Abstract
Invenţia se referă la un procedeu de separare a poluanţilor gazoşi, cum ar fi dioxidul de sulf, din gazele tehnologice fierbinţi, cum ar fi gazul de fum.Esenţa invenţiei constă în aceea că gazele fierbinţi sunt trecute printr-un reactor de contact în care este introdus materialul absorbant în stare umedă, reactiv faţă de poluanţii gazoşi, transformând poluanţii gazoşi în praf, care se separă din gazul supus prelucrării în separator, partea majoră de praf fiind selectată din separator şi trecută printr-un amestecător, amestecată cu un absorbant proaspăt şi umezită, după care este recirculată în calitate de material absorbant în gazele supuse prelucrării.În calitate de absorbant proaspăt este utilizat varul calcinat, iar praful este menţinut în amestecător atâta timp şi recirculat de atâtea ori, încât timpul de aflare a varului calcinat în amestecător să fie suficient pentru ca varul calcinat să reacţioneze practic complet cu apa şi să formeze varul stins.Rezultatul tehnic al invenţiei constă în ieftinirea procesului datorită utilizării în calitate de absorbant a varului calcinat în locul varului stins.
