Description
Technical field
The utility model is related to fume treatment technical fields, and in particular to a kind of flue gas desulphurization system.
Background technology
Currently, in Copper making industry, frequently with sodium method desulfurization technology, i.e., system is absorbed using alkaline matters such as sodium hydroxides
SO in sour tail gas2, sodium method desulfurization technology has the advantages such as desulfuration efficiency is high and by-product is disposable.However, sodium method desulfurization technology
It has the disadvantage that：First, desulfurizing agent is expensive, causes desulfurization operation of high cost；Second, in SO2The big feelings of content fluctuating range
Under condition, it is difficult to exhaust emissions be kept to stablize in reduced levels.Due to sodium method desulfurization technology above shortcomings, thus constrain
It is widely used.In addition, will produce a large amount of pH value in 9-10 when handling sulfuric acid production wastewater using lime stone breast-iron processes
Alkaline water, individually discharge need carry out pre-treatment.
Utility model content
The purpose of this utility model is to provide a kind of flue gas desulphurization system, can recycle alkaline recycle-water to absorb relieving haperacidity
SO in tail gas2, resource utilization is helped to improve, and reduce desulphurization cost.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of flue gas desulphurization system, including desulfurizing tower, the lower part and top of desulfurizing tower tower body are communicated with gas feeding pipe respectively
And outlet pipe, when handling sulfuric acid wastewater containing the alkaline recycle-water that generates by input duct enter gas feeding pipe and/orDesulfurizing tower。
The advantageous effect generated using above-mentioned technical proposal is：The utility model handles sulphur using lime stone breast-iron processes
The alkaline recycle-water that will produce when acid producing waste water absorbs the SO in flue gas during smelting2, to not only reduce the PH of waste water, but also carry
High fume treatment effect, ensures SO2Flue gas can be discharged under different operating modes with stably reaching standard, and can reduce flue gas desulfurization at
This, improves and is efficiently used to the cycle of resource.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
A kind of flue gas desulphurization system, as shown in Figure 1, including desulfurizing tower 10, the lower part of 10 tower body of desulfurizing tower and top difference
It is communicated with gas feeding pipe 11 and outlet pipe 12, the alkaline recycle-water generated when sulfuric acid wastewater containing is handled and is entered by input duct
Feed channel 11 and/orDesulfurizing tower10.When handling exhaust gas using above system, it is passed through after relieving haperacidity into desulfurizing tower 10 first
Smelting exhaust, while it being passed through the alkaline recycle-water generated when lime stone breast-iron processes handles sulfuric acid production wastewater, in this way, alkaline
Waste water can effectively absorb acid tail gas.This programme by waste water to being generated in acid manufacturing processes and exhaust gas carry out it is comprehensive,
It recycles, significantly reduces the desulphurization cost of flue gas.
More specific scheme is, the input duct includes the first input duct 21 and the second input duct 22, described the
One input duct 21 is connected to gas feeding pipe 11 and closes on the arrangement of desulfurizing tower 10；Second input duct 22 withDesulfurizing tower10
Connection and inlet are located at the top of mist eliminator 30.
Preferably, alkaline recycle-water is passed through there are two types of mode：
One is：As SO in tail gas2When content is relatively low, alkaline recycle-water is discharged into and can be inhaled by the first input duct 21
SO in ending gas2。
The second is：As SO in tail gas2When content fluctuation is larger, the first and second input ducts 21,22 can be opened simultaneously, such as
This can carry out exhaust gas mist eliminating recoil spray, quickly absorb the SO in flue gas2, ensure SO2Flue gas can be stablized under different operating modes
Qualified discharge.
Preferably, in the desulfurizing tower 10 along the direction of flue gas emission at least provided with a mist eliminator 30.
Preferably, set that there are three mist eliminators 30 in the desulfurizing tower 10 along the direction of flue gas emission.
