An lower tower body air outlet pipe 6 is provided on the lower side wall of the transition duct 4. Adsorption devices 7 are provided inside the upper tower body 1 and the lower tower body 2; An upper tower body contaminated nitrogen inlet pipe 8 is provided on the top of the upper tower body 1, and the lower end of the upper tower body contaminated nitrogen inlet pipe 8 extends into the upper tower body 1; A lower supporting layer 9 is provided at the bottom of the lower tower body 2, and a lower tower body air inlet pipe 10 is provided in the lower supporting layer 9.

The molecular sieve adsorbent is evenly filled in the preset frame structure inside the upper tower body 1 and the lower tower body 2. During the filling process, a vibration device is used to fill the adsorbent tightly, reduce the gaps between the particles, and ensure the adsorption effect. At the same time, after the filling is completed, the surface of the adsorption device is smoothed to ensure that the gas can pass through the adsorption device evenly. The upper tower body 1 and the lower tower body 2 are connected by an intermediate support layer 3. The intermediate support layer 3 is provided with a transition pipe 4 and corresponding inlet and outlet pipes. The structure is compact and reasonable. This design makes the overall layout of the equipment clear, the functions of each part clear, and it is easy to install, maintain and overhaul.

The internal adsorption device 7 is a molecular sieve adsorbent filling layer, which can effectively adsorb impurities in the gas. The guide hole at the top of the intermediate support layer 3 helps to distribute the gas between the upper and lower tower bodies. The above structure realizes dual use of one tower, so that the upper tower body 1 and the lower tower body 2 are alternately in the adsorption and analysis state, which improves the utilization rate of the equipment, reduces the equipment floor space and investment cost, and is suitable for places with requirements on space and cost.

[0021] See also Figure 1 , the adsorption device 7 is a molecular sieve adsorbent filling layer; An internal welded plugging plate 11 is provided in the transition duct 4, which divides the interior of the transition duct 4 into an upper flow channel and a lower flow channel. The upper flow channel is connected to the upper tower body contaminated nitrogen outlet pipe 5, and the lower flow channel is connected to the lower tower body air outlet pipe 6; Select molecular sieve adsorbents with appropriate pore size and particle size, such as 5A or 13X molecular sieves, and evenly fill them in the preset frame structure inside the upper tower body 1 and the lower tower body 2. The filling density is determined according to the actual adsorption requirements to ensure good adsorption effect and gas permeability. For the internal welding plugging plate 11, it is welded with steel plates of the same material as the transition pipe 4 to ensure welding sealing, prevent gas leakage, and ensure that the upper flow channel and the lower flow channel are completely isolated; The adsorption device 7 is a molecular sieve adsorbent filling layer: the molecular sieve adsorbent filling layer is selected as the adsorption device 7, which can effectively adsorb impurities and moisture in the gas and improve the gas purity. Its uniform filling and appropriate pore size design ensure sufficient contact and efficient adsorption when the gas passes through. At the same time, it is easy to replace and maintain, and improves the stability and reliability of the equipment operation. An internal welded plugging plate 11 is provided in the transition pipe 4: an internal welded plugging plate 11 is provided in the transition pipe 4, which divides the interior of the pipe into an upper flow channel and a lower flow channel, thereby realizing a clear division of the gas flow path. The upper flow channel is connected to the upper tower body contaminated nitrogen outlet pipe 5, and the lower flow channel is connected to the lower tower body air outlet pipe 6. This design ensures that the gas flows do not interfere with each other when the upper tower body and the lower tower body switch between adsorption and decomposition states, thereby ensuring the efficient operation of the equipment with dual use of one tower and improving the gas treatment efficiency and equipment utilization rate.

