Abstract

A pyrolysis reactor is provided. The pyrolysis reactor includes a pyrolysis reactor main body (4) and a premixing device (1) used for premixing a material and a heat carrier and conveying a mixture formed by premixing the material and the heat carrier to the pyrolysis reactor main body (4). A flowing space allowing a gas generated when the material and the heat carrier are premixed to flow is disposed in the premixing device (1), and is communicated with the pyrolysis reactor main body (4) so as to lead the gas generated in the premixing device (1) to the pyrolysis reactor main body (4). The pyrolysis reactor can achieve uniform mixing between the solid heat carrier and the material, reduces the air impermeability level of the premixing device and overcomes a problem of pyrolysis gas backward flowing.

Description

technical field

[0001] The invention relates to a pyrolysis reactor, in particular to a novel pyrolysis reactor with forced premixing. Background technique

[0002] According to the heating method, the pyrolysis process can be divided into two types: external heat type and internal heat type. The thermal efficiency of the external heating type is low, the material (such as coal) is heated unevenly, and the secondary decomposition of volatile products is serious; the internal heating type process overcomes the shortcomings of the external heating type, and the heat is directly transferred to the material by means of a heat carrier, and the heated material generates heat. solution reaction. According to the different heating medium, the internal heating process can be divided into gas heat carrier pyrolysis process and solid heat carrier pyrolysis process. The gas heat carrier pyrolysis process usually introduces the flue gas produced by fuel combustion into the pyrolysis ch...
