Cracking equipment

Abstract

The invention discloses cracking equipment. The cracking equipment comprises a cracking cylinder; the periphery of the cracking cylinder is sleeved with the heating cylinder in a sealed mode, and the cracking cylinder rotates relative to the fixedly-arranged heating cylinder; the multi-spiral blade is fixed on the inner wall of the cracking cylinder, the multi-spiral blade comprises a plurality of single-spiral structures which are arranged in parallel and are spirally arranged along the axial direction of the cracking cylinder, and a spiral material channel is formed between every two adjacent single-spiral structures which are arranged in parallel. The heat transfer area in the cracking cylinder is greatly increased through the multiple spiral blades, materials are in contact heat transfer with the multiple spiral blades and the inner cylinder wall of the cracking cylinder at the same time, meanwhile, the multiple parallel spiral material channels evenly distribute the materials in the cracking cylinder, the thickness of the materials in the cracking cylinder is reduced, the situation that the materials are accumulated too thick, and the cracking efficiency is improved is avoided. Materials are fully and rapidly contacted with heat, the materials can be rapidly cracked, the heat transfer efficiency and the heat energy utilization rate are improved, and the cracking reaction is more facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a cracking equipment. Background technique [0002] Cracking equipment is a common production equipment in the chemical industry, which is used to thermally crack organic matter to obtain the required substances. The existing cracking equipment mainly includes a cracking drum and a heating drum. The heating drum is sleeved on the outer periphery of the cracking drum. The cracking drum rotates relative to the fixed heating drum. The organic material rolls and moves in the cracking drum. The cylinder wall of the cylinder is transferred to the organic materials in the cracking cylinder, and the materials will accumulate in the cracking cylinder. The heat transfer efficiency of the cracking equipment is low, which is not conducive to the cracking of organic matter. [0003] In summary, how to improve the heat transfer efficiency of the cracking equipment has become an urg...

Problems solved by technology

The existing cracking equipment mainly includes a cracking cylinder and a heating cylinder. The heating cylinder is set on the outer periphery of the cracking cylinder. The cracking cylinder rotates relative to the fixed heating cylinder. The organic material rolls and moves in the cracking cylinder, and the heat generated by the heating cylinder passes through the pyrolysis The wall of the cylinder is passed to the organic material in the cracking cylinder, and the material will accumulate in the cracking cylinder. The heat transfer efficiency of the cracking equipment is low, which is not conducive to the cracking of organic matter
