Abstract

Thermic cracking equipment, cooling device and active coal -producing equipment and technological row (4. graph), materializes the recycling of rubber, rubber waste (including wire rubber) plastics and plastic refuse and other organic materials and refuse by infrared radiance. After milling the basic material (1. graph) to the suitable size, it is added in the cracking reactor (1 graph). The heat needed for the thermic degradation is ensured by an infrared heating system (6) in which a pirolising portion unit (7) is built in. During the reaction, the process can be managed towards forming fluid or gas hydrocarbons by beforehand determinated parameters. After the fluid/gas hydrocarbons produced after the condensation are refined in the distilling towers and then it is taken in containers after slurry-decontaminating. The produced soot is cooled by a cooling device (3. draft) then it is classified and realized directly, or in activated coal-reactor it is processed to activated coal (2.graph).

Description

Equipments for processing organic materials and waste materials, principally tyre and rubber or plastic material
The object of the contrivance is equipments for processing organic materials and waste materials, principally tyre and rubber or plastic material. The object of the contrivance is specifically is a reactor for the thermic cracking of organic materials and refuse, principally tyre and rubber or plastic waste material, and producing active coal, and a cooling system for the refrigeration of false coal or soot.
Several technology is familiar for making the organic materials, rubber products and platics, harmless considering environmental protection. Most often the process is done by heating. The disadvantage of these technologies is that material recovery from the organic material does not occur, since in the most cases the matter is burnt entirely. While producing heat valuable, utility material is also burnt, on the other hand the burning process causes a high carbonic acid gas admission. Further environmentally harmful substances may arise during the burning dependent of how high the temperature is and what kind of material is burnt. By the oxides of the coal and water vapour, the product that arises during burning the waste material may contain further components, which can not be neglected as harmful material- admission, for instance in the case of plastics containing halogen and nitrogen, the halogen and nitrogen- oxide content of the flue gas may be pollutant as well. Therefore the further treatment of the flue gas might be necessary depending on the composition of the waste material which is burnt. Instead of burning the thermic tranformation of the waste material might be more economical which offers an opportunity for extracting decomposition product that may be utilized as raw material too. In these thermic crackings false coal is often produced too, which can be transformed into active coal and it is also a valuable raw material as false coal too. By changing the circumstances of the reaction further valuable raw material might be extracted beside the false coal- produce. The reaction products arising in the thermic cracking reaction are not used only for producing heat but they can be realized also as raw material. Follow from the thermic cracking the arising products are usually of higher temperature than the usual temperature of the environment, so because of the temperature difference they have utility heat energy, without burning too, which may also be used for reducing the energy demand of the process.
The application for the Hungarian patent reported with the file number P0302916 which reviews the pirolization of chopped rubber; the heat energy needed for the reaction is extracted from a furnice at a low efficiency. The flue gases and steam arisen this way are not cooled down and they are condensated in a simple device. It does not cover a solution for the utilization of the produced byproducts (false coal, steel).
The application for the Hungarian patent reported with the file number P0302916 suggests a horizontally located trommel reactor for the pirolization of rubber waste, which makes the arisen materials condensated or realizes the arisen coal after milling. The technology applies a pretty bad heat energy utilization; the warming-up is done by hot flue gas, so the energy is transmitted to the milled rubber waste through the wall of the reactor. The extracted hydrocarbons arise in a completely accidental composition, furthermore the degradating processes are managable with difficulty.
We aimed to produce a more economical complex technologic machine and reactors needed for the technologic processes, which is appropriate for the complex processing of the organic materials and waste material, principally tyre, rubber and plastic. Furthermore we aimed to develop an elaboration process that can be changed easily, by which the composition of the arisen material during the making harmless process is managable better and can be driven towards the required final products.
