Description

Technical Field

[0001] The invention relates to the technical field of heat transfer conversion furnaces, in particular to a controllable heat transfer conversion furnace which is easy to maintain. Background Art

[0002] CO2 shift reactors are key equipment widely used in the chemical industry. Their function is to convert CO2 and water vapor into CO2 and H2 in the presence of a catalyst. Traditional shift reactors have undergone an evolution from a fully axial to a fully radial structure, effectively reducing the resistance of the catalyst bed. However, existing catalyst beds still utilize an adiabatic reaction mode and are typically divided into multiple layers, with indirect heat exchange or water-cooled cooling between the layers for temperature control. This heat exchange method presents challenges such as low heat recovery quality, insufficient sensible and latent heat recovery efficiency, catalyst overheating, and side reactions (such as methanation).

[0003] To overcome these drawbacks, various shift reactor designs have been proposed in the prior art, including single-tube, upper and lower header, plate, and upper and lower split small-tube-plate designs. These designs address, to some extent, the problems of high catalyst bed resistance, difficult unloading, and bed overheating. However, these reactors still suffer from a significant drawback: if a leak occurs in the water system, the catalyst must be removed for repair and repair, resulting in high maintenance costs and prolonged downtime.

[0004] To address this issue, patent CN105582856B proposes an improved solution. This solution utilizes a water-distributing spherical cavity, a water-collecting spherical cavity, and multiple sets of heat exchange tubes. This allows maintenance personnel to enter the spherical cavity through the water inlet and outlet pipes for inspection and leak detection without removing the catalyst. While this solution solves the maintenance difficulties of traditional reactors, it still has the following drawbacks:

[0005] 1. When maintenance personnel need to enter the upper and lower spheres for maintenance, they need to use ropes or ladders to enter the upper and lower spheres. Especially when entering the narrow space of the lower sphere, it is difficult for personnel to stand and they are prone to slipping from the water inlet pipe, which poses a serious safety hazard.

[0006] 2. Due to the small space inside the sphere and poor ventilation, long-term operation can easily lead to oxygen deprivation and stuffiness for maintenance personnel, causing physical discomfort and further increasing operational risks. Summary of the Invention

[0056] The unlocking block 312 is squeezed by the inclined push plate 314 , so that the mountain-shaped rod 310 moves, so that the mountain-shaped rod 310 is disengaged from the upper docking hole 307 , the middle docking hole 308 and the lower docking hole 309 at the same time.

[0057] As an embodiment, the lifting assembly 200 includes a winch 201, a wiring wheel 202 and a vertical track 203.

[0060] The trapezoidal block 315 is squeezed by the inclined block 209, so that the trapezoidal block 315 drives the inclined push plate 314 to squeeze the unlocking block 312, and the unlocking block 312 drives the mountain-shaped rod 310 to move, so that the mountain-shaped rod 310 no longer fixes the insertion block 205, thereby realizing the separation of the lifting assembly 200 and the protective assembly 300.

[0063] By locking the pneumatic rod 405, the L-shaped rod 404 is driven to move, so that the L-shaped rod 404 drives the switching block 406 to move, so that the switching block 406 is inserted into the upper docking hole 307, and thus disengaged from the upper docking hole 307, realizing the docking of the upper moving component 400 with the protective component 300, or the disengagement of the upper moving component 400 with the protective component 300. When the switch 406 is inserted into the docking hole 307, at this time, under the action of the upper screw slide 401, the mountain-shaped rod 310 is reset, so that the mountain-shaped rod 310 is reinserted into the switching hole 407, and the switching realizes the fixing of the moving component 400 and the protective component 300 together.

[0067] Second, when the docking ring 411 is positioned and docked with the protective assembly 300, the blower 409 and the hose 410 cooperate with each other to allow the staff to work in the upper hollow ball 709 or the lower hollow ball 710.

[0069] Since most of the structures in the lower moving assembly 500 are the same as those in the upper moving assembly 400, when working, it is also the same as the upper moving assembly 400. First, it docks with the protection assembly 300 to separate the protection assembly 300 from the lifting assembly 200. After separation, the protection assembly 300 is translated and raised.

