Abstract

PURPOSE:To obtain an offensive gas incinerator which has a low running cost with a simple structure. CONSTITUTION:The offensive gas incinerator comprises a watertight chamber 41, a heating chamber 45, an incinerating chamber 50 and an exhaust cylinder 5. An incinerating tray 51 formed in a dome shape of stainless steel is installed at a lower part of the chamber 50. The tray 51, having many pores 52, is heated by a gas burner 4 in the chamber 41 so that it may become red-hot. Offensive gis is passed through the pores 42 of the red-hot tray 51 via the chamber 41, and xylene, toluene, etc., are thermally decomposed at this time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for burning offensive odor gas, and more particularly to an apparatus for incinerating offensive odor gas containing xylene, toluene and the like.

[0002]

BACKGROUND OF THE INVENTION In recent years, it has been a problem to release these malodorous gases into the atmosphere from a factory that handles gases such as xylene and toluene, which are sources of malodorous substances. Will be enforced. Manufacturers of nets for fishing and fishing nets treat the nets with xylene for the purpose of preventing seaweeds, moss and dirt from adhering to the nets. Conventionally, the malodorous gas containing xylene is diluted with raw gas. Although it was released into the atmosphere, it will be greatly regulated in the future.

By the way, in factories handling a large amount of xylene and toluene in the paint manufacturing industry and the coating industry, the malodorous gas is decomposed by a desolvation method. However, the dissolution method requires large-scale equipment and is not suitable for small and medium-sized factories.
In small and medium-sized factories, it is possible to burn offensive odor gas with a gas burner, but this requires a large amount of fuel gas, which results in high running costs.

[0004]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a malodorous gas incinerator having a simple structure and a low running cost.

In order to achieve the above object, the malodorous gas incinerator according to the present invention comprises a stainless steel incinerator plate having a large number of small holes and a gas burner for heating the incinerator plate to red heat. The odorous gas is sent to the incinerator and released into the atmosphere.

When the malodorous gas passes through the small holes of the incinerator which is heated red, the components such as xylene and toluene are decomposed, and these components become almost zero. The present invention has a simple structure in which the incinerator and the red-hot gas burner are the main components, and the malodorous gas feeding means and the exhaust means are attached to the incinerator. Moreover, the fuel is only the gas (usually propane gas is used) supplied to the gas burner that heats the stainless incinerator red, and the fuel cost for incineration is extremely low and the running cost is low.

Further, in the malodorous gas incinerator according to the present invention, it is preferable that a watertight chamber is provided below the incinerator and the malodorous gas is sent to the incinerator through the watertight chamber. This is to avoid the gas explosion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the malodorous gas incinerator according to the present invention will be described below with reference to the accompanying drawings. Figure 1 shows the installation status of the incinerator, 1 is a factory, 2 is an explosion-proof tank, 3
Is a fire wall, 4 is an incinerator body, and 5 is a pedestal made of concrete.

Xylene is used in the factory 1, and 100
It is assumed that a foul-smelling gas containing ~ 200 ppm xylene is generated. Absorption pipes 11, 11 are installed in the factory 1,
Malodorous gas is guided to the explosion-proof tank 2 by the two air pumps 12, 12. The explosion-proof tank 2 is filled with a predetermined amount of water, and the ends of the absorption tubes 11 and 11 are submerged in water. Piping 2 made of stainless steel from the top of the explosion-proof tank 2
1 is drawn out, and this pipe 21 penetrates the fire wall 3 and is connected to the incinerator main body 4. That is, the malodorous gas in the factory 1 is sucked by the absorption pipes 11 and 11, passes through the water in the explosion-proof tank 2, and is sent to the incinerator body 4 through the pipe 21.

FIG. 2 shows the internal structure of the incinerator body 4,
It is composed of a watertight chamber 41, a heating chamber 45, an incinerator chamber 50, and an exhaust stack 55 in order from the bottom. A dome-shaped incinerator 51 is installed below the incinerator 50. This incineration dish 51
Is made of stainless steel and has a large number of small holes 5 that penetrate the front and back.
2 are formed uniformly on the entire surface. A propane gas burner 46 is installed in the heating chamber 45, and a mixed fuel of propane gas and air is fed from a supply pipe 47. This propane gas burner 46 is the stainless steel incinerator 51 described above.
It is for making the red hot.

The watertight chamber 41 is filled with a predetermined amount of water through the water inlet 42, and the end of the pipe 21 is submerged in water. This watertight chamber 41 is the same as the explosion-proof tank 2 in the factory 1
It is installed to prevent the induction of gas inside. Further, a partition wall 43 having a large number of small holes 44 is installed above the watertight chamber 41.

In the incinerator having the above structure,
The xylene gas (concentration 100 to 200 ppm) in the factory 1 absorbed by the absorption pipes 11, 11 is guided to the watertight chamber 41 via the explosion-proof tank 2 and rises to the incinerator 51 through the gap of the gas burner 46. The incinerator 51 is in a state of being red-heated by the gas nanar 46, and xylene gas passes through the small holes 52 of the incinerator 51. During this passage, xylene becomes water and carbon dioxide gas, and finally hydrogen, oxygen, carbon dioxide gas. And is discharged from the exhaust pipe 55. The released gas contains almost no xylene, which causes odor.

This embodiment is a factory with an inner product of 1500 m ³ ,
It is designed on the assumption that 0.4 m ³ of xylene gas (100 ppm) is generated in 1 minute. As for the size, the total height of the watertight chamber 41 and the heating chamber 45 is 1 m, the height of the incineration chamber 50 is 1.5 m, and the diameter of these is 80 cm.
The height of the exhaust pipe 55 is 2 m, the diameter thereof is 40 cm, and the height of the hood 56 is 30 cm.

Each air pump 12 has a flow rate of 0.2 m ^{3 /} min.
And the velocity of the gas passing through the incineration chamber 50 is 0.8 m / min. Further, the gas burner 46 can adjust the heating power in five stages, and the incinerator 51 is heated to about 700 to 800 ° C. The air volume of the air pump 12 and the heating power of the gas burner 46 are appropriately adjusted depending on the amount of xylene generated.

The malodorous gas incinerator according to the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made within the scope of the gist.
