Description

High-efficiency classifying and recovery processing technique for resource in the domestic waste

Technical field

The present invention relates to the efficient classification of resource in a kind of domestic waste (plastics, paper, metal) and recycle, organic matter reclaims compost or burning, the integrated conduct method of inorganic matter landfill.

Background technology

Understand according to the inventor, China's urban garbage disposal technology is summarized at present, and sanitary landfill method, composting process, burning method are arranged.Its main pluses and minuses are as follows:

1. sanitary landfill method

Landfill generally has air storage, fills out ditch and fill out modes such as hole naturally.Be the ground of the breeding of disease worm, germ, both be detrimental to health that contaminated air, water source have influenced city image again.Sanitary landfills be with rubbish at selected good place, behind the landfill certain altitude, add cladding material (eating rubbish with the protection against rodents worm spreads disease germs), allow it through long-term physics, chemistry and biological agent natural decomposition.This method is longer service time, and has wasted valuable land resource, has wasted recyclable resource in the rubbish, and underground water resource has been caused threat.

2. composting process

The garbage compost method is to utilize microorganism under appropriate condition the organic matter in the domestic waste to be degraded, and makes it to become stable fertile soil, solves the soil compaction problem.The garbage compost method has been kept the good circulation of nature material, has realized garbage harmless, resource substantially, turns waste into wealth.

But this technology of garbage disposal should be prerequisite with the refuse classification.Because from garbage disposal with utilize angle, quite complicated without the component of refuse of sorting, iff the way by mechanical grading, many harmful materials will enter soil along with composting production, thereby cause secondary pollution.

3. incineration technology

Burning disposal can subtract appearance significantly, save the landfill yard space, can carry out exhaust heat recovery power generation.But the recyclable resource of house refuse (plastics, paper) is just burned the significant wastage that has caused resource without sorting.And if the flue gas that the plastics burning produces is dealt with improperly and can be caused serious secondary pollution to atmosphere.Organic matter such as water content food with high is fabulous organic fertilizer after treatment in the house refuse, nor is suitable for burning.

If all said methods are to the processing of effectively classifying of the Recyclable in the rubbish, and simply use any processing method, all can cause the significant wastage and the second environmental pollution of resource.

Summary of the invention

The present invention is in the relatively more existing domestic rubbish disposal technology of analysis-by-synthesis, analyze on the basis of pluses and minuses in the prior art, the characteristics of taking all factors into consideration existing city house refuse treatment method and equipment propose the house refuse recovery comprehensive utilization processing method of the efficient sorting recovery in a kind of source of raising funds, sanitary landfills, burning, compost treatment and one.

For achieving the above object, this programme adopts following method to realize

1, manual screening: the explosive and the bulky objects that may contain in the rubbish are carried out preliminary sorting, with protection equipment and operating personnel's safety.

2, beater: break up the object that is wrapped in the refuse bag, the garbage energy of various compositions is evenly distributed on the belt conveyor.

3, belt conveyor: rubbish material is transported to next equipment.

4, wind-force grading machine: rely on wind-force that film, paper in the rubbish are separated with other heavy object, alleviate artificial separation labour intensity.

5, magnetic separator: be placed on the top of belt conveyor, when magnetic metal is adsorbed and is transported in the gathering-device through out-of-date meeting.

6, trommelling machine: bulky grain in the rubbish (greater than 70mm) can be separated and is transported to next procedure with granule (less than 70mm) object during the cylinder rotation and carry out different processing.The plastics that this equipment is mainly bigger with volume, paper separate with a large amount of food, silt, vegetation.

7, vibrating screener: mainly that organic matters such as the food of volume big (greater than 20mm), vegetation and volume is less (less than 20mm) silt, the glass of this equipment separates.

8, storage bin hopper: a kind of semi-enclosed container, the automatic discharge mouth is arranged, be used to store the rubbish of handling through final.

9, artificial separation feed hopper: a kind of autofeed device, to artificial separation system even feeding, be convenient to workman's sorting.

10, artificial separation system: by manually waste paper in the rubbish and plastics being carried out meticulous sorting and grouping.Be recovered the surcharge of resource with raising.Semiclosedization carried out in the working region, and exhaust system is arranged, to improve operator's working environment.

11, compressing baling press: paper after the sorting and plastics are compressed packing automatically, be convenient to transportation.

12, refuse pressing and loading machine: rubbish compressed subtract appearance, get rid of the sewage in the rubbish.

13, organic matter and vegetation are transported to the dung yard compost treatment.

14, inorganic matter is transported to landfill yard sanitary landfills processing.

15, waste paper, plastics, metal carry out the resource recycling.

This programme is realized the high efficiente callback regeneration of recyclable resource in the house refuse, has avoided the secondary environmental pollution that does not thoroughly cause because of refuse classification.
