Description

Technical Field

[0001] The invention belongs to the technical field of catalyst regeneration, and in particular relates to a catalyst in-situ regeneration device. Background Art

[0002] Catalysts play a key role in chemical reactions. They can speed up or slow down the reaction rate by providing new reaction paths or reducing the activation energy of the reaction. Catalysts do not change the total energy change of the reaction, that is, they do not change the thermodynamic properties of the reaction, but they can change the kinetic properties of the reaction, so that the reaction is completed at a lower temperature, pressure or in a shorter time. Catalysts can be divided into metal catalysts and non-metal catalysts according to the type of their active components. However, during the use of the catalyst, it will gradually lose its activity due to carbon deposition. In order to fully utilize the catalyst and restore its activity, the catalyst needs to be regenerated.

[0003] In-situ regeneration technology regenerates the catalyst in the reactor, avoiding the process of removing and reloading the catalyst. It has the advantages of simple operation and low cost, and can repair deactivated catalysts in time, improving reaction efficiency and product quality.

[0004] The existing catalyst regenerator mainly includes a tower body, an auxiliary heater, an air distribution device, a cyclone separator, etc. When in use, air and the catalyst to be regenerated are injected into the tower body, the air is heated by the auxiliary heater, and then the high-temperature gas is uniformly sprayed out by the air distribution device, and the catalyst to be regenerated enters the tower body from the pipeline and contacts with the high-temperature gas, thereby burning off the carbon deposits. The sintered flue gas will be discharged through the cyclone separator at the top, and part of the flue gas carrying the catalyst will be sent back to the air distribution device by the cyclone separator. After running for a certain period of time, the air injection is stopped, so that the catalyst with carbon deposits removed can fall from the tower body and be discharged from the bottom. However, the existing catalyst regenerator has the following problems:

[0005] When the catalyst to be regenerated enters the tower body through the tower body pipeline, it is in a concentrated state, so it takes a certain amount of time for the airflow of the air distribution device to completely disperse the catalyst to be regenerated; in addition, due to the different carbon deposition levels on the surface of the catalyst to be regenerated after use, the size and weight of the catalyst particles to be regenerated are also different. Therefore, after entering the tower body, part of the catalyst to be regenerated may not be effectively lifted by the airflow, resulting in insufficient time for the high-temperature gas to fully contact this part of the catalyst to be regenerated. Summary of the invention

[0022] The guide section opened at the rectangular groove port of the present invention not only allows the high-temperature rising airflow ejected by the air distribution mechanism to pass through, but also guides the catalyst dropped from above when the air distribution mechanism stops distributing air to avoid residue.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Reference Figure 1-Figure 10 As shown, the present invention provides a catalyst in-situ regeneration device, comprising a tower body 1 for catalyst in-situ regeneration, an auxiliary heating mechanism 2, an air distribution mechanism 3, a cyclone separator 4 and a feed pipe 5, and a dispersion mechanism 6 and a receiving mechanism 7 are arranged inside the tower body 1; the dispersion mechanism 6 and the receiving mechanism 7 are made of high temperature resistant materials to adapt to the environment inside the tower body 1; the dispersion mechanism 6 and the receiving mechanism 7 can be disassembled for easy maintenance;

[0041] The dispersion mechanism 6 includes a dispersion box 61, a baffle 64 and a transmission assembly 66. The feed pipe 5 is fixedly connected to the top of the dispersion box 61, and the transmission assembly 66 is movably connected to the inside of the dispersion box 61. The transmission assembly 66 includes a half-frame slider 661, a transmission column 662, a linkage plate 664, a connecting rod 665 and a connector 667. The transmission assembly 66 is used to trigger the baffle 64 to expand and guide the airflow. The dispersion mechanism 6 is used to disperse the catalyst to be regenerated entering from the feed pipe 5; both ends of the connecting rod 1 663, the connecting rod 2 666 and the connecting rod 3 794 are connected by an insertion rod, and can rotate around the insertion rod as the center, and are equipped with bearings;

[0042] The receiving mechanism 7 includes a receiving plate 71, a receiving net 76, a linkage rod 78 and a linkage assembly 79. The linkage rod 78 and the linkage assembly 79 are both slidably connected inside the receiving plate 71. The receiving net 76 is used to carry part of the catalyst to be regenerated. The linkage assembly 79 includes a sloped top block 791, a bottom rod 792 and a support plate 793. The linkage assembly 79 is used to cooperate with the transmission assembly 66 to unfold the receiving net 76; the receiving net 76 is a wire mesh used at the bottom of the reactor or tower body in the prior art, which has the characteristics of high temperature resistance, corrosion resistance, and not easy to deform. In addition, the material and structural design of the wire mesh make it have sufficient air permeability and porosity, thereby allowing the rising airflow at the bottom to pass smoothly without significantly hindering the airflow. The mesh aperture is one to two millimeters smaller than the catalyst particle diameter.

