Description

Technical Field

[0001] This utility model relates to the field of ship exhaust gas treatment technology, and in particular to a liquid spraying device for use in ship exhaust gas scrubbing machines. Background Technology

[0002] The basic principle of hypergravity engineering technology is to utilize the unique flow behavior of multiphase flow systems under hypergravity conditions. The main way to obtain hypergravity is to generate a centrifugal force field by rotating the entire equipment or its components. The multiphase flow systems involved mainly include gas-solid systems and gas-liquid systems. The gas phase is introduced tangentially into the outer cavity of the rotor through the gas inlet pipe. Under the action of gas pressure, it enters the metal wire mesh packing from the outer edge of the rotor. The liquid is introduced into the inner cavity of the rotor through the liquid inlet pipe and sprayed onto the inner edge of the rotor through the nozzle. The liquid entering the rotor is affected by the packing inside the rotor, and its circumferential velocity increases. The resulting centrifugal force pushes it towards the outer edge of the rotor. During this process, the liquid is dispersed and broken by the packing, forming a large and constantly renewed surface area. The tortuous flow channel intensifies the renewal of the liquid surface. In this way, excellent mass transfer and reaction conditions are formed inside the rotor. The liquid is thrown by the rotor to the outer shell, collects, and leaves through the liquid outlet pipe.

[0003] When the air scrubber is working, the rotor can reach a speed of hundreds or even thousands of revolutions per minute under the drive of the rotating shaft. Due to the effect of gravity, the top part of the outer side of the packing cannot be well covered, resulting in a waste of efficiency. Utility Model Content

[0024] Example:

[0025] Reference Figures 1-4A liquid spraying device for a ship exhaust gas scrubber includes a scrubber body 10, and further includes: a rotor rotatably disposed within the scrubber body 10, packing 3 disposed within the rotor, and a liquid inlet pipe 8 fixedly disposed within the scrubber body 10. A second spray hole 801 is formed on the side wall of one end of the liquid inlet pipe 8 extending into the packing 3; a liquid seal structure is disposed between the top of the rotor and the top of the scrubber body 10, which can achieve a seal between the top of the rotor and the top of the scrubber body 10, reducing the entry of gas or particulate matter from above the rotor into the exhaust pipe 7, thus preventing normal operation; a through hole 1 is formed on the top of the rotor, with both ends of the through hole 1 connected to the packing 3 and the liquid seal structure respectively; and a first spray hole 4 is formed on the side wall of the liquid inlet pipe 8, which is connected to the liquid seal structure. The main function of the first spray hole 4 is... It supplies liquid to the liquid seal structure, providing a reaction liquid as the liquid seal liquid. During use, the liquid is sprayed into the liquid seal structure through the first nozzle 4. When gas or solid particles flow through the sealing area of ​​the liquid seal structure, the density and viscosity of the liquid inside the liquid seal structure will form a sealing layer. This liquid sealing layer can prevent gas leakage and also absorb and block the movement of solid particles, playing an effective role in isolation and sealing. During this process, a small portion of the liquid used for sealing can enter the top area of ​​the packing 3 through the through hole 1, and be thrown off by the high-speed rotation of the packing 3. Under the premise of meeting the sealing requirements, the sealing liquid at the liquid seal is effectively utilized. The structure is simple, safe and reliable, easy to operate and maintain, and greatly improves the absorption efficiency of the packing 3, which has good market application prospects.

