Description

Technical Field

[0001] This utility model relates to the field of hazardous waste renewable material resource utilization and harmless treatment technology, specifically, to a treatment system for hazardous waste renewable materials and carbon-containing materials. Background Technology

[0002] In related technologies, rotary kilns, as well as various gasification furnace technologies such as fixed bed, moving bed, fluidized bed, and entrained flow bed are widely used to incinerate or pyrolyze and gasify hazardous waste and other wastes, and to synergistically process carbonaceous materials such as coal with hazardous waste and other wastes for resource utilization to produce syngas.

[0003] However, when using rotary kilns, coal-fired or gas-fired or electric or plasma-fired high-temperature slag furnaces to incinerate, pyrolyze, or gasify hazardous waste and other wastes, it is unavoidable to generate secondary hazardous waste such as fly ash and slag carrying dioxins and other organic matter and trace amounts of heavy metal pollutants. The harmless landfilling of these secondary hazardous wastes is not only complex and costly, but also poses a risk of pollution to land, water bodies, and the environment. Furthermore, the syngas produced by using various gasification furnace technologies to pyrolyze and gasify carbonaceous materials such as coal and hazardous waste for co-resource recovery only contains carbon monoxide (CO) and hydrogen. The pyrolysis gasification process involves long physical and chemical reactions, high consumption, and limitations imposed by downstream equipment. The high-temperature or ultra-high-temperature syngas produced by the pyrolysis gasification process requires quenching with ambient temperature circulating water or low-temperature syngas before exiting the furnace, resulting in only low-temperature crude syngas discharged at 200-500°C (except for the 900°C of the Shell SHELL furnace). This leads to high investment and operating costs for the long-process equipment, low thermal efficiency, and significant waste due to the partial low-end utilization of high-grade chemically structured raw materials.

[0021] The hazardous waste renewable material and carbon-containing material treatment system of this utility model embodiment has the following beneficial effects:

[0022] 1. The first furnace body pressurizes and feeds renewable materials such as hazardous waste, gasifying agents and reducing agents into the furnace, and they flow downwards to undergo physical and chemical reactions such as high-temperature pyrolysis gasification and ultra-high-temperature molten slag and metal reduction. While completely eliminating organic matter such as dioxins generated in the reaction and significantly reducing the pollution from trace heavy metal emissions in the ash slag generated in the reaction, it generates effective syngas and resource-utilizable raw materials such as glassy substances and elemental metal particles. It makes full use of the output sensible heat and kinetic energy of the first syngas and the rich hydrogen gas, providing rare fluidized kinetic energy, hydrogen source and heat source conditions, as well as reducing agent and raw material conditions for the pyrolysis gasification reaction in the second furnace body;

[0023] 2. Through thermal coupling integration technology, ultra-high temperature first syngas is directly transported to the second furnace body, making full use of the high-energy characteristics of the first syngas to achieve the purpose of pressurized rapid fluidized hydrogenation pyrolysis reaction conditions for carbon-containing materials in the second furnace body. This is to produce a second syngas rich in natural gas CH4 and light aromatic hydrocarbon HCl with high added value. By separating the second syngas and its carried solid material, namely hot semi-coke, and using the hot semi-coke as a reducing agent and raw material for the pyrolysis gasification reaction of the first furnace body, the energy consumption and operating cost of the entire production system are greatly reduced, the added value of the pyrolysis gasification slag products is increased, and the investment, operation and resource utilization efficiency are effectively improved. This achieves the resource utilization of renewable materials and the clean, harmless, economical and efficient utilization of other carbon-containing materials.

[0024] 3. By connecting the exhaust port of the first furnace body with the gas collection chamber and the slag pool, the first syngas generated in the first reaction chamber is discharged through the gas collection chamber and exhaust port after passing through the high-temperature slag bath, and the first syngas is subjected to ultra-high temperature treatment again to ensure the ultra-high temperature of the first syngas.

[0025] 4. By setting up slag dischargers, quenching slag collection tanks, and slag locks, the molten slag is quenched, collected, and discharged, realizing the resource utilization of renewable materials such as hazardous waste, while not generating fly ash and slag carrying primary and secondary hazardous wastes such as dioxins and trace heavy metals, so as to achieve the harmless utilization of renewable materials.

[0052] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following describes a system for treating hazardous waste renewable materials and carbon-containing materials according to an embodiment of the present invention.

[0054] like Figure 1 , Figure 2 and Figure 4 As shown, the hazardous waste renewable material and carbon-containing material treatment system of this utility model embodiment includes a first furnace body 1, a slag discharger 2, a second furnace body 3, a cyclone separator 4, and a metal sintering filter 5.

