Abstract
The invention belongs to the technical field of sulfur-containing waste gas purification, and discloses a method taking a boiler as a treatment device for treating low-concentration sulfur-containing waste gas such as sulfureted hydrogen, carbon disulfide and the like. Compared with the traditional treatment method, the invention has the advantages of simple process, low cost of investment and operation, large gas treatment amount and obvious removal effect, and is particularly suitable for purification treatment of sulfur-containing waste gas of viscose production enterprises.
Description
Technical field
The present invention relates to a kind of emission-control equipment, particularly relate to a kind of device that utilizes the boiler combustion sulphur-containing exhaust gas.
Technical background
Viscose staple fibre manufacturing enterprise produces a large amount of waste gas in process of production, wherein contain pernicious gases such as hydrogen sulfide, carbon disulfide, the higher existing processing method preferably of part of concentration in these waste gas, the part that concentration is lower is bigger because of its total amount, the intractability height, never good at present treating method.The low concentration gas total amount that general viscose staple fibre production line produces is mostly per hour below 10 ten thousand steres, the big production of serialization like this, and every day, the exhausted air quantity of generation was very big.For this part waste gas, the method that domestic production enterprise takes is, directly utilizes exhaust tower to carry out high altitude discharge, dilution, like this surrounding environment caused very adverse influence.
Summary of the invention
The present invention aims to provide a kind of investment and operating cost is low, it is large-minded to handle, remove hydrogen sulfide, carbon disulfide outstanding effect emission-control equipment.
The low concentration gas amount that viscose staple fibre manufacturing enterprise is produced all is lower than this enterprise and provides the required intake of boiler combustion for oneself, and the oxygen content no significant difference in oxygen content and the atmosphere in the waste gas, and it is required to satisfy the boiler normal combustion.
Key of the present invention is that boiler itself is as waste gas treatment equipment, be equipped with exhaust-carrying device with the waste gas that produced in the viscose staple fibre production process with after the boiler air intake mixes mutually, send into boiler through boiler fan, after the burner hearth internal combustion, pernicious gases such as the hydrogen sulfide in the waste gas, carbon disulfide are converted into sulfur dioxide, flue gas enters flue gas desulfur device through superheater, economizer, pocket preheater, removes sulfur dioxide after send into chimney by air-introduced machine, enters atmosphere.
Contain hydrogen sulfide gas in the waste gas because of the present invention's processing, its corrosivity is stronger, so carry the pipeline of waste gas should adopt fiberglass, plastic or other material.Boiler cold air duct inner surface also should be done anti-hydrogen sulfide corrosion and handle.The boiler air preheater tubulation is preferably selected the steel of sulfur corrosion resistant for use.
Describe the present invention below in conjunction with accompanying drawing.
Accompanying drawing is a device schematic diagram of the present invention.
1. burner hearths among the figure, 2. superheater, 3. economizer, 4. air preheater, 5. boiler cold air duct, 6. valve, 7. waste gas air channel, 8. pressure fan, 9. flue, 10. flue gas desulfur device, 11. air-introduced machines, 12. chimneys.
During the device operation, sulphur-containing exhaust gas after collecting, is sent to boiler shop by waste gas air channel 7 at the viscose staple fibre workshop, enters burner hearth burning 1 after boiler fan 8 is sent into air preheater 4 preheatings; Before boiler fan 8, can replenish the part air by boiler cold air duct 5, make the total blast volume that enters boiler satisfy the required air capacity of boiler combustion, additional air capacity can be regulated by valve 6.
Sulphur-containing exhaust gas in burner hearth 1 through the burning after, hydrogen sulfide, carbon disulfide are converted into sulfur dioxide in the waste gas, mix mutually with boiler smoke, through entering boiler flue 9 behind superheater 2, economizer 3, the air preheater 4, send into flue gas desulfur device 10, remove sulfur in smoke.Flue gas after the desulfurization is sent into chimney 12 through air-introduced machine 11 and is entered atmosphere.
Contain hydrogen sulfide gas in the waste gas that the Yin Ben device is handled, has stronger corrosivity, so fiberglass, PVC plastic production should be adopted in waste gas air channel 7, valve 6 should adopt the aluminum alloy materials of hydrogen sulfide corrosion resistant to make, boiler cold air duct 5 inner surfaces also should be done corresponding preservative treatment, and boiler air preheater 4 tubulations preferably select for use the steel of sulfur corrosion resistant to make.
Claims (4)
1. the treating apparatus of a low concentration sulphur-containing exhaust gas is characterized in that, uses the device of being made up of waste gas pipeline road and boiler body to handle the low concentration sulphur-containing exhaust gas by burning.
2. low concentration sulphur-containing exhaust gas as claimed in claim 1 is characterized in that, the concentration of sulfurous gas is lower than its explosion limit concentration.
3. waste gas pipeline as claimed in claim 1 road is characterized in that, its pipeline itself and affiliated valve thereof, pipe fitting should have the ability of kinds of anti-sulfur corrosion.
4. boiler body as claimed in claim 1 is characterized in that, the tubulation of its air preheater should adopt the material of kinds of anti-sulfur corrosion to make, and the airduct of its sulphur-containing exhaust gas process also should be made kinds of anti-sulfur corrosion and handle.
