A chemical laboratory environment detection and monitoring device and monitoring method thereof

Abstract

The invention discloses a chemical laboratory environment detection and monitoring device and a monitoring method thereof, comprising a detection box, a gas detector, and a buzzer. The outer wall of the detection box is provided with a through groove, and the inner wall of the through groove is A sealing groove is opened on the top, and a purification mechanism is slidably connected to the inner wall of the sealing groove. The purification mechanism is pressed against the inner wall of the through groove. The gas detector is fixedly installed on the inner wall of the detection box. A shaft sleeve is fixedly connected to the inner side wall of the detection box, a connecting rod is slidingly connected to the inner side wall of the shaft sleeve, an impact plate is fixedly connected to the outer side wall of the connecting rod, and a pulley is fixedly connected to the end of the connecting rod. Rope, the fan rotates to inhale the gas in the chemical laboratory into the inside of the detection box through the intake pipe. With the inhalation of the gas, the harmful gas in the air can be detected by the gas detector, so as to avoid the harmful gas in the chemical laboratory exceeding the standard. bodily harm to persons.

Description

technical field [0001] The invention relates to the technical field of environmental detection and monitoring, in particular to a chemical laboratory environmental detection and monitoring device and a monitoring method thereof. Background technique [0002] The chemical laboratory is an important place to provide chemical experimental conditions and conduct scientific inquiry. There are a large number of instruments: iron stand, asbestos net, alcohol lamp and other experimental tools. There is usually a chemical cabinet with commonly used chemicals in the medicine cabinet. [0003] The conduct of chemical experiments often produces toxic gases, such as nitric oxide, nitrogen dioxide, sulfur dioxide and benzene gases, etc. In the chemical laboratory where chemical experiments are often carried out, there are toxic gases, and due to the complexity of chemical experiments. , The composition of toxic gas is also more complex, which will cause great harm to the health of the s...

AI Technical Summary

Problems solved by technology

[0003] The conduct of chemical experiments often produces toxic gases, such as nitric oxide, nitrogen dioxide, sulfur dioxide and benzene gases, etc., and in chemical laboratories where chemical experiments are often carried out, there are toxic gases, and due to the complexity of chemical experiments , the composition of toxic gas is also relatively complex, which will cause great harm to the health of the staff, and even threaten life safety. Therefore, it is very necessary to detect toxic gases in chemical laboratories

Heating is often required in chemical reactions to speed up the reaction, and many chemical reagents are flammable, which can easily lead to fires

[0004] Traditional chemical laboratory environmental detection and monitoring devices can only detect the gas content in the laboratory, but cannot filter harmful gases in the laboratory, and the long-term exposure of the filter to or reduce the filtration efficiency of the filter to harmful gases, At the same time, when a fire breaks out in the laboratory, there is a lack of timely warning of the fire and effective fire extinguishing, which makes the fire bigger and bigger, resulting in personal and property damage.
