Description

Technical Field

[0001] The present invention relates to the technical field of methanol synthesis, and specifically, to a biomass-coupled green hydrogen-based green methanol production device and method. Background Art

[0002] At present, most methanol is used as a standardized raw material in industries such as energy, fuel, and chemicals. Using carbon dioxide generated by high-carbon emission industries as a carbon resource to obtain methanol through chemical conversion can not only reduce carbon dioxide emissions, but also use the carbon dioxide emitted during the process as a carbon resource, which can replace the consumption of coal, ensure energy security, reduce water resource consumption and pollution emissions, and has a significant role in alternative emission reduction.

[0003] Regarding the biomass-coupled green hydrogen-based green methanol production device, there are many existing technologies, for example: Chinese Patent Publication No. CN1696089A discloses a methanol synthesis tower. A central tube is arranged at the axis position inside the shell cavity. The upper and lower ends of the reaction tube bundles arranged axially inside the shell are respectively fixedly sealed in the corresponding insertion holes on the upper and lower tube sheets. The inner head with a discharge hole structure at the bottom end is fixedly sealed on the bottom surface of the lower tube sheet to form a lower floating head. And expansion gaps are left between the circumferences of the lower tube sheet and the inner head and the inner wall of the shell. This methanol synthesis tower overcomes the temperature difference stress between the tube bundle and the shell and solves the problem of high-temperature sealing of the reaction part inside the shell. Moreover, it is convenient to replace the catalyst filler, has a simple structure, and a low manufacturing cost.

[0004] However, in the actual use process, there are still some problems to be solved urgently: 1. Currently, a shell-and-tube heat exchanger is used inside the methanol synthesis tower for heat exchange and cooling. The equipment structure is complex, resulting in a large installation difficulty. During the equipment installation process, the shell-and-tube heat exchanger requires a large space, which is demanding on the plant area and space layout, increasing the site construction cost and the difficulty of space planning. At the same time, the shell-and-tube heat exchanger has problems such as low fluid velocity in the shell side and limited heat transfer coefficient. When dealing with high-load reaction heat, it is impossible to achieve rapid and efficient heat exchange, affecting the temperature uniformity inside the synthesis tower, resulting in local overheating or overcooling phenomena, and further affecting the catalyst activity and methanol synthesis efficiency; 2. In the existing methanol synthesis process, the catalyst is usually in a static filling state, relying only on the natural diffusion of the reaction gas to contact the catalyst. This static reaction mode leads to a limited contact area and short contact time between the gas-solid two phases. It is difficult for the reaction gas to fully interact with the active sites of the catalyst, resulting in low catalytic efficiency.

[0005] Therefore, a biomass-coupled green hydrogen-based green methanol production device and method are proposed. Summary of the Invention

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] One of the purposes of the present invention is to refer to Figures 1-8As shown, a biomass-coupled green hydrogen to green methanol device is provided, including a methanol synthesis reactor 100, a green hydrogen preparation device 200, and a biomass gasification tower 300. The methanol synthesis reactor 100 includes a housing 101 and a cover 102. A methanol outlet 106 is provided below the housing 101, and a skirt support 109 is provided at the bottom of the housing 101. A sealing strip 110 is provided between the housing 101 and the cover 102. An intake valve 103 is provided at the top of the cover 102. The green hydrogen preparation device 200 and the biomass gasification tower 300 are connected to both sides of the intake valve 103 through gas pipes. Thermocouples 104 and pressure gauges 105 are provided on both sides of the top of the cover 102. A gas regulation assembly 600 is provided inside the cover 102. The gas regulation assembly 600 includes a distribution box 601 provided below the intake valve 103. A distribution plate 602 is provided at the bottom of the distribution box 601. A plurality of through holes are formed on the surface of the distribution plate 602. A leakage plate 603 is provided above the distribution plate 602. A blocking block 604 is provided at the bottom of the leakage plate 603. The blocking block 604 is adapted to the through holes. A temperature control assembly 400 is provided inside the housing 101. The temperature control assembly 400 is used to adjust the temperature inside the methanol synthesis reactor 100. A catalyst box 107 is provided above the temperature control assembly 400. A stirring assembly 500 is provided inside the catalyst box 107. When the temperature control assembly 400 adjusts the temperature inside the methanol synthesis reactor 100, it drives the stirring assembly 500 to stir the inside of the catalyst box 107, so that the catalysts inside the catalyst box 107 are mixed. A heating strip 111 is provided near the bottom of the housing 101. The heating strip 111 heats the inside of the methanol synthesis reactor 100.

