Organic waste disposal device that improves usability of organic waste

The present invention relates to an organic waste treatment device that improves the reusability of organic waste for treating organic waste, etc. remaining after purifying food waste, livestock waste, or wastewater containing organic matter, using a method of drying and carbonization At the same time as waste treatment, the gas generated in the drying and carbonization process is recycled to reduce energy cost and improve the calorific value of the generated carbide. It relates to an organic waste treatment device that can effectively control the internal temperature of the device, thereby improving the utility of the generated carbide and increasing the reusability of organic waste.

In general, organic waste is a generic term for household waste generated in homes or restaurants, sludge generated at sewage/wastewater treatment plants, etc., and since these organic wastes contain a large amount of moisture and are easy to corrode and generate odors, landfill or incineration Research on treatment methods including

For example, a method of burying in a landfill has been proposed as a method of disposing of organic waste. However, the method of landfilling is practically prohibited in accordance with related laws and regulations as well as environmental aspects. There was a problem with the loss of

Accordingly, a method of incineration and carbonization of the organic waste has emerged, and the organic waste is incinerated at a high temperature to be treated, or to be discharged as carbide having an extremely low moisture content through a drying and carbonization process to convert the carbide into a thermal power plant. It is being used as an auxiliary fuel, coagulant, and infill soil.

However, the treatment methods for the incineration and carbonization of organic wastes are known to generate a large amount of harmful gases, as well as leachate from landfills, thereby causing a second environmental pollution problem. When it is dried and used as an auxiliary fuel, its use is restricted because of the odor and difficulty in transport. Although the carbonization method of the organic waste is environmentally friendly and excellent in reducing civil complaints, it has the disadvantage that excessive operating and facility costs are generated, and a lot of complaints are generated due to the generation of odors.

Therefore, it is possible to suppress civil complaints by removing dust and harmful gases generated in the drying and carbonization process by itself, and at the same time, it is possible to reduce maintenance costs by recycling thermal energy by burning carbonized gas, and to reduce facility costs by simplifying facilities. There is a need to develop an organic waste treatment device that can.

Hereinafter, with reference to the drawings, an embodiment of the organic waste treatment apparatus with improved recyclability of the organic waste of the present invention will be described in detail.

Referring to FIG. 1 , the present invention includes a dryer 100 , a carbonizer 200 , a hot air supply unit 300 , first and second blowers 610 and 620 , and a carbide storage 700 .

First, the dryer 100 is formed to extend in the longitudinal direction, the interior is hollow to receive a certain amount of organic waste, and a separate screw for moving the accommodated organic waste from one side of the dryer 100 to the other side. can

The dryer 100 agitates the organic waste and at the same time has the purpose of drying the moisture contained in the organic waste. A sludge feeder 101 for introducing organic waste into the dryer 100 may be further provided on one side of the dryer 100 . The sludge feeder 101 is manufactured by a rotary valve and an airlock valve method for blocking the inflow of air by cutting off the inner space and the outer space of the dryer 100, and uniformly supplies a certain amount of organic waste. The delivered organic waste is dried while moving from one side to the other along the inside of the hollow dryer 100 .

The carbonizer 200 is formed to extend in the longitudinal direction, and has a hollow interior so as to receive the dried organic waste from the dryer 100 . The carbonizer 200 pyrolyzes and carbonizes organic waste with high-temperature thermal energy, generates pyrolyzed organic waste (hereinafter referred to as carbide), and discharges it to the carbide storage 700 .

Referring to FIG. 6 , the carbonizer 200 includes a first carbonization tube 210 , a first screw 220 , a second carbonization tube 230 , and a hot air case 240 .

The first carbonization tube 210 forms a cylindrical tube shape with a hollow inside to receive the dried organic waste from the dryer 100 .

The first screw 220 is installed to rotate inside the first carbonization tube 210 to primary carbonize while stirring the organic waste. At this time, the interior of the first screw 220 is hollow and receives hot air into the hollow interior. As the first screw 220 is heated, the internal temperature of the first carbonized tube 210 is increased, and thus the thermal decomposition efficiency of the organic waste stirred in the first carbonized tube 210 may be improved.

The second carbonization tube 230 is formed in a cylindrical shape surrounding the outside of the first carbonization tube 210 , and receives organic waste that has been primarily thermally decomposed from the first carbonization tube 210 . The first carbonization tube 210 is installed to rotate inside the second carbonization tube 230 , and a plurality of stirring blades are formed on the outer surface of the first carbonization tube 210 .

As such, the carbonizer 200 may improve carbonization efficiency by secondarily thermally decomposing the dried organic waste.

In carbonization, when organic waste such as sludge is heated to a high temperature in an oxygen-free state, water and gas are generated and thermal decomposition begins. The carbide corresponds to the carbon-based residue from the evaporation of residual moisture and gas from the dried organic waste. Therefore, when heating the inside of the carbonizer 200, it is preferable to heat after blocking from the outside so that air does not flow into the carbonizer 200.
