of the compression washer 353 is fixedly connected to the bottom of the inner wall of the closed top ring 31, and the upper part of the outer surface of the sliding sleeve 351 is slidably connected to the bottom of the inner cavity of the closed top ring 31.

[0036] During operation, the cold air pressurizers 34 located on both sides of the closed top ring 31 first pressurize and cool the interior of the closed top ring 31, and then control the push plate 32 to control the sliding push blocks 33 on both sides to push outward, so that the pressure in the area of ​​the one-way nozzle 35 is further increased, thereby discharging the cold air in the form of high pressure through the one-way nozzle 35 downward into the interior of the vertical drainage pipe 23. At this time, the high-temperature water vapor inside the vertical drainage pipe 23 dissipates heat and condenses, and is discharged to the oblique drainage shells 22 on both sides under the action of high pressure, thereby accelerating the condensation process of water vapor and effectively dissipating heat from the vertical drainage pipe 23.

[0037] After the sliding push block 33 is pushed to the farthest point, the control push plate 32 needs to retract the sliding push block 33. At this time, the pressure in the area where the one-way nozzle 35 is located will decrease. In order to prevent the water vapor inside the vertical drainage pipe 23 from flowing back into the closed top ring 31, causing the control push plate 32 and the cold air pressurizer 34 to become damp, the one-way nozzle 35 is modified. At this time, the sliding sleeve 351 will slide up due to the lowered internal pressure of the closed top ring 31, and the drainage groove 352 will completely enter the closed top ring 31, and the closed top ring 31 and the vertical drainage pipe 23 will be completely separated by the compression gasket 353 and the sliding sleeve 351 to prevent the water vapor from flowing back.

[0038] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
