Description

{Smart multi-agent CAFs foam extinguisher}

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 portion 12 through which a foam aqueous solution flows into one side of a body 11 having a spiral portion 14 formed therein And an air injection nozzle 13 into which compressed air flows at an intermediate point. When the foam aqueous solution flows through the connection part 12, a vortex is formed as the foam aqueous solution moves along the spiral part 14 inside the body 11, and the compressed air flows through the injection port of the air injection nozzle 13 When compressed, the compressed air is mixed with the foam aqueous solution vortex to form a foam (compressed air bubble).

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 spiral portion 14 Since the compressed air bubbles are generated by injecting the compressed air in the simple longitudinal direction, the size of the compressed air bubbles is equalized or the density is increased (the number of bubbles in the unit space is increased) have.

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.

≪ Embodiment 1 >

FIG. 2 is a view for explaining the structure of an intelligent multi-agent compressed air purger (hereinafter referred to as a compressed air purger) according to a first embodiment of the present invention. As shown in FIG. 1, the compressed air sprayer 100 according to the first embodiment includes a main body 110, a foam generator 130, a handle 140, and a hose 150.

A compressed air 10 is filled in the space inside the main body 110 and a discharge path 121 connected to the hose 150 outside the main body 110 is installed at an upper portion of the main body 110. A foam aqueous solution storage part 120 for storing a foam aqueous solution 20 is connected to a lower part of the discharge path 121 and a foam generating part 130 is installed inside the discharge path 121. Here, the foam aqueous solution 20 stored in the foam aqueous solution storage part 120 may be in a state where the digestion water and the foam stock solution (fire extinguishing agent) are mixed, or may contain additional additives.

A handle 140 for opening and closing the discharge path 121 is provided in the upper part of the main body 110 and a hose 150 for spraying the foam to the surface of the fire is attached to one side of the handle 140. The hose 150 is provided with a fourth foam 151 for increasing the foam density once before the foam generated by the foam generator 130 is injected through the directivity adjusting nozzle 152 at the end of the hose 150 Respectively.

Each of the components of the intelligent multi-agent compressed air purifier 100 shown in FIG. 2 will be further specified from the following description of the operation process.

First, when a fire occurs, the user unplugs the safety pin (not shown) and directs the directivity adjusting nozzle 152 of the hose 150 toward the fire direction, and then grasps the handle 140. The discharge path 121 is opened according to the grip of the handle 140. [

Here, the space inside the main body 110 is in a state of high pressure by the compressed air 10, and the inside of the foam aqueous solution storage part 120 made of a stretchable material faces the outside atmosphere through the discharge path 121 . Therefore, the foam aqueous solution storage part 120 is contracted due to the pressure difference between the inside and the outside of the foam solution storage part 120, and the foam solution 20 is pushed toward the discharge path 121 side.

The foam generating part 130 is provided on the discharge path 121 so that when the foam aqueous solution 20 enters the foam generating part 130, the foam is mixed with the compressed air 10 to form foam.

3 is a diagram for explaining a detailed configuration of the form generating unit 130. As shown in FIG. As shown in FIG. 3, the foam generator 130 is installed inside the discharge path 121. The lower end of the discharge path 121 is connected to the foam aqueous solution storage part 120 and the upper part is connected to the hose 150 side.

The foam generating unit 130 includes a foamed aqueous solution input path 133, a compressed air entering path 134, a compressed air injecting unit 135, a primary foaming unit 136, a secondary foaming unit 138, A portion 139 and a sealing means 132.

The foam aqueous solution entry path 133 is a passage through which the foam aqueous solution 20 enters and the foam aqueous solution 20 pushed out of the foam aqueous solution storage part 120 through the foam aqueous solution entry path 133 is passed through the primary foam part 136 As shown in FIG.

The compressed air inflow path 134 is a path through which the compressed air 10 enters and one side of the compressed air inflow path 134 is connected to the lower end of the compressed air injecting section 135 in the discharge path 121, And the other side is connected to the outside of the discharge path 121. Therefore, the compressed air 10 filled in the space of the main body 110 through the compressed air intake path 134 enters the lower end of the compressed air injecting unit 135. The compressed air 10 filled in the inner space of the main body 110 may be an ordinary atmosphere, but may contain an inert gas such as nitrogen, argon, or carbon dioxide.

In this embodiment, the compressed air 10 and the foam aqueous solution 20 are sprinkled through very fine holes in order to mix the foam aqueous solution 20 and the compressed air 10 to generate foam. That is, the compressed air injecting part 135 is provided on one side of the compressed air entering path 134, and the primary foaming part 136 is provided so as to surround the compressed air injecting part 135.

In the example shown in FIG. 3, the compressed air injecting unit 135 and the primary foaming unit 136 are a porous structure for injecting gas or liquid from either side through the fine holes formed on the surface in all directions . For example, the porous structure includes a ceramic porous filter and the like, and various types of known types can be used.

