Problems solved by technology

[0002] At present, when asphalt is heated or subjected to high temperature treatment, asphalt fume will be produced, which contains benzopyrene in addition to common air pollutants such as carbon monoxide, sulfur dioxide, and nitrogen oxides, and is discharged into the atmosphere. The content of pyrene can reach 1.3-2 mg / m3, so if the asphalt smoke volatiles are directly discharged into the atmosphere, it will cause air pollution

Abstract

The invention discloses an environment-friendly asphalt storage system and belongs to the technical field of asphalt fume treatment. The environment-friendly asphalt storage system comprises a heavy oil tank and asphalt tanks. The heavy oil tank and the asphalt tanks are arranged in parallel connection. The environment-friendly asphalt storage system further comprises an asphalt fume cooling absorption device, an oil unloading device and a pump set. The upper ends of the heavy oil tank and the asphalt tanks are connected with the asphalt fume cooling absorption device through a first pipeline. Asphalt fume generated when the heavy oil tank and the asphalt tanks are heated enters the asphalt fume cooling absorption device, and a condenser in the asphalt fume cooling absorption device captures small granules in the fume and purifies the granules before the granules are discharged; one ends of the heavy oil tank and the asphalt tanks are connected with safety pressure devices correspondingly, and when pressure in the heavy oil tank and the asphalt tanks exceeds a set pressure value, the safety pressure devices control the pressure in the tanks to be released; and the other ends of the heavy oil tank and the asphalt tanks are connected with a second pipeline, and the second pipeline is connected with input equipment, the oil unloading device and the pump set. According to the environment-friendly asphalt storage system, an innocent treatment process is achieved, harmful ingredients are degraded, and fume emission is made to meet relevant standards.

Description

technical field [0001] The invention relates to an asphalt environment-friendly storage system, belonging to the technical field of asphalt flue gas treatment. Background technique [0002] At present, when asphalt is heated or subjected to high temperature treatment, asphalt fume will be produced, which contains benzopyrene in addition to common air pollutants such as carbon monoxide, sulfur dioxide, and nitrogen oxides, and is discharged into the atmosphere. The content of pyrene can reach 1.3-2 mg / m3, so if the asphalt smoke volatiles are directly discharged into the atmosphere, it will cause air pollution. [0003] According to the national emission standard for asphalt fume GB / 16297, asphalt fume mainly exists in the form of tar fine mist particles of 0.1-1.0um. The purification treatment is to capture these tiny particles as much as possible to make the asphalt fume Emissions meet relevant standards. Contents of the invention [0004] In view of the above-mentioned...
