Abstract

The invention relates to a liquid asphalt granulation nozzle with a smoke sealing cover. The liquid asphalt granulation nozzle comprises a nozzle body, a connecting plate and the smoke sealing cover,wherein the nozzle body is fixed at the bottom of an asphalt distribution pipe through the connecting plate; the asphalt distribution pipe is arranged above a cooling water tank; a discharge port is formed in the bottom of the asphalt distribution pipe and communicates with a nozzle of the nozzle body; the smoke sealing cover is arranged on the outer side of the nozzle body; the top of the smoke sealing cover is fixedly connected with the connecting plate; and the bottom of the smoke sealing cover extends below the water surface of the cooling water tank. According to the liquid asphalt granulation nozzle, the nozzle body is detachably connected with the asphalt distribution pipe through the connecting plate, so that the replacement is convenient; and the smoke sealing cover is arranged onthe outer side of the nozzle body, and the lower end of the smoke sealing cover extends into water, so that asphalt smoke in the granulation process is prevented from entering the atmosphere to pollute the environment.

Description

technical field

[0001] The invention relates to the technical field of liquid asphalt molding, in particular to a liquid asphalt granulation nozzle with a fume sealing cover. 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] Most of the medium-temperature asphalt and modified asphalt products produced in China are sold in the form of solid, and a small amount of them are sold in the form of liquid asphalt.

[0004] At present, the asphalt forming unit of the coal tar processing system mostly adopts the asphalt solidification and cooling forming process, that is, the liquid asphalt is cooled and solidified by turbid circulating water. Se...
