The invention discloses a novel lower-pressure-drop distribution plate applicable to a multilayered
bed. The novel lower-pressure-drop distribution plate comprises
sieve holes (1), an overflowing weir (2), a material dropping hole (3), large-hole nozzles (4) and matched air caps (5) thereof, a
flange edge (6) and
flange holes (7), wherein the distribution plate is an incomplete round plate and a notch is the material dropping hole (3); the overflowing weir (2) vertical to the distribution plate is arranged at the edge of the notch; the large-hole nozzles (4) are uniformly distributed on the plate and are matched with the air caps (5); air cap small holes (18) are uniformly distributed in the air caps (5); the
sieve holes (1) are formed among the large-hole nozzles at intervals; and the edge of the distribution plate is the
flange edge (6) and is provided with the flange holes (7). With the adoption of the novel lower-pressure-drop distribution plate, the pressure drop of the multilayered
bed can be effectively reduced, and gas-liquid flowing is disordered; the contact area between
flue gas and a
solid purifying agent is large, and a gas flowing path is long, so that enough
gas retention time is guaranteed; and the
flue gas is in sufficient reaction with the
solid purifying agent, and the novel lower-pressure-drop distribution plate has operational flexibility.