[0022] A tower-type dual-function molecular sieve adsorber system, based on the above-mentioned tower-type dual-function molecular sieve adsorber, please refer to Figure 1 、 Figure 2 and Figure 3 ,include: Tower-type dual-function molecular sieve adsorber 12, monitoring module 13, valve group 14, data acquisition module 15 and human-computer interaction module 16; The monitoring module 13 includes a sensor group 17 and a controller 18. The sensor group 17 is respectively installed on the pipelines of the upper tower body dirty nitrogen inlet pipe 8, the upper tower body dirty nitrogen outlet pipe 5, the lower tower body air inlet pipe 10 and the lower tower body air outlet pipe 6; The valve group 14 includes a plurality of switching valves 19, which are respectively installed on the pipelines of the upper tower body dirty nitrogen inlet pipe 8, the upper tower body dirty nitrogen outlet pipe 5, the lower tower body air inlet pipe 8, and the lower tower body air outlet pipe 6; The sensor group 17 is electrically connected to the data acquisition module 15, the data acquisition module 15 is electrically connected to the controller 18, and the controller 18 is electrically connected to the valve group 14 and the human-computer interaction module 16 respectively; The sensor group 17 is used to collect gas parameters in the pipeline. The data acquisition module 15 is used to receive and store the data collected by the sensor group 17. The controller 18 is used to receive the data transmitted by the data acquisition module 15 and control the switch state of the valve group 14. The human-computer interaction module 16 is used to display data and receive operation instructions. The control logic 23 can be set to determine whether the adsorption or desorption state of the current tower body reaches a preset threshold value based on the gas pressure, temperature and flow data collected in real time by the sensor group 17 through a preset algorithm. If so, the switching instruction of the valve group 14 is triggered to realize the automatic alternating adsorption and desorption of the upper tower body 1 and the lower tower body 2, thereby ensuring continuous and efficient operation of the system; Tower-type dual-function molecular sieve adsorber system: This system integrates a tower-type dual-function molecular sieve adsorber 12, a monitoring module 13, a valve group 14, a data acquisition module 15 and a human-computer interaction module 16 to form a closed-loop control system. The gas parameters in the pipeline are collected in real time through the sensor group 17. The data acquisition module 15 is responsible for receiving and storing data. The controller 18 automatically controls the opening and closing of the valve group 14 according to the data to realize alternating adsorption and desorption of the upper and lower tower bodies. This design not only improves the automation level of the system, but also ensures the continuity and stability of the adsorption process. At the same time, the introduction of the human-computer interaction module 16 enables the operator to monitor the system status in real time and receive operating instructions, thereby improving the operability and maintenance efficiency of the system.

[0023] See also Figure 1 、 Figure 2 and Figure 3 The sensor group 17 includes a pressure sensor 20, a temperature sensor 21 and a flow sensor 22. The pressure sensor 20 is used to collect the gas pressure in the pipeline, the temperature sensor 21 is used to collect the gas temperature in the pipeline, and the flow sensor 22 is used to collect the gas flow in the pipeline; Regarding the installation of the sensor group 17, it can be further clarified that its installation method is to use a threaded connection or a flange connection to fix it on the pipeline to ensure a tight connection and easy disassembly and maintenance. At the same time, in order to ensure the accuracy of the collected data, the pressure sensor 20, the temperature sensor 21 and the flow sensor 22 need to be calibrated before installation. The calibration can be carried out by a professional metrology institution in accordance with relevant standards to ensure that the measurement error is within the specified range. The pressure sensor 20 collects the gas pressure in the pipeline, which can timely grasp the system pressure changes and prevent abnormal pressure from causing damage to the equipment; the temperature sensor 21 collects the gas temperature, which helps to monitor whether the system temperature is within the appropriate range and avoid the adsorption effect affected by too high or too low temperature; the flow sensor 22 collects the gas flow, which can accurately understand the gas transportation situation and ensure the stable operation of the system. These sensors work together to provide comprehensive and accurate data to the controller 18, so that the controller 18 can accurately control the switching state of the valve group 14, and realize that the upper tower body 1 and the lower tower body 2 are alternately in the adsorption state and the decomposition state, thereby improving the working efficiency and reliability of the tower-type dual-function molecular sieve adsorber.

[0024] See also Figure 1 、 Figure 2 and Figure 3 The controller 18 has a built-in control logic 23, which automatically controls the switching of the valve group according to the data collected by the sensor group 17 or the preset time, so that the upper tower body 1 and the lower tower body 2 are alternately in the adsorption state and the desorption state; The control logic 23 built into the controller 18 can be implemented by programming in a programming language (such as C, Python, etc.) according to actual needs. The program first sets a reasonable range threshold and a preset time parameter for the data collected by the sensor group 17. During operation, the gas parameters collected by the sensor group 17 are continuously read. When the parameter exceeds the threshold or reaches the preset time, an electrical signal is sent to the solenoid valve to control the opening and closing of the switching valve 19 in the valve group 14, thereby realizing that the upper tower body 1 and the lower tower body 2 are alternately in the adsorption state and the desorption state; The built-in control logic 23 of the controller 18 has many advantages. First, it can automatically control the switching of the valve group according to the real-time gas parameters or preset time collected by the sensor group 17, without the need for frequent manual operation, thereby improving the degree of automation and efficiency of operation. Secondly, this automatic control method ensures the accuracy of the upper tower body 1 and the lower tower body 2 alternating in the adsorption and decomposition states, so that the molecular sieve adsorber can stably perform the dual-purpose function of one tower. Furthermore, combined with the data feedback from the sensor group 17, the operating status can be adjusted in time, thereby enhancing the adaptability of the equipment to different working conditions, ensuring the stable and reliable operation of the entire molecular sieve adsorber system, and improving the overall performance and use effect of the system.

