Abstract
Description
Technical Field
[0001] The utility model relates to the field of fire fighting equipment, in particular to a smoke exhaust device for fire fighting. Background Art
[0002] A lot of smoke is usually produced during a fire. The so-called smoke is a mixture of gaseous and solid substances and air that contains a lot of heat and is generated by the thermal decomposition of substances during the combustion reaction. Since objects are decomposed by heat during a fire, they react and burn rapidly with oxygen in the air to produce various products, and may also produce substances such as carbon monoxide and organic acids. 60% to 80% of deaths in fires are related to the smoke produced during the fire. Smoke not only hinders the escape of escapees, causing them to suffocate due to lack of oxygen, but also hinders firefighters from entering the fire scene to put out the fire, so smoke exhaust work is particularly important when a fire occurs.
[0003] A Chinese patent discloses a fire engineering smoke exhaust device, and its patent number is CN219572170U. In the patent, a fire engineering smoke exhaust device includes a flue; a cross mounting frame is fixed on the inner wall of the flue, a motor is mounted on one end of the cross mounting frame, and a smoke exhaust fan that movably penetrates the cross mounting frame is fixed on the output end of the motor; a baffle is hinged at one end of the flue; a mounting groove is provided at the other end of the flue, and a dust filter plate is provided in the mounting groove. The surface area of the baffle in a fire engineering smoke exhaust device is large, so that the smoke exhaust fan can completely push the baffle to separate from the flue, thereby improving the smoke exhaust efficiency of the flue, and the overall practicality is high. Under the action of the dust filter plate, dust in the smoke entering the flue can be filtered to prevent dust from entering the flue and preventing dust from affecting the working efficiency and service life of the motor, thereby further improving the smoke exhaust efficiency of the flue.
[0004] The above-mentioned published patents have the following disadvantages:
[0005] (1) In the process of using technology to exhaust smoke from the fire point in the prior art, since the smoke spreads inside the entire space, the smoke exhaust work in one direction will limit the working efficiency of the device and affect the subsequent firefighting work.
[0006] (2) Since the internal temperature of the smoke generated by the fire is very high, the high-temperature smoke enters the inside of the smoke exhaust device, causing the device to be in a high-temperature state for a long time, causing the device to be in a high-temperature state during use, thus affecting the service life of the device.
[0007] (3) The existing technology can filter the dust generated by burning objects, but cannot filter harmful substances such as free carbon and dry distillation particles in the smoke, resulting in the harmful substances being inhaled by firefighters, causing damage to their health.
