[0032] The following is a detailed description of the process and device of the present invention with reference to the flue gas discharged by a coal-fired boiler unit in conjunction with the accompanying drawings:
[0033] As shown in Figure 1, the wet ammonia flue gas desulfurization device with double-side opposed air intake has a desulfurization tower 3. The bottom of the desulfurization tower 3 is provided with a slurry outlet 8 for desulfurization by-products, and the top of the desulfurization tower 3 is provided The clean flue gas outlet 4 and the desulfurization tower 3 are successively provided with a bottom desulfurizing agent slurry pool area, a lower flue gas input area, a middle flue gas diversion and desulfurizing agent spraying area, and an upper flue gas defogging area from bottom to top. An ammonia water supply device 10 and an air feed device 9 are connected to the bottom desulfurization agent slurry pool area of the desulfurization tower 3. Two opposite sides...
