CONSTITUTION:Odor gas, flowing through each communicating pipe 40, is injected such that, since the lower edge of an inner cylinder 80 is positioned so that it runs across the upper end of each communicating pipe 40, a part thereof is injected in the inner cylinder 80 in a manner to enable a vane part 92 to surround flame, and another part thereof is injected in an annular gap part 88 formed by the inner cylinder 80, an outer cylinder 46 and a flange part 84. Thereafter, the odor gas is heated by the outer periphery of the inner cylinder 80, and rises along the outer periphery up to the flange part 84, the odor gas is cooled by the inner periphery of the outer cylinder 46 and decends, and after it enters the interior of the inner cylinder 82 from the lower part of the annular gap 88, it is swirled upward by flame. This prevents the outer cylinder from being directly heated, resulting in improvement of durability of the outer cylinder.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an odor gas combustion tube for a vacuum car, and more specifically, to a vacuum car that efficiently burns odor gases generated during excrement pumping work, makes them odorless, and then releases them into the atmosphere. Regarding the odor gas combustion tube.

The smelly gas generated during the work of pumping up human waste with a vacuum car causes discomfort to workers and surrounding residents, and the gas contains hydrogen sulfide and other beach components that are harmful to the human body. Removing this odorous gas is an important social problem in Japan, where sewage facilities are not yet fully developed and human waste removal work is essential.

In the past, attempts have been made to remove odor residue using various methods, but burning the odor gas to remove toxic components and making it odorless before releasing it into the atmosphere has yielded good results in terms of quantity and quantity. There is. However, in conventional odorous gas combustion tubes installed in vacuum cars, the temperature inside the combustion tube becomes high and the rising air current causes turbulence in the odorous gas, which is emitted without being completely combusted. There were some problems such as not being removed. In order to solve this problem, the present inventor has attempted to improve a portion of the burner provided in the odor gas combustion tube.

The improvement is shown in Figure 1. The general reference numeral 20 indicates an odor gas combustion tube, and this odor gas combustion tube 2o is composed of a combustion tube 22 and an introduction part 24. The odorous gas passes through the introduction pipe 26 from the human waste tank (not shown) of the vacuum car, passes through the introduction section 24, and enters the combustion tube 2 above the introduction section 24.
The fuel passes through a communication pipe 40 that also serves as a pillar supporting the fuel cell 2, and is sent to the combustion tube 22. The combustion tube 22 is formed of a cylindrical outer tube 46, the upper end of which is open, and the communication pipe 40 penetrates into the peripheral edge of the lower surface. Further, the central part of the lower surface of the outer cylinder 46 is opened in the shape of a circular hole, and a fuel gas discharge cylinder 52 is erected in this opening toward the inside of the outer cylinder 46, and a burner 18 is provided so as to close the opening from below. ing. This burner 18 is formed by an air intake 56, a spark plug 60 and a nozzle 62. The upper end of the communication pipe 40 is connected to the burner 1 where the odor gas is connected.
8 and the fuel gas drainage tube 52 toward the flame rising in a cylindrical shape at the center of the combustion tube 22, diagonally upward and in a direction substantially tangential to the cylindrical flame. Reference numeral 48 denotes a weir plate, and the lower surface of this weir plate 48 is formed into an open surface slightly convex downward, and a through hole 50 is opened in the peripheral edge. Reference numeral 66 denotes exhaust holes, which are provided through the upper peripheral surface of the outer cylinder 46 at an appropriate number of equally spaced intervals. Further, a shielding plate 76 is fixed to the upper end of a plurality of plates 74 erected at predetermined intervals on the upper part of the hood 68 which is formed of a net body except for the upper part so as to cover the entire outer cylinder 46. A through hole 72 is formed. As described above, the inventor has
A stinky gas combustion cylinder for a vacuum car has been proposed (Japanese Patent Application No. 1983-69757).

In the conventional example, as described above, the fuel gas discharge tube 5
The flame rising from 2 hits plate 5 (5) and spreads in the circumferential direction, mixing odor gas and burning. Therefore,
The inner wall of the outer cylinder 46 is directly burned by the flame and reaches an extremely high temperature, which is dangerous and can cause burns if it comes in contact with the body.Therefore, a protective cover is required, which increases the cost. Because of this, it is prone to burnout and has poor durability. In addition, even if you try to replace or repair the outer cylinder 46 in this case, each communication pipe 4
There were various difficulties such as not being easy because the 0 penetrates.

The present invention has been made in view of the above-mentioned difficulties, and aims to provide a highly durable odor gas combustion cylinder.The present invention is characterized by being mounted on a vacuum car so as to communicate with its human waste tank, and during pumping work. Consisting of an odor gas introduction part for introducing odor gas in the human waste tank, and a combustion tube located above the odor gas introduction part for burning the odor gas, the introduction part and the combustion tube are: A burner is disposed at the periphery of each cylinder and communicates with each other through a plurality of communicating pipes whose upper ends penetrate into the combustion cylinder, and at the center of the lower surface of the combustion cylinder, a burner is provided to raise a flame into the combustion cylinder. In the odorous gas combustion cylinder, in which a TLT plate having an outer diameter smaller than the inner diameter of the combustion cylinder is arranged horizontally at the upper part of the combustion cylinder, an inner cylinder is installed in the combustion cylinder so as to surround the flame rising from the burner. A closing member is provided to close the upper part of the gap formed by the outer wall surface of the inner cylinder and the inner wall surface of the combustion cylinder to form an annular gap, and the odor gas ejected from the communication pipe is applied to the flame. A vane portion is disposed above the open end of each communicating pipe to feed the flame so as to be entwined with the flame from a substantially tangential direction.

