<p>The depurator 4 is arranged at the fume release chimney exit, after a known solid particle release mechanism 2, and has the purpose of removing sulphurous anhydride from the combustion gases. The fumes, already free from solid particles, enter an expansion chamber provided with atomizers 5 which eject under pressure a liquid wherein the sulphurous anhydride is fixed, the liquid being aspired from a container 7 through an electropump group 6. Under gravity, the liquid falls from the expansion chamber in order to be re-used. Inside the container 7 a stirrer 10 homogenizes the mixture. After neutralization the liquid is drained to the sewer through a drainage 11. The electropump group 6 may function automatically with a boiler burner. <IMAGE></p> |
