Problems solved by technology

Moreover, the vicinity of the above-mentioned inlet and outlet may also cause problems such as poor thermal decomposition reaction of polymer waste, large molecular weight distribution of pyrolysis gas generated, deviation in the composition of the recovered oil, and quality degradation.
Moreover, if the temperature of the gas near the gas outlet of the above-mentioned thermal decomposition furnace drops below 250°C, it will not be able to provide the necessary heat for subsequent rectification of the recovered oil after condensation in the oil recovery device, resulting in a low oil recovery rate, Problems such as deviation of oil composition and quality decline

Abstract

The invention relates to the technical field of environment, in particular to a high molecular waste oiling recovery system. The system comprises a heat exchanger, a thermal decomposition furnace, anouter heating furnace, a thermal decomposition device, an oil ingredient recovery device and a circulation pipeline, wherein the heat exchanger is used for heating oxygen-free gas; high molecular waste is accommodated inside the thermal decomposition furnace; an outer heating furnace is used for heating the thermal decomposition furnace from the outside; the thermal decomposition device is used for generating thermal decomposition gas through performing thermal decomposition on the high molecular waste in direct contact with the oxygen-free gas heated by the heat exchanger in the oxygen-free state; the oil ingredient recovery device is used for cooling oil ingredients obtained by cooling, recovering and condensing the thermal decomposition gas generated by the thermal decomposition device;the circulation pipeline is used for using the rest gas after the oil ingredient recovery by the oil ingredient recovery device as oxygen-free gas so that the gas can realize the circulation in the heat exchanger. The system has the advantages that the adverse influence due to mixing of solid ash ingredients or generation of nitric oxides can be avoided; the oil ingredients with coincident ingredients and stable quality can be recovered; in addition, the system has high recovery rate.

Description

technical field [0001] The invention relates to the field of environmental technology, in particular to an oil recovery system for polymer waste. Background technique [0002] Materials such as plastics, rubber, and synthetic fibers have important application values ​​in various sectors such as industry, agriculture, and national defense. In many sectors, the level of technology is often measured by the application of polymer materials. Therefore, the development of polymer materials Although it has only a few decades of history, its development is extremely rapid. In the early 1990s, the world's output of plastic alone exceeded 100 million tons. In the past 20 years, the development of polymer materials in China has also been very rapid. By 2010, the total production scale of the three major domestic synthetic materials (synthetic resin, synthetic rubber, and synthetic fiber) has ranked first in the world. Since most of these synthetic materials cannot be naturally degrade...
