Description

Technical Field

[0001] This utility model relates to the field of formic acid hydrogen production technology, specifically to a formic acid hydrogen production device. Background Technology

[0007] Furthermore, the liquid supply module includes a liquid storage tank connected to the pyrolysis reaction module and a liquid supply pump connected to the liquid storage tank.

[0008] Furthermore, the pyrolysis reaction module includes a pyrolysis reactor connected to the liquid supply module and a stirrer connected to the pyrolysis reactor and adapted to extend into the interior of the pyrolysis reactor, wherein a catalyst is provided inside the pyrolysis reactor.

[0009] Furthermore, a safety valve is installed on the pyrolysis reactor.

[0010] Furthermore, the gas processing module includes a liquid blocking device connected to the pyrolysis reaction module, a gas washing tank connected to the liquid blocking device, a water vapor separator connected to the gas washing tank, and a drying tank connected to the water vapor separator. The water vapor separator contains deionized water, and the drying tank is connected to the gas purification module.

[0011] Furthermore, the gas processing module also includes a heat exchanger connected between the liquid blocker and the drying tank, and a condensate storage tank connected to the gas washing tank. The condensate storage tank is also connected between the heat exchanger and the gas washing tank through a pipeline and is located below the heat exchanger.

[0012] Furthermore, the gas treatment module also includes a raw material adsorption tank connected between the water vapor separator and the drying tank, and the raw material adsorption tank is equipped with activated carbon.

[0013] Furthermore, the bottom of the condensate storage tank is connected to the water treatment module.

[0014] Furthermore, the gas purification module includes multiple tanks fixedly mounted in the cabinet, with the multiple tanks evenly arranged side by side on the fixed frame.

[0015] Furthermore, it also includes a control module located inside the cabinet. The liquid supply module, pyrolysis reaction module, gas processing module, and gas purification module are all electrically connected to the control module. The cabinet is provided with a cabinet door, and the cabinet door is provided with an operation panel that is electrically connected to the control module.

[0016] The technical solution of this utility model has the following advantages:

[0017] 1. The formic acid hydrogen production device provided by this utility model includes a catalyst placed in the cracking reaction module. The catalyst reacts with the hydrogen production feedstock to produce high-temperature hydrogen-rich gas. A gas treatment module dries and removes impurities from the gas produced in the cracking reaction module, thus obtaining high-purity hydrogen-rich gas. A gas purification module further purifies the dried and purified gas from the gas treatment module, thus obtaining high-purity hydrogen. A water treatment module treats and discharges the liquid separated by cooling and condensation in the gas treatment module, ensuring that the discharged liquid is environmentally friendly and safe, and preventing environmental pollution.

[0018] 2. The formic acid hydrogen production apparatus provided by this utility model includes a liquid supply module comprising a storage tank connected to the cracking reaction module and a liquid supply pump connected to the storage tank. This configuration allows the liquid supply module to continuously supply formic acid feedstock to the cracking reaction module via the liquid supply pump, ensuring uninterrupted feedstock supply during hydrogen production.

[0019] 3. The formic acid hydrogen production apparatus provided by this utility model includes a cracking reaction module comprising a cracking reactor connected to a liquid supply module and a stirrer connected to the cracking reactor and adapted to extend into the cracking reactor. A catalyst is provided inside the cracking reactor. With this configuration, after the formic acid feedstock enters the cracking reactor, the continuous stirring of the stirrer ensures sufficient contact between the formic acid feedstock and the catalyst inside the cracking reactor for a catalytic reaction, guaranteeing catalytic reaction efficiency and improving hydrogen production efficiency.

[0020] 4. The formic acid hydrogen production apparatus provided by this utility model has a safety valve installed on the cracking reactor. This design can avoid the risk of overpressure in the cracking reactor.

[0021] 5. The formic acid hydrogen production apparatus provided by this utility model includes a gas processing module comprising a liquid blocking device connected to a cracking reaction module, a gas washing tank connected to the liquid blocking device, a water vapor separator connected to the gas washing tank, and a drying tank connected to the water vapor separator. The water vapor separator contains deionized water, and the drying tank is connected to a gas purification module. This configuration allows the liquid blocking device to block the catalyst, formic acid, and some water vapor carried in the hydrogen-rich gas obtained after the catalytic reaction. The deionized water in the gas washing tank further filters out the formic acid in the hydrogen-rich gas delivered from the liquid blocking device. The water vapor separator separates the water vapor from the hydrogen-rich gas, reducing its water content. The drying tank further dries the low-water-content hydrogen-rich gas, resulting in impurity-free hydrogen-rich gas suitable for purification. This purified hydrogen-rich gas is then transported to the gas purification module for further purification to obtain hydrogen.

[0022] 6. The formic acid hydrogen production device provided by this utility model includes a gas processing module further comprising a heat exchanger connected between the liquid blocking device and the drying tank, and a condensate storage tank connected to the gas washing tank. The condensate storage tank is also connected between the heat exchanger and the gas washing tank via a pipeline and is located below the heat exchanger. With this configuration, since the hydrogen-rich gas produced after the reaction of formic acid and the catalyst is a high-temperature gas, the temperature of the hydrogen-rich gas entering the heat exchanger can be reduced through the heat exchanger. Simultaneously, heat exchange occurs through the heat exchanger, and while cooling the high-temperature hydrogen-rich gas, the heat energy generated during cooling can be returned to the liquid supply module, thereby preheating the formic acid in the liquid storage tank. No additional preheating equipment is required, effectively reducing energy consumption and thus reducing the cabinet volume and size, thereby reducing the overall footprint of the formic acid hydrogen production device. When the hydrogen-rich gas is cooled, condensate is generated, which can be directly stored in the condensate storage tank located below the heat exchanger.

[0023] 7. The formic acid hydrogen production apparatus provided by this utility model further includes a raw material adsorption tank connected between a water vapor separator and a drying tank in its gas treatment module. The raw material adsorption tank is equipped with activated carbon. With this configuration, the low-moisture, hydrogen-rich gas after separation by the water vapor separator enters the raw material adsorption tank for further filtration and impurity removal, further improving the purity of the hydrogen-rich gas. The gas is then transported from the raw material adsorption tank to the drying tank for drying.

[0024] 8. The formic acid hydrogen production device provided by this utility model has a condensate storage tank bottom connected to a water treatment module. The water treatment module is suitable for adsorbing formic acid in the condensate in the condensate storage tank, thereby ensuring the safety and environmental protection of the discharged liquid.

[0034] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figures 1-3 The formic acid hydrogen production apparatus shown includes a cabinet and a liquid supply module 100, a cracking reaction module 200, a gas processing module 300, and a gas purification module 400 arranged in sequence within the cabinet. It also includes a water treatment module arranged within the cabinet and connected to the gas processing module 300. The liquid supply module 100 is adapted to provide hydrogen production feedstock to the cracking reaction module 200. The cracking reaction module 200 contains a catalyst adapted to catalytically react with the hydrogen production feedstock. The gas processing module 300 is adapted to cool, dry, and remove impurities from the gas produced by the catalytic reaction in the cracking reaction module 200. The gas purification module 400 is adapted to purify the gas after drying and impurity removal in the gas processing module 300. The water treatment module is adapted to process and discharge the liquid condensed and separated in the gas processing module 300.

[0036] This formic acid hydrogen production device places a catalyst in the cracking reaction module 200, and the catalyst reacts with the hydrogen production feedstock to produce high-temperature hydrogen-rich gas. The gas produced by the catalytic reaction in the cracking reaction module 200 is dried and impurities are removed by the gas processing module 300 to obtain high-purity hydrogen-rich gas. The gas purified by the gas processing module 400 is further purified to obtain high-purity hydrogen. The liquid produced after drying in the gas processing module 300 is treated and discharged by the water treatment module, which ensures that the liquid discharged after hydrogen production is environmentally friendly and safe, and avoids environmental pollution.

[0037] In this embodiment, the liquid supply module 100 includes a storage tank 110 connected to the cracking reaction module 200 and a liquid supply pump 120 connected to the storage tank 110. This configuration allows the liquid supply module 100 to continuously supply formic acid feedstock to the cracking reaction module 200 via the liquid supply pump 120, ensuring uninterrupted feedstock supply during hydrogen production.

[0038] In this embodiment, the cracking reaction module 200 includes a cracking reactor 210 connected to the liquid supply module 100 and a stirrer 220 connected to the cracking reactor 210 and adapted to extend into the cracking reactor 210. A catalyst is disposed inside the cracking reactor 210. With this configuration, after the formic acid feedstock enters the cracking reactor 210, the continuous stirring of the stirrer 220 ensures sufficient contact between the formic acid feedstock and the catalyst inside the cracking reactor 210 for a catalytic reaction, guaranteeing catalytic reaction efficiency and improving hydrogen production efficiency.

