Description

Technical Field

[0001] The invention belongs to the technical field of solid and hazardous waste treatment, and particularly relates to a multi-solid and hazardous waste energy resource collaborative cascade utilization system in the green energy valley mode of a waste-free city. Background Art

[0002] At present, the disposal and utilization of solid waste have undergone two generations of technological innovations. Among them, the first-generation technology is the method of incineration + landfill. This method faces problems such as large investment, high operating costs, and the rapid decline in the disposal price of hazardous waste with no profit. The second-generation technology is the co-disposal and utilization of solid and hazardous waste in cement kilns. Although it is the best technology for disposing of hazardous waste, with the development of technology, it has also gone through external hot disk furnaces, step furnaces, and even some have considered external pre-combustion facilities such as gasifiers. A large number of innovative technologies have also solved some problems in the actual operation of the project. However, a large number of harmful elements are brought into the cement kiln in this disposal method, which will affect the quality fluctuation of clinker and still have certain limitations in terms of disposal scale and energy utilization efficiency.

[0003] At the same time, according to the "Review Guidelines for Operating Permits for Co-disposal of Hazardous Wastes in Cement Kilns (Trial)", its pretreatment refers to the process of pre-treating hazardous waste such as drying, crushing, screening, neutralizing, stirring, mixing, compatibility, and pre-burning in order to meet the requirements of entering the kiln (mill) for co-disposal in cement kilns. Among them, pre-burning is the most efficient, safest, and most thorough means to solve the pre-treatment of co-disposal of hazardous waste in cement kilns. However, at present, there are two common problems in the industry in China regarding pre-burning as a pre-treatment process: one is the lack of core pre-burning equipment; the other is that there is no way out for the cascade use of high-temperature energy generated after pre-burning, resulting in energy waste, and there is still room for improving the efficiency of alternative fuel raw materials. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multi-solid and hazardous waste energy resource collaborative cascade utilization system in the green energy valley mode of a waste-free city in view of the deficiencies of the existing technology. The present invention realizes the energy conversion of comprehensive utilization of multi-solid and hazardous waste and the cascade utilization of waste heat energy, and a series of core equipment for the cascade use of renewable and utilizable solid and hazardous waste products such as waste activated carbon, waste SCR catalysts, and waste metal packaging. Without the supply of fossil energy, it can operate in a self-circulating manner, thus forming a complete closed-loop ecological system and maximizing the utilization value of solid and hazardous waste.

[0005] This solution is achieved through the following technical measures: A multi-solid and hazardous waste energy resource collaborative cascade utilization system in the green energy valley mode of a waste-free city includes a solid and hazardous waste pre-burning pretreatment energy generation and conversion system, a cyclone dust collection system, an energy cascade utilization and product coupling modification system, and an exhaust gas centralized collection and disposal system connected in series in sequence;

[0006] Solid and hazardous waste pre-burning pretreatment energy generation and conversion system, which pre-burns and pre-treats high calorific value solid and hazardous waste materials to generate high-temperature flue gas as energy;

[0007] Cyclone dust collection system, which dusts and purifies the high-temperature flue gas generated by the solid and hazardous waste pre-burning pretreatment energy generation and conversion system, and converts all the high-temperature flue gas into directly usable high-temperature flue gas. The high-temperature flue gas can be supplied to the energy cascade utilization and product coupling modification system, and can also be directly connected to supply the cement kiln decomposition furnace, coal-fired power generation boiler, metallurgical furnace, domestic waste incineration special furnace, hazardous waste incineration special furnace, and chemical industry special furnace;

[0008] Energy cascade utilization and product coupling modification system, including one or more groups of parallel subsystems. Each group of subsystems includes a fixed jacket desorption device or a rotary jacket desorption device, a secondary denitration device, a steam generation device, and an induced draft device connected in series in sequence. The front end of the fixed jacket desorption device or the rotary jacket desorption device is connected in series with the outlet of the high-temperature flue gas. The high-temperature flue gas output by the fixed jacket desorption device or the rotary jacket desorption device enters the secondary denitration device for secondary denitration treatment. The denitrified flue gas enters the steam generation device and cools down in the steam generation device to generate saturated steam or superheated steam. The saturated steam or the superheated steam is output by the induced draft device and can be used as secondary energy for the water washing fly ash evaporation crystallization process, activated carbon pore restoration, SCR catalyst revival, precious metal extraction heating, and steam curing type building material product production. The flue gas after production is discharged into the waste gas centralized collection and disposal system. The remaining saturated steam or superheated steam can generate electric energy through a waste heat power generation device;

[0009] Waste gas centralized collection and disposal system, which centrally treats the flue gas to make the flue gas meet the discharge standards.