[0022] During the cooling process of existing methanol equipment, the methanol production process is an exothermic reaction. Heat exchange and cooling are carried out through a shell-and-tube heat exchanger, which is rather troublesome and occupies a large area. Therefore, the temperature control component 400 includes a water inlet pipe 401 provided on one side of the housing 101. The water inlet pipe 401 includes a first water inlet pipe and a second water inlet pipe. The end of the water inlet pipe 401 penetrates through the housing 101 and a temporary storage box 402 is provided at the end. A spiral pipe 403 is connected to the bottom of the temporary storage box 402. The free end of the spiral pipe 403 penetrates through the water inlet pipe 401 to the outside. A turbine fan blade 404 is provided inside the temporary storage box 402. When the water body inside the water inlet pipe 401 enters the inside of the temporary storage box 402, the turbine fan blade 404 buffers the impact force of the water body. When it is necessary to cool the inside of the methanol synthesis reactor 100, cold water is diverted to the first water inlet pipe through a water pump. The cold water in the first water inlet pipe enters the inside of the temporary storage box 402. During the entry process, the water flow impacts the side wall of the turbine fan blade 404, and the turbine fan blade 404 rotates under the impact force of the water flow. By converting the impact force of the water flow into the power for the rotation of the turbine fan blade 404, the water body entering the inside of the temporary storage box 402 flows out through the spiral pipe 403. Through the adjustment of the cooling water, it is prevented that the temperature is too high, resulting in the reduction of the catalyst activity and the shortening of the service life. At the same time, side reactions caused by too high temperature are avoided, which affects the yield and quality of methanol. Since the spiral pipe 403 is spiral, the flow rate of the water flow decreases when passing through the spiral pipe 403, thereby increasing the time for the water flow to stay inside the housing 101, and thus improving the cooling effect; When increasing the temperature inside the methanol synthesis reactor 100, the temperature of the methanol synthesis reactor is 250 °C. In order to facilitate the rapid adjustment of the temperature inside the methanol synthesis reactor 100, therefore, heating is carried out through the heating strip 111, and at the same time, boiling water is filled into it through the second water inlet pipe, so as to rapidly increase the temperature inside the methanol synthesis reactor 100.

[0023] During the methanol production process, in order to increase the catalytic efficiency of the catalyst and improve the methanol production, a boss 108 is provided inside the catalyst box 107. The boss 108 is trapezoidal in shape. A connecting shaft 501 is provided at the top of the turbine fan blade 404. The connecting shaft 501 passes through the boss 108 and a rotating rod 502 is provided at the top. A stirring plate 503 is provided at the top of the rotating rod 502. The stirring plate 503 rotates coaxially with the connecting shaft 501. When cooling the inside of the methanol synthesis reactor 100 during the methanol production process, cold water in the first water inlet pipe enters the temporary storage box 402 and impacts the turbine fan blade 404. The turbine fan blade 404 rotates under the impact force. When the turbine fan blade 404 rotates, it drives the connecting shaft 501 to rotate coaxially. When the connecting shaft 501 rotates, it drives the stirring plate 503 to rotate through the rotating rod 502. The stirring plate 503 rotates while fitting on the inner wall of the catalyst box 107. When the stirring plate 503 rotates, it stirs the catalyst. Stirring can make the reaction materials flow more quickly around the catalyst, reduce the diffusion resistance of the reactants on the catalyst surface, enable the reactants to reach the catalyst active center more timely, and at the same time promote the products to leave the catalyst surface in time, avoiding the accumulation of products near the catalyst and inhibiting the reaction. By stirring, the syngas can be fully contacted with the catalyst particles suspended in the liquid, significantly improving the conversion rate of the syngas; At the same time, when the stirring plate 503 rotates, it is at the top of the boss 108, thereby reducing the friction between the bottom of the stirring plate 503 and the catalyst box 107. When the stirring plate 503 rotates, it stirs the catalyst on both sides of the boss 108, avoiding the rolling friction between the catalyst and the bottom of the catalyst box 107, resulting in a reduction in the volume of the catalyst, thereby increasing the service life of the catalyst.

