Description

Technical Field

[0001] This utility model relates to the field of dehydrogenation tower technology, and in particular to a dehydrogenation tower device for removing water vapor. Background Technology

[0002] A dehydrogenation tower is a piece of equipment used in propane dehydrogenation processes. It is a key component of this process, achieving highly efficient conversion of propane to propylene through its unique design and operating principle, which is of great significance to the chemical industry.

[0003] Chinese Patent Publication No. (CN218076443U) discloses a refining dehydrogenation tower, including a tank body. An outlet pipe is connected to the upper end of the tank body, and a feed pipe is fixedly connected to the side of the tank body. A preheating pipe is installed on the outer wall of the feed pipe near the tank body. Pressure sensors are sequentially arranged on the preheating pipe away from the tank body. Each pressure sensor includes a sensing housing, which is fixedly connected to the feed pipe. A sliding valve is slidably connected to the feed pipe near the sensing housing, and a piston is fixedly connected to the upper end of the sliding valve. A spring is fixedly connected to the piston at the end away from the sliding valve. This invention achieves automatic control of the tank body pressure without affecting the internal temperature of the tank by setting a sensing housing and connecting the outlet pipe to the upper part of the sensing housing cavity. The spring pushes the sliding valve to cut off the feed pipe, causing the tank to lose gas supply. After continuous discharge, the feed pipe is restored, achieving automatic control of the tank body pressure without affecting the internal temperature of the tank.

[0004] However, the above-mentioned utility model still has the following problems: when the above-mentioned device is used to dehydrogenate propane, a certain amount of water vapor will be generated during the catalytic dehydrogenation process. This water vapor will affect the dehydrogenation effect and quality. The above-mentioned utility model does not have the effect of removing water vapor, so it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a dehydrogenation tower device for removing water vapor, which facilitates the removal of water vapor and the replacement of activated carbon adsorption plates.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dehydrogenation tower for removing water vapor includes a processing box, an outlet pipe fixedly connected to the upper surface of the processing box, an inlet pipe fixedly connected to the lower surface of the processing box, a fixed frame inside the processing box, an activated carbon adsorption plate inside the fixed frame, a sealing plate fixedly connected to one side of the fixed frame, a drive box fixedly connected to the outer surface of the processing box, a drive motor fixedly connected to the side of the drive box away from the processing box, a threaded screw fixedly connected to the output end of the drive motor, a limit screw block threadedly connected to the outer wall of the threaded screw block, an L-shaped connecting rod fixedly connected to the top of the limit screw block, a connecting plate fixedly connected to one end of the L-shaped connecting rod, and the connecting plate fixedly connected to the sealing plate.

[0007] By adopting the above technical solution, and by setting up a treatment box, an outlet pipe, an inlet pipe, a fixed frame, an activated carbon adsorption plate, a sealing plate, a drive box, a drive motor, a threaded screw, a limiting screw block, an L-shaped connecting rod, and a connecting plate, the device allows hydrogen and water vapor to enter the treatment box through the outlet pipe during use. After passing through the activated carbon adsorption plate in the treatment box, the activated carbon adsorption plate adsorbs the water vapor. The hydrogen, after the water vapor is removed, re-enters the dehydrogenation tower through the inlet pipe. When it is necessary to replace the activated carbon adsorption plate, the drive motor rotates the threaded screw, which in turn drives the limiting screw block and the L-shaped connecting rod to move the sealing plate and the fixed frame to the right until the fixed frame moves outside the treatment box. At this point, the activated carbon adsorption plate inside the fixed frame can be replaced. This design not only achieves the effect of removing water vapor but also facilitates the replacement of the activated carbon adsorption plate used for removing water vapor, enhancing the practicality of the device.

[0008] A further feature of this invention is that one end of both the air outlet pipe and the air inlet pipe is fixedly connected to a connecting flange, and there are two connecting flanges. A valve is provided on the outer surface of the air outlet pipe.

[0009] By adopting the above technical solution and setting up connecting flanges, it is easy to fix the gas outlet pipe and gas inlet pipe to the dehydrogenation tower.