The aim is achieved so, that the steps of the process based on the thermic cracking and the step of the process important regarding the heat transfer is done in a separated reactor regarding the process, on the other side the reactors are shaped according to the different steps of the process. By this the cracking process might be done by more favourable conditions not only in the respect of energy utilization but the materials that arise during the chemical process may be regulated more easily in the way that results cheaper products.
The object of the contrivance is a reactor appropriate for the thermic cracking of organic materials and refuse, principally tyre and rubber or plastic material.
The object of the contrivance is furthermore a reactor producing active coal.
The object of the contrivance is furthermore the produce of a cooling system for the refrigeration of false coal or soot.
The object of the contrivance is furthermore a chemical technological device for processing organic materials and material, principally tyres and rubber or plastic material.
The reactor body according to the contrivance is equipped with a power unit, a mixer, a pulley appropriate for mixing or a transferring, a fuel oil or a fuel gas intake premixing chamber, heating unit, and a carbon-dioxide doser, a reactor gas stub, a basic material- dosing stub, and a flue gas stub, an air stub and a soot- gathering stub. Inside the reactor body a special mixing device is developed so that a centrally located, vertical pulley serves as a recirculating mixer, on which a pair of mixing element is located in a single axis. The reactor body is equipped with a horizontal pulley that runs in the lower third of it. The horizontal pulley is developed into a single unit containing a section of reverse angle with equal rotation direction .
In order to drive the mixers frequency-controlled engine is applied, hereby the reactor might be cleared out fair and the substance flow can be influenced advantageously.
For the heating of the reactor an infraradiant burner, that is in touch with the prechamber, is located. The infraradiant burner is connected with the tube reactor for a follow-up pirolization in a concrete case.
According to the contrivance the reactor that serves the development of active coal is similarly developed as the reactor that serves the thermic cracking, with the difference that it possesses nitrogen-dosing stub, the pirolizis gas stub, the soot-dosing stub, water vapour-blow stub and active coal-gathering stub.
According to the contrivance, the cooling equipment for cooling the false coal or soot is developed similarly as the reactors mentioned previously, with the difference that it is equipped with a false coal-dosing stub, a warm air stub, an air blowing stub and a coal- gathering stub. In the cooling equipment, an advantegously liquid cooling equipment is located. The heat energy of the liquid-cooling equipment driven through the heat exchanger offers an opportunity for further energy utilization. The air used for heating the reactor can be preheated or this heat might be used for preheating the basic material and the heat conservation.
In accordance with the patent, the chemical equipment for processing organic materials and waste materials, principally tyre and rubber or plastic material possesses a reactor for the thermic cracking which makes the object of the contrivance, a reactor for producing active coal, and a cooling system for the refrigeration of false coal or active coal.
A possible executed shape of the reactors in accordance with the contrivance is show on the drafts:
On the 1. draft the cross section of a cracking reactor is illustrated.
On the 2. draft the cross section of an activating reactor for activating false coal or soot arisen during the cracking process is illustrated.
On the third draft the cross-section of device for cooling false coal or soot is illustrated.
The 4. draft is the schematic illustration of a complex technologic machine. The 1. illustration shows a possible development of a reactor appropriate for the thermic cracking operating at almost athmospheric or lower pressure. The reactor body equipped with 9 reactor gas stub, 10 basic material-dosing stub, 11 fuel gas stub, 12 soot-gathering stub and closing accessories has 2 mixing elements driven with 13 power unit, 3 vertical pulley developed as a recirculating mixer, 4 horizontal pulley, 8 carbon-dioxide dosers, 26 air stub, and a heating unit. The mixers are frequency-controlled driven by 13 power unit. The heating unit is advantageously consists of a burner with 5 premixing chamber, which is connected with 6 infraradiant burner. 24 fuel gas intake and 25 fuel oil intake is connected to the 5 premixing chamber. In the 5 premixing chamber a perfectly burning mix is developed from the gaseous and liquid fuel through the intake connected to it, it covers the heat necessary for the reaction. The burning products of the fuel, that is able to be burnt perfectly, driven out through the 11 burning product stub and driven through the spaces for the preheating and heat conservation of the basic materials, can be bounded straight to the chimney. The 6 infraradiant burner enable an efficient heat-transmission on the one part, while it also hinders advantageously the flame of the heating from assorting directly with the decomposition products of the thermic cracking of the waste material and being burnt. The 6 infraradiant burner made of silicon-carbon is advantageously appropriate as heating unit, which enables an energy saving heat transmission, while it terminates the burning reaction and the heat- cracking reaction from each other. In the 1 reactor body 4 horizontal pulley is developed in the lower third of it, which have two sections of reverse angle with equal rotation direction. The two sections of reverse angle with equal rotation direction is shaped into a single unit. This is advantegous because of the mixing and the conveying.
