Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to an asphalt production tail gas treatment device which can utilize waste heat. Background Art

[0002] Asphalt is a dark brown complex mixture of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, mostly in the form of liquid or semi-solid petroleum. The surface is black and soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic gelling material that is waterproof, moisture-proof and anti-corrosive. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt: among them, coal tar asphalt is a by-product of coking. Petroleum asphalt is the residue after crude oil distillation. Natural asphalt is stored underground, some of which form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in industries such as coatings, plastics, rubber, and paving roads.

[0003] At present, some waste gas is generated during asphalt processing and production on the market. The waste gas is treated by filtration and sterilization, adsorption purification, flue gas washing and digestion and absorption purification. In actual use, when the flue gas from asphalt production is subjected to flue gas washing, liquid is usually used to spray the exhaust gas directly through a nozzle. This method is prone to spraying dead corners at the inner edge of the cylinder. At the same time, most of the exhaust gas is sprayed directly with cold water, which makes it impossible to effectively utilize the waste heat in the exhaust gas. Utility Model Content
