IMPROVEMENTS IN OR RELATING TO LIQUID SPRAYING |
摘要 |
<p>A method of treating a polluted gas e.g., desulphurising a sulphur dioxide-containing flue gas is carried out by spraying the flue gas with a slurry of e.g. calcium hydroxide, under spray drying conditions. The spray device comprises a rotating spray cup 18 comprising an extended surface 74 on which a film of slurry is formed. On leaving the surface 74 the slurry is immediately impacted with a high velocity stream of air supplied through an annular orifice 22. Arrangements for supplying the slurry to the rotating cup comprise a stationary distribution device 17a adapted to direct the slurry onto the surface 74 with a swirl component of motion. In an alternative embodiment the stationary distribution device is adapted to accelerate the slurry prior to a distributor cup which then directs it onto the extended surface of the spray cup in a direction generally opposed to the general direction of the slurry sprayed into the gas.</p> |
