A smoke exhaust device for fire engineering and using method thereof

Abstract

The invention discloses a smoke exhaust device for fire-fighting engineering and its use method, which belongs to the technical field of fire-fighting equipment. A rotating mechanism is fixedly connected to the supporting frame, and the top end and the bottom end of the rotating mechanism are respectively fixedly connected to the lower surface of the transmission fan blade and the upper surface of the first gear. The smoke exhaust device for fire engineering and its use method, by setting the transmission fan blade, the fourth gear and the exhaust fan blade, the smoke exhaust device has the function of discharging smoke when a fire occurs, and when the smoke is burning, due to the dense The high heat inside the smoke makes the smoke float upwards. The smoke exhaust device can effectively discharge the dense smoke, making it difficult for people at the fire scene to inhale more smoke into the body, reducing the smoke entering the human respiratory tract and causing harm to the human body. The possibility of effectively guaranteeing people's safety.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, in particular to a smoke exhaust device for fire-fighting engineering and a method for using the same. Background technique [0002] The smoke prevention and exhaust system is composed of air supply and exhaust pipes, pipe wells, fire dampers, door switch equipment, exhaust fans and other equipment. The smoke exhaust volume of the mechanical smoke exhaust system is directly related to the smoke prevention zone. Facilities should be divided into smoke prevention facilities with mechanical pressurized air supply and natural smoke exhaust facilities that can open the outer windows. At present, due to the rapid development of my country's economy, there are more and more high-rise buildings. When a fire occurs, the probability of high-level personnel escaping is low. And statistics show that when a fire breaks out, very few people are directly burned to death, but the thick smoke when t...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a smoke exhaust device for fire-fighting engineering and its use method, which solves the problem that a large amount of oxygen will be consumed and a large amount of toxic smoke and heat will be discharged when the flame burns. However, the existing building fire-fighting equipment is only equipped with sprinkler equipment, and the treatment efficiency for dense smoke is low, so that in the event of a fire, the probability of people in the building escaping is low, and it is difficult to guarantee people's safety.