One pair of the mixing elements of the cracking reactor is equipped advantageously close to the inner wall of the 1 reactor body, while the two mixing elements of the other pair is equipped close to the 3 vertical pulley, which is enables an advantageous flow inside the reactor body.
The 6 infraradiant burner is bounded to the 7 pirolizing tube reactor used for follow-up pirolizing. This development of the heating unit enables advantageously the execution of paralell thermic cracking processes, mainly pirolises.
The gaseous components of the thermic cracking leave the reaction space through the 9 reactor gas stub. The 9 reactor gas stub is bounded to usual technologic devices for the cleaning, the separation and further process of the decomposition products. The 7 pirolizing tube reactor is bounded close to the heating element. The components of the decomposition products leaving the cracking reactor that need further cracking can be cracked further with little loss of heat. The accessories of the cracking reactor that assort with the basic material directly, are made of austinated steel of high nickel content. When the 4 horizontal pulley driven by 13 frequency- controlled power unit is applied, not only the conveying time can be reduced but the opportunity that basic material mostly of rubber content with non-newtonic viscosity would snatch up. With this development the basic material is stirred better than earlier inside the whole volume of the reactor.
On the 2. draft advantagous development of the reactor serving the activation of false coal or soot is illustrated. The 2. draft reviews a false coal-activating reactor for the further process of false coal produced in the cracking reactor. On the 2. draft the advantagous development of the reactor serving the activation of false coal or soot is illustrated. The 2. draft reviews a false coal-activating reactor serving the further process of false coal produced in the cracking reactor, which is a false coal-activating reactor developed with a 1 reactor body operating at atmospheric or at a more advantageously lower pressure than the atmospheric pressure. The reactor illustrated on the 2. draft is developed very similarly to the cracking reactor illustrated on the 1. draft. The false coal-activating reactor has a heating reactor similarly developed as the cracking reactor illustarted on the 1. draft and the heating unit of the activating reactor illustrated on the 1. draft bounded to the 7 pirolizing tube reactor is used for this purpose advantageously. The false coal-activating reactor has 2 mixing element equally developed to the cracking reactor, its 3 vertical pulley furthermore 4 horizontal pulley developed to centrally located, recirculating mixer. As it can be seen clearly on the draft the reactor that serves the activation of the false coalhas 14 nitrogen-dosing stub, 15 pirolisis gas stub, 16 soot-dosing stub, 17 water vapour -blowing stub, 26 air stub and 23 active coal-gathering stub.
The 6 infraradiant burner with the 5 premixing chamber can be applied economically. Beside the fuel gas and fuel oil other substances that are inappropriate for further processing and may arise from pirolisis either and crack gas or crack oil can also be burnt. The burning product not demanding further making harmless might be driven through 11 flue gas stub and technologic establishments serving preheating or heat conservation and can be bounded straight to the chimney.
The 7 pirolizing tube reactor is made of not austenited steel alloy with an advantageously high nickel-content.
