Problems solved by technology

[0003] The prior art—the vertical pyrolysis tower used for pyrolysis of waste tires to recover industrial carbon black and fuel oil has proposed a solution for the continuous production of fuel oil and carbon black by pyrolysis of waste tires, but the detailed technical details of recycling pyrolysis oil and gas have not been disclosed; The working principle of existing technology 2 waste tire pyrolysis device is similar to the reaction kettle with external heating jacket and built-in agitator. The piece arm stirs and mixes the rubber blocks of waste tires. In order to increase the heat exchange area, the upper and lower ring discs are designed with flue gas passages to pass through high-temperature flue gas. The disadvantage is that the rubber blocks containing steel wires form viscous during the pyrolysis process. The mixture containing steel wire balls adheres to block all flow channels such as the feeding channel, thereby stopping the pyrolysis process

Embodiment Construction

[0056] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0057] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown, the process method for preparing pyrolysis carbon black from waste tires is characterized in that: Step 1, the pyrolysis of waste tires is mainly aimed at recovering pyrolysis oil and pyrolysis carbon, and further preparing products such as fuel oil and carbon black, and pyrolysis gas If it is used as the main product, it is undoubtedly uneconomical, because increasing the yield of pyrolysis gas requires a higher pyrolysis temperature of 550-600°C to break the pyrolysis oil chain hydrocarbons with larger molecular weight to generate methane and ethane with smaller molecular weight , ethylene, propylene and other components of pyrolysis gas, the higher pyr...

Abstract

The invention relates to the technical field of environmental protection, in particular to a process for preparing pyrolysis carbon black from waste tires. Its characteristics are: the particle size of the pyrolytic carbon obtained by chain roller rotary drum grinding is 41-57 μm, and if it is further ultra-finely pulverized by a circulating fluidized bed jet mill, the particle size can reach 0.5-1 μm. Medium impact crushing, the particle surface is smoother than mechanical shear crushing, the particle size is smaller, the activity is higher, and it is easier to be covered and infiltrated by the rubber compound. Therefore, the tensile strength and tear of the vulcanized rubber under the same CTAB method High strength and wear resistance.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a process for preparing pyrolysis carbon black from waste tires. Background technique [0002] Waste tires are common solid waste pollutants, and people use many ways to recycle them to achieve harmless treatment, among which the preparation of fuel oil and carbon black by pyrolysis of waste tires is one of the solutions. Chinese invention patent (patent application number is 02112328.4, patent name is vertical pyrolysis tower for recycling industrial carbon black and fuel oil by pyrolysis of waste tires) discloses a vertical pyrolysis tower for recycling industrial carbon black and fuel oil by pyrolysis of waste tires , which is characterized in that it has a closed vertical tower body, and an upper scraping and stirring device, a tire feed port and a cracking gas outlet are arranged at the upper end of the tower body, and the upper hollow heating disc and the l...
