Abstract

The invention discloses a teaching laboratory air detection and purification device, which comprises a device body, wherein a gas analysis instrument is arranged inside the device body; a sampling pipe is arranged at the end side of the gas analysis instrument; a filtering screen is arranged inside the sampling pipe; a first fan is arranged at one side of the gas analysis instrument; one side of the first fan is connected with a first air inlet pipe, the first fan is connected with a first liquid storage tank through a first exhaust pipe; a second fan is arranged at one side of the first fan;one side of the second fan is connected with a second air inlet pipe; the second fan is connected with a second liquid storage tank through a second exhaust pipe; the first liquid storage tank and thesecond liquid storage tank are connected through a mother pipe. The content of each ingredient of toxic gas in the air is detected through the gas analysis instrument; the guidance and purification on the toxic gas in the air can be fast and conveniently realized by controlling the operation of the first fan and the second fan.

Description

Technical field [0001] The invention relates to the technical field of air detection and purification in environmental protection, and more specifically, to an air detection and purification device for teaching laboratories. Background technique [0002] Teaching laboratory is mainly a place where students are taught by way of experiment display, including physics laboratory and chemical laboratory. As we all know, in the process of experimental teaching, because of the frequent need for centrifugation, stirring, mixing, violent shaking and other experimental operations, harmful gases are often generated during the above-mentioned experimental process. Due to the large number of students, the harmful gases produced are often not effectively discharged. , Which damages the safety of experiment operators and students. On the other hand, the existing air purification often only passively performs ventilation operations, which will cause harmful gases to be discharged into the atmos...
