[0002] Highway asphalt waste recycling refers to the collection, processing and reuse of waste asphalt mixtures during highway construction and maintenance. These wastes mainly come from asphalt concrete milled off during the renovation, widening and reconstruction of old roads. When recycling highway asphalt waste, a pyrolysis device is required to extract the effective ingredients in the waste asphalt. The separated oil can be processed into new asphalt products.

[0003] After searching the Chinese patent "A pyrolysis device for recycling and reusing asphalt concrete waste", the publication number is "CN217419215U". This patent sets a dust suction mechanism. The dust generated when the asphalt concrete waste is crushed enters the filter box along the suction pipe, the fixed ring and the gas pipe under the action of the vacuum fan. The filter net performs preliminary filtration of impurities in the gas, and the activated carbon filter layer performs secondary filtration of impurities in the gas. The filtered gas is discharged from the filter box through the air outlet. In this way, the dust is treated and the health of the workers and the environmental hygiene are effectively protected. However, the device is not convenient for filtering and purifying the gas generated by the pyrolysis of asphalt waste, which reduces the use effect of the device.
