Abstract
Description
Technical Field
[0001] The invention relates to the technical field of aerosol particle size detection, and in particular to a toxic aerosol particle size detection and analysis system. Background Art
[0002] As we all know, the size of aerosols ranges from 0.01 to 10 μm. The dispersed phase is small solid or liquid particles, and the dispersion medium is gas. Liquid aerosols are usually called mist, while solid aerosols are usually called smoke1. Aerosol-transmitted viruses generally mix with droplets in the air to form aerosols, which lead to infection after inhalation. In pesticide use scenarios, aerosols come into contact with pesticides to form toxic aerosols contaminated with pesticides. In order to facilitate personnel to wear protective tools with corresponding protection requirements in pesticide use scenarios, personnel are required to use corresponding detectors to detect and analyze the particle size of toxic aerosols in the air, and then use corresponding protective tools according to the particle size data to ensure that personnel will not be affected. However, due to the wide range of pesticide use scenarios, personnel need to detect the particle size of toxic aerosols in the air in different areas. However, during the use of existing toxic aerosol detection instruments, toxic aerosols are easily retained inside the instrument, which will cause the instrument to mix with the residual toxic aerosols during the next test, affecting the detection accuracy of the toxic aerosol particle size. Therefore, it is necessary to propose a solution to this technical problem. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A liquid storage tank 12 and a water storage tank 13 are provided on the support plate, a water storage cavity is provided inside the water storage tank 13, a water inlet pipe 14 is provided on the water storage tank 13, a flushing mechanism is provided between the water storage tank 13 and the two detection slots 3, a liquid outlet mechanism is provided on the liquid storage tank 12, and a liquid discharge mechanism is provided between the liquid storage tank 12 and the two detection slots 3. In this embodiment, a person moves the frame 1 to the scene area where pesticides are used, and uses a fan 11 to allow the air in the area to enter the three-way valve 9 through the air duct 10. The filtering mechanism can block larger particulate impurities in the air, and the air is circulated to one of the two detection slots 3 by using the three-way valve 9. 3, enters the corresponding detection slot 3 through the air inlet pipe 6, and then the personnel use the spectrometer 5 between the detection slot 3 and the top of the detection box 2 to detect and analyze the particle size data of the toxic aerosol, and then open the first valve 8 to discharge the gas in the detection slot 3 from the air outlet pipe 7. The toxic aerosol will still remain in the detection slot 3. Therefore, when the personnel use this structure to detect the toxic aerosol in the air of the next area, the air duct 10 is connected to the air inlet pipe 6 of another detection slot 3 by controlling the three-way valve 9. At this time, the air duct 10 is closed with the air inlet pipe 6 of the first detection slot 3 used, and then the spectrometer 5 of the other detection slot 3 is used to detect the toxic aerosol. To detect the particle size data of the toxic aerosol, during the detection process, the first detection tank 3 is flushed by using the flushing mechanism between the water tank 13 and the detection tank 3, so that the toxic aerosol remaining in the detection tank 3 is discharged into the liquid storage tank 12 along with the water through the discharge mechanism, thereby automatically cleaning the toxic aerosol remaining in the detection tank 3, and then facilitating the next use of the detection tank 3. This can ensure that when the toxic aerosol is detected, the toxic aerosol remaining in the detection tank 3 is prevented from being mixed with the currently detected toxic aerosol for detection, which affects the accuracy of the detected toxic aerosol particle size data. The liquid temporarily stored in the liquid storage tank 12 after flushing can be discharged through the liquid discharge mechanism.
[0026] The flushing mechanism can be any flushing device.

An annular tube 19 is provided on the mounting disk 17. A nozzle 20 is provided between the annular tube 19 and the outer side of the mounting disk 17. A plurality of nozzles 20 are provided and arranged in an annular array. A hose 21 is provided in between. After detecting the toxic aerosol in the pesticide use scenario, a part of the toxic aerosol will remain in the detection tank 3. At this time, the installation disk 17 is moved upward by controlling the lifting mechanism 15, and the installation disk 17 drives the sealing disk 18 to move upward. The installation disk 17 is now located in the detection tank 3, and the fixed disk is located in the cleaning tank. The fixed disk blocks the cleaning tank, and then the water pump 16 is controlled. The water pump 16 draws water in the water storage chamber into the hose 21 through the pumping pipe, and then the water enters the annular tube 19 through the hose 21. Through the annular tube 19 and the nozzle 20 on the outside of the installation disk 17, the detection tank 3 can be sprayed and rinsed. The nozzle 20 is provided with multiple and annular arrays, and the surroundings of the detection tank 3 can be rinsed, so that the toxic aerosol is attached to the water, and then the drainage mechanism is used to discharge the water and the toxic aerosol, thereby greatly reducing the toxic aerosol remaining in the detection tank 3, and ensuring the accuracy of the data of the toxic aerosol detection and analysis when it is used next time.
[0027] The above-mentioned drainage mechanism can be any kind of drainage device. In order to further discharge the liquid used for flushing and cleaning the detection tank 3, the drainage mechanism includes a drainage pipe 22, and the drainage pipe 22 is installed at the top end of the liquid storage tank 12. The drainage pipe 22 extends to the bottom end of the detection tank 3. A second valve 23 is provided between the drainage pipe 22 and the detection tank 3. By opening the second valve 23 on the drainage pipes 22 corresponding to the two detection tanks 3, the liquid used for flushing in the two detection tanks 3 can flow into the liquid storage tank 12 through the drainage pipe 22, so that the liquid used for flushing in the detection tanks 3 can be temporarily stored.

The filter cover 26 is threadedly connected to the threaded ring 27 through the threaded groove. An air inlet pipe 29 is provided on the other side of the filter cover 26. Personnel press the filter mesh layer 28 against the threaded groove, and then thread the threaded groove and the threaded ring 27 to fasten the filter mesh layer 28 in the threaded groove, which is convenient for assembling the filter mesh layer 28. When the filter mesh layer 28 needs to be disassembled for mechanical inspection and replacement, the filter cover 26 is rotated in the opposite direction to facilitate the removal and replacement of the filter mesh layer 28.
[0030] The above-mentioned frame 1 is not easy to move. In order to further facilitate the movement of the frame 1, a universal wheel 30 is provided at the bottom end of the support plate. There are multiple universal wheels 30, and a wheel lock is provided on the universal wheel 30. The frame 1 can be easily moved through multiple universal wheels 30, so that the structure can be easily moved to the area that needs to be detected.
[0031] In order to further facilitate personnel to control the opening and closing of the valves, the three-way valve 9, the first valve 8, the second valve 23 and the third valve 25 are all electric valves, which can be used to adjust the flow direction of the three-way valve 9 and to open and close the first valve 8, the second valve 23 and the third valve 25.
[0032] The lifting mechanism 15 can be any kind of lifting device. To further facilitate the lifting and lowering of the linearly movable mounting plate 17, the lifting mechanism 15 is an electric telescopic rod, through which the linearly movable mounting plate 17 can be lifted and lowered. The electric telescopic rod has the characteristic of high moving accuracy, thereby facilitating accurate and stable mounting of the mounting plate 17 at one end.
