DETAILED DESCRIPTION

[0023] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive. Example

[0024] Please refer to the attached Figure 1 , 2As shown in Figures 3 and 4, a compressed biomass high-temperature gasification carbon reduction system includes a gasifier 1, which is made of high-temperature resistant alloy steel and lined with a heat-insulating material 101. The gasifier 1 is provided with a feed port 102 in the middle, a slag discharge port 103 at the bottom, and an air outlet 104 at the top. The feed port 102 is connected to a feed unit 2, the air outlet 104 is connected to a purification storage unit 3, and the slag discharge port is connected to a processing unit 5. The gasifier 1 is provided with a gasification reaction unit 4; the purification storage unit 3 includes a cyclone separation module 301 and a membrane separation module 302, and the cyclone separation module 301 is connected to a membrane separation module 302. It is connected to the gasifier 1, including a primary cyclone dust collector 307 and a secondary cyclone dust collector 308, which are connected to the gasifier 1 in sequence, and the bottoms of the primary cyclone dust collector 307 and the secondary cyclone dust collector 308 are connected to the gasifier 1 through a return pipe 309, and the end of the cyclone separation module 301 away from the gasifier 1 is connected to a membrane separation module 302 composed of a ceramic membrane 303 and a metal organic framework membrane 304, and the end of the membrane separation module 302 away from the cyclone separation module 301 is connected to a purified gas storage tank 305.

[0025] It should be noted that the purification storage unit 3 also includes a decomposition nozzle 306, which has 4 to 12 decomposition nozzles 306, and the decomposition nozzles 306 are distributed in an annular manner on the upper part of the gasifier 1 and face downward. In addition, the decomposition nozzles 306 form an angle of 45° to 90° with the vertical central axis of the gasifier 1, and the decomposition nozzles 306 are provided with an electric regulating valve 6. The 4 to 12 decomposition nozzles 306 can form a relatively uniform treatment area on the upper part of the gasifier 1, thereby effectively acting on the rising gas mixture. Its annular distribution and downward layout enable the material ejected from the decomposition nozzles 306 to fully contact and react with the rising impurity-containing gas. When the crude synthesis gas generated by the gasification reaction of the biomass raw material enters the upper area of ​​the furnace body, the high-temperature flames (1200-1500°C) from these nozzles quickly cover the material, starting the rapid drying and pyrolysis process. The high temperature of the flame causes the water inside the biomass to evaporate instantly, forming water vapor and participating in the subsequent reaction; at the same time, the pyrolysis reaction starts efficiently under the strong heat, and large molecular organic matter such as lignin and cellulose begin to break and decompose into small molecular hydrocarbons, aldehydes, phenols and other compounds. Due to the angle design of the nozzle, the flame impacts obliquely, forming a cyclone field in the upper space of the furnace, which increases the contact area and time between the material and the flame, ensuring that the pyrolysis reaction is carried out evenly and fully.

[0026] It should be noted that the ceramic membrane 303 in the membrane separation module 302 has the advantages of high temperature resistance, strong chemical stability, and good mechanical properties. Its regular porous structure can accurately screen impurities of different particle sizes. The metal organic framework (MOF) membrane has a highly ordered and adjustable pore structure, a large specific surface area, and a unique molecular recognition ability. In the purification of synthesis gas, for tar droplets and fine ash with a particle size greater than 0.1μm, the ceramic membrane can efficiently intercept them by microfiltration; the MOF membrane can preferentially adsorb polar small molecule impurities such as hydrogen sulfide and ammonia based on the difference in weak interactions between molecules, and achieve precise separation. The two work together to build a multi-dimensional impurity barrier, greatly improving the purity of synthesis gas.

[0027] It should be noted that the crude synthesis gas after pyrolysis by the decomposition nozzle 306 enters the cyclone separation module 301 from the gas outlet 104, and the first-level cyclone dust collector 307 in the cyclone separation module 301 separates large particles of dust and combustible substances, and returns them to the furnace body through the return pipe 309 to continue burning, while the remaining synthesis gas enters the second-level cyclone dust collector 308 for secondary separation, and the separated fine ash returns to the furnace through the return pipe 309 and falls to the bottom of the furnace body. The purified synthesis gas is finally obtained. The purified synthesis gas is purified by the mold separation module 302 and entered into the purified gas storage tank 305 for storage.