[0055] The first furnace body 1 includes a first reaction chamber 101 and a molten slag pool 102 arranged sequentially. The first furnace body 1 is provided with a first feed inlet 103, a first air inlet 104, and a first discharge outlet 105. The first feed inlet 103 is used to transport hazardous waste recyclable materials and first carbon-containing materials such as reducing agents. The first air inlet 104 is used to transport gasifying agents. Hazardous waste recyclable materials, first carbon-containing materials, and gasifying agents flow in parallel and downward in the first reaction chamber 101 and are pyrolyzed and gasified to generate molten slag and first syngas. A slag discharger 2 is provided at the first discharge outlet 105. The slag discharger 2 is used to collect, increase and maintain the ultra-high temperature and fluidity of the molten slag liquid, and control the intermittent discharge of the molten slag liquid. The output end of the slag discharger 2 is connected in sequence to a quench slag collection tank 6, a slag lock tank 7, and a first slag collection tank 102. A disc valve allows molten slag to be discharged through the first discharge port 105 and the slag discharger 2 into the quench slag collection tank 6. The ultra-high temperature molten slag that falls into the quench slag collection tank 6 is cooled and quenched into glassy slag and elemental metal particles by the circulating cooling water in the quench slag collection tank 6. The slag lock tank 7 and the first disc valve are used to collect and depressurize the glassy slag and elemental metal particles generated after cooling and quenching. The first furnace body 1 or the slag discharger 2 is provided with an exhaust port 8 for discharging the first syngas. The slag discharger 2 is provided with a first spray gun 201 for spraying a gasifying agent into the molten slag. By spraying a gasifying agent into the molten slag, the pyrolysis and gasification of the hazardous waste recyclable materials contained in the molten slag are further promoted, thereby increasing the temperature of the molten slag, the ambient temperature inside the first furnace body 1, and the temperature of the generated first syngas.

[0056] The second furnace body 3 includes a gas mixing chamber 301, a fluidized gas chamber 302, and a second reaction chamber 303 arranged sequentially. The second furnace body 3 is provided with a second air inlet 304 and a third air inlet 305 communicating with the gas mixing chamber 301, and a second feed inlet 306 and a second discharge outlet 307 communicating with the second reaction chamber 303. The second air inlet 304 is connected to the exhaust outlet 8 through a pipe. The third air inlet 305 is used to transport hydrogen. The front end of the second feed inlet 306 is connected in sequence to a material storage and transportation device 9, a crushing, drying and conveying device 10, and a pressurized feed tank 11. The material storage and transportation device 9, the crushing, drying and conveying device 10, and the pressurized feed tank 11 are used to transport the second carbon-containing material, such as the reducing agent. The second carbon-containing material, hydrogen and the first synthesis gas rise in parallel in the second reaction chamber 303 and mix rapidly to form a fluidized state for pyrolysis and gasification to generate the second synthesis gas and solid material.

[0057] Cyclone separator 4 and metal sintering filter 5 are connected in series at the second discharge port 307. Cyclone separator 4 and metal sintering filter 5 are used to separate the second syngas and the solid materials carried out by the second syngas, transport the separated syngas to the downstream gas treatment device, collect the separated solid materials and transport them to the first reaction chamber 101. A first processing unit 12 for processing the separated solid materials is provided between cyclone separator 4 and the first furnace body 1. A second processing unit 13 for processing the separated solid materials is provided between metal sintering filter 5 and the first furnace body 1. The first processing unit 12 includes a first ash collection tank 1201, a first pressure relief lock hopper 1202 and a first lock hopper disc valve 1203 provided at both ends of the first pressure relief lock hopper 1202. The second processing unit 13 includes a second ash collection tank, a second pressure relief lock hopper and a second lock hopper disc valve provided at both ends of the second pressure relief lock hopper.

[0058] The working principle of the resource-based harmless treatment system for hazardous waste recyclable materials and carbon-containing materials in this embodiment of the utility model is as follows: Hazardous waste recyclable materials and reducing agents, etc., enter the inner cavity of the first furnace body 1 through the first feed inlet 103, and the gasifying agent enters the inner cavity of the first furnace body 1 through the first air inlet 104. The hazardous waste recyclable materials, the first carbon-containing materials and the gasifying agent flow down in parallel in the first reaction chamber 101 to pyrolyze and gasify to generate slag and first synthesis gas. The slag accumulates in the slag pool 102. When the slag accumulates to the set liquid level, the slag discharger 2 is opened, and the molten slag liquid is discharged into the quenching slag collection tank 6 through the slag discharger 2. The slag is cooled and quenched into glassy slag and elemental metals in the quenching slag collection tank 6 by low-temperature circulating water. Then, it is intermittently discharged into the lock slag tank 7 and discharged into the atmospheric slag pool after pressure reduction.

