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

[0063] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0064] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the process system for producing pyrolysis oil and gas from waste tires is characterized by: including vertical pyrolysis tower II, feed system I, discharge system III, and pyrolysis oil gas condenser IV.

[0065] The vertical pyrolysis tower II includes a vertical pyrolysis tower body 33, a rotary rake roller 35, an upper bearing seat 32, a lower bearing seat 36, and a support foot 34, and the vertical pyrolysis tower body 33 is designed with a jacket through The high-temperature flue gas at 450-500°C is designed with hollow spiral blades inside the jacket. The high-temperature flue gas rises spirally along the channel formed by the hollow spiral blades, uniformly heating the vertical ...

Abstract

The invention relates to the technical field of environmental protection, in particular to a process system for preparing pyrolysis oil and gas from waste tires. It is characterized in that it includes a vertical pyrolysis tower, a feed system, a discharge system, and a pyrolysis oil-gas condenser; since the pyrolysis oil condensate returned by the secondary tube-sheet condenser and the cyclone separator is used as the cooling medium, it reduces The heat exchange area of ​​the condenser reduces equipment investment, and this total reflux method is beneficial to recovering the oil particles carried by the pyrolysis gas and improving the yield of pyrolysis oil.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a process system for preparing pyrolysis oil and gas 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...
