Abstract

Instead of burning rubbish completely up, which has long been the aim, the material to be processed is first merely carbonised in a low temperature unit (2) and then, with the addition of carbonising agents or gases, taken to a high temperature unit (7) to reach the temperature needed to melt the slag and achieve complete combustion. It is thus possible that foreign substances (heavy metals) are absorbed in the slag and bind permanently therein. Concerning the equipment, the original, conventional combustion region is replaced by a generator for combustible carbonising gases so that, instead of being burned, the material introduced is merely gasified. Gasification or carbonisation may be controlled in any manner. The residues from the carbonisation process contain more combustion energy than the ordinary burned residues and may be subjected to a slag liquefaction process in the high temperature unit; a rotary kiln is proposed there. The end product is a completely burned, liquefied slag which may be allowed to set in any shape.

Description

[Detailed description of the invention] Method of melting incineration residue into slag The present invention can be applied to waste materials, such as waste materials containing solid residues from domestic garbage incinerators, etc. is used as a heat source to degas, gasify, burn, and melt the waste. The present invention relates to a method and apparatus.

In addition to unburned carbon, fly ash, filter deposits, and The residual slag contains harmful heavy metal compounds and hydrocarbons.

Reduces the potential ecological hazards of slag and ensures safe storage and reuse. or in order to enable either such Legislation is underway that requires significant reductions in the amount of pollutants. Other solid residues ( There are also stricter requirements regarding smoke dust, residue after smoke pipe cleaning, and reusable residue. The distillate must be disposed of into an inert residue.

The aim of the invention is basically to minimize the unavoidable residual waste as much as possible. The goal is to reduce the amount of non-recyclable composition. very harmful residue In the case of residues, disposal of residues takes up space and is environmentally safe. Extremely expensive, especially if legal requirements for long-term safety must be met. becomes.

Conventional standard grate-type furnaces for incinerating household waste The slag is melted and permanently solidified again as heavy metals, organic compounds and sometimes poisons. Temperatures are high enough to incinerate highly toxic compounds, and such high temperatures are also possible locally. However, it was impossible to generate . This is because the slag becomes fluid. If so, will the slag get stuck between the lattices or flow out through the lattices during incineration? It is et al. In other words, currently known incineration treatment methods also also unsuitable for such processing. Assembles a grate type furnace and a rotary cylindrical furnace. Some plants use combined furnaces, but they cannot melt the slag. It is. This is because waste combustion takes place in half of the area of the furnace, and the rotary circle In the cylinder furnace, sufficient thermal energy cannot be used to melt the slag. It is et al. Additionally, these rotary cylindrical furnaces are required to incorporate molten slag. does not have developed features and equipment. The above furnace is only for complete combustion of slag used. In other cases, it is possible to increase the There are also rotary cylindrical furnaces that generate heat to incinerate waste, but they do not produce toxic slag. The problem is not considered at all.

The purpose of the present invention is to reduce environmental pollution. The problem of the present invention is to To provide a method for efficiently inactivating dust, potash and similar harmful substances. The object of the present invention is to provide an apparatus for carrying out this method. According to the present invention, waste Waste is efficiently combined and solidified, and substances that pollute the environment are converted into environmentally harmless waste ( For example, in accordance with the requirements of the waste control regulations in Switzerland, or in a recyclable form rather than waste.

According to the method of the invention, slag, dust and potash can be used as waste or thermal energy. This allows it to melt into a solid residue. Heavy metal compounds are solidified and heated Energy is maximized and organic hydrocarbon compounds are kept below current detection limits. and the volume will be significantly smaller. The basic idea of the present invention is to dispose of waste as before. Instead of burning the material completely, the waste is first carbonized in a low-temperature unit. Create a chemical situation and then use the resulting carbide or carbide gas to heat a high-temperature unit. Fluidization of the slag with complete combustion or complete incineration (e.g. in a rotary cylindrical furnace) This is done together with the government. Waste that has been carbonized has more combustion energy than and supplied for fluidizing slag in high-temperature units, e.g. rotary cylindrical furnaces be done. All or part of the energy generated by gasification is transferred to the slag in the form of gas. The process is relatively easy to control and adjust. Grilled The slag that has been fluidized through cooling treatment can finally be solidified in any desired form. .

