Aeration liquid surface gas emission quantifying device

Abstract

The utility model discloses an aeration liquid surface gas emission quantifying device which comprises a square sampling cylinder with an opening in the top end; the sampling barrel is used for transmitting gas; the fixed fence strip is arranged on the inner side of the opening of the sampling barrel; the floating block is I-shaped, a square hole is formed in the middle of the floating block, and the sampling barrel is sleeved with the floating block; the collecting bag is used for collecting gas output from the sampling barrel; the outer frame is arranged at the end, away from the floating body, of the collecting bag, and the end, close to the floating block, of the outer frame is connected with the floating body; the control assembly is arranged at the end, away from the collecting bag, of the outer frame. The controller is used for controlling gas collection of the collection bag; the hydraulic push rod is arranged at the end, away from the collecting bag, of the outer frame and can push the pressing plate to extrude the sampling bag. By optimizing the structure of the sampling device, the defects that a sampling zero point and a sampling end point are difficult to accurately determine, the portability is poor and the like when a traditional gas sampling device is used on the water surface are overcome, and the sampling accuracy is greatly improved.
