Description

Technical Field

[0001] The utility model belongs to the technical field of gas generation, and in particular relates to an intelligent tracer hydrogen-nitrogen gas generating device. Background Art

[0002] The generating device is mainly aimed at simulating gas components required in laboratories and various environments. It is a device that sets the mixed output according to the proportion. The main core component is the mass flow controller. It uses its high precision and high accuracy to accurately control the input amount of each gas component, and outputs it after passing through the professionally designed and produced generating chamber. The hydrogen-nitrogen generating device is a device that adjusts hydrogen and nitrogen through a mass flow controller to obtain a stable hydrogen-nitrogen mixed gas with a certain proportion, which can be adjusted as needed.

[0003] For example, the "a hydrogen-nitrogen mixed gas distribution device" with the authorization announcement number "CN202022991512.2" "comprises a gas distribution equipment main body, and a movable structure arranged on both sides of the gas distribution equipment main body, characterized in that the movable structure comprises: a universal wheel, the universal wheel is installed at the bottom end of the L-shaped support rod, and the two groups of the support rods are respectively arranged in the grooves opened on both sides of the gas distribution equipment main body; the utility model is provided with a movable structure in the grooves opened on both sides of the gas distribution equipment main body, and the movable structure consists of a support rod and a universal wheel at its end, and the rolling of the universal wheel is used to facilitate the movement of the device, and at the same time, a hydraulic cylinder is provided on the top wall of the groove, and under the drive of the hydraulic cylinder, the extrusion plate at its output end moves downward, and the support rod is squeezed downward, and the universal wheel is used to contact the ground to support the gas distribution equipment main body, and when it is not needed to move, the universal wheel can be retracted into the groove, which is convenient and practical.

[0030] The specific implementation method is as follows: the driving motor 83 is started to drive the stirring shaft 84 and the stirring roller 85 to rotate, so that the tracer and the fluorescent agent are fully mixed, and then the two air pumps 20 inject a fixed ratio of hydrogen and nitrogen gas into the inside of the generating box 11 through the two gas pipes 12. At the same time, the metering pump 81 injects the tracer and fluorescent agent mixed in the dosing tank 6 into the generating box 11. Since the hydrogen and nitrogen gases are very likely to generate high temperature and high pressure during the generation process, the fluorescent tracer 82 can be used to perform fluorescent survey on the inside of the generating box 11, thereby effectively preventing the device from leaking during the gas generation process.

[0031] Working principle: First, before using the generating device, the piston rod of the hydraulic cylinder 14 is extended to move the movable plate 15 downward. When the four universal wheels 16 support the device, it is convenient for the staff to carry the generating device. Then, the suction volume of the two air pumps 20 is adjusted respectively to make the hydrogen and nitrogen mixed in a ratio of 5:95. When the generating device is in operation, a proper amount of tracer and fluorescent agent is added to the inside of the dosing tank 6, and the drive motor switch is turned on at the same time. The drive motor 83 starts to drive the stirring shaft 84 and the stirring roller 85 to rotate, so that the tracer and the fluorescent agent are fully mixed. Then, the two air pumps 20 inject a fixed ratio of hydrogen and nitrogen gas into the inside of the generating box 11 through the two gas pipes 12. At the same time, the metering pump 81 injects the mixed tracer and fluorescent agent in the dosing tank 6 into the inside of the generating box 11. Since hydrogen and nitrogen gases are very likely to produce high temperature and high pressure during the generation process, Then, the inside of the generating box 11 can be fluorescently surveyed by the fluorescent tracer 82, and the fluorescent position can be captured through a plurality of observation windows 17, thereby effectively preventing the device from leaking during the gas generation process, so as to improve the safety of the hydrogen-nitrogen gas generation process. Then, the condensation pump switch, the cooling fan switch and the refrigeration plate switch on the surface of the switch panel 19 are turned on, and the cooling water source in the condensation box 71 is extracted through the liquid extraction end of the condensation pump 73, and then the cooling water source is injected into the condensation pipe 72 through its liquid outlet end. At the same time, the two cooling fans 74 operate to blow the heat accumulated on the surface of the generating box 11 to the top of the generating chamber 5, and then the heat on the top of the generating chamber 5 is absorbed by the refrigeration plate 75 and quickly discharged through its heat dissipation surface, thereby effectively preventing the high temperature generated during the hydrogen-nitrogen gas generation process from damaging the internal structure of the device. Finally, the generated gas is discharged out of the device by opening the solenoid valve 10.
