Abstract
Description
Technical Field
[0001] This invention belongs to the field of slag pond structure technology, specifically a slag pond structure and its manufacturing method. Background Technology
[0002] Coal gasification ash, a byproduct of coal chemical industry, is characterized by high ash content, low calorific value, fine particle size, and environmental pollution when accumulated. Currently, coal gasification ash is typically treated as building material or added to circulating fluidized bed boilers for recombustion, but this method yields very low added value. Therefore, researching technologies for reducing the volume and recycling resources of coal gasification ash is crucial for coal gasification and indirect coal-to-oil enterprises to lower ash treatment costs and achieve both economic and environmental benefits.
[0003] The coal bed in a fixed-bed slag gasifier is stacked high. If the slag discharge casting becomes blocked or the slag discharge is obstructed, the furnace must be shut down. Operators must enter the furnace to clear all the coal and slag layers above the slag pool, exposing the slag pool and the slag discharge casting. The damaged slag discharge casting must be replaced or the blockage cleared before coal can be fed back in and the furnace can be restarted. The whole process is time-consuming, labor-intensive, and also carries a certain degree of danger. Summary of the Invention

[0005] Furthermore, the cooling mechanism also includes: Sewage pipe, which is installed at the bottom of the cooling pool; The inner wall of the cooling pool is uniformly provided with grooves; A liquid extraction assembly is installed on the inner wall of the groove. This assembly is used to spray water from the cooling pool upwards, causing the slag to cool down and solidify rapidly.
[0006] Furthermore, it also includes: The upper slag tank is located above the lower slag tank, and connecting bodies are provided on both sides of the upper slag tank.
[0007] Furthermore, the slag discharge tank mechanism also includes: A conical shell is installed below the outer wall of the slag discharge tank, and the bottom of the conical shell is connected to the top of the operating platform; A temperature regulating pipe is provided, the outer wall of which is fitted into the outer wall of the slag discharge tank. The temperature regulating pipe is installed inside the conical shell and is threaded.
[0008] Furthermore, the slag scraper assembly includes: A rotating plate, one end of which is rotatably connected to the top of the filter box, and a sliding groove is provided on the surface of the rotating plate; The movable block has its outer wall engaged with the inner wall of the slide groove.
[0009] The slag scraper assembly also includes: A connecting rod, the end of which is rotatably connected to the inner wall of the moving block near the rotating plate; The drive device is mounted on the end of the connecting rod away from the moving block; A scraper is installed on the side of the movable block near the filter box, and the outer wall of the scraper is slidably connected to the outer wall of the filter box.
[0010] Furthermore, the liquid extraction assembly includes: A liquid conveying device, wherein the liquid conveying device is installed on the inner wall of the groove; A spray pipe, which is installed at the liquid outlet end of the liquid conveying device; A liquid extraction pipe is installed in the liquid inlet section of a liquid conveying device. Vertical grooves are symmetrically opened at the bottom of the liquid extraction pipe, and a limit ring is provided at the end of the liquid extraction pipe away from the liquid conveying device. A float plate is fitted onto a liquid extraction tube, and a baffle plate is provided on the top of the float plate, the surface of which is in contact with the outer wall of the liquid extraction tube.
[0011] Furthermore, the grinding assembly includes: Telescopic columns are symmetrically arranged on the inner wall of the operating table; The mounting block, the outer wall of which is rotatably connected to one end of the telescopic column; An extrusion member is symmetrically arranged on the inner wall of the mounting block, and the outer wall of the extrusion member is rotatably connected to the inner wall of the mounting block. The extrusion member is configured as a bent rod. A pointed cone, which is positioned above the extruder.
[0012] A method for manufacturing a slag pit structure includes the following steps: A coil is placed inside the slag tank mold, and a heat-conducting material is used to cast a single slag tank unit. Finally, multiple cast slag tank units are assembled into a slag tank. A coil is placed inside the slag sink mold, and the upper and lower parts of the slag sink are cast using heat-conducting material. The upper and lower parts of the slag sink are then connected to form an integral structure. A slag discharge casting is cast using a thermally conductive material in a slag discharge casting mold, and a refractory material is welded onto the bottom surface of the slag discharge casting. Finally, the upper slag pool is attached to the lower slag pool, and the slag discharge casting is installed below the lower slag pool to obtain the slag pool structure.