The present invention will be explained in detail based on the accompanying drawings.

Figure 1 shows a schematic diagram of the entire plant according to the invention, in which the reactor working with waste is , a boiler and a smoke pipe section, and the basic parts of the method and apparatus according to the invention are this furnace. explained in relation to

FIG. 2 shows the temperature gradient inside the furnace measured at the test plant.

Figure 3 Adds external material in the form of recirculated filter dust to melt the slag This is a progress diagram when inputting materials, and the materials from outside are from other plants. It's okay.

Figure 4 is a diagram of the typical composition of residue in 1 ton of waste (Vehl ow literature citation).

The reactor in Figure 1 is constructed from commercially available, tried and tested components. . From a process engineering perspective, parts are assembled to achieve the desired processing. connected in series. In the reactor, processing progresses from left to right. , as the basic equipment that makes up the furnace from left to right, accepts the processing material and carbonizes the material. A feeding or dosing station having means for dosing into a grid (e.g. a feed grate) 1, and carbonize or gasify the material by chemically blowing an appropriate amount of air to generate combustion energy. A generator 2 that produces energy is arranged, and the generator 2 has a supply grade as a basic component. A child 3, a nozzle or jet 4 and a supply means 5.6 are provided. generator followed by combustion of the material and melting of the solids using generator gas. A rotary cylindrical furnace 7 is arranged, the rotary cylindrical furnace 7 being equipped with a gas/air collecting hood 8. is being given. What follows is, for example, for afterburning flammable components. It is an afterburner chamber 9 having an air supply device 10, and furthermore, the gas after combustion is Thermal energy of the smoke pipe gas is guided from the empty smoke pipe to the boiler 11. As the energy is utilized, its temperature decreases.

Furthermore, subsequently, an electrostatic precipitator 12, a smoke pipe gas cleaner for cleaning smoke pipe gas. At the end of the device 13, a chimney 14 is arranged to release the cleaned flue gas into the atmosphere. There is. Each processing step and processing route is indicated by a group of alphabetic characters in the diagram. and their meanings will be explained in turn in relation to the actuation operations.

The waste is first fed onto the feed grid of the generator via the feed means. create Under certain chemical conditions, partial degassing, gasification and incomplete combustion occur.

Therefore, it is carbonized and preheated. The most commonly used lattice system In contrast to systems, very small volumes of air are processed in generators (grids) and In addition, the air flow from below the grid to create the chemical conditions for carbonization is kept low. , the number of hot spots formed in a very small or local area is Therefore, NOw emissions are significantly reduced (roughly 50% to 70%). %) forced.

Rotary cylindrical furnace for melting solids contained in processed materials and materials from outside is connected to the generator. On the way from the generator to the rotary cylindrical furnace, Air is then injected into the furnace so that it is evenly distributed.

Materials from outside, recirculated flue dust, flue dust and slag from other plants in the same area etc. can be supplied. The carbonized gas generated by the generator burns at this location. , furthermore, the solid input is burnt. Rotation as a result of thermal energy being released The temperature in the cylindrical furnace rises above the melting point of the slag and all solids (in and outside the process material) (in the material from part) becomes fluidized. By rotating the slag in a rotary cylindrical furnace, , thoroughly mixed, homogenized, and then combusted. sura The slag is guided from a slightly inclined rotary cylindrical furnace to a precooler, and then removed from the slag. guided by the means.

Fresh air is supplied to the flue gas in the afterburner chamber to ensure complete combustion of the flue gas. The gas is completely combusted during the residence time. Instead of providing fresh air, smoke It is also possible to recirculate the pipe gas or to inject steam.

