Abstract
Description
The present invention relates to an intelligent multi-agent compressed air sprayer, and more particularly, to an intelligent multi-agent compressed air sprayer capable of effectively extinguishing bubbles generated by foaming a foam water- The present invention relates to a fire extinguisher.
Fire extinguishers are provided for early suppression in the event of a fire and are classified into water extinguishers, acid / alkaline extinguishers, fortified liquid extinguishers, halogen compound extinguishers, carbon dioxide extinguishers, powder fire extinguishers, Depending on the release method, it may be divided into a pressure type fire extinguisher and an accumulator type fire extinguisher. Each fire extinguisher is used to match the characteristics of the fire.
The dual foam fire extinguishers are divided into chemical fire extinguishers and mechanical fire extinguishers and are suitable for underground spaces and tunnel fires by eliminating the problems of fire extinguishers (powder, carbon dioxide, halogen compounds) Body, hose and nozzle. Here, the chemical fire extinguisher is now in a state of discontinued production.
A mechanical foam gun is a system in which a foam aqueous solution containing a mixture of digestion water and a foam stock solution (fire extinguishing agent) in the body is discharged to a hose through a discharge pipe connected to a fire extinguisher body by an axial compression method or a pressurizing method using a compressed gas, Air is sucked in from the air intake port provided in the nozzle and mixed with a foam aqueous solution at the tip of the nozzle to form a bubble and then the resulting bubble is applied to the surface of the fire of the combustible, Controlling the fire through the cooling action of water contained in the bubble.
However, since these guns are large in size and have a low specific gravity, the flash range is short and wind blowing phenomenon occurs. Therefore, it is necessary to approach to the flame side in order to extinguish the fire, So that the foam applied on the flame side can be separated by buoyancy and air flow. In addition, there is a problem that the inflow of air according to the outside air condition is uneven, the foaming of the foil is not uniform, the digestion effect is not stable, and the digestion efficiency is low.
In order to solve the problem of such a fire extinguisher, a fire extinguishing system for generating foam using compressed air has been proposed.
FIG. 1 is a view for explaining a foam generating unit for mixing a foam aqueous solution and compressed air in a conventional compressed air fogging plant (Korean Patent No. 10-1130183, smart non-powered automatic foam fogging plant).
In the compressed air foaming system as shown in FIG. 1, a foam generating part for generating foam by mixing a foam aqueous solution and compressed air is indispensably required.
1, the foam generating unit provided in the conventional compressed air spraying apparatus is provided with a connecting
However, the foam generator provided in the conventional compressed air purging apparatus as shown in FIG. 1 uses a spray hole formed in the form of a straight line, a ring, or a coil in the foam aqueous solution flowing along the
When the foam density is low (the size of the foam is large, the number of capsules in the unit space is small), the air resistance is large, so the range of fire is limited and the sticking property to the fire surface is also deteriorated.
Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a method for producing a foam having a high foam density and a uniform size, , And an intelligent multi-agent compressed air foamer capable of increasing foam spreading and adhesion of the foam.
According to another aspect of the present invention, there is provided an intelligent multi-agent compressed air purger comprising: a foam generator for generating foam by mixing compressed air and a foam aqueous solution; Wherein the foam generating unit comprises: a foam aqueous solution inlet path through which a foam aqueous solution is supplied; A compressed air inflow path through which compressed air is supplied; And a primary foaming unit for mixing the foamed aqueous solution and the compressed air, which have entered through the foamed aqueous solution entry path and the compressed air entry path, to form a foam by sparging through the fine holes.
Here, the primary foamed portion may be made of a porous structure or a pore structure filled with particulate matter so that the compressed air and the aqueous foam solution pass through the pores of the porous structure or the pore structure, A uniform size form can be generated.
The foam generating unit may further include a secondary foaming unit and a tertiary foaming unit for increasing the density of the foam sprayed from the primary foaming unit.
In addition, the compressed air inflow path of the foam generator may be connected to a separate compressed air supply unit to supply compressed air.
According to the intelligent multi-agent compressed air purger according to the present invention, the compressed air (or compressed gas) and the foam aqueous solution are made into fine holes through the compressed air injecting part in the form of the pore structure filled with the porous structure or particulate matter and the primary foaming part So that foam of high density can be produced by generating dense and uniformly sized bubbles. The dense foam can reduce the air resistance and increase the radial distance, so that even if the user is not approaching the fire position, the compressed air foil can be sprayed on the fire surface from a distance and the adhesion of the compressed air can be improved The digestion efficiency can be maximized.
In addition, the resulting foam may be passed through the secondary foaming portion, the tertiary foaming portion and the quadratic foaming portion again to further increase the foam density. Thus, The foam density can be maintained.
That is, when the foam density is high, the foam has a dense and uniform size in the unit space. Accordingly, the specific gravity of the foam is high, which is strong against the air resistance and can greatly improve the radiating range when the chemical is discharged. In addition, the dense and uniform size foam has a strong physical property and high adhesion, resulting in an increase in both the vaginal and cooling effects, and the addition of the additive to the foam aqueous solution leads to the effect of the non-adsorption, Very good.