[0043] In a further embodiment, the receiving plate 71 is provided with a docking notch 74, the inner wall of the docking notch 74 is provided with a linkage slide groove 75, the dispersion box 61 is installed inside the docking notch 74, the dispersion box 61 is provided with a guide channel 62 running through the upper and lower parts, the upper port of the guide channel 62 is installed with a baffle net 63, the baffle plate 64 is installed at the lower port of the guide channel 62, and the baffle plate 64 is connected to the lower end of the dispersion box 61 through a hinge.

[0044] In this embodiment, the linkage slide groove 75 has a certain cavity inside the receiving plate 71, which facilitates the sliding of the linkage component 79 and the rotation of the receiving net 76. In addition, an arc groove is opened on the inner wall of the rectangular groove 72, and the arc groove is connected to the cavity of the linkage slide groove 75, so that the linkage rod 78 can rotate with the receiving net 76 around the connecting shaft 77. Figure 7 The connecting part of the linkage slide groove 75 and the transmission slide groove 65 is shown in the figure, so that the connecting piece 667 is slidably connected in both the transmission slide groove 65 and the linkage slide groove 75 for transmission; the blocking net 63 is used to prevent the catalyst from directly passing through the guide channel 62 to the top of the gas distribution mechanism 3. In addition, the blocking net 63 is made of the same material as the receiving net 76.

[0045] In a further embodiment, a transmission chute 65 is opened inside the dispersion box 61 and the feed pipe 5, the transmission chute 65 is connected to the linkage chute 75, the half-frame slider 661, the transmission column 662 and the connecting rod 665 are all slidably connected inside the transmission chute 65, and evenly arranged springs 668 are arranged below the half-frame slider 661, and the springs 668 are located inside the transmission chute 65.

[0046] In this embodiment, the cross-sectional shape of the transmission slot 65 is consistent with the half-frame slider 661, so that the half-frame slider 661, the transmission column 662, and the connecting rod 665 can slide conveniently inside the transmission slot 65; the spring 668 is used to reset the height of the entire half-frame slider 661. After the half-frame slider 661 is reset, the baffle 64 will close the lower port of the guide channel 62, and when closing, the baffle 64 will continue to be pushed by the upward airflow, so the baffle 64 closes relatively slowly, but it also allows the upper port of the guide channel 62 to have time to disperse the last part of the catalyst to be regenerated that enters from the feed pipe 5.

[0047] In a further embodiment, the transmission column 662 is fixedly connected to the upper end of the half-frame slider 661, the connecting rod 665 is fixedly connected to the lower end of the half-frame slider 661, the connecting piece 667 is fixedly connected to both sides of the half-frame slider 661, and part of the connecting piece 667 is slidably connected to the inside of the transmission slide groove 65 and the linkage slide groove 75. The lower end of the transmission assembly 66 is rotatably connected to the connecting rod 2 666, and the end of the connecting rod 2 666 away from the connecting rod 665 is rotatably connected to the inner side of the baffle 64.

[0048] In this embodiment, the side opening of the transmission slide groove 65 is connected to the linkage slide groove 75, so that the connecting member 667 can slide up and down, and the connecting member 667 is L-shaped.

[0049] In a further embodiment, the linkage plate 664 is rotatably connected to the inner wall of the feed pipe 5 , one side of the linkage plate 664 is rotatably connected to a connecting rod 663 , and one end of the connecting rod 663 away from the linkage plate 664 is rotatably connected to the transmission column 662 .

[0050] In this embodiment, the two ends of the linkage plate 664 are rotatably connected to the inner wall of the discharge port of the feed pipe 5 through a convex shaft, and then after the catalyst to be regenerated enters the interior of the feed pipe 5, the linkage plate 664 will be pressed down and rotated, thereby causing the transmission column 662 to move downward through the connecting rod 663, and after being poured out, the catalyst to be regenerated will pass over the linkage plate 664.

[0051] In a further embodiment, the receiving plate 71 is provided with evenly arranged rectangular grooves 72, the upper and lower ends of the rectangular grooves 72 are provided with guide cut surfaces 73, and the two sides of the receiving net 76 are fixedly connected with connecting shafts 77. The receiving net 76 is rotatably connected to the inner wall of the rectangular groove 72 through the connecting shafts 77, and the receiving net 76 is symmetrically distributed inside the rectangular groove 72.

[0052] In this embodiment, the rectangular groove 72 is formed so that the top of the receiving plate 71 has a "well"-shaped direction, and the guide section 73 is formed at the edge of the direction, thereby preventing some large particles of the catalyst to be regenerated from accumulating at the direction. In addition, the edge of the rectangular groove 72 close to the receiving plate 71 is an arc-shaped section, thereby guiding the airflow.

[0053] In a further embodiment, the linkage assembly 79 is located inside the linkage slide groove 75, one end of the inclined top block 791 is rotatably connected to the connecting rod three 794, one end of the connecting rod three 794 away from the inclined top block 791 is rotatably connected to the connecting piece 667, the linkage rod 78 is located above the support plate 793, the bottom rod 792 is fixedly connected to the bottom of the support plate 793, and the bottom end of the bottom rod 792 is in contact with the inclined top block 791.