[0010] Preferably, the solid and hazardous waste pre-burning pretreatment energy generation and conversion system includes an offline pretreatment gasifier and a grate furnace connected thereto. The solid and hazardous waste materials are dried and partially pre-burned in the grate furnace and then enter the offline pretreatment gasifier. High-temperature flue gas is generated during the gasification process of the solid and hazardous waste in the offline pretreatment gasifier.

[0011] Preferably, a feeding port for ammonia-containing medium materials is connected to the cyclone dust collection system, and the high-temperature flue gas realizes primary denitration in the cyclone dust collection system through the active ammonia flue gas denitration method;

[0012] The secondary denitration device is SNCR or SCR denitration.

[0013] Preferably, the rotary jacket desorption device includes a high-temperature superconducting steel jacket disposed obliquely and at least one outer thermal insulation jacket. The outer thermal insulation jacket is concentrically sleeved outside the high-temperature superconducting steel jacket. An external heating zone is formed between the outer wall of the high-temperature superconducting steel jacket and the inner wall of the outer thermal insulation jacket. The inside of the high-temperature superconducting steel jacket is a solid waste material channel, and the inside of the external heating zone is a high-temperature flue gas channel. Along the conveying direction of the solid waste material, the high-temperature superconducting steel jacket and the outer thermal insulation jacket are inclined downward from top to bottom. The particulate matter mixed in the high-temperature flue gas falls to the bottom of the external heating zone by its own gravity during the flow.

[0014] Preferably, the fixed jacket desorption device includes a kiln body disposed horizontally and a high-temperature superconducting steel jacket arranged in parallel throughout the kiln body. A high-temperature flue gas channel is formed between the outer wall of the high-temperature superconducting steel jacket and the inner wall of the kiln body. The inner cavity of the kiln body is divided into five working section intervals along its length: a heating-up section, a low-temperature heat preservation section, a high-temperature heating-up section, a high-temperature heat preservation section, and a cooling-down section.

[0015] Preferably, when the fixed jacket desorption device is adopted in the subsystem, the multi-source solid and hazardous waste energy resource utilization system of the waste-free urban green energy valley mode can be used for the roasting and regeneration process of waste SCR catalysts, the roasting and recovery process of waste metal packaging contaminants, and the sintering of solid waste-based building material components;

[0016] When the fixed jacket desorption device is used for the roasting and regeneration process of waste SCR catalysts, after the waste SCR catalysts go through processes such as soot blowing, ultrasonic cleaning, pickling, and reagent activation, they enter the fixed jacket desorption device and sequentially pass through the five working section intervals of the heating-up section, low-temperature heat preservation section, high-temperature heating-up section, high-temperature heat preservation section, and cooling-down section of the fixed jacket desorption device for the roasting process, generating high-temperature flue gas. The high-temperature flue gas is used to control the temperature of the thermal environment inside the fixed jacket desorption device between 600 - 700 °C. Finally, it leaves from the outlet of the fixed jacket desorption device. The entire roasting process takes 7 hours. The moisture in the solution during the roasting process is removed in the form of water vapor in the heating-up section. After drying, the waste SCR catalysts are immersed in ammonium metavanadate reagent and ammonium metatungstate reagent. Both ammonium metavanadate reagent and ammonium metatungstate reagent react with oxygen to form the active components V2O5 and WO3 of the catalyst and remain on the surface and in the micropores of the catalyst. Then, they enter the fixed jacket desorption device again, and the active components V2O5 and WO3 are fixed in the SCR catalyst through the high-temperature flue gas. A small amount of ammonia is generated during the conversion process of ammonium metavanadate and ammonium metatungstate. The ammonia is introduced into an offline pretreatment gasification furnace for secondary combustion treatment under negative pressure. The flue gas after the catalyst roasting is subjected to secondary denitrification treatment by a secondary denitrification device and then enters the subsequent steam generation device, where it is directly cooled to 200 °C to generate saturated steam;

[0017] The conversion reactions during the above process are as follows:

[0018] 4NH4VO3 + 5O2 → 4V2O5 + 2H2O↑ + 4NH3↑

[0019] (NH4)6H2W 12 O 40 → 12WO3 + 4H2O↑ + 6NH3↑;

