Embodiment Construction
[0011] The secondary desulfurization and dust removal device of the present invention includes a casing and an alkali liquor circulation system. Its shell is a tank with an open top and bottom.
[0012] A supporting partition 4 is fixed on the lower part of the tank body, and a plurality of circular holes are arranged on the plate, and each hole is correspondingly fixed with a low-velocity Venturi tube 2 with a flow rate of 15-20 meters per second. On the top of the inner pipe, a diversion impact baffle plate 3 is fixed. The corresponding low-velocity Venturi tube position below the supporting partition is provided with a shower nozzle 1 communicated with the lye pipe, and this shower nozzle is a low-resistance nozzle that requires its resistance to drop within 2 meters of water column. The surface of the supporting partition is also coated with a coating 9 made of water glass and cast stone powder.
[0013] A mounting plate 5 is also fixed on the upper part of the tank body...
