Description

Inner walkway fire-fighting smoke-discharging system

Technical Field

The utility model belongs to the technical field of the fire control is discharged fume, especially relate to an interior aisle fire control system of discharging fume.

Background

With the execution of technical Standard for Smoke prevention and Smoke evacuation System for buildings GB51251-2017 (hereinafter, the technical Standard is called as the Specification), the lengths of public buildings, particularly hotels and offices are very longThe design of long inner walkways for fire protection and smoke evacuation has become a common problem encountered in the industry. Maximum allowed smoke discharge amount of single smoke discharge port due to specification 4.6.14 (Vmax =4.16 x gamma x d)_B ^5/2×（△T/T0）^1/2) Is limited, and the maximum allowable smoke discharge amount and d_B(thickness of smoke layer below lowest point of smoke outlet) is directly related. Because the number of the pipelines of the inner walkways is generally large and the net height of the inner walkways is not high, the thickness of the smoke layer of the inner walkways is very small, and the number of smoke outlets is increased exponentially. And the increase of exhaust port quantity leads to the flue gas tuber pipe again and must install the horizontal pipe in the inner walkways furred ceiling, and the exhaust pipe must set up antidetonation support in addition, and this further has depressed indoor net height, leads to the exhaust port quantity more again in turn. In addition, fire-fighting equipment facilities such as a smoke outlet, a fire damper and the like require 3C authentication, and a remote control multi-blade smoke outlet with a 280 ℃ function does not have 3C authentication, so that the fire damper, the smoke outlet and the smoke outlet cannot be used, and can only be replaced by the fire damper, the smoke outlet and the smoke outlet, and due to the addition of the fire damper and the smoke outlet, a horizontal air pipe is required to be arranged for spatial installation, and in addition, a special maintenance port is required to be arranged on a ceiling, so that the ceiling shape is influenced.
