式集塵装置。[Scope of Claim for Utility Model Registration] A water spray device that cools blast furnace exhaust gas in a dust catcher, which is introduced from the blast furnace via piping, by spraying atomized water; The output of the dry dust collector introduced through the dust catcher and the upstream thermometer that measures the blast furnace exhaust gas temperature on the upstream side of the dust catcher is input through the dead time circuit, and the spray start temperature set value is set. Equipped with a spray start alarm setting device,
When the input of the spray start alarm setting device reaches the spray start set value, the water spray device is activated to lower the temperature of the blast furnace exhaust gas guided to the dry dust collector. In the apparatus, the dead time circuit is connected in series between the output side of the upstream thermometer and the input side of the spray start alarm setting device, and the dead time circuit adjusts the temperature of the blast furnace exhaust gas inlet side of the dry dust collector. calculate the estimated value,
A dry type dust collector for blast furnace exhaust gas, characterized in that a first-order delay circuit is provided for inputting this to the spray start alarm setting device.
