Waste and old tire colloidal particle cracking system and method

Abstract

The invention discloses a waste and old tire colloidal particle cracking system and method. The system comprises a conveying device, a breaking device, a washing device, a drying device and a cracking furnace are sequentially connected to the conveying device, the cracking furnace is further connected with a molten salt furnace, the molten salt furnace is connected with the drying device through a transition salt pipe, the drying device is connected with the molten salt furnace through a salt returning pipe, the cracking furnace is further connected with a gas and slag separation device, the gas and slag separation device is connected with a carbon black tank and a steel wire recycling device through a magnetic separator, and the gas and slag separation device is further connected with a rectifying tower; a gas pipe is further communicated with the cracking furnace, the cracking furnace and the gas and slag separation device are arranged side by side, the conveying device penetrates the cracking furnace to stretch into the gas and slag separation device, a slag cavity is formed in the lower portion of the gas and slag separation device, the upper portion of the gas and slag separation device is communicated with a gas collecting pipe communicated with the rectifying tower, and the bottom of the slag cavity is communicated with the magnetic separator. The waste and old tire colloidal particle cracking system and method are high in tire colloidal particle cracking rate, high in cracking object recycling rate, capable of achieving continuous production and low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of tire recycling, in particular to a cracking system for rubber particles of waste tires. Background technique [0002] Plastic and rubber are two widely used synthetic polymer compounds with many superior properties. The environmental pollution caused by their high consumption is becoming more and more serious. How to deal with and utilize these two kinds of waste polymer materials has aroused widespread concern in the world today. At present, many pyrolysis equipment for domestic waste and waste tires cannot be produced continuously, with high energy consumption, low pyrolysis rate and poor safety. [0003] Traverse the prior art of waste tire pyrolysis system, such as CN200920075659, CN201010183728, a prominent feature of the prior art is that the thermal energy in the system cannot be effectively utilized, such as the rubber particles before the waste tire enters the pyrolysis furnace, it usually need...

[0003] Traverse the prior art of waste tire pyrolysis system, such as CN200920075659, CN201010183728, a prominent feature of the prior art is that the thermal energy in the system cannot be effectively utilized, such as the colloidal particles before waste tires enter the pyrolysis furnace, usually have to be preheated before comparison Well, the existing technology is to use cold water to shower, and then set the heating step separately, and it does not propose that these two steps can be combined into one, and there are light oil and heavy oil produced after tire cracking, with a large amount of cracking at the same time There is nowhere to release the heat, which requires the cooperation of a large cooling device. The heat is completely wasted. At the same time, in addition to the preheating of the shower water, there are many places where the pyrolysis heat can be fully utilized. It is a pity to completely waste the pyrolysis heat.