[0020] When the fixed jacket desorption device is used for the roasting recovery processing of waste metal packaging contaminants, the thermal environment temperature inside the fixed jacket desorption device is controlled between 800 - 900 °C by high-temperature flue gas, and it stays for 120 minutes. The waste gas generated in the furnace is introduced into an offline pretreatment gasification furnace for secondary combustion treatment under negative pressure; after the flue gas after heat exchange of the roasted waste metal packaging contaminants undergoes secondary denitrification in the secondary denitrification device, it enters the steam generation device at the back end, and directly cools down to 200 °C in the steam generation device to generate saturated steam or superheated steam;

[0021] When the fixed jacket desorption device is used for the sintering of solid waste-based building material components, the temperature in the preheating section of the kiln body of the fixed jacket desorption device is 400 - 500 °C, the temperature in the sintering section is 1100 - 1120 °C, and the temperature in the cooling section is 300 - 400 °C. The flue gas discharged from the fixed jacket desorption device undergoes secondary denitrification in the secondary denitrification device, and then enters the steam generation device at the back end, and directly cools down to 200 °C in the steam generation device to generate saturated steam or superheated steam.

[0022] Preferably, when a rotary jacket desorption device is adopted in the subsystem, the waste-free urban green energy valley mode multi-source solid and hazardous waste energy resource utilization system can be used for the thermal desorption and dioxin removal process of municipal solid waste incineration fly ash, the activation and regeneration process of waste activated carbon, and the anaerobic pyrolysis roasting process of lithium battery recycling;

[0023] When the rotary jacket desorption device is used for the thermal desorption and dioxin removal process of municipal solid waste incineration fly ash, the directions of the fly ash material in the high-temperature superconducting steel jacket and the high-temperature flue gas in the external heating area are opposite to each other, and it stays for 20 - 40 minutes to complete the detoxification treatment. The waste gas generated by the thermal desorption of fly ash in the high-temperature superconducting steel jacket is introduced into an offline pretreatment gasification furnace for secondary combustion treatment under negative pressure; the high-temperature flue gas after heat exchange with the fly ash material enters the secondary denitrification device for secondary denitrification treatment, and the denitrified flue gas enters the steam generation device at the back end, and directly cools down to 200 °C in the steam generation device to generate saturated steam or superheated steam;

[0024] When the rotary jacket desorption device is used in the processing of the waste activated carbon activation and regeneration process, the thermal environment temperature in the rotary jacket desorption device is controlled between 600 - 900 °C by using high-temperature flue gas. At this temperature, the organic matter adsorbed in the waste activated carbon decomposes and ashes. At the same time, saturated steam is introduced into the rotary jacket desorption device for pore reactivation of the waste activated carbon; the flow directions of the waste activated carbon material in the temperature superconducting steel jacket and the high-temperature flue gas in the external heating zone are reverse to each other, and the residence time is 50 - 60 minutes. The waste gas generated during the activation and regeneration of the waste activated carbon in the temperature superconducting steel jacket is introduced into an offline pre-treatment gasification furnace for secondary combustion treatment under negative pressure. The high-temperature flue gas after heat exchange with the waste activated carbon enters the secondary denitrification device for secondary denitrification treatment, and the denitrified flue gas enters the steam generation device at the rear end, where it is directly cooled to 200 °C to generate saturated or superheated steam;

[0025] When the rotary jacket desorption device is used in the processing of the anaerobic pyrolysis roasting process for lithium battery recycling, the thermal environment of the rotary jacket desorption device is controlled in an anaerobic state above 450 °C by using high-temperature flue gas. The discharged, disassembled, and roughly crushed waste lithium batteries are transported into the rotary jacket desorption device and pyrolyzed for 30 - 60 minutes to complete the volatilization of the electrolyte and the dissolution of the battery film. The waste gas generated during the pyrolysis roasting of the waste lithium batteries in the temperature superconducting steel jacket is introduced into an intermittent defluorination device under negative pressure. After removing hydrogen fluoride from the pyrolysis waste gas, it enters the offline pre-treatment gasification furnace for secondary combustion treatment; the flue gas after heat exchange during the pyrolysis roasting of the waste lithium batteries undergoes secondary denitrification in the secondary denitrification device and then enters the steam generation device at the rear end, where it is directly cooled to 200 °C to generate saturated steam or superheated steam.

[0026] Preferably, the treatment method for the centralized treatment of flue gas by the waste gas centralized collection and disposal system includes one or more of the processes of acid removal, activated carbon injection, GORE denitrification catalytic bag dust collection and denitrification, and electrostatic dust removal.

