Through desulfurization treatment, reduce the sulfur dioxide emission in natural gas, not only help to slow down the formation of acid rain, protect the natural environment, is the important measure to protect the environment and human health.

[0004] Specifically, during the desulfurization process, when the desulfurization rich liquid formed by the reaction of desulfurization lean liquid and natural gas falls from the through hole on the baffle to the bottom of the absorption tank, it will cause blockage of the through hole.

[0026] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0027] Embodiment one

[0028] Please refer to Figures 1-5 The desulfurization device for natural gas purification of the present embodiment includes a box body 2 and a partition plate 5 arranged inside the box body 2. The box body 2 is connected with an air inlet pipe 1 on one side and an air outlet pipe 4 on the top. A spraying module 6 is arranged on the top of the inner cavity.

[0029] A bearing ring 7 connected with the inner wall of the box body 2 is arranged around the partition plate 5. The inner ring of the bearing ring 7 is connected with the outer ring of the partition plate 5 through a connecting ring 8.

[0030] A plurality of through holes 12 are arranged on the top of the partition plate 5. A plurality of plugging columns 13 adapted to the through holes 12 are arranged on the bottom of the partition plate 5.

[0031] The bottom of the box 2 is provided with a sliding through the box 2 push structure, the output end of the push structure is connected with a plurality of blocking columns 13 through a connecting frame, and the top of the partition plate 5 is provided with a cleaning structure.

[0032] Natural gas is introduced into the inside of the box 2 through the gas inlet pipe 1. In the initial stage, the blocking column 13 on the partition plate 5 is away from the through hole 12, which makes the through hole 12 keep open. Natural gas enters the top space of the box 2 through these open through holes 12. Then, the push structure is activated, the connecting frame is moved, and then the plurality of blocking columns 13 are connected with the corresponding through holes 12, so as to close the through holes 12.

[0033] Once the through hole 12 is closed, the spray module 6 starts to work, and sprays the desulfurization lean liquid to the top space of the box 2. The desulfurization lean liquid fully contacts and reacts with the natural gas already gathered on the top of the box 2, and the natural gas is desulfurized. The desulfurization rich liquid produced in the desulfurization process and the mixture of the desulfurization lean liquid which is not completely reacted fall on the partition plate 5 under the action of gravity. Since the through hole 12 is closed by the blocking column 13 at this time, the desulfurization rich liquid will not penetrate into the through hole 12, thereby effectively avoiding the problem of through hole blockage.

[0034] After the desulfurization treatment is completed, the natural gas is discharged out of the box 2 through the gas outlet pipe 4 and enters the subsequent processing or conveying link. The desulfurization rich liquid falling on the top of the partition plate 5 is cleaned by the cleaning structure. The cleaning structure cleanses all the desulfurization rich liquid to the surrounding support ring 7. The support ring 7 acts as a collection structure and can temporarily store these liquids for subsequent processing or discharge.

[0035] Example two

[0036] Please refer to Figures 1-5 As shown in the figure, the top outer ring of the support ring 7 is fixedly connected with an annular protrusion, and the outer ring of the support ring 7 is bolted and fixedly connected with the inner wall of the box 2. Specifically, during installation, the support ring 7 is first fixedly connected with the inner wall of the box 2 through the bolts of the outer ring, so as to ensure that the support ring 7 is stably installed in the box 2. The design of the annular protrusion enhances the connection and sealing between the support ring 7 and the box 2, and also provides a better support basis for the cleaning structure. The installation stability and sealing performance of the support ring 7 are improved, which ensures that the desulfurization rich liquid can be smoothly cleaned into the support ring 7 and will not leak to other parts of the box 2, and simplifies the subsequent processing process.

[0037] The connecting ring 8 is conical in shape, the top of the connecting ring 8 is connected with the bottom of the partition plate 5, the bottom is connected with the top of the supporting ring 7, the side is inclined, the inside of the supporting ring 7 is detachably connected with the collecting ring 11, the top of the collecting ring 11 is provided with a collecting cavity, specifically, when the desulfurization rich liquid falls on the partition plate 5, due to the conical design of the connecting ring 8, the rich liquid will flow along the inclined side to the supporting ring 7, reducing the retention on the partition plate 5. Improve the flow path of the desulfurization rich liquid, reduce the accumulation of the rich liquid on the partition plate 5, improve the cleaning efficiency, and at the same time reduce the risk of corrosion of the partition plate 5.

