Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pyrolysis gas treatment, in particular to a reboiling reforming device. Background Art
[0002] During the process of tire pyrolysis and oil refining, after the waste tires are pyrolyzed by the waste tire oil refining equipment, oil gas and carbon black steel wire can be obtained. In this process, the proportion of combustible oil gas is relatively high, reaching about sixty percent. After leaving the pyrolysis furnace, the combustible oil gas is input into the post-treatment system. The main function of the post-treatment system is to separate the pyrolysis oil gas into pyrolysis oil and pyrolysis gas through condensation and other links. The pyrolysis oil can be distilled and purified to obtain oil products such as gasoline and diesel commonly used in daily life. The condensation of the pyrolysis oil gas is divided into two stages. After entering the primary condenser, heavy oil is obtained. The heavy oil can be catalytically pyrolyzed to obtain products such as diesel. The uncondensed gas enters the secondary condenser and is liquefied to obtain light oil, which can be directly used after purification. After two-stage condensation, the oil gas separation is completed, and pyrolysis oil and pyrolysis gas are obtained. The pyrolysis gas is transported to a desulfurization and purification tank for desulfurization, and then enters an activated carbon purification tank for carbon removal and purification treatment, so as to obtain usable combustible gas. After passing through the gas holder, it enters the compressed air gas. The compressed air system will compress the purified combustible gas. The compressed combustible gas will be transported to a liquefied gas condensation tank for storage, and the non-compressible combustible gas will be directly transported to a gas tank for storage, ready to be burned at any time.