On the 3. draft an advantageous combinated liquid and air refrigerant cooling machine for cooling false coal assortments is illustrated. The reactor developed to perform a thermal operation, illustrated on the 3. draft, is also appropriate for cooling the coal arisen in the cracking reactor and the false coal-activating reactor. The mechanic development of the rector is similarto the development of the cracking recator, illustrated on the 1. draft and the false coal-activating rector, illustrated on the 2. draft with the difference that instead of the heating unit accessories serving the cooling are built in the reactor. The cooling equipment operates at atmospheric pressure or at higher pressure than the atmospheric. In the cooling equipment 2 mixing element inside 1 reactor body and 3 vertical pulley, and 4 horizontal pulley, that is developed into a centrally located, recirculating mixer, are built in. The cooling equipment possesses 22 false coal-dosing stub, 19 air-blowing stub, 18 warm air stub, 20 soot-gathering stub and a 21 spiral-executed liquid heat exchangers. The 21 liquid refrigerator is configured so that the equipment is able to preheat the air advantageously at the same time. The elements of the cooling equipment serving the mixing, that are configured equal to the mixing elements of the cracking and the false coal-activating reactor, are operated by 13 frequency-controlled power unit.
21 liquid heat-exchanger may be configured fitting the complex technologic equipment if it is developed as a liquid heat spiral inside 1 reactor body that it contains a space appropriate for preheating the air.
If the 4 horizontal pulley is operated by the 13 power unit, then the operation time of the cooling may be advantageously reduced as well and conveying out the final product can be simplified.
The 4. draft is the outline of a complex technologic flowchart, which reviews the schemic execution of a complex technologic equipment, that can be developed by a possible connection of the cracking reactor according to the 1. draft and the false coal-activating reactor according to the 2. draft and the cooling equipment according to the 3. draft. Although the equipments of the supplementary operation ranges are illustrated only schematically, the substential characteristic of the draft is that no technologic equipment for operating any catalyzer or material flow are illustrated. Since an important advantage of the complex technology is that there are no processing steps of the catalyzer, and no material flow for operating and regenerating the separating catalyzer because of the appropriate selection of the structure material.
The schematic flowchart (4. draft) of the complex technology reviews only the connection of the cracking reactor, the false coal-activating and the suggested cooling equipment, representing the usually applied technologic equipments and connecting points. In the left of the 4. draft the cracking reactor is bounded to the 27 basic material-dosing machine through 10 basic material stub. The 20 soot-gathering stub of the cooling equipment is joins the 22 false coal-dosing stub of the cooling equipment. The 20 soot-gathering stub of the cooling equipment is bounded to the 28 final product processing row. The 27 basic material -dosing receiver and the cracking reactor join the 29 chimney through the 11 flue gas stub. The 18 warm air stub of the cooling equipment is connected to the 26 air stub of the cracking reactor.
In the case of the previous connecting method the solid final product is coal. The false coal may be transformed to activated coal as well. In this case the connecting method in the right side of the 4. draft comes into operation.
The 16 soot-dosing stub of the false coal-activating reactor diverges from the 28 processing row and its 11 flue gas stub is bounded to the 29 chimney. In order to cool the solid-phase products, the 23 active soot-gathering stub is connected to the 22 false coal -dosing stub of the cooling equipment. The 18 warm air stub of the cooling equipment is connected to the 26 air stub of the false coal-activating reactor, while its 20 soot-gathering stub is in touch with the 28 final product row.
In the case of the connecting method repesented in the left side of the draft the complex technologic process is the following:
The oxigen content is reduced in the cracking reactor by dosing carbon-dioxide through 8 carbon-dioxide-doser before filling. The cracking reactor can be filled with dimensioned preheated basic material through 27 basic material equipment. The heating unit reviewed on the 1. and 2. draft serves the heating or if required the preheating of the cracking reactor. For preheating the cracking reactor or if necessary the false coal-activating reactor the heat of the side by side operating reactor can also be applied. This heat may also derive from the cooling equipment according to the 3. draft. We can produce a combination which can be burnt completely from the fuel which is usual in the 5 premixing chamber. For producing the necessary energy for the cracking, the cracking oil and cracking gas sorts of components in the 5 premixing chamber. The oil or the gas is portioned in the 5 premixing chamber through the 25 fuel oil or 24 fuel gas intake.
