Abstract
The invention relates to a boiler smoke cyclone separation recycling device and a smoke recycling method thereof. According to the technical scheme, the device is characterized in that a flue of a boiler with a return feeder is provided with an electric bag dust remover, two parallel cyclone separators are arranged between the flue of the boiler and the electric bag dust remover, first discharging valves are arranged at the discharging ends of the cyclone separators, a pipeline below the first discharging valves is communicated with a first bin pump, a second discharging valve and a second bin pump are arranged at the discharging end of the electric bag dust remover, a discharging port pipeline of the first bin pump and a discharging port pipeline of the second bin pump are connected in series to be communicated with a dust pipeline, the two ends of the dust pipeline are communicated with the return feeder and a dust field of the boiler respectively, the discharging port pipeline of the first bin pump is connected to the end, close to the return feeder of the boiler, of the dust pipeline, and the discharging port pipeline of the second bin pump is connected to the end, away from the return feeder of the boiler, of the dust pipeline; and the first bin pump and the second bin pump are connected to a compressed air pipe so that controllable compressed air can be introduced; and a control valve a and a control valve b are arranged at the two ends of a joint of the dust pipeline and the discharging port pipeline of the first bin pump.
Description
technical field [0001] The invention relates to a cyclone separation and recycling device for boiler smoke and dust and a method for recycling and using the smoke and dust, belonging to environmental protection equipment. Background technique [0002] The circulating fluidized bed boiler flue gas treatment device only equipped with electric bag dust removal, due to the high concentration of dust in the flue gas, the dust removal process will cause a large load on the electric bag dust collector, and the failure rate is high. Moreover, the dust concentration in the discharged flue gas is also high, which cannot meet the environmental protection production requirements. [0003] The flue gas concentration of circulating fluidized bed boilers is high, and the carbon content in the exhausted flue gas is high, indicating that the fuel combustion rate is low, and the low exhaust gas temperature requires more fuel, high energy consumption, and the dust is only collected. Other pro...
