Description

Technical Field

[0001] This invention relates to an integrated technology for pyrolysis activation and modification, and in particular to an integrated system and method for pyrolysis activation and modification of solid raw materials. Background Technology

[0002] my country is a major economic power and a major producer of solid waste. Among the technologies for utilizing organic solid waste, pyrolysis or carbonization is a process that converts organic solid waste into pyrolytic char, pyrolytic oil, and pyrolytic gas through thermochemical conversion reactions. The gaseous products can be used for power generation, gas supply, or district heating. Pyrolytic oil can be upgraded into fuels and various chemicals. Pyrolytic char, through further processing, can be used to prepare charcoal fertilizer, soil conditioner, activated carbon, and catalysts. Traditional activated carbon preparation employs a two-step method: carbonization and activation. Traditional carbonization and activation reactors include fixed beds, moving beds, rotary kilns, and rake furnaces. The main problems with these methods are gas short-circuit wall flow, poor gas-solid mixing, uneven bed temperature, unstable product quality, large footprint, high energy consumption, and heavy pollution. Fluidized beds are increasingly used due to their good gas-solid mixing, uniform bed temperature, stable product quality, compact structure, and energy efficiency. However, their application in the carbonization and activation fields is limited, and there are still many shortcomings in fluidized bed design, structural layout, component configuration, and process optimization, resulting in high energy consumption and poor product quality.

[0003] Indirect heating pyrolysis technology has developed rapidly both domestically and internationally in recent years, but it mainly focuses on producing high-calorific-value pyrolysis gas, resulting in low-quality pyrolysis carbon. The process of achieving carbonization through pyrolysis and then efficiently activating it to prepare activated carbon is still in the exploratory stage. There is an urgent need to develop processes and equipment for pyrolysis, carbonization, activation, and modification to efficiently and cost-effectively prepare high-value activated carbon, ensuring its adsorption performance, particle strength, and thermal stability to meet the needs of society and the market. Summary of the Invention

The pyrolysis gas condensation and purification unit is connected to the cyclone reactor. The cyclone reactor can be placed completely outside the pyrolysis unit or partially inside the pyrolysis unit. When the cyclone reactor is placed outside the pyrolysis unit, the solid output end of the cyclone reactor is connected to the pyrolysis unit, and the gas output end of the cyclone reactor is connected to the pyrolysis gas condensation and purification unit.

[0007] A further optimization scheme is the aforementioned integrated system for pyrolysis, activation and modification of solid raw materials. The pyrolyzer is connected to the rapid fluidized bed activator unit through a bottom material sealing section and a circulation section. The material sealing section can adopt a sloping groove material sealing or a non-mechanical valve seal of type L, J, U, etc. The circulation section can adopt a non-mechanical valve seal of type L, J, U, etc. The screw dryer and the pyrolyzer are equipped with heating jackets.

[0008] A further optimization scheme is the aforementioned integrated system for pyrolysis activation and modification of solid raw materials. The rapid fluidized bed activator unit includes, in sequence, a riser pipe, a settling tank, and a downcomer pipe. The riser pipe and the settling tank are connected, and the settling tank and the downcomer pipe are connected. The riser pipe and the settling tank have different dimensions in the horizontal direction. The riser pipe is vertically and eccentrically arranged in the settling tank. The top of the riser pipe is at least 20 cm away from the top of the settling tank. The distance between the outer wall of the riser pipe and the downcomer pipe is 5-10 cm. The angle between the inclined groove at the bottom of the settling tank and the horizontal direction is 50-70 degrees. A downcomer activated carbon discharge pipe (20) is set at the bottom of the downcomer pipe.

[0009] A further optimization scheme is the aforementioned integrated system for pyrolysis activation modification of solid raw materials. The gas in the air inlet unit includes water vapor, hot flue gas, air, or other hot gases. The air inlet unit is connected to the rapid fluidized bed activator unit at the bottom of the riser pipe.

The activated carbon discharge unit includes a high-level activated carbon discharge tank, a low-level activated carbon discharge tank, and a downflow activated carbon discharge pipe. Multiple discharge ports and discharge tanks can be arranged in the vertical direction of the riser pipe.

[0010] A further optimization scheme is the aforementioned integrated system for pyrolysis activation modification of solid raw materials. The solid raw material feeding unit includes a conveyor and a mixing feeder, which are connected together. The mixing feeder consists of a hopper, valves, and rollers. The rollers are hollow as a whole, with a hollow central shaft that runs through the front and back. The roller air inlet pipe enters the inner cavity at the center of the shaft. The roller air inlet pipe is connected to the air outlet of the screw dryer jacket. The air outlet pipe in the inner cavity of the roller discharges at the center of the shaft at the other end. After purification, the liquid is vented. The condensate is discharged through the holes on the roller surface at the bottom of the roller. After purification, the water is recycled.

[0011] This invention is an integrated pyrolysis-activation modification system for solid raw materials, based on a sloping trough moving bed and a rapid fluidized bed. It utilizes hot flue gas from pyrolysis gas combustion and steam to perform integrated pyrolysis-activation treatment on solid raw materials. The hot flue gas and steam enter the riser of the fluidized bed activator. Part of the carbon-based particles enters the activated carbon discharge unit as product output, while the other part enters the pyrolyzer via a settling tank, downcomer, and circulation section. The activation tail gas enters a primary cyclone separator and a secondary cyclone separator. After gas-solid separation, the solids enter the material sealing pipe, then pass through the cyclone reactor into the pyrolyzer. The carbon-based material circulates, transferring heat from the activator's internal reactor to the pyrolyzer. The activation tail gas from the secondary cyclone separator is divided into two streams: one stream enters the steam generator to produce steam using the heat from the activation tail gas, and the other stream enters the heating jacket of the pyrolyzer. The pyrolyzer provides indirect heating, and the hot gas from the pyrolyzer jacket enters the screw dryer jacket. The gas from the screw dryer jacket then enters the hollow rollers of the feeding unit for pre-drying of the raw materials. This achieves efficient heating by combining cascaded heat utilization with indirect and direct heating, improving the system's thermal efficiency. At the same time, the rapid fluidized bed activator provides uniform temperature and stable quality of the carbon-based materials. The device has a compact structure, small footprint, low energy consumption, and most nitrogen, sulfur, and chlorine pollutants are solidified in the carbon-based materials, thereby reducing pollutant emissions. Compared with traditional carbonization activation technology, it has greater advantages and a broader market prospect.

[0012] This invention has positive effects:

[0013] (1) The system of the present invention can simultaneously complete the drying, pyrolysis and activation of solid raw materials in the same device. The combination of external jacket heating and internal heating of hot bed material circulation realizes energy cascade utilization, greatly improves pyrolysis and activation efficiency, reduces pollutant emissions, reduces energy consumption, reduces floor space, and improves carbon-based material yield through segmented heat treatment. The rapid fluidized bed activator has good gas-solid mixing, uniform bed temperature, and stable product quality, and has huge technical advantages.

[0014] (2) The activation tail gas generated by the rapid fluidized bed activator passes through the first-stage cyclone separator and the second-stage cyclone separator. The solid enters the material sealing pipe and returns to the pyrolyzer through the cyclone reactor. The heat is transferred from the activator to the pyrolyzer. The hot gas from the cyclone separator enters the steam generator and the heating jacket of the pyrolyzer. The gas from the heating jacket of the pyrolyzer enters the jacket of the screw dryer. The gas from the jacket of the screw dryer enters the feeding unit for indirect preheating, realizing the cascade utilization of energy. The steam is produced and used by the user as the activation gas medium, fluidizing gas and material sealing conveying gas, which are sent to the pyrolyzer and activator respectively. This improves the system efficiency and bed material circulation effect and improves the quality of carbon-based materials.

[0015] (3) The pyrolyzer adopts a sloping trough moving bed structure with fluidization characteristics, which improves the solid conveying performance, improves the gas-solid mixing effect, and reduces energy consumption. The solid particles of the pyrolyzer flow to the material sealing section, and are then blown to the rapid fluidized bed activator by the material sealing conveyor gas. After activation, part of the solid particles are sent out by the activated carbon discharge unit, and the other part returns to the pyrolyzer after passing through the air lifting pipe, settling tank, downflow pipe and circulation section. The bed material circulation improves system efficiency, extends residence time, reduces energy consumption and improves product quality.

[0016] (4) The solid raw material feeding unit is continuously fed by a conveyor and a mixing feeder. The mixing feeder consists of a hopper, valves and rollers. The rollers are hollow as a whole, and the central shaft is hollow. The hollow shaft is connected from front to back. The roller air inlet pipe enters the inner cavity at the center of the shaft. The roller air inlet pipe is connected to the air outlet of the screw dryer jacket. The inner cavity air outlet pipe of the roller is at the center of the shaft at the other end. After purification, it is vented. The condensate is discharged through the holes on the roller surface at the bottom of the roller. After purification, the water is recycled.

