Method for controlling aerosol generation in absorbing process by ammonia process of desulfurization

The invention discloses a method for controlling aerosol generation in absorbing process by an ammonia process of desulfurization. Sulfurdioxide is removed from flue gas with an absorption circulatingliquid containing ammonium sulfite in order to control generation of aerosol during absorption in the ammonia process of desulfurization. Efficient desulphurization and dust removal are realized by graded solution component control and reaction condition control, ammonia escape and generation of aerosol in the absorbing process are controlled during efficient desulfurization, initially cooled andpurified flue gas comes into contact with the absorption circulating liquid and a fine particle washing circulating liquid in sequence, the components of each stage of solution and reaction temperature are controlled, synergistical control of absorption, oxidization and concentration is realized, the absorbing efficiency in the absorbing process is ensured, ammonia escape and aerosol are controlled, meanwhile energy consumption is lowered, and long-term stable running of the device is realized.