The boiler of the furnace according to the present invention is designed to withstand the high temperature flue gas in this treatment process. It must be measured. The wide radiation surface and long gas path make it possible to The high-temperature flue gas gradually lowers its temperature to below the smoke softening point. .

Next to the boiler, there is a dust filter, washer/scrubber, deNOx, and dioxy The furnace may be equipped with currently commercially available gas cleaning equipment, such as a gas separator. Traditional Go Compared to mi-incinerators, these devices can be designed with lower values of gas flow. subordinate In conventional plants, the final temperature in the combustion process is lower than in the process according to the present invention. This means that more flue gas can be generated.

In this way, the treatment according to the invention improves the efficiency of the plant compared to conventional waste incinerators. It's expensive compared to

It would be impossible to build a plant of this size as an experimental measure, as well It is also impossible to modify and construct an existing plant. However, the present invention The target is to carry out the treatment using commercially available plant or incinerator components that are recognized as advanced. It is about giving.

A plant comparable to the reactor of the present invention was specifically selected for the process tests. various The differences were considered to be within an acceptable range. The amount of waste input, i.e. the energy required for slag fluidization. It was difficult to adjust the amount of energy. The ratio of carbonization to combustion air is approximately It could only be adjusted separately. Injection injection of air for combustion and flue gas incineration is Parts were made in exact amounts and evenly distributed. Plant operational safety It was also necessary to ensure that all

Despite the above constraints, the temperature required for slag melting in the rotary cylindrical furnace during the test period was I was able to achieve the degree. When measuring the calorific value, the average H,=IO,89ok J/kg. As a result of experiments, it was found that the device of the present invention, which can adjust the air supply, A minimum amount of 7,500 kJ/kg can be treated. Lowering the melting point of slag It is also possible to add additives to promote the binding of heavy metals or to pre-heat the combustion air. This allows waste to be processed with lower calorific value. Sorting household waste and No pulverization was performed. However, it is preferable to remove the contents, e.g. metals. Delicious.

Additionally, several things must be considered. In the treatment according to the invention, the external slag from combustion plants or incinerators where melting is not possible. It is possible to simultaneously process dust, ash, etc. from rugs and other equipment.

It is also possible to supply external slag, ash, dust, etc. to the melting furnace as a thermal energy source. However, it is desirable to provide the thermal energy source necessary to maintain the process in the form of waste. .

External feeding and its melting was tested by recirculating material testing. Under examination, Slag from a domestic incinerator was introduced and melted, with positive results.

Additionally, tests were conducted to determine whether the filter dust emitted from electrostatic precipitators in the plant could be dissolved. Tested for melting. No smoke pipe residue (filter cake) residue is dumped. Ta. However, according to the invention it is also possible to process such residues in a reactor. It is. Most of the heavy metals during garbage incineration are melted and formed into permanent slag. (based on dissolution testing) to reduce waste and its volume. becomes possible. The foregoing material is combined as a slag and disposed of by melting according to the invention. can do.

The filter dust as recirculating material is removed from a special filter installed close to the rotary cylinder furnace. water-cooled lock structure (injection point 6 in Figure 1). filter dust is plant It is put inside. Approximately 10% of the amount of waste, then 20% or so of the amount of waste to the plant for a given time. It was poured and melted (see Figure 3).

During the test period, if too much waste is put in, the amount of dust upstream of the electrostatic precipitator will increase slightly. did. Although this is unlikely, even if the total increase in the dust concentration in the flue gas or the recycled material However, by analogy with the temperature, at least 91% is bound to the molten slag This means that This is approximately 82 kg to 18 kg of incinerated waste per ton. Equivalent to 2 kg of filter dust. In contrast, if 1 ton of waste is incinerated The amount of smoke inside the building is approximately 33 kg, which accounts for approximately 3%.In other words, There is a significant amount of unused garbage from other plants that has to be disposed of at great expense. The waste can be treated together with the waste by the melting process according to the present invention.

