Abstract
The invention which provides a comprehensive processing method of food wastes relates to the filed of comprehensive food waste resource utilization. A main process route of the method comprises the following procedures: carrying out solid-liquid separation on the food wastes, allowing the resulting solids to go through a bag breaker (for plastic package bag breaking), a magnetic separator (for magnetic substance separation), a vortex separator (for nonferrous metal substance separation), and a light substance separator (for separation of substances of paper, plastics and the like), and fragmenting; and mixing a mixed organic matter with the resulting liquid, fully stirring and heating, and separating out the organic matter, grease and the liquid. The grease can be used to produce biodiesel or chemical engineering raw materials; and the organic matter can be combined with the liquid to generate biogas, produce fertilizers, and produce protein forages. The method which allows the quantitative reduction, the harmlessness and the resource utilization of the food wastes to be achieved makes the resource recycle of the food wastes be realized, and has a popularization value.
Description
Technical field
The invention belongs to changing food waste into resources comprehensive utilization field, is a kind of changing food waste to be carried out sorting, collection, treatment process.
Background technology
Along with The development in society and economy and quickening of urbanization process, city changing food waste amount increases year by year.Because of characteristics such as its high-moisture percentage and easily biological-degradables; Bring an a series of difficult problem for traditional disposal options; As produce a large amount of percolates, foul gas etc., simultaneously, " hogwash fat ", " rubbish pig " phenomenon have become the pollution problem in the urban life; Serious threat people's normal life and healthy, the appearance of these problems has all been dealt with direct relation improperly with changing food waste.
At present, the process that adopts on existing patented technology and the market, there is certain problem in the degree difference, and the one, the technology imperfection, the 2nd, process route is numerous and diverse, and the 3rd, energy consumption is high, and the 4th, can not tinuous production.
Method of the present invention can be isolated high-quality solid, reach grease.As for final production biogas, protein feed, organic fertilizer and biodiesel, existing mature technique and technology can be selected for use according to the actual conditions of locality to get final product.
Summary of the invention
Main feature of the present invention is to carry out Separation of Solid and Liquid earlier and make the solid dehydration, and this method helps removing the impurity (like pop can, bowl, dish, plastics, big bone etc.) in the changing food waste, and is broken then; The liquid that Separation of Solid and Liquid is gone out carries out Hybrid Heating again, utilizes combination trap to isolate: solid, liquid and grease, and this is a key of the present invention; In this heating and separating; The one, energy consumption is little, and the 2nd, can changing food waste liquid phase grease and solid phase grease all be isolated, the 3rd, oil quality is good.This method has solved the problem that exists on present changing food waste treatment technology, the technology.
Process controllability of the present invention is strong, the generation cycle short, and resource recycling can be continuously, closed production, protects environment.
The technical method that the present invention adopts is following:
A kind of changing food waste method of comprehensive utilization may further comprise the steps:
(1) the changing food waste special-purpose vehicle is discharged to changing food waste in the airtight material storage container, as buffering;
(2) changing food waste in the material storage container is carried out Separation of Solid and Liquid, make solid holdup >=50% through carrying, compress, dewatering;
(3) be evenly distributed in the changing food waste after (2) processing on the conveyer, successively through bag-breaking machine (scratching plastic packaging bag), magnetic separator (sorting type of tapping a blast furnace material), vortex sorting machine (sub-electing the non-ferrous metal material), light materials separator (sub-electing paper, plastic substance).
(5) changing food waste after will screening is all broken, is broken into the mixing organic matter of even fine particle.
(6) will mix organic matter and squeeze into combination trap with the liquid that handle (2).
(7) through combination trap organic matter, liquid and grease are separated simultaneously, and be stored in respectively in the storage tank separately, simultaneously combination trap is heated.
(8) can be according to actual conditions production biodiesel and production biogas or organic fertilizer or protein feed.
(9) in the whole technology, deodoration system is arranged, each link is carried out chemical deodorizing handle.
Combination trap in the above-mentioned steps (7) is provided with buffering area, has Separation of Solid and Liquid, oil-water separating function and air supporting, solid squeezing miscellaneous function simultaneously.
In the above-mentioned steps (7), buffering area is equipped with agitating device, and mixing speed is 60rmp～80rmp.
In the above-mentioned steps (7), between 95 ℃～145 ℃, mode of heating is not limit to the combination trap heating and temperature control.
In the above-mentioned steps (7), isolated grease, moisture content≤2; Impurity content≤0.5, acid value (mgKOH/g)≤30.

Indicated the technology content in this process chart.
The practical implementation method
At first from the hotel, places such as restaurant, dining room are discharged into the changing food waste of collecting the material storage container with special-purpose vehicle, and close loam cake, prevent that foul smell from escaping.
Start conveying worm, the solid changing food waste after squeezing, is evenly distributed on the apron conveyor, realize Separation of Solid and Liquid, and make solid content >=50%.
Bag-breaking machine, magnetic separator, vortex sorting machine, light materials separator through install the apron conveyor top break plastic packaging bag earlier, again magnetic metal, non-ferrous metal, paper and plastics therefrom sorted out, and in the container of packing into, compression packing back export trade.
Solid changing food waste after above-mentioned operation gets into disintegrating machine and carries out fragmentation, is broken into the mixing organic matter.
To mix organic matter and isolated liquid then and squeeze in the lump and heat in the combination trap and stir, and go out organic matter and liquid through Separation of Solid and Liquid, organic matter is handled through squeezing and is squeezed into storage tank, and liquid is handled through air supporting, isolates grease.Liquid, grease are respectively charged in the storage tank separately.Accomplished the overall process that changing food waste is handled.
Biodiesel or industrial chemicals can be processed into grease according to the actual conditions of this area in enterprise, with organic matter and liquid combination processing biogas or organic fertilizer or protein feed.Really make changing food waste reach minimizing, innoxious, resource.
