Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide supply, specifically relating to a continuous carbon dioxide supply device. Background Technology

[0002] Modern industry and agriculture are increasingly recognizing the importance of carbon dioxide. Carbon dioxide serves as a fundamental element for biological growth. Under suitable temperature and light conditions, it reacts with water to synthesize organic matter, which is then converted into nutrients needed by humans. Plants require carbon dioxide for growth; an atmospheric carbon dioxide concentration of 350-400 ppm is beneficial. Continuously injecting 5000-1000 ppm of carbon dioxide into the growing environment can improve quality, stabilize fruit ripening, and increase yield.

[0003] In the industrial sector, carbon dioxide is used as a welding shielding gas, a chemical raw material, and a refrigerant. Typically, carbon dioxide is produced primarily by burning liquefied petroleum gas (LPG) or natural gas. However, in recent years, the large-scale use of fossil fuels both domestically and internationally has exacerbated global warming. To meet the needs of conservation and safety, transforming the way carbon dioxide is generated is now imperative.

[0004] The existing carbon dioxide generator works by using combustion to produce carbon dioxide. The steel cylinders that hold liquefied petroleum gas are pressure vessels. Due to negligence and improper use, there are safety hazards, which can lead to many personal injury and safety accidents.

[0005] Therefore, a safe, continuous, and stable carbon dioxide supply device is urgently needed for development. Utility Model Content

[0072] This utility model provides an embodiment:

[0078] To ensure the reliability of ventilation, the passive ventilation assembly 2 includes: at least one ventilation component 201 and a filter screen 202; wherein, the ventilation component 201 is disposed on the first end plate 102; the ventilation component 201 can be a plate-shaped component and has eyebrow-shaped holes thereon to facilitate ventilation; the filter screen 202 is disposed on the ventilation component 201 and is used to filter the airflow passing through the eyebrow-shaped holes.

[0079] To ensure airtightness and carbon capture reliability, a sealing element 5 is provided between the working module 3 near the housing 1 and the inner wall of the housing 1 for sealing; the sealing element 5 can be a flexible pressure strip, such as a rubber pressure strip, to ensure good contact between the airflow and the medium.

[0080] In this embodiment, the working module 3 needs to perform both carbon capture and desorption. Therefore, the working module 3 in this embodiment, as... Figures 7-10 The assembly includes: a first workpiece 301, a second workpiece 302, and a third workpiece 303; wherein, the first workpiece 301 is detachably disposed inside the housing 1; the second workpiece 302 is disposed inside the first workpiece 301 and is detachably connected to the first workpiece 301, and the second workpiece 302 contains a medium for carbon capture; the third workpiece 303 is disposed between adjacent second workpieces 302 and is in contact with the second workpieces 302, for heating any of the second workpieces 302 to desorb the medium.

[0081] Furthermore, the first workpiece 301 includes: a frame 3011 and at least one recess 3012; the recess 3012 is disposed on the inner sidewall of the frame 3011; the recess 3012 is matched and connected to the second workpiece 302.

[0083] Furthermore, the third workpiece 303 includes: a heat-conducting part 3031 and a heating unit 3032; wherein, the heat-conducting part 3031 contacts the second workpiece 302 for heat transfer; the heating unit 3032 is disposed within the heat-conducting part 3031 for heating the medium within the second workpiece 302 for desorption. The heat-conducting part 3031 may be a finned structure or the like; the heating unit 3032 may be an electric heating unit; the medium may be solid amine.

[0084] Meanwhile, for a neat and aesthetically pleasing appearance, a power cord hole 101B is also provided on the housing body 101 for the power cords of the active ventilation unit 402 and the heating unit 3032 to pass through.

[0085] To facilitate control and use, this embodiment provides another embodiment.

[0086] like Figure 11The aforementioned continuous carbon dioxide supply device further includes a control component 6. Specifically, the control component 6 includes a control unit 601, a detection unit 602, and an instruction input unit 603. The detection unit 602 is disposed on the housing body of the housing 1 and electrically connected to the control unit 601, for collecting the carbon dioxide concentration within the housing body. The instruction input unit 603 interacts with the control unit 601 to collect user instructions. The control unit 601 manually controls the start / stop and rotation speed of the active ventilation component, and / or the start / stop and heating rate of the working module, according to the user instructions. The control unit 601 is electrically connected to the active ventilation component and sends a first system instruction based on the carbon dioxide concentration within the housing body to automatically control the rotation speed or start / stop of the active ventilation unit in the active ventilation component. The control unit 601 is electrically connected to the working module and sends a second system instruction based on the carbon dioxide concentration within the housing body to control the heating rate or start / stop of the third workpiece.

