A slag pool for uniformly cooling slag gasification furnace

Abstract

This invention discloses a uniformly cooled slag pool for a slag gasification furnace, comprising a quench chamber and a slag pool, wherein the slag pool is located at the bottom of the quench chamber. This invention relates to the field of slag pool technology for gasification furnaces. This uniformly cooled slag pool for a slag gasification furnace, by incorporating a cooling mechanism, a labor-saving assembly mechanism, and a slag collection mechanism between the quench chamber and the slag pool, allows the device to achieve uniform cooling through the coordinated operation of these mechanisms. The spiral cooling pipes surround the slag pool, and the heat exchange with the coolant inside the spiral cooling pipes results in uniform cooling. This effectively prevents heat accumulation from molten slag and iron in the annular slag pool, maintaining a relatively low and constant temperature on the inner surface of the slag pool. This reduces the erosion and corrosion of the slag pool metal caused by minerals in the molten slag due to temperature increases.

Description

Technical Field

[0001] This invention relates to the field of gasification slag pool technology, specifically to a slag gasification slag pool with uniformly cooled distribution. Background Technology

[0002] As a key technology for the efficient utilization of coal and other carbonaceous fuels, pulverized coal slag gasification technology's core equipment is the pulverized coal slag gasifier. This gasifier typically comprises a cylindrical coal gasification pressure vessel, i.e., the pulverized coal slag gasifier shell. During the gasification process, coal or other carbonaceous fuels are fed from the top of the coal gasification pressure vessel, while oxygen and steam from outside the furnace are introduced into the fuel inside the lower part of the pressure vessel through tuyeres (nozzles). The gasification reaction is completed under high temperature and high pressure. The residual ash produced by the gasification reaction, mainly slag and iron, settles and collects in a slag pool at the bottom of the coal gasification pressure vessel. Subsequently, it is intermittently discharged in liquid form through the slag discharge port of the slag pool, a process commonly known in the industry as "liquid slag discharge." The discharged slag and iron enter the water in the quench chamber at the bottom of the slag pool for quenching.

[0003] The slag pool is a core component in a pulverized coal slag gasifier that receives and discharges molten slag and iron. Its operational stability directly determines the gasifier's continuous operation capability. However, in actual operation, the slag pool faces a harsh service environment: on the one hand, it must continuously receive high-temperature (usually molten) slag and iron, and withstand severe thermal shock; on the other hand, the minerals and iron components in the high-temperature slag will also cause severe erosion and corrosion to the slag pool material. Especially during the alternation of slag collection and slag discharge operations, the high-temperature and flow characteristics of the slag and iron will further exacerbate the erosion and thermal shock damage to the slag pool.

[0004] In existing technologies, the slag pools of pulverized coal slag gasifiers generally lack a scientifically sound and uniform cooling mechanism. This leads to the slag pool components being prone to burn-out due to heat accumulation, which can even cause blockage of the slag discharge port in severe cases. This forces the gasifier to shut down for maintenance and significantly shortens the service life of the slag pool. Frequent damage requires maintenance or disassembly and replacement by staff, but the existing structural design of the slag pool makes maintenance and disassembly extremely inconvenient. In addition, frequent shutdowns for maintenance not only increase maintenance costs but also cause huge losses due to downtime, seriously affecting the continuity and stability of gasifier operation and restricting the extension of the gasifier's operating cycle.

[0005] To avoid the aforementioned problems, a slag gasification furnace slag pool with uniform cooling distribution is proposed to solve the existing problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a slag pool for a slag gasifier with uniformly distributed cooling. This solves the problem that the lack of a uniform cooling mechanism in the device leads to the slag pool components being easily burned due to heat accumulation, causing blockage of the slag discharge port. It also solves the problem that the service life of the slag pool is significantly shortened due to forced shutdowns for maintenance of the gasifier. Furthermore, it solves the problem that the lack of a convenient disassembly and assembly mechanism makes the device inconvenient to repair and replace, resulting in long downtime for each operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a slag pool for uniformly cooling slag gasification furnace, comprising a quench chamber and a slag pool, wherein the slag pool is located at the bottom of the quench chamber, a feed pipe is connected to the bottom of the slag pool, a water inlet pipe is connected to the front side of the slag pool, a water outlet pipe is connected to the rear side of the slag pool, a cooling mechanism is provided on the surface of the slag pool, a labor-saving assembly mechanism adapted to the cooling mechanism is provided on the surface of the slag pool, and a slag collection mechanism is provided inside the slag pool.

A spiral cooling pipe is installed between the second spiral groove and the first spiral groove. A plurality of assembly holes are formed on the surface of both the outer arc assembly plate and the slag pool, and two adjacent assembly holes are fixedly connected by bolts.

