Description

Resource recycling and extinction treatment apparatus using food waste {EXTINCTION DISPOSAL APPARATUS FOR RECYCLING RESOURCES OF FOOD WASTE}

The present invention relates to an apparatus for recycling and recycling resources using food waste, and more particularly, it is possible to easily separate the water and solids contained in the treated water generated when decomposing food waste using microorganisms, In addition to recycling the extracted solids as useful resources, the final by-products from which the food waste is discharged from the liquid fermentation process are subjected to centrifugation to apply solids in the discharged water containing the solids (SS) that were discharged from the liquid fermentation process to the sewer. The present invention relates to a resource recycling and destruction treatment apparatus using food waste that can be recovered and reused as a useful resource.

       In general, food waste is taken out of the house and collected in a simple collection place, and it is collected / transported and disposed of in a reprocessing facility. This has been taking

       In addition, food waste has accelerated to decay during the summer, especially in the summer, and caused liquid pollution, causing environmental pollution due to odors, pests, and leachate caused by bacteria. Wastewater has been dependent on dumping at sea, but since 2013, it has faced a total ban on dumping at sea.

       The prohibition of ocean dumping is not enough for the government to enforce regulations in the absence of high concentrations of wastewater treatment.

     In order to make food wastes recyclable, the drying method is being introduced. However, due to the nature of foods, odors such as soy sauce irons by salt and odor due to corruption have contaminated the living environment around the reprocessing facility, and the land price around the facility is falling. It is happening until now.

     Food waste treatment technology is very important for resource recycling and is divided into food waste treatment facility and emission reduction treatment facility. First of all, in order to be treated in a treatment facility, it is necessary to go to the discharge source → intermediate point transport → collection → treatment facility, where various technologies have been developed and implemented to recycle the treated products as resources. However, such a treatment method is complicated to process, considering the environmental pollution and economic feasibility, there is a limit to be utilized beyond the wall of 80% water content rate, the desorption liquid is dependent on the dumping of the ocean.

      In addition, dehydration and compression methods are technologies that have already been avoided due to environmental pollution due to wastewater and sludge generation, and the drying method requires excessive energy costs, and when it is dried, soy sauce stench odor caused by salt is contained and contained in the material. When dried moisture is dried or burned out, nutrients are destroyed, and dried products have been limited in use due to problems such as accepting atmospheric humidity due to saltiness and reducing them to food waste. In particular, when recycling as compost, food waste is legalized to mix only 10% of the total compost due to salt. Considering the long fermentation and ripening process, there is a problem that the area of the yard is overly large, and many problems such as odor generation and leachate generation by anaerobic fermentation, as well as pests caused by food and protein intrinsic ingredients are exposed. It became.

     In addition, when recycled as feed, food waste is only a single feed that can not be used as a compound feed, and the current drying method was not enough to use as a single feed. The feed dried by the convection heat drying method is being rejected by livestock farmers because it is difficult to automatically pay in the group breeding farm.

Since then, technologies such as combined sewage treatment and use of anaerobic (fermented) cattle and post-alternative energy have been developed, but this also lacks thorough clinical research on food waste. It has

     Recently, legislative technology development in the field of weight loss treatment facilities has been enacted for the purpose of activating drying technology, which also does not take into account food waste characteristics. In other words, deodorization devices have been developed to remove the natural smell of food waste and the soy iron odor that is inevitably generated during drying, but household products have too little throughput, and do not rot, and salts are diluted in water when washing dishes in the kitchen. Because of the minimal smell of soy iron, it has been used in installations and verandas rather than in indoor spaces, or because of frequent replacement of filters.

In addition, it is difficult to develop a grinder that can handle both ductility and stiffness due to the nature of food wastes. In the case of residues, high moisture content requires high energy costs for drying, and when the dried material is placed in an external collector, the collectors set the collection cost by the weight of the sheep, but the collection is delayed because the income is not right. As the collection is delayed, the vicious cycle that is reduced to waste again is inevitably repeated to accept air humidity due to salinity, and any deodorization due to inevitable humidity, oil, and seasoning dust during heating. Due to the bad odor that does not pass through the device, it is hard to install indoors. In this case, the company exposed problems such as uncontrollable handling of garbage cans.

As a device for extinguishing food waste using microorganisms widely used in the past, it is disclosed in Korean Laid-Open Patent Publication No. 1998-083736 (published date; December 05, 1998).

Disposal device of food waste using microorganisms disclosed in the Republic of Korea Patent Publication No. 1998-083736 has an outer case having an installation space therein and an outer case having an outer lid for opening and closing the case side inlet formed therein, The dehydration container accommodated inside the outer case and formed with a plurality of drainage holes formed along the wall surface of the predetermined height from the bottom surface of the dehydration container, and fermentation of the organic waste introduced into the dehydration container while remaining in the dehydration container. A porous mineral particle in which microorganisms having a size larger than a drain hole are cultivated, a dehydration container side lid for opening and closing a dehydration container side inlet of the dehydration container, and a shaft driven by a cutter driving mechanism and penetrating into the dehydration container. Grinding the organic waste that is put into the dehydration container It is accommodated inside the outer case of the cutter and the outer case, while forming an empty space between the dehydration vessel and surrounding the outside of the dehydration vessel, and communicates with the drain hole formed in the dehydration vessel to discharge the waste liquid discharged therefrom A dehydration liquid collection container having an intermediate drain pipe, a heater for heating organic waste remaining in the dehydration container to an appropriate fermentation temperature, and external oxygen are introduced into the outer case to increase the proliferation effect of aerobic microorganisms. Microorganisms are formed in the outer case so that the inlet, and the bottom surface of the induction container side of the dehydration liquid collection container is formed at a predetermined height, the microorganisms are cultured in the porous mineral particles in the dehydration container through the drain hole And a vent hole for supplying to the drain pipe and an intermediate drain pipe of the dehydration liquid collection container.

However, the conventional device for extinguishing waste food using microorganisms configured as described above has a circular spatula, such as leek, radish, cabbage leaf, etc., because the stirring blade is formed in a simple spatula shape without any function due to lack of technology. There was a problem that organic matter was hardly treated, and it showed the limitation of processing time and processing capacity of food waste because it did not care about the living environment of microorganisms, and the device was stopped due to overload because food waste was caught between the stirring blade and the stirring tank. There was a problem such as throwing away.

In addition, when decomposing food waste using microorganisms, there was a problem that the microorganisms were not effectively decomposed due to the devices manufactured without properly grasping the characteristics and proper environment of the microorganisms. There is a problem that the membrane is formed by the mucus composed of sugars, peptins and the like derived from the action to block the inflow of oxygen and kill the microorganisms.

In addition, the conventional food waste extinction treatment device is operated at a temperature lower than the temperature at which fat components such as pork oil (28 ~ 48 ℃) and tallow (beef oil, 36 ~ 50 ℃) solidifies, in the agitator tank and the outlet There is a problem that this phenomenon is worsened in the winter when the temperature is lowered to prevent the decomposition of other food waste, kill microorganisms, inhibit the smooth discharge, and solidified in the.

In addition, the conventional food waste extinction treatment device is too short, the microorganism is a living organism, so if continuously stirred and pulverized, without moving, but only a very limited digestion and decomposition of the activity is significantly reduced efficiency Not only that, there were various problems such as polluting the air because the gas discharged from the fermenter was discharged directly into the atmosphere.
