Embodiment 1

[0036] like figure 1 As shown, the bracket can change the angle, thereby changing the angle of the vertical fire pipe and the ground. When connected to the water source, the device can spray spray continuously to form a fire-proof partition water curtain, which plays the role of fire-proof partition. When the installation angle of the vertical fire-fighting pipeline is changed so that the water mist is sprayed on the building on fire, the temperature of the building on fire can be effectively reduced, and the fire control effect on the building on fire can be realized.

[0037] In order to verify the fire and heat insulation effect of the device, the temperature change and heat radiation change after the device is installed are tested by means of a physical test. A group of mobile fire separation devices are set up outside.

[0038] The vertical fire-fighting pipeline adopts two length specifications, the lengths are 2.2m and 1m respectively, and the vertical pipelines with ...

Embodiment 2

[0050] In this implementation example, change the vertical pipeline to be 60° with the ground, and spray water toward the cultural relic building, and other conditions are the same as in Embodiment 1. The average temperature of the protected side is 20°C lower than that of the unprotected side, the maximum temperature of the protected side is 57°C, and the maximum temperature of the unprotected side is 25°C. The average radiant heat on the protected side is 3.2KW less than the average radiant heat on the unprotected side.

Embodiment 3

[0052] In this implementation example, change the vertical pipeline to be 45° with the ground, and spray water toward the cultural relic building, and other conditions are the same as in Embodiment 1. The average temperature of the protected side is 10°C lower than the average temperature of the unprotected side, the maximum temperature of the protected side is 60°C, and the maximum temperature of the unprotected side is 35°C. The average radiant heat on the protected side is 2.3KW less than the average radiant heat on the unprotected side.

Abstract

The invention discloses a mobile fire compartmentation device for a cultural relic building as well as application and a test method of the mobile fire compartmentation device and belongs to the technical field of fire protection. Multiple long branch pipelines (3) and multiple short branch pipelines (4) are uniformly and fixedly connected to a total fire pipeline (1) in a length direction, are perpendicular to the total fire pipeline (1), are alternately distributed at an interval and are arranged in one plane; each of the upper end part of each long branch pipeline (3) and the upper end partof each short branch pipeline (4) is provided with a nozzle (2); a water spraying direction of each nozzle (2) is consistent to the length directions of the long branch pipelines (3) and the short branch pipelines (4); and the long branch pipelines (3) and the short branch pipelines (4) are all fixed with cylindrical tubes coaxially connected with a pipeline section (6) of the total fire pipeline(1) and a axially perpendicular branch pipe. The mobile fire compartmentation device can be used for fire prevention and extinguishment of the cultural relic building.

Description

technical field [0001] The invention relates to a mobile fireproof separation device for cultural relic buildings, its application and inspection method, and belongs to the technical field of fireproofing. Background technique [0002] The fire separation distance is the minimum distance between a building fire and adjacent buildings under the action of heat radiation, even if there is no protective measure, it will not catch fire. Whether the fire can spread to adjacent buildings, in addition to the distance between buildings, is also restricted by three factors: heat radiation, heat convection and flying fire when a fire breaks out in a building. Under the condition of a certain distance between buildings, the higher the intensity of radiant heat, the greater the possibility that adjacent buildings will be ignited; the faster the convection speed of cold and hot air inside and outside the building on fire, the easier it is to dispose of unburned objects (i.e. flying fire)...
