Abstract

The invention discloses a fire engineering smoke exhaust and ventilation system. The fire engineering smoke exhaust and ventilation system comprises a structure body, the structure body comprises a building of a multi-layer structure, an air supply device is arranged on one side of the building, and an air draft device is arranged on the other side of the building; each floor of the building is provided with a smoke sensor; the air supply device comprises an induced draft fan, a main air supply pipe is arranged on one side of the induced draft fan, and a plurality of sets of branch air supply pipes are arranged on one side of the main air supply pipe; the air draft device comprises a smoke exhaust channel, and a plurality of sets of smoke exhaust pipelines are arranged on one side of the smoke exhaust channel; and a dustproof device is arranged at the top of the smoke exhaust channel. By arranging the air supply device and the air draft device, when a fire occurs in the building, air containing dense smoke in the building is pumped out through the air draft device, meanwhile, clean fresh air is conveyed into the building through the air supply device, so that the smoke concentration of a fire scene is reduced, more survival opportunities are provided for escapers and rescuers, and life and property safety is facilitated.

Description

technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a smoke exhaust ventilation system for fire-fighting engineering. Background technique [0002] Fire protection engineering is an important part of modern architectural design. Every year, the loss of people's lives and property due to building fires is innumerable, so it is particularly important to prevent fires. Severe fires will not only cause a large amount of property loss, but also cause a large number of casualties, so when building construction and building facility layout, fire emergency measures are usually set up. When a fire occurs, a large amount of smoke and dust will be produced. The smoke and dust usually contain a large amount of carbon monoxide, carbon dioxide and other gases that are harmful to the human body. It has been shown that smoke is the chief culprit of death in building fires. Most of the people who died in the fire were suffocated ...
