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,
Particularly, the present invention relates to a drying apparatus which introduces hot air from an incinerator for incinerating combustible waste containing dried feces as a heat source for rapidly drying the combustible waste.

Conventionally, combustible waste, which has a high moisture content but can be incinerated, has been incinerated mainly in oil-fueled incinerators to prevent various types of pollution. The disadvantage of incinerating combustible waste is that the fuel cost increases significantly.

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 present invention aims to provide a drying device that improves incineration efficiency by drying combustible waste with a high rate of incineration and transporting the sufficiently dried combustible waste to an incinerator for rapid incineration. .

That is, Figs. 1 to 2 all show one embodiment of the present invention. First, in Fig. 1, (1) is a method for incinerating combustible waste containing dried animal or bird feces. This incinerator (1) contains dried incineration containing animal or bird feces, which is continuously transported by a conveyor device (6) consisting of a bucket-shaped chain conveyor, a Mataha belt conveyor, etc. An input port (2) for inputting easily combustible waste, a combustion chamber (3) for burning the combustible waste input from this input port, and a flue (4) for discharging the high temperature soot generated in the combustion chamber. It consists of a chimney (5) that discharges the air to the outside through the chimney.

(7) is a primary drying gutter placed near the incinerator (1), (8) is a secondary drying gutter placed near this secondary drying gutter (7); On both sides of the drying gutter (7), there are two types of combustible waste containing animal or bird feces to be dried, which are supplied to the upper part by the conveying device (9), from the incinerator (1). A blowing nozzle 0η having a blowing hole (lla) for heating and drying the combustible waste by directly blowing high-temperature hot air guided through the heat exchanger αQ of the gutter (8) for secondary drying; It is composed of a scraper device α having a scraping plate (13&) for scraping off waste further toward the electric feed roll, and an electric feed roll 03 that sends out a predetermined amount to the upper part of the secondary drying gutter (8). ing.

Next, on the back side of the secondary drying gutter (8),
2--A heat source having a plurality of heat dissipating tubes (10a) for drying by indirect heat exchange the combustible waste that is sent out in a predetermined amount from the drying gutter (7) onto the gutter by the feed roll threat and slides down. Exchanger αO@2 is installed. (To) is a cover that seals this heat exchanger strip, (17) is the spraying (10) nozzle αη of the secondary drying gutter (7), and the heat exchanger support of the secondary drying gutter (8). α9 is an electric fan inserted between the incinerator (1), which sucks high-temperature hot air from the incinerator (1) through the connecting pipe, and supplies it to the spray nozzle αη through the heat exchanger αO; This valve is attached to the hopper gantry provided at the bottom of the drying gutter (8) and supplies dried combustible waste to the conveying device (6) of the incinerator (1).

Since the drying device of the present invention is configured as described above, the high-temperature hot air generated in the combustion chamber (3) of the incinerator (1) is sucked by the electric fan αη, and the flue (4) → Through the pipe (G) → heat exchanger αQ → electric fan αη, −
Next, it is fed into the spray nozzle αD of the drying gutter (7). Therefore, the high-temperature hot air sent into the blowing nozzle (b) is blown through the many blowing holes (11a) onto the combustible waste having a high moisture content on the gutter, thereby gradually heating and drying it. The thus dried combustible waste with a low moisture content is scraped off by a scraper device α■, and is then applied to a predetermined amount by a feed roll Sho to a secondary drying gutter (
8) Drying is further promoted by exchanging heat with the heat exchanger α1 through which hot air flows while the air is sent upward and slides down, and is stored in the hopper (1).

As mentioned above, the second drying gutter (7) is used.

Since the high-temperature soot from the furnace is then blown through the secondary drying gutter (8), the ash contained in the soot will adhere to the combustible waste. This also contributes to pollution prevention by reducing the ash content of flue gas emitted outside the temple.