[0026] Reference Figure 3 and Figure 4Here, the liquid seal structure includes a first cylinder 5 fixedly connected to the top of the rotor, and a second cylinder 501 fixedly installed on the top of the air scrubber body 10. The diameter of the second cylinder 501 is smaller than that of the first cylinder 5, and it extends into the first cylinder 5. A first annular plate extending into the liquid inlet pipe 8 is fixedly installed on the top of the first cylinder 5. A gap is left between the inner wall of the first annular plate and the outer wall of the second cylinder 501. A second annular plate is fixedly installed at one end of the second cylinder 501 extending into the first cylinder 5. Similarly, a gap is left between the outer wall of the second annular plate and the inner wall of the first cylinder 5. The second annular plate is located between the first annular plate and the top end face of the rotor, and gaps are left on both the upper and lower end faces. The liquid sealant is introduced to improve the sealing effect. A first sealing gasket is installed at the bottom of the first cylinder 5 and the top of the rotor. Similarly, a second sealing gasket is installed at the top of the second cylinder 501 and the top of the inner part of the air scrubber body 10. The first cylinder 5 is detachably connected to the top of the rotor via a first bolt, and the second cylinder 501 is detachably connected to the top of the inner part of the air scrubber body 10 via a second bolt. During use, the first nozzle 4 sprays the reaction liquid between the top of the second annular plate and the top of the cover plate 2. When the rotor rotates at high speed, the reaction liquid can flow out along the channel between the second annular plate and the first annular plate. At this time, the density and viscosity of the liquid will form a sealing layer, effectively isolating and sealing the liquid. When the first nozzle 4 sprays the reaction liquid between the top of the second annular plate and the top of the cover plate 2, a small portion can enter the top area of ​​the packing 3 through the through hole 1. The high-speed rotation of the packing 3 causes the liquid to be thrown out, achieving effective utilization of the sealing liquid at the liquid seal while meeting the sealing requirements.

[0027] Reference Figures 1-3 An air inlet pipe 6 is fixedly installed on the side wall of the air scrubber body 10, and an air outlet pipe 7 is fixedly installed on the top of the air scrubber body 10. The air inlet end of the air outlet pipe 7 is connected to the packing 3. In use, the exhaust gas enters the air scrubber body 10 through the air inlet pipe 6, and after being absorbed by the packing 3, it can be discharged from the air outlet pipe 7.

[0028] Reference Figures 1-3 A liquid outlet pipe 9 is fixedly installed at the bottom of the gas scrubber body 10, and a valve is fixedly installed on the liquid outlet pipe 9. During use, the reaction liquid accumulated inside the gas scrubber body 10 can be conveniently discharged by fixing the liquid outlet pipe 9 on the gas scrubber body 10.

[0029] Reference Figure 3Here, the rotor includes a base plate and a cover plate 2. The base plate is rotatably located at the bottom of the air scrubber body 10, and a motor for driving the base plate to rotate is fixedly installed on the air scrubber body 10. The base plate and the cover plate 2 are fixedly connected by a support rod. That is, the bottom of the support rod is fixed to the base plate with bolts, and the top of the support rod is also fixed to the cover plate 2 with bolts. At this time, the packing 3 can be clamped between the base plate and the cover plate 2, and the outer wall of the packing 3 abuts against the support rod, and the inside is set to abut against the sleeve with mesh, so as to fix the packing 3. The structure is simple, safe and reliable, easy to operate and maintain. The packing 3 is fixedly set between the base plate and the cover plate 2, and through holes 1 are opened on the cover plate 2. Multiple sets of through holes 1 are evenly opened, ranging from two to twenty sets. Here, we prefer sixteen sets, which are evenly distributed in a circle. In use, by the rotor consisting of a base plate and a cover plate 2, it is convenient to fix the packing 3. It has a simple structure, is safe and reliable, easy to operate and maintain, and is conducive to widespread use.

[0030] Reference Figure 3 A sleeve is provided between the base plate and the cover plate 2. The top of the sleeve abuts against the bottom of the cover plate 2, and the bottom of the sleeve abuts against the top of the base plate. Limiting rings are fixedly provided at the top of the base plate and the bottom of the cover plate 2. The two ends of the sleeve are respectively fitted onto the limiting rings. Mesh holes are provided on the side wall of the sleeve, and the inner wall of the packing 3 abuts against the outer wall of the sleeve, so that the second spray hole 801 is located inside the sleeve. In use, by providing a sleeve with mesh holes between the base plate and the cover plate 2, not only can the inner wall of the packing 3 be limited, but the liquid sprayed from the second spray hole 801 can also easily enter the packing 3.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