' Figure 4 shows the approximate composition of the amount of residue after incineration of 1 ton of waste.

Regarding the release of pollutants in the treatment method of the present invention, the following can be said. Elution test (CH-TVA test), some samples of molten waste slag were recirculated. If the material is injected with the material or not, filter dust should be injected for each case. Tests were conducted for both cases in which water was added and cases in which water was not added. Molten waste slurry without inputting recirculated material Not only did the material pass the TVA test for inert materials, but its combustion losses were It was 0.1% or less. Extremely common hydrocarbon compounds such as dioxins and furans All of the levels were below the detection limit. All sample test results are negative. It was shown that the TVA limits (dissolution test) for the active material were not exceeded. Re-elution In the tests (Test! and Test 2), it is difficult to exceed the TVA limits for inert materials. It was. From the test data, the slag meets legal requirements.

Tests with filter dust added to the plant's normal measurements, temperature and moisture content. In addition, the concentrations of the most important waste gas emissions were measured.

In normal operation, the dust concentration in the gas before dust collection from the boiler is within the standard range. It increased slightly during the test. This is due to inadequate controls and increased waste input. This may be due to. However, the purified gas has a T of 17B1mSch. VA requirements have been achieved.

In the filter dust injection test, the release of nitrogen oxides, i.e., NOl, exceeded that of normal operation. It is about 1/2.5, which is lower than the level regulated in Switzerland. -Nitrogen oxidation The average value of the items is 11% of 0. In this case, it was approximately 141■/rrI. Purification The concentration of sulfur oxides, i.e., SO, in the sampled gas increased during the test or This is probably due to the decomposition of sulfur metal due to high temperatures.

According to the treatment method according to the invention, an external source is used to melt slag, ash and smoke dust. There is a possibility that there will be no need to replenish energy. As shown in the dissolution test , heavy metal compounds are bound as slag and do not elute. Molten slag is also , very low ignition loss, and dioxin levels are lower than the detection limit . Not only does melting not require an external energy supply, it also eliminates the need for traditional incineration Higher plant efficiency than runts can be obtained. The plant will dispose of waste incineration residue into the environment. offers the possibility of being removed in a non-detrimental manner and at the same time with low processing costs.

Figures 3 and 4 basically show the relationship between the amount of waste and the amount of energy generated by waste. Shows a relationship. Depending on the plant, these diagrams and the final composition after treatment, demonstrating the effectiveness of the treatment method according to the present invention. There is.

These materials are induced into the supply grid 3. There, air for grid RL, steam BR1, air for carbonization VL, and material P from outside are introduced. R and oxygen-containing gas 02 are added, and combustion is not performed, but carbonization and gas be converted into This carbonization and gasification are performed by loosening the grid air RL from below the grid. Blow in rapidly and heat to create chemical conditions suitable for carbonization and gasification.

Processing methods that intentionally change the composition of input waste to facilitate carbonization It is also possible to introduce fixed material into the residue as external material. Is it external? The melting of residues and recycled materials, together with PR of other materials, can reduce contaminants, especially heavy It is possible to solidify metals. Also, combustion air VL, steam BR and recirculation smoke pipe An injection point 4 is provided on the side wall of the generator for supplying gas RR. lattice hearth A device 6 is provided near the boundary from the zone to the rotary cylindrical furnace, and a device 6 is installed to supply combustion air V.

In addition to providing processing control, these measures are particularly useful for leak-prone In a vacuum rotary cylindrical furnace, heat loss is minimized. Energy-containing materials Planned recycling of water and its thermal energy results in very high processing efficiencies. .

