Description

[Detailed description of the invention] This invention relates to a liquid vaporization device, and its purpose is to stabilize the amount of vaporized liquid by stabilizing the amount of atomized particles supplied from the atomization device to the vaporization device. There is a particular thing.

Conventional liquid vaporizers of this type have been used in liquid fuel combustion equipment and humidifiers, but the amount of atomized particles supplied from the atomizer to the vaporizer was unstable, resulting in the following drawbacks: there were.

That is, if a liquid fuel combustion device is used, the combustion state becomes unstable, and if a humidifier is used, the amount of humidification fluctuates greatly.

Therefore, the present invention attempts to solve the above-mentioned conventional drawbacks by connecting a drain pipe near the side of the rotating body in the direction of rotation of the atomized particle outlet of the atomizing device.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 29 denotes an oil supply pipe, one end of which opens into the pump case 28, and the other end of which opens onto the rotary plate 22.

Reference numeral 30 designates a drain pipe, one end of which opens into the sub-tank 27 and the other end of which opens near the side of the atomized particle outlet in the rotational direction of the rotating body inside the atomization container 10.

Reference numeral 31 denotes an oil pipe that communicates the leveler 32 and the sub-tank 27.

. 33 is a substrate.

Next, the operation will be explained.

First, the electric heater 2 is energized and the vaporizing cylinder 1 is heated to 200 to 25
Preheat to C.

When the motor 20 is energized after preheating is completed, the rotating plate 22, fan impeller 23, and pump impeller 2 fixed on the same axis
4 rotates.

As a result, a fixed amount of fuel in the sub-tank 27 is continuously supplied to the rotary plate 22 by the pump impeller 24, and the fuel is scattered in the tangential direction from the entire outer circumference of the rotary plate 22 due to centrifugal force and is atomized.

The atomized fuel passes through the opening 13 of the damper 12, hits the inner wall of the vaporization cylinder 1, and is gasified.

The fuel hitting areas other than the opening 13 of the damper 12 falls down the inner wall of the damper 12 and returns to the sub-tank 27 from the bottom of the atomization container 10 through the drain pipe 30.

On the other hand, the air sucked in by the fan impeller 23 enters the vaporizer 1 through the opening 13 of the damper 12, mixes with vaporized gas, and is ejected outward from the flame hole 7 of the burner head 6, forming a combustion flame 8. do.

Also, by rotating the damper 12, the opening 1
The third magnitude changes, and as a result, the amount of atomized fuel entering the vaporizer cylinder 1 increases or decreases, and at the same time, the air required for combustion also increases or decreases.

That is, by rotating the damper 12 in this way, the combustion amount can be adjusted while always keeping the air-fuel ratio constant.

For example, the angle of the maximum opening 13 of the damper 12 is set to 45°, and white kerosene is pumped onto the rotating plate 22 at 20V 0O by a pump.
If OKcal/h (approximately 2.5f/h) is supplied by the needle, the fuel entering carburetor cylinder 1 is 20.000X45°/36
0°, and 2,500 KCa1/h is obtained.

In addition, if the effective opening angle of the damper 12 opening 13 is gradually decreased depending on the relative position with the atomization container 10 and is set to 9°, then 50
This means that 0Kcal/h can be obtained.

In this way, by setting and rotating the opening angle of the damper 12, the combustion amount can be freely set and adjusted over a wide range.

Extinguishing the fire can be easily done by turning off the power to the motor 20 and stopping it.

Further, even if the opening 13 of the damper 12 is completely closed, the fire can be extinguished.

Next, the feature points of this embodiment will be explained.

That is, in this embodiment, the drain pipe 30 is connected to the outlet 11 of the atomizing container 10 near the side of the rotary plate 22 in the direction of rotation, as shown in FIG. 2, so that the following effects are achieved.

In this embodiment, the liquid is dispersed as atomized particles around the entire circumference by the rotating plate 22, and a part of the liquid enters the vaporization cylinder 1, and the rest hits the inner surface of the damper 12 and the atomizing container 10, and descends while the rotating plate A flow is formed along the direction of rotation.

For this reason, the liquid comes to concentrate at the outlet 11 portion of the atomization container 10.

In this embodiment, the drain pipe 30 is connected, so that the liquid can be effectively discharged downward, and as a result, a large amount of liquid does not accumulate at the bottom of the atomization container 10.

That is, by providing the drain pipe 30 near the atomized particle outlet 11 on the rotational direction side of the rotary body 22 installed in the atomization container 10, the fuel scattered from the rotating plate 22 flows into the atomization container 1.
Drain pipe 30 at the terminal end that rotates along the inner wall of
Since a large amount of fuel can be discharged from the atomization container 10, a large amount of fuel does not accumulate in the atomization container 10, and the amount of atomization can be stabilized.

Therefore, the amount of vaporization in the vaporization tube 1 does not become unstable due to the liquid flowing into the vaporization tube 1 from the bottom of the atomization container 10 as in the conventional case, and the combustion condition becomes extremely good.

As described above, according to the present invention, if applied to a liquid fuel combustion device, good combustion can be achieved, and if applied to a humidifier, the amount of humidification will not vary greatly.
