Description
Skill dog field
The present invention relates to a kind of resource recycle and reuse method, be specifically related to a kind of changing food waste into resources and utilize technology.
Background technology
At present, domestic have the part city to begin to research and develop the technology of utilizing about changing food waste into resources.The method of domestic processing changing food waste has following several:
Utilize changing food waste to make feed at present, a kind of is biological method, utilizes biotechnology to make feed, its production process technology complexity.One must replenish the living beings auxiliary material in a large number, and the living beings auxiliary product quantities of replenishing is equivalent to the quantity of changing food waste usually, and its cost of collecting transportation living beings auxiliary material is very high.Its two, must utilize high temperature drying, its dry amount causes consuming more multipotency source greatly.
Another kind, direct drying method, its shortcoming of technology of utilization is now, one, domestic most of process all adopts electric heat supply or natural gas heat supply, and energy consumption is bigger than normal; Its two, mostly to institute's processing materials have size evenly, the volume of material requirement that equates of thickness, make process equipment need more extruding, conveying mechanism; Its three, at present nearly all equipment all adopts continuous mechanized technology, but because changing food waste has the material diversity, certain corrosivity is arranged, in case continuous mechanized is produced certain link and broken down, then stop production to overhaul completely is unfavorable for that production management reduces production efficiency on the contrary.
Present technology is not almost considered recycling in the production process to comprise the recycling of waste gas, waste water and other materials.
Summary of the invention
The production of above-mentioned technology mainly is to solve special thing with the common mode of thinking.The thinking of technology of the present invention is that reverse thinking is dealt with problems.One, the garbage sorting difficulty is difficult to letter sorting in the high changing food waste of moisture content, utilize mechanical efficiency low, so technology of the present invention is to act in a diametrically opposite way, is to sort later in drying; They are two years old, usually drying equipment is often at single variety and the more consistent material of shape, and to make changing food waste accomplish that this point certainly will sort extruding more earlier and carry, cost manpower and materials efficient is low, the heavy caliber enter material way that this technology adopted, make material not of uniform size can mix pan feeding, the beyond the region of objective existence feed is pulverized substantially outside the removal of impurities when discharging, and whole processing step is very simplified; Its three, technology of the present invention has also solved problems such as recovery heat energy and other waste water, waste gas, reaches cleaner production and energy-conservation requirement; Its four, common grease separation method is a kind of to be water-oil separating, a kind of is to squeeze from solid, all needs the branch several steps to carry out.And this technology is finished the grease separation and Extraction synchronously by utilizing its vapour, liquid, solid three phase separation state under same temperature.
Therefore, purpose of the present invention is to provide a kind of new changing food waste into resources recycling new method, reaches efficient, energy-conservation, low consumption, environmental protection, realizes the target of recycling economy.
The technical solution used in the present invention is as follows:
A kind of changing food waste into resources utilizes new method, comprises the steps:
