Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-pollution type waste oil stove that is used for heating while incinerating various waste oils mainly for automobiles.

[0002]

2. Description of the Related Art Conventionally, various stoves using waste oil as fuel for automobiles and the like have emerged, but the combustion temperature is high, so they are non-durable, and maintenance is difficult due to a complicated structure. There is a danger, it is difficult to clean the inside, and it is expensive and not widely used even in cold climates.

[0003]

[0005] Waste oil, mainly in automobile factories and gas stations, cannot be disposed of all over the country and is being polluted. A system that can process a large amount of waste oil in a short period of time would be extremely difficult, considering that a waste oil stove that can be used for heating while burning in the surroundings is one way, as a waste oil incinerator does not emit secondary pollution It is desirable that it is non-polluting type, that its structure is simple and easy to handle, that it be safe, that it has excellent durability and maintenance, and that it be inexpensive.

[0004]

In order to achieve the above object,
The rotary combustion waste oil incineration stove of the present invention is a cylindrical combustion chamber,
A waste oil tank, a blower, etc. are appropriately arranged, a lid is provided at the top of the combustion chamber, a square air injection pipe is fixed at the center, the combustion flame is lowered to the center of the combustion chamber, and the combustion flame and vortex are obtained, so that the combustion gas and air Has made exhaust gas smokeless by complete combustion. The air injection pipe has an integral structure at the upper part of the combustion chamber, and can be easily attached to and detached from the combustion chamber. Cleaning is performed from the top, and the accident of spillage due to excessive fuel supply from the conventional lower part is eliminated, and cleaning is facilitated. Waste oil is supplied by gravity from the waste oil tank to the combustion chamber via a control valve. The blower is connected to the blower tube and supplies air to the air injection tube. A heat shield is provided between the combustion chamber and the waste oil tank to prevent the temperature of the waste oil tank from rising.

[0005]

[Action] The waste oil is connected to the combustion chamber via a control valve from the waste oil tank attached to the combustion chamber, so that an appropriate amount of waste oil adjusted by the valve flows into the combustion chamber by gravity. For ignition, a small amount of kerosene is injected from the inspection window. Ignition while flowing waste oil little by little,
If the blower is turned after ignition, it will ignite easily. In the initial stage of ignition, combustion is performed by the primary combustion air pipe below the air injection pipe,
Due to the rise in temperature, secondary combustion occurs around the air injection pipe, resulting in rotational combustion.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a side view of a rotary combustion waste oil stove, on a base 1, a combustion chamber 2, a waste oil tank 3, a mixed water separator 5, a blower 4, and a blower pipe 1.
The air injection tube 12 at the center of the combustion chamber 2 is a square tube, and air injection holes 16 are provided at equal intervals at four corners as shown in FIG. 3 (see FIG. 4). From 4, the air is sent to the air injection pipe 12 through the blower pipe 10, and the air is injected off-center from each of the four surfaces, so that the combustion rotates. A primary combustion air pipe 13 is provided at the lower part of the air injection pipe 12 and an air injection hole is provided at the bottom (FIG. 5), which assists combustion immediately after ignition and eliminates smoke even when extinguishing the fire. It is transferred to a tube and completely burned by the secondary combustion of rotary combustion.

The waste oil tank 3 is separated from the combustion chamber 2 by a heat shield plate 6.
Equipped with waste oil separation device 5
Is supplied to the combustion chamber 2, and an air injection pipe 12 is welded to the upper lid 7 at the center of the combustion chamber 2 (see FIG. 3), and air is blown in from the blower 4 through the ventilation pipe 10. The lid 7 at the upper part of the chamber 2 has an exhaust gas port 11 and an inspection port 14 and ignites from the inspection port 14. The lid 7 is integrated with the air injection pipe 12 and can be easily attached to and removed from the combustion chamber 2 (FIG. 7). The burnt residue is cleaned from above. Since the bottom of the combustion chamber 2 is a round bottom, it can be done in a short time with a scraping rod and a fan-shaped scraping tool.

The process from ignition to extinguishing will be described. A small amount of kerosene is put into the combustion chamber 2 through the inspection window 14 of the lid 7 at the upper part of the combustion chamber 2 and a small amount of waste oil is discharged. The primary combustion is performed by the air in the primary combustion tube 13, and soon after the temperature of the combustion chamber 2 rises, the combustion shifts to the rotary combustion around the air injection tube 12 and becomes the secondary combustion. The fuel is adjusted so as to reach the temperature. If the flame rises from the inspection window 14, the adjustment valve 8 is closed and adjusted. The principle of the rotary combustion is as shown in the perspective view of FIG. This is a major feature of the present invention because the air is ejected off the center. To extinguish the fire, close the control 8 valve.
The fire is extinguished in a nearly smoke-free state to the end by one hole directed to the bottom of the bottom of the air injection pipe 12. Cleaning is easy to remove before the combustion chamber 2 is cooled. The mixed water separation device 5 is set at a position where a little heat is applied, and a drain valve 15 is provided each time fuel is supplied.
Drain with water.

[0009]

According to the rotary combustion waste oil incineration stove of the present invention, most of the flame turns into secondary combustion by the rotary combustion and rotates around the inner periphery of the combustion chamber. It is an ideal condition from the viewpoint of durability, and the mixing of combustion gas and air is enhanced by rotary combustion or the rotating combustion flame is reminiscent of propane gas, and the exhaust gas is largely smokeless. According to the second aspect, the structure in which the lid having the integral structure is easily attached and detached leaves nothing in the combustion chamber. The round bottom shape facilitates cleaning, and there is no release port at the bottom, so that even if the waste oil is oversupplied, it does not flow out and is safe. In addition, it is easy to apply DC 12V to the blower, so its use is widened. Also, the combustion chamber and air injection pipe, which are expected to deteriorate due to high temperature of the members, do not require complicated processing and are concerned about maintenance. No, the present invention such like believed that satisfy the objectives and problems.