[0059] The first syngas is discharged through the exhaust port 8 and enters the second furnace body 3 through the second air inlet 304, avoiding the first syngas from being cooled by the quench slag collection tank 6 in the first furnace body 1. It is directly mixed and heated with the medium and low temperature hydrogen in the gas mixing chamber 301 that enters through the third air inlet 305. The material storage and transportation device 9, the crushing, drying and conveying device 10 and the pressurized feeding tank 11 transport the reducing agent and other second carbon-containing substances to the second reaction chamber 303 through the second feed inlet 306. The mixed first syngas and hydrogen enter the second reaction chamber 303 through the fluidized gas chamber 302 and quickly form a fluidized state with the carbon-containing materials entering the furnace through the second feed inlet 306. They move upward in parallel to quickly heat, hydrogenate, pyrolyze and gasify to generate the second syngas and solid material, i.e., hot semi-coke.

[0060] The second syngas and the hot semi-coke it carries are discharged from the second furnace body 3 through the second discharge port 307 and enter the cyclone separator 4 for gas-solid separation. The separated syngas is sent to the downstream metal sintering filter 5. The solid material separated by the cyclone separator 4 is sent to the first reaction chamber 101 of the first furnace body 1 through the first processing unit 12. The syngas that has completed gas-solid separation in the metal sintering filter 5 is sent to the downstream syngas treatment and disposal device. The solid material separated by the metal sintering filter 5 is sent to the first reaction chamber 101 of the first furnace body 1 through the second processing unit 13. The solid material participates in the pyrolysis gasification slag reaction in the first reaction chamber 101 as a reducing agent and raw material, and provides heat for the pyrolysis gasification slag reaction in the first reaction chamber 101 with its sensible heat.

[0061] The hazardous waste renewable materials and carbon-containing materials treatment system of this utility model embodiment can effectively avoid the generation of secondary hazardous wastes such as fly ash and slag carrying organic matter such as dioxins and trace heavy metal pollutants, reduce system energy consumption and operating costs, significantly increase the added value of pyrolysis gasification slag products, improve system operation and resource utilization efficiency, and realize the resource utilization of renewable materials and the clean, harmless, economical and efficient utilization of other carbon-containing materials.

[0062] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the slag discharger 2 includes a pipe body 202, one end of which is connected to the first discharge port 105. The pipe body 202 is used to store molten slag. A first spray gun 201 is provided in the pipe body 202, and a second spray gun 203 is provided in the pipe body 202. The second spray gun 203 is used to spray lifting gas into the molten slag in the pipe body 202 to control the intermittent discharge of molten slag.

[0063] Specifically, the slag discharger 2 is equipped with a tube 202 with a central through-hole cavity inside, the upper part of which is also part of the molten slag pool 102; the outer edge of the central through-hole cavity of the slag discharger 2 is embedded and connected to a second spray gun 203 for supplying lifting gas, as well as a channel for supplying carbonaceous materials such as gasifying agents and reducing agents and cooling media, and a multi-channel spray gun and other components; the slag discharger 2 is used to receive the molten slag liquid flowing into the first reaction chamber 101 after the pyrolysis and gasification ash is melted at high temperature, to improve and maintain the liquid level, ultra-high temperature and fluidity of the molten slag liquid in the molten slag pool 102, and to control the intermittent discharge of the ultra-high temperature molten slag liquid; the operating space of the molten slag pool 102 is a space from the bottom of the first reaction chamber 101 The space within the pipe body 202 of the slag discharger 2, from the first slag discharge port to the position where the molten slag is lifted by the lifting gas; the pyrolysis and gasification ash is melted into slag liquid at high temperature and flows and accumulates in the molten slag pool 102 to form a liquid surface of ultra-high temperature slag liquid. This liquid surface bears the pressure of pyrolysis and gasification in the first reaction chamber 101. The design controls the formation of a pressure difference between the liquid surface and the lifting gas position at the bottom of the molten slag, which is lower at the top and higher at the bottom. The pressure difference can be controlled by controlling the amount of lifting pressure gas injected into the lower part of the slag discharger 2 by the second spray gun 203 on the slag discharger 2. That is, when the pressure of the lifting gas is lower than the sum of the gravity of the slag liquid above it and the pressure of the liquid surface, the liquid slag begins to be discharged. When the pressure difference is reduced to a certain set value, the discharge stops.

[0064] In some embodiments, such as Figure 1 The first furnace body 1 shown can also use a fluidized bed gasifier when the renewable materials such as hazardous waste that are fed into the furnace can be crushed into materials ≤5mm. However, unlike the solid slag discharge method of this type of fluidized bed gasifier, the lower opening of the conical first distribution plate 106 at the bottom of the first reaction chamber 101 of the fluidized bed gasifier used as the first furnace body 1 is connected to the above-mentioned high-temperature molten slag discharger 2.

