Description

Timing sampling equipment for air detection and measurement

Technical Field

The utility model relates to the technical field of air detection sampling, in particular to timing sampling equipment for air detection and measurement.

Background

Air refers to the gas surrounding the earth, which maintains the survival of humans and living beings, and air quality detection refers to the detection of the quality of air. The quality of the air reflects the concentration of pollutants in the air. Air pollution is a complex phenomenon, and air pollutant concentrations are affected by many factors at specific times and locations. The amplification of man-made pollutant emissions from stationary and mobile pollution sources is one of the most important factors affecting the quality of air, including the exhaust gases of vehicles, ships, airplanes, industrial production emissions, residential life and heating, waste incineration, etc. The development density, topography, weather and the like of the city are also important factors influencing the air quality, the air quality detection means that the quality of the air is detected, and in the detection process, the air needs to be sampled first.

The common sampling equipment for air detection is characterized in that an air suction structure (such as a suction fan and the like) starts to suck outside air into the sampling equipment, so that the air flows along a pipeline in the sampling equipment and enters the sampling structure (such as a sampling tube or a sampling bottle) through an air outlet end of the pipeline, and the sampling equipment is the common sampling equipment structure for air detection and the use mode. Traditional air detection surveys and uses sampling equipment, and current air detection is with regularly sampling equipment degree of automation is low, and inconvenient automatic air that samples every period after will regularly is separately deposited, leads to being difficult to guarantee the accuracy of detection. The sampling equipment for partial air detection realizes the timing starting of the air suction structure by adding a time-setting structure (such as a timer) inside, sets a plurality of groups of sampling structures and sets an air inlet hole, and a movable air guide cover is arranged at the air inlet hole of the sampling structure. In this way, although the air can be sampled and stored separately at regular time, the air guide cover is communicated with the air inlet holes of the sampling structure only by moving, so that the air inlet holes of the sampling structure cannot be additionally provided with a sealing structure and the like, and air can enter the inside of a plurality of groups of sampling structures at will, so that inaccurate air detection results of different time periods occur.