[0010] A further feature of this invention is that a screw fixing seat is fixedly connected to the inner wall of the drive box, a bearing is provided inside the screw fixing seat, and the threaded screw is rotatably connected to the screw fixing seat through the bearing.

[0011] By adopting the above technical solution, and by setting the screw fixing seat and bearing, the screw is fixed and supported, and the screw can be rotated.

[0012] A further feature of this invention is that a limiting groove is formed on the upper surface of the drive box, and the L-shaped connecting rod is slidably connected to the limiting groove.

[0013] By adopting the above technical solution and setting a limiting groove, the movement range of the L-shaped connecting rod is limited.

[0014] A further feature of this invention is that a placement tray is fixedly connected to the inner wall of the fixed frame, and the placement tray is located below the activated carbon adsorption plate.

[0015] By adopting the above technical solution and setting up a support plate, the activated carbon adsorption plate can be supported.

[0016] A further feature of this invention is that a rectangular sealing gasket is fixedly connected to the side of the sealing plate near the fixed frame, and the rectangular sealing gasket is sleeved with the fixed frame.

[0017] By adopting the above technical solution and setting a rectangular sealing gasket, the sealing performance between the sealing plate and the treatment box can be effectively enhanced, preventing hydrogen from leaking out from the gap between the sealing plate and the treatment box.

[0018] A further feature of this invention is that a lateral fixing plate is fixedly connected to the inner wall of the fixing frame, and a tail fixing plate is fixedly connected to the inner wall of the fixing frame.

[0019] By adopting the above technical solution, and by setting lateral fixing plates and tail fixing plates, the fixing frame is supported and fixed on both sides and at the tail.

[0020] A further feature of this invention is that the number of the lateral fixing plates is four, and the number of the tail fixing plates is two, wherein one of the tail fixing plates and the two lateral fixing plates are located below the fixing frame.

[0021] By adopting the above technical solution, the four lateral fixing plates are located above and below the two sides of the fixing frame, and the tail fixing plate is located above and below the tail of the fixing frame, which plays a supporting and fixing role for the fixing frame.

[0022] A further feature of this invention is that the inner wall of the fixed frame is provided with a sliding groove, the inner wall of the sliding groove is slidably connected with a limit strip, and the inner wall of the fixed frame is provided with a hidden groove, which communicates with the sliding groove.

[0023] By adopting the above technical solution, and by setting a limiting strip in conjunction with the placement tray below the activated carbon adsorption plate, the activated carbon adsorption plate is fixed.

[0024] A further feature of this invention is that: an installation plate is fixedly connected to the outer surface of the drive box, a synchronization cylinder is fixedly connected to the outer surface of the installation plate, and a top plate is fixedly connected to the output end of the synchronization cylinder; the number of the synchronization cylinder and the top plate are both two.

[0025] By adopting the above technical solution, and by setting up a sliding groove, limiting strips, a hidden groove, a mounting plate, a synchronous cylinder, and a top plate, when the fixed frame moves to the outside of the processing box under the drive motor, the two limiting strips can be moved to slide into the hidden groove. When the limiting strips are in the hidden groove, they lose their limiting effect on the top of the activated carbon adsorption plate. Then, the two synchronous cylinders work to drive the top plate to move upward until the top plate contacts the activated carbon adsorption plate in the fixed frame, thus pushing the activated carbon adsorption plate out of the fixed frame. This design achieves the effect of automatically lifting the activated carbon adsorption plate in the fixed frame, avoiding the inconvenience of manually removing the activated carbon adsorption plate, which is heavy and has absorbed a lot of water vapor. This further improves the device's ability to easily replace the activated carbon adsorption plate, thereby enhancing the ease of use of the device.

