Abstract

The present invention discloses asphalt fume cleaning process and apparatus. The asphalt fume cleaning process includes sucking asphalt fume with one induced draft fan, condensing for the first time in the first condensator and condensing for the second time in the second condensator to convert asphalt component into tar, separating in a tar-water separator, pumping the tar to one tar storage tank and exhausting waste gas to atmosphere. The asphalt fume cleaning apparatus includes one induced draft fan, one first condensator, one second condensator, one tar-water separator, one tar pump and one tar storage tank connected together. The present invention has reliable technological principle, simple structure low running cost and low fault rate.

Description

Technical field: [0001] The invention relates to a purification method and device, in particular to a method and device for purifying asphalt flue gas. Background technique: [0002] Nowadays, the asphalt fume produced in the process of asphalt melting, paste making and molding in the carbon industry often brings in part of the dust raised when it is collected by negative pressure method. Therefore, the exhaust gas passing through the purification system not only contains asphalt fume, but also It also contains a certain amount of dust soaked in tar. Depending on the core equipment used, the purification method is also different. The most commonly used purification methods are: [0003] (1) Electric tar capture method, that is, under certain temperature conditions, asphalt smoke is captured by the action of an electric field and turned into tar. Using this method, the captured tar can be stored centrally for other uses such as fuel. When the equipment is in good conditio...
