TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a garbage dryer for drying crushed garbage while being separated by a garbage separator.
[0002]
[Prior art]
Conventional garbage dryers have stored garbage in a drying chamber and agitated to dry the garbage or passed through the drying chamber to dry the garbage.
[0003]
[Problems to be solved by the invention]
Since garbage contains a large amount of water, when garbage is used as a solidified fuel or the like, it must be sufficiently dried.
However, in order to dry for a long time, a large drying chamber is required, and there is a problem in the installation space, and the fuel consumption increases.
[0004]
In addition, there is a problem with respect to environmental problems such as generation of pollution due to emission of harmful substances contained in the combustion gas into the atmosphere.
[0005]
In view of the above, the present invention can sufficiently dry garbage for a long time in a small installation space, consumes a small amount of fuel, and removes harmful substances contained in combustion gas to be released to the atmosphere. Another object of the present invention is to provide a garbage dryer capable of preventing the occurrence of pollution.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the garbage dryer of the present invention communicates with a primary combustion chamber having an exhaust pipe through multiple pores, and in a drying chamber filled with fine particles of a heat-resistant material, a multi-stage in a vertical direction. A tubular body having a screw conveyor built therein is provided inside which extends in the lateral direction, and each tubular body is formed integrally by alternately communicating an end with an end of an upper or lower tubular body, and The screw conveyor is arranged so that the forward path and the return path are alternated up and down.The uppermost cylindrical body is provided with a garbage inlet that communicates outside the drying chamber, and the lowermost cylindrical body is provided with a garbage discharge port that communicates outside the drying chamber. A feed means is provided between the primary combustion chamber and the cylinder for sending steam generated in the cylinder to the primary combustion chamber.
[0007]
Further, the garbage dryer of the present invention is characterized in that a secondary combustion chamber is provided in the middle of the exhaust pipe of the primary combustion chamber with a shower chamber filled with fine particles of a heat-resistant material interposed therebetween. It is to be.
[0008]
In the present invention having the above configuration, the hot air in the primary combustion chamber enters the drying chamber through the multipores and heats the fine particles filled in the drying chamber.
By heating the fine particles, the cylindrical body provided in the drying chamber is indirectly heated, and the garbage in the cylindrical body is dried.
[0009]
The garbage in the cylinder is pushed in from the garbage inlet and conveyed while being squeezed by the screw conveyor, so that the water contained in the garbage is separated in the cylinder. Then, the separated moisture is converted into steam by the hot air received by the cylinder, is sent from the cylinder to the primary combustion chamber by the feeding means, and is vaporized in the primary combustion chamber.
[0010]
In addition, since the cylindrical body is provided in multiple stages in the vertical direction, and the ends are alternately communicated vertically to form a single piece, the raw garbage is transported over a long distance, the drying time is also long, and in a small drying chamber, Even if there is enough drying.
In addition, the cylinder is not exposed to direct flames, and is indirectly heated, and the surroundings of the cylinder are filled with fine particles, which prevents deformation of the cylinder due to heat and keeps the fine particles warm. And saves fuel.
[0011]
Next, when the combustion gas in the primary combustion chamber passes through the shower room in the middle of the exhaust pipe, soot and the like contained in the combustion gas adhere to the fine particles filled in the shower room, and soot and the like appear.
In addition, the combustion gas is deodorized by water in the shower room to remove odors, is further burned in the secondary combustion room, is completely burned, and is released into the atmosphere, so that all harmful substances in the combustion gas are removed. Is done.
[0012]

It is a vertical side view of a primary combustion chamber and a drying chamber.
[0013]
In the drawing, reference numeral 1 denotes a primary combustion chamber, a drying chamber 2 is provided on the back of the primary combustion chamber 1, and the primary combustion chamber 1 and the drying chamber 2 are separated by a partition 3 having a multipore 3A. It is formed so that the hot air in the primary combustion chamber 1 can flow into the drying chamber 2 through the multipore 3A.
[0014]
An exhaust pipe 4 is provided above a side surface of the primary combustion chamber 1, and a primary combustion burner 5 is provided below a side surface of the primary combustion chamber 1.
The drying chamber 2 is provided with a thin rectangular body, in which a cylindrical body 6 extending horizontally in multiple stages (eight stages in the drawing) is provided horizontally, and the cylindrical body 6 has an upper end or an end of a lower cylindrical body 6. Are alternately communicated by a connecting portion 6A to form a single piece.
[0015]
The uppermost cylindrical body 6 is provided with a garbage input port 7 communicating with the outside of the drying chamber 2, and the lowermost cylindrical body 6 is provided with a garbage discharging port 8 communicating with the outside of the drying chamber 2.
Above the garbage inlet 7, there is provided a pressing cylinder 10 for pushing garbage introduced from the garbage inlet 9 into the cylindrical body 6.
A conveyor belt 11 for conveyance is provided below the garbage discharge port 8.
[0016]
Further, screw conveyors 12 are respectively built in the cylinders 6 of each stage. The screw conveyors 12 at each stage are arranged so that the outward path and the return path are alternately arranged vertically. The rotation of the motor 13 is transmitted to each screw conveyor 12 by the interlocking mechanism of the chain 14 and the sprocket 15, and the screw conveyors 12 rotate the same.
[0017]
The periphery of the cylindrical body 6 in the drying chamber 2 is filled with fine particles 16 such as glass or ceramic of a heat resistant material. The fine particles 16 have a size that does not escape from the multipores 3A of the partition walls 3.
[0018]

Next, in the figure, reference numeral 22 denotes a shower room, and the shower room 22 is provided in the exhaust pipe 4.
The lower part of the shower room 22 is connected to a water tank 24 via a bottom plate 23 having multipores 23A, and a submersible pump 25 is provided in the water tank 24. The water is sent to the upper part of the shower room 22 through the provided water pipe 26, and falls again into the water tank 24 from the multipores 23 </ b> A of the bottom plate 23 of the shower room 22 and circulates.
[0020]
The shower room 22 is filled with fine particles 27 such as glass or ceramics of a heat-resistant material.
Therefore, the combustion gas from the primary combustion chamber 1 passing through the inside of the shower room 22 from the exhaust pipe 4 removes soot and the like contained in the combustion gas to the fine particles 27 in the shower room 22 while adhering to the water. Thereby, the offensive odor contained in the combustion gas is also removed.
[0021]
Then, the combustion gas that has passed through the shower chamber 22 enters the secondary combustion chamber 28 through the exhaust pipe 4A, is burned again in the secondary combustion chamber 28, and any harmful substances contained in the combustion gas are removed. Released from 4B into the atmosphere.
In the figure, reference numeral 29 denotes a secondary combustion burner provided at a lower portion of the secondary combustion chamber 28.
