Abstract

The invention discloses a gas-solid-liquid multi-hazard-factor coupled catastrophe environment simulation system. The environment simulation system comprises a gas-solid-liquid hazard factor generation system, a multi-hazard-factor coupled catastrophe environment simulation system and a hazard factor selection and concentration regulation and control system. The environment simulation system of the invention can simulate a human body harm condition in a catastrophe environment under the independent or coupled effect of various hazard factors with different concentrations; and the system can also be used for evaluating the performance of individual protection equipment and carrying out pathological toxicology basic experiments of various hazard factors; the environment simulation system isof great significance to promotion of foundation and application research in the fields of occupational health, public safety, emergency rescue and the like.

Description

technical field [0001] The invention relates to the technical fields of occupational health, public safety, and emergency rescue, and in particular to a gas-solid-liquid multi-hazard factor coupling catastrophe environment simulation system. Background technique [0002] The air on which human beings depend is composed of nitrogen, oxygen, rare gases, carbon dioxide and other substances (such as water vapor, impurities, etc.). With social progress and industrial development, air pollution is gradually increasing, and the concentration of various toxic and harmful substances is increasing, endangering public safety. In 2002, the General Administration of Quality Supervision, Inspection and Quarantine issued the "GBT18883-2002-Indoor Air Quality Standard", which clearly stipulates that CO / CO in indoor air 2 / H 2 S / SO 2 / NO 2 / Concentration limits of toxic and harmful gases such as formaldehyde. Even so, there are still hazardous gas exceeding the standard in some special ...
