Description
[technical field]
The utility model relates to fire fighting device technical field, specifically ductwork type water mists device.
[background technology]
In big-and-middle-sized industrial and mining enterprises, factory building and civil high storey, multi-story structure, adopt water fire-fighting system to be absolutely necessary, and in water fire fighting system except indispensable fire hydrant systems, the current automatic sprinkler system that stamps out a fire is widely used.Fine water mist fire-extinguishing system is a kind of special fire extinguishing system in automatic sprinkler system, to many conditional application scenarios, have potential advantage, particularly supply water in restriction or benefit from the special place controlled with water, his advantage also shows alternative extinction using gas and miscellaneous agent simultaneously.In extinguishing effect, construction costs, environmental protection, secondary disaster loss etc., Integrated comparative is better than the fire extinguishing systems such as traditional gas, Water spray and water spray.
Water mists is under shower nozzle minimal design pressure; 1000 microns are no more than with the water droplet diameter that the thickest position of spraying in shower nozzle 1 meter of plane is calculated; its surface area and density higher; run into rapid vaporization after flame high temperature; inflatable more than 1700 times of volume, makes the oxygen concentration of protection zone greatly reduce, the large calorimetric of simultaneously stability and lowering the temperature; play oxygen barrier or radiation-inhibiting heat, to reach control fire, to press down the object of fire and fire extinguishing.
[summary of the invention]
The purpose of this utility model is to overcome the not good technical barrier of existing fine spray extinguisher extinguishing effect, designs a kind of ductwork type water mists device that effectively can expand fire extinguishing scope, ensure comprehensive covering.
To achieve these goals, a kind of ductwork type water mists device is provided, comprise tank body, gas production charge column, conduit and some nozzles, extinguishing chemical is provided with in tank body, tank body is provided with some powder column cylinders, tank body lower part is provided with conduit and is connected with some nozzles, conduit is provided with valve, described nozzle is parallel-connection structure, on nozzle, cover has kuppe, described kuppe comprises rotating vane and water conservancy diversion shell, fixed axis is provided with in the middle part of water conservancy diversion shell, locating hole is provided with in the middle part of rotating vane, rotating vane is set on fixed axis by locating hole, by air-flow driven rotary blade rotary.
The outer ring of described water conservancy diversion shell offers the arc line shaped spray-hole of some concentric shafts arrangement, and the equidistant arrangement of arc line shaped spray-hole, the inner ring of water conservancy diversion shell is provided with some circular jetting perforations, and the lateral wall of water conservancy diversion shell has along the equally distributed spray-hole of sidewall.
Described rotating vane is provided with some blades, and the angle of blade and plane is 40 degree ~ 120 degree.
Compared with the existing technology, its advantage is the utility model: adopt pure water as extinguishing chemical, to people, environment, protected equipment fanout free region, mist is fine and closely woven, and cooling evenly, to high-temperature component without distortion, damage, is environment-friendly type fire extinguishing system; Water consumption is few, and in identical attack time, injection flow rate is only the 10%-20% of water spray; Water mists can effectively absorb and reduce the solid suspended particle concentration in the flue gas of fire zone, improve visibility, reduce soot to the damage of human body, nozzle is provided with coaxial kuppe, the rotating vane that is provided with of kuppe inside effectively can split air-flow, make the spraying of ejection evenly, water conservancy diversion shell uses mode of grooving, evenly slot at lower surface and side, what expand air-flow fills the air scope, effectively raises extinguishing effect.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1
With reference to figure 1, this device comprises tank body, gas production charge column, conduit and some nozzles, extinguishing chemical is provided with in tank body, tank body is provided with some powder column cylinders, tank body lower part is provided with conduit and is connected with some nozzles, conduit is provided with valve, nozzle is parallel-connection structure, on nozzle, cover has kuppe, kuppe comprises rotating vane and water conservancy diversion shell, fixed axis is provided with in the middle part of water conservancy diversion shell, locating hole is provided with in the middle part of rotating vane, rotating vane is set on fixed axis by locating hole, by air-flow driven rotary blade rotary, rotating vane is provided with some blades, the angle of blade and plane is 40 degree ~ 120 degree.
Water conservancy diversion shell as shown in Figures 2 and 3, the outer ring of water conservancy diversion shell offers the arc line shaped spray-hole of some concentric shafts arrangement, the equidistant arrangement of arc line shaped spray-hole, the inner ring of water conservancy diversion shell is provided with some circular jetting perforations, and the lateral wall of water conservancy diversion shell has along the equally distributed spray-hole of sidewall.Effective side direction can being carried out to side zone of protection and spray protection while bottom spray, making water smoke, when spraying, short distance form total flooding disperse rapidly.
When a fire, along with the rising of indoor temperature, start water mists device, water in tank is promoted by the Compressed Gas in gas production charge column, water divides to each nozzle by conduit, and water is dripped by shower nozzle formation water mists puts out a fire, and particle diameter is less, droplet surface is long-pending larger, heat-absorbing action and efficiency higher.Fine liquid particles is easy to vaporization after being heated, and in gas, liquid status change procedure, absorb a large amount of heats from combustible substance surface or conflagration area, after material surface temperature declines rapidly, thermal decomposition can be made to interrupt, burning stops immediately.