[0065] like Figure 1As shown, the first furnace body 1 is a pyrolysis gasification furnace body formed by welding a vertical cylinder and its upper and lower ends with partially spherical, partially elliptical, or conical heads respectively. A first reaction chamber 101 is provided inside the first furnace body 1. An exhaust port 8 is installed at the center of the upper head of the first furnace body 1 to discharge the first synthesis gas generated by the pyrolysis gasification of the material entering the first reaction chamber 101. An inverted conical gasifying agent first distribution plate 106 is installed above the spherical bottom of the first furnace body 1. Above the first distribution plate 106 is the first reaction chamber 101 for the pyrolysis gasification of the material entering the furnace. At a height of 1000mm above the first distribution plate 106 in the first reaction chamber 101, multiple third spray guns 107 are arranged horizontally and equidistantly along the circumference of the furnace body, capable of feeding gasifying agents and reducing agents, etc., containing carbonaceous gaseous-solid-liquid materials, into the first reaction chamber 101 from outside the furnace. A first feed inlet 103 is located at the first... The upper opening of the distribution plate 106 is connected to the discharge end of the first processing unit 12, which conveys solid materials, through the first conveying pipe 14. The discharge end of the second processing unit 13 is provided with a second conveying pipe 15 that communicates with the first furnace body 1. The solid materials separated by the metal sintering filter 5 are conveyed to the first furnace body 1 through the second processing unit 13 and the second conveying pipe 15 to pressurize the reducing agent and other carbon-containing powders into the first reaction chamber 101 of the first furnace body 1. The side of the first distribution plate 106 near the first discharge port 105 is a chamber for pure oxygen and gasifying agents such as steam. The gasifying agent entering this chamber passes through the holes of the first distribution plate 106 and rises, establishing a fluidized bed with the furnace feed material above the first distribution plate 106, so as to efficiently carry out a series of physical and chemical reactions. The high-temperature first synthesis gas of 900 to 1000°C generated by the reaction is discharged from the exhaust port 8 at the top of the furnace body.

[0066] Optionally, the reducing agent and other carbon-containing powder separated by the metal sintering filter 5 and conveyed through the outlet of the second processing unit 13 can also be sent into the slag discharger 2 and the slag discharge port through the first spray gun 201; the cyclone separator 4 and the metal sintering filter 5 can also use their respective material legs and their feeding valves and feeding gas configurations to directly press the separated solid material, i.e., hot coke powder, into the first furnace body 1.

[0067] like Figure 1The first furnace body 1 shown is a fluidized bed gasifier. A high-temperature molten slag discharger 2 is installed at the bottom of the reaction chamber of the furnace body. The inner diameter of the tube 202 in the discharger 2 is 200 to 450 mm. The outer edge of the central cavity inside the tube 202 is embedded with and connected to a first spray gun 201 and a second spray gun 203, etc., for feeding in gasifying agent, lifting gas, reducing agent and other carbon-containing materials and cooling medium. The discharger 2 maintains the ultra-high temperature of the molten slag in the central cavity, i.e., the molten slag pool 102, and the flow of the molten slag through the oxidation and gasification reaction heat generated by the injection of gasifying agent and carbon-containing materials and lifting gas, and the lifting pressure at the bottom of the discharger 2. The system controls the intermittent discharge of molten slag and the lifting gas injected into the pipe body 202 by the second spray gun 203 is controlled to control the intermittent discharge of molten slag. The ultra-high temperature liquid slag discharged through the slag discharge port of the slag discharger 2 falls into the quenching slag collection tank 6 connected to its lower part, where it is quenched and crushed into small glassy slag and elemental metal particles of millimeter size by circulating quenching water in the tank. The glassy slag particles contain more than 85% glass. The quenching slag collection tank 6 removes the heat of the high temperature molten slag by circulating cooling water from its external cooling pipes. The quenched glassy slag and elemental metal particles are discharged after being reduced to normal pressure by the slag lock tank 7 and its pressure relief system.

[0068] like Figure 1 The second furnace body 3 shown is a pressurized rapid fluidized bed hydropyrolysis gasification furnace for carbon-containing powders such as reducing agents. The first synthesis gas (gas pressure 0.5 to 5.5 MPa) with an ultra-high temperature of 900 to 1000°C and rich in hydrogen, discharged from the exhaust port 8 of the first furnace body 1, enters the gas mixing chamber 301 of the second furnace body 3 through the first thermal coupling pipe 19. This heats and mixes with the second stream of low-temperature hydrogen from the downstream of the system entering the gas mixing chamber 301, causing it to rise into the fluidized gas chamber 302. Then, it passes through the second distribution plate 308 of the second furnace body 3 and enters the second reaction chamber 303 of the second furnace body 3. There, it flows parallel to the second carbon-containing materials, such as reducing agents, entering the second reaction chamber 303 from the second feed inlet 306 and above the second distribution plate 308, undergoing a rapid fluidized bed hydropyrolysis gasification reaction. After the reaction is complete... The gaseous and solid materials are discharged from the second furnace body 3 through the second discharge port 307 and then sent to the cyclone separator 4 and the sintering metal sintering filter 5 for gas-solid separation via the second thermal coupling pipe 20. The separated second synthesis gas is sent to the downstream unit for refining to generate gaseous products rich in hydrogen (H2), natural gas (CH4), light aromatics (HCl), and carbon monoxide (CO). The separated solid material, i.e., hot coke powder, enters the first reaction chamber 101 of the first furnace body 1 through the cyclone separator 4, the first processing unit 12, the first conveying pipe 14 and the first feed port 103. It then enters the first reaction chamber 101 of the first furnace body 1, the slag discharger 2 and the first discharge port 105 through the metal sintering filter 5, the second processing unit 13, the second conveying pipe 15 and the first spray gun 201, respectively.