[0038] Example three

[0039] Please refer to Figures 1-5 The desulfurization device for natural gas purification of the embodiment is shown, the pushing structure includes a lifting cylinder 10 installed at the bottom of the box 2, the output end of the lifting cylinder 10 slides through the bottom of the box 2, specifically, when the through hole 12 needs to be closed, the lifting cylinder 10 is started, the output end moves upward, drives the blocking column 13 to rise through the connecting frame, connects with the through hole 12, and realizes the closing of the through hole. A stable and reliable source of pushing force is provided, so that the blocking column 13 can be accurately and quickly connected with the through hole 12, improving the working efficiency and automation degree of the device.

[0040] The cleaning structure includes a driving motor 3 installed at the top of the box 2 and a cleaning plate 9 arranged at the top of the partition plate 5, the output shaft of the driving motor 3 is in transmission connection with the top of the cleaning plate 9, specifically, after the desulfurization treatment is completed, the driving motor 3 is started, the output shaft drives the cleaning plate 9 to rotate, and the desulfurization rich liquid on the top of the partition plate 5 is cleaned into the supporting ring 7. The automatic cleaning of the desulfurization rich liquid is realized, the cleaning efficiency and accuracy are improved, the manual intervention is reduced, and the labor intensity is reduced.

[0041] The connecting frame includes a plurality of horizontal rods and vertical rods, the plurality of horizontal rods and the plurality of vertical rods are connected with each other and the top of each is connected with the adjacent blocking column 13, the output end of the lifting cylinder 10 is connected with the bottom of the horizontal rod, specifically, when the lifting cylinder 10 is started, the output end drives multiple blocking columns 13 to rise or fall through the connecting frame composed of horizontal rods and vertical rods, realizing the batch opening or closing of the through hole 12. A stable and uniform pushing force transmission path is provided, ensuring that all blocking columns 13 can be moved synchronously and accurately, improving the working reliability and stability of the device.

[0042] The scheme has the following working process:

[0043] Natural gas is introduced into the inside of the box 2 through the gas inlet pipe 1. In the initial stage, the blocking columns 13 on the partition plate 5 are away from the through holes 12, and the through holes 12 remain open, and the natural gas enters the top space of the box 2 through the open through holes 12. Then, the lifting cylinder 10 is started, and the output end moves upward, drives the multiple blocking columns 13 to rise synchronously through the connecting frame, is connected with the corresponding through hole 12, and the through hole is closed.

[0044] Once the through hole 12 is closed, the spraying module 6 starts to work, and sprays the desulfurization lean liquid to the top space of the box 2. The desulfurization lean liquid fully contacts and reacts with the natural gas gathered on the top of the box 2, and the natural gas is desulfurized. The desulfurization rich liquid and the mixture of the desulfurization lean liquid which is not completely reacted in the desulfurization process drop on the partition plate 5 under the action of gravity. Since the through hole 12 is closed by the blocking column 13 at this time, the desulfurization rich liquid cannot penetrate into the inside of the through hole 12, and the problem of through hole blockage is effectively avoided. The desulfurization rich liquid flows along the inclined side surface of the connecting ring 8 to the supporting ring 7, and is finally collected into the collection cavity of the collection ring 11.

[0045] After the desulfurization treatment is completed, the natural gas is discharged out of the box 2 through the gas outlet pipe 4 and enters the subsequent processing or conveying link. At the same time, the driving motor 3 is started, and the output shaft drives the cleaning plate 9 to rotate, and the residual desulfurization rich liquid on the top of the partition plate 5 is cleaned into the supporting ring 7, and it is further ensured that the desulfurization rich liquid cannot leak to other parts of the box 2.

[0046] Beneficial effects: the device realizes batch opening or closing of the through hole 12 through the cooperation of the lifting cylinder 10 and the connecting frame, improves the working efficiency and automation degree of the device, improves the flow path of the desulfurization rich liquid through the design of the conical connecting ring 8 and the supporting ring 7, reduces the accumulation of the rich liquid on the partition plate 5, improves the cleaning efficiency, and reduces the risk of corrosion of the partition plate 5; through the cooperation of the driving motor 3 and the cleaning plate 9, the desulfurization rich liquid is quickly cleaned, the cleaning efficiency and accuracy are improved, manual intervention is reduced, and the labor intensity is reduced; through the design of the collection ring 11, the desulfurization rich liquid is temporarily stored, and the subsequent processing process is simplified.
