Fire-fighting auxiliary rescue equipment with function of reducing fire smoke dust

Abstract

The invention relates to fire-fighting auxiliary rescue equipment with the function of reducing fire smoke dust. The fire-fighting auxiliary rescue equipment comprises a hollow pressurizing air duct. An air draft system is arranged in the pressurizing air duct and comprises an explosion-proof motor installed on the inner side of a bucket-shaped air inlet through a triangular motor support, the rotating end of the explosion-proof motor is connected with a rotating shaft, multiple air draft impellers are installed on the rotating shaft, the interior of a square cylinder on the side away from the bucket-shaped air inlet is divided into a closed partition bin and an air channel through a partition plate I, and an air filter block is arranged in the partition bin and can slide out of a filter block opening to enter the air channel. Smoke dust is filtered through the air filter block, the content of smoke dust in air can be reduced, the equipment is small in overall size, control and smoke dust reduction can be achieved in a fire scene in a portable and movable manner, meanwhile, the equipment can be fixed in a corridor, a public space and a space with large personnel density, a needed safe environment is provided for survival of multiple personnel, time is won for rescue, and the survival probability of fire trapped personnel is improved.

Description

technical field [0001] The invention relates to the technical field of fire rescue equipment, in particular to an auxiliary fire rescue equipment capable of reducing fire smoke and dust. Background technique [0002] Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. A fire occurs when all kinds of objects are ignited out of control in space, and a large amount of combustibles are burned to produce toxic and harmful smoke, such as carbon monoxide, carbon dioxide, hydrogen cyanide, sulfur dioxide, nitrogen dioxide, etc. These gases have different effects on the human body. Among them, the most toxic gas is carbon monoxide. According to the investigation and statistics of the National Fire Administration, more than 80% of the people who died in the fire were caused by smoke suffocation, and only some people died in the fire. Fire smoke will cause serious hazards, and its hazards mainly in...

Problems solved by technology

[0003] The main auxiliary equipment of existing fire rescue equipment for fire smoke and dust is mostly protective masks, ventilators and other equipment, but they can only be used by a single person, but in actual use, only a small amount (generally 2~ 3) smoke and dust filter masks, the use is limited, for the vast majority of trapped people, there is a need for a fire-fighting aid that is easy to operate and move, can control and reduce smoke and dust at the fire scene, easy to use, and low in cost rescue equipment