[0026] The beneficial effects of this utility model are as follows: By setting up a treatment box, an outlet pipe, an inlet pipe, a fixed frame, an activated carbon adsorption plate, a sealing plate, a drive box, a drive motor, a threaded screw, a limiting screw block, an L-shaped connecting rod, and a connecting plate, the device allows hydrogen and water vapor to enter the treatment box through the outlet pipe during use. After passing through the activated carbon adsorption plate in the treatment box, the activated carbon adsorption plate adsorbs the water vapor. The hydrogen, after removing the water vapor, re-enters the dehydrogenation tower through the inlet pipe. When the activated carbon adsorption plate needs to be replaced, the drive motor rotates the threaded screw, which in turn drives the limiting screw block and the L-shaped connecting rod to move the sealing plate and the fixed frame to the right until the fixed frame moves outside the treatment box. At this point, the activated carbon adsorption plate inside the fixed frame can be replaced. This design not only achieves the effect of removing water vapor but also facilitates the removal of water vapor. The replacement of activated carbon adsorption plates enhances the practicality of the device. By incorporating a sliding groove, limiting strips, a concealed groove, a mounting plate, synchronous cylinders, and a top plate, when the fixed frame moves outside the treatment box under the drive motor, the two limiting strips can be moved to slide into the concealed groove. When the limiting strips are in the concealed groove, they lose their limiting effect on the top of the activated carbon adsorption plate. Then, the two synchronous cylinders operate, driving the top plate upwards until it contacts the activated carbon adsorption plate inside the fixed frame, thus pushing the activated carbon adsorption plate out of the fixed frame. This design achieves an automatic lifting effect for the activated carbon adsorption plate inside the fixed frame, avoiding the inconvenience of manually removing the heavily weighted activated carbon adsorption plate, which is full of water vapor. This further improves the device's ease of replacement of activated carbon adsorption plates, thereby enhancing its usability. Attached Figure Description

The hydrogen, after removing the water vapor, re-enters the dehydrogenation tower through the inlet pipe 3. When the activated carbon adsorption plate 5 needs to be replaced, the drive motor 8 rotates the threaded screw 9, which in turn drives the limiting screw block 10 and the L-shaped connecting rod 11 to move the sealing plate 6 and the fixed frame 4 to the right until the fixed frame 4 is outside the treatment box 1. At this point, the activated carbon adsorption plate 5 inside the fixed frame 4 can be replaced. This design not only achieves the effect of removing water vapor, but also facilitates the replacement of the activated carbon adsorption plate 5 used for removing water vapor, enhancing the practicality of the device. One end of the outlet pipe 2 and the inlet pipe 3 are fixedly connected to a connecting flange 13. There are two connecting flanges 13. A valve 14 is provided on the outer surface of the outlet pipe 2. By setting the connecting flanges 13, it is easy to fix the outlet pipe 2 and the inlet pipe 3 to the dehydrogenation tower. A screw fixing seat 15 is fixedly connected to the inner wall of the drive box 7. A bearing is set inside the screw fixing seat 15.

