Embodiment 1

[0047] Such as Figure 1-7 As shown, the present embodiment provides a fully automatic fog water sampler based on sensor control, including a variable speed fan 1, a steady flow box 2, a filter screen 3 and an air duct, wherein a variable speed fan 1 is arranged at one end of the air duct, and the variable speed fan 1 A network camera 6 is set on the air duct on the upper side, a visibility sensor is set on the network camera 6, a filter screen 3 is set at the other end of the air duct, a water collection tank 4 is set on the lower side of the filter screen 3, an integrated control terminal, a variable speed fan, and a network camera are set on the upper side of the air duct and visibility sensors are connected to the integrated control terminal.

[0048] The air velocity produced by the variable speed fan 1 is in two gears, 4m / s and 6m / s respectively.

[0049] A collecting device 11 is arranged on the lower side of the sump 4 .

[0050] The collection device 11 includes a c...

Embodiment 2

[0067] A fully automatic fog water sampler based on sensor control, the structure is as described in Embodiment 1, the difference is that the steady flow box 2 is vertically arranged inside the air duct, and the cross section of the steady flow box is evenly arranged to be hexagonal The ventilation holes, the length of the six sides of the ventilation holes are all 4mm, and the mist inhaled by the variable speed fan is stabilized through the flow stabilization box to ensure that the mist passes through the filter screen evenly and improves the collection effect.

Embodiment 3

[0069] A fully automatic fog water sampler based on sensor control, the structure is as described in Embodiment 1, the difference is that the filter screen 3 includes a frame and braided wires, and the braided wires are interlaced in the frame, and the braided wires are 0.5mm in diameter. PTFE rope, the hole spacing of the filter screen is 1.8mm.

[0070] The frame is coated with polytetrafluoroethylene coating, and the lower end of the frame extends into the sump by 3mm or more. By setting the polytetrafluoroethylene coating on the frame and using polytetrafluoroethylene rope, the trace elements in the sample are avoided from fogging. Droplet impact adsorption causes loss, and the filter screen is set in 6 rows. The filter screen is set obliquely, and the included angle between the filter screen and the vertical plane is 37°.

Abstract

The invention relates to a full-automatic fog water sampler based on sensor control and a using method thereof, which belong to the technical field of environment detection. The sampler comprises a variable-speed fan, a steady-flow box body, a filter screen and an air duct, wherein the variable-speed fan is arranged at one end of the air duct, a network camera is arranged on the air duct on the upper side of the variable-speed fan, a visibility sensor is arranged on the network camera, the filter screen is arranged at the other end of the air duct, a catch basin is arranged at the lower side of the filter screen, an integrated control terminal is arranged on the upper side of the air duct, and the variable-speed fan, the network camera and the visibility sensor are all connected to the integrated control terminal. The sampler is applied to external field monitoring, the fog water sample of the whole fog event is automatically collected, the sampling difficulty of atmospheric environmental science workers and the difficulty of later data processing are reduced, and long-period automatic sampling is realized.

Description

technical field [0001] The invention relates to a fully automatic fog water sampler based on sensor control and a using method thereof, belonging to the technical field of environmental detection. Background technique [0002] Fog is an aerosol composed of tiny liquid droplets and ice crystal particles suspended in the near-surface atmosphere, and is an important medium for the transmission, adsorption, and reaction of pollutants in gaseous pollutants and dry and wet deposition. In addition, the places where fog forms in foggy weather are mostly located in high mountains and ocean areas with changeable meteorological conditions, and the time of fog formation is uncertain, and it mostly occurs at night. In the field of atmospheric environmental science, collecting fog water samples from the entire fog event is crucial for the analysis and research of trace components and pollutants in the samples. Due to the complexity of the fogging time and fogging location, there is curren...
