The invention provides a gasification cooling flue in front of an evaporative cooler, which comprises an air inlet flue gas pipe connected in sequence, an evaporative cooler cylinder body and an air outlet flue gas pipe, and the air inlet flue gas pipe is formed by a first air inlet pipe , the second air intake pipe, the first close-packed pipe, the second close-packed pipe and the third close-packed pipe; flow device, and the second flow guide device arranged at the entrance of the third close-packed pipe; the first flow guide device and the second flow guide device both include a plurality of flow guide plates arranged at intervals; the flow guide plate can wrap around its own geometry Axis rotation. In the present invention, a guide device is arranged inside the gasification cooling flue in front of the evaporative cooler, which improves the uneven distribution of the smoke flow field, eliminates the vortex and backflow of the smoke inside the evaporative cooler, and effectively avoids The fouling problem caused by the backflow of flue gas is eliminated.
Description
technical field [0001] The invention belongs to the field of converter dry dust removal system, and in particular relates to a gasification cooling flue in front of an evaporative cooler and a manufacturing method. Background technique [0002] Converter gas dry electrostatic precipitator can greatly reduce water consumption, efficiently recover steam and gas, and is an advanced technology for iron and steel enterprises to realize converter negative energy steelmaking. The converter gas enters the evaporative cooler after being cooled for the first time through the vaporization cooling flue, and atomized water is sprayed through the double-medium atomizing nozzle to cool down, temper and rough dust the flue gas, so that the temperature of the converter flue gas is changed from 800 ℃~1000℃ is reduced to the range of 150℃~200℃, meanwhile, the humidity, specific resistance and dust viscosity of the converter flue gas can meet the requirements of the dry electrostatic precipitat...
