(5) embodiment
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As shown in Figure 1, the acetate acid tail gas absorption plant include an absorbing cover 1, the top of absorbing cover 1 provided with a bottom with
The first pipeline 2 being connected inside absorbing cover, the top of the first pipeline 2 is connected with the import of a blower fan 3, and the outlet of blower fan 3 connects
Connect the import of one second pipeline 4, the outlet of the second pipeline 4 is connected with the bottom inlet of an absorption tower 5, in the absorption tower 5 on to
If lower uniform intervals are provided with dried layer packing layer, described filler layer is stainless steel cloth 6, the absorption tower 5 in the top of stainless steel cloth 6
Top is provided with several nozzles 7 along absorption tower radial direction, and each nozzle 7 is connected with the water pipe 8 located at the top of absorption tower 5,
The import of water pipe 8 passes the side wall of absorption tower 5 and connects water source；On absorption tower 5, top export connects one the 3rd pipeline 9, the 3rd pipe
Pond 10 of the rear end insertion on road 9 outside absorption tower 5 is set, and the import of one the 4th pipeline 11 is connected in the bottom of absorption tower 5,
The outlet of 4th pipeline 11 is connected with pond 10.
