The beneficial effect of this scheme is: in the temperature conduction area of the high-temperature section refrigerating assembly, the disturbance of airflow is formed around the flow deflector by utilizing the difference of the aperture of the circular flow guide hole, so that the contact probability and the retention time of the incoming flow and the flow deflector are increased, and the primary cooling is carried out, thereby achieving the cooling of the incoming flow and the collection of tar therein. In the temperature conduction area of the medium-temperature section refrigerating assembly, on one hand, the change of the aperture of the flow guide hole in the shape of the truncated cone can be utilized to form turbulent flow so as to increase the contact between the incoming flow and the flow guide sheet; on the other hand, the gradually increased or decreased aperture forms a structure of a spray pipe, so that the incoming flow is decelerated or accelerated in the flow guide hole, and then a turbulent flow is formed at the outlet of the incoming flow of the medium-temperature section temperature guide sheet, and the cold exchange and tar collection are further enhanced; meanwhile, the conical holes have larger contact area compared with the circular holes, so that the probability of condensing and collecting tar in the incoming flow is improved to a certain extent; in addition, tar cooled in the incoming flow or particles leaked from the reactor can cause the blockage of the heat conducting plate, and for the frustum cone holes with variable hole diameters, the frustum cone holes with gradually reduced hole diameters can accelerate the incoming flow passing through, so that the blockage is avoided; and the cone frustum hole with smaller inlet aperture can reduce the entering of the leaked particles in the reactor to a great extent, and the gradually-expanded aperture also enables the collected tar to be more effectively adhered without being accumulated.
