Wet scrubber inlet awning with low pressure drop
First Claim
1. A device for deflecting a liquid slurry flow in a housing away from an inlet flue for conveying hot flue gas to the housing, the device having an upper surface and communicating with the housing at an inner wall of the housing, the device comprising:
- an inlet awning having a bottom portion horizontally extending into the housing from an upper surface of the inlet flue, and an inclined top portion connected to the bottom portion and an inner wall of the housing, the top portion extending upwardly at an incline from the bottom portion to the inner wall of the housing, the top portion having sufficient area to collect liquid slurry in excess of that required to achieve instant cooling and humidification of the hot flue gas, the top and bottom portions forming a tip at an area where the top portion is connected to the bottom portion; and
an extension outwardly extending from the tip of the inlet awning and slightly below the bottom portion of the inlet awning in order to deflect the liquid slurry flow away from the bottom portion of the inlet awning to keep the bottom portion dry.

Abstract
A device for deflecting a liquid slurry flow in a housing away from an inlet flue conveying hot flue gas to the housing, the device having an upper surface and communicating with the housing at an inner wall of the housing. An inlet awning having a bottom portion horizontally extends into the housing from an upper surface of the inlet flue. An inclined top portion is connected to the bottom portion and an inner wall of the housing, the top portion extending upwardly at an incline from the bottom portion to the inner wall of the housing, the top portion having sufficient area to collect liquid slurry in excess of that required to achieve instant cooling and humidification of the hot flue gas, the top and bottom portions forming a tip at an area where the top portion is connected to the bottom portion. An extension outwardly extends from the tip of the inlet awning and slightly below the bottom portion of the inlet awning in order to deflect the liquid slurry flow away from the bottom portion of the inlet awning to keep the bottom portion dry and thereby prevent build-up of slurry deposits at the inlet flue.

12. In combination with a wet scrubber module used in the desulfurization of hot flue gas, the wet scrubber module having a housing and an inlet flue for conveying hot flue gas to the housing and means for supplying a liquid slurry flow into the housing above the inlet flue, a device for deflecting the liquid slurry flow falling down within the housing away from the inlet flue to prevent deposition and build up of solids at the inlet, the device having an upper surface and communicating with the housing at an inner wall of the housing and further comprising:
-
an inlet awning having a bottom portion horizontally extending into the housing from an upper surface of the inlet flue, and an inclined top portion connected to the bottom portion and an inner wall of the housing, the top portion extending upwardly at an incline from the bottom portion to the inner wall of the housing, the top portion having sufficient area to collect liquid slurry in excess of that required to achieve instant cooling and humidification of the hot flue gas, the top and bottom portions forming a tip at an area where the top portion is connected to the bottom portion; and an extension outwardly extending from the tip of the inlet awning and slightly below the bottom portion of the inlet awning in order to deflect the liquid slurry flow away from the bottom portion of the inlet awning to keep the bottom portion dry.
