Description

 Industrial continuous waste tire cracking device

 The present invention relates to an industrial continuous waste tire cracking apparatus for converting waste tires into high quality clean liquid fuel and carbon black. Background technique:

 With the rapid development of the automotive industry, the production of used tires is also increasing. According to the World Health Organization, the world's waste tires have reached 3 billion, and they have grown by an astonishing number of about 1 billion a year. The environmental hazards caused by a large number of used tires have caused people's worries, and government departments in various countries and regions are striving to find the most ideal treatment.

 The use of cracking of used tires to produce clean oils and carbon black is currently the most effective treatment. However, in developed countries such as Europe, the United States, and Japan, due to the complexity of the design scheme, the huge size of the equipment, the huge amount of investment, and the unqualified carbon black products, they cannot become commodities and have no economic benefits. Therefore, with regard to waste tire cracking technology, large-scale industrial production is less likely to occur in these countries and regions, and even stagnate. Summary of the invention:

 In view of the above deficiencies of the prior art, it is an object of the present invention to provide an industrial waste tire continuous cracking apparatus.

 (The following description is also an embodiment of the actual implementation, and the detailed description may refer to the accompanying drawings, which illustrate a technical solution provided by the present invention, in which the connections of the devices are all part of the present invention).

 It consists of a horizontal reaction system with a closed and inclined position (high feed end and low discharge end) and heating system. The reaction system is divided into a rotating inner cylinder 10 and a stationary outer cylinder 9 . The rotation of the inner cylinder 10 is achieved by a refining mechanism 12 provided at one end, the support being realized by a rolling mechanism 5 provided at each end. The inner and outer cylinders are heated chambers with a super-thermally conductive carrier 7, and the outermost layer is a moisturizing layer 8 . There is a feeding box at one end

Confirmation 1. Catalyst inlet 1 An automatic feeder 3 driven by a motor, a thermocouple 4 and a superconducting dry body inlet 6. The other end is provided with an ultra-heat-conducting carrier outlet 11, a refining transmission mechanism 12, a cracking oil and gas outlet 13 and a discharge opening 14 to form an automatic discharge system. In addition, a rolling mechanism 5 for supporting the inner cylinder is provided at each end. The heating system consists of a heating furnace 17, a temperature gauge 18, a high temperature transfer pump 19, a reflux tank 20, a heat carrier transfer line 21, and a superconducting heat carrier 7.

 The cracking device can be described as a cracking device with excellent performance. Its main features are:

 (1) The heating method is unique. Due to the unique super-thermally conductive carrier heating method in the industry, it can simultaneously achieve "liquid phase dynamic heating" (ie liquid (super-thermally conductive carrier) circulating heating) and "material (waste tire) dynamic heating" . Therefore, the cracking performance, conversion rate, temperature control and regulation, oil yield, thermal efficiency, oil and carbon black quality, operational safety and equipment life, as well as economic benefits, are all in an ideal state. status.

 (2) The method of cracking is unique. Due to the "liquid phase dynamic heating" and "material (waste tire) dynamic heating" low temperature catalytic cracking process, complete catalytic cracking can be achieved without too high heating temperatures.

 (3) Fast and precise adjustment and control of temperature, low energy consumption;

 (4) The conversion rate is high, and the conversion rate measured after implementation is 98% or more;

 (5) The quality of oil and carbon black is good. Since the above heating method determines the low temperature cracking process, at a relatively low temperature, heat can be quickly and evenly distributed to all parts of the lysate to achieve complete catalytic cracking. Therefore, the oil yield is high, the gaseous product yield is low, the carbon black is not internal combustion, the ash content is small, the standard can be achieved, and the quality is good. Therefore, oil products, carbon black and other products can all be turned into commodities with significant economic benefits.

 (6) The operation is carried out in a fully enclosed state, no impurities are entered, no cracking gas, liquid oil and dust leakage, and product quality and safety are guaranteed.

(7) The device is well designed, rigorous and reasonable in structure, stable in operation, safe, reliable and efficient, and will not cause secondary environmental pollution. It can fully meet the strict requirements of safety and environmental protection in developed countries. The whole device processing program is simple, the operation is fully automated, and the operation can be reduced. Labor costs. BRIEF DESCRIPTION OF THE DRAWINGS:

 The industrial continuous waste tire disintegration device according to the present invention is composed of a horizontal reaction system and a heating system which are placed in a closed and inclined state. The reaction system is divided into two parts: a rotating inner cylinder 10 and a stationary outer cylinder. The rotation of the inner cylinder 10 is achieved by a refining mechanism 12 provided at one end of the discharge opening 14, the support being achieved by a rolling mechanism 5 disposed near the ends. At one end there is a hopper 1, a catalyst inlet 2, an auto-feeder 3 driven by a motor, a thermocouple 4 and a superconducting heat carrier inlet 6. The other end is provided with a superconducting heat exchanger outlet 11, a transmission mechanism 12, a cracking oil and gas outlet 13 and a discharge port 14. Further, a rolling mechanism 5 for supporting the inner cylinder is provided adjacent to both ends of the reaction system. A superconducting heat carrier 7 is passed between the inner and outer cylinders to provide the required heat for the cracking reaction system. All exposed parts of the reaction system are covered with insulation layer 8, to prevent heat loss. The bracket 16 and its upper surface and the support 15 are used to support and secure the reaction system. The heating system is composed of a heating furnace 17, a temperature gauge 18, a high temperature pump 19, a reflux tank 20, a conveying pipe 21, and a superconducting heat carrier 7.

 The crushed scrap tire pieces and the appropriate amount of catalyst are respectively fed into the feed tank 1 and the catalyst inlet 2, and then fed into the continuously rotating inner cylinder 10 of the reaction system by the automatic feeder 3. During the movement of the material in the cylinder from the left to the right due to the action of gravity, while fully mixing with the catalyst, the heat is continuously absorbed to carry out the cracking reaction. The oil and gas of the cracked product is continuously discharged from the oil and gas outlet 1 3 and is cooled by an external condensing cooler to become a fuel oil. After further sub-laying and blending, the gasoline and diesel fractions can be obtained. After the cracking of the scrap tire is completely completed, the remaining crude carbon black is discharged from the discharge port 14 and processed by the carbon black reduction treatment system to process the synthetic carbon black.

 The heat required for the cracking reaction is provided by the heating system. The heat is carried by the heat carrier from the inlet 6 into the heating chamber between the inner and outer cylinders of the reaction system, and further transferred to the lysate in the inner cylinder to be fully cracked. Moreover, the temperature regulation and control is fast, accurate and uniform.

 The entire unit is operated in a fully enclosed, fully automatic, unmanned state.

 After implementing the equipment of the present invention, we have found that the waste car tire cracking device developed by our generation is horizontal, direct heating, high temperature cracking, poor safety performance equipment is easy to damage, contaminated equipment after about three months of operation, subject to Living at high temperatures has been destroyed.

Our second generation uses vertical indirect heating and low temperature cracking. It is batch production. This kind of equipment is safer than the next generation. Because it is indirect heating, it is not easy to damage the equipment, and the effect is good, but the batch Production, causing secondary pollution, is not ideal.

 Nowadays, the fully-sealed automatic continuous cracking device has been developed. It adopts more than 480 °C heating method to heat cracking, and it is stable at low temperature. It is stable, safe and reliable, saves time and effort, and is highly efficient. It completely solves the problem of secondary pollution.
