DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention
Drops installed at the bottom of the incinerator in an incineration plant
This is related to a gas discharge device. [0002] 2. Description of the Related Art Conventionally, in a municipal solid waste incineration plant.
Aims to cool incineration ash from incinerators and discharge dust
And a dust discharge device is provided at the bottom of the incinerator.
You. That is, incineration ash from the incinerator falls into the water tank.
Is being processed. At that time, for example, while the incinerator is stopped
Japanese garbage broth (high BOD, about 10,000 ppm)
There are cases that come into (drop off) into the ruler. [0003] SUMMARY OF THE INVENTION However, the conventional
In the composition, measures for garbage broth (biological treatment
No action has been taken and therefore anaerobic
H_Two S, CH_Four , NH _Three Gas and generate odor
It becomes a problem. Furthermore, drainage water provided downstream of the water tank
The load on the processing device becomes large. [0004] Accordingly, the invention of claim 1 of the present invention.
Is to aerobically aerobically in the aquarium,
Provide a dust discharge device for incinerators that can perform OD processing
It is intended for that purpose. [0005] The above-mentioned object is achieved.
For the present inventionNoDust discharge for incinerator according to claim 1
The device is a dust discharge device provided at the bottom of the incinerator.
A diffuser is provided to diffuse air in the tank.Totoro
Provided an EM bacteria supply device to supply EM bacteria in the water tankWas
It is characterized by the following. Therefore, according to the first aspect of the invention, incineration is performed.
The incinerated ash from the furnace is dropped into a water tank, cooled, and then discharged.
It can be processed in the dust discharge device. This
In the case of oxygen, the oxygen from the air diffuser is
Supply), the water tank can be turned into an aquarium,
For example, while the incinerator is shut down, broth of garbage
Actively aggressive even if you are in a regular
And BOD-treated in an aerobic atmosphere. The result
H by anaerobic_Two S, CH_Four , NH_Three Gas generation
Can be prevented and odor can be reduced. Like this
It was installed downstream of the water tank by performing biological treatment in a tank
BOD load on wastewater treatment equipment can be reduced or BO
The D load can be zero (cut). [0007] [0008]further,EM bacteria are supplied by EM bacteria supply device
Organic matter in water by EM bacteria
In other words, the odor can be further reduced. [0009] BRIEF DESCRIPTION OF THE DRAWINGS FIG.
It will be described based on. The incinerator 1 has a waste
An inlet 2 is provided, and an exhaust gas outlet 3 is provided on the other upper side.
Provided to drop incineration ash from incinerator 1
A number of ducts 4 are provided. At the bottom of the incinerator 1
The dust removal device 10 to be provided has a water tank 11, and this water tank
The duct 4 group penetrates through a lid 12 that covers the upper part of the
The lower end of the duct 4 is open below the water surface 13. [0010] Exhaust air communicating with the upper space of the water tank 11
An exhaust fan 14 is provided in the exhaust line 14.
15 is provided, and the downstream of the exhaust line 15 is to the waste bunker
Has reached. The water tank 11 extends below the water surface 13 and above the space.
A circulation line 16 is provided in the circulation line 16.
A ring pump 17 is provided. The dust discharge device 10 has a water tank 11 inside.
A diffusing device 18 for diffusing air is provided. I.e. aquarium
Inside 10, a diffuser tube 20 having a number of diffuser ports 19 is formed horizontally.
A plurality (or singular) are arranged as
The proximal end of pipe 20 is connected to pipe 22 from aeration blower 21
ing. In addition, the dust discharge device 10 has a water tank 11
An EM bacteria supply device 23 for supplying EM bacteria is provided. sand
That is, the EM bacteria supply pipe 24 is penetrated through the lid 12, and the supply of the lower end is provided.
The supply port 25 is located below the water surface 13. The operation of the above embodiment will be described below.
Will be described. The incineration ash from incinerator 1 passes through duct 4
Drop into the water tank 11, where it is cooled and discharged.
Is processed. At this time, drive the blower 21
Oxygen is dissipated from the air diffusers 19 through the pipe 22
Water is evenly diffused (supplied) into the water,
The water tank 11 of the heat discharging device 10 is a tank. Further
Then, the EM bacteria are supplied into the water by the EM bacteria supply device 23.
I have. Therefore, for example, when the incinerator 1 is stopped
And the garbage broth passes through the duct 4 into the water tank 11
Even if you enter
BOD treatment can be performed in a temper atmosphere. Anaerobic as a result
By H_Two S, CH_Four , NH_ThreeTo prevent gas generation
Odor can be reduced. In addition, organic substances in the water
By being decomposed by bacteria, odor can be further reduced
You. Thus, the water tank 11 of the dust discharger 10 is
By performing biological treatment in a tank,
Can reduce the BOD load on wastewater treatment equipment
Alternatively, the BOD load can be reduced to zero (cut). In addition, oxygen
(Dissolved oxygen) concentration in the dust discharger 10 that supplied
Should be maintained at 1 to 2.5 mg / l (ppm).
And the limiting concentration is 0.2 to 0.5 mg / l (ppm).
You. In addition, the operation of the circulation pump 17
The activated sludge method (floating method) of biological treatment can be used.
The air in the water tank 11 is forced by the operation of the exhaust fan 15
Waste is discharged to bunker. [0016] According to the first aspect of the present invention, the dispersion
The oxygen from the gas generator is evenly diffused (supplied) into the water.
In this way, the water tank can be turned into a tank,
While stopped, the garbage broth enters irregularly into the aquarium
Even if it ’s coming, make it aggressive and aerobic
Thus, the BOD process can be performed efficiently. as a result,
H by anaerobic_Two S, CH_Four , NH_Three Prevent gas generation
Can stop and reduce odor. Like this
By carrying out biological treatment in a tank, drainage provided downstream of the water tank
BOD load on water treatment equipment can be reduced, or BOD
Load can be reduced to zero (cut). [0017]Also,Decompose organic substances in water by EM bacteria
Thus, the odor can be further reduced.
