[0022] Figure 1 This is a schematic diagram of the connection structure of each module of this utility model. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figure 1 A carbon dioxide capture device with separation function according to an embodiment of the present invention includes a capture module 1, a separation module 2, a storage module 3, an automatic control module 4, and a cleaning and maintenance module 5.

[0025] The capture module 1 is located at the front end of the device and is connected to the outside air through an airflow control valve. The captured gas enters the separation module 2 through a connecting pipe. After separation, the separated carbon dioxide enters the storage module 3 through a high-pressure pipe. The automatic control module 4 is connected to the capture module 1, separation module 2 and storage module 3 through cables and is responsible for adjusting the operating parameters of each module. The cleaning and maintenance module 5 is connected to the capture module 1, separation module 2 and automatic control module 4 through pipes and data cables and is responsible for cleaning the device and monitoring its operating status.

[0026] The collection module 1 includes an adsorption unit and a pretreatment unit. The pretreatment unit is located at the front end of the adsorption unit and is connected to the adsorption unit through a pipe to ensure that the pretreated air can be evenly distributed in the adsorption unit.

[0027] The adsorption unit is equipped with a high-efficiency adsorption material inside, and the outer wall of the adsorption unit adopts a honeycomb structure to increase the surface area, ensuring that carbon dioxide molecules in the air can be quickly captured. The adsorption unit is connected to the outside air through an airflow control valve, which is used to regulate the airflow rate so that the adsorption unit can work efficiently under different air concentrations. The adsorption material is a porous material with high selectivity and high adsorption capacity, which can adsorb a large amount of carbon dioxide in a short time.

[0028] The pretreatment unit includes a primary filter and a humidity regulator. The primary filter is used to remove particulate matter and impurities from the air, and the humidity regulator is used to regulate the humidity of the air entering the adsorption unit to prevent the adsorption material from becoming damp and failing.

[0029] Before entering the adsorption unit, the air first passes through the primary filter of the pretreatment unit. The primary filter removes large particles and impurities from the air to prevent them from affecting the adsorption material's performance after entering the adsorption unit. Subsequently, the air humidity is regulated by a humidity controller to ensure that the humidity of the air entering the adsorption unit is within an appropriate range, preventing the adsorption material from reducing its adsorption capacity due to moisture. The air treated by the pretreatment unit is evenly distributed into the adsorption unit to ensure that the adsorption material in the adsorption unit can fully perform its function of capturing carbon dioxide.

[0030] Separation module 2 includes a membrane filtration unit and a pressure regulating unit. The membrane filtration unit has a multi-layer composite membrane inside. The multi-layer composite membrane adopts a nanopore design, which can efficiently separate carbon dioxide and other gases. The pore size distribution of the multi-layer composite membrane is optimized to ensure that carbon dioxide can pass through preferentially while other gases are blocked. The membrane filtration unit is connected to the collection module 1 through a connecting pipe. When gas enters the membrane filtration unit, carbon dioxide molecules can pass through the composite membrane preferentially due to their smaller molecular size, while larger gas molecules such as nitrogen and oxygen are blocked outside the membrane. Through this selective filtration, the membrane filtration unit can achieve fine separation of carbon dioxide.

[0031] The pressure regulating unit 22 is located at the front end of the membrane filtration unit. It controls the gas pressure entering the membrane filtration unit through a pressure sensor and a regulating valve to ensure that the gas passes through the composite membrane at the optimal pressure, thereby improving the separation efficiency. The pressure regulating unit is directly connected to the membrane filtration unit and uses a pressure sensor to monitor and regulate the pressure in real time. The pressure sensor can detect any pressure fluctuations and immediately send a signal to the regulating valve for corresponding adjustments to ensure that the gas pressure is kept within the set range. This avoids membrane damage due to excessive pressure or separation effect due to excessively low pressure. Through this real-time regulation, the pressure regulating unit ensures that the membrane filtration unit performs carbon dioxide separation under optimal operating conditions.

[0032] Storage module 3 includes a compression unit and a storage container unit. The compression unit is equipped with a high-efficiency compressor to compress the separated pure carbon dioxide, reducing its volume for easy storage. The compression unit adopts a multi-stage compression design to gradually reduce the gas volume and improve compression efficiency. The compression unit is connected to the separation module 2 through a pipeline to ensure that the separated carbon dioxide directly enters the compression unit for processing.

