Description

Technical Field

[0001] This invention relates to the field of carbon dioxide treatment technology, and more specifically to a photocatalytic reaction vessel for converting carbon dioxide into formic acid. Background Technology

[0002] The rising concentration of carbon dioxide in the atmosphere is exacerbating the global greenhouse effect and posing a serious threat to the ecological environment. Therefore, the fixation, activation, and chemical conversion of carbon dioxide into organic matter are of significant practical importance to the future of humankind. Due to the high stability and inertness of carbon dioxide, it is difficult to activate and its conversion requires energy. Current research on carbon dioxide conversion pathways mainly includes electrochemical conversion, bioconversion, and photocatalytic conversion.

[0003] Carbon dioxide can be converted into formic acid through photocatalytic conversion, but currently available photocatalytic conversion devices for carbon dioxide have many problems: 1. The utilization efficiency of sunlight is low, with most devices relying solely on natural light and failing to achieve multi-level utilization and storage of light energy; 2. Uneven distribution of reactants leads to insufficient contact between the catalyst and reactants, thus limiting conversion efficiency; 3. In conditions of insufficient light or at night, the lack of continuous and stable auxiliary energy support affects the ability to operate continuously.

[0004] Therefore, in view of the shortcomings of the prior art, it is necessary to provide a reaction vessel for the photocatalytic conversion of carbon dioxide into formic acid. Summary of the Invention

[0005] The main objective of this invention is to provide a photocatalytic reaction vessel for converting carbon dioxide into formic acid, in order to solve the problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A photocatalytic carbon dioxide to formic acid conversion reactor includes a main body, a filter at the top of the main body, a movable photovoltaic power generation and energy storage component on the periphery of the top of the main body, a reciprocating spraying component inside the main body, a raw material mixing component connected to the reciprocating spraying component, several sets of photocatalyst beds at the lower end of the reciprocating spraying component inside the main body, and a discharge port at the bottom of the main body.

[0007] Furthermore, the active photovoltaic power generation and energy storage component includes a photovoltaic panel, a first hinge seat is provided at the top of the main body, a second hinge seat is provided on the side wall of the main body, the photovoltaic panel is hinged to the first hinge seat, a third hinge seat is provided on the side wall of the photovoltaic panel, the second hinge seat and the third hinge seat are connected by an electric telescopic rod, and a battery is connected to the photovoltaic panel. The battery is used to supply power to other electrical components of the reactor.

[0008] Furthermore, the reciprocating spraying assembly includes a drive motor, a drive screw, and a slide rod. The drive screw is rotatably connected to the inside of the main body, the drive motor is fixedly connected to the main body, and the drive screw is drively connected to the drive motor. The slide rod is fixedly connected to the inside of the main body, and a slide seat is threaded onto the drive screw. The slide seat is slidably connected to the slide rod, and an atomizing nozzle is provided on the slide seat. The atomizing nozzle is connected to the raw material mixing assembly via a hose.

[0009] Furthermore, the raw material mixing assembly includes a mixing chamber, inside which are a stirring fan roller and a suction pump. The mixing chamber is provided with a carbon dioxide inlet and a water inlet, and the suction pump is connected to the atomizing nozzle via a hose.

[0010] Furthermore, the photocatalyst bed is provided in three sets, and the three sets of photocatalyst beds are evenly distributed on the lower side of the reciprocating spray assembly.

[0011] Furthermore, the interior of the main body is provided with several exposure lamps, which are used to provide light of a specific wavelength.

[0012] Furthermore, a heating rod is provided inside the main body, and the heating rod is electrically connected to the active photovoltaic power generation and energy storage component.

[0013] Furthermore, the bottom of the main body is provided with support legs.

[0014] Furthermore, it also includes a PLC, which is used for the operation control of the reactor.

[0015] Furthermore, an exhaust gas collection port is provided on the top of the main body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Achieving efficient cascade utilization of sunlight: Specific wavelengths of light are filtered and used directly for photocatalytic reactions. At the same time, active photovoltaic power generation and energy storage components are used to convert excess light energy into electrical energy and store it to supply electrical devices within the system, significantly improving the overall utilization rate of light energy.

[0017] To improve the uniformity of reactant distribution: the reciprocating spray assembly and atomizing nozzle are used together to allow the atomized material after the carbon dioxide and water mixture to be sprayed evenly in the horizontal direction onto the multi-layer photocatalyst bed, thereby enhancing the contact between the raw materials and the photocatalyst bed and improving the catalytic reaction efficiency.

[0018] System integration and self-sufficiency design: The active photovoltaic power generation and energy storage components can automatically adjust their angle according to the sun's position to maintain optimal power generation; the generated energy is used to drive equipment such as motors, exposure lamps, and heating rods, achieving energy self-sufficiency and intelligent control, reducing dependence on external energy.

[0019] Enhanced controllability of reaction conditions: The built-in exposure lamp can supplement specific wavelength light sources to ensure stable light conditions; the heating rod can adjust the reaction temperature, further optimize the catalytic environment, and improve the formic acid formation rate.

[0020] Highly adaptable and supports continuous operation: When there is insufficient light, the system can be powered by a battery to maintain operation, ensuring the continuous progress of the reaction process and broadening the application range of the device in real environments.