3, when the compressed air 10 enters through the lower end of the compressed air injecting part 135, the compressed air 10 passes through the complicated cavities inside the compressed air injecting part 135, Which is scattered in all directions through the fine holes of the nozzle. The compressed air 10 thus injected enters the primary foaming portion 136 surrounding the compressed air spraying portion 135. At this time, the foamed aqueous solution 20 is discharged from the lower end of the primary foaming portion 136, The foam aqueous solution 20 and the compressed air 10 are mixed with each other in a fine space inside the primary foaming portion 136 to form a foam. The foam thus formed is injected in four directions through fine holes on the surface of the primary foam portion 136.

The compressed air 10 and the foam aqueous solution 20 are rapidly moved to a high pressure along the minute spaces inside the compressed air injecting unit 135 and the primary foaming unit 136, The bubbles expand due to the sudden pressure drop, and foam is generated.

The compressed air 10 and the foam aqueous solution 20 are mixed in the porous structure composed of complicated and fine holes instead of simply injecting the compressed air 10 into the flowing foam aqueous solution 20 in this embodiment And the number of foams per unit space is very large (i. E., The foam density is high) because the size of the foam produced is very small and compact.

Foams escaping from the primary foaming portion 136 pass through the moving section 137 and pass through the secondary foaming portion 138 and the tertiary foaming portion 139 made of a porous structure one more time, The foam moves along the hose 150 and is once again densified at the fourth foaming part 151 and then sprayed onto the fire surface through the directivity adjustment nozzle 152. [ That is, as the foam moves along the hose 150, the dense foam may be joined together to increase the size of the foam. The foam is sprayed while maintaining the high foam density while passing through the fourth foam 151 again You can.

The sealing means 132 provided at the lower end of the primary foaming portion 136 is provided with the compressed air 10 filled in the main body 110 through the gap on the discharge path 121 through which the compressed air entering path 134 passes And prevents the foam aqueous solution 20 from entering into the foam aqueous solution entry path 133 or prevents the foam aqueous solution 20 entering through the foam aqueous solution entry path 133 from escaping into the space inside the main body 110.

The compressed air injecting unit 135 and the primary foaming unit 136 are spaced apart from each other by a predetermined distance in this embodiment, .

3, the porous structure having fine holes is used as the compressed air injecting unit 135 and the primary foaming unit 136. However, the foam generating unit 130 shown in FIG. The compressed air injecting part 135 'and the primary foaming part 136' are filled with fine particulate matter (in the form of a sphere such as beads, a tetrahedral material, or a pentaport) It can be produced in the form of a pore structure. Such void structure is also highly scattering effect of compressed air 10 or foam aqueous solution 20 due to complicated and fine voids. That is, referring to FIG. 5, in the structure in which spherical particulate matter such as a bead is complicatedly filled as the pore structure, the air or the foam aqueous solution 20 is sputtered while complicatedly moving. Therefore, it is possible to generate dense foam even in such a structure.

Of course, like the foam generator 130 '' shown in FIG. 6, the compressed air injector 135 '' may be fabricated as a cavity structure, the primary foam 136 '' may be fabricated as a porous structure, .

Also, the secondary foaming portion 138 and the tertiary foaming portion 139 for increasing the foam density of the foam produced in the primary foaming portion 136 may be also formed in the form of a porous structure or a void structure, Thus, a net made of a complex network or a wringer type may be used.

FIG. 7 is a view for explaining a fourth foam part 151 installed in the hose 150 of the compressed air blower 100 shown in FIG. That is, the compressed air 10 and the foam solution 20 are mixed in the foam generator 130 to generate a dense foam, and then the foam is moved along the hose 150, As shown in FIG. 7, the foam may be sprayed while maintaining a high foam density by further passing through the fourth foam portion 151 having a fine mesh or a wool-like fine hole. Of course, it is also possible to form the fourth foam 151 in the form of a porous structure or an air gap structure.

The primary foaming portion 136 and the compressed air spraying portion 135 may both be made of a porous structure or a pore structure, but the primary foaming portion 136 and the compressed air spraying portion 135 must be formed separately It need not be manufactured, and may be made into one structure according to the practice. That is, the foam aqueous solution entering path 133 and the compressed air entering path 134 are all connected to one side of one porous structure or the pore structure and the foam aqueous solution 20 and the compressed air 10 are formed into one bundle In the porous structure or the pore structure after being mixed. In this case, the name of the bundle of porous structure or void structure which is mixed with the foam aqueous solution 20 and the compressed air 10 is referred to as the primary foaming portion 136 or the compressed air jetting portion 135 Also, That is, it is important that the compressed air 10 and the foam aqueous solution 20 are mixed while passing through the fine pores in the porous structure or the pore structure, and then they are sprayed to form a dense and uniform sized foam. It is not important to distinguish the composition separately or to make meaning to the name.

High foam densities can be maintained until they are injected through the four adjustment nozzles 152, 252, 352 and 452.

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 sized foam has enhanced physical properties, resulting in high adhesion, resulting in increased vaginal and cooling effects, and also due to the effect of the addition through the additive added to the aqueous foam solution (20) Excellent digestive effect.

The foregoing description of the preferred embodiments of the present invention has been presented for the purpose of illustration and it will be apparent to those skilled in the art that various modifications, additions and substitutions are possible within the spirit and scope of the invention, And additions should be considered as falling within the scope of the claims of the present invention.
