A laboratory air quality automatic control system

Abstract

The invention relates to a laboratory air quality automatic control system. The laboratory air quality automatic control system comprises a data acquisition system, a central control system, an external exhaust system and an access control system. The data acquisition system acquires waste gas concentration data in a laboratory in real time and sends the waste gas concentration data to the centralcontrol system. The central control system receives the acquired waste gas concentration data in real time and analyzes whether or not an acquired waste gas concentration exceeds the standard in realtime according to preset waste gas concentration data. When the waste gas concentration exceeds the standard, the central control system controls the external exhaust system and the access control system to start. When the waste gas concentration reaches the standard, the central control system controls the external exhaust system and the access control system to close. According to the laboratory air quality automatic control system, waste gas in the laboratory can be treated in time, so that the air quality in the laboratory is ensured, personnel outside the laboratory can be prevented fromentering the laboratory when the waste gas in the laboratory exceeds the standard, and accordingly, the physical health of the personnel outside the laboratory is guaranteed.

Description

technical field [0001] The invention relates to an automatic control system, in particular to a laboratory air quality automatic control system. Background technique [0002] As we all know, various experimental operations in the laboratory will produce a large amount of various exhaust gases, including flammable, explosive, toxic, harmful and other gases. Various laboratory exhaust gases are mixed into the air in the laboratory, which not only seriously damages the laboratory The health of indoor personnel also threatens the safety of the laboratory. If the exhaust gas concentration is too high, it will not only cause poisoning, explosion and other accidents, but also leak from the laboratory to the outside of the laboratory, damaging the external environment of the laboratory and the health of personnel outside the laboratory. [0003] In the existing technology, there is still no ideal automatic control system and measures for harmful gases in the laboratory. Only measur...

Problems solved by technology

If the exhaust gas concentration is too high, it will not only cause poisoning, explosion and other accidents, but also leak from the laboratory to the outside of the laboratory, damaging the external environment of the laboratory and the health of personnel outside the laboratory

[0003] In the existing technology, there is still no ideal automatic control system and measures for harmful gases in the laboratory. Only measures such as opening windows and normally opening fume hoods can be used to reduce the concentration of laboratory exhaust gas, which is neither environmentally friendly nor energy-saving. Good protection of the health of personnel in the laboratory and the protection of personnel and the environment outside the laboratory, but there are still potential safety risks
