Abstract

The invention discloses an atmospheric pollution gas detector, which comprises a machine body, wherein an air inlet is formed in the left end of the machine body; the left end of the air inlet is connected with an air inlet pipe; an induced draft fan is mounted at the left end in the machine body at a position corresponding to the air inlet; a mounting groove is formed in the bottom end in the machine body; a gas detection sensor is mounted in the mounting groove; an exhaust outlet is formed in the right end surface of the machine body; a first plugging mechanism is arranged at the right end of the exhaust outlet; and the top end of the machine body is provided with a fresh air opening, the top end of the fresh air opening is provided with a second plugging mechanism, the bottom end of thefresh air opening is provided with an air inlet fan, and the fresh air opening is internally provided with an activated carbon filtering layer. The atmospheric pollution gas detector is simple in structure, low in manufacturing difficulty and low in cost, can guarantee the cleanness of the interior of the machine body when not in use, and improves the detection precision.

Description

technical field [0001] The invention relates to the technical field of gas detection equipment, in particular to an air pollution gas detector. Background technique [0002] Gas detector is an instrumentation tool for gas leakage concentration detection, including: portable gas detector, hand-held gas detector, fixed gas detector, online gas detector, etc. Gas sensors are mainly used to detect the types of gases existing in the environment. Gas sensors are sensors used to detect the composition and content of gases. It is generally believed that the definition of gas sensors is based on the classification of detection targets, that is to say, any sensor used to detect gas composition and concentration is called a gas sensor, regardless of whether it uses physical methods or chemical methods. For example, sensors that detect gas flow are not considered gas sensors, but thermal conductivity gas analyzers are important gas sensors, although they sometimes use roughly the same ...
