Description

Technical Field

[0001] The present invention relates to the technical field of catalyst discharging, and particularly relates to a catalyst discharging device and a discharging system for a methanol synthesis reactor. Background Art

[0002] The catalysts of two series of methanol synthesis reactors are Clariant's copper-based catalysts for methanol synthesis. So far, the service life has reached the end of its useful life, and the reaction activity cannot meet the production requirements. Now, according to the production requirements, new catalysts need to be replaced. Since they are in a reduced state, they are extremely prone to oxidation reactions and combustion when encountering air. Therefore, before discharging the synthesis catalyst, it is necessary to passivate it first, and second, control the flow rate during the catalyst discharging process, and cool and dust-remove the waste catalyst in a timely manner.

[0003] For example, in the prior art, Chinese Patent Application No. 201921159968.3, a structure of a catalyst discharging port of a methanol synthesis tower reactor, does not perform passivation operations, which is very unsafe. Moreover, a large amount of heat may be generated when the catalyst falls, and it is relatively dangerous for personnel to manually open and close the catalyst discharging.

[0004] Therefore, we designed a catalyst discharging device and a discharging system for a methanol synthesis reactor, which can make the catalyst automatically and stably fall into the passivation reaction chamber and carry out the passivation reaction. Then, after the passivation reaction is completed, the falling speed of the catalyst discharging can be controlled to make the catalyst collected more efficiently and safely. Moreover, this device is fully automatic operation, saving manpower and can be operated safely, and can push out the catalyst better. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects existing in the prior art. The present invention provides a catalyst discharging device and a discharging system for a methanol synthesis reactor, which can make the catalyst automatically and stably fall into the passivation reaction chamber and carry out the passivation reaction. Then, after the passivation reaction is completed, the falling speed of the catalyst discharging can be controlled to make the catalyst collected more efficiently and safely.

Detailed implementation manners

[0018] It is easy to understand that according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various structural forms and implementation manners that can be mutually replaced. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention. Embodiment

[0019] Focus on reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , the vertical box frame 3 is in the shape of a box or a cylinder with an open top. Preferably, it is in the shape of a box with open top and bottom, and the middle part on the left side of the vertical box frame 3 is open. The first horizontal box frame 1 is in the shape of a box with an open right side. The open right side of the first horizontal box frame 1 is communicated with the open left side of the vertical box frame 3. It looks like a T-shaped member from the outside of the device.

[0020] Focus on reference Figure 5 , a flange 6 is fixedly installed on the outer wall of the top of the vertical box frame 3, and a plurality of mounting holes 33 are formed in the flange 6. The plurality of mounting holes 33 are evenly distributed, so that the flange 6 can be detachably installed on the discharge hole of the methanol synthesis reactor, thus facilitating the cleaning or replacement of the device.

[0021] Focus on reference Figure 6 and Figure 7 , a first limit sliding plate 8 is fixedly connected horizontally in the middle of the inner wall of the first horizontal box frame 1. A first limit chute 16 is formed in the first limit sliding plate 8. A first sliding plate 17 and a second sliding plate 34 are slidably connected left and right on the first limit chute 16. It should be noted that the right side of the first limit sliding plate 8 is closed, which is convenient for the subsequent formation of a passivation reaction chamber.

[0022] Focus on referenceFigure 6 and Figure 7 There are four articulated rods 19 hinged between the first sliding plate 17 and the second sliding plate 34, two at the front and two at the back, which are used to stably drive the second sliding plate 34 and the methanol synthesis reactor discharge port plug 20 to perform vertical movements. It should be noted that the right side of the second sliding plate 34 is longer and the left side is shorter, so that it is convenient to construct a passivation reaction chamber on the right side of the second sliding plate 34, and it is convenient to be hinged or connected in other forms on the left side of the second sliding plate 34, as long as the hinge and the construction of the passivation reaction chamber are satisfied.

[0023] For key reference Figure 6 An elastic member 18 is fixedly connected between the first sliding plate 17 and the second sliding plate 34.

[0024] For key reference Figure 6 and Figure 7 The methanol synthesis reactor discharge port plug 20 is fixedly installed at the top right of the second sliding plate 34. The cross-section of the methanol synthesis reactor discharge port plug 20 is the same as the inner cross-section of the vertical box frame 3, so that the methanol synthesis reactor discharge port plug 20 can be sealed and removed from above the vertical box frame 3 and block the methanol synthesis reactor discharge hole.

