Description

Smoke-proof purifying system for high-rise building

Technical Field

The utility model relates to a high-rise building smoke protection technical field, concretely relates to high-rise building's smoke protection clean system.

Background

When a fire disaster occurs in a high-rise building, due to the reasons of fast fire spread, much generated smoke, high smoke toxicity, fast smoke diffusion speed and the like, the fire fighting and extinguishing difficulty is high, personnel evacuation is difficult, and casualties and property loss are severe once the fire disaster occurs, and statistics shows that after the fire disaster occurs, the casualties with the proportion of more than about 70 percent are caused by smoke suffocation, so that the prevention of the smoke diffusion in the high-rise building is an important subject for the fire fighting of the high-rise building.

The fire-fighting requirement of high-rise buildings requires longer evacuation time, in order to ensure the smoothness of an evacuation channel, a smoke-proof system is mostly arranged in a front room of a staircase to prevent smoke from entering the evacuation channel, and the smoke-proof modes of the front room commonly adopted at present comprise the following three modes: the first is the mechanical smoke exhausting and natural air intake mode of the front chamber; the second is the pressurizing of the front chamber and the smoke exhausting mode of the corridor; the third is the mechanical air supply and exhaust mode in the front chamber. The first mode and the third mode are similar, smoke is allowed to enter the front chamber, and part of smoke inevitably enters a staircase along with evacuated people, so that the evacuation and the fighting of the people are not facilitated, and the evacuation is influenced; the second mode is when the conflagration, often because the opening of front chamber door for positive pressure is hardly guaranteed to the antechamber, still can make a large amount of fresh air flow into the floor, encourages the intensity of a fire on the contrary, and the corridor is discharged fume and is efficient also not high. Therefore, it is an objective need to develop a smoke-proof purification system for high-rise buildings, which has high smoke-discharging efficiency, can effectively prevent smoke from diffusing and can ensure the smooth evacuation channel.
