According to the technical scheme, the device comprises a preprocessing unit, a conveying and feeding unit, a thermal cracking unit, a desulfuration and atomization unit, an oil gas purifying and condensing unit, a carbon black deep processing unit, an oxygen supply air blower and a fuel gas spray gun, wherein the preprocessing unit, the conveying and feeding unit and the thermal cracking unit are connected in sequence, the desulfuration and atomization unit, the oil gas purifying and condensing unit, the carbon black deep processing unit, the oxygen supply air blower and the fuel gas spray gun are connected with the thermal cracking unit, a tail end outlet of the preprocessing unit is connected with the conveying and feeding unit, the thermal cracking unit mainly comprises a furnace body, the furnace body is connected with the oxygen supply air blower and the fuel gas spray gun, and the fuel gas spray gun comprises a natural gas spray gun and a waste gas spray gun. The waste tire low-temperature and normal-pressure continuous thermal cracking production device has the advantages that a full-sealed structure is adopted in the production process, and a strong atomization tower is adopted for performing cooling, dust removal and purification, so that environment pollution is lowered to the minimum; due to the fact that recycled combustible gas and cooling water is recycled, purified and secondarily utilized, energy is saved, the production cost is lowered, and the principle of energy conservation and emission reduction is met.

Description

technical field [0001] The invention relates to the technical field of a low-temperature and normal-pressure thermal cracking device and a production process, in particular to a low-temperature and normal-pressure continuous thermal cracking production device and process for waste tires. Background technique [0002] As a renewable resource, waste tires are called "black gold mines". The recycling of waste tires is a "sunrise industry" that develops circular economy and takes the road of sustainable development, and has a very broad prospect. my country is the largest consumer of rubber in the world, with an annual production of more than 400 million tires. According to statistics released by the China Association of Automobile Manufacturers, the production and sales of automobiles in my country both exceeded 18 million in 2010, a year-on-year increase of 32.4% and 31.3% respectively. Ranked first in the world and set a new record in global history. Although affected by th...

Problems solved by technology

At present, in the thermal cracking production line adopted in the waste tire recycling industry, the thermal cracking device is complicated, there are many supporting equipment, and there are many signal parameters for monitoring and control. The current process is to crack the steel wire in a single furnace, that is, one furnace cracking After the completion, after the material is discharged, the cracking of the next furnace can not be realized, the work efficiency is low, and the material needs to be continuously fed in and out, and it is mainly through manual monitoring and operation. Inaccurate, easy to pollute, labor-intensive and difficult to handle pyrolysis products, etc., resulting in a lot of manpower and material consumption and environmental pollution, resulting in high costs, and product quality cannot be effectively improved
