Description
Technical field
The invention belongs to waste processing arts, and in particular to a kind of garbage treating process.
Background technology
As Process of Urbanization Construction progress faster, increased population, Municipal Garbage Yield sharply increase, at present, the annual city rubbish in China
Rubbish yield is at 1.8 hundred million tons or so, it is predicted that 2030, Chinese MSW research produces total amount per year will be to 4.09 hundred million tons, entirely
In more than 600 a big and medium-sized cities of state, there is 2/3 to be absorbed among the encirclement of rubbish, the city for having 1/4 has not had good place heap
Put rubbish.In China, garbage disposal has become the thorny problem of urban construction and management.
Various regions domestic rubbish disposal is by the way of burning mostly, due to containing gas chromatography in house refuse, is burnt
The smog of burning pollutes air, harmful to human body and crops；Also using fill out hole bury by the way of handle life
Rubbish, but contain many kinds of substance such as plastics in house refuse, it cannot degrade for a long time in the soil, pollution is produced to soil;Again
It is classification processing house refuse, mainly passes through artificial mode, the thing larger to the plastics in house refuse, paper, metal class
Material is sieved, recycling.It can be seen from the above that the mode of existing processing rubbish is unfavorable for environmental protection, living environment is caused
Pollution, and the plastic substance in rubbish cannot make full use of, and refuse reclamation rate is low, and refuse classification effect is poor.
The content of the invention
The defects of the purpose of the present invention is overcoming the above-mentioned prior art, there is provided a kind of garbage treating process, which can
Rubbish is effectively sorted, and the material to sub-electing is handled, consume energy low and non-secondary pollution, and salvage value is high.
For this reason, the present invention provides a kind of garbage treating process, include the following steps：
（1）, rubbish 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 be transported to crusher carry out break process；
（3）, by the rubbish and step less than 50mm（2）Rubbish after middle break process is sent to magnetic separator and carries out magnetic
Choosing, sub-elects metal garbage therein；
（4）, by step（3）Remaining rubbish is sent into winnowing machine and carries out gravity separation after middle metal garbage separation, sub-elects
Sand particles and plastic garbage；
（5）, sandstone, cement, concrete additive package and water is mixed and made into construction material；
（6）, plastic garbage be sent into plastic crushing cleaning machine carry out break process, and by the soil on plastic garbage
Remove it is clean, then will it is broken after plastics washing, drying；
（7）, the plastics after drying are put into melting furnace, plastics are heated at 300-500 DEG C as low molecule fluid, will
Low molecule fluid cracks in pyrolysis furnace, and cracking temperature is 650-800 DEG C；
（8）, lysate be passed into fractionator be fractionated, condensed after fractionation, condensation obtains solid wax.
The garbage treating process is effectively separated rubbish, and obtained sandstone and waste plastics recovery are recycled,
Reduce pollution of the rubbish to environment, simple process and low cost.
Further, step（6）It is middle that plastics are dried using three-level drying roller, the drying in three-level drying roller
Temperature is followed successively by 100 DEG C, 100-115 DEG C and 115-100 DEG C of 90-.Three-level drying is divided into prebake, preliminary drying and heating
Drying, the temperature of prebake is 100 DEG C of 90-, and the temperature tentatively dried is 100-115 DEG C, and the temperature of heating, drying is 115-
100 DEG C, prebake is used to tentatively plastics be dried, and preliminary drying can remove most of steam in waste material, heating, drying
Plastics are further dried, and plastics are preheated into melting furnace.
Preferably, step（6）Cleaning agent is washed and be put into middle plastic garbage is put into service sink, passes through tertiary effluent
Wash, remove 99% impurity.
Further, by step（3）The metal garbage of middle acquisition is further sieved by screening mechanism, the size of sieve aperture
For 15-20mm, slag and metal derby are screened out, slag is sent into fine grinding in ball mill, then levigate slag is passed through magnetic separator
Obtain slag concentrate and tailings.Slag in metal garbage and metal derby are separated, then slag is processed,
Slag concentrate and tailings is obtained, the taste of slag concentrate is higher so that steel slag resource is fully used, and tailing can be used as manufacture
The raw material of cement, turns waste into wealth, and reduces the pollution to environment.
Beneficial effects of the present invention：This garbage treating process provided by the invention, simple in structure, cost is low, efficient,
Effectively rubbish is separated, without filling and burning, avoids environmental pollution, the sandstone isolated and waste plastics are carried out
Effective recycling, turns waste into wealth.
Embodiment
With reference to embodiment, the present invention is furture elucidated.
Embodiment：
A kind of garbage treating process is present embodiments provided, is included the following steps：
（1）, rubbish 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 be transported to crusher carry out break process；
（3）, by the rubbish and step less than 50mm（2）Rubbish after middle break process is sent to magnetic separator and carries out magnetic
Choosing, sub-elects metal garbage therein；Metal garbage further to be sieved by screening mechanism, the size of sieve aperture is 15-20mm,
Slag and metal derby are screened out, slag is sent into fine grinding in ball mill, then levigate slag is passed through magnetic separator and obtains slag essence
Ore deposit and tailing.Slag in metal garbage and metal derby are separated, then slag is processed, obtains slag essence
Ore deposit and tailing, the taste of slag concentrate are higher so that steel slag resource is fully used, and tailing can be as the original of manufacture cement
Material, turns waste into wealth, reduces the pollution to environment.
（4）, by step（3）Remaining rubbish is sent into winnowing machine and carries out gravity separation after middle metal garbage separation, sub-elects
Sand particles and plastic garbage；
（5）, sandstone, cement, concrete additive package and water is mixed and made into construction material；
（6）, plastic garbage be sent into plastic crushing cleaning machine carry out break process, and by the soil on plastic garbage
Remove it is clean, then will it is broken after plastics washing, drying；During washing, plastic garbage is put into service sink and washes and is put into
Cleaning agent, is washed by three-level, removes 99% impurity.
During drying, plastics are dried using three-level drying roller, the drying temperature in three-level drying roller is followed successively by
100 DEG C, 100-115 DEG C and 115-100 DEG C of 90-.Three-level drying is divided into prebake, preliminary drying and heating, drying, prebake
Temperature be 100 DEG C of 90-, the temperature tentatively dried is 100-115 DEG C, and the temperature of heating, drying is 115-100 DEG C, preliminary drying
Do for tentatively plastics to be dried, preliminary drying can remove most of steam in waste material, and heating, drying is further dried
Plastics, and plastics are preheated into melting furnace.
（7）, the plastics after drying are put into melting furnace, plastics are heated at 300-500 DEG C as low molecule fluid, will
Low molecule fluid cracks in pyrolysis furnace, and cracking temperature is 650-800 DEG C；
（8）, lysate be passed into fractionator be fractionated, condensed after fractionation, condensation obtains solid wax.
This garbage treating process provided in this embodiment, simple in structure, cost is low, efficient, effectively by rubbish into
Row separation, without filling and burning, avoids environmental pollution, and the sandstone isolated and waste plastics are carried out effective recycling,
Turn waste into wealth.
The foregoing examples are only illustrative of the present invention, does not form the limitation to protection scope of the present invention, all
It is to be belonged to the same or similar design of the present invention within protection scope of the present invention.