[0025] See also Figure 1 、 Figure 2 and Figure 3 The switching valve 19 is a solenoid valve, the control end of which is electrically connected to the controller 18, and the switch of the valve is controlled by the electrical signal output by the controller 18; A signal receiving module is provided at the control end of the solenoid valve, which is connected to the signal output port of the controller 18 via a wired (such as RS485 bus) or wireless (such as Bluetooth) method. The controller 18 generates a switch control signal according to a preset logic, which is encoded and transmitted to the signal receiving module of the solenoid valve through a communication line. After decoding, the module drives the internal coil of the solenoid valve to turn on and off the power, thereby realizing the opening and closing of the valve. In 19, the switching valve is clearly defined as a solenoid valve, and is linked to the controller 18 through an electrical connection, thereby realizing automatic and precise switching of the adsorber state. This design directly controls the solenoid valve switch through the electrical signal output by the controller 18, without manual intervention, thereby improving the system response speed and reliability. Combined with the gas parameters collected in real time by the sensor group 17, the controller 18 can dynamically adjust the valve state according to preset logic or data, so that the upper tower body 1 and the lower tower body 2 are efficiently alternately in the adsorption and decomposition state, thereby optimizing the operating efficiency of the molecular sieve adsorber. At the same time, the precise control of the solenoid valve reduces the risk of gas leakage and improves the safety of the system. Overall, this design enhances the automation and intelligence level of the molecular sieve adsorber, reduces the operation complexity and maintenance cost, and provides an efficient and stable solution for industrial gas separation and purification.

By writing a dedicated storage management software, the raw data collected by the sensor group 17 and the control instructions output by the controller 18 are classified and stored according to time sequence and sensor type. At the same time, a data export interface is developed to support exporting data to external storage devices through various methods such as USB and Ethernet, which facilitates subsequent data analysis and processing; The data acquisition module 15 is provided with a data storage unit 23, which has many advantages. First, the data storage unit 23 can comprehensively store the raw data collected by the sensor group 17 and the control instructions output by the controller 18, providing rich data support for subsequent data analysis, system optimization and troubleshooting. Secondly, the support for data export function allows data to be easily transferred to other devices or systems for in-depth processing, thereby improving the utilization value of the data. In addition, this design helps to establish a data archive of the system, facilitates tracking the system operation history, provides a strong guarantee for the long-term stable operation and maintenance of the system, and also enhances the traceability and management efficiency of the system.

The input unit 25 can be set to a touch screen or a keyboard and mouse combination. The operator can modify the preset parameters in the pop-up parameter modification window by clicking on the touch screen or inputting control commands on the keyboard, thereby realizing convenient operation; The human-computer interaction module 16 includes a display unit 24 and an input unit 25, which have significant benefits.

[0028] See also Figure 1 、 Figure 2 and Figure 3 The monitoring module 13 further includes an alarm unit 26, which is electrically connected to the controller 18. When the parameters collected by the sensor group 17 exceed a preset range, the controller 18 controls the alarm unit 26 to issue an alarm signal. Normal range thresholds for various gas parameters (pressure, temperature, flow) are pre-set in the controller 18. The sensor group 17 collects the gas parameters in the pipeline in real time and transmits them to the controller 18. The controller 18 compares the received parameters with the preset thresholds. If any of the collected pressure, temperature, or flow parameters is higher than the upper threshold or lower than the lower threshold, it is determined to be out of the preset range, and the alarm unit 26 is triggered to issue an alarm signal. The monitoring module 13 is provided with an alarm unit 26 and is electrically connected to the controller 18, which has many advantages. First, it can detect abnormalities in time.
