Description

Technical Field

[0001] This utility model belongs to the field of energy and chemical technology, and in particular relates to an easily replaceable modular anti-wear component for a quench chamber. Background Technology

[0002] Gasifiers are core equipment in the energy, chemical and environmental protection fields. The quench chamber of the gasifier is located below the reaction section of the gasifier. It is a critical piece of equipment with an extremely harsh working environment. The study of particle movement and erosion damage inside the quench chamber relies on advanced CFD simulation and experimental verification. Scaling in the quench chamber is a very common and difficult problem. It directly affects the long-term stable operation, economic benefits and safety of the gasification unit. Scaling can lead to quench chamber blockage, increased pressure differential, decreased gasification efficiency and even forced unplanned shutdown.

[0003] A search revealed that publication number CN206970549U, with an application date of June 8, 2017, discloses a gasifier anti-ash accumulation quench chamber, comprising a quench chamber shell, a downcomer, an upcomer, a baffle, and a spray assembly. All components are installed inside the quench chamber shell. The spray assembly includes a spray ring pipe and a connector for fixing the spray ring pipe to the quench water inlet pipe. The spray ring pipe is connected to the quench water inlet pipe through a connecting pipe. The spray ring pipe is arranged around the outer periphery of the upcomer and has at least three rows of nozzles. Each row of nozzles is arranged parallel to the central axis of the spray ring pipe. These three rows of nozzles are the middle row nozzles, the outer row nozzles, and the inner row nozzles. The middle row nozzles are arranged vertically downwards, the outer row nozzles are arranged inclined outwards, and the inner row nozzles are arranged inclined inwards.

[0004] However, it still has the following drawbacks in practical use: The downcomers in the existing quench chamber are subjected to erosion pressure for a long time, resulting in severe wear. Replacing them entirely would waste resources, and the disassembly and assembly would be cumbersome, time-consuming, labor-intensive, and inefficient. 2. Existing quench chambers often accumulate scale on their inner walls, affecting heat transfer efficiency and clogging the slag discharge port. Manual cleaning increases labor intensity and reduces cleaning effectiveness and efficiency. Therefore, we provide an easily replaceable modular anti-wear component for the quench chamber to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an easily replaceable modular anti-wear component for a quench chamber. By setting a downcomer tube, the lower section tube is installed at the bottom of the middle section tube under the action of bolts and threads, which facilitates the quick disassembly and assembly of the lower section tube by the staff. The modular design allows for quick disassembly and replacement of worn parts, reducing resource waste. In addition, by using the adjustment component, the height of the annular tube and the nozzle can be adjusted by the motor operation, thereby enabling comprehensive cleaning of dirt adhering to the inner wall of the quench chamber shell, with good cleaning effect and high efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an easily replaceable modular anti-wear component for a quench chamber, including a quench chamber shell and a protective cover installed on its top. A downcomer is provided at the center of the top of the quench chamber shell, and an adjustment component is provided inside the quench chamber shell. The downcomer is composed of an upper section, a middle section, and a lower section. A fourth flange is fixed to the top of the outer wall of the lower section, and a threaded groove is provided at the center of the top of the lower section. The adjustment assembly includes a bracket mounted on top of the quench chamber housing and a motor mounted inside the bracket, with a gear plate mounted on the motor's output shaft.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0024] Please see Figures 1 to 3 This utility model is an easily replaceable modular anti-wear component for a quench chamber, including a quench chamber shell 100 and a protective cover 102 installed on its top. A downcomer 200 is provided at the center of the top of the quench chamber shell 100. The downcomer 200 is composed of an upper section pipe 201, a middle section pipe 202 and a lower section pipe 203. A fourth flange 203a is fixed at the top of the outer wall of the lower section pipe 203, and a threaded groove 203b is provided at the center of the top of the lower section pipe 203.

[0025] Specifically, a slag discharge pipe 101 is provided at the bottom center of the quench chamber shell 100, and a riser pipe 103 is installed on the inner wall of the quench chamber shell 100; a first flange 201a is fixed to the bottom of the outer wall of the upper section pipe 201, and a second flange 202a and a third flange 202b are fixed to the top and bottom of the outer wall of the middle section pipe 202, respectively; the first flange 201a and the second flange 202a, as well as the third flange 202b and the fourth flange 203a are all fixedly connected by bolts 204, and the bottom end of the middle section pipe 202 is spirally sleeved inside the threaded groove 203b.

[0026] Furthermore, the quench chamber shell 100 is located below the gasifier reaction section. The protective cover 102 is used to protect the internal regulating components 300 and facilitate manual maintenance of internal components. The downcomer 200 is divided into three parts: the upper section 201, the middle section 202, and the lower section 203. The lower section 203 is the part most affected by particle impact. The lower section 203 can be quickly disassembled and replaced to improve efficiency and reduce resource waste. The middle section 202 and the lower section 203 are connected by threads and bolts 204 to improve connection strength and stability.

