Description

A kind of garbage treating process

Technical field

The invention belongs to waste processing arts, be specifically related to a kind of garbage treating process。

Background technology

Along with Process of Urbanization Construction progress faster, increased population, Municipal Garbage Yield sharply increases, at present, the annual municipal refuse generation amount of China is at about 1.8 hundred million tons, it is predicted that the year two thousand thirty, Chinese MSW research produces total amount per year will to 4.09 hundred million tons, in more than 600 big and medium-sized cities, the whole nation, have 2/3 to be absorbed among the encirclement of rubbish, have the city of 1/4 there is no good place heap garbage。In China, garbage disposal has become the thorny problem of urban construction and management。

Various places domestic rubbish disposal is adopt the mode burned mostly, and owing to containing gas chromatography in house refuse, air is polluted by the smog of burning, and human body and crops is all harmful；The employing also having is filled out the mode buried in hole and is processed house refuse, but containing many kinds of substance such as plastics in house refuse, can not degrade for a long time in soil, produces to pollute to soil;Classification processes house refuse besides, mainly through artificial mode, the plastics in house refuse, paper, material that metal class is bigger is sieved, recycling。As can be seen here, the mode of existing process rubbish is unfavorable for environmental protection, living environment causes pollution, and the plastic substance in rubbish can not make full use of, and refuse reclamation rate is low, refuse classification weak effect。

Summary of the invention

It is an object of the invention to overcome the defect of above-mentioned prior art, it is provided that a kind of garbage treating process, rubbish can effectively be sorted by this technique, and the material sub-elected is processed, and consume energy low and non-secondary pollution, and salvage value is high。

For this, the invention provides a kind of garbage treating process, comprise the steps:

(1), rubbish is sieved by screening mechanism, screen out the rubbish less than 50mm and the rubbish more than 50mm；

(2), the rubbish more than 50mm screened out is transported to disintegrating machine and carries out break process；

(3), the rubbish after break process in the rubbish less than 50mm and step (2) is sent to magnetic separator carries out magnetic separation, sub-elect metal garbage therein；

(4), remaining rubbish feeding winnower after metal garbage separation in step (3) is carried out gravity separation, sub-elect sand particles and plastic garbage；

(5), sandstone, cement, concrete additive package and water are mixed and made into construction material；

(6), by plastic garbage send into and in plastic crushing cleaning machine, carry out break process, and the earth on plastic garbage is removed clean, then the plastics after broken are washed, dried；

(7), being put in fusing stove by the plastics after drying, plastics are low molecule fluid by hot melt at 300-500 DEG C, are cracked by low molecule fluid in pyrolysis furnace, and cracking temperature is 650-800 DEG C；

(8), being passed in dephlegmator by lysate and carry out fractional distillation, condense after fractional distillation, condensation obtains solid wax。

Rubbish is easily separated by this garbage treating process effectively, and the sandstone obtained and waste plastics recovery is recycled, and reduces the rubbish pollution to environment, and technique is simple, and cost is low。

Further, adopting three grades of drying rollers that plastics are dried in step (6), the baking temperature in three grades of drying rollers is followed successively by 90-100 DEG C, 100-115 DEG C and 115-100 DEG C。Three grades of drying are divided into prebake, preliminary drying and heating, drying, the temperature of prebake is 90-100 DEG C, the preliminary temperature dried is 100-115 DEG C, the temperature of heating, drying is 115-100 DEG C, prebake is for being tentatively dried plastics, preliminary drying can remove the most of steam in waste material, and heating, drying is further dried plastics, and plastics entrance fusing stove is preheated。

As preferably, plastic garbage being put into service sink washing by step (6) and puts into abluent, being washed by tertiary effluent, removing the impurity of 99%。

Further, being sieved further by screening mechanism by the metal garbage obtained in step (3), sieve aperture is of a size of 15-20mm, screens out slag and metal derby, slag is sent into fine grinding in ball mill, more levigate slag is passed into magnetic separator obtains slag concentrate and tailings。Slag in metal garbage and metal derby are easily separated, are then processed slag processing, obtain slag concentrate and tailings, the taste of slag concentrate is higher so that steel slag resource is fully used, and mine tailing can as the raw material manufacturing cement, turn waste into wealth, reduce the pollution to environment。

Beneficial effects of the present invention: this garbage treating process provided by the invention, simple in construction, cost is low, efficiency is high, is effectively easily separated by rubbish, it is not necessary to landfill and burning, avoid environmental pollution, isolated sandstone and waste plastics are carried out effective recycling, turns waste into wealth。
