Brief description of the drawings
Fig. 1 is the principle schematic of the present invention.
Embodiment
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the accompanying drawings with embodiment to this
Invention is described in further detail.
As shown in figure 1, the automatic control system of waste gas tower exhaust-gas treatment, including, exhaust producing device 1, produced with waste gas
The floss hole 2 that device 1 is connected, in addition to collect the waste gas tower 3 of waste gas, at least water inlet pipe 4, two sprays connected with water inlet pipe
Drench pump 5, the spray header 6 connected with spray pump, at least two sparge pipes on spray header；It is at least one to be located at waste gas
Exhaust gas concentration sensor 7 in tower or floss hole, the concentration alarm 8 being connected with exhaust gas concentration sensor 7；The floss hole
2 are located at waste gas top of tower, and sparge pipe connects with waste gas tower 3, and the spray pump 5 is connected with concentration alarm 8；In floss hole
Upper end open at be additionally provided with demister 10.
Demister 10 can use commercially available stacked demisting plate, mainly remove water smoke, reduce ejection and the row of reduction of water
The fog on mouthful visual angle is put, all gas pass through demister.
Sparge pipe quantity can be set according to the size of waste gas tower 3, it is ensured that spray thoroughly purifies waste gas without dead angle；Equally
Ground, exhaust gas concentration sensor 7 can be also positioned in waste gas tower 3 or in floss hole 2 according to actual conditions.The discharge of waste gas tower 3
Water is handled into sewage disposal system.
In order to preferably be purified to caused waste gas in production process, pretreatment unit 9 is still further comprised, it is described
Pretreatment unit 9 is connected with exhaust producing device 1 and waste gas tower 3 respectively.Pretreatment unit 9 namely primary exhaust tower, it is primary