[0028] Please refer to the attached Figure 1 , 2 As shown in FIG. 5 , the processing unit 5 includes a slag pool 501 and a melting nozzle 502 . The slag pool 501 is connected to the bottom of the gasifier 1 , and an induction coil 503 is provided at the bottom and periphery of the slag pool 501 . It should be noted that the induction coils 503 arranged at the bottom and periphery of the slag pool 501 can generate an alternating magnetic field to drive forced convection of the slag, thereby achieving temperature and composition uniformity, breaking the slag temperature and composition stratification, ensuring that heavy metals migrate to specific areas for enrichment, enhancing the solidification stability of heavy metals, reducing the risk of leaching after the slag is cooled and solidified, and improving the quality of harmless treatment of fly ash.

[0029] It should be noted that there are 4 to 12 melting nozzles 502, and the melting nozzles are distributed in a ring shape at the bottom of the gasifier 1 and are directed upward. In addition, the melting nozzle 502 forms an angle of 45° to 90° with the vertical central axis of the gasifier 1, and an electric regulating valve 6 is provided on the melting nozzle 502.

[0030] It should be noted that 4 to 12 melting nozzles 502 can ensure a relatively comprehensive and uniform melting treatment of the materials at the bottom of the gasifier 1; their annular distribution at the bottom of the gasifier 1 and their upward orientation are conducive to making full use of the high-temperature molten material sprayed upward to fully contact and react with the falling materials, thereby improving the melting conversion efficiency of the materials; their design of an angle of 45° to 90° with the vertical central axis of the gasifier 1 can flexibly adjust the injection angle according to different material properties and gasification process requirements to achieve the best melting effect. When processing relatively loose and fluid materials, a larger angle can be selected to give the molten material a larger coverage area; while for relatively dense and refractory materials, the angle can be appropriately reduced to enhance the impact and penetration of the injection.

[0031] Please refer to the attached Figure 1 , 2 As shown in FIGS. 6 and 7 , the feeding unit 2 includes a feeding bin 201 , a metering screw 202 is provided at the bottom of the feeding bin 201 , and a compressor 203 is connected to one end of the metering screw 202 away from the feeding bin 201 , and the compressor 203 is connected to the gasifier 1 .

[0032] It should be noted that by adjusting the rotation speed of the metering screw 202, the flow rate of the biomass raw material output from the feed bin 201 can be accurately controlled, and the compressor 203 can not only reduce the volume of the raw material and increase its density, thereby being more conducive to the subsequent transportation and reaction in the gasifier 1, but also improve the physical structure of the raw material to a certain extent, so that it can more efficiently contact and react with the gasification agent in the subsequent gasification reaction.

[0033] Please refer to the attached Figure 1 , 2 As shown, the gasification reaction unit 4 includes a preheating platform 401, a gasifying agent nozzle 402 and a reaction nozzle 403. The preheating platform 401 is arranged in the middle of the gasifier 1, and a push rod 404 is arranged on the preheating platform 401. The gasifying agent nozzle 402 is arranged opposite to the preheating platform 401, and an electric regulating valve 6 is arranged on the gasifying agent nozzle 402. It should be noted that there are 4 to 12 reaction nozzles 403 , and the reaction nozzles 403 are distributed in a ring shape in the middle of the gasifier 1 and are horizontally oriented. In addition, the reaction nozzles 403 are provided with electric regulating valves 6 .

[0034] It should be noted that 4 to 12 reaction nozzles 403 can ensure a relatively comprehensive and uniform treatment of the material in the middle of the gasifier 1; their circular distribution in the middle of the gasifier 1 and their horizontal layout enable the material sprayed from the reaction nozzles 403 to achieve a relatively comprehensive and uniform coverage on the horizontal cross section in the middle of the gasifier 1, thereby being fully mixed and reacting with the biomass raw materials and other substances participating in the reaction in this area.

[0035] Please refer to the attached Figure 8 As shown, the gasifier 1 is also provided with a control unit 7, which includes a temperature control unit 8 and a feed control unit 9. The temperature control unit 8 includes a temperature sensor 801 and a PID controller 802. The temperature sensor 801 is installed at the upper part, the middle part and the bottom part of the gasifier 1; the PID controller 802 is electrically connected to the electric regulating valve 6 on the purification storage unit 3, the gasification reaction unit 4 and the processing unit 5, and the feed control unit 9 includes a weight sensor 901, a speed sensor 902 and a pressure sensor 903. The weight sensor 901 and the speed sensor 902 are installed at the metering screw 202 of the feed unit 2, and the pressure sensor 903 is installed on the compressor 203 of the feed unit 2, and the weight sensor 901, the speed sensor 902 and the pressure sensor 903 are all electrically connected to the control unit 7.

