Waste tire thermal decomposition system

Abstract

The invention relates to a waste tire thermal decomposition system which comprises a feeding device, a reactor and a discharging device, the discharging device and the feeding device are arranged at the two ends of the reactor, the discharging device comprises an oil gas discharging unit and a solid discharging unit, a chain playing a transmission role is arranged in the reactor, and the waste tire thermal decomposition system further comprises a coke removing device. The coke removing device comprises a pipeline communicating with the reactor, a chain synchronously moving with a chain of the reactor is arranged in the pipeline, a transmission wheel is arranged at the end of the pipeline and is synchronous with a driving wheel of the chain, the chain comprises a chain link, the chain link comprises a butterfly-shaped scraper, and a connecting shaft extending out from the middle of the butterfly-shaped scraper to two sides is arranged perpendicular to the middle of the butterfly-shaped scraper. The connecting shaft and the butterfly-shaped scraper are integrally formed. Coke in the pipeline can be scraped at any time, condensate oil in the pipeline is reasonably utilized to clean and lubricate the coke removing device, self-cleaning and self-lubricating are achieved, the design is very ingenious, and the coke removing device can be widely applied to a waste tire thermal decomposition system.

Description

technical field [0001] The invention relates to a waste tire thermal decomposition system. Background technique [0002] The thermal decomposition system of waste tires in the prior art generally crushes waste tires, then proceeds to decompose them in a reactor, and then takes out the decomposed pyrolysis oil, combustible gas, carbon black, iron wire, etc., and then carries out reprocessing. Utilization, because the oil will decompose and vaporize when heated in the reactor, so in the whole reaction process, there are both oil vapor and oil in the reactor in many cases, so it is necessary to separate the oil vapor and oil, but due to its own characteristics, often Coking will occur during the reaction. There are many methods for coking removal in the prior art, but none of them is economical. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a waste tire pyrolysis system that can not only run...