[0025] For key reference Figure 6 The second limit sliding plate 30 is fixedly installed at the bottom of the first sliding plate 17. The second limit sliding plate 30 penetrates through the first limit sliding groove 16 and the second limit sliding groove 28 opened on the lower inner wall of the first horizontal box frame 1.

[0026] For key reference Figure 6 The second horizontal box frame 2 is fixedly installed at the bottom of the first horizontal box frame 1. The front of the second horizontal box frame 2 is open, which is convenient for determining the positions of the methanol synthesis reactor discharge port plug 20 and the second sliding plate 34.

[0027] For key reference Figure 7 A threaded rod 29 is rotatably connected between the two inner walls of the second horizontal box frame 2 with limited movement. The second limit sliding plate 30 is threadedly connected to the outer wall of the threaded rod 29. Since the second limit sliding plate 30 is slidably connected to the second limit sliding groove 28 with limited movement, the rotating threaded rod 29 can drive the second limit sliding plate 30 to move left and right.

[0028] For key reference Figure 7 A small motor 15 is fixedly installed on the outer wall of the second horizontal box frame 2. The power output end of the small motor 15 is connected to the threaded rod 29, so that starting the small motor 15 drives the second limit sliding plate 30 and the first sliding plate 17 to move left and right, thereby driving the second sliding plate 34 and the methanol synthesis reactor discharge port plug 20 to perform an L-shaped movement.

[0029] It should be noted that the right side position of the first limit slide plate 8 is horizontal with the right side position of the first horizontal box frame 1. A guide post 21 is fixedly connected between the right side of the first limit slide plate 8 and the vertical box frame 3, which plays a role in guiding the second slide plate 34 and maintaining the stability of the device.

[0030] Key reference Figure 7 , a vertical baffle 23 is fixedly connected to the bottom of the right side of the first limit slide plate 8, and a heat-resistant and sealable elastic pad is arranged at the bottom of the vertical baffle 23.

[0031] Key reference Figure 7 and Figure 8 , a horizontal baffle 24 is connected to the inner bottom of the first horizontal box frame 1 in a limited sliding manner. The horizontal baffle 24 can be slidably connected to the bottom of the vertical baffle 23 left and right, and the vertical baffle 23 can seal the top of the horizontal baffle 24 through the elastic pad. An elastic telescopic member 35 is fixedly connected to the left inner wall of the first horizontal box frame 1. The elastic telescopic member 35 in the contracted state is a telescopic rod with a spring 352 inside. The elastic telescopic member 35 includes a telescopic sleeve 351. A telescopic head 353 is connected to the telescopic sleeve 351 in a limited sliding manner, and a spring 352 is fixedly connected between the telescopic head 353 and the inner bottom of the telescopic sleeve 351. That is, it normally maintains an extended action under the action of the spring 352 and is in a contracted state when the telescopic head 353 is squeezed and the spring 352 is squeezed. The telescopic head 353 on the right side of the elastic telescopic member 35 is connected to the horizontal baffle 24, so that the right side of the horizontal baffle 24 normally presses against the right inner wall of the vertical box frame 3. That is, when the rightmost sides of the second slide plate 34 and the methanol synthesis reactor discharge port plug 20 are parallel to the rightmost side of the first horizontal box frame 1, the right side of the methanol synthesis reactor discharge port plug 20, the right side of the second slide plate 34, the right side of the first limit slide plate 8, the right side of the vertical baffle 23, the top of the horizontal baffle 24, the rear inner wall of the vertical box frame 3, the right inner wall of the vertical box frame 3, and the front inner wall of the vertical box frame 3 form a passivation reaction chamber.

[0032] A water inlet pipe 22 is connected to the middle of the vertical box frame 3. The horizontal height of the water inlet pipe 22 is higher than that of the horizontal baffle 24. After the passivation reaction chamber is formed, water is introduced through the water inlet pipe 22 for catalyst passivation reaction.

[0033] Embodiment 2: On the basis of Embodiment 1, a technical means for automatically removing the horizontal baffle 24 from the passivation reaction chamber is added.

[0034] Key reference Figure 6 and Figure 7 , an auxiliary extrusion plate 25 is fixedly connected to the top of the left side of the horizontal baffle 24, and the telescopic head 353 of the elastic telescopic member 35 is fixedly connected to the auxiliary extrusion plate 25. A push plate 26 is fixedly connected to the bottom of the left side of the second slide plate 34. The push plate 26 penetrates through the first limit chute 16, and the push plate 26 is placed on the right side of the auxiliary extrusion plate 25.