[0069] In some embodiments, such as Figure 2 and Figure 3 As shown, the first feed inlet 103 includes a first sub-feed inlet 1031 and a second sub-feed inlet 1032. The first sub-feed inlet 1031 is located at the top of the first furnace body 1 and is used to transport hazardous waste recyclable materials. The second sub-feed inlet 1032 is located on the side wall of the first furnace body 1 and is used to transport first carbon-containing materials. The feeding assembly 16 includes a buffer bin 1601, a material lock hopper 1602, an upper plate valve 1603, a lower plate valve 1604, a conveying pipe 1605, and a receiving hopper 1606. The buffer bin 1601 is located at the first sub-feed inlet 1031. The material lock hopper 1602 is connected above the buffer bin 1601. The upper plate valve 1603 and the lower plate valve 1604 are spaced apart in the material lock hopper 1602. The conveying pipe 1605 is connected to the end of the material lock hopper 1602. The receiving hopper 1606 is connected to both ends of the conveying pipe 1605 and is used to collect materials. The receiving hopper 1606 is equipped with a power valve 1607, which is used to compress the material in the receiving hopper 1606 along a first direction. The conveying pipe 1605 is equipped with a pressure piston 1608 and a stop valve 1609 corresponding to the receiving hopper 1606. The pressure piston 1608 can move along a second direction perpendicular to the first direction, and the stop valve 1609 is adjustable along the first direction. The pressure piston 1608 and the stop valve 1609 are used to compress the material in the second direction to generate material blocks. The first furnace body 1 is equipped with a stirrer 18 cooled by externally supplied circulating cooling water. The material lock hopper 1602 and the buffer chamber 1601 are equipped with inlet and outlet pipes for pressure release, purging air, and feeding air, as well as control valve groups and filters.

[0070] Specifically, such as Figure 3As shown, the material lock hopper 1602 is connected at the end to the middle of the conveying pipe 1605. Two receiving hoppers 1606 are provided at both ends of the conveying pipe 1605, along with two sets of pressure pistons 1608 and stop valves 1609 corresponding to the receiving hoppers 1606. The two stop valves 1609 within the conveying pipe 1605 restrict the formation of a first buffer chamber 16010 and a second buffer chamber 16011 between themselves and the end of the material lock hopper 1602. Hazardous waste and other recyclable materials undergo simple front-end sorting; large materials are crushed or compressed into pieces with a single side less than 40 mm. Individual materials with a diameter of 0 mm or less than 550 mm are loaded into receiving hoppers 1606 above both ends of the conveying pipe 1605 by lifting hoppers. The individual materials fall into the receiving hoppers 1606 by their own weight. The power valve 1607 in the receiving hopper 1606 rotates to the side and downward, compacting the material once and closing the lower outlet of the receiving hopper 1606. Then, the pressing piston 1608 moves towards the stop valve 1609 in the conveying pipe 1605 to compact the material a second time, opening its passage to face the corresponding stop valve 1609. 9. The pressure piston 1608 continues to push the compacted material block, moving it to the first buffer chamber 16010 and the second buffer chamber 16011 within the conveying pipe 1605. This process is repeated to complete the pressing and temporary storage of other material blocks. After the pressure gas charging and depressurization assembly of the material lock hopper 1602 has been depressurized, the upper valve 1603 of the material lock hopper 1602 is opened, and then the stop valve 1609 at one end of the conveying pipe 1605 is opened. The pressure piston 1608 at that end pushes the material block temporarily stored in the conveying pipe 1605 to the first buffer chamber 16010 and the second buffer chamber 16011. Material blocks on the first buffer chamber 16010 and the second buffer chamber 16011 are pushed one after another to the top of the material lock hopper 1602. The material blocks fall into the material lock hopper 1602 by their own weight until all the material blocks temporarily stored in the conveying pipe 1605 are pushed into the material lock hopper 1602. It should be noted that during the operation, the waste material is compressed into a cylinder with a height greater than 0.6 meters and a certain rigidity to prevent it from tilting and falling easily when pushed above the material lock hopper 1602 due to the weight.