SPECIFIC IMPLEMENTATION MANNER

[0034] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific implementation manners and in combination with its drawings.

[0035] A multi-source solid hazardous waste energy resource collaborative hierarchical utilization system for the waste-free city green energy valley model includes a solid hazardous waste pre-burning pretreatment energy generation and conversion system, a cyclone dust collection system, an energy hierarchical utilization and product coupling modification system, and an exhaust gas centralized collection and disposal system connected in series in sequence.

[0036] Among them, the solid hazardous waste pre-burning pretreatment energy generation and conversion system pre-burns and pre-treats high-calorific solid hazardous waste materials to generate high-temperature flue gas as energy. The solid hazardous waste pre-burning pretreatment energy generation and conversion system includes an off-line pretreatment gasification furnace and a grate furnace connected thereto. The solid hazardous waste materials enter the off-line pretreatment gasification furnace after being dried and partially pre-burned in the grate furnace, and high-temperature flue gas is generated during the gasification process of the solid hazardous waste materials in the off-line pretreatment gasification furnace.

[0037] Cyclone dust collection system, which conducts dust collection and purification treatment on the high-temperature flue gas generated by the solid hazardous waste pre-burning pretreatment energy generation and conversion system, and converts all the high-temperature flue gas into directly usable high-temperature flue gas. The temperature of the high-temperature flue gas is 800°C - 1150°C. The high-temperature flue gas can be supplied to the energy cascade utilization and product coupling modification system, and can also be directly connected to supply other energy-consuming scenarios such as cement kiln decomposition furnaces, coal-fired power boilers, metallurgical furnaces, special domestic waste incineration furnaces, special hazardous waste incineration furnaces, and special chemical furnaces. An inlet for ammonia-containing medium materials is connected to the cyclone dust collection system. The high-temperature flue gas realizes primary denitrification through the active ammonia flue gas denitrification method in the cyclone dust collection system; ammonia-containing medium materials (such as aluminum ash, ammonia water, urea, etc.) are added to the cyclone dust collection system through the inlet for primary denitrification, realizing complementary functions with the secondary denitrification device at the rear end. The denitrification method of this ammonia-containing medium material mainly includes SNCR denitrification process and SCR denitrification process. Among them, the SNCR denitrification process is to spray a reducing agent containing NHx groups (such as ammonia gas, ammonia water or urea, etc.) into the area where the furnace temperature is 850°C - 1150°C. The reducing agent is sprayed through a spray gun installed in the platen superheater area, quickly thermally decomposed into NH3 and other by-products, and then NH3 undergoes SNCR reaction with NOx in the flue gas to generate N2 and H2O. The SCR denitrification process uses ammonia gas as a reducing agent. After being diluted to a safe concentration (volume concentration < 5%) by air in the ammonia dilution system, it is injected into the raw flue gas in the ammonia injection grid flue through the ammonia injection system. The mixed gas in the SCR reactor, under the action of a catalyst, undergoes an oxidation-reduction reaction with the injected reducing agent to generate N2 and H2O that do not pollute the environment, achieving the purpose of removing pollutants in the raw flue gas.

[0038] Solid hazardous waste materials enter the solid hazardous waste pre-burning pretreatment energy generation and conversion system for pre-burning pretreatment. The pre-burning environment in this solid hazardous waste pre-burning pretreatment energy generation and conversion system combines various forms such as calcination, pyrolysis, and gasification. After passing through the cyclone dust collection system for dust collection and purification treatment, it is all converted into directly usable high-temperature flue gas. The temperature of the high-temperature flue gas is 800 - 1150°C. At the same time, the cyclone dust collection system can also act as a secondary combustion chamber. The main functions of the secondary combustion chamber include the following aspects:

[0039] 1. Prevent secondary pollution: The secondary combustion chamber incinerates the flue gas generated by the high-temperature incineration offline type pretreatment gasification furnace at high temperature to ensure that the toxic and harmful substances in the flue gas are completely decomposed, thereby preventing secondary pollution and protecting the environment;

[0040] 2. Improve combustion efficiency: The high-temperature environment (usually close to 1000 degrees Celsius) in the secondary combustion chamber helps to completely burn the garbage, reduce the generation of unburned products such as carbon black and pulverized coal, and improve the incineration efficiency;

