A window type atomized water curtain fire sprinkler

Abstract

The invention discloses a window type atomization water curtain fire-fighting spray head. The window type atomization water curtain fire-fighting spray head comprises a spray head main body, a rotarybody and a support table. The support table is a circle of protrusion located on the lower portion at the inner side of a spray head body. The rotary body comprises two coaxial cylindrical bodies, wherein the two coaxial cylindrical bodies are closely fixed together and are different in bottom face radius. A rotary body thin portion is put on the support table in a manner that the rotary body thinportion faces downwards. A rotary body thick portion is slightly smaller than the inner diameter of the spray head body. A cavity is formed between the thin portion and the inner wall of the spray head body. Multiple curve-shaped external flow grooves are formed in the outer side of the rotary body. The bottom of the spray head body is provided with a vortex cavity. The side face of the spray head body is provided with a water outlet notch. When the window type atomization water curtain fire-fighting spray head is started, water flow enters the spray head body through a fire fighting pipe; the flowing direction is changed through the external flow grooves; then, the water flow enters the cavity formed between the rotary body thin portion and the inner wall of the spray head body for atomization; and atomization particles enter the vortex cavity, so that a vortex is formed, and furthermore, the water flow flows out of the water outlet notch and is jetted to the surface of glass. By means of the window type atomization water curtain fire-fighting spray head, the water consumption for fire fighting can be reduced; meanwhile, the fire fighting water drainage amount generated after a disaster is reduced; a formed curtain is stable; in addition, by means of the atomization particles, the environmental temperature can be lowered better; and the effect that the glass is protected is achieved.

Description

technical field [0001] The window-type atomized water curtain fire sprinkler belongs to the field of fire engineering, and particularly relates to the fire-blocking protection technology for floor-to-ceiling glass in the event of fire in a large shopping mall. Background technique [0002] In the past 20 years, various large-scale comprehensive commercial buildings have emerged in large and medium-sized cities in my country. These buildings include restaurants, cinemas, playgrounds, beauty salons, swimming pools, exhibition halls and other entertainment and leisure places, collecting clothing, food, entertainment, etc. The integration of purposes makes a single store group develop into a multi-functional business, service, entertainment, and social center, making people's lives more convenient. In order to make shopping and leisure places more aesthetically pleasing and comfortable, such buildings often use glass instead of non-combustible walls as fire protection partitions....

AI Technical Summary

Problems solved by technology

The traditional water curtain can play the role of fire prevention, cooling and dilution and smoke isolation in a fire, but there are also disadvantages such as unsatisfactory fire prevention and smoke isolation effects and large water consumption, especially when used in large shopping malls. The goods in the shopping mall were greatly damaged, resulting in water damage. At the same time, drainage was also difficult, and it took a long time to resume operations after the fire

Ordinary window-type nozzles use the form of a splash plate to distribute water, and the water curtain formed is unevenly distributed, and there is a large flow loss, and the curtain forming effect is poor.