[0071] After closing the upper valve 1603, the pressurization of the material lock hopper 1602 pressure charging and depressurization assembly is initiated and completed, and the pressure is then balanced with that in the furnace cavity. The lower valve 1604 is then opened, and the material in the material lock hopper 1602 falls into the material buffer chamber 1601 in parallel with its own weight and the pressure of the purging air. The buffer chamber 1601 is approximately 4 meters high, with the upper cavity section having a height of 0.5 to 2 meters and the material section having a height of 2 to 3.5 meters. Its lower outlet is connected to the first sub-feed inlet 1031 of the first furnace body 1. As the material inside the furnace undergoes pyrolysis, gasification, and melting, and its slag and the first syngas are discharged, this section of material, along with the blowing gas, gasifying agent, reducing agent, etc., sent into the first reaction chamber 101 from the top and lower part of the furnace body, flows down to participate in the reaction and completes one feeding process. Then, the next feeding process is completed by the receiving hopper 1606 at the other end of the conveying pipe 1605. This process is repeated to achieve continuous feeding of gasified material, so that the weight ratio of renewable material to reducing agent entering the furnace is 1:0.5 to 5.

[0072] Material blocks falling into the first reaction chamber 101 of the first furnace body 1 through the first sub-feed inlet 1031 are broken up by a water-cooled agitator 18 installed at the top of the first reaction chamber 101 to accelerate the reaction rate of pyrolysis and gasification of renewable materials entering the first reaction chamber 101.

[0073] In some embodiments, the first furnace body 1 or the slag remover 2 is provided with a gas collecting chamber 17 corresponding to the exhaust port 8. The gas collecting chamber 17 is connected to the molten slag pool 102. The first syngas is discharged from the gas collecting chamber 17 and the exhaust port 8 after passing through the molten slag liquid bath. The first syngas is subjected to a liquid bath by the high-temperature molten slag, which increases the temperature of the first syngas when it is output from the exhaust port 8, thus ensuring the heat provided to the second furnace body 3.

[0074] In some embodiments, such as Figure 2 As shown, the first furnace body 1 is provided with a first cone 108 and a second cone 109. The cross-sectional diameters of the first cone 108 and the second cone 109 decrease along the direction close to the first discharge port 105. The first cone 108 is located on the side of the second cone 109 close to the first discharge port 105. A discharge pipe is connected between the end of the first cone 108 and the first discharge port 105. The discharge pipe and the side of the first cone 108 away from the first discharge port 105 restrict the slag pool 102. The exhaust port 8 is located between the first cone 108 and the second cone 109. Part of the second cone 109 is immersed in the molten slag in the molten slag pool 102. The first cone 108, the second cone 109 and the inner wall of the first furnace body 1 restrict the gas collecting chamber 17 on the surface of the molten slag in the molten slag pool 102.

[0075] Specifically, such as Figure 2As shown, a first cone 108 and a second cone 109 are sequentially arranged inside the first reaction chamber 101 near the first discharge port 105. The first cone 108 is located on the side of the second cone 109 near the first discharge port 105. A discharge pipe is provided at the end of the first cone 108 corresponding to the first discharge port 105. The discharge pipe and the side of the first cone 108 away from the first discharge port 105 restrict the slag pool 102. The molten slag in the slag pool 102 submerges part of the second cone 109. The first cone 108, the second cone 109, and the inner wall of the first furnace body 1 are within the slag pool 102. The gas collecting chamber 17 is restricted from the surface of the molten slag. The exhaust port 8 is connected to the first reaction chamber 101 through the gas collecting chamber 17 and the molten slag pool 102. During normal operation, the connection between the exhaust port 8 and the first reaction chamber 101 is blocked by the molten slag. The liquid level of the molten slag pool 102 is about 200mm higher than the lower end of the first cone 108. By setting and controlling the pressure difference between the first reaction chamber 101 and the exhaust port 8 as well as the liquid level of the molten slag, the first synthesis gas generated by the pyrolysis and gasification of the first reaction chamber 101 can only pass through the molten slag in the molten slag pool 102 into the gas collecting chamber 17 and then be discharged from the furnace body through the exhaust port 8.

