Description

Device for separation of pyrolytic oil during scrap rubber processing
Field of the invention
The solution relates to the device for heat treatment of scrap rubber, which construction is solved so that it optimizes the possibility to separate utilizable pyrolytic oil from flue gas during pyrolysis of rubber.
Present state of the art
Current devices for heat treatment of scrap rubber are arranged for pyrolysis of rubber by direct heating of the pyrolysis chamber cavity with a flame of burners. The pyrolysis chamber has principally a shape of furnace, which walls and possibly bottom are equipped with heat sources for heating. These are flame burners with a flame blazing directly into the pyrolysis chamber cavity, or it is electric heat source situated in the pyrolysis chamber cavity or it is a combination of both ones. Waste tyres or other rubber based wastes are also placed into the pyrolysis chamber cavity, and these wastes can be deployed in suitable stand because of better heat access. Device according to CZ U 12571 has for example such configuration. This device attains pyrolysis of rubber, however handling with gases released by pyrolysis is not solved. Pyrolysis of rubber releases not only common smoke exhaust, but also petroleum substances and other substances that must not be discharged to air because of environmental reasons. Nevertheless, combustion gases from rubber pyrolysis contain utilizable components that can be secondary products utilizable further in the industry or for other purposes. Device according to CZ U 12571 is equipped with only one simple smoke flue for outlet of combustion gasses where disposal of exhausts in the outgoing smoke by combustion in direct flame is taken into account. This is achieved by placing gas burner across and above the smoke flue. As a result of the said device configuration, the exhausts from pyrolysis are mixed in the pyrolysis chamber with smoke from the burners used as a heat source. Depending on the concentration of pyrolysis exhausts, which can irregularly fluctuate during the pyrolysis process, ignition of pyrolysis exhausts and thus clarification of combustion gases can occur. Because the ignition of exhausts depends on their concentration, there is a risk of leakage of unwanted exhausts into a smoke flue and possibility of sudden ignition here, but also possibility of sudden ignition and burning of pyrolysis exhausts in the pyrolysis chamber accompanied by expansion. Thus this solution constitutes risk of unwanted explosion and it does not allow for targeted utilisation of pyrolysis exhausts even after their secondary processing.
Technically more advanced solution is represented by the device according to CZ U 12817. The device has lockable heating chamber in which heat sources, smoke flue, and revolving drum are located. Pyrolysis chamber is basically created by revolving drum into which cavity the scrap rubber is inserted. The revolving drum is created as a horizontally situated cylinder on a shaft. The shaft is hollow, equipped with openings for input of pyrolytic gasses, and it is extended into an exhaust duct for outlet of pyrolytic gasses into the next combustion chamber, where the contained exhausts are disposed of by combustion. The combustion chamber has its own smoke flue, which can be disembogued into smoke flue from the heating chamber. This device has already space for pyrolysis of rubber separated from the space with heating elements and outlet of usual combustion smoke products from burners separated from the outlet of pyrolytic gasses. This eliminates the risk of explosion in the space where pyrolysis takes place. However even this device does not allow collection and processing of utilizable substances from pyrolytic gasses, but it counts on their complete or predominant disposal in the combustion chamber. Other disadvantage of this device is that the direct contact of pyrolytic gasses with the flame in the combustion chamber constitutes risk of unwanted explosion and possible back-flash into the input duct of these gasses from the z pyrolysis chamber, and therefore it is necessary to continuously monitor and adjust the temperature and concentration of pyrolytic gasses, which requires additional costs and constitutes demands on handling during operation. In the case when cooling of pyrolytic gasses occurs, condensation of pyrolytic oil takes place, which in this configuration represents only unwanted fouling of ducts without the possibility of collecting and further utilisation.
Essence of the invention
The disadvantages of the present state are eliminated by the invention. Device for separation of pyrolytic oil during processing of scrap rubber is invented, which includes a pyrolysis chamber outwards of which a heating space formed as at least one heating chamber is located, where the pyrolysis chamber is openable and has a pyrolysis cavity inside for placing scrap rubber and its pyrolysis. The heating chamber has a heating cavity inside, in which heating elements are situated. The pyrolysis chamber is equipped with at least one outlet for outlet of pyrolytic gasses connected to an exhaust duct separately from the space of the heating cavity. The essence of the invention is that the exhaust duct is disembogued back to the pyrolysis chamber, into its pyrolysis cavity, while the exhaust duct contains at least one cooling section between its outlet and a mouth, where at least one collecting tank is connected for collection of pyrolytic oil.
Device for separation of pyrolytic oil during processing of scrap rubber according to the invention has preferably the exhaust duct equipped with at least one driving device, rather suction device, to ensure flowing of contained medium.
If suction device is used to ensure flowing of medium in the exhaust duct, it is preferably situated in the vicinity of the mouth of the exhaust duct into pyrolysis chamber.
The heating cavity is preferably equipped with at least one electric heating element. The main advantage of electric heating elements is their flameless operation ensuring operation safety and does not require solution of additional oxygen input and output of vapours. However, alternatively or simultaneously, the heating cavity can be equipped with at least one burner. In such case the heating chamber is equipped with at least one smoke flue for outlet of combustion products from the heating cavity. Oxygen for combustion can be ensured by use of suitable burners equipped with oxygen inlet.
The pyrolysis chamber is preferably equipped with at least one safety element for prevention of exceeding the maximum allowed temperature in the pyrolysis chamber.
The said safety element is preferably represented by at least one sensor and a nozzle with inlet of cooling medium, which could be located on a common body.
The said safety element in its optimal embodiment carries at least one sensor for temperature check and optionally at least one sensor for checking of pressure and/or pyrolytic gas concentration.
Cooling section of the exhaust duct has preferably at least one part created with downwards slope where the collecting tank is connected in the lowermost point. Said cooling section has also preferably an array of arches consisting of at least two arches with peaks underneath where the collecting tank is connected to these lower arches. One collecting tank can be in each peak or one common collecting tank can be connected.
The invention allows processing of scrap rubber by effective and environment friendly way. The device is relatively undemanding regarding costs, space requirements, handling as well as requirements on the operating personnel qualification. It can have a form of a mobile unit or it can be assembled from components in the field as a modular device. Therefore it is also suitable for temporary operation on various locations according to the needs, such as directly near the landfill, scrap-yard, tire service etc. The device allows safe processing of an environmentally problematic rubber based waste such as tires, rubber bands, rubber seals etc. without the risk of explosion, and that without leakage of harmful combustion products into the environment. By operation of this device, disposal of rubber based waste is accomplished with formation of utilizable raw materials and products. For example in the case of tyres, recovery of raw materials in the form of separated carbonaceous chippings from tyre rubber, steel cords released from tyres, and pyrolytic oil from gasses released by pyrolysis is achieved.
