International Interflam Conference, 8th Proceedings.1999Volumel, Volume 1, 1999, pages 454-456 held in Edinburgh, Scotland in 1999, "Composite Fire Detectors in Simulated Experimental Devices" The article "Evaluating Multi-Sensor Fire Detectors In the FireEmulator/Detector Evaluator" mentions a fire detection simulation experimental device. Since the experimental device is a channel with openings at both ends, the simulated fire smoke will pass through the test section immediately The airflow temperature and temperature rise rate that the simulated flue gas can reach are determined by the maximum heating powe

Abstract

The comprehensive fire detection simulating experiment apparatus includes left passage with valve f1 in its lower left air inlet, valve f3 in its upper left exhaust port and valve f2; lower passage with blower, heater, dust adding port and humidifying port; right passage with standard gas inlet, aerosol inlet, valve f8 and flow collecting hood; solenoid valves f4, f5, f6 and f7 installed in different sites; and tested fire detector with probe inside the upper passage, flow homogenizing board and observing window on the passage wall. The apparatus may operate in open-loop mode or closed-loop mode through controlling the valve f1, f2 and f3. Using the present apparatus can save experiment material, reduce waste gas exhaust pollution, provide excellent analysis condition of simulating fire fume and detect various fire detector performance accurately.

Description

Technical field: [0001] The invention relates to a simulation experiment device for performance detection of a fire detector. Background technique: [0002] The quality of fire detectors directly affects the safety of people's lives and properties. Therefore, it is extremely important to test the performance of fire detectors. There are two ways to detect the performance of detectors: one is to generate fire smoke by actually burning combustibles, so as to detect it; the other is to simulate fire smoke by designing a set of experimental devices, and then detect fire in it. device for performance testing. The latter method is a detection method that has recently emerged in the world. There are still few studies in this area, but because of its unique advantages, it brings great convenience to experimenters or engineers, and has attracted the attention of relevant researchers. . International Interflam Conference, 8th Proceedings.1999Volumel, Volume 1, 1999, pages 454-456 h...
