The invention discloses a combined falling film grid desulfurizing tower which comprises a tower body, wherein a smoke gas inlet and a falling film grid are arranged on one side of the upper part of the tower body, and a baffle plate demister is arranged on the other side of the upper part of the tower body; a purified smoke outlet is formed in the outer side of the baffle plate demister on the tower body; a slurry agitator is arranged below the falling film grid on the lower part of the tower body; a lime liquor supplementing inlet is formed in one side of the tower body on the lower part of the baffle plate demister; an oxidation and aeration system is arranged at the bottom of the tower body; and a dehydrated calcium plaster outlet is formed in the outer part of the oxidation and aeration system. The combined falling film grid desulfurizing tower disclosed by the invention has the beneficial effects that the tower body is simple in structure and compact in layout, the smoke can be effectively treated by the falling film grid and the baffle plate demister, the reaction of sulfur-containing liquor and lime liquor can be accelerated by the slurry agitator and the oxidation and aeration system, and gypsum can be periodically discharged from the dehydrated calcium plaster outlet.
Description
technical field [0001] The invention relates to the field of ambient air treatment, in particular to a combined falling film grid desulfurization tower. Background technique [0002] In the field of environmental air treatment, desulfurization towers are widely used as supporting equipment in coal-fired industrial boilers and flue gas desulfurization. The most commonly used spray absorption desulfurization towers mainly include spray empty towers, packed towers, double-circuit towers, and jet drum turrets. These desulfurization towers have complex structures, high tower ratios, large power consumption, and low desulfurization efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above technical defects and propose a combined falling film grid desulfurization tower with simple structure, low energy consumption and high desulfurization efficiency. [0004] The technical solution adopted by the present invention to achieve its...
