The invention relates to a recycling and hot air thermal-insulation system for asphalt flue gas. The system is characterized by comprising an asphalt tank, an electrical tar precipitator, an oil collecting tank, an aggregate preheating system, a heat pipe heat exchanger, a first flue gas water degradation box, a second flue gas water degradation box and a spiral heating pipe; and the flue gas discharge end of the top end of the asphalt tank is connected with the electrical tar precipitator, the discharge end of the electrical tar precipitator is connected to a high-temperature flue gas pipe ofthe aggregate preheating system through a pipe, the outlet end of the high-temperature flue gas pipe of the aggregate preheating system is connected to the heat pipe heat exchanger through a pipe, and the outlet end of the heat pipe heat exchanger is connected to the first flue gas water degradation box through a pipe. According to the system, the asphalt flue gas is used to recover tar, the taris put into a burner as a fuel to heat the asphalt tank to form the asphalt flue gas recycling system, so that the system reduces the emission of polluted gas, makes full use of combustible polluted gas, and saves energy.
Description
technical field [0001] The invention belongs to the technical field of bitumen flue gas recycling, and in particular relates to a bitumen flue gas recycling and hot air heat preservation system. Background technique [0002] When the asphalt is heated, a large amount of asphalt fume will be produced. There are many substances in the asphalt fume, such as carbocyclic hydrocarbons, cyclic hydrocarbon derivatives and other compounds, which will cause harm to human health. Pitch smoke contains a variety of polycyclic aromatic hydrocarbons, such as carbazole, benzanthracene, benzopyrene, etc., and most of these substances are carcinogenic and strong carcinogens, with particle sizes basically between 0.1 and 1.0 μm. The main way for these substances to cause harm to the human body is to attach to the floating dust below 8 μm and enter the human body through the respiratory tract. [0003] As bitumen contains high-boiling point mineral oil and a small amount of oxygen, sulfur and ...
