Embodiment：
As shown in figure 1, a kind of processing unit for aluminum trichloride (anhydrous) production tail gas, includes the buffering being sequentially connected
Tank 1, water scrubber 2, reaction tower 4, alkalization tower 6, air-introduced machine 8, evacuated tube 10, the surge tank 1 are provided with production inlet exhaust gas A,
The water scrubber 2 is provided with running water inlet B, and the water scrubber 2, reaction tower 4, alkalization tower 6 are equipped with discharging opening, and discharging opening
Two branch roads are provided with by pipeline, the wherein branch road in the water scrubber 2, reaction tower 4, alkalization tower 6 is connected to three
Aluminium chloride waste water basin 3, sodium hypochlorite basin 5, reaction tower 4, another branch road connect with its own backflow respectively, the alkalization
Tower 6 is also associated with liquid caustic soda basin 7, and the air-introduced machine 8 is connected with frequency-variable controller 9.
Specifically, installation material-blocking plate 11 in the surge tank 1, while manhole discharging opening is provided with, it is easy to alchlor dust
Cooling, sedimentation, discharging.
Specifically, the configuration of air-introduced machine 8 is provided with frequency-variable controller 9, it is easy to, according to production requirement, adjust in process of production
Save air inducing fan delivery.
Operation principle of the present utility model is：Caused tail gas passes through inlet exhaust gas to aluminum trichloride (anhydrous) in process of production
A enters in surge tank 1, and in the presence of material-blocking plate 11, a small amount of alchlor dust settling gets off in tail gas, reaches a certain amount of
When, manhole discharging opening is opened, is discharged by manhole discharging opening, and the alchlor dust not settled down enters water scrubber 2
In, waste water enters aluminium trichloride waste water tank 3 after being washed by water scrubber 2, unabsorbed gases into reaction tower 4 with liquid caustic soda
React, after circular response generates sodium hypochlorite, be discharged into after analysis is qualified in sodium hypochlorite basin 5, do not absorbed, be anti-
The gas answered enters in alkalization tower 6, continues that neutralization reaction occurs with liquid caustic soda, make it is acid it is discarded it is completely processed after, through air-introduced machine 8
Evacuated tube 10 is introduced, realizes high-altitude qualified discharge, circulating absorption solution can be used for reaction tower 4 to produce sodium hypochlorite in the tower 6 that alkalizes, and