After finishing the filling, the temperature is raised and the charge of the reactor is cracked by operating the heating elements, advantageously applying three heating units. The heat energy leaving through the 11 flue gas stub can be utilized advantageously for preheating the basic material and conservating it at 15O0C .This is an advantageous temperature because the possibilty of self-ignition may be eliminated and the demand for the thermic cracking can be reduced as well by fractional incorporation. The cracking is done at 200 - 1200 °C, advantageously at 350 - 600 °C by operating the 3 vertical pulley and the 4 horizontal pulley and the 2 mixing elements continuously. The cracking is executed at almost atmospheric pressure or reduced atmospheric pressure. Different polimers can be cracked advantageously in the range of 0,2 — 2 bar pressure.
The adherence of the basic material inside the reactor must be specially observed during the cracking. The adherence of the basic material is specially harmful if the mixture of inhomogeneous substantial composition, for instance wired chopped tyre surrounded by rubber is cracked. The basic material that adherences on the structural elements of the reactor for a long time is disadvantageous in the respect of the composition of the reactor gas arisen in the thermic cracking.
By the appropriate operation of the frequency-controlled engines of the 13 power unit efective flow can be maintained inside the reactor volume. By applying the 13 power unit with frequency-controlled engines the felt-like clotting of the steel-wire can be reduced advantageously and smaller aggregates evolving in a felt-like way can be cracked. This is an advantageous development beacuse the operation in the reactor must not be stopped in case of wire aggregates evolve. The development of metallic felt-like formations can be perceived from far outside the reactor body.
The 26 air stub of the cracking reactor is kept in a closed position during normal operation and the composition of gas in the reactor is observed continuously. By emergency shotdown the 26 air stub might also be applied for vaccine overflow
The fraction of the long coal range (mainly of liquid base) of the compound leaving through the 9 reactor gas stub can be processed directly or they can be pirolized advantageously into substances of shorter coal range in a 7 pirolizing tube reactor connected to the 6 infraradiant burner. The cracking oils and other fractioned products produced in the thermic cracking reaction, which relatively arise in a small quantity, may be processed fractionally in the 7 pirolizing tube reactor, which is connected to the 6 infraradiant burner. When a 7 pirolizing tube reactor connected to a 6 infraradiant burner is built inside the reactor, then several pirolizing processes can be executed at the same place.
Finishing the cracking the 9 reactor gas stub is closed. The solid phase remains of the cracking can be removed out of the reactor through the 12 soot-gathering stub so, that the rotation direction of the 13 power unit is changed. For these functions the power unit with frequency-controlled engines can be applied advantageously, since the direction of the rotation can be changed simply by the 13 power unit.
After conveying out, the thermic cracking of further portion of basic material can be executed. During conveying out the false coal gets into the cooling equipment, where it is cooled to 250 -350 0C, advantageously to under 300 0C.
The false coal, dependent of the kind of the basic material, is driven through the separator of the 28 final product-processing row and the metallic remains, which are realizable separately, can be extracted out of it. The cooling of the false coal takes place in the cooling equipment. If the products that are rich in hydrocarbons, leaving through the 9 reactor gas stub, are processed by further operations, can be realized as chemical basic materials or source of energy. The soot-like false coal can be realized as substantive final products. The connecting method which is illustrated on the 4. draft serves the production of active coal.
