Description
Technical field
The present invention relates to rubbish preprocessing technical field, in particular it relates to a kind of changing food waste pretreatment system and method.
Background technology
It is complicated system engineering that changing food waste process is disposed, and the link of its most critical is the pretreatment work of changing food waste
Skill.As the material of changing food waste contains the material of all kinds and state, such as oils and fatss, sandstone, plastics etc., including recyclable
The organic substance for utilizing and the inorganic debris that cannot be recycled.Therefore, need to carry out material in processing procedure first pre-
Process, to remove impurity removing and material is divided into water, oil and slag, subsequent treatment is carried out to water, oil and slag respectively again then.
The treatment effect of pretreatment is directly connected to effectively carrying out for follow-up anaerobism or aerobic composting process.Current pre- place
Science and engineering skill, concentration adopt the technique for first crushing, sorting afterwards, due to containing substantial amounts of plastics, vial, bone etc. in changing food waste
Material, brings a large amount of floating things and the grains of sand to subsequent technique after these materials are broken, causes line clogging and accelerates pipe wear,
Ultimately result in system operation failure.Wherein, general preprocess method includes：Garbage collecting and transferring car by changing food waste discharging to expect hole
The inside, the material in material hole is delivered to oppositely rolling roller crusher by screw machine to carry out unifying to crush, then defeated by screw machine again
Deliver to foreign substances separator to be sorted, wherein the foreign substances such as plastics with diameter greater than its lower end mesh size are sorted outward transport and fill out
Bury, diameter is then input in slurry temporary storage tank less than the slurry of its lower end mesh size, and the material in slurry temporary storage tank is conveyed
Solid-liquid separation is carried out in solid-liquid separating machine, its solid organic matters is transported in anaerobic fermentation tank, its liquid phase mixture then by
Oil-water separation is carried out in being transported to oily-water seperating equipment (such as disc centrifuge), detached waste oil is transported to biodiesel life
