PURPOSE:To dry, deodorize and incinerate by one heat source by arranging a rotary drum type drier at the top of an incinerating chamber, and forming the exhaust gas hole of the chamber and a discharge port of the drier in a connecting state, and arranging a gas vent tube from the vicinity of an inlet of the drier to the chamber. CONSTITUTION:A rotary drum type drier 9 is arranged at the top of an incinerating chamber 2, and the chamber 2 is heated by a burner 4 to introduce hot gas into the drum 9 through an exhaust gas hole 7A to dry a material 15 to be incinerated. Then, when a suction blower 14 is operated and water is injected from nozzles 13B,.., offnsive odor generated in the drum 9 is introduced into a shower cylinder 13A through a gas vent tube 12, substance to be dissolved in the water is dropped, gas is sucked by the blower 14, introduced into the chamber 2, and incinerated by the heat of the burner 4. As the drum 9 is rotated, the material 15 is dropped on an incinerating base 3, and incinerated by the burner 4. Thus, a deodorizing dry incinerator 1 can dry, deodorize and incinerate the material by one burner, and can be reduced in size.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a deodorizing, drying incinerator, and particularly to a deodorizing, drying incinerator suitable for incinerating substances that generate foul-smelling gases.

[Conventional technology]

Household household waste and industrial waste should be disposed of by incineration as much as possible, as disposal sites are limited. However, waste requires three steps: drying, deodorizing, and incineration. Conventionally, the waste was first dried in a rotating drum dryer, and the odor gas generated from the dryer was removed by a deodorizing device. to deodorize it,
The dried material to be processed is incinerated in an incinerator.

[Problem to be solved by the invention]

In the incineration process, since the incinerator, drying furnace, and deodorizing device are separate, it is difficult to select a location for installation, and it is especially difficult to install them in a narrow space. Further, each of the incinerator and drying furnace requires a heat source device such as a burner, which increases the cost of managing them. Furthermore, when the deodorizing device requires a burner, there is a problem in that heat sources must be managed at three locations in total.

In view of these circumstances, the present invention was developed for the purpose of providing a deodorizing, drying, and incinerator that can perform drying, deodorizing, and incineration using a single heat source.

[Means to solve the problem]

In order to solve the above-mentioned problem and achieve the object, this invention disposes a rotating drum type dryer in the upper part of the incineration chamber, and forms the exhaust hole of the incineration chamber and the discharge port of the dryer in a continuous manner, thereby discharging the heat of incineration. In addition to drying, a degassing pipe was installed between the vicinity of the input port of the dryer and the incineration chamber, so that the odor generated in the dryer was incinerated in the incineration chamber.

[Effect]

This invention configured as described above has the following effects.

The incineration chamber can incinerate materials to be incinerated using a burner. Hot air generated by incineration of the material to be incinerated is introduced into the rotating drum of the dryer to dry the material. The rotating drum has scraping blades installed on the inner surface of the inner cavity, and as the drum rotates, the material to be dried inside is scraped up and falls, and while this process is repeated, it is dried with hot air and sent to the input port side. From there, it moves toward the outlet and falls from the outlet into the incineration chamber. The rotating drum has a horizontally long cylindrical shape and is disposed with a downward slope toward the discharge port, so that the material to be dried can gradually move from the input port side to the discharge port side as the drum rotates.

A blower is installed in the gas vent pipe, and the suction force of the blower causes the odor (mainly sulfide) generated in the rotating drum to be sent to the incineration chamber, where it is incinerated by the firepower of the burner.

〔Example〕

Embodiments of the invention will be described based on the drawings.

FIG. 1 is a schematic front view showing one embodiment of a deodorizing drying incinerator.

In the incinerator 2 of the deodorizing incinerator 1, an incinerator 3 is disposed at the lower left in the figure, and a burner 4 is disposed at the lower right. In addition, a partition wall 5 is arranged in the upper half of the incineration chamber 2 so as to partition the left and right sides in the figure, and the right side of the partition wall 5 is divided into a smoke exhaust section 6 and the left side is a heating section 7. There is.

A smoke exhaust hole 6^ is formed in the ceiling of the smoke exhaust section 6, and an exhaust hole 7A is formed in the ceiling of the heating section 7.

A rotary drum dryer 9 is disposed in the upper part of the incineration chamber 2 via support wheels 8, 8, with a discharge port 9BrpJ inclined downward.

The rotary drum type dryer 9 has a general configuration, in which a horizontally long drum 9A is rotatably supported at its base end by two support wheels 8, 8..., and the drum 9A is rotated by a drive mechanism 10. Ru. The drum 9A has a discharge port 9B opened in a portion located above the exhaust hole 7^, and raking blades 9C, 9C...・is provided. An input port 9D is opened at the center of the right end surface of the drum 9A in the figure.
A lower delivery portion 11A of the hopper 11 is inserted into D. A screw conveyor I is installed in the delivery section 11A of the hopper.
The IB is moved inwards, and the screw conveyor 11B is driven by the driver 10.

Further, a gas vent pipe 12 is disposed in communication with the upper edge of the hopper 11 at a position close to the burner 4 of the incineration chamber 2.

A dust removal device 13 and an intake blower 14 are interposed in the middle of the gas vent pipe 12.

The dust removal device 13 has a fountain nozzle 1 in the shower cylinder 13A.
3B is installed, and the exhaust gas passes through the shower to remove dust.

A coating 9F is applied onto the incineration chamber 2 so as to cover the drum 9 except for both longitudinal ends of the drum 9. A flue 9F is formed between the coating 9 and the drum 9.
F communicates with the smoke exhaust section 6 in the incineration chamber, and
The operation of the deodorizing drying incinerator 1, which is composed of six or more components and is in communication with the chimney 9G installed upright on the cladding 9E, will be described.

The material to be incinerated 15 is put into the soba 11 and the sauce 11C is closed. When the drive l110 is operated, the screw conveyor 1
1B and the drum 9A rotate, the material to be incinerated 15 in the hopper 11 is pushed out into the drum 98, is raked up by the raking blades 9C, 9C, etc. in the drum 9^, and then falls. It gets swept up and falls.

By heating the incineration chamber 2 with the burner 4 prior to this, hot air enters the drum 9^ through the exhaust hole 7A. It also enters the flue 9F through the smoke exhaust hole 6^ and heats the drum 9A from the outside. As a result, the material to be incinerated 15 in the drum 9A is dried.

Next, if the intake blower 14 is operated and water is spouted from the nozzles 13B..., the odor generated in the drum 9^ will enter the Java pipe 13^ through the gas vent pipe 12. The dust and odor that come into contact with the fountain java dissolve in water and fall, and the gas is sucked into the blower 14 and enters the incineration chamber 2. Since the main components of odorous substances are combustible substances such as sulfides, the odor that enters the incineration chamber 2 is incinerated by the heat of the burner 4.

Further, as the drum 9 rotates, the material to be incinerated 15 in the drum 9A is dried, falls onto the incinerator 3 from the discharge port 9B, and is incinerated by the burner 4.

As described above, this deodorizing drying incinerator 1 has good thermal efficiency because it can dry the material to be incinerated, incinerate the odor, and incinerate the material to be incinerated with one burner. And it can be made small.

In addition, the heat in the incineration chamber enters the drum and is forced to circulate back to the incineration chamber via the gas vent pipe, so the heat absorption efficiency of the material to be processed in the drum is high over a certain period of time.

The drum has a flue around its outer periphery and is heated from the outside, so it is suitable for drying and incinerating minute substances containing a lot of water (for example, bean curd, sludge, etc.).

Since the partition wall 5 is installed at an angle above the incinerator 3, the smoke generated when the material to be incinerated is incinerated on the incinerator 3 does not go directly to the smoke exhaust section 6 (the blower Since the air is blown from 14), it enters the drum 9^, where it is removed by a dust remover and supplied with oxygen by a blower before entering the incineration chamber 2, where it is completely combusted by the burner 4 before it enters the chimney. It has the characteristic of being smokeless because it is exhausted to 9G.

In addition, odor substances are generally organic substances with a temperature of 700"C to 8
If the mixture is left in a hot environment of 00°C or higher for 0.3 seconds, the odor substance will be decomposed by the heat. However, when exhausting air, if the exhaust gas containing odors flows at a speed of 40 m/h, a 13 m long deodorizing furnace is required to retain it for 0.3 seconds, and a heat source and a 70 m long deodorizing furnace are required.
Although a furnace that can withstand temperatures of 0 to 800°C is required, this invention eliminates these problems at once. The propane gas used in the burner contains 20,000 ppm of organic matter.
Since this is mixed with a foul-smelling organic gas of about Ippn and burned, it has excellent deodorizing efficiency.

The degree of dryness of the drum can be adjusted by stopping or rotating the drum in reverse.

〔Effect of the invention〕

As explained above, the present invention has the following excellent effects.

(1) One unit has the functions of a dryer and an incinerator, and also has a deodorizing function, and has one burner, so heat management is easy and thermal efficiency is high.

(2) Since the heat and gas in the incinerator are forced to circulate through the drum and gas vent pipe, there is no wastage of heat and drying can be performed efficiently, and smokeless combustion can be achieved through complete combustion. .

(3) Odors are removed by combustion in the incinerator, so no special odor removal equipment is required.

(4) Since the dryer, incinerator, and dust remover are integrated, it can be downsized and can be easily installed in a small space.