[0036] It should be noted that high-precision temperature sensors 801 are installed at different positions (upper, middle, and bottom) of the gasifier 1. These sensors can monitor the temperature of each area in real time and accurately, convert the temperature signal into an electrical signal and transmit it to the control unit 7. The control unit 7 uses a PID (proportional-integral-differential) controller 802 to adjust the fuel supply of each nozzle and the gasifier flow rate of the gasifier nozzle. When the sensor detects that the temperature deviates from the set value, the PID controller calculates the appropriate control amount based on factors such as the size of the deviation and the rate of change. If the temperature is too high, the controller will reduce the fuel supply of the corresponding nozzle; if the temperature is too low, the fuel supply will be increased, and the gasifier flow rate will be adjusted accordingly to ensure sufficient combustion and stable temperature within the set range. This precise temperature control can effectively ensure the complete decomposition of organic matter such as dioxins and tars, as well as the stable progress of the entire gasification reaction.

[0037] It should be noted that by installing a weight sensor 901 and a speed sensor 902 at the metering screw 202, the feed quality and feed speed of the biomass are monitored in real time. When the feed quality does not reach the preset range, the control unit 7 will adjust the speed of the metering screw 202. If the feed quality is lower than the set value, the control unit 7 will increase the speed of the metering screw 202 to allow more biomass to enter the compressor 203; otherwise, the speed will be reduced. At the same time, it also works in conjunction with the pressure sensor 903 of the compressor 203 to adjust the feed amount according to the pressure conditions in the compressor 203 to ensure that the compressor 203 operates at a suitable working pressure to prevent overload or insufficient feed.

[0038] The specific operation process of the present invention is as follows: The biomass raw material enters the feed bin 201, passes through the metering screw 202 below, reaches the set mass range, is sent to the compressor 203 for compression, and is pushed into the feed port 102. It stays on the preheating table 401 for an appropriate time (10~30S), and then is pushed into the furnace body through the push rod 404. The gasification agent nozzle 402 injects a high-speed gasification agent, and a pyrolysis and gasification reaction occurs under the high-temperature flame of the reaction nozzle 403 to generate a crude synthesis gas mainly composed of H2 and CO. The crude synthesis gas contains organic matter such as dioxins and tars, which rise to the upper part of the furnace body. There are 4~12 decomposition nozzles 306 around the upper part of the furnace body. Under the monitoring of the control unit 7, the temperature of the upper part of the furnace body is adjusted to maintain between 1150 and 1250℃. At this high temperature, dioxins carried by the feed, dioxins generated by gasification, tars, furans and other macromolecular organic matter generated by incomplete gasification reactions are completely decomposed to obtain a crude synthesis gas mainly composed of H2 and CO.

[0039] The crude synthesis gas enters the purification storage unit 3 from the gas outlet 104 at the top of the gasifier, passes through the first-stage cyclone dust collector 307 to separate large particles of dust and combustible substances, and returns to the furnace through the return pipe 309 to continue burning, while the remaining synthesis gas enters the second-stage cyclone dust collector 308 for secondary separation. The separated fine ash returns to the furnace through the return pipe 309 and falls to the bottom of the furnace body. The remaining synthesis gas passes through the membrane separation module 302 to further intercept tar droplets and fine ash, and adsorb polar small molecular impurities such as hydrogen sulfide and ammonia. The purified synthesis gas enters the purified gas storage tank 305 for use.

[0040] The inorganic substances that failed to undergo gasification reaction, together with the fly ash returned by the return pipe 309, enter the bottom of the gasifier. Under the action of the high-temperature flame (1300-2000°C) sprayed by the 4-12 annular melting nozzles arranged at the bottom of the furnace, they are kept in a molten state. They fall into the slag pool 501 through the slag discharge port at the bottom of the furnace. Induction coils 502 are arranged at the bottom and periphery of the slag pool 501 to generate an alternating magnetic field to drive the forced convection of the slag to achieve temperature and composition homogenization. After being quenched in the slag pool 501, a stable glassy solid is obtained.

[0041] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