[0039] Specifically, the stirrer 220 is a magnetically coupled stirrer 220, and the stirrer 220 is placed in the middle of the cracking reactor 210, which can effectively stir and mix formic acid and catalyst, while achieving zero leakage of the stirrer 220.

[0040] Specifically, the cracking reactor 210 is equipped with a liquid-phase catalyst inside and an oil bath heating layer outside. The oil bath heating method has high heating efficiency and can achieve constant temperature heating control.

[0041] Specifically, a one-way valve is installed between the storage tank and the pyrolysis reactor 210. This design prevents the internal pressure of the pyrolysis reactor 210 from backflowing to the outside along the formic acid pipeline.

[0042] Specifically, a safety valve 230 is installed on the pyrolysis reactor 210. This design helps to prevent the pyrolysis reactor 210 from experiencing overpressure.

[0043] In this embodiment, the gas processing module 300 includes a liquid blocking device 310 connected to the pyrolysis reaction module 200, a gas washing tank 340 connected to the liquid blocking device 310, a water vapor separator 350 connected to the gas washing tank 340, and a drying tank 370 connected to the water vapor separator 350. The water vapor separator 350 contains deionized water, and the drying tank 370 is connected to the gas purification module 400. This configuration allows the liquid barrier 310 to block the catalyst, formic acid, and some water vapor carried in the hydrogen-rich gas obtained after the catalytic reaction. The deionized water in the gas scrubber 340 further filters out the formic acid in the hydrogen-rich gas delivered from the liquid barrier 310, preventing formic acid corrosion of downstream equipment. The water vapor separator 350 separates water vapor from the hydrogen-rich gas, reducing its water content, dew point, and improving the efficiency of downstream equipment. The drying tank 370 further dries the low-water-content hydrogen-rich gas, resulting in impurity-free hydrogen-rich gas suitable for purification. This purified hydrogen-rich gas is then transported to the gas purification module 400 for further purification to obtain hydrogen. Specifically, three drying tanks 370 are arranged side-by-side.

[0044] Specifically, the liquid blocker 310 is also provided with a return port that is connected to the cracking reactor 210. The catalyst and formic acid in the hydrogen-rich gas blocked by the liquid blocker 310 can be returned to the cracking reactor 210 through the return port. This setting can reduce the loss of catalyst and formic acid.

[0045] In this embodiment, the gas processing module 300 also includes a heat exchanger 320 connected between the liquid blocker 310 and the drying tank 370. With this configuration, since the hydrogen-rich gas produced after the reaction of formic acid with the catalyst is a high-temperature gas, the temperature of the hydrogen-rich gas entering the heat exchanger 320 can be reduced. Simultaneously, heat exchange through the heat exchanger 320 cools the high-temperature hydrogen-rich gas, and the heat energy generated during this cooling process can be returned to the liquid supply module 100, thereby preheating the formic acid in the storage tank 110. This allows for a continuous and stable supply of preheated formic acid to the cracking reactor 210 with low energy consumption, eliminating the need for additional preheating equipment. No preheating step is required before the formic acid enters the cracking reaction module 200, improving hydrogen production efficiency, effectively reducing energy consumption, and consequently reducing the cabinet volume and size, thus reducing the overall footprint of the formic acid hydrogen production unit.

[0046] In this embodiment, the gas processing module 300 further includes a condensate storage tank 330 connected to the gas scrubbing tank 340. The condensate storage tank 330 is also connected between the heat exchanger 320 and the gas scrubbing tank 340 via a pipeline and is located below the heat exchanger 320. When the hydrogen-rich gas is cooled, condensate is generated, and the condensate can directly enter the condensate storage tank 330 located below the heat exchanger 320 for temporary storage.

[0047] In this embodiment, the gas processing module 300 further includes a raw material adsorption tank 360 connected between the water vapor separator 350 and the drying tank 370, and activated carbon is provided inside the raw material adsorption tank 360. With this configuration, the low-moisture, hydrogen-rich gas after separation by the water vapor separator 350 enters the raw material adsorption tank 360 for further filtration and impurity removal, further improving the purity of the hydrogen-rich gas, and is then transported from the raw material adsorption tank 360 to the drying tank 370 for drying.

