Description

Technical field:

[0001] The utility model relates to the technical field of flue gas treatment, in particular to an environmentally friendly lime kiln flue gas low-temperature denitrification device. Background technology:

[0002] During the lime burning process, a large amount of waste gas and dust will be generated. The flue gas temperature coming out of the lime kiln body is ≥470℃. The flue gas contains particulate matter, SO2, NOX, etc. When NOX and hydrocarbons coexist in the air, a photochemical reaction occurs under the irradiation of sunlight ultraviolet rays, producing a photochemical smog, which is a toxic secondary pollutant.

[0003] For example, a lime kiln flue gas low-temperature denitration device with the authorization announcement number "CN219964515U" generates N2 and H2O by reacting NOx in the flue gas with the injected ammonia under the action of the low-temperature SCR catalyst, thereby achieving the removal of NOx in the flue gas and reducing the escape of NH3. The flue gas after denitration is sent to the chimney through the fan for discharge, reducing pollution emissions and protecting the ecological environment. However, when the device treats the exhaust gas, the smoke dust is treated by a cyclone separator and a bag filter, but the device is not convenient for rapid treatment of the collected smoke dust, and it will also cause the device to be inconvenient for rapid replacement of the filtering equipment. When the smoke dust filtration reaches saturation, the exhaust gas cannot be further treated, which affects the treatment effect of the device. At the same time, when the device is performing denitration treatment, it is not convenient for the exhaust gas and the treatment agent to be treated for a long time, which further leads to poor treatment effect of the device. When the poorly treated exhaust gas is discharged, it will cause environmental pollution, resulting in the device being not environmentally friendly. Utility model content:
