Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying device for drying industrial waste that has a high moisture content but can be incinerated, filth, and combustible waste that includes animal or bird feces. Something,
In particular, the present invention relates to a drying device which introduces hot air from an incinerator for incinerating combustible waste containing dried feces as a heat source for rapidly drying the combustible waste. Combustible waste, which is expensive but can be incinerated, is mainly incinerated in an oil-fueled incinerator to prevent various pollution, but this combustible waste has an extremely high moisture content, Sudame had the disadvantage of significantly increasing fuel costs.

This invention was made with attention to this point, and the hot air from an incinerator that incinerates combustible waste containing dried animal or bird feces is guided into a drying device, and the water contained in the drying device is The purpose of the present invention is to provide a drying device that improves incineration efficiency by drying combustible waste with a high yield rate and transporting the sufficiently dried combustible waste to an incinerator for rapid incineration.

That is, Figs. 1 and 2 all show an embodiment of the present invention. First, in Fig. 1, (1) indicates that combustible waste containing dried animal or bird feces is collected. An incinerator that incinerates dried combustibles containing animal or bird feces, which are continuously conveyed by a conveying device (6) consisting of a packet type chain conveyor or a belt conveyor, etc. There is an input port (2) into which easily combustible waste is input, a combustion chamber (3) where the combustible waste input from the input port (1) is combusted, and a flue (4) where the high temperature soot and smoke generated in the combustion chamber are combusted. It consists of a chimney (5) that discharges the air to the outside through a chimney (5).

(7) is a primary drying device placed near the incinerator (tl), (8) is a secondary drying device placed near this secondary drying device (7); 7
) is a container 0 () having an input port (9) on the upper part of which is used to continuously input combustible waste such as animal or bird feces to be dried through the conveyor OQ; 5 double-pipe annular spray nozzles with different diameters for heating and drying the combustible waste by directly spraying high-temperature soot led from the incinerator (1) onto the combustible waste supplied in the container. ]) and a supply valve α field for supplying the dried combustible waste to a conveying device such as a belt conveyor of the secondary drying device (8) and heating and drying the combustible waste with a high moisture content. It consists of a chimney θ for discharging the flue gas, which has become humid and low temperature, to the outside. As shown in FIG. 2, the bottom of the annular spray nozzle θυ is provided with a downwardly directed multilateral spray hole (11a).

Next, the secondary drying device (8) is the secondary drying device (8).
7), the first and second transport devices (12a
) (12b), and both conveyance devices (12a) (12b)
) A straight pipe blowing nozzle θG with a triangular cross section directly blows the high temperature hot air sent through the annular blowing nozzle 0]) of the secondary drying device (7) onto the combustible waste above. As shown in FIG. 3, both conveying devices (12a) (121
+) are bored with a large number of opposing idiomatic holes Q5a). The θ force is inserted between the annular spray nozzle (lυ) of the secondary drying device (7) and the straight pipe nozzle 0υ of the secondary drying device (8), and is used to remove the high temperature soot from the incinerator (1). is suctioned through the connecting pipe 08, and the annular spray nozzle (h)
This is an electric fan that supplies power to lυ and 1α tube blowing time 1 nozzle θ0.

Since the drying device of this invention is configured as described above, the high temperature soot generated in the combustion chamber (3) of the incinerator is
It is sucked by the electric fan 0η and sent to the flue (4) → the connecting pipe θ01-shaped spray nozzle 0υ → the electric fan aη → the straight pipe spray nozzle θe. Therefore, the high-temperature hot air sent to the annular blow nozzle θ1) is blown from a large number of blow holes (11a) onto the high-moisture-content combustion waste in the container (11) and gradually blows it away. In addition, the high-temperature hot air sent into the straight pipe blowing nozzle 0 field is blown onto the combustible waste with a low moisture content on the conveying device 0 through a large number of air holes (15a), and the waste is heated and dried. do.

As mentioned above, the combustible waste which has been secondly dried by the second drying device (7) and then sufficiently dried by the second drying device (8) is transported from the hopper Oa to the incinerator +11.
The materials are sent to the transport device (6) by an appropriate means (transport device A) and are incinerated in the incinerator (1).

As described above, the drying device of the present invention uses the hot air of soot generated in the combustion chamber (3) of the incinerator (1) to dry combustible waste with extremely high moisture content in the primary drying device (7) and the secondary drying device (7). The dry combustible waste is sent to the incinerator (1) after being thoroughly dried by the drying device (8), which significantly reduces the amount of fuel oil used in the incinerator. Not only that, but drying and incineration can be carried out automatically, which greatly contributes to cost savings. In addition, according to the invention, due to its configuration, the secondary drying device (8) must necessarily be placed below the secondary drying device (7), which has the effect that the area occupied by the drying device is extremely small. . Furthermore, according to this invention, since the high-temperature soot from the incinerator can be blown directly onto the combustible waste, the ash contained in the soot will land on the combustible waste. This will reduce the amount of smoke and dust emitted by the city, and will also be donated to the city for pollution control. Also, - the above - secondary drying device (7) and conveyance device (secondary drying device (8)
If the combustible waste is housed in a single closed container (not shown) having a chimney, the temperature inside this closed container will be higher and the drying effect of the combustible waste can be improved. .
