Flue gas decontamination device

Abstract

The invention discloses a flue gas decontamination device which comprises a cart, a smoke suction device, a CO filtering device, a particulate matter filtering device, a centrifugal fan and a flue gas cooling device, and the CO filtering device, the particulate matter filtering device, the centrifugal fan and the flue gas cooling device are fixed to the cart. The CO filtering device, the particulate matter filtering device, the centrifugal fan and the smoke cooling device are sequentially connected, and the input end of the CO filtering device is connected with the smoke sucking device; the flue gas cooling device comprises a water tank, a spraying mechanism and a spraying box. The device has the advantages that rapid smoke abatement and cooling of a fire scene can be achieved, visibility is improved, toxic gas is eliminated, rapid evacuation of organized personnel and rescue are facilitated, and the personnel are prevented from being hurt by smoke.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a flue gas scrubbing device. Background technique [0002] Small airtight fires such as laboratories, KTVs, and chess and card rooms have the characteristics of fast diffusion, high risk of deflagration, and high mortality. At present, the fire-fighting and smoke-exhausting equipment for such small confined spaces mainly includes automatic sprinkler fire-extinguishing systems and fire-fighting and smoke-exhausting systems. The fire-fighting and smoke-exhaust system sets the smoke-exhaust temperature at 280 degrees Celsius because of the consideration of the channeling fire, so it is not possible to carry out smoke-exhaust for higher flue-gas temperatures; the automatic sprinkler fire-extinguishing system can achieve cooling and fire-extinguishing, but it cannot effectively control the fire smoke. Insoluble toxic gases such as CO cannot be removed without the ability to r...

AI Technical Summary

Problems solved by technology

The fire-fighting and smoke-exhausting system sets the exhaust gas temperature at 280 degrees Celsius in consideration of fire escape, so it cannot carry out smoke exhaust for higher flue gas temperatures; the automatic sprinkler system can achieve cooling and fire extinguishing, but it cannot effectively control the fire smoke Insoluble toxic gases such as CO cannot be removed. Not only is the visibility low, it is not conducive to the rapid evacuation of personnel and the organization of rescue, but the toxic gases in the smoke will also cause harm to personnel.

For example, the Chinese Utility Model Patent Publication No. CN200920144893.1 discloses a fine water mist fire-fighting robot device with a remote fire-fighting system, but this device is also unable to effectively treat fire smoke and remove insoluble toxic substances such as CO. gas, can cause injury to persons
