[0017] The liquid delivery pipeline 3 between the alkali tank and the alkali liquid tank adopts 316L corrosion-resistant stainless steel pipe.
[0018] The alkali tank truck 6 transfers the alkali to the alkali tank 1 by siphoning.
[0019] The liquid delivery pipeline 3 is provided with a pneumatic ball valve 5 .
[0020] The flow rate of the alkali solution input into the alkali solution tank 8 is adjusted by the pneumatic ball valve 5 .
[0021] The pneumatic ball valve 5 is automatically interlocked with the liquid level meter on the alkali liquid tank 8 to automatically adjust the flow rate.
[0022] The pneumatic ball valve 5 mentioned above adopts a lined ball valve.
[0023] After the caustic soda tank truck loads the caustic soda into the caustic soda tank through siphon, the caustic soda is input into the alkali liquid tank through the pneumatic ball valve, the lime slurry and the caustic soda are fully mixed with the stirring motor, and finally the alkali liquid pump is used to pump the mixed slurry into the desulfurization tower for use.
