Safety online monitoring device for chlorine dioxide generator

The invention discloses a safety online monitoring device for a chlorine dioxide generator. The device comprises an emergency liquid storage tank, wherein the emergency liquid storage tank is communicated with a reactor of the chlorine dioxide generator through a pipe fitting, an electromagnetic valve is arranged on the pipe fitting, and the emergency liquid storage tank is used for storing alkaliliquor; the reactor is further provided with a pressure detecting device for detecting the gas pressure in the reactor, and transmitting the detected pressure information to the control system; and the control system controls the switching action of the electromagnetic valve according to the detection information. The safety online monitoring device for the chlorine dioxide generator absorbs thechlorine dioxide generated in the reactor and prevents the advanced reaction of raw materials, thereby achieving the purpose of ensuring equipment and personal safety, and preventing chlorine dioxidefrom overflowing to affect
