Chemical detection system

Abstract

The invention relates to a chemical detection system. The chemical detection system includes a detector, a reagent storage device, a liquid pumping pipe, a waste liquid collecting device and a waste pipe. The reagent storage device includes a bottle body, a first cover body and a control valve; a first body is connected with an opening of the bottle body in a sealing mode, a first filter is arranged in the first body, and the control valve is arranged in the first body and on the connection path of an opening of the first filter and the opening of the bottle body and is opened when air pressure in the bottle body needs to be supplemented. A second cover body includes a second body and a second filter, the second body is connected with an opening of a waste liquid tank in a sealing mode, and the second filter is arranged in the second body; the control valve is opened when air pressure in the bottle body needs to be supplemented, then outside air enters the bottle body, and the smoothness of solvent delivery in the bottle body is improved. Moreover, the second body of the second cover body of the waste liquid collecting device is connected with the waste liquid tank in a sealing mode, the second filter is arranged on the second body, and therefore the organic volatile harmful gases in the waste liquid tank are filtered and discharged.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a chemical detection system. Background technique [0002] With the continuous innovation and development of science and technology, more and more laboratories are used for chemical technology research and development experiments. Usually, when conducting a chemical experiment, it is necessary to extract the reagent from the reagent bottle to the detector, and after the detection and experiment, the waste liquid output by the detector is discharged into the waste liquid bucket. At present, the method of adding chemical reagents in chemical experiments is mainly to use a suction pipe to pump reagents for addition. During the operation, the extracted organic solvent is usually a liquid with high concentration and strong volatility. During the extraction process, the organic solvent volatilizes harmful gas from the reagent bottle and releases it into the air, ...

Problems solved by technology

[0004] Based on this, it is necessary to provide a chemical detection system that prevents the release of organic volatile substances into the air in view of the problem that the traditional chemical detection system is easy to release organic harmful gases into the indoor air of the laboratory and affect the physical and mental health of the experimenters.