[0033] The storage container unit employs high-pressure storage technology to ensure the safe storage of carbon dioxide under high-pressure conditions. The storage container is equipped with a safety valve and a pressure monitoring system to monitor the storage pressure in real time and automatically release pressure in case of overpressure. The storage container unit is connected to the compression unit through a high-pressure pipeline to ensure the safe storage of compressed carbon dioxide. The safety valve and pressure monitoring system of the storage container monitor the pressure level inside the container in real time. When the pressure exceeds the safety threshold, the safety valve will automatically open to release some gas to prevent the container from overpressure explosion. The pressure monitoring system can continuously record and display the pressure data inside the container to ensure the safety and reliability of the storage process.

[0034] The automatic control module 4 includes a sensor unit and a control unit. The sensor unit includes a temperature sensor, a pressure sensor, and a gas concentration sensor, which are distributed inside the collection module 1, the separation module 2, and the storage module 3. They are used to monitor the operating status of each module in real time. In specific implementation, by distributing the temperature sensor, pressure sensor, and gas concentration sensor in the collection module 1, the separation module 2, and the storage module 3, the temperature, pressure, and gas concentration of these modules are monitored in real time. The sensors transmit the collected data to the control unit through data lines. The control unit processes and analyzes the data in real time. Each sensor is precisely calibrated to ensure the accuracy and reliability of the data and provide reliable monitoring of the operating status.

[0035] The control unit incorporates advanced control algorithms and a processor, enabling it to automatically adjust the operating parameters of each module based on data from the sensor units. This includes adjusting the airflow of the capture module, the pressure of the separation module, and the compression ratio of the storage module, ensuring efficient operation of the device under various conditions. The control unit is connected to each unit via cables and can receive and send control commands in real time, ensuring normal operation of the device under different working conditions. The processor in the control unit adopts a low-power design to ensure stability during long-term operation and avoid malfunctions caused by processor overheating or excessive power consumption.

[0036] The cleaning and maintenance module 5 includes an automatic cleaning unit and a diagnostic unit. The automatic cleaning unit includes a spray device and a cleaning fluid storage tank, which is used to clean the adsorption unit and the membrane filtration unit regularly to prevent clogging of the adsorption material and the filter membrane. The automatic cleaning unit is connected to the adsorption unit and the membrane filtration unit through pipelines. The unit sprays cleaning fluid onto the adsorption unit and the membrane filtration unit regularly through the spray device and the cleaning fluid storage tank. The cleaning fluid is evenly distributed on the surface of the adsorption material and the filter membrane through pipelines, effectively removing accumulated impurities and particulate matter, preventing clogging of the material and the membrane, and ensuring the normal operation of the equipment. The spraying time and frequency of the cleaning fluid are adjusted by the control unit in the automatic control module 4 according to the actual situation.

[0037] The diagnostic unit has a built-in fault detection algorithm that can diagnose the equipment's operating status in real time and alert maintenance personnel through an alarm system when an anomaly is detected. The diagnostic unit connects to the sensor and control units via data cables, enabling it to acquire and analyze operating data from each module. The alarm system includes audible and visual alarms and remote notification functions. Through its built-in fault detection algorithm, it monitors the operating status of each module in real time. When the diagnostic unit detects an anomaly, it immediately alerts maintenance personnel via audible and visual alarms and the remote notification system, indicating that the equipment has a fault and requires repair. The diagnostic unit connects to the sensor and control units via data cables to acquire, analyze, and process data such as temperature, pressure, and gas concentration from each module in real time, ensuring the safe and stable operation of the equipment.

[0038] Working principle: First, outside air enters through the airflow control valve of the capture module 1, where the high-efficiency adsorption material quickly captures carbon dioxide from the air. After filtration and humidity adjustment by the pretreatment unit, the gas enters the separation module 2, where a multi-layer composite membrane and pressure regulation unit separate the carbon dioxide from other gases. The separated carbon dioxide enters the storage module 3 through a high-pressure pipeline, where a high-efficiency compressor performs multi-stage compression and stores it in a high-pressure resistant stainless steel container equipped with a safety valve and pressure monitoring system. The automatic control module 4 monitors the operating status of each module in real time through sensors and automatically adjusts parameters based on the data. The cleaning and maintenance module 5 regularly cleans the adsorption unit and membrane filtration unit and monitors the equipment status in real time to ensure efficient and stable operation of the device.
