Description
technical field:
The utility model relates to a kind of acid hydrolysis tail gas venturi spray absorber, belongs to Chemical Manufacture tail gas disposal technique field.
background technology:
In sulfuric acid method titanium pigment is produced, the process of acid hydrolysis tail gas mostly adopts flue to spray, after promote in the industry Wuhan circumference acid hydrolysis tail gas processing mode, titanium white company also introduces this technology, but due to me, to take charge of the acidolysis main reaction time short in reality is produced, acid hydrolysis tail gas is released in the short period of time in a large number, has the thing of discharge beyond standards to occur when acid hydrolysis tail gas is after flue spray, Water spray absorb.
utility model content:
The purpose of this utility model provides a kind of acid hydrolysis tail gas venturi spray absorber for above-mentioned Problems existing, carries out structural transformation to existing Venturi, can preferably to the SO in acid hydrolysis tail gas
2spray-absorption, guarantees acid hydrolysis tail gas qualified discharge.
Above-mentioned object is realized by following technical scheme:
Acid hydrolysis tail gas venturi spray absorber, comprise the Venturi tube be connected with acid hydrolysis tail gas air inlet pipe, the inlet end of described Venturi tube is connected with described acid hydrolysis tail gas air inlet pipe, the diffusion end of described Venturi tube is connected with collector tube, is provided with Water spray head and alkali lye spray head inside described Venturi tube.
Described acid hydrolysis tail gas venturi spray absorber, described Water spray head is annular, is arranged on the throat of described Venturi tube.
Described acid hydrolysis tail gas venturi spray absorber, described alkali lye spray head is positioned at the top of described Water spray head.
Described acid hydrolysis tail gas venturi spray absorber, the bottom of described collector tube is provided with leakage fluid dram, and the top of described collector tube is provided with exhaust outlet.
Described acid hydrolysis tail gas venturi spray absorber, described acid hydrolysis tail gas air inlet pipe is provided with 4 Venturi tubes.
Beneficial effect:
1. the utility model adopts Venturi tube, the pressure increase of acid hydrolysis tail gas when acid hydrolysis tail gas enters the throat of Venturi tube from the inlet end of Venturi tube, at this time adopt and add alkali spray on the basis of Water spray, tail gas is reacted, absorbs, guarantee that exhaust emissions is up to standard.
2. Water spray head of the present utility model is designed to annular, and is just in time in the throat of Venturi tube, can guarantee to absorb when acid hydrolysis tail gas pressure is maximum, and assimilation effect is best.
3. alkali lye spray head of the present utility model is arranged on the top of Water spray head, first carries out neutralization reaction to acid hydrolysis tail gas, and react incomplete and absorb through water, treatment effect is better.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure 1, acid hydrolysis tail gas air inlet pipe; 2, Venturi tube; 3, collector tube; 4, Water spray head; 5, alkali lye spray head; 6, leakage fluid dram; 7, exhaust outlet.
detailed description of the invention:
