[0002] A methanol-to-olefin device is an important device in the entire process of a coal-to-olefin process, and a regenerator is a core device of the device, which is used for burning coke from a reactor to be regenerated catalyst. In the prior art, the bottom of a first cyclone separator in the regenerator is designed as an anti-inversion cone, which can ensure that the leg has sufficient flux during stable operation of the device.

[0003] However, since the end of the leg at the bottom of the first cyclone separator in the regenerator is designed as an anti-inversion cone, there is no catalyst in the leg at the bottom of the cyclone separator when a complete fluidization state is not established in the regenerator (during start-up), the space in the container is directly connected with the catalyst outlet of the cyclone separator, which easily causes a large amount of catalyst loss during start-up, and if a wing valve is arranged at the end of the leg at the bottom of the first cyclone separator in the regenerator, sufficient unloading amount cannot be maintained during stable operation. SUMMARY

[0004] The present application aims to provide a leg baffle and a regenerator cyclone leg structure, and aims to solve the technical problems in the prior art that catalyst loss occurs when the leg at the bottom of the separator does not establish a complete fluidization state, and a wing valve cannot maintain sufficient unloading amount during stable operation.

[0005] In order to achieve the above-mentioned application purposes, the present application provides a leg baffle in one aspect, which comprises a support plate for being fixed on a leg of a regenerator cyclone separator, and a baffle plate for shielding an anti-inversion cone outlet of the leg, the baffle plate is hinged to the support plate, and the baffle plate is made of a combustible material.

[0006] In some embodiments, the leg baffle further comprises a skeleton net connected to the support plate, and the baffle plate is pressed on the skeleton net by a mold through the combustible material.

[0007] In some embodiments, the leg baffle further comprises a counterweight support plate, an upper end of the counterweight support plate is connected to the support plate, a lower end of the counterweight support plate is connected to the skeleton net, and the counterweight support plate is a solid metal plate.

[0008] In some embodiments, the leg baffle further comprises a skeleton net pull rod arranged between the counterweight support plate and the skeleton net, an upper part of the skeleton net pull rod is connected to the counterweight support plate, and a lower part of the skeleton net pull rod is connected to the skeleton net.

[0009] In some embodiments, the dipleg baffle further comprises a pivot shaft and one or more pivot shaft tubes fixed on the support plate, the pivot shaft being inserted into the pivot shaft tubes and connected with the baffle.

[0010] In some preferred embodiments, the bending arc of the support plate is consistent with the arc of the dipleg, the bending arc of the pivot shaft is smaller than the bending arc of the support plate, and the bending arc of the pivot shaft tube is smaller than the bending arc of the support plate.

[0011] In some embodiments, one or more anchor nails are fixed on the back of the support plate away from the baffle.

[0012] Another aspect of the present application provides a regenerator cyclone dipleg structure, comprising: a dipleg of a regenerator cyclone having an inner cavity, a plurality of anti-inversion cone support legs arranged at the bottom of the dipleg, an anti-inversion cone pyramid arranged below the anti-inversion cone support legs, and a dipleg baffle as described above, the space between two adjacent anti-inversion cone support legs being an anti-inversion cone outlet, the inner cavity of the dipleg being in communication with the anti-inversion cone outlet, the support plate of the dipleg baffle being fixed with the dipleg, and the baffle shielding the anti-inversion cone outlet.

[0013] In some embodiments, the regenerator cyclone dipleg structure comprises a plurality of the dipleg baffles, and the support plates of the plurality of the dipleg baffles are fixedly connected with the dipleg after being annularly spliced.

[0015] The present application sets a baffle made of combustible material at the anti-inversion cone outlet position of the dipleg, thereby preventing the medium from flowing back into the interior of the dipleg through the baffle when there is no material level established in the interior of the dipleg, and when the regenerator is in a stable working condition and the baffle is no longer needed, the baffle burns out and disappears quickly under the action of combustion and the erosion and abrasion of a large amount of catalyst in the dipleg, thus no longer hindering the normal discharge of the anti-inversion cone. Therefore, the present application plays the role of the baffle at the start-up and avoids hindering the normal working condition. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0027] The specific embodiments of the present application are further described below with reference to the accompanying drawings. The same parts are denoted by the same reference signs in the description below. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a specific part.

[0028] As Figure 1 shown in FIG. 1 is a baffle for the leg of the regenerator cyclone, which comprises a support plate 1 for being fixed on the leg 001 of the regenerator cyclone, and a baffle 2 for shielding the anti-inversion outlet 004 of the leg 001, the baffle 2 is hinged to the support plate 1, the baffle 2 is made of a combustible material, the combustion temperature of the combustible material is lower than the internal temperature of the regenerator in stable working condition, and the combustion temperature of the combustible material is higher than the internal temperature of the regenerator during start-up.

[0029] Specifically, the leg baffle at least comprises a support plate 1 and a baffle 2 hinged to the support plate 1. By hinging, a greater discharge amount is obtained when the internal level of the leg is too high, avoiding the leg from being full of material.

[0030] The support plate 1 is used to be fixed on the leg 001, and the baffle 2 is used to shield the anti-inverted cone outlet 004. As shown in Figure 9 The figure shows a schematic view of the internal structure of the regenerator, the leg 001 is the leg of the bottom of the cyclone 006 of the regenerator 005. The leg of the cyclone 006 of the regenerator 005 is preferably the leg of the first-stage cyclone of the regenerator 005. When the complete fluidization state is not established inside the regenerator 005, i.e. when the catalyst inside the regenerator is not in the fluidization state (during start-up), there is no catalyst in the leg 001 of the bottom of the cyclone 006, and the space inside the container is directly in communication with the catalyst outlet of the cyclone 006. During start-up, the catalyst is first added, and then the main air is blown in, so that the catalyst inside the regenerator becomes in the fluidization state. However, during start-up, when the level is not established inside the leg 001 of the cyclone 006 of the regenerator 005, the catalyst will enter the cyclone 006 with the flue gas, thereby causing a large amount of catalyst to be lost during start-up. The present embodiment blocks the anti-inverted cone outlet 004 by the baffle 2. Since the temperature inside the regenerator is lower than the combustion temperature of the baffle 2 when the level is not established inside the leg 001, the baffle 2 does not burn, thereby blocking the medium including the catalyst inside the regenerator 005 from flowing backward into the inside of the cyclone through the anti-inverted cone outlet 004 when the level is not established inside the leg 001 of the cyclone of the regenerator, thereby reducing the catalyst loss phenomenon in the regenerator during start-up.

[0031] In one embodiment, the combustion temperature of the combustible material is higher than the internal temperature of the regenerator when the level is not established inside the leg of the cyclone of the regenerator during start-up of the regenerator.

[0032] Preferably, the combustion temperature of the combustible material is higher than the internal temperature of the regenerator when the level is not established inside the leg of the first-stage cyclone of the regenerator.

[0033] After the fluidization state inside the regenerator is stable and the material level is established in the material leg 001, the regenerator is already in a stable operating condition. Under stable operating conditions, the catalyst enters the material leg 001 from the cyclone separator 006, and then enters the anti-back cone outlet 004 from the material leg 001, and returns to the inside of the regenerator 005. Since there is a certain level of catalyst in the material leg 001, this part of the catalyst prevents the flue gas from flowing back into the material leg 001 through the anti-back cone outlet 004 due to the stacking density. Therefore, under this operating condition, the baffle is no longer needed. Under stable operating conditions, the temperature of the regenerator rises to the combustion temperature of the baffle 2. Therefore, the baffle 2 fails to burn and quickly disappears under the action of combustion and the erosion and wear of a large amount of catalyst in the material leg 001, and no longer hinders the normal discharge of the anti-back cone. Among them, the stable operating condition of the regenerator refers to the period after the fluidization state inside the regenerator is stable and the material level is established in the material leg 001.

[0034] In one embodiment, the combustion temperature of the combustible material is lower than the internal temperature of the regenerator when the regenerator is in a stable operating condition.

[0035] Preferably, the combustible material is a mixture of carbon powder, silicon oxide powder, aluminum oxide powder, a binder and water.

[0036] Preferably, the combustion temperature of the combustible material is above 600°C, that is, when the regenerator temperature rises to 600°C, the baffle 2 begins to burn, and as the regenerator temperature continues to rise, the burning speed of the baffle 2 accelerates until it disappears.

[0037] The present invention installs a baffle made of combustible material at the outlet of the anti-backflow cone of the dip leg. This prevents backflow of the medium into the dip leg when the material level is not established. However, when the regenerator reaches a stable operating state, the baffle is no longer needed. The baffle burns out and quickly disappears due to combustion and the erosion of the large amount of catalyst in the dip leg, no longer hindering normal discharge of the anti-backflow cone. This serves the purpose of a baffle during operation while also preventing obstruction to normal operation.

[0038] like Figures 1 to 4 As shown, in another embodiment of the present invention, a dipleg baffle comprises: a support plate 1 for fixing on a dipleg 001 of a regenerator cyclone separator, a baffle 2 for shielding an anti-cone outlet 004 of the dipleg 001, a skeleton net 3 connected to the support plate 1, a counterweight support plate 4, a skeleton net tie rod 5, a rotating shaft 6, and one or more rotating shaft tubes 7, wherein the baffle 2 is connected to the support plate 1 and is made of a combustible material;

[0039] The baffle 2 is made of the combustible material and pressed onto the skeleton net 3 through a mold. The upper end of the counterweight support plate 4 is connected to the support plate 1, and the lower end of the counterweight support plate 4 is connected to the upper part of the skeleton net tie rod 5. The lower part of the skeleton net tie rod 5 is connected to the skeleton net 3. The counterweight support plate 4 is a solid metal plate.

[0040] The rotating shaft tube 7 is fixed on the support plate 1, the rotating shaft 6 is inserted into the rotating shaft tube 7 and connected to the baffle 2, the curvature of the support plate 1 is consistent with the curvature of the material leg 001, the curvature of the rotating shaft 6 is smaller than the curvature of the support plate 1, and the curvature of the rotating shaft tube 7 is smaller than the curvature of the support plate 1;

[0041] One or more anchoring nails 8 are fixed to the back side of the support plate 1 away from the baffle 2 .

[0042] Specifically, the dipleg baffle provided in this embodiment prevents the medium inside the regenerator from flowing back into the cyclone separator through the anti-backward cone outlet during startup, i.e., when the material level is not established inside the dipleg of the regenerator cyclone, especially when the material level is not established inside the dipleg of the first-stage cyclone, thereby reducing the phenomenon of medium leakage within the regenerator during startup. Furthermore, the baffle does not obstruct the anti-backward cone discharge after the fluidization state inside the regenerator is stable and the material level is established in the dipleg.

[0043] The support plate 1, preferably the root support plate, is made by bending a stainless steel plate. Preferably, the curvature of the support plate 1 is consistent with the curvature of the leg 001 of the regenerator cyclone separator, and the width is one-fourth of the circumference of the leg 001. Figure 3 As shown, a plurality of anchoring nails 8 are welded on the back of the support plate 1. The anchoring nails can adopt various existing anchoring nail forms. When the thickness of the support plate 1 meets the design anti-scour requirements, it can be directly welded on the material leg 001 without setting the anchoring nails 8.

[0044] A pivot tube 7 is welded to the front of the support plate 1. The pivot tube 7 is preferably a support pull ring. Preferably, the pivot tube 7 is a thick-walled stainless steel tube slightly bent, with a curvature smaller than that of the support plate 1. When the pivot tube 7 is fitted to the support plate 1, a gap exists due to the slight difference in curvature, which is filled with welding material.

[0045] The rotating shaft 6 is preferably a crankshaft, which is made of a solid stainless steel cylinder with a slight bend. The bending curvature is smaller than the curvature of the material leg 001 and the diameter is smaller than the rotating shaft tube 7.

[0046] The curvature design of the rotating shaft tube 7 and the rotating shaft 6 can be replaced by a straight shaft plus a limiter.

[0047] In one embodiment, the rotating shaft 6 is a straight shaft, and the rotating shaft tube 7 is a non-bending steel tube provided with a limiter.

[0048] The counterweight support plate 4 is made of solid metal plate, the bending curvature is preferably consistent with the rotating shaft 6, the shape is convex, the width is slightly smaller than the width of the anti-inverted cone support leg 002, the upper center protrusion is welded to the rotating shaft 6, and the lower part is connected to the framework net pull rod 5. The rotating shaft pipe 7 can be multiple, the rotating shaft 6 is inserted into the multiple rotating shaft pipes 7, and the counterweight support plate 4 is connected between the gaps of the adjacent two rotating shaft pipes 7.

[0049] The framework net pull rod 5 is made of solid or hollow metal, the bending curvature is preferably consistent with the rotating shaft 6 and the counterweight support plate 4, the upper part is welded to the counterweight support plate 4, and the lower part is connected to the framework net 3.

[0050] The framework net 3 is mainly made of asbestos fiber, part of metal wires are mixed inside to increase the tensile strength, and the upper part is connected to the framework net pull rod 5 through bundling, clamping, bolt fastening and the like.

[0051] The baffle 2 is made of combustible material. Preferably, carbon powder, silicon oxide powder, aluminum oxide powder, adhesive and water are mixed to form a mold, which is pressed on the framework net 3, and the baffle is formed after drying (drying) and dehydration. Preferably, the baffle 2 has the same curvature as the rotating shaft 6 and the counterweight support plate 4, and the width is consistent with the counterweight support plate 4. The baffle 2 and the framework net 3 are tightly connected to the counterweight support plate 4 through the framework net pull rod 5.

[0052] In the embodiment, the baffle made of combustible material is arranged at the anti-inverted cone outlet position of the material leg, so that when there is no material level in the material leg, the medium is prevented from flowing into the material leg through the baffle. When the regenerator is in stable working condition, the baffle is burned out and disappears quickly under the action of combustion and the erosion and wear of a large amount of catalyst in the material leg, so as not to hinder the normal discharge of the anti-inverted cone. Therefore, the baffle plays a role in starting, and avoids hindering the normal working condition.

[0053] In addition, the anchor nails are arranged at the rear of the support plate, the anchor nails are embedded in the inner liner and do not contact the metal inner wall of the material leg, and the four support plates are welded to each other to reduce the local stress of the liner area and increase the wear resistance of the area. Through the curvature design of the rotating shaft pipe and the rotating shaft, the baffle can only be opened and closed slightly, and cannot be opened and closed greatly due to the bending of the rotating shaft and the stress contact of the rotating shaft pipe. At the same time, the counterweight support plate solves the problem that the baffle is light in weight and shakes violently when the regenerator is in a fluidized state. The counterweight support plate and the baffle are tightly connected through the design of the framework net pull rod and the framework net.

[0054] As Figures 5 to 8As shown, the embodiment of the application is a kind of regenerator cyclone leg structure, comprising: the leg 001 of the regenerator cyclone separator with inner cavity, a plurality of anti-inverted taper support legs 002 arranged at the bottom of the leg 001, an anti-inverted taper cone 003 arranged below the anti-inverted taper support leg 002, and the leg baffle as described above, the space between adjacent two anti-inverted taper support legs 002 is an anti-inverted taper outlet 004, the inner cavity of the leg 001 is communicated with the anti-inverted taper outlet 004, and the support plate 1 of the leg baffle is fixed with the leg 001, and the baffle 2 shields the anti-inverted taper outlet 004.

[0055] Specifically, the aforementioned leg baffle of the application is arranged on the leg 001 of the regenerator cyclone separator. The bottom of the leg 001 is provided with a plurality of anti-inverted taper support legs 002 and an anti-inverted taper cone 003. The leg 001, the anti-inverted taper support leg 002 and the anti-inverted taper cone 003 are sequentially connected. The connection mode can be achieved by using the existing connection mode of the anti-inverted taper type regenerator cyclone leg. The space between adjacent two anti-inverted taper support legs 002 is an anti-inverted taper outlet 004. The support plate 1 of the leg baffle is fixed with the leg 001, and the baffle 2 shields the anti-inverted taper outlet 004. The leg 001 is preferably the leg of the first-stage cyclone separator of the regenerator. When the complete fluidization state is not established in the regenerator (during start-up), there is no catalyst in the leg 001 at the bottom of the cyclone separator, and the space in the container is directly communicated with the anti-inverted taper outlet 004 of the cyclone separator. During start-up, the catalyst is first added, and then the main air is blown in to make the catalyst in the regenerator become fluidized. However, during start-up, when the material level is not established in the leg 001 of the cyclone separator 006 of the regenerator 005, the catalyst will enter the cyclone separator 006 with the flue gas, thereby causing a large amount of catalyst to be lost during start-up. In this embodiment, the baffle 2 shields the anti-inverted taper outlet 004. Since the temperature in the regenerator is lower than the combustion temperature of the baffle 2 when the material level is not established in the leg 001, the baffle 2 does not burn, thereby blocking the medium including the catalyst in the regenerator 005 from flowing back into the cyclone separator through the anti-inverted taper outlet 004 when the material level is not established in the leg 001 of the regenerator cyclone separator, thereby reducing the catalyst loss during start-up.

[0056] In one of the embodiments, the combustion temperature of the combustible material is higher than the temperature in the regenerator when the material level is not established in the leg of the regenerator cyclone separator during start-up of the regenerator.

[0057] Preferably, the combustion temperature of the combustible material is higher than the temperature in the regenerator when the material level is not established in the leg of the first-stage cyclone separator of the regenerator.

[0058] After the fluidization state inside the regenerator is stabilized and the material level inside the anti-inversion leg 001 is established, the regenerator is in a stable working condition. In the stable working condition, the catalyst enters the anti-inversion leg 001 from the cyclone separator 006, and then enters the anti-inversion outlet 004 from the anti-inversion leg 001, and returns to the inside of the regenerator 005. Because there is a certain amount of catalyst in the anti-inversion leg 001, the part of the catalyst is prevented from flowing back into the anti-inversion leg 001 by the smoke gas through the anti-inversion outlet 004 due to the bulk density. Therefore, in this working condition, the baffle is no longer needed. In the stable working condition, the temperature of the regenerator is increased to the combustion temperature of the baffle 2, and therefore the baffle 2 is burned out, and is quickly removed under the action of combustion and the large amount of catalyst in the anti-inversion leg 001, and no longer blocks the normal discharge of the anti-inversion leg 001.

[0059] In one of the embodiments, the combustion temperature of the combustible material is lower than the internal temperature of the regenerator in the stable working condition of the regenerator.

[0060] As shown in Figure 7 and Figure 8 In one of the embodiments, the anti-inversion leg baffle includes a plurality of the support plates 1, and the support plates 1 are fixedly connected to the anti-inversion leg 001 after being annularly spliced.

[0061] In one of the embodiments, the anti-inversion leg 001 includes a metal pipe and a liner wrapped around the metal pipe, and the anchor nails 8 of the support plates 1 are connected to the liner.

[0062] The baffle 2 is designed to be burned out when the temperature of the regenerator is increased to the working condition, which not only plays the role of the baffle at the start of the work, but also avoids hindering the normal working condition.

[0063] The installation method of the anti-inversion leg baffle of the best embodiment of the present application is as follows:

[0064] 1. The carbon powder, silicon oxide powder, aluminum oxide powder, binder and water are mixed, and then are pressed on the framework net 3 to form the baffle 2, and the baffle 2 is tightly connected with the counterweight support plate 4 after being dried (dried) and dehydrated;

[0065] 2. The liner at the position of the support plate 1 installed on the anti-inversion leg 001 is removed, and the four support plates 1 are annularly spliced and then are welded together. The support plate 1 is used as a template for pouring the liner, and the liner material is poured into the template for pouring;

[0066] The liner construction process is similar to the cement construction. Before the construction, the liner material is poured into the template (usually wooden), and the template is removed after the liner material is solidified. The template can not be set during the liner construction at this position, and the support plate 1 is directly used as the template for pouring the liner;

[0067] 3. The rotating shaft 6 is inserted into the rotating shaft pipe 7;

[0068] 4. The counterweight support plate 4 convex type with the shaft 6 center part welding, make counterweight support plate 4, baffle 2 through the shaft 6 installation on the support plate 1.

[0069] The present application sets a baffle made of combustible material at the anti-inversion outlet position of the leg, thereby preventing the medium from flowing back into the leg through the baffle when no material level is established inside the leg. When the regenerator is in a stable working condition and the baffle is no longer needed, the baffle burns out and disappears quickly under the action of combustion and the erosion and abrasion of a large amount of catalyst in the leg, thus no longer hindering the normal discharge in the anti-inversion position. The baffle plays a role in starting up and avoids hindering the normal working condition.

[0070] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
