High speed drying device and drying method using same {A Fast Drying Device By Tire Waste Wastes Drying Method Thereof}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drying apparatus, and more particularly, to dry dry gas generated during incineration of waste in sludge, food waste, marine by-products, agricultural and livestock by-products, organic wastes, and sludge-drying apparatus, thereby The present invention relates to a waste fast drying apparatus and a drying method using the same, which directly reduce the fuel cost by drying the waste by direct heating.

In the meantime, sludge and food waste are dried by burning fuel (heavy oil, diesel oil, petroleum) and drying waste by combustion heat or by using steam generated by boiler as indirect heat source (paddle dryer, disc dryer, double Disc dryers, screw dryers, vacuum dryers, etc. treat waste.

Japanese Patent Application Laid-Open No. 10-170151 (published on June 26, 98) and Korean Patent Publication No. 99-11081 (published on Feb. 18, 2008) improve the thermal efficiency in drying the dried objects and remove harmful gases and odors generated. Drying device which removes heat and dust and harmful gas in the process of exhaust gas exhausted from the drying device to the exhaust port of the gas circulation path through the heat exchange part and the purifying part, but this drying method is waste tire like waste tire. The present invention relates to a method and a drying apparatus for economically drying waste such as food waste by burning dry gas generated when burning.

The drying method disclosed so far burns fuel (petroleum, diesel oil, heavy oil) at the time of waste treatment and dry the waste with the heat of combustion, so that the combustion chamber can be made smaller than waste tire dry and incineration facilities, Due to excessive operating expenses (fuel costs), it is difficult to operate in local governments or facility operators.

As such, the operating costs (maintenance costs) required for waste disposal are minimized, and the dry pollutant gas generated during the incineration of specific wastes such as waste tires is burned to minimize environmental pollutants, and the combustion heat of 1000 ℃ to 1300 ℃ is generated. The company has developed a drying method and apparatus for drying (processing) general organic waste (food waste, sludge, sludge).

In addition, the indirect drying method that uses steam generated from the existing waste incinerator is used, but the steam indirect drying method requires a long drying time, a large heat transfer area, and a high temperature. High pressure steam boilers should be used.

However, in reality, when raising the steam pressure to high pressure, there are many problems in the selection of equipment and materials that can withstand high temperatures and pressures.

Therefore, they have developed a drier that can handle waste with little operating cost.

An object of the present invention is to solve the problems (waste disposal cost) that arises in the drying device using the above-described fuel (petroleum, diesel, heavy oil) and the dryer drying using steam as an indirect heat source (waste disposal costs) It is a drying device that burns dry gas generated when treating wastes and heats the outside of the dryer directly to dry it. The drying device is equipped with a rotary paddle dryer inside the dry gas burning chamber.

In order to achieve the above purpose, the waste tire is composed of a dry gas that generates gas when burning the waste tire and a combustion chamber that burns the dry gas generated in the dry gas. A rotary paddle dryer is attached to the combustion chamber to transfer, stir and grind the waste. , Simultaneous removal and high-temperature combustion heat of 500 ℃ ~ 800 ℃ directly heat the outside of the dryer, the drying speed is fast and the drying efficiency is high.

In addition, the wet volatile organic matters generated during the drying process are supplied to the nozzle installed in the lower part of the combustion chamber so that the high temperature pyrolysis treatment results in the generation of odorous substances and the discharge of environmental pollutants.

In order to achieve the above object, the following description will be given based on the drawings.

In the case of treating (drying) organic waste such as sludge, food waste, marine by-products, agricultural and livestock by-products, most of them are indirectly dried by steam generated by burning fuels (petroleum, diesel, heavy oil) in boilers.

As such, the fuel cost in the drying takes most of the processing cost, and thus the present invention has been developed to minimize this.

Example 1

Among the organic wastes being discharged, in particular, various drying methods are used for drying food waste and sludge. However, when the wastes are processed using ordinary fuel (light oil, bunker C oil), the drying cost is excessive compared to the waste disposal cost. It did not fit.

However, incineration of wastes that can replace fuels was carried out by burning dry gas generated at this time, resulting in savings of over 80% of fuel costs. The durability of the equipment due to the high temperature was slightly decreased, but the drying time was very fast, and the exhaust gas was treated below the standard value.

Example 2

When organic waste was supplied to a rotary paddle dryer and dried, it was pressed onto the inner wall of the dryer. Due to the falling phenomenon, the thermal efficiency decreased and the carbonization was severe, but in order to prevent the thermal efficiency and carbonization, a scraper was installed to remove the waste stuck to the inner wall of the dryer.

As a result, the drying efficiency was very high, and carbonization was prevented.

In addition, the rotary roller and paddles are installed and the rotary furnace rotates to impact the waste attached to the dryer. The rotating paddles are installed at an angle of about 5 ° to 30 °. Dried.
