Information technology-based chemical experiment abnormal shape self-identification alarm system

Abstract

The invention discloses an information technology-based alarm system for chemical experiment abnormal shape self-identification. The invention belongs to the technical field of chemical experiment monitoring identification alarm. Gas in a laboratory is pumped into the gas detection tank through a drainage machine; gas is shunted and guided into the two detection cavities through the two shunting pipes; two gas detection sensors carry out synchronous and independent detection, so the accuracy of a detection result is effectively improved; the gas detection sensors detect parameters such as gasconcentration and the like; if the parameters exceed a set value; the alarm of an alarm is realized in an informationized manner through a controller and a data module; and the detected gas is guidedout through flow guide holes in a flow guide plate and then is subjected to layered adsorption and filtration through the filter layer, and the filtered harmless gas is discharged into a laboratory such that the personal safety of the technicians in the experiment working process is effectively improved.

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
