System and method for modifying coal tar and medium-temperature asphalt with coal-to-liquid oil residues

Abstract

The invention discloses a system and method for modifying coal tar and medium-temperature asphalt with coal-to-liquid oil residues. The system comprises a stirring-distillation integrated machine, wherein the stirring-distillation integrated machine comprises a machine box, and the lower middle portion of an inner cavity of the machine box is rotationally connected with a conical heating barrel through a supporting base fixedly connected with a side wall. According to the system and method for modifying coal tar and medium-temperature asphalt with coal-to-liquid oil residues in the invention,a screening mechanism is arranged in the machine box, so coal cinder can be screened; the conical heating barrel is arranged and matched with a stirring shaft and stirring rods, so materials can be stirred and mixed; meanwhile, the conical heating barrel can be used for heating and distilling; due to the conical arrangement of the conical heating barrel, residues in a previous procedure can be thrown out in the process of high-speed rotating, so a next procedure is prevented from being influenced; more than one set of stirring and mixing equipment and distillation tower are integrated in one set of equipment, so equipment cost and maintenance cost are reduced, and an occupied area is reduced.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a system and a reforming method for reforming coal tar and medium-temperature asphalt from coal oil residue. Background technique [0002] In recent years, the transformation of coal into oil often appears in people's lives. This is another great progress in human science. The application of high technology enables us to convert coal into oil; processed products. From a chemical point of view, coal-to-oil is actually an important part of coal chemistry, known as coal chemical industry. The chemical process of coal chemical industry and petrochemical industry is different. Coal chemical industry belongs to the carbon-chemical part. Coal is used as raw material, and coal gas containing one carbon is used as raw material to produce related multi-carbon compounds, and sometimes it is the processing process of polymer compounds. Petrochemical industry is the process ...
