H-shaped flue gas dust removal desulfurization tower and flue gas desulfurization method

The present invention discloses an H-shaped flue gas dust removal desulfurization reactor and a flue gas desulfurization method. The desulfurization tower of the present invention comprises a pre-treatment unit and a deep treatment unit, wherein the two units form an H-shaped double-tower structure, the pre-treatment unit comprises a flue gas inlet, a water membrane assembly, a first-stage spraying system, a common jujube seed-shaped regular packing assembly, a turbulent scrubber and a first-stage liquid holding tank from top to bottom, the deep treatment unit comprises a second-stage liquid holding tank, a packing assembly, a demister and a purified flue gas outlet from bottom to top, and the pre-treatment unit and the deep treatment unit are communicated through the flue gas channel on the middle portion. According to the desulfurization tower of the present invention, the common jujube seed-shaped regular packing assembly and the high level potential energy of the turbulent scrubber absorbing liquid can be utilized to concurrently pre-treat the flue gas, and the desulfurization tower has advantages of high contaminant removal rate, low energy consumption and the like, and is especially for the dust removal desulfurization process of high dust content flue gas.