[0013] The beneficial effects of this invention are as follows: 1. This invention, through the setting of a slag-feeding pool mechanism, when the bottom blockage layer of the slag-feeding pool is thick, the baffle rotates through an external drive and enters the slag-feeding pool from the semi-circular groove in the slag-feeding pool, blocking the bottom of the slag-feeding pool. At this time, the crushing component starts to work, quickly crushing the slag blocks. Then the baffle is opened, allowing the slag-feeding pool to return to normal operation, reducing the burden on the crushing component, and preventing the ash and slag generated by the crushing component from continuously falling down during operation, which would cause the crushing component to rotate less smoothly and affect the crushing efficiency. At the same time, it provides time for the operator to adjust the water temperature in the temperature control pipe. Slightly increasing the water temperature reduces the solidification rate of the slag blocks, making it easier to dynamically control the solidification state of the slag blocks and reduce downtime for cleaning.
[0014] 2. This invention incorporates a cooling mechanism. After the ash and slag enter the cooling pool and solidify upon contact with cold water, they sink to the bottom of the pool. The solid ash and slag are then discharged through a drain pipe via an external slag discharge device. A liquid pumping assembly draws water from the filter box and sprays it out from above, reducing dust dispersion, lowering the temperature difference between the ash and slag and the cooling water, and reducing thermal shock to the equipment. High-temperature ash and slag may clump together during the cooling process, forming large lumps. Spraying water to cool the ash and slag at the height difference reduces their stickiness, keeping them in a looser state. This prevents the internal temperature from becoming too high after the surface of the ash and slag solidifies, which would make discharge difficult and potentially dangerous.
[0015] 3. This invention, by setting up a liquid extraction component, allows water in the cooling pool to be filtered through a filter box. The filtered water is then pumped into the cooling pool through a liquid extraction pipe and subsequently pressurized and sprayed out through a spray pipe. This sprays the water high up, allowing it to contact the ash and slag first, reducing the contact between the fly ash and slag and the inner wall of the cooling pool. This disperses the ash and slag that has accumulated, preventing it from solidifying together and causing the outer surface of the ash and slag to solidify while the internal temperature becomes too high, which could harm other equipment and workers when the ash and slag are discharged.
[0016] 4. By setting up a crushing component, when a thin solidified layer forms at the bottom of the slag pool, causing blockage, the built-in drive of the mounting block drives the extrusion components to rotate and approach each other, so that the cone and extrusion components crush the solidified layer of ash and slag, causing the ash and slag to fall quickly; when the solidified layer of the slag discharge casting at the bottom of the slag pool is thick and blocked, the telescopic column extends, pushes the mounting blocks to approach each other, and drives the mounting blocks to rotate along the axis of the telescopic column, increasing the crushing area of the extrusion components and cones, so as to clean up the solidified ash and slag near the slag discharge casting, expand the crushing space, and quickly clean up even thick solidified layers, so that the slag discharge casting can resume slag discharge.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: a slag pool structure and its manufacturing method are described below.
[0021] include: Cooling mechanism 1, with slag discharge mechanism 2 installed on top of cooling mechanism 1; Slag discharge mechanism 3 is installed on top of slag discharge mechanism 2; During operation, the slag discharge mechanism 3 is installed at the bottom of the gasifier, allowing the slag to be guided into the cooling mechanism 1. When the slag discharge mechanism 3 becomes blocked, the slag discharge mechanism 2 crushes the blocked slag inside the slag discharge mechanism 3, so that the crushed slag forms ash and slag that is quickly discharged. The discharge speed is maintained, and after solidification inside the cooling mechanism 1, the solidified ash and slag are removed using the slag discharge equipment.
[0022] The upper slag tank 4 is located above the lower slag tank 301. In use, the upper slag tank 4 is installed inside the gasifier and abuts above the lower slag tank 301, so that the interfaces of the lower slag tank 301 and the upper slag tank 4 are connected. The slag-loading pool 4 includes multiple slag-loading pool units 41, which are assembled circumferentially to form a conical ring. Connecting bodies 5 are provided on both sides of the slag-loading pool unit 41, and the slag-loading pool units 41 are connected to each other through the connecting bodies 5. The space below the connecting bodies 5 is provided to allow the slag-loading pool 4 to fit closely to the gasifier through the connecting bodies 5, preventing interference with the inner wall structure of the furnace directly opposite. The solid part and the space each occupy approximately half. Each adjacent slag-loading pool unit 41 can be detachably fastened by bolts. The gaps between adjacent slag tank units 41 can be sealed by coating the inner wall of the slag tank 4 with a partition layer, or by stacking refractory bricks inside the slag tank 4 and filling the outside of the slag tank 4 with ramming material to fill the gaps.
