Frame manufacture becomes to have forward part and the lateral parts that is set out by the carriage hydraulic giant.
Framework is made along the periphery that is set out by the carriage hydraulic giant, where necessary, comprises bottom surface and ceiling.
Essence of the present invention is that the sputter jet of liquid is made of the single stream of liquid droplets that flies to escape, and has adopted special sprayer for obtaining the single drop that flies to escape---nozzle [4].The jetting stream of liquid is characterized by following feature, promptly dispersivity, drop size, they are along distribution, the taper angle of jet, range, pressure head and the flow of liquid before nozzle of jet area.In practice, the injection method that the most widely adopts is centrifugal process, pneumatic process and Mechanical Method.
Along with the raising of the pressure head before the nozzle, the diameter of drop reduces.The pressure that fire pump is set up is 1.2MPa, and in practice, the average diameter of drop is 400-500 μ m in the nozzle hydraulic giant.In high-pressure installation, the pressure reduction in the nozzle can reach 15MPa, and at this moment, the diameter of drop is 5-10 μ m.By the drop of nozzle sputter, both when flying hither plane, when these planes of contact, absorptive thermal radiation began gasification, and very big at the kinetic energy of considering drop again, be able in the space, and the outside reflex time repeatedly from the surface, this effect is strengthened.The selection of surface configuration and their materials, for example shaping surface is reticulated, the selection of the diameter of their feature, size of mesh opening, silk and material etc. is carried out in the following manner, promptly be sidelong from operator one on the inner surface of putting at least, because surface tension, should form the film of the liquid that adopts, the denseness of liquid can keep, and vaporescence during film absorption heat energy and film itself is because the dynamic equilibrium between the constantly additional process that the drop of sputter liquid and its collision form.
Like this, we can say, basically form continuous steam drop air dielectric in the space between the surface.Because radiation infrared, light and convection current that fire produces, part be from the surface reflection, part from network, from the film set up, reflect from steam drop air dielectric; The steam drop air dielectric that part is established absorbs, and is pulled away in the thermal-radiating direction of motion perpendicular to fire.
Obviously, the reflection that can flow of input and the actual similar symbiosis of absorption process have exclusive characteristic: the validity of the thermal protective performance of this device increases with the growth of importing heat flow value.
Liquid is injected into trickle disperse state by high-tension apparatus, and its liquid-drop diameter can be compared with the thermal-radiating wavelength of fire (about 1.5-7 μ m), and this also will promote the increase of similar device thermal protective performance validity.At this moment, by laws of geometrical optics, the best trickle dispersivity of drop will make the heat radiation dissipation process strengthen several times [5].
Cooling agent inputs in two spaces between the protection coating, but as protection coating applied metal silk fabrics, fiberglass fabric or other material, the necessity of regulating amount of coolant-M depends primarily on heat flow value W, and heat flow value W is in actual fire---by 0 to 200-250KW/m
2At this moment, when the value of W also at W ≌ 3-4KW/m

Let us is watched a supposed situation, wherein, sends into the hot-fluid W of screen

2When setting up the water droplet curtain, when the average diameter of drop be reduced to can with the thermal radiation wavelength (magnitude of 5-10 μ m) of fire when comparing, W
0Weakening reach maximum [6].
At this moment, in experiment, W
0Weakening can reach 4-6 doubly.Simultaneously, because the speed magnitude of water droplet is 10m/s, therefore, vaporescence is not obviously effect in heat absorption.
When using the netted curtain of one side of cooling water [7], W
0Weaken and also reach 3-4 doubly.
During the netted curtain arranged, the multipath reflection of water droplet by the inner surface of two veils takes place using that there is spacing in the two sides therebetween.At this moment liquid drop speed slows down, and drop itself and net collision split into trickleer drop, and the part water quality of drop had both adhered on the surface of twine, and the grid that can adhere to net again is (relevant with the size of grid) originally on one's body, the formation film.These processes both had been consumed in the heating of the drop of water and film the heat energy of input greatly, were consumed in greatly in their vaporization again.Simultaneously, be directed at heat radiation and convective heat flow-W by these phenomenons that have two letter protection coating decisions
1Dissipation and the enhancing of reflection process, both from netting itself, again from water film formed thereon, also the steam drop air dielectric the space reflected between the net from resulting from for heat radiation and convective heat flow.
Also should be mentioned that the interaction phenomenon that is observed visually light and infra-red radiation and convective heat flow and steam drop air dielectric in the experiment, steam drop air dielectric is formed at the close vicinity of the protection offscreen surface of feeding hot-fluid side.
When the droplets impact its protection network, drop splits into more tiny drop, and its part is sputtered onto in the scope outside the Cyberspace.To being arranged in the situation of relative fire side for positive net, the water of skipping the globule of trickle disperse of net and vaporization forms the thin layer of the observable steam drop of naked eyes air dielectric, and it is close on the outer surface of positive veil of relative fire side.
Be incident on the outer surface of positive veil and the interaction of the hot gas convection current of reflection from it and this steam drop air dielectric outside thin layer, be directed at the instability pulsation of macroscopic this medium, and heat energy along veil outer surface just at W
0" dropping down stream " of the incident vector direction of stream.
The hot-fluid weakening method of being advised like this, is different from the method for previously known in principle.When absorbing and vaporescence when having begun substantial role in hot-fluid weakens, it has just changed situation qualitatively.Shown in calculating cited above, have the ability on these procedural theories just even the fire damage protection question in the hugest fire is solved fully.Be to be noted that in described method value W

2With value W
0Increase and increase, also, the self-regulation with incident hot-fluid weakens.Simultaneously, because energy absorption and vaporescence influence value W substantially herein
0The weakening degree.But described invention might make this process become manual adjustment.This adjusting can manual adjustments or is regulated automatically, and its method is by computer programs, and information is by in the thermal radiation sensor input computer that is arranged on the protected target; Perhaps manually regulate.In experiment, this produces by connecting (cut-out) portion nozzle, and water inputs in the space between net by nozzle, and perhaps the pressure that is transfused to water or cooling agent by adjusting produces.This is able at acceptable value W
0Under the condition that weakens, save greatly and set up and the spent water yield of maintenance steam drop air dielectric.
The absorption coefficient of the absorption projectile energy of steam drop air dielectric in the liquid of input, adds coloring agent and also helps to increase the validity of the thermal protective performance of described device, because at this moment will improve [8].
Injecting-unit is made into the nozzle system that is arranged on the framework by particular form is guaranteed the even distribution of drop in the space that is formed by the surface, under special circumstances, these surfaces are to have the net that is fastened to the framework both sides with gap.
With the injury that the protecting screen screen making becomes the semi-ring shape to be able to from the front and fence operation person is not subjected to the fire hazard factor from the side.Screen can be made into along periphery and in the protective cover shape at top when extinguishing extrahazardous target, thereby from front, side, the back side and come fence operation person above oneself.Total is arranged on the platform of belt wheel, total can be moved easily; And structure is provided with drive apparatus, then make structure have mobility.
