Smoke exposure experimental device with condensing box

Abstract

The invention discloses a smoke exposure experimental device with a condensing box, comprising a closed combustion cabinet, a condensing box, an exposure experimental box, an air duct and a pipeline. The combustion cabinet, the condensing box, the exposure experimental box and the air duct are sequentially and annularly connected through the pipeline, the condensing box is internally provided with a condenser pipe, the exposure experimental box comprises a box body and a sealing cover, an annular groove is arranged at the top of the box body and contains liquid, a sealing cover covers on the annular groove, an annular vertical wall on the sealing cover is embedded in the liquid in the annular groove, and the air duct is internally provided with an adjustable power fan. In the smoke exposure experimental device, the condensing box is arranged between the combustion cabinet and the exposure experimental box and communicated with the combustion cabinet and the exposure experimental box through multiple groups of coiled pipes, and in an experiment, high-temperature smoke passes by the condenser pipe in the condensing box and can be cooled. Accordingly, the smoke exposure experimental simulation device can avoid burning on an experimental object by the high-temperature smoke in the experiment to further influence the experimental objectivity.

Description

technical field [0001] The present application relates to the field of biomedical poisoning equipment, in particular to a smoke poisoning experimental device with a condensation box. Background technique [0002] In recent years, with the rapid development of social economy, the living environment and life style of human beings have also undergone tremendous changes. At the same time, the incidence of fires is also rising, seriously threatening people's survival and health. [0003] According to the statistics of the global fire survey by the International Fire Protection Technical Committee, in recent years, 6 to 7 million fires have occurred in the world every year, and about 60,000 to 70,000 people have died in fires; The fourth place in the world. A large number of studies have shown that 85% of the victims in the fire died from the inhalation of toxic fumes rather than direct burns. The research on fire burns has been paid attention to by people very early, and remar...

Problems solved by technology

The reason is that in addition to changing smoke conditions, various smoke components, and complex damage mechanisms, the condition control of smoke generation and poisoning devices is also a primary technical bottleneck.

[0004] Through the research on the prior art, the applicant found that the existing smoke generating and poisoning device only considered the control of the smoke generation when conducting the poisoning experiment, but ignored the possibility that the high temperature carried by the smoke might cause burns to the test subjects Bias, so the objectivity of the experimental data of smog exposure cannot be guaranteed
