| description | The invention discloses multiphase flow buffering equipment for a heat exchanger of a black water system in the coal chemical industry field. A black water multiphase flow medium containing hard coalpowder particles enters an expanded pipe section through a connecting pipe, a transverse speed component is generated under the flow-guiding effect of an expanded pipe, the medium perpendicular speedis decreased, and shear abrasion of the multiphase flow medium to a straight wall section of a buffering cylinder and impact abrasion of the multiphase flow medium to a flange blind plate at the cylinder bottom are reduced. Nilcra zirconia can be sprayed to the inner wall of the expanded pipe section, and the abrasion-resistance performance of the inner wall of the expanded pipe section is effectively improved. The black water multiphase flow medium containing the hard coal powder particles flows to a ceramic plate at the cylinder bottom to be deflected and enters a follow-up flash tank device through a buffering cylin |
