Problems solved by technology
The stripping and flashing process of single furnace and single kettle also uses medium-temperature asphalt as raw material. The asphalt is heated in the tubular heating furnace, and then reacted in the reactor, and the reaction is completed in one step. time, to obtain modified asphalt products, but the product quality control is not as flexible as the double furnace and double kettle process

Embodiment Construction
[0029] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0030] Such as figure 1 As shown, a modified asphalt production system using a horizontal reactor according to the present invention includes a system consisting of 1# reactor 1, 2# reactor 2, 1# tube furnace 4, and 2# tube furnace 5. Double furnace and double kettle modified asphalt production system; also includes the modified still 3 on the secondary modified asphalt outlet pipeline of 2# reactor 2, and the 1# reactor 1, 2# reactor 2, modified Quality kettle 3 is a horizontal reactor.
[0031] A plurality of baffles 11 are arranged in the horizontal reactor along the asphalt flow direction.
[0032] The baffles 11 are composed of upper baffles and lower baffles arranged alternately and at intervals, the top of the upper baffles is fixedly connected with the top wall of the horizontal reactor, and the bottom of the upper baffles is connected w...

The invention relates to a modified asphalt production system and a process adopting horizontal reaction kettles. The system comprises a double-furnace double-kettle modified asphalt production system consisting of a 1 # reaction kettle, a 2 # reaction kettle, a 1 # tubular furnace and a 2 # tubular furnace, and also comprises a modification kettle which is arranged on a secondary modified asphalt outlet pipeline of the 2 # reaction kettle, and the 1 # reaction kettle, the 2 # reaction kettle and the modification kettle are all horizontal reaction kettles. According to the invention, baffle plates are arranged in the horizontal reaction kettles, so that materials can be fed and discharged orderly, and all the materials can be ensured to have the same and enough residence time; a conventional production system adopting a vertical reaction kettle can be replaced, and particularly, equipment configuration can be simplified at a full-flow discharging part of the reaction kettle.
Description
technical field [0001] The invention relates to the technical field of modified asphalt production, in particular to a modified asphalt production system and process using a horizontal reactor. Background technique [0002] Coal tar processing generally produces 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 the main downstream product of asphalt, which is mainly used in the electrolytic aluminum industry to produce prebaked anodes and prepare battery rods or electrode binders. [0003] At present, the production process of domestic modified asphalt mostly adopts thermal condensation polymerization method, which can be divided into kettle heating method and tube furnace heating method according to the heating method. [0004] The modified asphalt production process of kettle heating method is: using medium temperature asphalt as raw material, the outer surface of the reactor is ...
