Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a device for removing asphalt smoke from tail gas of an anode baking furnace using a turbocharged turbulator. Background Art

[0002] Asphalt fume is primarily generated by the heating and combustion of asphalt. This includes industrial thermal processes such as coking and oil refining, as well as processes that heat asphalt to produce asphalt products, such as road paving, house repair, or anti-corrosion coatings. During these processes, volatile compounds in the asphalt are released into the atmosphere, forming a complex mixture of solid and liquid particles and vaporous organic matter, which becomes an atmospheric pollutant. The composition of asphalt fume is extremely complex and varies depending on the source of the asphalt. It primarily includes volatile organic compounds and some inorganic components, such as carbon dioxide, carbon monoxide, sulfides, and nitrogen oxides, as well as harmful substances such as polycyclic aromatic hydrocarbons and some heavy metals.

[0003] Current methods for treating asphalt fume include: incineration, which burns hydrocarbons, combustible carbon powder, and tar in the flue gas to decompose them into CO and H₂. However, this method has high combustion temperatures and requires a certain concentration of the combustible materials for combustion. This requires strict combustion time control, which can easily lead to incomplete combustion and secondary pollution, resulting in high investment and operating costs. Absorption, in which asphalt fume is brought into direct contact with an organic liquid (washing oil) to precipitate tar particles and soot, thereby purifying the asphalt fume. However, this treatment process produces wastewater, causing secondary pollution, and is inefficient, leading to numerous problems with the flue gas purification system. Electrostatic capture, using high-voltage electrostatics (electrostatic precipitators), captures tar. A high DC voltage is applied between the corona electrode (negative electrode) and the precipitation electrode, generating corona electricity and ionizing the flue gas into a large number of positive and negative ions. As the positive and negative ions migrate toward the corona electrode and precipitation electrode, they encounter tar droplets, becoming charged and attracted to the electrodes, thereby being removed. Electrostatic capture has certain requirements for flue gas concentration and the resistivity of the soot. This method is widely used in the treatment of asphalt flue gas; the filtration method uses filter bags to filter and purify asphalt flue gas, but because the characteristic of asphalt flue gas is that it is easy to adhere, the liquid organic volatiles and tar in the flue gas are easy to adhere to the surface of the filter bag to solid asphalt over time, clogging the filter bag, increasing the resistance of the dust removal system, affecting the purification and filtration effect, and the filter bag life is not long.

[0004] For example, Chinese Patent C211713587U discloses an environmentally friendly asphalt mixing plant that effectively reduces smoke pollution from finished asphalt. The plant comprises a main building, a finished product silo located at the bottom of the main building, a discharge port at the bottom of the silo, and a discharge passage outside the silo for loading trucks. A roof is provided above the discharge passage, the side of the roof proximate the silo being fixedly connected to the outer wall of the silo. An air collecting port is provided on the top wall of the roof, and an exhaust fan is provided above the air collecting port. The exhaust fan pipe is connected to an asphalt smoke purification device. The asphalt smoke purification device comprises a smoke conveying pipe connected to the exhaust fan at one end and a drying drum connected to the other end of the smoke conveying pipe. A burner is fixedly connected to the end of the drying drum proximate the smoke conveying pipe, and the burner's combustion head extends into the drying drum. This utility model has the advantages of effectively removing asphalt smoke and reducing the environmental pollution caused by asphalt smoke.

[0005] However, the combustion time of this device is strictly controlled, which easily causes incomplete combustion and secondary pollution, and the investment and operation costs are very high.
