Definitions
- the invention relates to a method and a device for degassing, gasifying, burning and melting down waste and melting down solid residues, for example from domestic waste incineration plants, using waste as an energy source.
- the aim of the invention is to contribute to the relief of the environment. Its task is to specify a process for the effective inerting of slag, fly dusts, kettle ash and similar toxic substances and to create a device with which this process can be carried out.
- the material which is condensed and binds environmentally harmful substances in accordance with the inventive process is said to have a landfill form which is harmless to the environment (for example as a TVA inert residue according to the Swiss requirements of the Technical Ordinance for Waste) or is to be used instead of being disposed of for a useful purpose can.
- slags, dusts and boiler ash can be melted down solely by the energy content of the waste.
- the heavy metal compounds are immobilized, the glow loss is reduced to a minimum, the organic hydrocarbon compounds are reduced below the current detection limit and the specific volumes are greatly reduced.
- the basic idea of the invention is that instead of a complete incineration of waste, as has been sought up to now, only a substoichiometric carbonization of the process material is carried out beforehand in a low-temperature unit and then using the sulfurized materials or gases obtained in a high-temperature unit, complete combustion (for example in a rotary kiln) is carried out with subsequent slag liquefaction.
- the material remaining from the charring contains more combustion energy than the usual, burned-out residues and can be fed to a slag liquefaction process in the high-temperature unit, for example a rotary kiln. Part or all of the energy obtained by the gasification can be supplied to the slag liquefaction in gas form, so that the process can be controlled or regulated in a relatively simple manner.
- the end product of the process is a completely burned-out, liquefied slag that can be solidified in any form.
- Figure 1 shows schematically an overall system according to the invention, the waste-operated reactor with boiler and flue gas cleaning. The inventive method and also the essential parts of a device according to the invention can be discussed in this reactor.
- FIG. 2 shows the temperature profile in the reactor, measured in a test facility.
- FIG. 3 shows a diagram of the course, for example, of an addition of foreign matter for melting into the slag, here it is recirculated filter dust from our own plant, but it can also be foreign matter from other plants.
- FIG. 4 shows an example of the composition of the residual materials from a ton of waste (Vehlow literature).
- the reactor according to FIG. 1 is constructed using tried and tested plant components available on the market. In terms of process engineering, the components are coupled and connected in series so that the desired process can be carried out.
- the reactor points in the process direction, that is from left to right, the essential parts of the device: a feed point 1, for receiving the process material with devices for placing it on the smoldering grate (for example a feed grate); a generator 2 in which, with a u ⁇ terstoichiometric air supply, garbage garbage as an energy source or is gassed;
- the following essential equipment parts are present: a feed grate 3, nozzles 4 and addition devices 5 and 6; then follows a rotary kiln 7 with a gas / air hood 8, for the combustion of the generated generator gases and for the burning out and melting of the slag; this is followed by an afterburning chamber 9 with an addition device 10, for example air supply for lingering and afterburning still combustible parts and then an empty draft for the flue gases to be discharged
- the waste is conveyed to a feed grate via a feed device in a generator. Partial degassing and gasification and partial combustion take place here in a substoichiometric environment.
- the garbage is soaked and preheated. Since the processes in the generator (grate), in contrast to the most widespread grate systems, with much smaller amounts of air, especially with a smaller amount of underwind resp. smaller (substoichiometric) excess air, much less so-called "hot combustion nests" (hot spots) are formed in the micro or local area. This causes a strong reduction in NOx emissions (probably 50% -70%).
- the rotary kiln is connected to the generator for melting its own and foreign substances into the slag.
- a transition of the generator to the rotary tube is well distributed into the air under controlled conditions Rotating tube injected.
- foreign matter, recirculated dusts, dusts and slag from other plants and so on can also be abandoned.
- a combustion of the carbonization gases generated in the generator and a burnout of the solid feed material then occur.
- the temperature in the rotary tube is raised above the slag melting point and the entire solids (self-slag and foreign substances) are liquefied.
- the circulation of the slag in the rotary tube leads to thorough mixing, homogenization and good burnout.
- the slag flows out of the slightly inclined rotary tube into a pre-cooler and then into a detoxifier.
- the reactor can be equipped with the gas cleaning components currently on the market, such as dust filters, laundry, denox and dioxin separation.
- these components can be designed for * significantly lower gas volume flows compared to conventional waste incineration plants. Since the final temperatures of the combustion process are lower in a standard system than in the process discussed here, correspondingly larger gas volumes result. For this reason, in the method according to the invention Efficiency of the plant higher than with conventional waste incineration plants.
- Plants of this size cannot simply be set up on a trial basis or existing plants can be converted on a trial basis.
- the trials were not pre-sorted and shredded for the trials. In any case, it would make sense to separate certain fractions such as metals.
- the filter dust was added as recirculate via a specially made, water-cooled lock construction, which was attached close to the rotary tube (feed point 6, FIG. 1).
- the filter dust was introduced into the system in batches. During a certain period, an average of about 10%, later 20% of the amount of waste given during the main test was put into the plant and melted down (see FIG. 3).
- FIG. 6 roughly shows the composition of the amount of residual material when 1 ton of waste is incinerated.
- the concentration of the most important exhaust gas emitters was determined in addition to the regular measurements on the system in addition to the temperatures and moisture contents.
- the dust concentration in the raw gas after the boiler which in normal operation is in the middle of the usual range, increased somewhat during the test phase. This is due to an increased waste task due to poor control options.
- the clean gas meets the requirements of the TVA of the 17th BImSchV.
- the nitrogen oxide or NOx emissions during the test with filter dust additives were 2.5 times lower than in normal operation and below the regulation in Switzerland.
- the average daily value reached was approx. 141 mg / m 3 n based on 11% 0 2 .
