Abstract

A modified pitch preparation system comprises a reaction kettle, a heating furnace, a modification tower, a modified pitch intermediate tank and a pitch forming device, a plurality of sections of steam heating coil pipes are arranged in a jacket of the reaction kettle, the length of the steam heating coil pipes is 30-50 m, and the steam heating coil pipes are used for preheating the reaction kettle when the system is started. And the reaction kettle is subjected to heat preservation when the system is shut down. By improving the steam heating coil of the reaction kettle, a large amount of condensed water can be prevented from being formed at the tail end of the steam heating coil, and the heating effect of the steam heating coil on the reaction kettle can be effectively guaranteed.

Description

technical field [0001] The invention relates to a modified asphalt preparation system. Background technique [0002] Coal tar processing generally produces about 50% to 60% of medium-temperature pitch, which belongs to the bulk product of tar processing. Modified pitch is the main downstream product of medium-temperature pitch at present, and is mainly used in the electrolytic aluminum industry to produce prebaked anodes and prepare battery rods or electrode binder. [0003] The preparation process of modified asphalt in the prior art is relatively mature. For example, in the invention patent application of application number 2020113486117, the name is a kind of modified asphalt production system and its cleaning process by tubular furnace heating method, and a tubular type is described in detail. Furnace heating modified asphalt production system; and, the Chinese invention patent application with the patent application number 2015105008517 records a process and device for...
