Abstract

The invention relates to a system and a method for rapidly estimating the total content of harmful gases in air. The system comprises a detection box, an air suction pump arranged in the detection box, a first dryer, a cyclone dust collector, an inhalable particle cutter, a harmful gas absorption bottle, a second dryer, a first electronic analytical balance, a second electronic analytical balance, and a control panel arranged outside the detection box. An air inlet of the air suction pump extends out of the detection box through a pipeline, an exhaust port of the air suction pump is sequentially communicated with the first dryer, the cyclone dust collector, the inhalable particle cutter, the harmful gas absorption bottle and the second dryer through pipelines and then extends out of the detection box, the harmful gas absorption bottle is filled with a potassium permanganate aqueous solution, the harmful gas absorption bottle and the second dryer are respectively and correspondingly arranged on weighing platforms of the first electronic analysis balance and the second electronic analysis balance, and the air suction pump, the first electronic analysis balance and the second electronic analysis balance are electrically connected with the control panel. The system has the advantages that the structure is simple, and the total content of harmful gas in the air can be quickly and relatively accurately estimated.

Description

technical field [0001] The invention belongs to the field of harmful gas detection, and in particular relates to a system and method for quickly estimating the total content of harmful gases in the air. Background technique [0002] Harmful gases in the air refer to gases that have adverse effects on the health of humans or animals, or that have no effect on the health of humans or animals, but make humans or animals feel uncomfortable and affect the comfort of humans or animals. Common harmful gases in the air are nitrogen oxides (nitrogen monoxide and nitrogen dioxide), sulfur dioxide, sulfur trioxide, hydrogen sulfide and formaldehyde. Because there are many types of harmful gases, it is generally difficult to quickly estimate the total content of harmful gases in the air through simple methods in the prior art, and therefore it is also impossible to quickly and roughly judge the air pollution situation. Contents of the invention [0003] The technical problem to be so...