A limiting groove 16 is provided on the upper surface of the drive box 7, and the L-shaped connecting rod 11 is slidably connected to the limiting groove 16. The limiting groove 16 restricts the movement range of the L-shaped connecting rod 11. A placement plate 17 is fixedly connected to the inner wall of the fixed frame 4, positioned below the activated carbon adsorption plate 5. The placement plate 17 provides support for the activated carbon adsorption plate 5. A rectangular sealing gasket 18 is fixedly connected to the side of the sealing plate 6 near the fixed frame 4. The rectangular sealing gasket 18 fits into the fixed frame 4. The rectangular sealing gasket 18 effectively enhances the sealing performance between the sealing plate 6 and the treatment box 1, preventing hydrogen from leaking out from the gap between the sealing plate 6 and the treatment box 1.The inner wall of the fixed frame 4 is fixedly connected with side fixing plates 19 and tail fixing plates 20. The side fixing plates 19 and tail fixing plates 20 provide support and fixation for the sides and tail of the fixed frame 4. There are four side fixing plates 19 and two tail fixing plates 20. One tail fixing plate 20 and two side fixing plates 19 are located below the fixed frame 4. The four side fixing plates 19 are located above and below the sides of the fixed frame 4, respectively. The tail fixing plate 20... The 0 is located above and below the tail of the fixed frame 4, serving to support and fix the fixed frame 4. The inner wall of the fixed frame 4 has a sliding groove 21, and the inner wall of the sliding groove 21 is slidably connected to a limit strip 22. The inner wall of the fixed frame 4 has a hidden groove 23, which communicates with the sliding groove 21. By setting the limit strip 22, in conjunction with the placement plate 17 below the activated carbon adsorption plate 5, it serves to fix the activated carbon adsorption plate 5. The outer surface of the drive box 7 is fixedly connected to a mounting plate 24, and the outer surface of the mounting plate 24 is fixedly connected to... Synchronous cylinder 25, with a top plate 26 fixedly connected to its output end. There are two synchronous cylinders 25 and two top plates 26. By configuring a sliding groove 21, limiting strips 22, a concealed groove 23, a mounting plate 24, synchronous cylinders 25, and top plates 26, when the fixed frame 4 moves to the outside of the processing box 1 under the drive of the drive motor 8, the two limiting strips 22 can be moved to slide into the concealed groove 23. When the limiting strips 22 are in the concealed groove 23, they lose their resistance to the top of the activated carbon adsorption plate 5. The device uses a limiting mechanism, and then two synchronized cylinders 25 operate to drive the top plate 26 upward until it contacts the activated carbon adsorption plate 5 inside the fixed frame 4, thus pushing the activated carbon adsorption plate 5 out of the fixed frame 4. This design achieves the automatic lifting effect of the activated carbon adsorption plate 5 inside the fixed frame 4, avoiding the inconvenience of manually removing the heavily weighted activated carbon adsorption plate 5, which is full of water vapor. This further improves the ease of replacing the activated carbon adsorption plate 5 and enhances the convenience of using the device.

[0035] In this invention, a treatment box 1, an outlet pipe 2, an inlet pipe 3, a fixed frame 4, an activated carbon adsorption plate 5, a sealing plate 6, a drive box 7, a drive motor 8, a threaded screw 9, a limiting screw block 10, an L-shaped connecting rod 11, and a connecting plate 12 are provided. During use, hydrogen and water vapor enter the treatment box 1 through the outlet pipe 2. After passing through the activated carbon adsorption plate 5 in the treatment box 1, the activated carbon adsorption plate 5 adsorbs the water vapor. The hydrogen, after removing the water vapor, re-enters the dehydrogenation tower through the inlet pipe 3. When the activated carbon adsorption plate 5 needs to be replaced, the drive motor 8 rotates the threaded screw 9, which in turn drives the limiting screw block 10 and the L-shaped connecting rod 11 to move the sealing plate 6 and the fixed frame 4 to the right until the fixed frame 4 is outside the treatment box 1. At this point, the activated carbon adsorption plate 5 inside the fixed frame 4 can be replaced. This design not only achieves effective water vapor removal but also facilitates the replacement of the activated carbon adsorption plate used for water vapor removal. The replacement of the auxiliary plate 5 enhances the practicality of the device. By setting up the sliding groove 21, limiting strip 22, hidden groove 23, mounting plate 24, synchronous cylinder 25, and top plate 26, when the fixed frame 4 moves to the outside of the treatment box 1 under the drive of the drive motor 8, the two limiting strips 22 can be moved to slide into the hidden groove 23. When the limiting strips 22 are in the hidden groove 23, they lose their limiting effect on the top of the activated carbon adsorption plate 5. Then, the two synchronous cylinders 25 work to drive the top plate 26 to move upward until the top plate 26 contacts the activated carbon adsorption plate 5 in the fixed frame 4, thus pushing the activated carbon adsorption plate 5 out of the fixed frame 4. This design achieves the effect of automatically lifting the activated carbon adsorption plate 5 in the fixed frame 4, avoiding the situation where the activated carbon adsorption plate 5, which is full of water vapor, is too heavy to be easily removed manually. This further improves the device's ability to easily replace the activated carbon adsorption plate 5, thereby enhancing the ease of use of the device.
