[0002] Impregnated asphalt is a special asphalt material specially used for impregnating carbon products. In the heat treatment process of producing impregnated asphalt, a tubular furnace is required to provide a heat source to separate the light and heavy components in the raw asphalt and modify the heavy component asphalt. Tubular furnaces usually use coke oven gas as fuel, but the calorific value of coke oven gas is low, and the reaction is slow during the temperature increase process of the tubular furnace, which affects process adjustment and product quality stability.
[0003] In addition, in the tubular furnace, the raw asphalt is heated to a relatively high temperature, usually exceeding its softening point; during the heating, evaporation and modification of the asphalt, some light components and volatile substances will evaporate into the air to form asphalt fume; asphalt fume may contain a variety of harmful substances, such as polycyclic aromatic hydrocarbons, benzopyrene, etc., which cause harm to the human body and the environment; therefore, when treating asphalt fume, spray towers, incinerators and other equipment are often used to treat the asphalt fume.
[0004] However, when the existing spray tower is in use, the asphalt smoke has a short contact time with the spray liquid in the spray tower during the process of entering the spray tower, which makes the dust and light oil in the asphalt smoke difficult to dissolve in the spray water, easily causing blockage of subsequent pipelines and affecting the treatment of asphalt smoke.
