In a fire, a large amount of smoke is usually generated, which is a mixture of gaseous and solid substances containing a large amount of heat and air, generated by thermal decomposition of the substances during a combustion reaction. Combustible materials such as building materials, furniture, clothes, paper, etc. are decomposed by heat during fire, and then rapidly react with oxygen in the air to burn, and various products are generated, and if the combustible materials are completely burned, the products are few, and generally include carbon dioxide, water, nitrogen dioxide, phosphorus pentoxide, hydrogen halide, etc., and if the combustible materials are not completely burned, carbon monoxide, organic acids, etc. may be generated in addition to the above products. 60% -80% of the death reasons of the dead people in the fire are related to smoke generated in the fire, and the smoke can not only prevent the escape of the escaper and suffocate the escaper in an anoxic way, but also prevent the firefighter from entering the fire scene to fight the fire, so the smoke exhaust work is particularly important in the fire.
Most of existing smoke exhausting equipment is a blower driven by a motor, and the smoke exhausting equipment is limited by a power supply and cannot be applied to a scene with power failure or explosion prevention caused by a fire; on the other hand, the existing smoke exhaust for fire fighting generally adopts an axial flow fan, only the smoke is pumped to the rear end of the fan from the front end of the fan, and the smoke backflow cannot be prevented.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at overcoming the defect among the prior art, provide a fume extractor for fire control for the work of discharging fume is carried out at the conflagration scene, and simple structure does not receive the power restriction, can realize the malleation and blow, negative pressure function of discharging fume.
The utility model discloses a smoke exhaust unit for fire control, including the base, set up in the air duct on the base and install the exhaust fan in the air duct, the exhaust fan includes pneumatic motor and the rotatory flabellum that is used for providing power, be provided with the compressed gas cylinder in the base, the compressed gas cylinder gas outlet passes through the air duct and connects the switching-over valve air inlet, the switching-over valve gas outlet communicates the pneumatic motor air inlet; the wind guide device is characterized by further comprising a wind guide channel which is arranged at the rear end of the wind guide cylinder and can be folded along the longitudinal direction, the wind guide channel comprises a hard annular structure for preventing radial deformation and a soft fireproof material connected with the hard annular structure, and the wind guide channel and the wind guide cylinder are detachably connected.
Further, the base is a tracked vehicle chassis.
Further, the soft fireproof material is flame-retardant rubber cloth.
Furthermore, the edge of the air duct is provided with atomizing nozzles, and the atomizing nozzles are connected with an external water pump through a guide pipe.
Furthermore, the rear end of the air duct is rotatably arranged on the base, the front end of the air duct is rotatably provided with a hydraulic rod, and the other end of the hydraulic rod is rotatably connected with the base.
The utility model has the advantages that: the utility model discloses a smoke exhaust apparatus for fire control adopts pneumatic motor to drive rotating fan blade and discharges fume, utilizes the compressed gas cylinder air feed that sets up in the base, can use under no power and flammable explosive place, has effectively dealt with dense smoke conflagration to fire fights and has played positive effect to fire fighter, and is provided with the wind-guiding passageway, prevents that the flue gas from flowing backward.
