Definitions
- the invention relates to a thermal cracking process of decomposing rubber and plastic waste and to an installation for obtaining some hydrocarbons that can be industrially used.
- the horizontal drum reactors for pyroKsing are expensive, they need an investment, their automating is complicated and their maintenance is expensive and it requires high-qualified staff. It is also needed a preliminary processing of the waste and they are high-energy consumers.
- the technical problem solved by the invention consists of achieving a cracking technology and a reactor of special, simple construction, with a reduced energy use for the thermal decomposing of rubber and plastic waste for obtaining hydrocarbons that can be industrially used, without causing any ecological problems upon the environment.
- the reactor In its upper part the reactor is equipped with a worm-gear shape mixer, fixed on the cylindrical and conical wall of the reactor, powered from the lower part of the reactor anti clockwise.
- the reactor are one concentric heating shell, which contains a heating space where there are two gas burners fixed on the outer wall of the reactor and placed tangentially, two spiral pre-heaters from inside the heating space, and a pre-heater fixed to the burned gas evacuation pipe, wherein circulate the ebbing oil obtained as a result of the thermal decomposition of waste.
- On the outer wall of the reactor inside the heating space, there are also fixed some burned gas directing blades; these gases leave the reactor through an evacuation pipe situated on the upper part of the reactor.
- the waste are decomposed at a temperature between
- Part of the cracking oil is ebbed in an ebbing distribution chamber, situated in the lower part of the reactor, from where is arriving directly onto the rubber waste and the other part of it is reintroduced in the two tubular spiral heaters from inside the heating space and inside the pre- heater fixed to the gas evacuation pipe.
- the solid products carbon black and steel are evacuated in the lower part of the reactor, passing into a carbon black separator from where the carbon black of a 97% purity and a granulation between 1-10 mm is passed inside a container and directed for being used in industry.
- the invention according to the present description, has the following main advantages: - simple construction, safe in functioning, easy maintenance and no highly qualified staff is necessary - total recovery of rubber waste - reduction of the pollution factor, by the circulating of reacting products - obtaining hydrocarbons which can be used in the industry - is an economic process, with reduced consume of energy - uses its own energy obtained within the system by ebbing obtained oil, for heating and preheating both the reactor and the rubber waste that are to be terminally decomposed.
- the thermal cracking apparatus for decomposing the rubber and plastic waste for the purpose of obtaining some hydrocarbons in order to be used on an industrial scale consists of vertical cracking reactor 1; on its cylindrical wall and on its lower conical part there is fixed a worm-gear shape mixer 15 with a vertical axis 23, with a driving-gear 24,10 with a supply system 8,18 and evacuation 9,19 with the heating space 2 where there are 2 spiral tubular pre-heaters 5, where the ebbing oil flows, oil obtained as a result of thermal decomposing of rubber waste, some blades 4 for directing burned gases, two burners 3, tangentially placed on the outer wall of the reactor, with an evacuation pipe for the burning products 26 around which the ebbing pre-heater 27 is wrapped up and an ebbing distribution unit
- the waste sized between 15-200 mm are introduced into the vertical reactor 1, through a supply system 8 and 18 situated on the upper part of the reactor and in which at a temperature between 430 °C...580°C and a pressure of 50...350 mbar, wherein the waste is terminally decomposed into carbon black and hydrocarbons, gases, cracking gasoline and cracking oil.
- the gases are directed for industrial use, and the carbon black together with the solid waste are evacuated through the evacuating system 9 situated in the lower part of the reactor 1 in inside the separator 45 from where the carbon black of 97% purity and maximum 10 mm granulation is passed into a container 43 with the help of a pneumatic transporter 46.
- the liquid hydrocarbons: cracking oil and cracking gasoline are collected into pre-containers 34, 35 and 36. Because in this phase the cracking gasoline contains the condensed water, this is separated in separator 51.
- the cracking gasoline with a density between 0,7284 and 0,8200 kg/dm 3 at 15°C is stored in the cracking gasoline container 38 from where through pipe 56 it is send to be stored.
- the cracking oil with a density between 0,8200 at 0,9475 kg dm 3 at 15°C is stored in the cracking oil container 37 from where part of it is redirected in the ebbing distribution unit 39, 22 and from there a part of the cracking oil is ebbed through pipe 13 in the lower part of the reactor 1, thus getting directly on the rubber waste and another part of the cracking oil is reintroduced through coupling 14 into the two spiral tubular heaters 5 from inside the heating space 2 and inside the pre-heater 27 fixed on the gases evacuation pipe 26, and the other part is directed through pipe 55 for being stored.
- the thermal transfer space is much enlarged, the temperature needed for thermal decomposing is maintained and at the same time the hydrocarbons proportion between light and heavy fractions obtained as a cracking result can be adjusted.
