The desulfurizer NaHCO3 is injected into the flue gas pipeline to react with the flue gas at the temperature of 270-290 DEG C, after activation of thermal decomposition in high temperature waste gas, sodium based powder was fully in contact with SO2 in waste gas, chemical reaction took place, and SO2 absorption and purification were carried out.
And the sodium sulfate generated by the dry-process desulfurization is discharged into a desulfurization ash bin through a dust collector. After the desulfurization, the waste gas enters the denitration and dust removal integrated device, and the flue gas after the dust removal is fully mixed with a reducing agent (ammonia gas) which is added with the ammonia spraying device through a cloth bag to enter the denitration catalyst layer, and a reduction reaction is carried out under the action of the catalyst to remove the NOX.
Shanxi Yongxin 600,000 tons, 1.2 million tons of coking project through the SDS desulfurization device, the SO2 emission concentration reaches the standard of ultra-low emission of the coking industry, and it is the successful cooperation of the two units of Shandong Mingsheng and Shanxi Yongxin again!
