Problems solved by technology

[0003] Nitrogen dioxide is one of the causes of acid rain. High-temperature combustion and exhaust emissions will produce nitrogen dioxide. Therefore, it is necessary to detect the content of nitrogen dioxide near the factory. The current detection devices use sensors for detection, but the service life of the sensors is short , high requirements on the use environment, and expensive

Abstract

The invention discloses a detection device for nitrogen dioxide and a use method thereof, which belong to the field of environment detection. The device comprises a shell; an air inlet pipe is embedded in the side wall of one side of the shell; and an air extractor is arranged in the air inlet pipe. The nitrogen dioxide in the air can be detected, nitrogen dioxide is determined by using a naphthalene ethylenediamine hydrochloride spectrophotometric method, the detection result is more visual and accurate, the absorption liquid can be replaced, and therefore, the device can be repeatedly used and has enough service life; the hemispheroid shell is driven by a driving motor to rotate, the hemispherical shell is used for blowing air into the volumetric flask, the air absorption speed is increased, the reaction efficiency is improved, the pressing plate is driven to move downwards through rotation of the screw rod and limitation of the telescopic rod, the pressing plate presses a silicone tube to the bottom plate, circulation of the silicone tube is blocked, the situation that a solution is sucked back is prevented, and the whole device is simple in structure, low in cost, high in stability and capable of being repeatedly used.

Description

technical field [0001] The invention relates to the field of environmental detection, more specifically, to a detection device for nitrogen dioxide and a use method thereof. Background technique [0002] The quality of air quality reflects the concentration of pollutants in the air. The emission of man-made pollutants from fixed and mobile pollution sources is one of the most important factors affecting air quality, including the exhaust of vehicles, ships, aircraft, and industrial enterprises. Emissions, residential living and heating, waste incineration, etc. [0003] Nitrogen dioxide is one of the causes of acid rain. High-temperature combustion and exhaust emissions will produce nitrogen dioxide. Therefore, it is necessary to detect the content of nitrogen dioxide near the factory. The current detection devices use sensors for detection, but the service life of the sensors is short , high requirements on the use environment, and expensive. Contents of the invention ...