[0035] It should be noted that when the push plate 26 moves upward following the second sliding plate 34, the push plate 26 will not be squeezed against the vertical baffle 23, because the left side of the second sliding plate 34 is longer, and when the plug plate 20 at the discharge port of the methanol synthesis reactor moves upward within the vertical box frame 3, the left side of the second sliding plate 34 remains within the first horizontal box frame 1.

[0036] In summary, when the second sliding plate 34 moves leftward to drive the push plate 26 to move leftward, the push plate 26 pushes the auxiliary extrusion plate 25, causing the horizontal baffle 24 to be gradually opened, and the opening degree of the horizontal baffle 24 is adjustable, thus facilitating the adjustment of the discharge speed of the catalyst.

[0037] Other structures are the same as those in the first embodiment.

[0038] Embodiment 3: On the basis of Embodiment 2, technical means for better collecting the catalyst are added.

[0039] Focus on referring to Figure 3 , a collecting conical cylinder 4 is fixedly installed at the bottom of the vertical box frame 3, and a discharge pipe 5 is connected and installed at the bottom of the collecting conical cylinder 4. The discharge pipe 5 is placed inside the barrel 7, and is used to enable the catalyst to safely enter the barrel 7.

[0040] An auxiliary pipe 14 is fixedly installed on the support rod 13. A spray head 31 is fixedly installed at the bottom of the auxiliary pipe 14, and the spray head 31 faces the inside of the barrel 7. A first pipe 11 and a second pipe 12 are installed on the water pump 10. The side of the first pipe 11 away from the water pump 10 is placed inside the water tank 9, and the side of the second pipe 12 away from the water pump 10 is communicated with the auxiliary pipe 14.

[0041] Other structures are the same as those in Embodiment 2.

[0042] In this embodiment, first, the device is fixedly installed with the discharge hole of the methanol synthesis reactor through the flange 6. Then, the small motor 15 is started to make the second limit sliding plate 30 and the first sliding plate 17 move rightward. At this time, under the action of the elastic member 18 and the hinge rod 19, the first sliding plate 17 drives the second sliding plate 34 and the plug plate 20 at the discharge port of the methanol synthesis reactor to move rightward. After the plug plate 20 at the discharge port of the methanol synthesis reactor contacts the inner wall of the vertical box frame 3, at this time, under the action of multiple hinge rods 19 and elastic members 18, the plug plate 20 at the discharge port of the methanol synthesis reactor moves upward and moves to the discharge hole of the methanol synthesis reactor to block it.

[0043] It should be noted that the top of the plug plate 20 at the discharge port of the methanol synthesis reactor is preferably horizontal.

[0044] When the catalyst in the methanol synthesis reactor needs to be unloaded, the small motor 15 is started in reverse at this time. Under the action of the elastic member 18, the plug plate 20 at the discharge port of the methanol synthesis reactor and the second sliding plate 34 move vertically downward and move to the left when the second sliding plate 34 moves to the top of the first limit sliding plate 8. The cooperation between the plug plate 20 at the discharge port of the methanol synthesis reactor and the inner wall of the first horizontal box frame 1 enables the catalyst to fall onto the top of the horizontal baffle 24, thus achieving better material discharge.

[0045] At this time, under the action of the elastic telescopic member 35, the horizontal baffle 24 has sufficient supporting force.

[0046] At this time, the right side of the plug plate 20 at the discharge port of the methanol synthesis reactor, the right side of the second sliding plate 34, the right side of the first limit sliding plate 8, the right side of the vertical baffle 23, the top of the horizontal baffle 24, the rear inner wall of the vertical box frame 3, the right inner wall of the vertical box frame 3, and the front inner wall of the vertical box frame 3 form a passivation reaction chamber. By adding water to the water inlet pipe 22, the catalyst in the passivation reaction chamber undergoes a passivation reaction.

[0047] After the reaction ends, the small motor 15 is continuously started in reverse to make the second sliding plate 34 move to the left. The second sliding plate 34 drives the push plate 26 and the auxiliary extrusion plate 25 to move to the left, so that the horizontal baffle 24 moves to the left. By adjusting the opening degree of the horizontal baffle 24, the falling speed of the catalyst is adjusted. The catalyst enters the barrel 7 from the discharge pipe 5. According to the temperature state of the barrel 7, water is sprayed through the spray head 31 for cooling.

[0048] Finally, the horizontal baffle 24, in cooperation with the vertical baffle 23, pushes all the catalysts on it into the barrel 7, completing the collection operation after the catalyst passivation.

[0049] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
