The utility model relates to the technical field of
flue gas treatment equipment, and discloses a
flue gas treatment device for a
brick kiln, which comprises a treatment tank and three supporting legs fixedly mounted at the bottom of the treatment tank, a gas inlet
pipe is arranged at the lower end of the outer wall surface of the treatment tank, and a water drainage
pipe is fixedly connected to the bottom of the treatment tank. An
exhaust pipe is fixedly connected to the top of the treatment tank, the air inlet
pipe, the
exhaust pipe and the drainage pipe are all communicated with the interior of the treatment tank, and two spraying pipes are fixedly mounted in the treatment tank. According to the
flue gas treatment device,
flue gas is introduced into the treatment tank through the gas inlet pipe, the
flue gas is firstly subjected to primary denitration by a mixed
solvent sprayed by the spraying pipe below, then in the rising process, the
flue gas subjected to primary denitration is guided into the baffle by the guide
ring block, and the flow speed of the flue gas is reduced by the baffle, so that the flue gas flows into the treatment tank when the flue gas rises through the interval between the baffle and the inner wall surface of the treatment tank; and the flue gas is sprayed and denitrated again by the spraying pipe above, so that the
nitrogen oxides in the flue gas are efficiently removed, and the
pollution of the
nitrogen oxides to the environment is reduced.
