Description
Technical field
The utility model belongs to phosphorus production equipment technical field, and in particular to generates during a kind of pair of phosphorus production
The device of yellow phosphoric tail gas progress purified treatment.
Background technique
Yellow phosphorus is important the basic material of basic chemical raw materials and phosphorous chemical industry.Enterprise is most both at home and abroad at present
All use producing yellow Phosphorus by electric oven.As soon as every production ton yellow phosphorus in its production process generates about 2700Nm simultaneously3Containing carbon monoxide
89~91% or more yellow phosphoric tail gas.
Yellow phosphoric tail gas mainly contains CO, and there are also impurity such as dust, phosphorus, sulphur, arsenic, fluorine, calorific value is up to~10000KJ/Nm3, it is
A kind of good industrial chemicals and fuel.But current China's phosphorus production Enterprise Integrated utilizes horizontal lower, most of Yellow Phosphorous Plant
The utilization rate of tail gas is only 30% or so, and a large amount of direct burning and exhausting of yellow phosphoric tail gas furnace gas causes greatly to pollute to environment.
The Ministry of Industry and Information Technology's bulletin in 2008: implement " Yellow Phosphorus Industry entry criteria " from January 1st, 2009, it is desirable that phosphorus furnace exhaust gas
It in line must not burn, it is necessary to realize that energy or resource utilization utilize, newly-built yellow phosphorus unit tail gas comprehensive utilization ratio must reach
To 90% or more.But the impurity such as dust, phosphorus as contained in yellow phosphoric tail gas, sulphur, arsenic, fluorine, after being both needed to purification removing partial impurities
It can utilize.
Currently, the purifying exhausting gas of yellow phosphorus device that most of phosphorus production enterprise uses, clean-up effect is not significant, largely effects on
Purification efficiency can be greatly improved in the comprehensive utilization of yellow phosphoric tail gas, the exhaust gas cleaner of the utility model, reduce purification life
Produce cost, it is ensured that the decontamination index of cleaning of off-gas.
Utility model content
To solve the above problems, the utility model provides a kind of purifying exhausting gas of yellow phosphorus device.
The utility model is realized using following technical scheme: a kind of purifying exhausting gas of yellow phosphorus device, including yellow phosphoric tail gas into
Mouthful pipeline and the scrubbing tower connected with tangential direction are additionally provided with sprayer-washer I on the yellow phosphoric tail gas inlet pipeline, described
The middle part of scrubbing tower is equipped with ring baffle, top is equipped with foam removal packing layer, is equipped with sprayer-washer II above foam removal packing layer.
The yellow phosphoric tail gas inlet pipeline is L-type pipe bucket, and the top of L-type pipe bucket is inlet exhaust gas, and the tail end of L-type pipe bucket is
Gas-liquid mixed outlet, gas-liquid mixed outlet enter scrubbing tower using tangential swirl.
The wash tower bottoms are equipped with outlet of sewer.
When installing and using, yellow phosphoric tail gas flows into the utility model from yellow phosphoric tail gas inlet pipeline, through yellow phosphoric tail gas import
After I spray washing of sprayer-washer in pipeline, along a tangential direction from scrubbing tower, from bottom to top, yellow phosphoric tail gas is removed as far as possible
The solid particle polluter and drop of middle carrying reach gas-solid-liquid separation, and setting ring baffle prevents gas from being formed in the middle part of scrubbing tower
Vortex, is uniformly distributed yellow phosphoric tail gas in scrubbing tower.Cleaning solution is entered by the top of scrubbing tower by sprayer-washer II, with
Yellow phosphoric tail gas continues through the gap of the foam removal packing layer on scrubbing tower top in adverse current, and in filler surface, gas-liquid two-phase is close
Contact carries out mass transfer and achievees the purpose that purification to remove the impurity such as the dust in yellow phosphoric tail gas, phosphorus, arsenic, fluorine, sulphur, final yellow
Phosphorus tail gas flows out at the top of scrubbing tower.
In the present invention, the setting of yellow phosphoric tail gas inlet pipeline is in scrubbing tower lower part and along tangential direction air inlet,
Sprayer-washer I is arranged in yellow phosphoric tail gas inlet pipeline, can carry out spray washing to yellow phosphoric tail gas, remove most of impurity.It is washing
Tower top setting foam removal packing layer is washed, sprayer-washer II is set at the top of scrubbing tower, then carries out secondary washing, to improve Huang
The clean-up effect of phosphorus tail gas clean-up.
The advantages of the utility model has and effect: in the present invention, processed by purifying exhausting gas of yellow phosphorus device
Yellow phosphoric tail gas, can be directly used as fuel and as industrial chemicals produce chemical products.The utility model simple process, user
Just, the purification of the impurity such as dust, phosphorus, arsenic, fluorine, sulphur in phosphorus production in tail gas can be removed partial impurities, as various combustions
Material and industrial chemicals.
