Abstract

The invention discloses a smoke exhaust emission device and method for a full-smoke exposure experiment. The smoke exhaust emission device is characterized by comprising a sidestream smoke emission connection pipe, a diluted smoke exhaust emission connection pipe and a converged smoke exhaust discharging pipe, all of which are connected through a tee joint; the pipe orifice end of the sidestream smoke emission connection pipe is communicated with a smoking machine sidestream smoke collection hood through a smoke discharging pipe, and a regulating valve is arranged in a pipe cavity of the sidestream smoke emission connection pipe; a regulating valve is arranged in a pipe cavity of the diluted smoke exhaust emission connection pipe, and an air pressure balancing port is formed in the pipe orifice end of the diluted smoke exhaust emission connection pipe in a bifurcated mode; a smoke filtering membrane is installed in a pipe orifice of the converged smoke exhaust discharging pipe. Through the emission device, redundant smoke generated in the experiment can be discharged in real time, it is guaranteed that air in a laboratory is clean without pollution, meanwhile, health and safety of experiment operating personnel are ensured, and the full-smoke exposure experiment can be carried out smoothly.

Description

technical field [0001] The invention relates to the field of external toxicological evaluation of cigarette smoke, in particular to a device and method for exhausting smoke and exhaust gas during a cigarette smoke full-smog exposure experiment. Background technique [0002] The full-smoke exposure experiment of cigarette smoke has just started. At present, the existing smoking machines and smoke exposure systems used for the full-smoke exposure experiment do not have matching exhaust devices for exhausting smoke outside the laboratory. When conducting the full smoke exposure experiment, the cigarette smoke that does not enter the exposure chamber is directly discharged into the laboratory, which affects the indoor air quality. [0003] During the full-smoke exposure experiment, the sidestream smoke generated when the smoking machine smokes cigarettes needs to be discharged outside the laboratory; at the same time, the mainstream smoke generated is diluted by the smoke dilute...
