Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to an asphalt flue gas purification device. Background Art

[0002] In many industries in the metal and chemical fields, a large amount of asphalt fume is generated during the production process. For example, in the electrolytic aluminum industry, carbon dust and asphalt fume are generated in the feeding system, discharging system, kneading machine and grinding system of the anode calcining workshop; asphalt fume is generated in the molding section; and the residual anode treatment section is even more smoky. In order to protect the environment and the health of the workers, the asphalt fume needs to be purified.

[0003] The existing asphalt fume purification is to remove the asphalt fume through an asphalt fume removal tank. The specific principle is: a trough-shaped container (i.e., asphalt fume removal tank) is used, engine oil is added inside, and the asphalt fume enters from the bottom of the trough-shaped container through a pipeline, and is discharged from the top after being purified by the engine oil, thereby being purified.

[0004] However, in the existing asphalt fume purification process, the asphalt fume purification effect is not good, and yellow smoke is often discharged into the air. In addition, if the asphalt fume is introduced at a larger flow rate, the purification is incomplete, and most of the fume is discharged into the air, causing environmental pollution. Moreover, the top of the existing asphalt fume removal tank is open. When the flow rate of asphalt fume is large, it often overflows with engine oil and falls on the top of the asphalt fume removal tank below, resulting in a layer of oil on the top that is difficult to clean.