[0024] During the process of the stirring plate 503 stirring the catalyst, in order to avoid excessive thrust of the rotating stirring plate 503 on the catalyst, resulting in excessive extrusion force between the catalysts and causing deformation, affecting the catalytic efficiency, a torsion spring 504 is provided between the rotating rod 502 and the stirring plate 503. When the stirring plate 503 rotates, it stirs the catalyst inside the catalyst box 107. The stirring plate 503 rotates on the top of the rotating rod 502 under the resistance of the catalyst. The stirring plate 503 is arc-shaped. When the stirring plate 503 rotates, it fits on the inner wall of the catalyst box 107. When the stirring plate 503 rotates, the stirring plate 503 pushes the catalyst filled inside the catalyst box 107. The catalysts roll and rub against each other under the thrust. When the relative acting force is too large, the rotating rod 502 rotates on the surface of the rotating rod 502 and the torsion spring 504 is deformed at this time, thereby avoiding excessive thrust during the stirring process of the stirring plate 503 and maintaining the state of the catalyst.

[0025] Working principle of the green hydrogen generator 200; Input electrical energy into the proton exchange membrane electrolytic water hydrogen production device. In the electrolytic cell, control the electrolytic voltage to be 1.8V and the current density to be 2500A / m² to obtain green hydrogen with a purity of 99.99%.

[0026] Working principle of biomass gasification tower 300: Collect wood chips as biomass raw materials, and after crushing, the particle size reaches below 2 mm. In the dryer, the temperature is raised to 100 °C of the methanol synthesis reactor, and the water content is reduced to 5%. Pellets with a diameter of 4 mm and a length of 8 mm are made through a pelletizer, and the pretreated wood chip pellets are sent into the fluidized bed gasification furnace, controlling the gasification temperature at 900 °C and the gasification agent flow rate at 800 m³ / h. The volume fraction of CO in the generated raw syngas is 35%, H2 is 30%, CO2 is 15%, and CH4 is 3%. The raw syngas enters the new desulfurization tower and is desulfurized using a new desulfurization agent, with a desulfurization efficiency reaching 99% and the sulfur content reduced to below 5 mg / m³. It enters the upgraded decarbonization tower, and through the optimized decarbonization process, the CO2 content in the gas after decarbonization is reduced to below 2%. After passing through an advanced pressure swing adsorption device, the total impurity content is lower than 0.5%; Working principle of methanol synthesis reactor 100: After mixing the purified syngas and green hydrogen in a ratio of H2 / CO + CO2 molar ratio of 2.5, it is sent into an isothermal methanol synthesis reactor, and the reaction is carried out under the conditions of a reaction temperature of 230 °C and a reaction pressure of 6 MPa; When the methanol synthesis reactor is working, the green hydrogen and the purified synthesizer are input into the intake valve 103 in proportion, and the mixed gas enters through the distribution box 601. There is a distribution plate 602 at the bottom of the distribution box 601, and through holes are opened on the surface of the distribution plate 602 to ensure that there is a certain buffer space after the reaction gas is discharged and the dispersion is more uniform. The size of the through holes directly affects the flow rate of the reaction gas, thereby controlling the reaction rate. There is a cylinder 605 on the inner wall of the distribution box 601, and a sliding rod 606 is slidably arranged on the inner wall of the cylinder 605. There is a compression spring 607 between the cylinder 605 and the sliding rod 606, and the end of the sliding rod 606 is fixed on the top of the leakage plate 603. When it is necessary to accelerate the reaction rate, the through holes can be appropriately increased to increase the flow rate of the reaction gas, so that more reactants participate in the reaction; if the reaction rate is too fast, side reactions or temperature runaway may be caused, then the through holes are reduced to reduce the flow rate of the reaction gas and stabilize the reaction process. In the initial stage of methanol synthesis, the through holes are increased to quickly establish the reaction system; in the later stage of the reaction, the through holes are appropriately reduced to maintain a stable reaction rate and product quality. When adjusting the size of the through holes, the output end of the control cylinder 608 is moved downward in the vertical direction, and the output end presses on the top of the sliding rod 606. The sliding rod 606 slides on the inner wall of the cylinder 605, and when the sliding rod 606 moves, it drives the leakage plate 603 to move downward in the vertical direction. A blocking block 604 provided at the bottom of the leakage plate 603 blocks the through holes provided on the surface of the distribution plate 602. Since the blocking block 604 is conical, the flow rate of the mixed gas flow is controlled in real time through the matching degree between the blocking block 604 and the through holes, thereby ensuring the stability of the reaction process.

