Background The wide use of agricultural films causes serious white pollution, and the company initiates a recycling mode of pyrolysis oil production of the mulching films, so that the recycling method is another path for realizing the recycling of waste mulching films. The recovered waste mulch needs to enter the pyrolysis furnace in a block state to save space. However, when pyrolyzing, the outer layer of the partially-agglomerated mulching film is subjected to hot melting and is coated with the inner mulching film, so that the inner mulching film is not heated enough and cannot be subjected to full hot melting pyrolysis, the pyrolysis rate and the oil yield are obviously reduced, and the produced carbon black contains more mulching film melting particles which are not fully pyrolyzed. At present, a horizontal cracking furnace generally adopts steel balls to strike and crush caking materials, so that the cracking sufficiency can be ensured, but a vertical cracking furnace is limited by structure, cannot apply a steel ball crushing mode, and the difficulty of caking mulching film crushing is not solved. The existing crushing technology cannot be adapted to vertical pyrolysis equipment, and is difficult to realize efficient and full pyrolysis of the waste mulch film, so that the application and popularization of the vertical pyrolysis furnace in the field of waste mulch film recycling are restricted.