- the sulfur oxide or SOx concentration in the clean gas rose during the experiment. This is probably due to the temperature-related decomposition of metal sulfates.
- the method according to the invention discussed here offers the possibility of melting slags, ashes and fly dusts without the supply of energy from the outside. As the eluate tests show, heavy metal compounds are practically insoluble in the slag. The molten slag also has a very low loss of ignition, and the dioxin values are not below the detection limits. In contrast to other processes, the melt does not only take place without external energy supply; it is even expected to be more efficient than conventional incinerators. The system offers the possibility of discharging waste incineration residues in an environmentally friendly manner and reducing the costs of disposal.
- the diagram in FIG. 2 shows the temperature profile measured in the test in the reactor.
- the temperature control is reduced to lower temperatures in order to lower it completely in a subsequent boiler group for the purpose of heat recuperation and recirculation.
- the solid line shows the thermal course of a theoretical (ideal) combustion and the dashed line shows the temperature course of the system in standard operation. The course shown with dots shows the melting operation.
- FIGS. 3 and 4 Two flow diagrams are shown in FIGS. 3 and 4, which, based on the process, essentially show the mass flow and the associated energy flow. It is clear that these diagrams with absolute numbers indicate a very specific course and composition, which depends on the plant and combustion material, but essentially show the effectiveness of the method according to the invention. Discussion:
- the reactor presented here essentially consists of a combination of a closed gas generation generator 2 with a mechanical feed grate 3 and a downstream rotary kiln 7 and a plurality of process-engaging connections (for example additions, recirculation etc.).
- the usual flue gas cleaners and a device for discharging the liquid slag are connected downstream. From these modules, process-engaging returns (feedbacks) lead back to the generator / rotary tube group.
- the process path begins at entry 1, into which solid and liquid waste RG, additives AD, recycled rust diarrhea RD and foreign matter FR (for example slag from other domestic waste incineration plants for melting) are introduced. These substances reach the moving grate 3, where they are smeared but not gasified with the addition of other substances such as rust air RL, vapors BR, smoldering air VL, foreign substances FR and oxygen-containing gases 02. This is achieved by blowing in a substoichiometric amount of rust air RL very slowly after being heated by the grate. Recirculated flue gas RR, vapor BR and smoldering air VL can be added through a plurality of air nozzles 4.
- the solid residues boiler ash KA and filter dusts FS as recirculation RZ or from domestic waste incineration plants as foreign matter FR can be added to the plant close to the rotary tube and melted with the residues of the generator.
- Such foreign substances and residues can also be added as dietary fiber for the targeted change in the composition of the carbonization material as soon as it is introduced.
- an immobilization of their pollutants, in particular the heavy metals is achieved.
- the A 1 '-.. "Tung on the side walls of the Genera ⁇ tors addition points 4 for feeding ⁇ > ..
- combustion air VL, vapors BR or recirculated flue gas RR In the area of transition from the grate firing capture zone to the rotary tube is a plant 6 is provided, which is used to add a preheated gas / air mixture from the area of a (provided) hood 8 above the rotary tube, and of combustion air VL, vapor BR or oxygen 02.
- afterburner 9 is after the rotary tube a further system 10 for adding combustion air VL or vapors BR is provided, as well as minimizing the heat losses, in particular in the rotary tube operated with negative pressure, which practically always has leaks, with the consequent and targeted return of unprocessed , Energy-containing substances and thermal energy, a very high process yield can be achieved.
- boiler 5 KA and filter dusts FS from the company's own plant or from external incineration plants FR can also be added via the device 5. An addition is advisable at this point so that the dust does not from the generator air guided through the grate are immediately discharged into the flue gas.
- the preheated and partially degassed solid residues of the generator get into the rotary tube.
- the air VL, 02 introduced in the area of the transition from the generator to the rotary tube causes the generator gases to burn in the rotary tube.
- the temperature reached in the rotary tube leads to a complete burnout and to the melting of the solid reaction products, which are melted away from the rotary tube.
- the melting process destroys all organic compounds at a temperature of 1300 ° C - 1400 ° C and heavy metals are permanently integrated into the glass structure of the slag.
- the glazed slag only releases little of the bound heavy metals on the surface.
- the afterburning chamber 9 behind the rotary tube there can be a supply of combustion air VL or vapors.
- the combustion air leads to the final combustion of the combustible substances of the flue gas as well as the temperature control of the flue gases.
- Thermal energy can be obtained from the boiler group 11 after the afterburning chamber by utilizing the energy content of the flue gases in the form of steam (electricity) and district heating.
- FIG. 2 now shows the approximate temperature profile of the process in the reactor.
- the process begins with task 1, where the temperature is still that of the environment. Seen in the process direction, in the generator at the beginning of the grate, the temperature is a few 100 ° C and increases with increasing swelling (gasification) at the end of the grate to about 1000 ° C, but without forming significant heat spots or hot spots.
- the temperature of the swelling is controlled by the targeted addition of rust air RL under the grate and by the addition of vapors BR and / or smoldering air VL.
- the temperature rises quickly through ignition of the carbonization gases to the high temperature range between 1200 ° C and 140Q ° C. Burning out and melting take place at this temperature.
- the temperature remains essentially the same due to the action of further supplied combustion air and then gradually drops again in the direction of the low temperature range to 1100 ° C. by the targeted addition of further (cooling) combustion air VL and / or vapors BR.
- the flue gases are cooled to 200 ° C. in the boiler 11.
- FIG. 3 shows a diagram for the addition of filter dust within the test series, which was briefly discussed above. For a little over two hours, the fractions were added in two proportions: initially about 10% based on the amount of rubbish, then about 20%. With automated addition, the task can be staggered in finer steps.
