Embodiment Construction
[0025] The structural drawings and embodiments of a turbulent ball turbocharged desulfurization and dedusting tower proposed by the present invention are described in detail as follows:
[0026] The overall structure of an embodiment of the present invention is as follows figure 2 As shown, it includes: a spray tower body 20, a flue gas inlet 201, a flue gas outlet 202, and a slurry discharge port 203 are arranged on the lower side wall, top and bottom of the tower body, and a passage and tower The slurry discharge pump 261 connected to the bottom slurry discharge port (the slurry discharged by the slurry discharge pump is sent to the cyclone for solid-liquid separation and recycling, this part does not belong to the content of the present invention), which is set at the bottom of the tower and is composed of a reaction tank and a recycler. The aeration pipe 24 in the liquid storage area formed by the circulation tank, the Roots blower 22 that links to each other with the aer...
