Definitions
- the invention relates to a method for treating residual waste, in which the light fraction is implemented by thermal processes and the Heavy fraction is subjected to a biological rotting or fermentation process.
- Residual waste usually comes from municipal, commercial or industrial waste and arises after the previous collection and recycling all material and biological components in waste. These substances are with the known, mutually different methods collected and a material or biological recovery. The rest of the rest as well as the remnants from The treatment plants for material and biological recycling form the Residual waste.
- the composition of the residual waste to be treated is similar to that mixed household waste, but has a lower organic content, however, an increased level of plastic waste.
- the invention is therefore based on the object of a method of the beginning to create the type with which the prescribed parameters for the depositing remaining components can be achieved.
- this object is achieved in that the biological rotting or fermentation process coming material of the heavy fraction an annealing treatment, preferably at a temperature of about 1600 ° C, is subjected.
- an annealing treatment preferably at a temperature of about 1600 ° C.
- the biological rotting or Fermentation process coming material before the annealing treatment by wind sifting of the remaining light materials This has the advantage that Substances that are not necessarily subject to the annealing treatment because are otherwise usable, the annealing process and thus the energy balance is not strain.
- the light materials separated by wind sifting can Light fraction are added prior to their thermal utilization, whereby the in the energy content contained in light materials can be used particularly well.
- the exhaust gases resulting from the annealing treatment can, if necessary, Purification, in the biological rotting or fermentation process, whereby the resulting exhaust gases in the biological treatment plant accordingly be worked up so that pollution of the environment by these exhaust gases is switched off.
- the gases can be used to cool the annealing material at the end of the annealing treatment introduced gases at the beginning of the annealing treatment to warm up the red-hot good can be used.
- FIG. 3 shows a basic diagram of the annealing treatment step.
- the residual waste generated is processed in a mechanical processing plant which hazardous waste and valuable materials are separated into a Light fraction and a heavy fraction separated.
- the light fraction which is thermally recyclable, is fed to a special incinerator.
- the high loss on ignition is used as an energy source and the carbon increases Burned carbon dioxide.
- the light fraction has a high calorific value and has one essentially constant composition, causing the operation of ecologically sensible and economically favorable incineration plants, e.g. after the principle of the circulating fluidized bed is possible.
- the heavy fraction coming from the mechanical processing plant is subjected to a biological treatment, where appropriate sewage sludge can be added.
- the biological treatment is a rotting or a Fermentation process.
- This biological processing plant is now connected as Another new process step that the biological rotting coming material after it has been screened and screened into a light and heavy fraction is separated, is further processed.
- the won light Fraction is the light fraction, which comes directly from the mechanical Processing plant for residual waste comes, mixed and burned there.
- the fraction falling through the sieve or coming from the air classifier heavy fraction is subjected to an afterglow step.
- the screening of the The product is passed through a sieve with a preferred mesh size of 15 mm.
- the afterglow is carried out in a special tunnel furnace, whereby However, the prerequisite is that the water content in the biological Treatment level emerging material is reduced to about 20 wt .-% and the maximum possible removal of all light materials is achieved by the wind classifier.
- the tunnel kiln is preferably electric Resistance heating elements heated to avoid an open flame in the furnace and thereby reduce the risk of fire.
- This tunnel kiln that becomes Treated goods heated to a temperature of about 1600 ° C. Then it arises a glass-like product, which after cooling accordingly can be deposited.
- the tunnel kiln is designated 1 in FIG. 3 and has one Resistance heating element 2 for glowing the material.
- the loading of the Tunnel kiln 1 takes place via a conveyor belt 3, which the goods over a Filling hopper 4 is placed on the conveyor belt 5 leading through the furnace. Of this Conveyor belt 5 then drops the product at 6 and delivers it to a landfill.
- the kiln 1 has a heating zone 7 and a cooling zone 8, which through a targeted air flow is achieved. This happens between these zones Annealing the good.
- a pump 9 the cooling air introduced at the end of the cooling zone 8 at the bottom of the kiln occurs through the materials to be cooled and turns out at 10 at the top led out of the oven.
- the line 10 then leads to the central area of the Heating zone 7, whereby the material introduced into the kiln 1 is heated.
- the warming gas led out of the kiln via line 11 is transferred via guided a heat exchanger 12, which cools via a fresh water line 13 is.
- the cooled gas emerging from the heat exchanger 12, which with condensate is mixed, is fed via a line 14 to a separator 15, the cooled air is introduced via line 16 into the cooling zone of the kiln 1, etc. in the direction of the product flow in front of the line coming from the pump 9.
- the cooling air is heated by the annealed material and exits via line 17 the cooling zone of the kiln and after the line 10 again in kiln 1, etc.
- the warmed up air which also contains volatile components and Water vapor is enriched, exits the furnace via line 22 passed through a separator 23 and from there via a line 24 one Cleaning station 25 fed.
- the cleaning station 25 consists of two Wash stages 26, 27, in which the pollutants entrained in the exhaust gas washed out or neutralized. The first wash stage works in the acidic area and the second washing stage in the basic area.
- the condensate coming from the separators 15 and 23, as well as that from the Heat exchanger 12 emerging fresh water is via lines 35 and 36 in the rotting plant 31 is supplied in order to control the moisture balance there and also to break down any pollutant particles that are carried along.
- the quantity flow diagram shown in FIG. 2 shows this in another form 1, but with the addition of the individual Branches of guided substrate quantities.