[0027] The operation process of this embodiment is as follows: During use, the quench chamber shell 100 is located below the gasifier reaction section. The high-temperature syngas exiting the gasifier, carrying a large amount of molten slag, directly enters the water bath of the quench chamber shell 100. The syngas and water undergo intense direct contact heat exchange, and the temperature is instantly (within a few seconds) reduced to a saturation temperature slightly above the boiling point of water (approximately 200-250°C). This process "quenches" all chemical reactions, prevents the regeneration of harmful substances, and causes the molten slag to solidify into glassy slag particles. The washing effect of the quench water can effectively remove most of the solid particles (ash, unreacted carbon particles) and some soluble gases (such as HCl, NH3, etc.) from the syngas, achieving a preliminary purification effect. However, in the quench chamber, the movement of particles (including solidified slag particles and unreacted carbon particles) is very complex, and the solid particles will affect the material surface. To prevent mechanical wear and ensure the long-term safe and stable operation of the unit and avoid unplanned shutdowns and serious accidents, the downcomer 200 needs to be disassembled and replaced periodically. The part of the downcomer 200 that suffers the most severe impact wear is the lower section 203. Therefore, when disassembling and replacing the lower section 203, the staff enters the interior through the inspection door on the quench chamber shell 100, removes the bolts 204 used to fix the connection between the third flange and the fourth flange 203a, and then rotates the lower section 203 under the action of the thread to remove it and replace it. The same principle applies to installation. First, the lower section 203 is screwed to the bottom of the middle section 202 under the action of the thread, and then the bolts 204 are used to further fix the connection to improve stability. At the same time, it is convenient for the staff to quickly disassemble and install the lower section 203. The modular design allows for quick disassembly and replacement of worn parts, reducing resource waste. Example 2

[0028] Please see Figure 2 , Figure 4 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that an adjustment component 300 is provided. The adjustment component 300 includes a bracket 301 installed on the top of the quench chamber shell 100 and a motor 302 installed inside the bracket 301. A gear disc 302a is installed on the output shaft of the motor 302. This solves the problem that scale will form on the inner wall of the existing quench chamber, affecting the heat conduction efficiency and blocking the slag discharge port. Manual cleaning will increase the workload and affect the cleaning effect and efficiency.

[0029] Specifically, a first toothed ring 303a meshes with the outer side of the toothed disc 302a, the outer wall of the first toothed ring 303a is fixed to the inner wall of the L-shaped ring 303, and a second toothed ring 303b is fixed to the upper surface of the L-shaped ring 303; the second toothed ring 303b is rotatably mounted on the top of the quench chamber shell 100, and a conical wheel 304 is evenly spaced meshing with the upper part of the second toothed ring 303b along the circumferential direction, and a rotating shaft 304a is installed at the center of the outer wall of the conical wheel 304; the rotating shaft 304a... The other end of 4a passes through the bearing on the U-shaped frame 308 and is connected to the bearing on the inner wall of the U-shaped frame 308. A take-up roller 305 is sleeved on the outer wall of the rotating shaft 304a, and a connecting rope 306 is wound on the outer wall of the take-up roller 305. The other end of the connecting rope 306 passes through the outer shell 100 of the quench chamber and is connected to the collar 306a. An annular tube 307 is provided inside the collar 306a, and nozzles 307a are evenly spaced along the circumference on the outer wall of the annular tube 307.

[0030] Furthermore, the toothed disc 302a meshes with the first toothed ring 303a, and the second toothed ring 303b meshes with the conical wheel 304, which serves as a transmission mechanism. The second toothed ring 303b and the first toothed ring 303a are both located on the L-shaped ring 303, and the three move synchronously. By controlling the forward and reverse rotation of the motor 302, the release and rewinding of the connecting rope 306 are adjusted to change the height of the annular tube 307 and the nozzle 307a.

[0031] The operation process of this embodiment is as follows: When the quench chamber shell 100 is in operation for a long time, the motor 302 is started. The output shaft of the motor 302 rotates, driving the gear disk 302a to rotate. The gear disk 302a meshes with the first gear ring 303a, so the rotation of the gear disk 302a will drive the first gear ring 303a to rotate. The first gear ring 303a and the second gear ring 303b are both fixed on the L-shaped ring 303, and the L-shaped ring 303 is rotatably mounted on the top of the quench chamber shell 100. Therefore, the rotation of the first gear ring 303a will drive the second gear ring 303b to rotate synchronously under the action of the L-shaped ring 303. The second gear ring 303b meshes with the conical wheel 304, so the rotation of the second gear ring 303b will drive the conical wheel 304 to rotate synchronously. The conical wheel 304 rotates... The rotating shaft 304a and the take-up roller 305 on its outer wall are rotated, thereby releasing the connecting rope 306 on its outer wall. As the connecting rope 306 is released, the height of the annular tube 307 and the nozzle 307a is continuously reduced. Then, high-pressure quench water is introduced into the annular tube 307 and sprayed out by the nozzle 307a to impact the inner wall of the quench chamber shell 100, thereby cleaning the dirt attached to the inner wall of the quench chamber shell 100 in a comprehensive manner. The cleaning effect is good and the efficiency is high. When it is necessary to raise and adjust the height of the annular tube 307 and the nozzle 307a, the motor 302 is run, so that its output shaft and the gear disk 302a rotate in opposite directions, thereby winding the connecting rope 306 on the outer wall of the take-up roller 305, so as to raise the height of the annular tube 307 and the nozzle 307a.