[0076] like Figure 2 As shown, the material blocks entering the furnace from the first sub-feed inlet 1031 are crushed by the circulating water-cooled agitator 18. Simultaneously, the reducing agent and other carbonaceous materials (hot coke powder at approximately 750 to 850°C) entering the top of the furnace cavity through the second sub-feed inlet 1032 are heated and mixed on the cross-section of the first reaction chamber 101, undergoing dehydration, pyrolysis, and gasification. Under its own weight and the pressure of the upper pressurized purging gas and reducing agent feed gas, it flows downwards and interacts intensely with the oxygen, steam, and other gasifying agents injected into the furnace through the first air inlet 104, as well as the reducing agent and other carbonaceous materials injected into the furnace cavity through the third spray gun 107 on the first furnace body 1, or the high-calorific-value waste liquid or solid waste injected into the furnace cavity by the third spray gun 107. Within the first reaction chamber 101, towards the direction of the molten slag pool 102, it is sequentially divided into chambers A, B, and C. By controlling the amount of carbonaceous materials such as gasifying agents and reducing agents fed into the furnace, and under the medium-temperature (800 to 600°C), high-temperature (800 to 1350°C), and ultra-high-temperature (1400 to 1600°C) conditions of chambers A, B, and C of the first furnace body 1 and the slag discharge port of the slag discharger 2, the heat generated by the consumption of materials is fully utilized to continuously complete a series of physical and chemical reactions such as drying pyrolysis, gasification, and ash melting of renewable materials. The first syngas generated by the gas-solid (liquid) parallel flow decomposition gasification reaction in the first reaction chamber 101 is crude syngas. After passing through the ultra-high-temperature molten slag bath, the first syngas enters the gas collecting chamber 17 and is then discharged from the furnace body through the exhaust port 8 to provide the downstream ultra-high-temperature first syngas at 1200 to 1500°C, instead of the 250 to 500°C (excluding the 900°C of the Shell furnace) that other optional gasification furnace technologies can currently only provide.

[0077] like Figure 2 In the first furnace body 1 shown, the slag from the pyrolysis and gasification of renewable materials such as hazardous waste and carbonaceous materials such as reducing agents in the first reaction chamber 101 is melted into ultra-high temperature molten slag in the upper part of the chamber C, i.e. the molten slag pool 102 and in the molten slag pool 102. The slag discharger 2 mentioned above is installed at the lower opening of the molten slag pool 102. The slag discharger 2, the quenching slag collection tank 6 and the slag locking tank 7 are used to control the liquid level of the molten slag, discharge it, quench it with water, and depressurize and discharge the glassy body and small particles of elemental metal generated by quenching.

[0078] like Figure 2 As shown, the second furnace body 3 is a pressurized rapid fluidized bed hydrolysis gasification furnace for carbon-containing powders such as reducing agents. The ultra-high temperature first synthesis gas (1200-1500℃, gas pressure 0.5-5.5MPa) discharged from the exhaust port 8 of the first furnace body 1 enters the gas mixing chamber 301 at the bottom of the second furnace body 3 through the first thermal coupling pipe 19. Here, it mixes with hydrogen gas (temperature <50℃, gas pressure 1-6.0MPa) from the downstream purification device and is cooled to 1100℃. It then rises into the fluidized gas chamber 302 and passes through the second distribution plate 308 inside the second furnace body 3, entering the second reaction chamber 303 of the second furnace body 3. There, it mixes with hydrogen gas (temperature <50℃, gas pressure 1-6.0MPa) fed into the second distribution plate 308 from outside the furnace. The reducing agent and other carbon-containing materials on the surface undergo a rapid fluidized hydropyrolysis gasification reaction. The second syngas generated by the reaction and the solid materials (hot coke powder) it carries are transported to the cyclone separator 4 and the sintered metal sintering filter 5 through the second thermal coupling pipe 20. After being separated by the cyclone separator 4 and the sintered metal sintering filter 5, the second syngas is sent to the downstream gas treatment device. The solid materials separated by the cyclone separator 4 enter the first reaction chamber 101 through the first processing unit 12, the first conveying pipe 14 and the second sub-inlet 1032. The solid materials separated by the sintered metal sintering filter 5 enter the first reaction chamber 101, the slag discharger 2 and the slag discharge port through the second processing unit 13 and the second conveying pipe 15.

[0079] The top of the first reaction chamber 101 of the first furnace body 1 is maintained at a positive pressure of 0.6 to 6.0 MPa, and the pressure of the second synthesis gas discharged from the metal sintering filter 5 is between 0.1 and 5.5 MPa. The reaction flow fields of the slag pyrolysis gasification of the first furnace body 1 and the rapid fluidized hydrogenation pyrolysis gasification of the second furnace body 3 are both gas-solid-liquid parallel flow downward or upward reaction. The first reaction chamber 101, slag pool 102 and slag discharger 2 of the first furnace body 1 are fed with sufficient oxygen and reducing agent. While providing sufficient heat of pyrolysis gasification reaction and ultra-high temperature heat of ash melting 2, the carbon as reducing agent can also ensure that the metal oxides in the solid waste are reduced to elemental metals as much as possible in the melting section, so as to significantly reduce the content of trace metal oxides in the glass.

[0080] In some embodiments, such as Figure 4 As shown, an inclined extension pipe section 204 is connected to the pipe body 202. The end opening of the extension pipe section 204 away from the pipe body 202 forms an exhaust port 8. The exhaust port 8 is located on the side near the first discharge port 105 at the connection between the extension pipe section 204 and the pipe body 202. Molten slag flows inside the extension pipe section 204. The molten slag liquid level inside the extension pipe section 204 and the exhaust port 8 restrict the exit of the gas collection chamber 17.

