Title:
CONVEYING AND COOLING METHOD FOR HIGH-TEMPERATURE SOLID PRODUCT OBTAINED AFTER WASTE PLASTIC CRACKING
Document Type and Number:
WIPO Patent Application WO/2022/067883
Kind Code:
A1
Abstract:
A conveying and cooling method for a high-temperature solid product obtained after waste plastic cracking. The conveying and cooling method comprises the following steps: 1) primary cooling: enabling the high-temperature solid product obtained after waste plastic cracking to enter a first spiral conveying apparatus (100) for cooling; 2) secondary cooling: enabling the solid product to enter a second spiral conveying apparatus (200) from the first spiral conveying apparatus (100) by means of a shifting device (500) for cooling; 3) tertiary cooling: enabling the solid product to enter a third spiral conveying apparatus (300) for cooling; and 4) storing and discharging: enabling the solid product to enter a storage tank (400), opening an electric valve (41), and discharging residues. High-temperature cracking residues are cooled in a staged mode by means of multi-stage spiral conveying; low-temperature discharging and conveying of the high-temperature residues are achieved; the residues are compressed and stacked in a spiral conveying process; self-sealing of the apparatus is achieved by means of natural gravity stacking of the residues; cracking gas is prevented from escaping; external gas is prevented from entering; and the sealing method is simple, effective and environmentally friendly.
