Small and desulfurizer performance differs, 600MW units about per hour 10~30t/h, 1000MW unit about per hour 20~
50t/h.The waste liquid that wet desulfurization system generates needs consumption large quantities of lime stone to be disposed, breaks simultaneously after returning to desulphurization system
Bad water balance, these acid solutions can be completely used for the weak male form resin of Direct Regeneration and the processing of recirculated water acid adding after collecting, through overrich
It can be used for regenerating strong male form resin after contracting.The recycling of this part waste liquid is conducive to the consumption to save material, together
When be conducive to desulphurization system water balance.
