Embodiment

[0157] use Figure 1-4 The waste tires are processed by the pyrolysis waste tire system. Among them, the waste tires are pre-treated in advance: the waste tires are pulled out of the whole steel wire by the steel wire removal device 300 (steel wire drawing machine), and then enter the crushing device 400 (crusher) for crushing, and then pass the undrawn steel wire through the magnetic separation device 500 (magnetic separator) for magnetic separation, and finally screened by particle size screening device 600 (vibrating screen sieving), and finally screened to obtain rubber particles with a particle size of less than 2mm, which are sent into the feeding hopper 700, and passed through the screw feeder 800 into the moving bed pyrolysis reactor 100.

[0158] The analysis data, process operation parameters and material balance of waste tires are shown in Table 1-Table 3.

Abstract

The invention discloses a waste tire pyrolysis system and method. The waste tire pyrolysis system comprises a moving bed pyrolysis reactor, a spray tower, heat accumulating type radiant tubes, oil gas output pipelines and dust removing devices, wherein the moving bed pyrolysis reactor comprises a pyrolysis feeding port, a pyrolysis oil gas outlet, a semi-coke outlet and a catalyst inlet. Multiple layers of heat accumulating type radiant tubes are arranged in the moving bed pyrolysis reactor in the height direction of the reactor, and each layer includes multiple heat accumulating type radiant tubes mutually parallel in horizontal direction. Through holes are formed in the walls of the oil gas output pipelines. Each dust removing device is partially embedded into the reactor and communicated with a gas collecting tube through the oil gas output pipelines and comprises a dust filtration chamber, a lifting tube and a gas collecting chamber. The system can effectively inhibit secondary splitting decomposition of oil gas and improve the oil yield of a waste tire material. In addition, the heat efficiency of the system is improved, and a system process is simplified.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular, the invention relates to a system and method for pyrolyzing waste tires. Background technique [0002] With the rapid development of my country's economy and the general improvement of people's living standards, automobiles have gradually entered people's daily lives, resulting in a large number of waste tires. In 2006, my country's tire output was as high as 280 million, ranking first in the world, and the number of waste tires produced in that year was as high as 140 million, about 3.6 million tons. The accumulation of a large number of waste tires not only occupies land, but also easily breeds mosquitoes and bacteria, spreads diseases, endangers the health of residents, and easily causes fires and environmental pollution. Recycling waste tires can not only alleviate the pressure on the environment, reduce pollution, but also realize the effective recycling of resources. [000...
