[0034] Example 2 When paving asphalt pavement, the portable asphalt fume collection device of the present invention is placed near the paving machine, and the smoke pipe 106 is aimed at the asphalt heating equipment or the paving area to collect the generated smoke. Since the smoke rises, the smoke pipe 106 should be adjusted to a 45-degree angle with the ground to effectively collect the rising smoke.

[0035] During the asphalt recovery process, the portable asphalt fume collection device of the present invention is moved to the side of the recovery equipment, and the smoke pipe 106 is aimed at the smoke generation point during the recovery process. According to the height and direction of the smoke generation point, the smoke pipe 106 usually needs to be adjusted to a horizontal or slightly upward angle (about 20°) to ensure that the smoke is effectively collected.

[0036] In an asphalt mixing plant, the portable asphalt fume collection device of the present invention is fixed near the mixing equipment, and the smoke pipe 106 is aimed at the smoke outlet to continuously collect smoke.
