Big bubble absorption tube for environmental atmosphere detection

Technical Field

The utility model relates to the technical field of large-bubble absorption tubes, in particular to a large-bubble absorption tube for environmental atmosphere detection.

Background

Atmospheric sampling refers to a method for collecting samples of pollutants or polluted air in the atmosphere, and the collection method is a method for gathering pollutants with lower concentration in the atmosphere by allowing a large amount of air to pass through a liquid absorbent or a solid adsorbent, such as an air suction method and a filter membrane method. Another type is to collect the air containing the contaminants with containers (glass bottles, plastic bags, etc.).

When the concentration of the component to be detected in the atmosphere is higher or the analysis method is very sensitive, a direct sampling method is adopted, common sampling containers comprise an injector, a plastic bag, a plurality of fixed containers and the like, and the measured instantaneous concentration or the average concentration in a short time of the pollutant in the atmosphere; when the concentration of the measured component in the atmosphere is low, a concentration sampling method is adopted, wherein the concentration sampling method comprises a solution absorption method, a small packed column sampling method, a low-temperature condensation method and a filter material sampling method, and the average concentration of the pollutants in the atmosphere in the sampling time is measured by the method. According to the purpose and the field condition of sampling, the atmosphere sampling selects a proper sampling mode to ensure that the collected sample is representative. The former measures the average concentration of the pollutants in the atmosphere within the sampling time; the latter measured instantaneous concentrations or average concentrations over a short period of time. The sampling mode is determined according to the purpose of sampling and the field situation. The sample should be representative. The sampling efficiency is high, the operation is simple and convenient, and the subsequent analysis and measurement are convenient to obtain reliable basic data of atmospheric pollution.

At present the sampling of the big bubble absorption tube of universal adoption when detecting environment atmosphere, but big bubble absorption tube has the inconvenient scheduling problem of removing and placing after accomplishing the sampling, leads to consuming a large amount of manpower and materials in the experiment.
