Organic waste drying and feeder using incineration waste heat

The present invention relates to a device for drying feed organic wastes, and more particularly, to a high-speed dryer for drying organic wastes by incineration waste heat from an incinerator after crushing organic wastes, and to a waste drying / feeding apparatus using incineration waste heat. will be.

In general, with the increase of population, the acceleration of economic development, and the increase of national income, the standard of living of mankind is improved, while environmental pollution is accelerating. In particular, food waste, sludge from sewage and wastewater treatment plants, waste from marine processing plants, waste from agricultural and livestock processing plants, waste from food and paper mills, The increase in organic waste such as slaughter waste, sawdust, rice bran, livestock manure and other organic raw waste at slaughterhouses is the leading cause of environmental and water pollution.

It is well known that the generation of organic waste as described above causes direct harm to human life, such as generation of toxic odors, abnormality of pests, pollution of water sources due to leachate and waste water, and the like. Accordingly, as the environmental and water pollution have emerged as a major social problem, the desire for a pleasant environment has increased day by day, and efforts to treat waste have been studied in various ways.

As part of the efforts to dispose of the organic wastes described above, products made by fermenting wastes into artificial soils, composts, and feeds are actually distributed on the market, and further advanced researches are being conducted. The following describes a conventional example of the treatment of organic waste.

One example of a conventional method for treating organic waste is landfilling, which is associated with a number of problems due to landfill shortages, transportation costs, and enormous landfill costs. In addition, there is a problem that the water quality and environmental pollution due to problems such as leachate and odor.

On the other hand, it is the feed of organic waste that has emerged as an alternative when livestock farmers are expected to be difficult due to concerns about crop production due to the opening of the capital market, global warming, and El Niño, and the resulting increase in feed prices. Conventional organic waste feed methods include dry fermentation feed method and wet feed method.

The dry feed method of the conventional feed method described above has a low loss of organic matter and inorganic matter during fermentation, so that high-quality feed is possible, but there is a problem in maintaining the cost and storage capacity of the feed. On the other hand, the wet feed method has a simple structure and economical aspects, but there is a problem in that there is a high possibility of deterioration in the collection and transportation process and a bad odor occurs in the treatment process.

On the other hand, the method of incineration of organic waste not only consumes a lot of fuel and power costs, but also causes a problem of inducing air pollution by generating harmful gases during incineration.

As described above, the conventional method for treating organic waste is accompanied by problems of landfill problems, transportation costs, and enormous landfill costs, resulting in secondary environmental pollution such as leachate and odors. There is a problem that causes the generation of odor and harmful gases.

The present invention was devised to solve the above-mentioned problems, and the organic waste drying and incineration waste heat using a high-speed dryer and incineration waste heat to dry the organic waste pulverized by the incineration waste heat of the incinerator can reduce fuel and power costs. The purpose is to provide a feed apparatus.

Another object of the present invention is to produce a dry feed of less than 10% moisture content through a dryer to enable long-term storage, as well as to reduce the weight and volume to facilitate transportation and packaging.

The present invention configured to achieve the above object is as follows. That is, the present invention is a hopper for inflowing and storing organic wastes, a drying furnace for drying organic wastes, a transfer screw installed at a lower side of the hopper to transfer organic wastes into the drying furnace, and installed in place of a drying furnace in a transfer screw. A crusher for crushing the organic waste introduced into the drying furnace, a hot air blower installed at one side of the drying furnace to blow hot air into the drying furnace, and drying the organic waste pulverized by the crusher; Incinerator heat supply pipe connecting the incinerator and the hot air blower, a blower that scatters the dry matter dried by the hot air of the hot air blower through the negative pressure inside the drying furnace, a dust collector which collects the dry matter scattered by the blower, and It consists of a storage tank for storing.

At this time, when the calorific value of the incinerator is insufficient, a burner for supplying calories to the hot air may be further installed on one side of the hot air.

On the other hand, the above-described dryer is installed on the drive motor, the drive shaft driven by the drive motor, a plurality of horizontally installed and fixed in the transverse direction above and below the outer peripheral surface of the drive shaft to the end of each of the rotary blade and rotary blade to crush the organic waste flowing into the drying furnace It may be made of a secondary blade for crushing the organic waste introduced into the drying furnace is hinged to flow.