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 2 is a sectional view showing a state in which an inner cylinder 8o is provided in the odor gas combustion fiJ20. The inner surface 8o is formed by an inner cylinder main body 82, a flange portion 84 serving as a closing member provided on the upper outer wall surface of the inner cylinder main body 82, and a vane portion 92 provided on the lower inner wall surface of the cylindrical main body 82. .

An annular flange portion 8 is provided on the upper outer wall surface of the inner cylinder main body 82.
4 is provided, and the outer peripheral edge of this flange portion 84 is connected to the outer cylinder 46.
An annular gap 88 is defined, which airtightly abuts the upper part of the inner wall and is opened downward by the outer cylinder 46°, the inner cylinder 80, and the flange portion 84. The cylindrical main body 82 is attached to the outer cylinder 4 by four legs 90 (however, only two are shown) so that its lower edge is positioned across the center of the open upper end of each of the communicating pipes 40.
6 It is placed on the inner bottom surface. Further, the aforementioned vane portions 92 (only two pieces are shown) are attached to each of the communication pipes 40 so that the odor residue ejected from the communication pipes 40 rises in a right-handed spiral shape.
It is fixed to the inner wall of the inner cylinder main body 82 above the opening end of 0 at an angle of 45 degrees.

Reference numeral 48 denotes a service plate, the outer diameter of which is smaller than the inner diameter of the inner cylinder 80, and is supported by an appropriate support member so as to be horizontally positioned on the upper inner wall of the inner cylinder 80.

Next, the operation of this embodiment will be explained. When the vacuum car starts the pumping operation, the odor scum in the human waste tank enters the introduction part 24 through the introduction pipe 26. Subsequently, the valve 34 is pushed up, and the fuel is injected into the combustion cylinder 22 through the city pipe 40.

By rotating the operating knob 44, the E'IS ejected from the nozzle 62 is ignited by the spark plug 60, causing a flame to rise from the fuel gas discharge tube 52 toward the first plate 48. The odor gas that has passed through each communication pipe 40 passes through the cylinder 80 above the upper end of each communication/f pipe 40.
Since the lower end edge is in a transverse position, part of the flame is ejected into the inner cylinder 80 by the blade part 92 so as to enclose the flame, and part of it is ejected into the annular gap defined by the inner cylinder 80, the outer cylinder 46, and the flange part 84. It is ejected at 88. The odor gas ejected into the annular gap 88 is warmed by the outer peripheral surface of the inner cylinder 80 and rises along the outer peripheral surface to the flange portion 84.
It is cooled by the inner circumferential surface of the outer cylinder 46 and descends into the annular gap 8.
8 enters the inner cylinder 82 from the lower part and is engulfed in flame. Therefore, the heat inside the inner cylinder 80 is not directly transmitted to the outer cylinder 46, so the temperature does not rise and there is no risk of getting burned even if you touch it with your hand.
). On the other hand, since the annular gap 88 serves as a kind of heat retaining part, the temperature inside the inner cylinder 80 is effectively increased, and the combustion efficiency is increased (the blade part 92 causes the flame to spread from the tangential direction). The ejected odorous gas is entangled in the central part of the flame column and burns in the entangled state.
It is completely combusted on the lower surface of the four plates 48, removing components from the surface and rendering the burnt odor harmless. This odorless and harmless waste rises from the gap between the inner plate 48 and the inner cylinder 80, passes through the exhaust hole 66) and the air lower 0, and is discharged into the atmosphere.

In the above embodiment, the upper end of the communication/f-bub 40 may be cut horizontally. In addition, the inner cylinder main body 82 flange portion 8
4 and the blade portion 92 may be provided separately and formed integrally with the stinky gas combustion cylinder 20, or may be formed integrally as the inner cylinder 80 and detachably attached to the outer cylinder 46. In this way, the inner cylinder 80, which is prone to misalignment and burnout, can be easily replaced, and there are advantages such as being able to extend the life of the odor gas combustion cylinder 20.

As described above, according to the present invention, the part of the odorous gas ejected from the communication pipe by the vanes spirally entangles and burns in the flame column rising straight up, and the part of the odorous gas ejected into the annular gap acts as a combustion barrier. Therefore, the odorous gas is combusted very efficiently, which helps to save fuel and has the remarkable effect that it is completely harmless and odorless when released.

Furthermore, since the inner cylinder is provided within the outer cylinder, the outer surface is not directly heated, so there is no risk of burnout. Furthermore, even if the cylinder overheats and burns out, it can be easily replaced, and it is also excellent in terms of durability. Furthermore, the outer cylinder does not reach a high temperature and there is no risk of getting burned even if touched, making it safe. In addition, it is effective in that it does not require a protective cover and costs can be reduced.

Although various explanations have been given above with reference to preferred embodiments of the present invention, it goes without saying that the present invention is not limited to the above-mentioned embodiments. Of course, many modifications may be made without departing from the spirit of the invention, such as forming a flame column so that the odor gas is spirally entwined with the flame column.