[0048] Specifically, the bottom of the condensate storage tank 330 is connected to the water treatment module. The water treatment module is suitable for adsorbing formic acid in the condensate inside the condensate storage tank 330, thereby ensuring the safety and environmental protection of the discharged liquid.

[0049] In this embodiment, the gas purification module 400 includes multiple tanks 410 mounted in a cabinet via a mounting frame 420. The tanks 410 are evenly arranged side-by-side on the mounting frame 420. This arrangement allows for external assembly and subsequent hoisting of the entire unit into the cabinet. The formic acid hydrogen production device achieves component standardization, modular production, and convenient and efficient installation. Specifically, the gas purification module 400 uses a PSA (Pressure Swing Adsorption) system to purify hydrogen-rich gas to obtain high-purity hydrogen.

[0050] In this embodiment, a control module is also included in the cabinet. The liquid supply module 100, the pyrolysis reaction module 200, the gas treatment module 300, the gas purification module 400, the gas reaction module, and the water treatment module are all electrically connected to the control module. By controlling the operation of multiple modules through the control system, the safe and stable operation of the formic acid hydrogen production system can be ensured.

[0051] The cabinet is equipped with a door, and an operation panel electrically connected to the control module is installed on the door. Specifically, a cooling exhaust fan is installed at the top of the cabinet.

[0052] In this embodiment, the liquid supply module 100 is located behind the pyrolysis reaction module 200, the gas purification module 400 is located on the left side of the cabinet, and the water treatment module is located on the right side of the pyrolysis reaction module 200 and below the gas treatment module 300.

[0053] In this embodiment, the gas processing module 300 is fixed inside the cabinet by a crossbeam, and its components are arranged in two layers. Specifically, the lower layer, from left to right, consists of a liquid blocker 310, a condensate storage tank 330, a gas scrubbing tank 340, and a water vapor separator 350. The upper layer, from left to right, consists of a heat exchanger 320, three drying tanks 370, and a raw material adsorption tank 360. This arrangement allows for a more compact internal structure within the cabinet, reducing the space occupied and thus decreasing the cabinet's size and floor space. Specifically, the leftmost drying tank 370 is connected to the gas purification module 400, and the rightmost drying tank 370 is connected to the raw material adsorption tank 360.

[0054] Specifically, the liquid blocker 310, condensate storage tank 330, gas washing tank 340, raw material adsorption tank 360, and drying tank 370 all adopt the same tank size 410. All components adopt an external mounting method, which can be assembled outside the cabinet and then installed into the cabinet as a whole, reducing installation time and improving assembly efficiency.

[0055] In this embodiment, pressure sensors are installed inside the liquid supply module 100, the reaction pyrolyzer, the gas processing module 300, and the gas purification module 400. A hydrogen alarm is installed inside the cabinet, and a warning light is installed on the top of the cabinet. The pressure sensors and hydrogen alarm are connected to the control module, which automatically handles any abnormalities that occur in the equipment to avoid overpressure or large-scale hydrogen leakage, thus ensuring the safe and reliable operation of the equipment.

[0056] like Figure 4 As shown in the figure, this embodiment provides a system flow diagram of a formic acid hydrogen production device. Formic acid is transported from the liquid supply module 100 to the cracking reaction module 200, where it decomposes under the action of a catalyst to produce high-temperature hydrogen-rich gas. The high-temperature hydrogen-rich gas is cooled and impurities and moisture are removed by the gas treatment module 300, and then high-purity hydrogen is obtained by the gas purification module 400. The condensate containing trace amounts of formic acid generated during the gas treatment process is discharged from the system after being treated by the water treatment module 500.

[0057] In summary, this formic acid hydrogen production device incorporates a catalyst within the cracking reaction module 200. The catalyst reacts with the hydrogen production feedstock to produce high-temperature hydrogen-rich gas. The gas processing module 300 cools, dries, and removes impurities from the catalytic reaction in the cracking reaction module 200, resulting in high-purity hydrogen-rich gas at a suitable temperature. The gas purification module 400 further purifies the dried and impurity-removed gas from the gas processing module 300, producing high-purity hydrogen. Finally, the water treatment module treats and discharges the liquid separated by cooling and condensation in the gas processing module 300, ensuring the environmental safety of the discharged liquid and preventing pollution. The multi-stage formic acid filtration and adsorption units effectively remove formic acid from the gas, while the multi-stage moisture separation and adsorption units effectively remove moisture, ensuring both purification efficiency and safe, long-term operation of the gas purification device.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
