Description
Technical field
The present invention relates to environment protection fields, and in particular to the system for removing glass furnace flue dust by acidolysis.
Background technique
When glass furnace normal operation, the smoke components generated are extremely complex, and soot dust granule partial size is microscale-nanoscale,
It is trapped with common method extremely difficult.
Summary of the invention
It is an object of that present invention to provide the systems for removing glass furnace flue dust by acidolysis, when solving glass furnace normal operation,
The smoke components that it is generated are extremely complex, and soot dust granule partial size is microscale-nanoscale, trapped with common method very difficult
Problem.Since particulate matter is alkali metal compound in flue gas, soluble compounds, which can be formed, with acid neutralization is removed
Go, therefore the present invention designs the system for removing glass furnace flue dust by acidolysis, by the method for acidolysis by glass furnace flue gas into
Row processing, is recycled, avoids environment by smoke pollution.
The present invention is achieved through the following technical solutions：
The system for removing glass furnace flue dust by acidolysis, the cleaner are arranged at flue outlet, and glass furnace will give birth to
Produce generate flue gas by flue be sent into cleaner in, the cleaner include complex acid equipment, with oxygen equipment, add alkali machine with
And gas wash tower, oxidizing tower, absorption tower, mother liquor pond and the cooling tower being sequentially communicated, the input terminal of the gas wash tower and going out for flue
Mouth connection, the complex acid equipment is connect with gas wash tower, and acid mist is sprayed into gas wash tower, described to connect with oxygen equipment and oxidizing tower
It connects, and sprays strong oxidizer into oxidizing tower, the adding machine is connect with absorption tower, and lye is added into absorption tower.
The flue gas that glass furnace generates enters gas wash tower by flue, while spraying acid mist dedusting from complex acid equipment to gas wash tower,
Alkali metal oxide in flue dust becomes soluble sulfate or hydrochloride or nitrate is dissolved in acid solution and is substantially completely removed.It removes
Flue gas after dirt enters in oxidizing tower, from oxygen equipment, to its oxidation reinforced dose, strong oxidizer and the nitric oxide in flue gas are complete
Full response generates nitrogen dioxide.Flue gas through aoxidizing enters absorption tower, and excessive soda ash liquid or caustic lye of soda are sprayed into absorption tower,
So that it is fully absorbed the nitrogen dioxide of generation, generates sodium nitrate and sodium nitrite mixed liquor.When reaction terminates, which is taken out
Enter in mother liquor pond, enters back into cooling tower and carry out low-temperature evaporation concentration, finally obtain the mixture of sodium nitrite and sodium nitrate.This is mixed
Object is closed, glass factory is recyclable to be used again.
The present invention is handled glass furnace flue gas by the method for acidolysis, is recycled, avoids environment by cigarette
Gas pollution.
Compared with prior art, the present invention having the following advantages and benefits：
The system that the present invention removes glass furnace flue dust by acidolysis, will be at glass furnace flue gas by the method for acidolysis
Reason, is recycled, avoids environment by smoke pollution.
