Problems solved by technology

This invention solves the above problems. Although the invention has a hydrophilic coating, it has the following disadvantages: 1. Due to the small distance between the plates, gaseous pollutants will adhere to the parallel plates, which will pollute subsequent sampling and be very inconvenient to clean
2. There is no automatic collection device in the sampling process, which makes it difficult to meet the 24-hour observation needs of the meteorological industry

Abstract

The invention discloses a rare earth modified nano coating glass plate self-cleaning gas collecting device, and belongs to the fields of atmospheric sciences and environmental sciences. The gas collecting device comprises a gas inlet pipe, a gas collector, a gas outlet pipe, a peristaltic pump, a gathered liquid tank, a feeding pipe, a liquid inlet peristaltic pump, a collected liquid tank, a discharging pipe and a liquid outlet peristaltic pump, wherein the gas inlet pipe is connected with a gas inlet of the gas collector; the gas outlet pipe is connected with a gas outlet of the gas collector; the peristaltic pump is connected with the gas outlet pipe; the gathered liquid tank is connected with a gathered liquid pipeline on the gas collector by virtue of the feeding pipe; and the collected liquid tank is connected with a collected liquid pipeline on the gas collector by virtue of the discharging pipe. The rare earth modified nano coating glass plate self-cleaning gas collecting device disclosed by the invention has the characteristics of being easy to operate, high in gas collection efficiency and the like, and the gas colleting device can be widely applied to the fields of monitoring and research of gaseous pollutants in weather and environment industries as well as occasions in which gaseous pollutants are required to be effectively and rapidly separated from particle components.

Description

technical field [0001] The invention relates to the fields of atmospheric science and environmental science, in particular to a self-cleaning gas collection device for a rare-earth modified nano-coated glass plate. The device has the advantages of semi-continuous and self-cleaning properties in gas collection. Background technique [0002] The existence of air pollutants in the atmosphere is determined by their physical and chemical properties and their formation process, and meteorological conditions also have a certain impact on them. Pollutants in the atmosphere can be roughly divided into two categories: gaseous and aerosol, both of which are mixed in the atmospheric environment. In order to accurately analyze the characteristics of these two pollutants, it is necessary to effectively separate the components and concentrations of gaseous pollutants and aerosol pollutants. Because the diffusion rates of gaseous pollutants and aerosol pollutants are very different, many r...
