Abstract

PURPOSE:To prevent gas from being discharged in a white smoke state during an extinguishing motion by a method wherein gas sucked from a suction device is guided through a gas guide passage toward a fuel oil level, and thereafter it is discharged to the outside of a device. CONSTITUTION:When a wick elevation type kerosene heater is extinguished, a suction device 13 is worked, and gas generated from a combustion wick is sucked in a casing 19 through a discharge passage 9, the internal space of a combustion tank 2, and a hole 10. Gas is guided toward a fuel oil level in the combustion tank 2 through a gas guide passage 18. Kerosene gas having a relatively high grain size and a high specific gravity produces dew and is gasified because of the gas guide passage 18 being relatively long, and flows in fuel oil along the inner wall of the gas guide passage 18. The gas guided to the fuel oil level through the gas guide passage 18 is brought into contact with kerosene 3 discharged on the fuel oil level through a communication port 20. An unliquefied kerosene component is adsorbed to the kerosene 3, remaining gas is discharged to the outside of a smell reducing device 17, and white smoke is almost prevented from generation during operation of the smell reducing device 17.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oil combustor odor reduction device, and particularly to an oil combustor odor reduction device that can reduce white smoke emitted from the odor reduction device. Regarding.

[Prior art]

A typical example of an oil combustor is a wick type oil combustor. The cough wick upper and lower type kerosene stove is the 4th Ff! As shown in J, the kerosene 3 in the combustion tank 2 is sucked up by the combustion wick 7, which is vertically slidable inside the core chamber interior 6 formed by the inner core tube 4 and the outer core tube 5, and then removed from the combustion tube. It is burned in 8.

In such a wick type kerosene stove, when the combustion wick 7 is immersed in the wick chamber interior 6 during extinguishing operation,
Incomplete combustion gas is generated by so-called slow combustion for several seconds to several tens of seconds, and even after the slow combustion is extinguished, unburned gas is generated until the combustion wick 7 is cooled. When these gases pass through the combustion tube 8, which is still at a high temperature, they pass through Xl! It is thermally decomposed into IR, causing a bad odor.

Therefore, as a method of reducing this bad odor, the gas generated during the fire extinguishing operation is discharged without passing through the combustion tube 8. That is, when extinguishing a fire, the inner diameter of the outer wick cylinder 5 is expanded slightly below the position of the upper end of the combustion wick 7 when the combustion wick 7 is immersed in the inner chamber 6 of the wick chamber, and the combustion tank 2 is expanded.
An exhaust passage 9 is formed which communicates with the internal space of the air conditioner. Further, a hole 10 is bored in the upper wall 21 of the combustion tank 2, and the odor reduction device 1 is disposed on the upper surface of the hole 10.

The odor reduction device 1 includes a micro motor 11 and a fan 1.
2 or the like (a suction pump or the like may be used); a casing 15 that accommodates the suction device 13 therein and is formed with a discharge port 14 for discharging the gas sucked by the suction device 13; A damper 16 is provided to prevent outside air (air) from flowing into the exhaust port 14 of the casing 15.

Therefore, when extinguishing the above-mentioned wick type kerosene stove,
The suction device operates, and the gas generated from the combustion wick 7 is transferred to the exhaust passage 9. Internal space of the combustion tank 2, hole 1
0 into the casing 19 through the outlet port 4.
from the device to the outside of the device. By doing so, the gas generated from the combustion wick 7 can be discharged without passing through the combustion tube 8, so that bad odor can be reduced.

[Problem to be solved by the invention]

Such a conventional oil combustor odor reduction device 1 has a structure in which the gas sucked in by the suction device 13 is immediately discharged as it is from the discharge port 14. Therefore, among the gases mentioned above, kerosene gas with relatively large particles is discharged as white smoke, which causes discomfort to the user.

Therefore, an object of the present invention is to provide an odor reduction device for an oil combustor, which prevents the gas from being emitted as white smoke when discharging the gas sucked by the device 13 during extinguishing operation. It is.

[Means to solve the problem]

The main means employed by the present invention in order to achieve the above object is to suck up the fuel in the combustion tank by a combustion wick surrounded by an inner wick cylinder and an outer wick cylinder and burn it. In an odor reduction device for an oil combustor in which generated gas is sucked by a suction device and discharged outside the device, a downward gas guide passage from the suction device to the fuel oil surface is provided, and the gas sucked from the suction device is This is an odor reduction device for an oil combustor, the gist of which is that the gas is guided toward the fuel oil surface in the combustion tank through a gas guide passage, and is then discharged outside the device.

[Effect]

According to the present invention, a downward gas guide passage from the suction device to the fuel oil surface is provided between the suction device and the discharge port of the odor reduction device, and the gas sucked by the suction device is efficiently condensed. After the liquefied gas is returned to the fuel, the remaining gas is discharged outside the device.

Therefore, the white kerosene gas, which has relatively large particles and becomes white smoke when discharged, collects downward because it has a higher specific gravity than air.
There, it is sufficiently liquefied and returned to the fuel, and only clean kerosene gas from which white smoke has been removed is discharged outside the device.

The figures are enlarged sectional views of essential parts of an oil combustor equipped with an odor reduction device according to an embodiment of the present invention, FIGS. 2 and 3'l! J
FIG. 2 is an enlarged sectional view of a main part of an oil combustor showing a modification thereof.

In the following description, the same reference numerals will be used for the same elements as those of the oil combustor equipped with the conventional odor reduction device shown in FIG. 4, and the description thereof will be omitted. Further, the following examples are merely specific examples of the present invention, and are not intended to limit the technical scope of the present invention.

In this embodiment, the odor reduction device 17 differs from the conventional odor reduction device 1 in that, as shown in FIG. This is because a gas guide passage 18 is provided.

Therefore, when a kerosene stove with an upper and lower wick is extinguished, the suction device 13 is activated and the gas generated from the combustion wick is transferred to the exhaust passage 9. Internal space of combustion tank 2.

Suction is drawn into the casing 19 through the hole 10. and,
The gas is guided toward the fuel oil level in the combustion tank 2 by the gas guide passage 18 .

At this time, among the gases mentioned above, kerosene gas with relatively large particles and those with heavy specific gravity are efficiently condensed and liquefied inside the gas guide passage 18, which is relatively long. The liquefied kerosene component flows down into the fuel oil along the inner wall of the gas guide passage 18.

The gas guided to the fuel oil surface by the gas guide passage 18 is discharged onto the fuel oil surface via the communication port 20 to which the discharge port 14 is connected, and comes into contact with the kerosene 3 to form unliquefied kerosene components. is adsorbed by the kerosene 3 and returned to the kerosene 3. The remaining gas is discharged outside the odor reduction device 17.

In this way, the gas sucked by the suction device 13 is efficiently liquefied, the liquefied kerosene components and the components adsorbed in the fuel are returned to the fuel, and only the remaining gas is transferred to the odor reduction device 1.
By discharging the odor to the outside of the odor reducing device 17, generation of white smoke when the odor reduction device 17 is activated is almost eliminated.

Also, 2nd F! ! As shown in J, the gas guide passage 1
The discharge port 14 at the tip of 8 may be opened and connected slightly below the equilibrium oil level of the communication port 20 to force the gas and fuel into contact and improve the adsorption of white smoke components. In this case, in order to effectively operate the suction device 13, a pressure sufficient to overcome the pressure of the oil level is required, but since the outlet 14 is normally closed by the oil level, the damper 16 is closed. It also has the advantage of being unnecessary.

Note that the discharge port 14 does not necessarily need to be connected to the communication port 20; for example, as shown in FIG. It may also be connected to the discharge member 21.