[0080] S1. Preparation: First, the worker fixes the vacuum cleaner on the storage plate 304. Then, he or she secures the strap 316 to the body. After the strap is secured, the worker stands on the step 302 and holds the handrail 303.

[0081] S2. Lifting the goods and personnel: Start the winch 201. Under the action of the cable pulley 202, the winch 201 begins to reel in the wire rope 207. The wire rope 207 pulls the lifting arm 204 upward, causing the lifting arm 204 to slide within the vertical track 203. As the lifting arm 204 moves, the protective assembly 300, personnel, and tools are lifted up.

[0082] S3. Unlocking: When the protective assembly 300 moves to the vicinity of the upward assembly 400, one end of the docking tube 411 is first inserted into the through hole 305 and communicates with the hollow tube 301. At the same time, the trapezoidal block 315 contacts the inclined block 209, causing the inclined block 209 to squeeze the trapezoidal block 315. When the top surface of the storage plate 304 contacts the limit ring 412, the winch stops working. At the same time, the trapezoidal block 315 is squeezed by the inclined block 209, causing the mountain-shaped rod 310 to disengage from the locking hole 206. At this time, only the plug block 205 is plugged into the middle docking hole 308 and is not locked. However, the plugging of the docking tube 411 and the hollow tube 301 prevents the protective assembly 300 from being detached from the plug block 205.

[0083] S4. Docking: First, the locking pneumatic rod 405 is activated. When the locking pneumatic rod 405 is in operation, it drives the L-shaped rod 404 to slide inside the disc 403. When the L-shaped rod 404 moves, it also drives the switching block 406 to move toward the upper docking hole 307, so that the switching block 406 is inserted into the upper docking hole 307. At this time, the switching block 406 is not locked and fixedly connected to the protective component 3, and the insert block 205 is not separated from the docking hole 308.

[0084] S5. Conveying lock: Start the upper screw slide 401, that is, the motor drives the internal threaded rod to rotate, thereby driving the downward hydraulic rod 402, the upper docking component and the protective component 300 to move. When the L-shaped rod 404 and the docking pipe 411 move, the square block 306 will be driven to move. When the square block 306 moves, the insert block 205 will be disengaged from the docking hole 307. At the same time, the trapezoidal block 315 will be away from the inclined block 209. At this time, the trapezoidal block 315 will be reset. At the same time, the mountain-shaped rod 310 will also be reset. When the mountain-shaped rod 310 is reset, it will be inserted into the switching hole 407, so that the protective component 300 and the upper moving component 400 are fixed together. When the protective component 300, people and objects are transported to the top of the drain pipe 711, at this time, under the action of the downward hydraulic rod 402, the people, objects and protective component 300 are transported into the upper hollow ball 709, which is convenient for staff to inspect the interior.

[0085] S6. Maintenance: During maintenance, start the blower 409. When the blower 409 is working, it transmits gas to the docking tube 411 through the hose 410. Finally, the gas in the docking tube 411 is transmitted to the hollow tube 301 and blown from the hollow tube 301 to the bottom of the upper hollow ball 709, thereby supplying oxygen to the personnel working inside and reducing the stuffiness inside.

[0086] When inspecting the lower hollow ball 710, the operating steps and docking method are basically the same as those when inspecting the upper hollow ball 709. The difference is that when the lower moving component 500 is docked with the protective component 300, the docking pipe is plugged into the bottom surface of the hollow tube 301, so that the wind blows to the top of the inner cavity of the lower hollow ball 710 through the through hole 305. At the same time, a material receiving component is installed on the surface of the lower moving component 500. The material receiving component is used to receive impurities that fall into the lower hollow ball 710, which is convenient for unified processing later. At the same time, there are also differences during work. When inspecting the upper hollow ball 709, the personnel stand in the upper hollow ball 709, while when inspecting the lower hollow ball 710, the personnel need to stand on the storage plate 304. When cleaning the upper hollow ball, a vacuum cleaner is needed to avoid impurities that are difficult to clean. When cleaning the lower hollow ball 710, there is no need to carry a vacuum cleaner. Only dust or impurities need to be cleaned out from the water inlet pipe 712.

[0087] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