[0009] Preferably, the labor-saving assembly mechanism includes two inclined frames, which are fixedly connected to both sides of the spiral cooling pipe. Inclined insertion holes are provided on both sides of the slag pool. Through openings are provided on the surface of the inclined frames. Arc-shaped sliding grooves are provided on both sides of the slag pool, and these grooves communicate with the inclined insertion holes. An arc-shaped sliding plate, adapted to the through opening, is slidably connected inside the arc-shaped sliding groove. A guide slider is fixedly connected to the top of the outer arc assembly plate. Guide grooves, slidably adapted to the guide slider, are provided on both sides of the slag pool.

[0010] Preferably, the slag collection mechanism includes a ring frame, which is fixedly installed inside the slag pool, and the surface of the ring frame is connected to the water inlet pipe through a pipe. A rotating cylinder is rotatably connected to the outlet at the bottom of the quench chamber, and the outer wall of the rotating cylinder is rotatably connected to the ring frame. Several movable plates are fixedly connected at equal intervals around the surface of the rotating cylinder. Several drainage holes are opened at the bottom of the ring frame, and several water-dispelling blades are fixedly connected to the bottom of the rotating cylinder.

[0011] Preferably, a water level line is provided inside the slag pool and at the bottom of the ring frame.

[0012] Preferably, the surface of the slag pool is provided with a groove adapted to the arc-shaped sliding plate, and the top of the outer arc assembly plate is fixedly connected with an inclined plate adapted to the arc-shaped sliding plate.

[0013] Preferably, the surface of the feed tube is provided with an external thread, and the surface of the external thread is threaded with a threaded sleeve.

[0014] Preferably, the threaded sleeve is rotatably connected to an inner conical ring sleeve.

[0015] Preferably, the slag pool has fitting holes on both sides, and two fitting holes are arranged vertically on the same side. The inner wall of the outer arc assembly plate is fixedly connected with a fitting plate that matches the fitting hole.

[0016] Preferably, the inner wall of the outer arc assembly plate is provided with a receiving groove adapted to the inclined frame.

[0017] This invention provides a slag pool for a slag gasification furnace with uniformly cooled slag. Compared with existing technologies, it has the following advantages:

[0018] This invention provides a uniformly cooled slag pool for a slag gasification furnace. By setting a cooling mechanism, a labor-saving assembly mechanism, and a slag collection mechanism between the quench chamber and the slag pool, the device can achieve uniform cooling through the coordinated operation of these mechanisms. This is achieved via heat exchange between the spiral cooling pipes surrounding the slag pool and the coolant inside the spiral cooling pipes, effectively preventing heat accumulation from molten slag and iron in the slag pool. This keeps the temperature of the inner surface of the slag pool relatively low and constant, reducing the erosion and corrosion of the slag pool metal by minerals in the molten slag caused by temperature increases. Secondly, the cooling mechanism allows for the disassembly and assembly of the spiral cooling pipes, avoiding inconvenience for subsequent maintenance and replacement. The labor-saving assembly mechanism facilitates the assembly of the cooling mechanism, improving ease of assembly and reducing assembly time. Finally, the slag collection mechanism allows the water source inside the slag pool to be slowly centrifugally driven, causing the slag inside the slag pool to settle centrally and preventing slag residue from remaining on the inclined inner wall of the slag pool.

[0019] The present invention provides a slag gasification furnace slag pool with uniform cooling distribution. By setting an external thread, a threaded sleeve and an inner conical ring sleeve on the surface of the feed pipe, the two outer arc assembly plates can be assembled together, which facilitates the cooperation and locking of the above-mentioned mechanisms and ensures the precision of the assembly.

[0020] The present invention provides a slag pool for uniformly cooling slag gasification furnace. By setting a groove and an inclined plate between the slag pool and the outer arc assembly plate, the inclined plate can be easily positioned by the groove, thus avoiding the problem of random displacement of the arc sliding plate during the use of the slag pool.

[0021] The present invention provides a slag pool for uniformly cooling slag gasification furnace. By setting a first spiral groove and a second spiral groove between the slag pool and the outer arc assembly plate, the spiral cooling pipes buried on the surface of the slag pool can be in close contact with the slag pool, increasing the heat transfer area and improving the bonding between the spiral cooling pipes and the slag pool. This enhances the cooling effect, eliminates the possibility of annular slag pool component cracking caused by cooling, ensures heat transfer effect and guarantees the durability of castings, and extends the service life of the slag pool.

[0049] In a preferred embodiment, to facilitate labor-saving assembly of the outer arc assembly plate 601 and the spiral cooling pipe 604, the surface of the slag pool 2 is provided with a labor-saving assembly mechanism 7 adapted to the cooling mechanism 6.

