Description

Technical Field

[0001] This utility model relates to the field of data collection equipment technology, specifically a portable asphalt fume collection device. Background Technology

[0002] Asphalt mixture pavement has good road performance and is therefore widely used in the paving of high-grade roads. However, the production and paving process of asphalt mixtures generates a large amount of fumes, the main harmful components of which are volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). Asphalt fumes not only pollute the surrounding environment and endanger the health of construction workers, but also reduce visibility during tunnel construction. Therefore, in highway engineering construction, it is necessary to address the issue at its source, adhering to both short-term and long-term solutions, to reduce fumes emissions during road paving and to further promote the construction of green highways.

[0003] The mixing temperature of hot-mix asphalt mixtures is typically between 140 and 180°C. At this temperature, asphalt produces a large amount of fumes. Asphalt fumes mainly consist of volatile organic compounds and fine particulate matter (PM). Gas chromatography-mass spectrometry analysis revealed over 200 organic pollutants in asphalt fumes, with 81 of them present in high concentrations, primarily polycyclic aromatic hydrocarbons (PAHs). Some asphalt pollutants are carcinogenic and toxic, and long-term exposure to asphalt fumes can cause adverse health effects.

[0004] Existing on-site asphalt fume collection devices have some shortcomings in use. They are cumbersome to operate, require two or more people to complete the collection, and have low collection efficiency. We propose a portable on-site asphalt fume collection device. Summary of the Invention
