1. , a kind of method of regulating internal flow field of circulating fluidized bed desulfurization tower is characterized in that this circulating fluidized bed desulfurization tower (1) is made up of smoke inlet pipe (2), deflector (3), venturi tube bank (4), recirculating fluidized bed bed body (5), desulfurizing agent and feed back inlet (6), atomized water spout (7), exhanst gas outlet (8);

  • The middle part of desulfurizing tower (1) is a recirculating fluidized bed bed body (5), downside at recirculating fluidized bed bed body (5) is respectively equipped with desulfurizing agent and feed back inlet (6), atomized water spout (7), the bottom of recirculating fluidized bed bed body (5) is connected with venturi tube bank (4), the end opening of venturi tube bank (4) is connected with smoke inlet pipe (2), the deflector (3) of regulating air-flow is arranged in smoke inlet pipe (2), and exhanst gas outlet (8) is located at the top of desulfurizing tower (1);

    At the boiler smoke circulating fluidized bed desulfurization tower that comprises a plurality of Venturi tube structures,, make recirculating fluidized bed bed body flow field reach even, symmetrical by changing the venturi diameter of desulfurizing tower bottom venturi tube bank in the zones of different position.
