An alarm system for self-identification of abnormalities in chemical experiments based on information technology

Abstract

The invention discloses an alarm system based on information technology for self-recognition of abnormalities in chemical experiments, which belongs to the technical field of chemical experiment monitoring and identification alarms. The shunt tube diverts the gas flow into the two detection chambers, and the two gas detection sensors perform simultaneous and independent detection, which effectively improves the accuracy of the detection results. After the gas detection sensor detects parameters such as gas concentration, if the parameters exceed the set After the value is set, the alarm is realized through the informationization of the controller and data module to effectively warn the technicians whether the laboratory environment is dangerous, and the detected gas is exported from the deflector hole on the deflector plate and then Layered adsorption filtration is carried out by the filter layer, and the harmless gas after filtration is discharged into the laboratory, so as to effectively improve the personal safety of technicians during the experimental work.

Description

technical field [0001] The invention relates to the field of chemical experiment monitoring, identification and alarm technology, more specifically, to an information technology-based alarm system for self-identification of chemical experiment anomalies. Background technique [0002] The normal operation of the production process of chemical products, the control and guarantee of product quality and output are inseparable from the adaptation and normal operation of various chemical equipment. The selection of chemical equipment must meet the needs of chemical production through careful calculation, design, processing, manufacturing and selection of the entire chemical production process; but in the production process of chemical products, a large number of correlations are first needed chemical experiments. [0003] In the chemical laboratory, it is often necessary to store and use various chemical reagents, including some dangerous, volatile, and toxic chemical reagents, a...

Problems solved by technology

[0003] In the chemical laboratory, it is often necessary to store and use various chemical reagents, including some dangerous, volatile, and toxic chemical reagents, and these chemical reagents are generally stored in reagent cabinets. In the process, it is inevitable that some toxic and harmful gases will be discharged into the air of the laboratory and reagent storage due to reagent volatilization and leakage; at the same time, when technicians perform experimental operations, if the experiment is wrong, a large amount of harmful gases will overflow When the time comes, the entire laboratory will be filled with a large amount of harmful gas, especially for some odorless and colorless harmful gases, even if they leak, the technicians will not be easy to detect, which will affect the personal safety of the technicians
