A comprehensive testing device and testing method for smoke exhaust performance of a smoke exhaust system

Abstract

The present application relates to a kind of smoke exhaust system smoke exhaust performance comprehensive testing device and testing method, solve the single parameter of the present evaluation mechanical smoke exhaust system smoke exhaust performance and the lower reliability of evaluation result, and the technical problem of the lack of quantitative evaluation method for the smoke exhaust capacity of smoke exhaust system today.The device of the present application includes building interior smoke exhaust duct, smoke exhaust fan on smoke duct, fire simulation mechanism corresponding to the inlet of building and smoke exhaust duct is arranged in building, smoke test mechanism is connected with smoke exhaust duct in building.The present application is by measuring the temperature of smoke in smoke exhaust duct, smoke exhaust air volume, the concentration information of each component in exhaust smoke and the change of air temperature and humidity around fire to comprehensively evaluate the smoke exhaust performance of smoke exhaust system, improve the reliability of the judgment of the smoke exhaust performance of smoke exhaust system;The device and method of the present application convert the smoke exhaust performance of smoke exhaust system into measurable values such as smoke exhaust temperature and smoke exhaust air volume, which is beneficial to the evaluation of the smoke exhaust performance of smoke exhaust system.