[0050] In a preferred embodiment, to prevent slag from falling onto the inclined inner wall of the slag pool 2, a slag collection mechanism 8 is provided inside the slag pool 2. The slag collection mechanism 8 includes a ring frame 801, which is fixedly installed inside the slag pool 2. The surface of the ring frame 801 is connected to the water inlet pipe 4 through a pipe. A rotating cylinder 802 is rotatably connected to the outlet at the bottom of the quench chamber 1, and the outer wall of the rotating cylinder 802 is rotatably connected to the ring frame 801. Several movable plates 803 are fixedly connected at equal intervals around the surface of the rotating cylinder 802. Several drainage holes 804 are provided at the bottom of the ring frame 801. Several water-dispelling blades 805 are fixedly connected to the bottom of the rotating drum 802. A water level line 11 is provided inside the slag pool 2 and at the bottom of the ring frame 801. A high-temperature resistant sealed bearing, model UC208 high-temperature resistant type, is provided at the rotating connection between the rotating drum 802 and the quench chamber 1 and the ring frame 801. It is equipped with a mechanical seal to effectively prevent the leakage of high-temperature water vapor and gas. At the same time, the outer ring of the bearing is coated with a wear-resistant ceramic coating to improve wear resistance.

[0051] The surface of the slag pool 2 is provided with a groove 9 that is compatible with the arc-shaped sliding plate 705, and the top of the outer arc mounting plate 601 is fixedly connected with an inclined plate 10 that is compatible with the arc-shaped sliding plate 705.

[0052] The advantage of Example 2 compared to Example 1 is that by setting a groove 9 and an inclined plate 10 between the slag pool 2 and the outer arc assembly plate 601, the inclined plate 10 can easily position the arc-shaped sliding plate 705 through the groove 9, thus avoiding the problem of the arc-shaped sliding plate 705 shifting randomly during the use of the slag pool 2.

[0053] The specific usage steps are as follows:

[0054] Segmented assembly: First, the spiral cooling tube 604 is gripped by the inclined frame 701, causing the spiral cooling tube 604 to be fitted from bottom to top into the first spiral groove 602 on the surface of the slag pool 2. When the spiral cooling tube 604 is embedded in the first spiral groove 602, the inclined frame 701 will enter the interior of the inclined insertion hole 702. Then, the arc-shaped sliding plate 705 is moved at the groove 9, causing the arc-shaped sliding plate 705 to penetrate into the through hole 703 inside the inclined frame 701, providing temporary suspension for the spiral cooling tube 604.

[0055] Subsequently, guided by the sliding guide slider 706 and the guide groove 707, the two outer arc assembly plates 601 are slid laterally to fit against the surface of the slag pool 2, causing the second spiral groove 603 on the inner wall of the outer arc assembly plate 601 to fit into the outer surface of the spiral cooling pipe 604. Correspondingly, the receiving inclined groove 17 inside the outer arc assembly plate 601 will coincide with the inclined frame 701. When the outer arc assembly plate 601 moves laterally with the guide slider 706, the outer arc assembly plate 601 simultaneously carries the inclined plate 10 into the interior of the groove 9. After the inclined plate 10 enters the interior of the groove 9, the inclined surface of the inclined plate 10 will lock onto the handle of the arc-shaped sliding plate 705.

[0056] Then, screw the threaded sleeve 13 on the surface of the external threaded part 12 to cause the threaded sleeve 13 to drive the inner conical ring sleeve 14 to rise. The rise of the inner conical ring sleeve 14 will tighten the bottom ends of the two outer arc assembly plates 601. Finally, the outer arc assembly plates 601 and the slag pool 2 can be fixed by the assembly hole 605 and the bolt 606.

[0057] Slag centering: Water is injected into the ring frame 801 through the water inlet pipe 4. The water flow will drive several movable plates 803 to rotate, and finally inject water into the slag pool 2 through the drain hole 804. The water level in the slag pool 2 is always higher than the bottom outlet of the quench chamber 1, and the water level is maintained at the water level line 11. When the water flow drives the movable plates 803 and the rotating drum 802 to rotate, the rotating drum 802 drives several water-dispelling blades 805 to stir in the water, so that the slag entering the slag pool 2 from the quench chamber 1 can be centered in the center of the slag pool 2 according to the water pressure. When water is flowing into the slag pool 2, the cooling equipment needs to be connected to the port of the spiral cooling pipe 604 in advance, so that the coolant is continuously supplied into the spiral cooling pipe 604, thereby cooling the slag pool 2 in a countercurrent manner and maintaining the cooling condition inside the slag pool 2.