[0041] 3. Ensure safe operation: The secondary combustion chamber is provided with refractory materials, thermal insulation materials and adiabatic materials to reduce heat loss and improve incineration efficiency;

[0042] 3. An explosion-proof device and an emergency discharge chimney are provided at the top of the secondary combustion chamber to ensure that pressure can be safely released in case of emergency and guarantee the safe operation of the system;

[0043] 4. Strong adaptability: The secondary combustion chamber has strong adaptability to changes in incinerated materials and can handle special garbage with high water content to ensure normal combustion;

[0044] 5. Efficient heat transfer: The secondary combustion chamber can ensure sufficient contact between flue gas and particulate matter, extend the residence time of flue gas, improve reaction efficiency, and at the same time make the dust in the flue gas settle by gravity to achieve the effective discharge of ash residue.

[0045] The energy cascade utilization and product coupling modification system includes one or more groups of parallel subsystems, and the number of parallel subsystems can be selected according to actual production capacity requirements. The higher the actual production capacity, the more parallel subsystems are required. Each group of subsystems includes a fixed jacket desorption device or a rotary jacket desorption device, a secondary denitration device, a steam generation device and an induced draft device connected in series in sequence. The secondary denitration device is SNCR or SCR denitration. The front end of the fixed jacket desorption device or the rotary jacket desorption device is connected in series with the outlet of the high-temperature flue gas. The high-temperature flue gas output by the fixed jacket desorption device or the rotary jacket desorption device enters the secondary denitration device for secondary denitration treatment. The denitrified flue gas enters the steam generation device and cools down in the steam generation device to generate saturated steam or superheated steam. The saturated steam or the superheated steam is output through the induced draft device and can be used as secondary energy for the processes of washing fly ash evaporation crystallization, activated carbon pore restoration, SCR catalyst revival, precious metal extraction heating and steam curing building materials production. The flue gas after production is discharged into the waste gas centralized collection and disposal system, and the remaining saturated steam or superheated steam can generate electric energy through a waste heat power generation device.

[0046] The rotary jacket desorption device includes a high-temperature superconducting steel jacket 6 arranged obliquely and at least one outer heat-insulating jacket 5. The outer heat-insulating jacket 5 is concentrically sleeved outside the high-temperature superconducting steel jacket 6. An outer heating zone 3 is formed between the outer wall of the high-temperature superconducting steel jacket 6 and the inner wall of the outer heat-insulating jacket 5. The inside of the high-temperature superconducting steel jacket 6 is a solid waste material channel, and the inside of the outer heating zone 3 is a high-temperature flue gas channel. The solid waste material in the high-temperature superconducting steel jacket 6 and the high-temperature flue gas in the outer heating zone 3 are non-contact. Along the conveying direction of the solid waste material, the high-temperature superconducting steel jacket 6 and the outer heat-insulating jacket 5 are arranged obliquely downward. The particulate matter mixed in the high-temperature flue gas falls to the bottom of the outer heating zone 3 under the action of its own gravity during the flow, and the outer heating zone 3 provides space for dust collection and dust settling. The desorption waste gas generated by heating the solid waste material in the high-temperature superconducting steel jacket 6 enters the off-line pretreatment gasification furnace for secondary combustion treatment under the action of negative pressure through a pipeline; when the desorption waste gas generated by heating the material in the high-temperature superconducting steel jacket 6 contains hydrogen fluoride, the waste gas is first subjected to defluorination treatment. Specifically, the calcium hydroxide generated by the reaction of quicklime and water reacts with fluoride ions to form insoluble calcium fluoride precipitate for defluorination treatment. The waste gas after defluorination treatment enters the off-line pretreatment gasification furnace for secondary combustion treatment under the action of negative pressure through a pipeline.

[0047] The fixed jacket desorption device includes a kiln body arranged horizontally and a high-temperature superconducting steel jacket 10 arranged parallel to the whole length inside the kiln body 9. A high-temperature flue gas channel is formed between the outer wall of the high-temperature superconducting steel jacket 10 and the inner wall of the kiln body 9. The inner cavity of the kiln body 9 is divided into five working section intervals along its length: a heating-up section, a low-temperature heat-insulating section, a high-temperature heating-up section, a high-temperature heat-insulating section, and a cooling-down section.

[0048] When the fixed jacket desorption device is adopted in the subsystem, the multi-source solid and hazardous waste energy resource utilization system with the "waste-free urban green energy valley" mode can be used for the roasting regeneration process of waste SCR catalysts, the roasting recovery process of waste metal packaging contaminants, and the sintering of solid waste-based building material components.