A device 5 located near the boundary between the generator and the rotary cylindrical furnace allows the external waste incineration plant to be In addition to the material FR1 from the factory, potash KA and filter dust FS from the external plant. It is possible to add It is appropriate to add at this point, and through the grid of the generator The passing air prevents smoke dust from quickly scattering towards the flue.

Air introduced near the boundary between the generator and the rotary cylindrical furnace■L1 acid The element-containing gas 02 causes the generator gas to burn in the furnace. Temperature inside the furnace As a result, the reacting materials are completely combusted, and the metal content is melted and exits the furnace in a molten state. be discharged. As a result of melting, all organic compounds decompose at 1.300-1400°C The heavy metals are then permanently bound into the glass structure of the slag. vitrified slag releases little bound metal from the surface.

Combustion air VL or steam BR is supplied to the afterburner chamber 9 at the rear of the rotary cylindrical furnace. It is possible to provide Combustion air is the final combustion source for the gases exiting the furnace. At the same time, the temperature of the afterburner chamber can be controlled. The boat leading to the afterburner room The thermal energy of the flue gas is recovered from the pipe in the form of steam (air) and sent to a separate location. It can be used as a heater.

Known slag and residue melting processes are often carried out externally, e.g. Requires energy supply, such as using old energy media or electricity . In the present invention, this is not necessary. In the plant according to the invention, special Due to the configuration and air circulation system, the energy content of the solid waste itself is reduced. – so that the reaction products of the generator and any additional residues are removed in the furnace. Can be melted. Compared to conventional garbage incinerators that do not melt slag, At least a lot of energy is used for other purposes (e.g. to generate electricity or to transmit heat remotely). ) is available. However, the biggest meaning is that the energy for melting is waste? This means that combustion and incineration alone produce a large amount of slag and residue. It ends up. In the treatment method according to the present invention, waste containing original solids (slag) is In addition, develop the ability to melt and process external substances.

The majority of household garbage and similar waste input into the device is highly wasteful. It is a homogeneous mixture, and the reaction results in the generator described above are uniform throughout the space. It is not something that is done uniformly. Considering the various official materials, their composition and calorific value Therefore, it is necessary to investigate in as much detail as possible which gas is generated at which point in the generator. be.

Figure 2 shows the approximate temperature gradient inside the reactor. There is even. Taking into account the processing direction, at the beginning of the grid in the generator there are several 100 ℃, and at the end of the lattice where carbonization (gasification) increases, it reaches about 1000℃. It will rise, but no significant hotspots have formed. Clearance for the grid from below the grid By adding a predetermined amount of air RL, steam BR and/or carbonizing air By adding VL it is possible to control the carbonization temperature.

At the inlet of the rotary cylindrical furnace, incineration and slag fluidization begin, but the carbonized gas is burned and The temperature then rises rapidly to the high temperature range of 1200°C and 1400°C. this temperature Incineration and melting are performed at At the point where the fuel is transferred to the afterburner chamber, the supplied fuel is The temperature is maintained at essentially the same level by the action of the combustion air, and then the cooling combustion air 1100°C by further supplying a predetermined amount of VL and/or steam BR down to the lower temperature range. In boiler 11, the flue gas is cooled to 200°C. .

Slag begins to melt at high temperatures of over 1000 degrees Celsius, and is designed for such high temperatures. Materials to be processed are transferred from the plant parts, such as grates, to the rotary cylindrical furnace, which is designed to withstand high temperatures. The figure shows that a post-melting process is carried out after removal. With the treatment method according to the present invention are intentionally treated at high temperatures in a rotary cylindrical furnace that is resistant to high temperatures; Not only does it mean that hot and high temperature processes are done in separate locations, but the thermal energy -The medium itself is also moving. In the present invention, carbonization is performed on the grid. The flammable gas generated by It reaches a high temperature in a cylindrical furnace. The means to create conditions that facilitate carbonization in the generator are: This is due to the thermal energy recovered and recycled from the rotary cylindrical furnace (hood 8). It is large.
