Operation principle of the present invention:
The regeneration acid gas enters into the middle gas distribution absorber of integrated reactor; Evenly distribute through the cross gas pipe acid gas of will regenerating; Form micro-bubble, from bottom to top with the gas distribution absorber in the lean solution haptoreaction, lean solution absorbs the hydrogen sulfide in the acid gas; The acid gas of taking off after the hydrogen sulfide reaches the emptying standard, and the drain of the absorption and regeneration tank top through integrated regeneration reactor directly is discharged in the atmosphere; Lean solution in the gas distribution absorber forms rich solution after having absorbed hydrogen sulfide; Rich solution gets in the absorption and regeneration jar of integrated reactor from gas distribution absorber top under pneumatically supported effect; Air compressor makes it become regeneration the rich solution oxidation through the equally distributed air of annular gas pipe in the absorption and regeneration jar air and generates lean solution; Under the effect of air supporting and difference in specific gravity, form convection circulation, lean solution gets in the gas distribution absorber; Form drusen when generating lean solution; Drusen sinks to being pooled to the absorption and regeneration jar awl bottom of integrated reactor, and the purging air compressor regularly purges air to drusen through shower nozzle, and the sulphur slurry that drusen and doctor solution form flows into the sulfur filtration sled through pipeline; The sulphur slurry at first gets into vacuum-type drum filter; Under the swabbing action of vavuum pump; Doctor solution in the sulphur slurry gets into gas-liquid separator; The surface that drusen accumulates in vacuum-type drum filter forms sulphur cream, but sulphur cream entrucking outward transport is returned integrated reactor through filtrate pump with the doctor solution in the gas-liquid separator again; To be stored in the absorption liquid that absorbs in the flow container through dosing pump and add in the integrated reactor, carry out circular treatment, finally almost all deviate from the sulphur in the regeneration acid gas.
Through retrieval both at home and abroad, do not find the integrated form sulfur recovery facility identical as yet with the present invention, the present invention has improved the organic efficiency of sulphur in the acid gas; Reduce occupation area of equipment significantly more than 50%; Shorten the engineering construction cycle, reduced construction costs, made things convenient for production management.
Compared with present technology the present invention has the following advantages:
1, this sulfur removal technology is simple in structure, reasonable in design, and is whole integrated, and equipment volume is little, can whole process unit layout on three sled pieces, can form serial approved product according to process lot size, and is on-the-spot quick and easy for installation, do not influence ordinary production.
2, adopt advanced integrated reactor, acid gas absorption and solution regeneration are combined together, reduce amount of equipment, improve operational efficiency.
3, with the regeneration of regenerated acid qi exhaustion sulphur and solution, sulfur filtration separates, medicament replenishes etc. combines, sulfur removal technology can wholely become to prize, compact equipment, volume are little, occupation of land less, cost is low, production run and desulphurization cost are low.