[0054] In this embodiment, when the half-frame slider 661 moves up and down with the connecting piece 667, it will slide with the inclined top block 791, thereby controlling the expansion or closing of the receiving net 76; the inclined top block 791 is composed of three trapezoidal guide blocks and two connecting blocks, and the guide blocks are used to lift the bottom rod 792, so that the linkage rod 78 can rotate with the receiving net 76 around the connecting shaft 77.

[0055] In a further embodiment, the linkage rod 78 is located between two adjacent receiving nets 76, and both ends of the linkage rod 78 are fixedly connected to the receiving nets 76. The linkage rod 78 can be connected to the shaft 77 as a rotating shaft for rotation.

[0056] In this embodiment, there are two receiving nets 76 in each rectangular groove 72 and they are symmetrical to each other, and a single receiving net 76 is connected to the receiving net 76 in another rectangular groove 72 through a linkage rod 78, so that the linkage rod 78 can control the rotation of the receiving net 76.

[0057] In a further embodiment, the auxiliary heating mechanism 2, the air distribution mechanism 3 and the cyclone separator 4 are installed inside the tower body 1 from bottom to top, the air distribution mechanism 3 is connected to the output port of the auxiliary heating mechanism 2, the air distribution mechanism 3 is located below the receiving mechanism 7 and the dispersing mechanism 6, the cyclone separator 4 is located above the receiving mechanism 7 and the dispersing mechanism 6, and the feed pipe 5 is fixedly connected to one side of the tower body 1.

[0058] In this embodiment, the tower body 1, the auxiliary heating mechanism 2, the air distribution mechanism 3, the cyclone separator 4 and the feed pipe 5 constitute a regenerator for in-situ regeneration of the catalyst in the prior art, wherein the auxiliary heating mechanism 2 has an air injection pipe for connecting to the outside, so as to heat the air and spray it out evenly from the output port of the air distribution mechanism 3, the cyclone separator 4 is used to discharge the flue gas that burns the carbon on the surface of the catalyst, and the catalyst entering the interior will be separated and transported to the top of the receiving mechanism 7 through the bottom pipeline, so that the high-temperature airflow of the receiving mechanism 7 can be used to process this part of the catalyst again, and the feed pipe 5 is used to inject the catalyst to be regenerated into the interior of the tower body 1.

[0059] The working principle of the present invention is as follows:

[0060] When the catalyst to be regenerated enters the interior of the tower body 1 through the feed pipe 5, the linkage plate 664 will be tilted and rotated, and then the cylinder connecting rod 1 663 will make the transmission column 662 move downward, thereby moving the half-frame slider 661, the connecting rod 665 and the connecting piece 667 downward, and compressing the spring 668 at the bottom of the half-frame slider 661. In the process of moving downward, the connecting rod 665 will rotate and unfold the baffle 64 at the bottom of the dispersion box 61 through the connecting rod 2 666, so that the high-temperature rising airflow ejected by the air distribution mechanism 3 will be guided by the baffle 64 to the interior of the guide channel 62 and ejected from the baffle 63. At this time, the catalyst to be regenerated passing above the baffle 63 will be dispersed and blown to the interior of the tower body 1, thereby avoiding the concentration of the catalyst to be regenerated entering the tower body 1.

[0061] During the downward movement of the semi-frame slider 661, the connecting rod 665 and the connecting piece 667, the connecting piece 667 will move the inclined top block 791 to the left through the connecting rod three 794, so that the bottom rod 792 inside the receiving plate 71 will move up with the supporting plate 793, and the supporting plate 793 will lift the linkage rod 78 between the receiving net 76 during the upward movement, so that the receiving net 76 can rotate about the connecting shaft 77 until it rotates ninety degrees. At this time, the rectangular groove 72 will be closed by the receiving net 76. At this time, the large mass of catalyst particles to be regenerated will fall to the top of the receiving net 76, and the high-temperature rising airflow ejected by the gas distribution mechanism 3 can still pass through the receiving net 76. Therefore, this part of the catalyst can be fully contacted and regenerated in the high-temperature gas, avoiding the problem of poor regeneration effect caused by insufficient airflow lifting capacity.

[0062] After the carbon deposits on the surface of the above-mentioned catalyst particles to be regenerated are burned off above the receiving net 76, their mass becomes smaller and will be carried by the rising air flow and circulated and suspended inside the tower body 1. When the catalyst to be regenerated is no longer injected into the tower body 1 through the feed pipe 5, due to the rebound of the spring 668 and the fact that the baffle 64 is still blocked by the rising air flow, the half-frame slider 661 will slowly move up. At this time, the linkage plate 664 will also slowly close the inner wall of the feed pipe 5, the baffle 64 will also slowly close the guide channel 62, and the bottom rod 792 will also move down with the support plate 793. However, the receiving net 76 will also have a certain reason to block the rising air flow, and will temporarily close the rectangular groove 72 until a certain period of time later, when air is no longer injected into the auxiliary heating mechanism 2, the air distribution mechanism 3 will no longer spray high-temperature rising air flow, and the receiving net 76 will also sag again due to gravity. At this time, the regenerated catalyst will also pass through the rectangular groove 72 and be discharged from the bottom of the tower body 1 to enter the next step of processing.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