[0023] Cooling mechanism 1 includes: Cooling pool 101, the top of cooling pool 101 is connected to the bottom of slag discharge mechanism 2, and cooling pool 101 is connected to a cold water source. The filter box 104 is evenly arranged on the inner wall of the cooling pool 101. The filter box 104 filters the water in the cooling pool 101, so that the liquid pumping component 106 sprays the cold water upward, which first contacts the ash and slag, reducing the ash and slag from scattering inside the cooling pool 101. The slag scraping assembly 105 is symmetrically arranged on both sides of the filter box 104.
[0024] Cooling mechanism 1 also includes: A drain pipe 102 is installed at the bottom of the cooling pool 101, and grooves 103 are evenly provided on the inner wall of the cooling pool 101. The liquid extraction assembly 106 is installed on the inner wall of the groove 103. The liquid extraction assembly 106 is used to spray water in the cooling pool 101 upwards to make the slag block cool down and solidify quickly.
[0025] After the ash and slag enter the cooling tank 101, they solidify upon contact with cold water and sink to the bottom of the cooling tank 101. The solid ash and slag are removed by an external slag discharge device. The liquid pumping component 106 pumps water from the filter box 104 and sprays it out from the top to reduce dust scattering, reduce the temperature difference between the ash and slag and the cooling water, and reduce the thermal shock to the equipment. High-temperature ash and slag may stick together during the cooling process, forming large lumps. Spraying water to cool the ash and slag in the middle of the height difference can reduce the stickiness of the ash and slag, keeping it in a relatively loose state. This avoids the internal temperature of the ash and slag becoming too high after the surface of the ash and slag solidifies, which would make it difficult to discharge and could easily cause danger.
[0026] Slag removal mechanism 2 includes: The top of the operating platform 201 is connected to the bottom of the slag discharge tank 301, and the bottom of the operating platform 201 is connected to the top of the cooling tank 101. The grinding component 202 is symmetrically arranged on the inner wall of the operating table 201, and the outer wall of the grinding component 202 is in contact with the inner wall of the operating table 201.
[0027] High-temperature ash and slag in the gasifier enter the cooling box through the slag discharge pool 301. When the temperature in the slag discharge pool 301 drops sharply, the ash and slag will solidify rapidly, thus blocking the slag discharge casting at the bottom of the slag discharge pool 301. At this time, the crushing component 202 is activated to crush the ash and slag blocking the slag discharge casting, causing the ash and slag to fall into the cooling pool 101. This prevents the ash and slag from blocking the slag in the gasifier and preventing the slag blocks in the gasifier from being discharged in time, which would increase the pressure in the furnace. The small amount of solidified ash and slag is simply sheared. When the slag discharge casting accumulates a thick layer of ash and slag, it indicates that the temperature of the slag discharge pool 301 is not suitable, causing the ash and slag to solidify prematurely. At this time, the crushing component 202 rotates to expand the crushing range, so that the ash and slag can be discharged quickly, helping the workers to judge the cooling temperature of the slag discharge pool 301.
[0028] The slag discharge tank mechanism 3 includes: Slag discharge tank 301 is installed on the top of operating platform 201, and a semi-circular groove 302 is provided in the middle of slag discharge tank 301. Baffle 303, the outer wall of baffle 303 is rotatably connected to the inner wall of semicircular groove 302, and the surface of baffle 303 is in contact with the inner wall of semicircular groove 302.
[0029] The slag discharge tank mechanism 3 also includes: Conical shell 304 is installed below the outer wall of slag discharge tank 301, and the bottom of conical shell 304 is connected to the top of operating platform 201. Temperature regulating pipe 305, the outer wall of temperature regulating pipe 305 is sleeved with the outer wall of slag tank 301, temperature regulating pipe 305 is installed inside conical shell 304, temperature regulating pipe 305 is connected to water source, and temperature regulating pipe is set in thread shape.
