Hybrid recycling system for organic waste into fuel and maturity {HYBRID RECYCLING SYSTEM FOR FUELIZION AND FERMENT OF ORGANIC SUBSTANCE}

The present invention relates to a hybrid resource system for converting organic waste into fuel and maturation, and in particular, organic waste such as sludge, manure, chicken meal, food waste, etc., is dried in a short time with high-temperature hot air without mixing additional additives, but discharged from the dryer. By recovering the exhaust gas containing steam generated and reusing it as a drying heat source, energy used for drying is drastically reduced, and organic waste can be easily controlled and manufactured according to demand as fuel or composted soil, thereby reducing a large amount of organic waste. The present invention relates to a hybrid resource system for converting organic waste into fuel with improved structure that can be quickly disposed of, reducing carbon emission, and embedding it in maturity.

Along with the increase in livestock production due to the increase in meat consumption worldwide, a large amount of organic waste is generated due to the increase in the amount of sewage treatment in the lives of many populations, and when such organic waste is landfilled, it causes soil contamination by leachate and secures a landfill. In the case of incineration treatment, the problem of causing environmental pollution and enormous fuel costs are required, and the useful resources contained in them are discarded. Therefore, the useful resources from organic wastes are efficiently treated and turned into resources. have.

In particular, organic wastes such as sludge, food waste, livestock manure, poultry, organic wastes discharged from agricultural and aquatic products processing processes, organic wastes discharged from food processing processes, and wastes discharged from slaughter factories are polluted with high moisture content. Due to the high concentration of the substance, there was a difficulty in treatment.

As a method of recycling such organic waste, a method of recycling as fuel by drying and carbonizing is disclosed, for example, in Korean Patent Laid-Open Publication No. 10-2008-0110969 (published on December 22, 2008). In order to carbonize the carbides that pass through the organic matter dried by the high-temperature hot air in the drying furnace through the heat medium pipe provided in the center of the interior in an oxygen-deficient state, the heat medium pipe is attached to the carbonization furnace at an appropriate angle to heat the heat medium pipe to heat the heat medium pipe. There is disclosed a carbonization furnace configured to indirectly heat and carbonize the carbide passing through the inside of the furnace, and to be guided by a manned blower installed at the rear end to transport the carbonized product together with gas toward the outlet of the heat medium pipe.

In addition, as an example of other treatment of organic waste, in Korean Patent Registration No. 10-1597765 (registration date February 19, 2016), sewage sludge is input from the outside and temporarily stored, and the sludge stored in the lower part is discharged quantitatively. A raw material storage hopper to which a transfer pump is connected; A dryer in which a fixed amount of sewage sludge is introduced into the interior by the sludge transfer pump, and an electric heater is installed on one side to heat outside air to supply it to the interior; A simmering machine in which the dry sewage sludge discharged from the dryer is supplied to the inside, has a cylindrical shape in a horizontal direction, and is rotated around an axial center so that the dried sewage sludge introduced into the inside is ripened from the inside; A crusher for receiving and pulverizing the sludge discharged from the composting machine; A post-heating tank for receiving the composting sewage sludge pulverized in the grinder, receiving heated air from the outside to stabilize the composting sewage sludge, and discharging the internal air to the atmosphere through the silo exhaust pipe; A pellet molding machine for molding the sewage sludge stabilized in the post-heating tank into pellets; The pipe is connected to the post-heating tank and is configured to selectively receive and store the sewage sludge discharged from the post-heating tank.The discharge port is connected to the dryer and the pipe to supply the stored fermented sewage sludge to the dryer and supply it from the raw material storage hopper inside the dryer. Disclosed is a sewage sludge maturation facility comprising a return hopper to be mixed with the sewage sludge to be mixed.

However, in the above-described conventional technology, organic wastes are dried and carbonized to be used as fuel in order to be recycled as fuel with separate complex structures to treat organic wastes, or composted as composting facilities. However, the demand for compost due to seasonal factors In the event of a decrease in demand or a decrease in demand due to the circumstances of the solid fuel consumer, difficulties arise in the treatment of products produced by organic waste treatment, and the operation rate of the facility decreases, resulting in loss of operating costs. It was difficult to efficiently treat the generated sludge because there is no facility capable of implementing the immature process together and operating by changing the treatment method according to demand.

