Example Embodiment
[0034] Example one:
[0035] Follow the steps below to treat the above flue gas:
[0036] S1. The flue gas from the flue gas main pipe enters the flue gas pipe under the action of the induced draft fan 3. The flue gas flow rate is 3500m 3 / h. At the same time, the prepared alkaline spray water is pumped by the circulating cooling pump 8 to spray and cool the high-temperature flue gas in the flue gas pipeline, so as to cool the flue gas and complete the process of preliminary desulfurization and dust collection at the same time. It is measured that the flue gas temperature drops to 58°C before entering the desulfurization tower.
[0037] S2. After the flue gas is desuperheated, it enters the desulfurization tower, and the desulfurization tower is provided with an adsorption catalyst solid bed 103, and the adsorption catalyst filled with the adsorption catalyst solid bed 103 is based on pseudo-boehmite as the framework, aluminum magnesium silicon After roasting with acid salt as auxi...
Example Embodiment
[0043] Embodiment two:
[0044] Follow the steps below to treat the above flue gas:
[0045] S1. The flue gas from the flue gas main pipe enters the flue gas duct under the action of the induced draft fan 3. The flue gas flow rate is 8600m 3 / h. At the same time, the prepared alkaline spray water is pumped by the circulating cooling pump 8 to spray and cool the high-temperature flue gas in the flue gas pipeline, so as to cool the flue gas and complete the process of preliminary desulfurization and dust collection at the same time. It is measured that the flue gas temperature drops to 62°C before entering the desulfurization tower.
[0046] S2. After the flue gas is desuperheated, it enters the desulfurization tower, and the desulfurization tower is provided with an adsorption catalyst solid bed 103. The adsorption catalyst filled with the adsorption catalyst solid bed 103 is based on pseudo-boehmite as the framework, aluminum magnesium silicon After roasting with acid salt as auxil...
Example Embodiment
[0052] Example three:
[0053] Follow the steps below to treat the above flue gas:
[0054] S1. The flue gas from the flue gas main pipe enters the flue gas duct under the action of the induced draft fan 3, and the flue gas flow rate is 11200m 3 / h. At the same time, the prepared alkaline spray water is pumped by the circulating cooling pump 8 to spray and cool the high-temperature flue gas in the flue gas pipeline, so as to cool the flue gas and complete the process of preliminary desulfurization and dust collection at the same time. It is measured that the flue gas temperature drops to 57°C before entering the desulfurization tower.
[0055] S2. After the flue gas is desuperheated, it enters the desulfurization tower, and the desulfurization tower is provided with an adsorption catalyst solid bed 103. The adsorption catalyst filled with the adsorption catalyst solid bed 103 is based on pseudo-boehmite as the framework, aluminum magnesium silicon After roasting with acid salt as a...