[0030] After the slag collection tank 301 is connected to the bottom of the gasifier, the baffle 303 is in the open state. The slag blocks pass through the slag collection tank 301 into the cooling tank 101. The water source in the temperature regulating pipe 305 cools the surface of the slag collection tank 301. When the blockage layer at the bottom of the slag collection tank 301 is thick, the baffle 303 is rotated by an external drive and enters the slag collection tank 301 from the semi-circular groove 302, blocking the bottom of the slag collection tank 301. At this time, the crushing component 202 begins to operate. After quickly crushing the slag, the baffle 303 is opened to allow the slag tank 301 to resume normal operation, reducing the burden on the crushing component 202 and preventing the ash and slag generated by the crushing component 202 from falling continuously during operation, which would cause the crushing component 202 to rotate less smoothly and affect the crushing efficiency. At the same time, it provides time for the staff to adjust the water temperature in the temperature control pipe 305, increase the water temperature, reduce the solidification rate of the slag, facilitate dynamic control of the solidification state of the slag, and reduce downtime for cleaning.
[0031] Example 2, please refer to Figures 1-10 The present invention provides a technical solution: based on embodiment 1, the slag scraping assembly 105 includes: The rotating plate 1051 has one end rotatably connected to the top of the filter box 104. The surface of the rotating plate 1051 is provided with a sliding groove 1056. When the scraper 1055 is above, the rotating plate 1051 is tilted on both sides of the filter box 104 to block the ash and slag falling from above. The outer wall of the movable block 1052 is engaged with the inner wall of the slide 1056.
[0032] The slag scraper assembly 105 also includes: Link 1053, the end of link 1053 near the rotating plate is rotatably connected to the inner wall of moving block 1052; The drive device 1054 is configured as a motor and is installed on the end of the connecting rod 1053 away from the moving block 1052. The scraper 1055 is installed on the side of the movable block 1052 near the filter box 104, and the outer wall of the scraper 1055 is slidably connected to the outer wall of the filter box 104.
[0033] When the filter box 104 filters the water in the cooling pool 101, fly ash easily adheres to the filter holes of the filter box 104. At this time, the drive device 1054 drives the connecting rod 1053 to move up and down, causing the moving block 1052 to drive the scraper 1055 to move downward. During the downward movement of the scraper 1055, the rotating plate 1051 is moved to the side closer to the filter box 104, so that the rotating plate 1051 rotates to the vertical position during the downward movement of the scraper 1055, keeping the filter box 104 in use and providing a continuous water flow to the liquid pumping assembly 106 to maintain the cooling effect in the cooling pool 101.
[0034] Liquid extraction assembly 106 includes: Liquid conveying device 1061 is installed on the inner wall of groove 103; The spray pipe 1062 is installed at the outlet end of the liquid conveying device 1061; The liquid extraction pipe 1067 is installed at the liquid inlet end of the liquid conveying device 1061. Vertical grooves 1063 are symmetrically opened at the bottom of the liquid extraction pipe 1067. A limit ring 1066 is provided at the end of the liquid extraction pipe 1067 away from the liquid conveying device 1061. A float plate 1064 is fitted onto a liquid extraction pipe 1067. A baffle plate 1065 is symmetrically arranged on the top of the float plate 1064. The surface of the baffle plate 1065 is in contact with the outer wall of the liquid extraction pipe 1067. The float plate 1064 moves up and down along the liquid extraction pipe 1067 following the liquid surface, so that the baffle plate 1065 blocks the vertical groove 1063 on the liquid extraction pipe 1067, thereby expanding the water inlet area of the liquid extraction pipe 1067, making the water inlet pipe smoother, and maintaining the water output.
[0035] After being filtered by the filter box 104, the water in the cooling pool 101 is drawn in by the liquid conveying device 1061, which is a water pump. The water is then pressurized and sprayed out from the spray pipe 1062, causing the spray pipe 1062 to spray the water high. The water first comes into contact with the ash and slag, reducing the contact between the fly ash and the inner wall of the cooling pool 101. This disperses the ash and slag that has gathered together, preventing the ash and slag from solidifying together. This would cause the outside of the ash and slag to solidify while the internal temperature is too high, which could cause injury to other equipment and workers when the ash and slag are discharged.
[0036] The grinding component 202 includes: Telescopic columns 2021 are symmetrically arranged on the inner wall of the operating table 201; Mounting block 2022, the outer wall of mounting block 2022 is rotatably connected to one end of telescopic column 2021; The extrusion component 2023 is symmetrically arranged on the inner wall of the mounting block 2022. The outer wall of the extrusion component 2023 is rotatably connected to the inner wall of the mounting block 2022. The extrusion component 2023 is configured as a bent rod. The pointed cone 2024 is evenly arranged above the extruder 2023.
