This preprocessing device can with long fibers such as the jumbo size impurity among the kitchen garbage and hair, cloth simultaneously and the organic materials accomplish the separation, avoid the impurity in the material to stop up equipment such as breaker, satisfy kitchen garbage treatment process to the requirement of feeding material, simultaneously with the impurity dehydration in the device that produces, the minimizing of realization impurity.
Description
Technical field
The utility model is related to a kind of utensil garbage pre-processing device, and in particular to a kind of kitchen garbage sorting pretreatment dress
Put.
Background technology
Kitchen garbage is swill, raffinate and the waste grease produced during food processing, catering service, food and drink
Discarded object, its 90% composition is swill, including starch and grease, rice and flour group food remnants etc.；Other 10% into
It is divided into impurity, including polybag, vial, milk box, big bone, pork skin etc..China kitchen garbage concentrate be thrown into residential block,
Restaurant and the dining room of each enterprises and institutions, its complicated component can not carry out the material of biological treatment containing metal, plastics etc..Meal
Kitchen garbage disposal is improper to easily cause rugged environment pollution, and easily grows the harmful substances such as pathogenic microorganism, mycotoxin；Together
When, nutrition content enriches in kitchen garbage, with larger resource potentiality, therefore using suitable processing method to meal
Kitchen rubbish is processed, and effectively reduces kitchen garbage surplus and fully reclaim the energy being just particularly important.
Existing Food waste treatment method is mainly including burning, landfill, aerobic compost, feed method and anaerobic digestion etc..Meal
Kitchen waste incineration is typically cooperated with consumer waste and together burns；Kitchen garbage is high due to moisture content, therefore calorific value is relatively low, is burnt
Need to add combustion-supporting material during burning, while moisture content is too high kitchen garbage burning can be caused insufficient, in combustion may
Bioxin can be produced to pollute air；Landfill is a kind of conventional process that early stage processes kitchen garbage, easy with processing method, is thrown
The advantages of providing relatively low；And the major defect for filling is big floor space, garbage degradation speed is slow, while a large amount of diafiltrations can be produced
Liquid contaminated soil and underground water；Aerobic compost is the air duct slats for coordinating supply good using the organic matter degradation function of microorganism
Part is degraded to organic matter, at the same reduce msw water content, the advantage is that technique is relatively easy, investment and operating cost compared with
Low, the weak point of aerobic compost lies also in floor space greatly, and degradation effect of organic compound is low, and easily produces foul smell to cause
Atmosphere pollution；Feed method is also a kind of method of disposal of early stage kitchen garbage, intends higher using the content of organic matter in kitchen garbage
The characteristics of it is recycled, having a disadvantage in that cannot solve the problems, such as kitchen garbage homology, may be by kitchen garbage
In the pathogen that carries and heavy metal etc. be delivered in the middle of human body by the cumulative effect of food chain, with certain harm；Detest
Oxygen digestion method is that organic matter is degraded under anaerobic, and organic removal rate is high, and can produce clean energy resource biogas,
The energy in kitchen garbage is effectively reclaimed, is that current kitchen garbage processes a kind of widely used method.Anaerobic digestion is only capable of
Except the organic matter in kitchen garbage, and the operation normal for anaerobic digester system of large scale inorganic impurity has certain influence, because
This kitchen garbage needs to be pre-processed before anaerobic digester system is entered.
Kitchen garbage pretreatment mainly includes that broken bag, sorting and material are broken.Wherein sort effective for biomass energy
Recycle particularly important.For the labile organic compound included in kitchen garbage and large scale non-degradable or difficult degradation
Impurity, can obtain starch, rice and flour group food remaining by effectively sorting, separate remaining large scale debris (such as vial,
Big bone etc.), the long fibre such as polybag and hair cloth.The treatment effeciency of subsequent anaerobic digestion workshop section can not only be so improved,
The materials such as bulk debris and long fibre are avoided to cause to wear and tear or block follow-up equipment simultaneously.The sorting of kitchen garbage is used as pre- place
Important step during reason not only can significantly reduce the difficulty of subsequent processing units, treatment effect be improved, while being
The recycling of kitchen garbage provides good thinking.The current refuse classification degree of China not enough, is mixed into kitchen garbage
The debris such as substantial amounts of polybag, cloth, tableware and glass container, debris type is more, larger to subsequent treatment workshop section equipment loss.
Current screening installation is processed primarily directed to the large scale impurity in kitchen garbage, and thing is completed using equipment such as rotary screens
Material is separated with impurity.This equipment has preferable centrifugation to large-size impurity, but it is difficult in removal kitchen garbage
Easily there is the winding of bag axle so that occluding device in long fibrous materials, these debris, therefore effective for the screening installation of kitchen garbage
It is less.