[0049] When the fixed jacket desorption device is used for the roasting and regeneration process of waste SCR catalysts, after the waste SCR catalysts go through the processes of soot blowing, ultrasonic cleaning, pickling, and reagent activation, they enter the fixed jacket desorption device and successively pass through five process sections of the fixed jacket desorption device, namely the heating section, the low-temperature insulation section, the high-temperature heating section, the high-temperature insulation section, and the cooling section, for the roasting process, generating high-temperature flue gas. The high-temperature flue gas is used to control the temperature of the thermal environment inside the fixed jacket desorption device between 600 - 700 °C. Finally, it leaves from the outlet of the fixed jacket desorption device. The entire roasting process takes 7 hours. During the roasting process, the moisture in the solution is removed in the form of water vapor in the heating section. After drying, the waste SCR catalysts are immersed in ammonium metavanadate reagent and ammonium metatungstate reagent. Both the ammonium metavanadate reagent and the ammonium metatungstate reagent react with oxygen to form the active components V2O5 and WO3 of the catalyst and remain on the surface and in the micropores of the catalyst. Then, they enter the fixed jacket desorption device again, and the active components V2O5 and WO3 are fixed in the SCR catalyst by the high-temperature flue gas. A small amount of ammonia is generated during the conversion process of ammonium metavanadate and ammonium metatungstate. The ammonia is introduced into an off-line pretreatment gasification furnace for secondary combustion treatment under negative pressure. After the flue gas from the roasted catalyst undergoes secondary denitrification treatment in the secondary denitrification device, it enters the steam generation device at the back end and is directly cooled to 200 °C in the steam generation device to generate saturated steam;

[0050] The conversion reactions during the above process are as follows:

[0051] 4NH4VO3 + 5O2 → 4V2O5 + 2H2O↑ + 4NH3↑

[0052] (NH4)6H2W 12 O 40 → 12WO3 + 4H2O↑ + 6NH3↑.

[0053] When the fixed jacket desorption device is used for the roasting and recovery process of waste metal packaging contaminants, the high-temperature flue gas is used to control the temperature of the thermal environment inside the fixed jacket desorption device between 800 - 900 °C, and it stays for 120 minutes. The waste gas generated in the furnace is introduced into an off-line pretreatment gasification furnace for secondary combustion treatment under negative pressure. After the flue gas from the roasted waste metal packaging contaminants undergoes secondary denitrification in the secondary denitrification device, it enters the steam generation device at the back end and is directly cooled to 200 °C in the steam generation device to generate saturated steam or superheated steam;

[0054] When the fixed jacket desorption device is used for the sintering of solid waste-based building material components, the temperature in the preheating section of the fixed jacket desorption device kiln body is 400 - 500 °C, the temperature in the sintering section is 1100 - 1120 °C, and the temperature in the cooling section is 300 - 400 °C. After the flue gas discharged from the fixed jacket desorption device is subjected to secondary denitrification by the secondary denitrification device, it enters the steam generation device at the back end and is directly cooled to 200 °C in the steam generation device to generate saturated steam or superheated steam.

[0055] When the rotary jacket desorption device is adopted in the subsystem, the waste-free urban green energy valley model multi-source solid and hazardous waste energy resource utilization and collaborative cascade utilization system can be used for the thermal desorption and dioxin removal process of municipal solid waste incineration fly ash, the activated regeneration process of waste activated carbon, and the anaerobic pyrolysis roasting process of lithium battery recycling.

[0056] When the rotary jacket desorption device is used for the thermal desorption and dioxin removal process of municipal solid waste incineration fly ash, the flow directions of the fly ash material in the high-temperature superconducting steel jacket and the high-temperature flue gas in the external heating zone are opposite to each other, and they stay for 20 - 40 minutes to complete the detoxification treatment. The waste gas generated by the thermal desorption of fly ash in the high-temperature superconducting steel jacket is introduced into the off-line pretreatment gasification furnace for secondary combustion treatment under negative pressure; the high-temperature flue gas after heat exchange with the fly ash material enters the secondary denitrification device for secondary denitrification treatment, and the denitrified flue gas enters the steam generation device at the back end and is directly cooled to 200 °C in the steam generation device to generate saturated steam or superheated steam.