[0027] During specific use, when it is necessary to cool the inside of the methanol synthesis reactor 100, cold water is diverted to the first water inlet pipe through a water pump. The cold water in the first water inlet pipe enters the inside of the temporary storage tank 402. During the entry process, the water flow impacts the side wall of the turbine fan blade 404, and the turbine fan blade 404 rotates under the impact force of the water flow. By converting the impact force of the water flow into the driving force for the rotation of the turbine fan blade 404, the water body entering the inside of the temporary storage tank 402 flows out through the spiral pipe 403. Through the regulation of the cooling water, it is prevented that the catalyst activity decreases and the service life is shortened due to excessive temperature, and at the same time, side reactions caused by excessive temperature are avoided, which affects the yield and quality of methanol. Since the spiral pipe 403 is spiral, the flow rate of the water flow decreases when passing through the spiral pipe 403, thereby increasing the time for the water flow to stay inside the housing 101, thus improving the cooling effect; When cooling the inside of the methanol synthesis reactor 100 during the methanol production process, the cold water in the first water inlet pipe enters the inside of the temporary storage tank 402 and impacts the turbine fan blade 404. The turbine fan blade 404 rotates under the impact force. When the turbine fan blade 404 rotates, it drives the connecting shaft 501 to rotate coaxially. When the connecting shaft 501 rotates, it drives the stirring plate 503 to rotate through the rotating rod 502. The stirring plate 503 rotates while fitting against the inner wall of the catalyst box 107. When the stirring plate 503 rotates, it stirs the catalyst. Stirring can make the reaction materials flow more quickly around the catalyst, reduce the diffusion resistance of the reactants on the catalyst surface, enable the reactants to reach the catalyst active center more timely, and at the same time promote the products to leave the catalyst surface in time, avoiding the accumulation of products near the catalyst and inhibiting the reaction. By stirring, the syngas can be fully contacted with the catalyst particles suspended in the liquid, which can significantly improve the conversion rate of the syngas; When the stirring plate 503 rotates, the stirring plate 503 pushes the catalyst filled inside the catalyst box 107. The catalysts roll and rub against each other under the thrust. When the relative acting force is too large, the rotating rod 502 rotates on the surface of the rotating rod 502 and the torsion spring 504 is deformed at this time, thereby avoiding excessive thrust during the stirring process of the stirring plate 503 and maintaining the state of the catalyst; By controlling the output end of the cylinder 608 to move downward in the vertical direction, the output end presses on the top of the sliding rod 606. The sliding rod 606 slides on the inner wall of the cylinder 605. When the sliding rod 606 moves, it drives the leakage plate 603 to move downward in the vertical direction. The blocking block 604 provided at the bottom of the leakage plate 603 blocks the through holes provided on the surface of the distribution plate 602. Since the blocking block 604 is conical, therefore, the flow rate of the mixed gas flow is controlled in real time through the adaptability between the blocking block 604 and the through holes, thereby ensuring the stability of the reaction process.

[0028] The second object of the present invention is to provide a processing method for a biomass-coupled green hydrogen to green methanol device, including the biomass-coupled green hydrogen to green methanol device in any one of the above, comprising the following steps: S1. The water pump diverts the cold water to the first water inlet pipe. The cold water in the first water inlet pipe enters the interior of the temporary storage tank 402. During the entry process, the water flow impacts the side wall of the turbine fan blade 404. The turbine fan blade 404 rotates under the impact force of the water flow. By converting the impact force of the water flow into the driving force for the rotation of the turbine fan blade 404, the water body entering the interior of the temporary storage tank 402 flows out through the spiral pipe 403, and the temperature inside the methanol synthesis reactor 100 is adjusted by the cooling water. S2. The cold water in the first water inlet pipe enters the interior of the temporary storage tank 402 and impacts the turbine fan blade 404. The turbine fan blade 404 rotates under the impact force. When the turbine fan blade 404 rotates, it drives the connecting shaft 501 to rotate coaxially. When the connecting shaft 501 rotates, it drives the stirring plate 503 to rotate through the rotating rod 502. The stirring plate 503 rotates while fitting against the inner wall of the catalyst box 107, and the catalyst is stirred when the stirring plate 503 rotates. S3. The output end of the control cylinder 608 moves downward in the vertical direction, and the output end presses on the top of the sliding rod 606. The sliding rod 606 slides on the inner wall of the cylinder 605. When the sliding rod 606 moves, it drives the leakage plate 603 to move downward in the vertical direction. The blocking block 604 provided at the bottom of the leakage plate 603 blocks the through holes provided on the surface of the distribution plate 602, and the flow rate of the mixed gas flow is controlled in real time.