[0017] (5) The cyclone reactor is the junction of solids and pyrolysis gas after gas-solid separation in the secondary cyclone separator of the activator. The adsorption and catalytic effect of solid carbon particles can efficiently degrade pyrolysis oil and remove pollutants and impurities from pyrolysis gas. The cyclone reactor achieves material sealing isolation through the material sealing pipe and the secondary cyclone separator. The solid carbon particles are transported and sealed through the feed pipe below it. The gas outlet of the cyclone reactor is connected to the pyrolysis gas condensation and purification unit. The cyclone reactor can be placed completely outside the pyrolysis unit or partially inside the pyrolysis unit. The arrangement is flexible. When the cyclone reactor is set outside the pyrolysis unit, the solid output pipe of the cyclone reactor is connected to the pyrolysis unit, and the gas output end of the cyclone reactor is connected to the pyrolysis gas condensation and purification unit. The design of the cyclone reactor and the arrangement of the material sealing mechanism effectively reduce pollutant emissions and improve the quality of carbon-based materials.

The solid raw material feeding unit includes a conveyor 13 and a mixing feeder 12. The solid raw material feeding unit conveys the solid raw material to the screw dryer 10 for drying, and then enters the pyrolyzer 1 for pyrolysis. The pyrolyzed carbon passes through the material sealing section 9 and is blown by steam into the rapid fluidized bed activator unit for activation, thereby preparing activated carbon and other carbon-based materials. The rapid fluidized bed activator unit includes a riser 2, a settling tank 3, and a downcomer 4. The bottom of the downcomer has an activated carbon discharge pipe 20. The riser 2 is vertically arranged with a high-level activated carbon discharge tank 14 and a low-level activated carbon discharge tank 15. The air inlet unit 16 is connected to the rapid fluidized bed activator unit at the bottom of the riser 2. The hot flue gas after the pyrolysis gas and other fuel gas are mixed and burned with air enters the rapid fluidized bed activator unit through the air inlet unit. Water vapor is used as the activation gas medium, fluidizing medium, and material sealing conveying gas, and enters the integrated pyrolysis activation modification system through the air inlet unit 16, the pyrolyzer 2, the circulation section 5, the material sealing section 9, and the material sealing pipe 18 on the cyclone reactor 6, respectively.

[0023] Pyrolysis unit 1 is connected to circulation section 5, material sealing section 9, and rapid fluidized bed activator unit. Solids in pyrolysis unit 2 are fed by gravity, fluidization, pneumatic conveying, and material sealing mechanisms. They enter the riser pipe 2 of the rapid fluidized bed activator unit via material sealing section 9. In riser pipe 2, the solids are blown by hot gas to settling tank 3, then into downcomer pipe 4, and finally circulate back to pyrolysis unit 2 via circulation section 5. Activation exhaust gas enters primary cyclone separator 7 and secondary cyclone separator 8 via riser pipe 2. Solids from primary cyclone separator 7 and secondary cyclone separator 8 then enter... The material sealing pipe 19 leads into the cyclone reactor 6 and then back to the pyrolyzer. The activated tail gas from the secondary cyclone separator 8 enters the jacket of the steam generator 17 and the pyrolyzer 1. The gas from the jacket of the pyrolyzer 1 enters the jacket of the screw dryer 10. The gas from the jacket of the screw dryer 10 enters the roller 21 of the solid raw material feeding unit to pre-dry the solid raw materials, realizing smooth circulation of bed material and cascade utilization of energy, achieving solidification of pollutants, greatly improving system efficiency, reducing pollutant emissions, and reducing energy consumption.

[0024] The riser pipe 2 and settling tank 3 of the rapid fluidized bed activator unit are connected, and the settling tank 3 and downcomer pipe 4 are connected. The riser pipe 2 and settling tank 3 have different dimensions in the horizontal direction. The riser pipe 2 is vertically and eccentrically arranged in the settling tank 3. The top of the riser pipe 2 is at least 20 cm away from the top of the settling tank 3. The distance between the outer wall of the riser pipe 2 and the adjacent pipe wall of the downcomer pipe 4 is 5-10 cm. The angle between the bottom slope of the settling tank 3 and the horizontal direction is 50-70 degrees. A downcomer activated carbon discharge pipe 20 is set at the bottom of the downcomer pipe. The riser pipe 2 is equipped with a high-level activated carbon discharge tank 14 and a low-level activated carbon discharge tank 15 to achieve efficient circulation of solids, flexible discharge, and precise control of the quality of carbon-based materials. The activated carbon discharge unit includes a high-level activated carbon discharge tank 14, a low-level activated carbon discharge tank 15, and a downcomer activated carbon discharge pipe 20. Multiple activated carbon discharge tanks can be arranged vertically on the riser pipe 2.

