Feeding system for granulation finished product of waste tire pyrolysis carbon black

Abstract

The invention discloses a feeding system for a granulation finished product of waste tire pyrolysis carbon black. According to the invention, a dense-phase pressure conveying feeding device enables carbon black to enter a feeder through pressurization by a pressure conveying tank to ensure the material extrusion is strict and to improve the stability of the feeder. At the same time, the dense phase conveying speed is slow, the conveying distance is long, and secondary damage caused by material transportation is avoided. A gas source filtering device can automatically adjust the conveying air pressure according to the characteristics of a conveyed material to ensure the reliability of system operation, and the filtering device improves the gas source cleanliness and prevents impurities fromreducing transport performance. The core of the invention lies in that a conveying mode is reasonably selected according to the characteristics of the conveyed material, that is finished carbon black, wherein continuous feeding the granulation finished product of carbon black is achieved by using dense-phase conveying with a low flow rate and a high pressure, thereby greatly reducing the carbon black conveying failure rate, and ensuring the physical properties of carbon black. All links of the whole system are equipped with automatic detection components to cooperate with a control system toachieve automatic stable operation of the feeding system for the granulation finished product of carbon black.

Problems solved by technology

[0003] The pyrolysis of waste tires can produce pyrolysis gas, carbon slag, and steel wire. The pyrolysis gas can be recovered through condensation to obtain pyrolysis oil, and the non-condensable gas can be reused as combustible gas; the generated carbon residue is the pyrolysis carbon black of waste tires. After carbon black is processed into finished carbon black, the problem of collection and transportation of finished carbon black has not been effectively solved

[0004] Traditional pyrolysis finished carbon black is conveyed by belt conveying, hoist conveying, and inclined conveying. This kind of conveying method has many transmission parts, consumes a lot of energy, and has poor sealing and conveying performance, which may easily cause carbon black leakage and pollute the environment.

In recent years, powder pneumatic conveying technology has been applied to carbon black conveying, but because technicians failed to analyze the characteristics of powder pneumatic conveying technology in detail, resulting in the powder concentration, conveying speed, conveying Unreasonable pressure and other control will destroy the physical properties of the finished carbon black