[0057] When the rotary jacket desorption device is used for the activated regeneration process of waste activated carbon, the high-temperature flue gas is used to control the temperature of the thermal environment in the rotary jacket desorption device between 600 - 900 °C. At this temperature, the organic matter adsorbed in the waste activated carbon decomposes and ashes, and at the same time, saturated steam is introduced into the rotary jacket desorption device for pore reactivation of the waste activated carbon; the flow directions of the waste activated carbon material in the high-temperature superconducting steel jacket and the high-temperature flue gas in the external heating zone are opposite to each other, and the residence time is 50 - 60 minutes. The waste gas generated by the activated regeneration of waste activated carbon in the high-temperature superconducting steel jacket is introduced into the off-line pretreatment gasification furnace for secondary combustion treatment under negative pressure, and the high-temperature flue gas after heat exchange with the waste activated carbon enters the secondary denitrification device for secondary denitrification treatment, and the denitrified flue gas enters the steam generation device at the back end and is directly cooled to 200 °C to generate saturated or superheated steam.

[0058] When the rotary jacket desorption device is used in the anaerobic pyrolysis roasting process for lithium battery recycling, the thermal environment of the rotary jacket desorption device is controlled in an anaerobic state above 450 °C by using high-temperature flue gas. The waste lithium batteries after discharging, disassembling, and rough crushing are transported into the rotary jacket desorption device and pyrolyzed for 30 - 60 minutes to complete the volatilization of the electrolyte and the dissolution of the battery film. The waste gas generated by the pyrolysis roasting of the waste lithium batteries in the warm superconducting steel jacket is introduced into the intermittent defluorination device under negative pressure. After removing hydrogen fluoride from the pyrolysis waste gas, it enters the offline pretreatment gasification furnace for secondary combustion treatment; the flue gas after heat exchange during the pyrolysis roasting of the waste lithium batteries undergoes secondary denitrification in the secondary denitrification device and then enters the steam generation device at the back end, where it is directly cooled to 200 °C to generate saturated steam or superheated steam.

[0059] In the inner cavity of the tunnel-type high-temperature furnace, a preheating section, a sintering section, and a cooling section are sequentially arranged from the material inlet to the product outlet. When the tunnel-type high-temperature furnace is adopted in the subsystem, the waste-free urban green energy valley mode multi-source solid and hazardous waste energy resource utilization and collaborative cascade utilization system can be used for the sintering of solid waste-based building material components: the temperature of the preheating section in the tunnel-type high-temperature furnace is 400 - 500 °C, the temperature of the sintering section is 1100 - 1120 °C, and the temperature of the cooling section is 300 - 400 °C. The flue gas discharged from the tunnel-type high-temperature furnace undergoes secondary denitrification in the secondary denitrification device and then enters the steam generation device at the back end, where it is directly cooled to 200 °C to generate saturated steam or superheated steam.

[0060] The waste gas centralized collection and disposal system centrally treats the flue gas to make the flue gas meet the discharge standards. The treatment methods for the waste gas centralized collection and disposal system to centrally treat the flue gas include one or more of acid removal, activated carbon injection, Gore denitrification catalytic filter bag dust collection and denitrification (which can achieve three-stage denitrification of the flue gas), and electrostatic dust removal processes. According to the flue gas composition and treatment requirements, the treatment methods can be selectively used. According to the required flue gas discharge volume, one or several groups of acid removal, activated carbon injection, Gore denitrification catalytic filter bag dust collection and denitrification, and electrostatic dust removal process systems are opened as needed to achieve the optimal operation load of the waste gas treatment facilities and finally make the flue gas meet the discharge standards.

[0061] In the present invention, the multi-source solid and hazardous waste includes one or more of agricultural and forestry solid and hazardous waste, industrial solid and hazardous waste, urban solid and hazardous waste, mineral solid and hazardous waste, and marine solid and hazardous waste. The multi-source solid and hazardous waste can be classified into organic and inorganic categories after sorting.

[0062] In the present invention, the Green Energy Valley model follows the development path of organic solid waste energy utilization and inorganic solid waste resource utilization. It takes the high-temperature energy generated by the solid and hazardous waste pre-burning pretreatment energy generation and conversion system as the core, and the coupling between the industrial chains of solid waste resource utilization as the path. A series of core equipment and process technologies for energy conversion, cascaded utilization of waste heat, and hierarchical use of products for the comprehensive utilization of multiple solid and hazardous wastes have been developed, forming a closed-loop ecosystem for the hierarchical use of solid waste resources.

