Problems solved by technology

The disadvantage is that the one-step reaction requires high temperature and time control, and the product quality is difficult to control; the separation of asphalt and oil products by steam stripping will also produce a large amount of process wastewater
[0007] To sum up, there is currently no relatively complete modified asphalt production device in China that is suitable for various asphalt raw materials, energy-saving and environmentally friendly, and has excellent product quality

Abstract

The invention relates to a modified pitch production device. A pitch inlet of a flash column on the upper portion of a flash modification reaction still is connected with a raw material pitch conveying pipeline, and an oil gas mining opening of the flash column is connected with an oil gas condenser cooler. A pitch outlet of a lower reaction kettle is connected with a furnace tube inlet of a first tubular heating furnace, and a furnace tube outlet of the first tubular heating furnace is connected with a pitch inlet of a secondary modification reaction still. One path of a pitch outlet of the secondary modification reaction still is connected with a first pitch conveying pipeline on the upstream portion of the first tubular heating furnace, and the other path of the pitch outlet is connected with a pitch inlet of a fractionating tower. An oil gas mining opening of the secondary modification reaction still is connected with an oil gas inlet in the lower portion of the fractionating tower. An oil gas mining opening of the fractionating tower is connected with the oil gas condenser cooler, and a modified pitch mining opening of the fractionating tower is connected with a modified pitch outwards-conveying pipeline. A double-still two-step reaction method is adopted, the generation quantity of an alpha-component and a beta-component can be effectively controlled, and the product quality is controllable. The process is simple and easy to carry out, and the modified pitch production device saves energy, and is environmentally friendly and suitable for various pitch raw materials.

Description

technical field [0001] The invention relates to the technical field of asphalt production, in particular to an energy-saving and environment-friendly modified asphalt production device suitable for various asphalt raw materials. Background technique [0002] Coal tar processing generally produces about 50% to 60% of asphalt, which is a bulk product of tar processing. The larger the processing scale, the more asphalt output. Modified asphalt is currently the main downstream product of asphalt, which is mainly used in the electrolytic aluminum industry to produce prebaked anodes, and to prepare battery rods or electrode binders. [0003] At present, domestic production of modified asphalt mostly adopts kettle-type thermal condensation polymerization process. This process uses medium-temperature asphalt as raw material, and achieves the purpose of asphalt modification by controlling a certain reaction residence time and appropriate reaction temperature in a reactor directly he...
