Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.
Example (b):
as shown in fig. 1-3, the present invention provides a high-efficiency tandem washing absorption tower 1, which comprises a plurality of absorption towers 1 connected in series in sequence, preferably two absorption towers 1 connected in series. The absorption tower is characterized in that two layers of packing layers 2 are arranged in parallel in the absorption tower 1, the bottom of the absorption tower 1 is communicated with a reflux pool 3, an air inlet 4 is arranged on the side surface of the absorption tower 1 between the reflux pool 3 and the packing layer 2, an air outlet 5 is formed in the top of the absorption tower 1, and the air outlet 5 of the previous absorption tower 1 in the two adjacent absorption towers 1 is connected to the air inlet 4 of the next absorption tower 1 through a pipeline. When in use, the waste gas moves upwards from the bottom of the absorption tower 1, respectively passes through the water-containing packing layers 2 at two sides and is discharged from the top; because of the utility model discloses in have two-layer packing layer 2 that sets up side by side, can carry out more abundant purification to waste gas, improve treatment effect, simultaneously the utility model discloses be equipped with a plurality of scrubbing tower and establish ties to purify waste gas many times, the improvement purifying effect that can very big degree makes waste gas after the purification reach the standard of direct emission to the air.