[0063] Through horizontal collaboration between industries, equipment sharing and process coupling between projects, the Green Energy Valley model realizes the system integration of the resource recycling of multiple solid and hazardous wastes, and has the complete production line capacity for the recycling of the above-mentioned multiple solid and hazardous wastes, not limited to a single process. The Green Energy Valley model can achieve zero fossil energy and zero or even negative carbon emissions. The lithium battery is first used for energy storage before disassembly, which can truly turn solid waste into treasure, realize waste treatment with waste, and play an important role in the construction of a waste-free city.

[0064] In the present invention, high-calorific value solid and hazardous waste materials are pre-burned through the solid and hazardous waste pre-burning pretreatment energy generation and conversion system to generate high-temperature flue gas as energy, which is used for the regeneration of solid waste products, resource utilization, and the energy consumption of the waste heat to produce steam for the energy industry. The biomass energy (i.e., the alternative fuel made from solid and hazardous wastes) is cascadedly utilized, and renewable solid and hazardous waste products such as waste activated carbon, waste SCR catalysts, and waste metal packaging are used to remove dioxins from municipal solid waste incineration fly ash through the energy cascade utilization and product coupling modification system. At the same time, the system is shared and extended to the extraction and recycling of waste activated carbon, waste SCR catalysts, waste metal packaging, waste lithium batteries, precious metals such as gold, silver, copper, and nickel, and the production of sintered and steam-cured building materials. The waste heat flue gas after passing through this system can be used to prepare high-temperature steam (saturated steam and superheated steam) through a steam generating device. This high-temperature steam can be used as secondary energy for the evaporation and crystallization of wastewater such as washed fly ash, the pore reformation of activated carbon, the revival of SCR catalysts, the extraction of precious metals, and the production of steam-cured building materials products. The pyrolysis gas generated in the high-temperature superconducting steel jacket is sucked under negative pressure by a high-temperature fan into the solid and hazardous waste pre-burning pretreatment energy generation and conversion system for incineration. After the flue gas is directly cooled to 200°C by the steam generating device, the waste gas is centrally collected and disposed of, and after meeting the standards, it is discharged. The remaining incineration residue participates in the co-disposal in a cement kiln.

[0065] In the present invention, the temperature of the high-temperature flue gas generated after the combustion of the off-line pretreatment gasifier and then passing through the cyclone dust collection system is 800 - 1150 °C. After this part of the high-temperature flue gas energy is utilized through the energy cascade utilization and product coupling modification system, there will be varying degrees of temperature attenuation. The attenuated flue gas generates saturated steam or superheated steam through the steam generating device. The saturated steam or superheated steam is output through the induced draft device and can be used as secondary energy for processes such as the evaporation and crystallization of washed fly ash, the re-punching of activated carbon, the revival of SCR catalysts, the heating for precious metal extraction, and the production of steam-cured building materials products. The flue gas after production is discharged into the waste gas centralized collection and disposal system, and the remaining or unused saturated steam or superheated steam in the entire system enters the waste heat power generation device for power generation.

[0066] The solid hazardous waste pre-burning pretreatment energy generation and conversion system, the cyclone dust collection system, the energy cascade utilization and product coupling modification system, and the waste gas centralized collection and disposal system are all communicatively connected to the digital platform control system and are controlled to operate through the digital platform control system. The present invention operates through the digital platform control system. This digital platform control system can realize the full life cycle supervision of solid hazardous waste after it enters the factory from aspects such as the raw material end entering the factory, warehousing, warehousing out, disposal and utilization, etc. It can also have a DCS control system on the production line, and can also perform carbon sink calculation and display carbon emission reduction data in real time. On the basis of meeting the daily production control, it can also realize functions such as solid hazardous waste trading, carbon sink accounting, and carbon footprint management.

[0067] In the present invention, the bottom slag generated from the solid hazardous waste after pre-burning pretreatment by the solid hazardous waste pre-burning pretreatment energy generation and conversion system is disposed of in a supplementary manner by the cement kiln co-processing. This system can operate independently throughout the year without being affected by the shutdown of the cement kiln. Its bottom slag participates in the cement kiln co-processing and is not treated by other methods such as landfilling. It can be free from the requirements of industry standards and specifications for the burning loss rate, enabling the solid hazardous waste to be pre-burned and pre-treated at any time when it enters the factory, greatly reducing the risk of storing solid hazardous waste.

[0068] The technical features not described in the present invention can be realized through the prior art and will not be elaborated here. The present invention is not limited to the above specific embodiments. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the essence of the present invention should also fall within the protection scope of the present invention.
