[0046] As mentioned above, in the pH value control process of the above-mentioned desulfurization system, there may be a desulfurization dead zone, which may cause a series of adverse effects. In order to avoid adverse consequences caused by the appearance of a desulfurization blind zone, the embodiment of the present application provides a method for detecting a blind zone during the pH value control process of a desulfurization system. see image 3 , which shows the flow of the blind spot detection method according to the first embodiment of the present application. This first embodiment includes:
[0047] Step S301: Detect the pH value of the limestone slurry in the absorption tower and the slurry supply flow rate entering the absorption tower at the first moment, and record as the first pH value and the first slurry supply flow rate;
