[0002] During the production of asphalt mixture, it is necessary to heat the asphalt in the asphalt heating tank to maintain a fluid state and introduce it into the mixer. The aggregate conveying system introduces the hot aggregate into the mixer and mixes it with the asphalt. There are many pollution sources in the mixing production. The asphalt heating tank is in During the heating process, the asphalt evaporates, which puts the tank under pressure. In order to reduce the pressure of the tank, the gas in the tank needs to be led out, but this is easy to cause pollution, and after the mixing is completed, the mixer dumps the asphalt mixture into the loading vehicle, which will cause a lot of damage. smoke leak

Embodiment Construction
[0039] The present invention will be further described below in conjunction with accompanying drawing:
[0040] Such as Figure 1-14 As shown, the present embodiment provides a waste gas treatment line of an asphalt mixing plant. The mixing plant has a mixer 1, an asphalt heating tank 2 connected to the mixer 1, and an aggregate conveying system 3. The asphalt heating tank 2 is used to heat the asphalt and The asphalt is sent into the mixer 1, and the aggregate conveying system 3 is used to send the aggregate into the mixer 1. The processing line includes a dust treatment system, a flue gas treatment system 5, and a heating tank flue gas treatment device 21. The asphalt heating tank 2 heats When the bitumen in the tank body 22 volatilizes, the pressure of the tank body 22 increases, and the heating tank flue gas treatment device 21 is installed on the tank body 22 of the asphalt heating tank 2, and the gas is discharged and processed through the heating tank flue gas treatment...
