DETAILED DESCRIPTION

(8) The present invention will be described with reference to the accompanying drawings. FIG. 1 is a view illustrating an aerosol generating and injecting device according to the present invention.

(9) The pre-mixing tank 28 is configured to supply an aerosol solution to the mixing tank 11 through a pre-mixing procedure so as to supplement in real time an aerosol solution if it needs to uniformly mix the aerosol. The mixing tank is able to uniformly mix the aerosol solution inside the tank by rotating the wing 12 installed inside the tank and keep the mixed aerosol solution. The motor installed on the top of the tank is configured to rotate the wing 12 arranged along the central shaft of the tank.

(10) In order to generate a high temperature/high pressure aerosol, it is more advantageous that the gas and water are mixed uniform, and the mixture of the aerosol state is separately injected.

(11) According to the conventional method, the aerosol aqueous solution heated through a bypass line is bypassed, thus uniformly mixing the gas and liquid. In this case, it is easy to raise the temperature using the heater; there, however, is a problem in preparing a high pressure aerosol aqueous solution. The present invention is referred to a method wherein a pre-mixing tank is provided, by which water and gas can be uniformly mixed with the aerosol aqueous solution heated by the bypass line in an aerosol aqueous solution. More specifically, it is possible to more easily prepare a high temperature/high pressure aerosol in such a way to add the inputs which are made by the aerosol prepared through the pre-mixing tank. Here, the states of the bypassed aerosol aqueous solution and the aerosol aqueous solution inputted from the pre-mixing tank are different. When the state of the aerosol aqueous solution is a little stabilized through the mixing with the continued bypass, it will be transferred to the second tank.

(12) The aerosol aqueous solution and the aerosol particles may be inputted through a filling nozzle 13 installed at the top, and water can be inputted into the tank through the nizzle formed installed at the top.

(13) A level gauge 14 installed at the lateral side is connected to a drain 15 installed at the lower end, thus adjusting the water level inside the tank. The aerosol aqueous solution may be agitated and mixed while pressuring the inside of the tank up to the level required for the compressed air or nitrogen gas to be inputted into the tank so as to pressurize the tank.

(14) The aerosol aqueous solution discharged from the tank will be injected into a second tank 17 in a high pressure state through the gear pump 16 and will be mixed with the compressed air or nitrogen gas which is injected through another passage, and will be injected into the second tank 17.

(15) The aerosol aqueous solution may be recirculated to the mixing tank 17 through a bypass line 19 until a predetermined initial flow quality of the aerosol aqueous solution becomes stabilized.

(16) If the flow quantity of the aerosol aqueous solution is stabilized, the aerosol and the compressed air or the nitrogen gas is injected through the binary fluid nozzle 18. The binary fluid nozzle 18 will mix the aerosol and air and generate a uniform pattern of perfect fine spray sprays. The binary fluid nozzle is provided to generate a uniform pattern of fine particles. Alternatively, it may be implemented in another type in accordance with the speed and mixing of the inputted liquid and air. FIG. 2 is a view illustrating an embodiment of this fine spray. The fine spray provided at the top in FIG. 2 shows that it is formed in a folding fan due to a difference between the pressure of air and the pressure of aerosol, thus forming a different shape from each other.

(17) FIG. 3 is a view illustrating an embodiment of the binary fluid nozzle. The configuration of a nozzle may be changed based on the flow of liquid and gas and if the air and liquid are independently controlled.

(18) FIG. 4 is a view illustrating a configuration which allows mixing an aerosol and vapor sprayed from the binary fluid nozzle, a compressed air, a nitrogen gas or a mixture thereof. A fine spray can be formed as it is discharged from the binary fluid nozzle. A mixing ring 21 may be installed where the fine spray is formed. The mixing ring is configured in a ring shape, and a plurality of holes 26 are formed on the outer surface thereof. A mixture (a transfer gas) of steam and a nitrogen gas (or a compressed air) can be sprayed through the holes formed at the mixing ring. The aerosol and transfer gas which are present in a fine spray state, are mixed and discharged through the exit of the second tank.

(19) If the aerosol is generated in the aforementioned way, the high pressure condition can be satisfied by adjusting the initial pressure of the mixing tank 11, and the temperature of the aerosol can be raised in such a way to install a heater between the tanks. In particular, an aerosol satisfying the condition of the pressure which is higher than before can be obtained by installing the pre-mixing tank of the present invention.

(20) FIG. 5 is a view illustrating a mixing ring and a transfer gas spray hole which is formed at an outer circumferential surface of the mixing ring. The transfer gas sprat hole may allow uniformly spraying the vapor, compressed air, nitrogen gas or a mixture thereof which are supplied to the mixing ring. The binary fluid nozzle disposed in the center of the mixing ring may allow preventing the pattern of the aerosol from attaching to the wall surface. For this, the binary fluid nozzle sprays close to the wall surface of the second tank so as to prevent the pattern of the aerosol injected through the binary fluid nozzle disposed in the center of the mixing ring from being adsorbed to the wall surface while it is mixed covering the aerosol.

(21) Moreover, a mixing ring block part 31 is provided at the mixing ring. Since the agitation is not carried out by the wing in the second tank 17, a uniform mixing may not be available. If the mixed gas is sprayed with the aid of the mixing ring, since the opening through which the mixed gas comes in, positions at the top, the flow speed of the mixed gas may differ at the upper and lower parts of the mixing ring. If the mixing ring block part 31 is provided at a portion symmetrically matching with the opening, the flow speed of the mixed gas discharged from the transfer gas spray hole 26 around the mixing ring block part 31, may become fast, so the discharge speed of the mixed gas can become similar together. For this reason, even though there is not any agitating device, for example, a wing, it is possible to generate a more uniform aerosol.

(22) As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
