Flue gas denitrification and purification device for industrial furnace

The flue gas denitrification and purification device comprises a base, an exhaust fan is fixedly installed on the left side of the top of the base, the left side of the exhaust fan is communicated with a gas collecting pipe, the right side of the exhaust fan is communicated with a first air supply pipe, and a dissolving device is arranged on the top of the base and located on the right side of theexhaust fan. A water pump is fixedly installed at the bottom of the right side of the dissolving device and located at the top of the base. According to the utility model, flue gas in the kiln is sucked into the dissolving box through the cooperation of the gas collecting pipe, the exhaust fan and the first air supply pipe, so that nitrides in the flue gas are dissolved in water, the subsequent neutralization is facilitated, and a solution in the dissolving box cannot flow out through the arrangement of the water stop valve; through cooperation of a water stop valve, a water pump and a waterconveying pipe, water in t