In addition, when the amount of organic waste is increased, there is a problem that the cost burden for facility expansion accordingly and the treatment cost due to external consignment treatment are excessively generated. Organic wastes have high moisture content even after dehydration and have poor breathability.In order to embezzlement, a moisture control material such as sawdust or rice hull is mixed to reduce the moisture content to a certain amount to proceed with the fermentation process, and an additive such as a separate moisture control material is added. There is a problem that costs are incurred and time-consuming to treat a large amount of organic matter.

Fig. 2 is a detailed view of the fueled dryer.
3 is a detailed view of the maturity period.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing embodiments of the present invention.

In FIG. 1, the hybrid resource conversion system for organic waste into fuel and maturity according to the present invention includes a dryer 100 for first drying organic waste, and a first drying organic waste with a moisture content of about 40-50% from the dryer. The distribution conveyor 150 for distributing the, the primary dried dry matter supplied from the distribution conveyor 150 to a predetermined moisture content, for example, to a fuel dryer 200 for drying within 10%, the distribution conveyor 150 The simmering machine 300 that embodies while supplying air to the primary dried dry matter supplied from, the dry matter cooler 400 that cools the dry matter discharged from the fueling dryer 200 and discharges it to a molding machine, and the fueling dryer 200 A dust collector 500 for removing dust from the exhaust gas generated and discharged from the dust collector 500, and a scrubber 600 for cleaning and discharging the exhaust gas discharged through the dust collector.

In addition, in the deodorization furnace 120, a part of the exhaust gas generated from the simmering machine 300 is supplied to remove odor, and the waste energy contained in the exhaust gas of the simmering machine 300 is supplied to the dryer together with outdoor air. It is possible to save energy for forming hot air used in the dryer by using it to form hot air that is used in the dryer.

The distribution conveyor 150 selectively supplies the primary dried organic waste supplied from the dryer 100 to the fuel dryer 200 or the maturing machine 300. For this, for example, by selectively rotating the screw installed inside, the first dried organic waste is distributed and supplied to the fuel-burning dryer and the simmering machine, so that the first dried organic waste is selectively treated as solid fuel or compost as needed. This enables efficient management of the facility operation rate.

As the composting machine 300 formed as a drum rotates, the first dried organic waste supplied from the distribution conveyor 150 is fermented and moved to the discharge section. At the inner end of the discharge unit, blades 310 protruding radially inward and spaced apart from each other are provided to complete the maturation. A part of the moved organic waste is conveyed by the blade to the conveying member 320 having a spiral conveying path installed in the central part to the input part of the simmering machine, and the remaining part is discharged. The gas generated in the incubation period 300 is partially supplied to the deodorization furnace 120, while the rest is re-supplied to the incubation unit through the incubation blower 350 together with the outside air, thereby properly adjusting the temperature required for the incubation process in the incubation period. You will be able to keep it.

The conveying member 320 conveys the organic waste charged inside by the blade 310 to the input part of the sub-tank drum, and this process is performed at about 80° C. for the organic waste that is dried in the primary drying and charged to the incubator. Since it is discharged at a high temperature, it is difficult for the fermentation microorganisms to survive at this temperature, so that the fermentation is completed and part of the discharged compost is returned to be first dried and mixed with organic waste flowing into the fermentation period, thereby lowering the temperature. In addition, it is to increase the efficiency of maturation by allowing the microorganisms held by the maturing soil to proliferate.

Allows the efficiency to be improved.

Wastes of a certain size or more in the porous body 220 are pulverized by the pulverizer 210 in the process of repeating lifting and dropping by rotation of the fuel dryer 200 to reach the discharge portion of the fuel dryer. It is moved and the drying is completed and discharged to the dry matter cooler (400). Therefore, waste with large particles is not discharged, and it is possible to prevent the particles from being discharged in a dry state.

In the dry matter cooler 400, the dry matter of about 80°C, which has been dried to a moisture content of 10% or less in a fuel-burning dryer, must be cooled to a temperature that does not ignite, and for this purpose, it is cooled by the chiller 420 to the outer jacket part 410 and circulated.
