Embodiment Construction

[0050] Please refer to FIG. 1 , which is a schematic diagram of a preferred embodiment of the long-channel fire-fighting system of the present invention. The long passage fire system 100 is applied in a long passage 110, such as a shopping street, or a corridor of an office building, a hospital, or a hotel. The long channel 110 has an air inlet 112 and an air outlet 114 . The long channel fire protection system 100 comprises a first water mist curtain device 120 arranged at the top of the air inlet 112, a second water mist curtain device 130 arranged at the top of the air outlet 114, and arranged between the air inlet 112 and the air outlet 114 At least one third water mist curtain device 140 on the top.

[0051] When there is a fire-fighting accident, start the long passage fire fighting system 100, and the vertical water mist curtain sprayed by the vertical spray nozzle 142 of the third water mist curtain device 140 in the long passage 110 can make the long passage 110 It ...

Abstract

The invention relates to a long channel firefighting system, which is applied in the long channel provided with an air inlet and an air outlet . The invention comprises a first water spray curtain device, a second water spray curtain device, and at least a third water spray curtain device, wherein the first water spray curtain device is arranged at top part of the wind inlet, the second water spray curtain device is arranged at top part of the air outlet , the third water spray curtain device is arranged at top part of the long channel between the air inlet and the air outlet so as to divide the long channel into a plurality of firefighting areas. The purpose of the invention is to prolong escape time when disaster happens, and reduce the influence of thick smoke on persons.

Description

technical field [0001] The invention relates to the field of long-channel fire-fighting systems, in particular to a long-channel fire-fighting system in the form of water mist (watermist). Background technique [0002] In today's society, with the increase of buildings, the importance of fire protection facilities is becoming more and more important. The effects of a fire include heat, thermal radiation and smoke. In a fire scene, the biggest threat to people's escape is not the flame itself, but the by-product of incomplete combustion - toxic smoke. Toxic smoke often contains carbon dioxide, carbon monoxide, hydrocarbon gases and many solid particles. In addition to carbon dioxide, the substances in the part of the toxic smoke are still flammable. When these flammable substances accumulate in a confined space and reach a critical concentration, they can instantly trigger flashover in accordance with the temperature of the fire site and the concentration of oxygen, resulti...
