[0002] After the asphalt pavement reaches its service life, it is often necessary to recycle pavement asphalt waste. In the prior art, it is often directly processed into new asphalt concrete after adding a rejuvenating agent to the old asphalt. If the asphalt pavement waste needs to be recycled After the asphalt is separated and used for other purposes, the asphalt waste needs to be heated. However, in this production process of asphalt heating and recycling, large high-temperature smoke and dust will be generated due to the heating of the asphalt.

The invention discloses a dust removal and recovery device for asphalt production, which comprises a cylindrical shell, a heating cavity and a waste gas cavity are arranged in the shell, a feeding port communicated with the heating cavity is arranged on the shell, the dust removal and recovery device is characterized in that the waste gas cavity comprises a front waste gas cavity and a rear waste gas cavity, and the front waste gas cavity is positioned above the heating cavity. A gas inlet of the front waste gas cavity is communicated with the upper end of the heating cavity. The rear waste gas cavity is formed in the shell, an annular cooling water cavity is formed between the rear waste gas cavity and the front waste gas cavity, and a gas outlet of the front waste gas cavity is communicated with the rear waste gas cavity through a plurality of branch gas pipes. And each branch gas pipe is accommodated in the cooling water cavity. According to the dust removal and recovery device for asphalt production, high-temperature smoke dust generated by heating can be well cooled and dedusted in the process of heating and recycling asphalt waste, so that the dedusting effect is achieved.
Description
technical field [0001] The invention relates to the technical field of asphalt regeneration and recovery, in particular to a dust removal and recovery device for asphalt production. Background technique [0002] After the asphalt pavement reaches its service life, it is often necessary to recycle pavement asphalt waste. In the prior art, it is often directly processed into new asphalt concrete after adding a rejuvenating agent to the old asphalt. If the asphalt pavement waste needs to be recycled After the asphalt is separated and used for other purposes, the asphalt waste needs to be heated. However, in this production process of asphalt heating and recycling, large high-temperature smoke and dust will be generated due to the heating of the asphalt. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent: to provide a dust removal and recovery device for asphalt production, which ...
