Description of drawings
The structured flowchart of a kind of biological desulphurization treating apparatus that Fig. 1 provides for the utility model.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, the structured flowchart of a kind of biological desulphurization treating apparatus that provides for the utility model is by scrubbing tower 1, bioreactor 2, settling vessel 3, circulating pump 4, air blast 5, sulphur pump 6, sulfur drain pipe 7, replenish water valve 8, pH on-line determination instrument 9, redox position indicator 10, liquid level gauge 11 and gas distribution system 12 and form.
The cleaning solution bypass outlet of scrubbing tower 1 connects the cleaning solution reflux inlet of bioreactor 2, the outlet of bioreactor 2 connects the spray inlet of scrubbing tower 1 and the entry to mixed solution of settling vessel 3 by circulating pump 4, one end of air blast 5 is connected by the gas distribution system 12 in pipeline and the bioreactor 2, bioreactor 2 connects additional water valve 8, the purified liquor outlet of settling vessel 3 connects the clear liquid inlet of bioreactor 2, and the elemental sulfur outlet of settling vessel 3 connects the biological sulphur reflux inlet and the sulfur drain pipe 7 of bioreactor 2 by sulphur pump 6.Also be connected with pH on-line determination instrument 9, redox position indicator 10 and liquid level gauge 11 on the bioreactor 2.
Operation principle of the present utility model is as follows:
Biogas/waste gas at first enters scrubbing tower 1, gas in scrubbing tower 1 with the cleaning solution counter current contacting, hydrogen sulfide is washed liquid and absorbs.Gas after the desulfurization is discharged from scrubbing tower 1 top.Cleaning solution pumps into biological scrubbing tower by circulating pump 4 from the degas zone of bioreactor 2, and part water is used for reactor spray froth breaking.Cleaning solution is collected in the bottom of scrubbing tower 1 and is relied on gravity to flow back to bioreactor 2 again.Contain Thiobacillus in the liquid phase of bioreactor 2, be converted into elemental sulfur at this sulfide.The carrier of no fixation of microbe in the bioreactor 2, and biological sulphur itself has served as the role of carrier, plays the effect of further cleaning.Air blast 5 blasts air and carries out aeration by the gas distribution system 12 in the bioreactor 2.Cleaning solution in the bioreactor 2 is continuously pumped into settling vessel 3 by circulating pump 4, and The product sulfur is separated with cleaning solution in this unit, and The product sulfur is extracted out to treat further processing by sulphur pump 6.The clear liquid overflow of settling vessel 3 is to bioreactor 2.
And the effect of pH on-line determination instrument 9 is: monitoring pH of mixed value; The effect of oxidation-reduction potential instrument 10 is: monitoring mixed liquor oxidation-reduction potential value guarantees that sulfide is converted into sulphur simple substance; The effect of liquid level gauge 11 is: the liquid level of monitoring bio reactor, and control lifting rate and rate of water make-up.
