Abstract

The invention discloses a device for achieving constant-volume proportional dilution. The device comprises a constant-volume tube, a quantifying loop, a mixing bottle, an air pump and a solenoid valve assembly; liquid to be diluted and diluting liquid are pumped to the constant-volume tube and the quantifying loop separately through a pressure difference generated by switching on or switching off the air pump and the solenoid valve assembly, and the mixing bottle is used for mixing the liquid to be diluted and the diluting liquid. The invention discloses a method for achieving constant-volume proportional dilution. A novel constant-volume tube and quantifying loop combining technology and an air pump and solenoid valve combining technology are introduced, and online rapid and precise dilution of various water sources such as ground surface water, sewage and industrial waste water is achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and water environment monitoring and analysis, and in particular relates to a constant-volume proportional dilution device and method, which are used for the automatic online processing process of proportional dilution pretreatment of water quality online instruments. Background technique [0002] At present, a number of national policies strongly support online monitoring equipment for environmental protection instruments. As the environmental protection instrument market enters a stage of rapid development, environmental protection instruments have also exposed some problems, such as domestic pollution sources and other water sample matrices. The structure of the processing device is relatively complex and easy to block, resulting in a large amount of maintenance and high maintenance costs; the limitation of the instrument range makes it impossible to monitor water samples with ultra-hi...