[0025] The solid raw material feeding unit includes a conveyor 13 and a mixing feeder 12. The conveyor 13 transports solid raw materials to the mixing feeder 12 for mixing, conveying, and extrusion. The mixing feeder 12 consists of a hopper, valves, and rollers 21. The hopper holds the solid raw materials. Multiple valves alternately open and close to achieve continuous positive pressure feeding. The rollers 21 extrude and transport the solid raw materials, improving the density and flowability of the solid raw materials and ensuring stable feeding. The rollers 21 are hollow as a whole, with a hollow central shaft that runs through the front and back. The air outlet of the screw dryer 10 jacket is connected to the air inlet pipe of the rollers 21. The air inlet pipe of the rollers 21 enters the inner cavity at the center of the shaft, and the air outlet pipe of the inner cavity of the rollers 21 is at the center of the shaft at the other end. After purification, the condensate is discharged through the holes on the surface of the rollers 21 at the bottom. The purified water is recycled.

[0026] Its working process is as follows: solid raw materials enter from the feeding unit, are mechanically transported by conveyor 13, mixed by mixing feeder 12, squeezed by roller 21, and continuously positive pressure fed by alternating opening and closing of multiple valves; the solid raw materials enter the screw dryer 10 for drying, and then enter the inclined trough moving bed for pyrolysis. The pyrolysis gas mainly consists of CO2, H2O, CO, H2, C2, C3, etc., and passes through the cyclone reactor 6, the pyrolysis gas condensation and purification unit 11 in sequence, and is sent into the pyrolysis gas combustion unit 18 by the induced draft fan. After screw extrusion conveying, gravity conveying, steam fluidization, and steam blowing, the solid raw materials are continuously fed into the screw dryer 10 for drying, and then into the inclined trough moving bed for pyrolysis. The pyrolytic carbon is fed from the material sealing section 9 into the riser pipe 2 of the rapid fluidized bed activator unit. The hot flue gas and steam generated by the combustion of pyrolysis gas and other fuel gases activate the pyrolytic carbon. Chemical activators can be added at the top of the silo in the solid raw material feeding unit to improve the activation effect. A portion of the activated carbon is removed from the activated carbon discharge unit, including the high-level activated carbon discharge tank 14, the low-level activated carbon discharge tank 15, and the downflow activated carbon discharge pipe 20. Another portion of the activated carbon enters the downflow pipe 4 through the settling tank 3 and returns to the pyrolyzer 1 through the circulation section 5, achieving efficient and smooth circulation of the bed material and improving system efficiency. The activated tail gas sequentially passes through a primary cyclone separator 7 and a secondary cyclone separator 8. The solids from the primary and secondary cyclone separators 7 and 8 enter the material sealing pipe 19, and then enter the cyclone reactor 6, before returning to the pyrolysis unit. The activated tail gas from the secondary cyclone separator 8 enters the jacket of the steam generator 17 and the pyrolysis unit 1. The gas from the jacket of the pyrolysis unit 1 enters the jacket of the screw dryer 10. The gas from the jacket of the screw dryer 10 enters the roller 21 of the solid raw material feeding unit to pre-dry the solid raw materials. The roller 21 is hollow as a whole, with a hollow central shaft. The spindle is continuous from front to back. The air outlet of the screw dryer 10 jacket is connected to the air inlet pipe of the roller 21. The air inlet pipe of the roller 21 enters the inner cavity at the center of the shaft. The air outlet pipe of the inner cavity of the roller 21 is at the center of the shaft at the other end. After purification, the liquid is released. The condensate is discharged from the bottom of the roller 21 through the holes on the surface of the roller 21. The purified water is recycled. In summary, this invention greatly improves the system efficiency, increases the carbon yield and quality, achieves pollutant solidification, reduces pollutant emissions, and lowers energy consumption through process optimization, reactor structure improvement, segmented heat treatment arrangement, smooth circulation of bed material, and energy cascade utilization.