[0037] Initially, the telescopic column 2021 is fully retracted inside the operating table 201, and the extrusion component 2023 contacts the inner wall of the slag discharge casting at the bottom of the slag pool 301. When a thin solidified layer forms at the bottom of the slag pool 301, causing blockage, the built-in drive of the mounting block 2022 drives the extrusion component 2023 to rotate and move closer to each other, so that the cone 2024 and the extrusion component 2023 break the solidified layer of ash and slag, causing the ash and slag to fall quickly. When the solidified layer of the slag discharge casting at the bottom of the slag discharge pool 301 is thick and blocked, the telescopic column 2021 extends, pushes the mounting blocks 2022 closer to each other, and drives the mounting blocks 2022 to rotate along the axis of the telescopic column 2021, increasing the crushing area of the extrusion piece 2023 and the spikes, so as to clean up the solidified ash near the slag discharge casting, expand the crushing space, and quickly clean up the thick solidified layer, so that the slag discharge casting can resume slag discharge.
[0038] A method for manufacturing a slag pit structure includes the following steps: A coil is placed inside the slag pool mold, and a heat-conducting material is used to cast a slag pool unit 41. Finally, multiple cast slag pool units 41 are assembled into a slag pool 4. A coil is placed inside the slag sink mold, and the upper and lower parts of the slag sink 301 are cast using heat-conducting material. The upper and lower parts of the slag sink 301 are then connected to form an integral structure. A slag discharge casting is cast using a thermally conductive material in a slag discharge casting mold, and a refractory material is welded onto the bottom surface of the slag discharge casting. Finally, the upper slag pool 4 is abutted against the lower slag pool 301, and the slag discharge casting is installed below the lower slag pool 301 to obtain the slag pool structure.
[0039] The slag pool 4 is cast using thermally conductive material. A coil is placed inside the slag pool mold and then cast into a single slag pool unit 41. Multiple cast slag pool units 41 are assembled to form a conical ring. The gaps between adjacent slag pool units 41 are sealed by coating the inner wall with a partition layer. The slag discharge pool 301 is cast using thermally conductive material. Similarly, a coil is placed inside the slag discharge pool mold before casting. The slag discharge pool 301 includes a detachable upper part and a lower part, both of which are conical in shape. The connecting short section is an integrally formed structure. A slag discharge casting is provided at the bottom of the slag discharge pool 301, and refractory material is welded to the bottom surface of the slag discharge casting. During installation, the upper slag pool 4 is placed against the top surface of the lower slag pool 301, and the slag discharge casting is installed below the lower slag pool 301.
[0040] The specific workflow is as follows: During operation, after the slag discharge tank 301 is connected to the bottom of the gasifier, the baffle 303 is in the open state. The slag blocks pass through the slag discharge tank 301 into the cooling tank 101. The water source in the temperature regulating pipe 305 cools the surface of the slag discharge tank 301. The high-temperature ash and slag in the gasifier enter the cooling tank through the slag discharge tank 301. When the temperature in the slag discharge tank 301 drops sharply, the ash and slag will solidify rapidly, thus blocking the slag discharge casting at the bottom of the slag discharge tank 301. At this time, the crushing component 202 is activated to discharge the slag. The ash and slag blocking the casting are crushed, causing them to fall into the cooling pool 101. This prevents the ash and slag from clogging the gasifier and causing the slag to be unable to be discharged in time, which would increase the pressure inside the furnace. Small amounts of solidified ash and slag are simply sheared. When a thick layer of ash and slag accumulates on the slag discharge casting, it indicates that the temperature of the slag discharge pool 301 is not suitable, causing the ash and slag to solidify prematurely. At this time, the crushing component 202 rotates to expand the crushing range and allow the ash and slag to be discharged quickly. Then the baffle 303 is opened to restore the slag discharge pool 301 to normal operation. After the ash enters the cooling tank 101, it solidifies upon contact with cold water and sinks to the bottom of the cooling tank 101. The solid ash is removed by an external slag discharge device. The liquid pumping component 106 pumps water from the filter box 104 and sprays it out from above to reduce dust scattering, reduce the temperature difference between the ash and the cooling water, and reduce the thermal shock to the equipment. High-temperature ash may stick together during the cooling process, forming large lumps. Spraying water to cool the ash in the middle of the height difference can reduce the stickiness of the ash and keep it in a relatively loose state. After the ash cools, the solidified ash is removed by the slag discharge device.