[0081] By setting an extension pipe section 204 on the pipe body 202 of the slag discharger 2, a gas collecting chamber 17 is formed above the molten slag surface in the extension pipe section 204, so that the first synthesizer in the first reaction chamber 101 passes through the molten slag and the gas collecting chamber 17 and is discharged from the exhaust port 8, which helps to ensure the gas temperature of the first synthesis gas.

[0082] In some embodiments, such as Figure 4 As shown, it includes a high-pressure feeding device 21, which is a high-pressure coal slurry pump or a high-pressure gas feed tank. The high-pressure feeding device 21 is located downstream of the first processing unit 12 and the second processing unit 13. The output end of the high-pressure feeding device 21 is connected to the first feed port 103 of the first furnace body 1 to convey solid materials to the first reaction chamber 101. These solid materials are mixed with the powder of hazardous waste and other renewable materials sent here, and after being pressurized by the high-pressure feeding device 21, they are sent into the first reaction chamber 101 in the first furnace body 1 for slag gasification reaction.

[0083] Specifically, such as Figure 4 As shown, when the recyclable materials such as hazardous waste fed into the furnace are crushable and grindable solid materials ≤0.075mm, the first furnace body 1 can also use a gasifier with widely used fluidized bed coal-water slurry or dry coal powder feed. This type of fluidized bed gasifier has a varying number of third spray guns 107 at the top or circumferential side of its furnace body; however, unlike the current low-temperature exhaust method of 200 to 500℃ (including the Shell gasifier at 900℃) used in similar fluidized bed gasifiers, the first discharge port 105... The high-temperature slag discharger 2 is connected and installed. The liquid surface of the ultra-high temperature slag pool 102 is 50mm above the bottom opening of the inverted conical sealed bottom of the first reaction chamber 101 of the first furnace body 1. The space between the slag liquid surface, the first discharge port 105 and the contact surface between the slag and the lifting gas in the tube body 202 of the discharger 2 is formed. The tube body 202 of the discharger 2 is provided with an extension pipe section 204 for discharging the first synthesis gas. The discharger 2 integrates slag discharge and exhaust.

[0084] like Figure 4The first furnace body 1 shown is a gasifier of the fluidized bed type. The bottom of the gasifier reaction chamber is equipped with a high-temperature slag discharger 2 that integrates slag discharge and exhaust. The first syngas and high-temperature slag are discharged through the slag discharger 2. The first syngas enters the ultra-high temperature slag pool 102102 from the first discharge port 105 at the bottom of the first reaction chamber 101. After being washed by the ultra-high temperature molten slag liquid, the high-temperature ash slag it carries is deeply melted into ultra-high temperature molten slag liquid. The first syngas passes through the ultra-high temperature molten slag liquid and enters the gas collection chamber 17. It is directly discharged to the outside through the exhaust port 8 to provide ultra-high temperature first syngas at 1200 to 1500°C, instead of the 250-500°C of other optional gasifier technologies (nor the 900°C of Shell furnaces). The pressure kinetic energy, sensible heat, and hydrogen-rich syngas of this ultra-high temperature first syngas provide rare reaction kinetic energy, reaction heat, and important reaction raw material hydrogen for the application of the new generation carbon conversion reaction technology, namely the second furnace body 3.

[0085] like Figure 4 As shown, the second furnace body 3 is a pressurized rapid fluidized hydropyrolysis gasification furnace for carbon-containing powders such as reducing agents. The ultra-high temperature first synthesis gas (1200-1500℃, gas pressure 0.5-5.5MPa) discharged from the exhaust port 8 of the first furnace body 1 enters the gas mixing chamber 301 of the second furnace body 3 through the first thermal coupling pipe 19. This gas heats and mixes with the second stream of low-temperature hydrogen from the downstream of the system entering the gas mixing chamber 301, causing it to rise into the fluidized gas chamber 302 and pass through the second distribution plate 308 within the second furnace body 3. It then enters the second reaction chamber 303 of the second furnace body 3, where it flows parallel to the carbon-containing materials such as reducing agents fed into the second distribution plate 308 from outside the furnace via the second feed port 306, undergoing rapid fluidized hydropyrolysis. The gasification reaction produces a second syngas and its carried solid material (hot coke powder). These are then sent to a cyclone separator 4 and a sintered metal sintering filter 5 via a second thermal coupling pipe 20 for gas-solid separation. The separated second syngas is sent to downstream units for refining to produce high-value-added gaseous products such as hydrogen, natural gas, light aromatics, and carbon monoxide. The solid material separated by the cyclone separator 4 and the sintered metal sintering filter 5 is fed into a high-pressure feeding device 21 via a first processing unit 12 and a second processing unit 13. Carbon-containing powders such as reducing agents enter the first reaction chamber 101 of the first furnace body 1 via the high-pressure feeding device 21 and the first feed inlet 103 to undergo a series of gasification reactions to produce a first syngas rich in carbon monoxide and hydrogen.
