Analysis and detection device for gases in environment

Abstract

The invention discloses a gas analysis and detection device in the environment, which comprises a casing, an air inlet is arranged on the top of the casing, a valve matching the air inlet is arranged on the top of the air inlet, and a filter is arranged above the inside of the casing. The filter screen divides the interior of the shell into a filter chamber and a detection chamber. The top of the filter chamber is located on the side of the air inlet with a suction fan, and the bottom of the filter chamber is provided with a filter mesh. The filter chamber and the detection chamber are detachable. Connection, the bottom of the filter chamber is symmetrically provided with inserts on both sides, and the top of the insert is provided with a stopper. The stopper is located at the bottom of the filter chamber, and the diameter of the stopper is larger than the diameter of the insert. A slot matching the plug is provided at the corresponding position, and an insertion port matching the stop is provided on the top of the slot. Beneficial effects: the filter screen can be cleaned in time conveniently, which is more conducive to the cleanness and tidiness of the gas environment inside the housing, and the detection head can fully contact the gas in the housing, thereby greatly improving the detection accuracy.

Description

technical field [0001] The invention relates to the technical field of environmental quality detection, in particular to a gas analysis and detection device in the environment. Background technique [0002] With the improvement of people's living standards and the obvious improvement of living conditions, interior decoration has become more and more common. The use of various decoration materials and more daily-use chemicals have entered the room, increasing the sources and types of indoor pollutants. Indoor air is more polluted than outdoor air. According to statistics, about 80% of people's life is spent indoors, so the quality of indoor air directly affects the health of everyone, and it has increasingly attracted the attention of the whole society. At the same time, the research and development of indoor air quality detection is also an imperative work. [0003] At present, there are roughly two types of instruments for testing various indicators in the air in China: o...

Problems solved by technology

[0003] At present, there are roughly two types of instruments for testing various indicators in the air in China: one is for testing one indicator and displays data; the other is comprehensive testing, which can collect data for various indicators. This kind of instrument is mostly used for measuring decoration Harmful gases, environmental pollution, etc. are produced, and most of the air quality testing is large-scale testing equipment, such as equipment for testing urban air pollution index, which is not convenient to carry. At the same time, the air often contains a large number of dust particles and other impurities, which directly affect the environment. The detection of the gas in the gas will lead to low detection efficiency. At the same time, the probe is fixed and cannot effectively fully contact the gas in the detection room, which will also greatly reduce the detection efficiency.
