Description

[Detailed Description of the Invention] The present invention relates to a deodorizing device that thermally decomposes an odor-containing process gas to convert it into an odorless gas.

Generally, the processing gas containing odor is heated to approximately 750°C to 800°C.
It is known that when heated to pyrolysis, it is completely converted into a smokeless and odorless gas.

By the way, in the past, the inside of a furnace lined with bricks was heated to the above temperature using, for example, a heavy oil burner, and odor-laden gas was supplied into the furnace, but this method had extremely low thermal efficiency, so the fuel It was expensive, and because the inside of the furnace was kept at a high temperature, the lifespan of the bricks was extremely short and their durability was poor.

The present invention has been made in view of the above circumstances, and includes an outer cylinder provided at a predetermined interval around the outer periphery of a metal inner cylinder having a plurality of vent holes, and a A guide body for preheating the processing gas is provided protrudingly, and a supply port is provided between the inner cylinder and the outer cylinder to supply the processing gas containing odor and rotate it along the inner cylinder. A plurality of guide bodies for preheating and guiding the processing gas are provided around the inner cylinder in a continuous spiral manner, and a plurality of ventilation holes are provided in an inclined manner in the inner cylinder to allow the processing gas to flow inside the inner cylinder. To provide a deodorizing device with high thermal efficiency and improved durability by providing a burner device near the supply port that injects heated air while rotating and supplies heated air into the inner cylinder. The purpose is to

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

Reference numeral 1 denotes a metal inner cylinder, and substantially annular flanges 2 and 3 are fixed to both ends thereof.

Reference numeral 4 denotes a burner mounting body bolted to the flange 2, and a burner device 7 consisting of, for example, a heavy oil burner 5 and a blower device 6 is attached to this.

Reference numeral 8 denotes an outer cylinder having a larger diameter than the inner cylinder 1, and a substantially annular fixing ring 9 is fixed around the outer circumference of one end of the outer cylinder.

Then, by inserting the inner cylinder 1 into the outer cylinder 8 from one end side, the flanges 2 and 3 are brought into contact between the inner layers of the outer cylinder 8, and the fixing ring 9 and the burner mounting body 4 are tightened with bolts, etc. Thus, the outer cylinder 8 is arranged around the inner cylinder 1 at a predetermined interval.

Reference numeral 10 denotes a guide plate as a plurality of guide bodies formed in a substantially arc shape with a predetermined width. These buttons are continuously fixed by welding or the like so as to form a spiral shape in the left-hand thread direction around the outer circumference of the inner cylinder 1, thereby creating a substantially spiral ventilation between the inner cylinder 1 and the outer cylinder 8. A road 11 is formed.

Each guide plate 10 is slightly inclined toward the 7-lunge 3 direction toward the tip, and a slight gap is formed between the tip of each guide plate 10 and the inner surface of the outer cylinder 8. are doing.

Reference numeral 12 denotes a supply port formed at the upper part of the outer cylinder 8 slightly closer to the flange 2 so as to face the ventilation passage 11, and a supply port body 13 for supplying the processing gas containing odor is provided to this port. It is being

The supply port body 13 is continuous in the substantially tangential direction of the ventilation path 11, that is, the outer cylinder 8, and the processing gas supplied from the supply port 13 to the ventilation path 11 flows through the ventilation path 11 in the direction indicated by the arrow. As a result, it rotates along the periphery of the inner cylinder 1 and moves in the 3 directions of the 7 flange.

Reference numeral 14 denotes a plurality of vent holes that are inclined and bored in the inner cylinder 1 at a predetermined interval from each other approximately in the middle of the vent passage 11;
These vents 14 are oriented toward the ventilation path 11 in the direction opposite to the arrow entry direction, which is the flow direction of the processing gas, so that the processing gas flowing through the ventilation path 11 passes through each ventilation port 14 smoothly. The liquid is ejected into the inner cylinder 1 and flows inside the inner cylinder 1 while rotating in the direction indicated by the arrow.

Note that, for example, a process gas is supplied to the supply port body 13.
A blower (not shown) is attached that blows air toward.

An exhaust pipe 15 has one end connected to the flange 3, and the other end is connected to a chimney or the like via, for example, an exhaust blower.

Next, the operation of this embodiment configured as described above will be explained.

Heated air is supplied into the inner cylinder 1 by the burner device 7 to bring the inside of the inner cylinder 1 to a high temperature state of a predetermined temperature, for example, 750°C to 800°C.

Then, when the processing gas containing odor is blown into the supply port body 13 by a blower (not shown), this gas is blown through the supply port 12 in the direction of the arrow in the air passage 11, and the gas is blown into the ventilation port 13.
It is sequentially supplied into the inner cylinder 1 from .

Since the guide plate 10 acts as a heat dissipation fin for the inner cylinder 1, the heat in the inner cylinder 1 is exchanged with the processing gas in the ventilation passage 11. While flowing through the inner cylinder 1, heat is applied from the surroundings of the inner cylinder 1 and the guide plate 10 to preheat it, and then the preheated processing gas is spouted from the vent 14 into the inner cylinder 1 so as to rotate in the direction indicated by the arrow. It is mixed with hot air at a high temperature of 750° C. to 800° C. in the inner cylinder 1, heated and thermally decomposed to become an odorless and smokeless gas, which is released into the atmosphere through the exhaust pipe 15, for example, from a chimney.

According to this embodiment, the outer cylinder 8 is provided around the inner cylinder 1 at a predetermined interval, and the processing gas containing odor is supplied to the ventilation passage 11 provided around the inner cylinder 1. As a result, a heat insulating layer of gas is formed around the inner cylinder 1, and before the processing gas is supplied to the inner cylinder 1, it is preheated by the inner cylinder 1 and the guide body 10 in the ventilation passage 11, and The air is ejected from the vent 14 as it rotates in the direction of the arrow in the inner tank 1 and is thoroughly mixed with the hot air, which greatly improves thermal efficiency and reduces the fuel consumption of the burner device 7, making it more economical. Becomes excellent in sex.

Furthermore, before the processing gas enters the inner cylinder 1, it is sufficiently preheated in the ventilation path 11 formed by the guide plate 10, which also functions as a radiation fin, so that the temperature inside the inner cylinder 1 is rapidly cooled by the processing gas. There is no risk of overturning, and you can always maintain the best operating condition.

Since the inner cylinder 1 is made of metal and is cooled from the outside by the processing gas, its lifespan can be significantly improved compared to those of conventional structure.

Since a gap is provided between the tip of the guide plate 10 and the outer cylinder 8, the heat of the inner cylinder 1 is not directly transmitted to the outer cylinder 8.

In this case, it is more effective to interpose a heat insulating material in the gap.

Furthermore, according to this embodiment, since the supply port 12 is provided near the burner device 1, one end of the inner cylinder 1 near the supply port 12 is more fully exposed to the inner cylinder 1 via the guide plate 10 than the other portions. Since the inner cylinder 1 is cooled, one end of the inner cylinder 1 located near the burner device 1 is prevented from becoming overheated compared to other parts. Even if the processing gas supplied near the burner device 7 is preheated to a low degree by the guide plate 10, the processing gas with a lower temperature than other parts is supplied near the burner device γ, resulting in a low temperature. Since the burner device T is cooled by the processing gas, overheating of the burner device γ is also prevented, resulting in a longer service life and extremely excellent durability.

As described above, the present invention can provide a deodorizing device that can improve thermal efficiency, reduce fuel consumption, and is highly economical, as well as having significantly improved durability.
