Description

Asphalt mixture stirring equipment and process for adding reclaimed materials in high proportion

Technical Field

The invention belongs to the technical field of asphalt mixture stirring, and particularly relates to asphalt mixture stirring equipment and technology for adding reclaimed materials in a high proportion.

Background

With the development of China asphalt pavement engineering, asphalt pavement for early construction and traffic has mostly entered major and middle repair stages, and waste asphalt mixture (Reclaimed Asphalt Pavement, namely RAP) generated by the asphalt pavement is increasing year by year. Because the China asphalt pavement regeneration technology starts later, the policy is not strong, and the regeneration technology is gradually formed at present. There are two application forms of the heat regeneration technology commonly used in China at present: one is in-situ, and the other is in-plant. The in-situ heat regeneration equipment is also called a regeneration train, and is characterized by having a small influence on traffic due to the speed of the regeneration treatment of the pavement, but has the defects of limited thickness of the treated pavement (being suitable for preventive maintenance), serious environmental pollution caused by waste gas emitted from the pavement in the heating process and expensive equipment. The plant-mixed heat regeneration equipment is a fixed asphalt mixture regeneration station which can be matched with a stirring station for use. The method has the advantages of strong quality controllability of finished products, simple operation and lower equipment purchasing cost. According to the related data, the plant mix thermal regeneration mode is introduced to have the highest utilization rate in the global scope, is the only mode with the mixture performance being comparable with that of a new material in a plurality of regeneration modes, and is the main stream regeneration mode of China at present according to the current use condition of China.

Because the asphalt high-speed pavement which is built in traffic at early stage enters a large maintenance period, a large amount of old asphalt milling materials are generated. The use of a large amount of recycled asphalt materials can reduce the cost along with the deep concept of energy conservation and environmental protection, but at the same time means that the stirring equipment needs more maintenance and has higher requirement on wear resistance. In the past, the stirring equipment mainly uses raw aggregate plus new powder and then adds heated asphalt to carry out hot stirring, and along with the increase of highway reclaimed materials, some reclaimed materials are slowly added to mix with the raw aggregate to produce the required asphalt mixture. The traditional stirring equipment, the mixing tank at the main building part is mainly used for mixing new materials, and regenerated materials are added into the mixing tank as auxiliary towers through a chute, so that the percentage of the reclaimed materials can be limited.

Because asphalt mixture stirring equipment generates a large amount of waste gas, mainly asphalt flue gas and dust, in the production process of hot-mix mixtures. Wherein, the high-temperature asphalt can generate a large amount of asphalt smoke at the discharging position of the exhaust port of the asphalt tank and the stirring pot; dust generated in the production processes of batching, feeding, stirring, discharging and the like is drifting everywhere, so that not only can the health of operators be seriously influenced, but also serious pollution can be caused to equipment and surrounding environments, such as haze, and the life of surrounding residents is influenced. In order to prevent the exhaust gas from harming the health of people and polluting the surrounding environment, the exhaust gas must be effectively restrained, and the air quality of the surrounding environment is improved.

Wherein, the asphalt fume is characterized by easy adhesion and inflammability and explosiveness above a certain temperature. In the process of collecting, conveying and eliminating smoke of asphalt flue gas, liquid-solid asphalt is easily adhered to the surfaces of pipelines and equipment; the solidified asphalt is difficult to remove, and often causes pipeline blockage and equipment damage, so that the system cannot normally operate. In addition, the asphalt smoke components are extremely complex and vary with asphalt sources; the asphalt fume contains solid and liquid particles formed by condensing volatile components of asphalt and vapor state organic matters, and part of the organic matters are high molecular polymers, so that serious environmental pollution is caused. The smoke contains various organic matters including carbon cyclic hydrocarbon, cyclic hydrocarbon derivatives and other compounds, which have a harmful effect on human health, the asphalt smoke contains various polycyclic aromatic hydrocarbon substances such as benzopyrene, benzanthracene, carbazole and the like, most of the substances are cancerogenic and strong cancerogenic substances, the particle size is between 0.1 and 1.0 mu m, the minimum particle size is only 0.01 mu m, the maximum particle size is about 10.0 mu m, the substances are various cancerogenic substances represented by 3, 4-benzopyrene, and the substances can be attached to fly ash below 8 mu m, are absorbed into human body through respiratory tract and harm human health.