The false coal that is soot-like regarding its composition, arisen in the cracking reactor, is filled from the soot receiver of the 28 final product-processing row through the 16 soot-dosing stub in the false coal activating reactor. Before take in and under this period the oxygen- discharge in the false coal activating reactor is superintended. Under the period of the portioning and in the period of the heat conservation of the activation, the activation id done with nitrogen, after the period of heat conservation the activation is done with different steam/nitrogen compounds, advantageously with 75/25 proportioned compound. From the take in to the gathering of the final product, the material filled in the reactor is stirred by the 2 mixing elements and the 3 vertical pulley and the 4 horizontal pulley. After finishing the take in, the false coal-activating reactor is heated to 600 - 1000 °C, advantageously to 800 - 850 0C by burning the fuel mixture mixed in the 5 mixing chamber and burnt in the 6 infraradiant burner. Meanwhile the pressure of the reactor is kept at a rate that is smaller than the atmospheric pressure, advantageously at 0,1 — 0,5 bar. In order to produce active coal of a deliberately good quality the specially advantageous balance pressure should be maintained, which is important in the sight of the quality of the material being produced in the activating step. During activating in the preheating period in the reactor, for the heat maintenance at 850°C, 60-600 minutes, advantageously almost 2-3 hours long, 10 - 1000 dπrVmin, advantageously almost 100 dmVmin nitrogen power is maintained. The flue gas components leaving through the 15 pirolisis gas stub can be utilized as fuel or by further occurrent operations after the condensating. After the heat-maintaining period, the nitrogen-atmosphere is changed with a disadvantageous 75/25 proportioned steam/nitrogen compound, the flow speed of which is equal to the flow speed of the nitrogen gas. This time the flow speed of the nitrogen gas is reduced advantageously to 80 dm3/min, and steam is developed so that 300 - 800 cm3 ,advantageously almost 450 cm3 water is portioned in the equipment by a peristaltic pump. This quantity of water equals with almost 600 000 cm3/min steam at 20 °C and 1 atm pressure. The water vapour dosing is maintained at almost 850 °C for a further period, advantageously almost 2 hours. Then the temperature is raised to 900 - 1200 0C5 advantageously to 925 - 950 °C. After finishing the activation the nitrogen and the water portioning the 15 pirolisis gas stub is closed, and the active coal is conveyed out by the 4 horizontal pulley through the 23 active coal-gathering stub into the cooling equipment. The cooling is done at 250 -350 °C, advantageously under 300 °C, beside excluding oxygen. After the cooling the active coal is processed on the 28 final product-processing row. The heating unit of the cracking and false coal activating reactor and the liquid and air- cooling ranges can be connected to further technologic equipments, and hereby the energy demand of the complex technology can be reduced.
In the case of a solution when a 7 pirolisis tube reactor, that is bounded to the 6 infraradiant burner, is built within the 1 reactor body of the cracking and the false coal activating reactors, then several pirolizing processes can be executed at the same time, which might have different basic materials either. Therefore different crack-oils and crack-gases can be processed side by side.
By the reactors and the technologic equipments according to the contrivance polimers chopped to 1-10 cm and organic substances and waste materials, advantageously to 2-8 cm chopped rubber, 2-6 cm chopped tyre, 2-8 cm chopped different plastics, for instance different polyethylenes, polyprophyles, polystyrenes, polyamids and other plastcis, or the mixtures of them that are unclassed regarding the material quality. By the accomplishment according to the contrivance chemical basic materials and fuel or firings can be extracted out of waste materials, the energy demand of the accomplishment might be reduced by utilizing the waste heat. The complex technology may be appropriate for the thermic cracking of different basic materials by proportional guidance.
The premixing chamber-infraradiant burner development is not only favourable energetically , but its further advantage is that the investment demand and its maintanance of the thermic cracking is more favourable as well. In the flue gas range it is not necessary to establish and operate a technologic investment, that is usual for the treatment and making harmless of the further flue gas components, arising beside the carbon-dioxides.
The accomplishment of the mixing according to the contrivance enables the stoppage of the mixing in a concrete case or the felt-like formations that may cause fraction in an extreme case may be cracked so the reaction can be continued its stoppage.
Therefore this development of the mixing is more favourable and in the respect of energy and the capacity of the thermic cracking than the accomplishments known before.
