The present invention also comprises a condensation water tank 103, and described condensation water tank 103 is connected with the bottom of described methane voltage-stabilizing cabinet 101, the water of separating out in order to collect the interior biogas of methane voltage-stabilizing cabinet 101.
Be provided with a liquid-level switch and a water system in condensation water tank 103 of the present invention, in order to form a water seal, described water seal is leaked from drainpipe in order to prevent biogas.
Biogas outlet of the present invention be connected and described methane voltage-stabilizing cabinet 101 between be provided with a biogas flow monitoring equipment.
Methane voltage-stabilizing cabinet 101 of the present invention specifically comprises: a tank body and a floating roof, described floating roof is connected with the film of described tank body by a polyester textile.Methane voltage-stabilizing cabinet 101 is comprised of cylinder of steel and a floating roof of a tool anticorrosive paint.The counterweight at floating roof top will be set the gauge pressure that gas system produces a 2.5 ~ 3.0KPa, and floating roof is connected with the film of tank body by a telescopic polyester textile, so floating roof can move up and down.The volume of methane voltage-stabilizing cabinet 101 can increase or reduce and need not to change the interior pressure of gas system like this.The gas position of methane voltage-stabilizing cabinet 101 is by the level meter continuous monitoring.
Be provided with a level meter in methane voltage-stabilizing cabinet 101 of the present invention, in order to monitor the gas position in described methane voltage-stabilizing cabinet 101.
Biogas burner 102 of the present invention, 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 high temperature detected, 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 then methane voltage-stabilizing cabinet 101 gas position slow decreasings are to certain level, biogas burner 102 main valves meeting autoshutdowns, and the igniting flare remains burning.The ignition temperature of biogas can be higher than 815 ℃.
Has a fan inlet in aerating system of the present invention.
The overflow water of sulphur settling vessel of the present invention 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 is also 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 biogas be washed liquid in biological scrubbing tower 201 and absorb.Gas after desulfurization enters caustic scrubber from scrubbing tower top discharge.Biological scrubbing tower 201 places, gas outlet are arranged on the linear pressure table, and when system pressure was too high or too low, system sprayed and interior formation vacuum under the with no pressure condition to prevent scrubbing tower in the situation that warning stops the circulating pump spray.
In biological scrubbing tower 201, following reaction occurs in the H2S in gas when being absorbed:
H2O+NaOH→NaHS?+?H2O
Absorption liquid gravity after collect the bottom of scrubbing tower flows 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 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, is highly 19.0 meters.Empty tower gas velocity under 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.In reactor, without the carrier of fixation of microbe, 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 reactor, carry out aeration by air blast.In bioreactor 202, the key reaction of generation is as follows:
NaHS?+?1/2O2→?S?+?NaOH
By controlling oxygen-supplying amount, when sulfide was converted into elemental sulfur, alkali was regenerated.The control of oxygen-supplying amount is by controlling the oxidation-reduction potential in bioreactor 202, moved to realize by blower variable frequency, the oxidation-reduction potential value of namely working as on-line determination needs more air input lower than setting value in reactor, this moment, the running frequency of air blast increased; Otherwise higher than setting value, this moment, the running frequency of air blast reduced, and reduced the input of air capacity when the oxidation-reduction potential value of on-line determination, thereby made within oxidation-reduction potential remains on suitable scope.In the interior sulfide of bioreactor 202 is oxidized to the process of elemental sulfur, except controlling oxidation-reduction potential, also need to control pH value, temperature, electrical conductivity and sulphur sludge concentration in reactor.In the higher situation of pH value, it is automatically out of service that NaOH adds pump, and when the pH value was on the low side, NaOH added the operation of pump Automatic continuous, and when pH value was in 8.0 ~ 8.8 scopes, NaOH adds pump, and 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 the interior temperature of bioreactor 202 remain on about 35 degree.Electrical conductivity raises can open water compensating valve automatically, for reducing the electrical conductivity of system.
In sum, owing to having adopted technique scheme, the invention discloses a kind of marsh gas treating system in order to solve the problem that lacks a kind of marsh gas treating system that can effectively process the biogas of changing food waste generation and effectively utilize in prior art, by biogas is carried out a series of processing, realize the good processing of biogas and effectively utilize.
