Be provided with a level meter in the methane voltage-stabilizing cabinet 101 described in the utility model, in order to monitor the gas position in the described methane voltage-stabilizing cabinet 101.
Biogas burner 102 described in the utility model, described biogas burner 102 comprises a control device, described control device specifically comprises: an auxiliary burner, a main burner, an igniter and a temperature sensor.The biogas that comes from methane voltage-stabilizing cabinet 101 flows to the biogas burner 102 of a 1200m3/h.The operation of biogas burner 102 is controlled automatically by the gas position of methane voltage-stabilizing cabinet 101.The operation of biogas burner 102 is made of an auxiliary burner (by solenoid control), main burner, a cover igniter and a temperature sensor.Hand-operated valve on the main burner pipeline is often opened in normal operation, in case biogas pressure reaches certain setting value, the auxiliary burner magnetic valve is opened, and igniter is namely lighted a fire, if temp probe detects high temperature, illustrates that the igniting flare is in burning.If the gas position of methane voltage-stabilizing cabinet 101 reaches certain level, lighting valve is opened automatically, and igniter starts automatically.If detect high temperature, illustrate that the igniting flare is in burning.When if methane voltage-stabilizing cabinet 101 gas positions reach main valve open position level, biogas burner 102 main valves are opened automatically, and biogas is lighted by the igniting flare, and methane voltage-stabilizing cabinet 101 gas positions slowly drop to certain level then, biogas burner 102 main valves can be closed automatically, and the igniting flare remains burning.The ignition temperature of biogas can be higher than 815 ℃.
Has a fan inlet in the aerating system described in the utility model.
The overflow water of sulphur settling vessel described in the utility model refluxes to hold and is connected with described bioreactor 202, and the sulphur outlet side of described sulphur settling vessel is connected with a sulphur sludge pump, and described stream sludge pump has a sulphur outlet side.
Further, the biological desulphurization scrubbing tower also is packed tower, and filled purpose is to increase the gas-liquid contact area.Biogas enters biological scrubbing tower 201(C601 after through water distributing can (V601)), biogas in scrubbing tower with top-down cleaning solution counter current contacting, make H2S in the biogas in biological scrubbing tower 201, be washed liquid and absorb.Gas after the desulfurization is discharged from the scrubbing tower top and is entered caustic scrubber.Place, biological scrubbing tower 201 gas outlets is arranged on the linear pressure table, and when system pressure was too high or too low, system stopped the circulating pump spray under the situation of reporting to the police, spray and interior formation vacuum under no press strip spare to prevent scrubbing tower.
In biological scrubbing tower 201, following reaction takes place in the H2S in the gas when being absorbed:
H2O+NaOH→?NaHS?+?H2O
Absorption liquid is collected back gravity in the bottom of scrubbing tower and is flowed into bioreactor 202, and cleaning solution pumps into scrubbing tower by circulating pump from reactor, and wherein part solution is used for scrubbing tower spray froth breaking.Flow switch is housed with the spray situation of continuous monitoring spray pump on the spray piping.The packing layer two ends are provided with manual clear water shower, are used for regularly clearing up the filler of biological scrubbing tower 201.The diameter of biological scrubbing tower 201 is 1.0m, highly is 19.0 meters.Empty tower gas velocity under the normal discharge is 0.3m/s, and bed stuffing height is 8m.
Further, the cleaning solution gravity from biological scrubbing tower 201 flows into bioreactor 202.Contain Thiobacillus in bioreactor 202 liquid phases, be converted into elemental sulfur at this sulfide.The carrier of no fixation of microbe in the reactor, and biological sulphur itself has served as the role of carrier.The complete mixed state that guarantees reactor is very crucial, relies on aeration to realize.Gas distribution system is arranged in the reactor, carry out aeration by air blast.In bioreactor 202, the key reaction of generation is as follows:
NaHS?+?1/2O2→?S?+?NaOH
By the control oxygen-supplying amount, when sulfide was converted into elemental sulfur, alkali obtained regeneration.The control of oxygen-supplying amount is by the oxidation-reduction potential in the control bioreactor 202, moved to realize by blower variable frequency, namely the oxidation-reduction potential value when on-line determination is lower than setting value, then needs the more air input in the reactor, and this moment, the running frequency of air blast increased; Otherwise when the oxidation-reduction potential value of on-line determination is higher than setting value, this moment, the running frequency of air blast reduced, and reduced the input of air capacity, thereby made oxidation-reduction potential remain within the suitable scope.Sulfide is oxidized in the process of elemental sulfur in bioreactor 202, except the control oxidation-reduction potential, also needs to control pH value, temperature, electrical conductivity and sulphur sludge concentration in the reactor.Under the higher situation of pH value, it is out of service automatically that NaOH adds pump, and when the pH value was on the low side, NaOH added pump operation continuously automatically, and when pH value was in 8.0 ~ 8.8 scopes, NaOH adds pump, and then the pulse of loading added according to the sulphur of air inlet.When too high or too low for temperature, system will start heat-exchanger rig automatically, make bioreactor 202 interior temperature remain on about 35 degree.Electrical conductivity raises then can open water compensating valve automatically, for reducing the electrical conductivity of system.
