Definitions
- the invention relates to a method for treating waste, in particular household waste, household-like waste and household-like commercial waste, and a device for carrying out such a method.
- the invention relates in particular to a method for treating waste, in which the waste is treated biologically or biologically and thermally, in particular composted, dried, intermediately comminuted and sieved.
- the composting is preferably carried out in one or more closed containers with forced ventilation.
- the object of the invention is to improve such a method and to provide an apparatus for carrying out such a method.
- this object is achieved by the characterizing features of claim 1.
- the sieve oversize fraction is sifted after the intermediate comminution, in particular in a zigzag sifter.
- paper and / or plastics in particular paper and / or plastic films, are separated.
- the invention enables plastics in such a pure weed out that these can be used materially, for example for the production of binders.
- the object on which the invention is based is achieved in a method of the type specified at the outset by separating the waste into a light fraction and a heavy fraction after the treatment described. This is preferably done by one or more air stoves. It is advantageous to first screen the intermediate shredded waste.
- organic constituents are separated from waste, in particular from domestic waste or from commercial waste similar to household waste, in a material purity which makes it possible to use these organic components thermally in biomass heating plants or power plants.
- the waste is preferably comminuted before the biological treatment.
- a further advantageous development is characterized in that the heavy fraction from the air sources is subjected to a preferably selective comminution followed by sieving.
- a device for carrying out a method for treating waste is characterized according to the invention by a classifier, in particular a zigzag classifier.
- the device according to the invention is characterized by one or more devices for separating the treated waste into a light fraction and a heavy fraction, in particular one or more air sources. It is advantageous to provide a screening stage for the intermediate shredded waste. Another advantageous further development is characterized by a pre-shredder for shredding the waste before the biological treatment.
- a further advantageous development is characterized by a preferably selectively operating comminution device for comminuting the heavy fraction from the air sources and by a sieving stage for subsequent sieving of the heavy fraction after the comminution.
- FIG. 1 A schematic flow chart for the method according to the invention.
- the waste is separated by sieving into preferably two material flows, namely an undersize fraction 14 and an oversize fraction 15.
- the mass flow of the undersize fraction 14 is fed to one or more air stoves 9.
- the stream of oversize fraction 15, ie the coarse grain stream or light material stream, is fed to a zigzag sifter 7, which is preferably pressurized with air.
- a coarse-grained, airworthy light fraction 8 is generated, which consists of paper and plastic films.
- This light fraction 8 is discharged from the zigzag sifter 7.
- the light fraction 8 is divided into paper and plastics.
- Paper is a high quality biomass fuel.
- the light fraction 8 can be separated into a high-purity plastic fraction and a high-purity paper fraction. In this way, a fuel is created that mainly consists of paper and thus biomass.
- the plastic fraction mainly contains thermoplastic films, which have to be melted down, for example, and which can be used in the liquid state as binders for thermosets or inert materials.
- the heavy parts ie the heavy fraction 17 from the air sources 9 and 10, are subjected to a selectively acting comminution 11 with subsequent screening 13.
- the shredded material flow is thus sieved, with all brittle parts having a smaller grain size than the elastic parts.
- the sieve passage of small parts forms a residual fraction 18, which then mostly consists only of mineral substance.
- a residual fraction 18 of mineral substance remains which is fed to the heavy fraction stream.
- the light fraction from the sieve stage 13, ie the sieve overflow 19 of the sieve stage 13, can be fed to an inferior fuel fraction.
- the screen overflow 19 can get into a fuel bunker in this way.
- small-grained, light and heavy parts are separated again.
- the small-grained, light parts together with the corresponding parts from the air source (s) 9 form the light fraction 20.
- the heavy parts together with the corresponding parts from the air source (s) 9 form the heavy fraction 17.
- the light parts 20 get into a fuel bunker. As mentioned, the light fraction 20 of the sieve overflow 19 is fed from the sieve stage 13. The light fraction 20 forms an inferior fuel fraction.
- the invention provides a method and a device for separating paper and plastics from residual waste, which is characterized in that after a bio-thermal drying, intermediate shredding, sieving and zigzag sifting, paper and plastic films are separated from the light material stream and the heavy fractions according to air sources are fed to a selectively acting shredding with subsequent sieving.
