[0021] Example 1
[0022] like Figure 1 As shown in the figure, this embodiment illustrates an integrated nitrogen humidification device, including a base 1, a tank 5, a gas-liquid separator 8, a pipeline filtration system, and a monitoring system. The tank 5 is fixedly mounted on the base 1. A wet nitrogen manual valve 16 and a nitrogen inlet valve 7 are sequentially installed on the pipeline at the air inlet end of the tank 5. A sight glass 3 is installed on one side of the tank 5 for easy observation of the internal condition of the tank 5. A filter element 14 is installed inside the tank 5, and the air inlet of the tank 5 is connected to the filter element 14. The filter element 14 is made of stainless steel, titanium, or PTFE. The tank 5 is also equipped with a jacket 13. The medium in the jacket 13 is selected from -7℃ brine, -25℃ brine, and steam. The tank 5 stores process water, purified water, ethanol, or methanol, etc., as process solvents. The gas-liquid separator 8 is fixedly installed at the top of the tank 5. The outlet of the gas-liquid separator 8 is connected to the inlet of the pipeline filtration system. The outlet of the pipeline filtration system is equipped with a nitrogen outlet valve 11. The nitrogen inlet valve 7, nitrogen outlet valve 11, wet nitrogen manual valve 16, and dry nitrogen manual valve 15 are all any one of the following: ball valve, solenoid valve, diaphragm valve, needle valve, plug valve, or PCV valve. The monitoring system is fixedly installed on the pipeline filtration system to monitor the temperature, humidity, and air pressure within the pipeline filtration system.
[0023] The pipeline filtration system includes a first pipeline filter 6 and a second pipeline filter 12. The first pipeline filter 6 and the second pipeline filter 12 are connected in series at the rear end of the gas-liquid separator 8 via pipelines. A branch pipeline is provided between the first pipeline filter 6 and the second pipeline filter 12, and a dry nitrogen manual valve 15 is installed on the branch pipeline. The outlet of the nitrogen inlet valve 7 is connected to both the wet nitrogen manual valve 16 and the dry nitrogen manual valve 15 via a three-way valve. With this configuration, part of the dry nitrogen enters the tank 5 for humidification, while the other part passes through the dry nitrogen manual valve 15 and mixes with the humidified wet nitrogen in the second pipeline filter 12 to achieve the desired target humidity. Then, both are discharged together through the nitrogen outlet valve 11 to the target nitrogen receiving device.
[0024] The integrated nitrogen humidification device disclosed in this application is also equipped with a PLC control cabinet 4. The PLC control cabinet 4 is connected to the tank 5, the pipeline filtration system and the monitoring system via electrical signals. The opening and closing of the valves in the tank 5, the first pipeline filter 6 and the second pipeline filter 12 can be directly controlled by the PLC control cabinet 4. The monitoring system includes a pressure gauge 10 and a thermometer and hygrometer 9. In this embodiment, both are digital displays, and the detected values are transmitted to the display panel of the PLC control cabinet 4 in real time. The pressure gauge 10 is fixedly installed on the first pipeline filter 6 and the thermometer and hygrometer 9 is fixedly installed on the second pipeline filter 12. The operator can adjust the operation in a timely manner according to the temperature, humidity and pressure values.
[0025] The base 1 has casters fixedly installed at its four bottom corners, and a handle fixedly installed on one side. The placement of the casters and handle...
[0026] This facilitates the relocation of the device, increasing its convenience.
[0027] Operating Procedure: The operator opens the nitrogen inlet valve 7. Part of the nitrogen enters the tank 5 through the pipeline via the wet nitrogen hand valve 16, where it is humidified by the process solvent. It then flows into the gas-liquid separator 8 for humidity adjustment, and then through the pipeline into the first pipeline filter 6. The pressure at this point is fed back to the operator via the pressure gauge 10, allowing for real-time adjustments. The wet nitrogen exiting the outlet of the first pipeline filter 6 merges with another portion of dry nitrogen from the nitrogen inlet valve 7 via the dry nitrogen hand valve 15, and together they enter the second pipeline filter 12 for further humidity adjustment. The humidity is fed back to the operator or PLC control cabinet 4 via the thermo-hygrometer 9. The operator or PLC control cabinet 4 can adjust the target humidity by adjusting the gas flow rates of the wet nitrogen hand valve 16 and the dry nitrogen hand valve 15. Finally, the wet nitrogen enters the nitrogen receiving device through the nitrogen outlet valve 11, completing the nitrogen drying process.
[0028] In summary, the above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