[0087] During operation, a carbon capture step is required first. At this time, the user inputs control commands via the command input unit 603, such as a keyboard or touchscreen. The control unit 601 sends a signal to control the active ventilation unit 402 in the active ventilation assembly 4 to reverse, allowing airflow into the housing 1. The medium then captures carbon dioxide from the air. After a preset time, once the medium is saturated, the user inputs control commands via the command input unit 603, such as a keyboard or touchscreen, to activate the third workpiece 303, which desorbs and removes the medium, creating a continuously increasing carbon dioxide accumulation environment within the housing 1. The control unit 601 continuously collects data from the detection unit 6. The carbon dioxide concentration data of 02; when the carbon dioxide concentration in the shell 1 reaches the first preset concentration, such as above 90%, the active ventilation unit 402 rotates forward to continuously discharge the carbon dioxide in the shell 1, forming a stable carbon dioxide supply to the outside, such as a high concentration of carbon dioxide of 5000~1000ppm; when the concentration at the detection port 101A is lower than the second preset threshold, such as 60%, the control unit 601 sends a signal, and the third workpiece 303 stops working and stops desorption; at the same time, the control unit 601 sends a signal to control the active ventilation unit 402 to reverse, so that the airflow enters the shell 1 and carbon is captured again by the medium, and so on, to complete the continuous supply of carbon dioxide.

[0088] During the above-mentioned operation, the system can enter manual control mode to control the system according to the instructions input by the user through the instruction input unit 603, such as controlling the opening, closing or turning of the active ventilation unit 402; or it can enter automatic control mode to automatically control the active ventilation unit 402 and the third workpiece 303 using the first preset threshold and the second preset threshold set in the control unit 601.

[0089] Furthermore, during the carbon dioxide output process, the rotation speed of the active ventilation unit 402 and the temperature change rate of the third workpiece 303 can be dynamically adjusted due to the change in carbon dioxide concentration inside the housing 1. For example, the carbon dioxide concentration data inside the housing 1 can be periodically detected, and the carbon dioxide concentration difference between two consecutive cycles can be obtained. If the concentration difference exceeds the set concentration difference threshold, it indicates that the carbon dioxide concentration is insufficient. At this time, the control unit 601 sends a control signal to increase the heating rate of the third workpiece 303, thereby increasing the heating temperature of the third workpiece 303, while reducing the rotation speed of the active ventilation unit 402 to increase the concentration of carbon dioxide output.

[0090] It should be clarified that the control unit 601 in this embodiment can be an external smart terminal, such as a mobile phone or PC, which connects to the carbon dioxide continuous supply device described in this embodiment via a data cable through any selectable data port to collect commands. Alternatively, it can be installed on the housing of the carbon dioxide continuous supply device described in this embodiment through an optional connection structure, such as a connector. In this case, the command input unit 603 can also be installed on the housing 1, such as a separate touch screen or keyboard, to collect commands from the control unit 601. The heat-conducting part 3031 in the third workpiece 303 can be a finned structure; the heating unit 3032 can be a heating wire.

[0091] The carbon dioxide continuous supply device of this utility model, due to the unique design of its working modules, allows the working airflow direction of the active ventilation unit 402 to be arbitrarily reversed. That is, by simply adjusting the direction of the active ventilation unit 402, the airflow of the passive ventilation component 2 can be set to outward, and the airflow of the active ventilation component can be set to inward, achieving free switching of airflow direction. Simultaneously, increasing or decreasing the number of working modules directly affects the discharged carbon dioxide concentration, thus increasing the adjustable range. Furthermore, by configuring a large-volume active ventilation unit 402, continuous output of carbon dioxide gas can be achieved. In practical use, the working modules can be made of PP plastic material, which is structurally stable and lightweight. During use, a detection unit, such as a carbon dioxide concentration sensor, can be installed at detection port 101A to collect the carbon dioxide concentration at detection port 101A in real time.

[0092] It needs to be clarified that: Figure 5 The air inlet and outlet are schematic diagrams showing the continuous discharge of carbon dioxide from the housing 1 when the active ventilation unit 402 rotates forward.

[0093] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions made by those skilled in the art within the technical scope disclosed in this utility model are all within the protection scope of this utility model. Therefore, the protection scope of this utility model is determined by the scope of the claims.
