Description

Automatic smoke exhaust system for fire engineering

Technical Field

The utility model relates to a fire engineering technical field, more specifically say, it relates to an automatic system of discharging fume for fire engineering.

Background

With the increasing shortage of land resources, people are gradually moved into high-rise residences to live in, and more than ten or even hundreds of residents live in one high-rise residence. Due to the high concentration of people, the loss caused when a fire breaks out in a high-rise residence is huge. According to fire data, the smoke is the chief culprit of death of people in building fires, and at present, the smoke exhaust effect is achieved by manually opening a window of a fire stair when a fire occurs, however, once a fire occurs, people generally can escape from the window in a timely manner, and few people waste the escape time to open the window for smoke exhaust.

To the above-mentioned problem, chinese patent that publication number is CN209569860U discloses a fire control system of discharging fume, when the conflagration breaing out, the air exhauster automatic start is taken out dense smoke outdoors, prevents that dense smoke from being full of the corridor, provides more escape time for the crowd of fleing for one's life, simultaneously, in order to prevent to discharge fume to pile up cigarette ash after the pipe uses for a long time, influences the smoke exhaust effect of discharging fume the pipe, through setting up material such as dust in the filter screen filtering dense smoke.

But along with continuously discharging the dense smoke in the corridor through the smoke exhaust pipe, the cigarette ash adhered on the filter screen can be more and the filter screen gradually causes the jam, can weaken the smoke exhaust effect of the smoke exhaust pipe gradually.

A new solution is therefore proposed to solve this problem.
