Description

GARBAGE DISPOSAL / LIGNITE MAKING SYSTEM AND MANUFACTURING METHOD OF LIGNITE USING THE SAME}

The present invention relates to a system for processing food waste and lignite, and a method for producing lignite using the same, and more specifically, a food waste processing and lignite manufacturing system for completely decomposing and destroying food waste, and a food residue decomposed and extinguished using the same. It relates to a food waste treatment and lignite production system to produce lignite by mixing with and lignite production method using the same.

Food waste is increasing every year, and economic losses and environmental pollution caused by the disposal of food waste are becoming social problems. The best way to solve this problem is to prevent food waste from being discharged or to reduce the amount of food waste produced in our traditional food culture.

There are also social restrictions on the disposal of such food waste, which is prohibited by law because the food waste that is discharged has its own salinity and can acidify the soil.

Recently, there have been proposals to recycle food waste by feeding it, but most farms have avoided it because livestock eating these feeds suffer from various diseases. Therefore, methods for efficiently treating food waste have been studied in various ways, and methods for pulverizing food waste and fermenting or drying it into livestock feed are widely known.

Among these methods, livestock feed is difficult to use as livestock feed because it does not decompose various detergents, plastics, metals, shellfish and vinyl contained in excessive salt and food waste, and it is practical to classify these foreign substances. Difficulties follow

In view of these issues, among the proposed technologies, Korean Patent Application Publication No. 10-2001-0027616 includes a hopper, a foreign matter sorter, a pulverizer, a dehydrator, a distributor, a storage tank, a fermentation and a dryer, a sorter packing machine, and discharged from a restaurant. Disclosed is a food waste processing apparatus for recycling food waste including live residues as livestock feed.

However, the food waste processing apparatus may achieve a predetermined purpose in terms of processing food waste to produce livestock feed, but having only one grinder to reduce the particles to a size suitable for fermentation and extinction when crushing the food waste. There was a limitation, and it was equipped with a foreign matter sorting machine, but it had a problem of sorting foreign matters manually, and there was no specific configuration for removing odors generated during fermentation of food waste, resulting in a second environmental pollution caused by odors. there was.

In addition, Korean Utility Model Publication No. 20-0166104 includes a hopper, a crusher, a screw press, a vacuum dryer, a cooling device, a deodorizing device, and the like to crush and dehydrate food waste containing a large amount of water, and then vacuum in the same dryer. Disclosed is a food waste treatment apparatus producing high quality feedstock by drying or fermentation drying treatment.

However, this food waste treatment device also has only one grinder, which has a limitation in reducing the particles to a size suitable for fermentation and extinction when crushing the food waste, and does not include a foreign matter sorter so as not to sort out foreign matters contained in the food waste. Along with the problem of not being able to remove the odor generated during the fermentation of food waste, there is a specific configuration for removing the odor by microbial spraying during the crushing, sorting and feeding stages. There was a limit.

In addition, the Republic of Korea Utility Model Publication No. 20-0242257 has a combustion device for obtaining a heat source required to carbonize food waste or to remove water from the food waste, and the high temperature introduced from the combustion device installed on one side of the combustion device Apparatus comprising an apparatus including a carbonaceous apparatus for carbonizing dried food waste using combustion heat and carbonizing the food waste at a temperature of 700-900 ° C. for 3 to 5 hours; A manufacturing method is disclosed.

However, the apparatus and method for producing activated carbon using this food waste discloses that the activated food waste is carbonized, or dried and carbonized by removing moisture from the food, thereby producing activated carbon. Not only is there a lack of system configuration, but there is also a lack of specific configuration for the selection of foreign substances. There is a possibility that foreign substances may be mixed in the production of activated carbon, and only the apparatus and method for manufacturing activated carbon in which most components are made of carbon are disclosed. There was a problem that can not be prepared.

Accordingly, the technical problem to be achieved by the present invention is to crush the food waste to a size suitable for the fermentation and extinguish, to perform the foreign matter selection automatically, to remove the odor generated during the fermentation of food waste, and at the same time ferment the food waste It is to provide a food waste treatment and lignite production system for producing lignite by mixing the remaining food waste residues and subsidiary materials.

In addition, another technical problem to be achieved by the present invention is to provide a method for producing lignite using the above-described food waste treatment and lignite production system.
