Abstract
This application belongs to biogas fermentation technical field, concretely relates to marsh gas purification system. This system is including the feed gas input tube, feed gas pretreatment tank, gas pressurized device and the gaseous purifier that connect gradually, feed gas pretreatment tank lower part is equipped with the drain, and feed gas pretreatment tank middle part is equipped with the filter screen simultaneously, gaseous purifier specifically adopts membrane separation decarbonization device. The marsh gas purification system that this application provided, can be comparatively effective with have corresponding to drive gas and solid impurities such as CO2 in the marsh gas, H2S, and the body of the methane gas behind purification both can directly use, preserved or shift the transportation behind the compressing that also can step forward to reduce the stable influence inadequately of marsh gas when production marsh gas output, thereby the extend use who produces for marsh gas further establishes good applied basis.
Description
Technical field
The application belongs to technical field of methane fermentation, and in particular to a kind of patent application of marsh gas purifying purification system.
Background technology
In prior art, obtained with realizing the theory that resource is maximally utilized by biomass waste material ferment preparation of sludge gas
Deeply promote, but be mostly to be prepared from based on anaerobical fermentation technique, prepared by this mode in existing biogas technology of preparing
Biogas, in its composition in addition to main energy sources gases methane, also comprising the CO that ratio is higher2、H2The foreign gases such as S, thus result in
Its combustibility is not sufficiently stable, and add in sweat is easily affected by natural environment temperature, and ferment effect is not sufficiently stable, and then
Biogas output is caused to be not sufficiently stable, thus resulting in Methane Resources cannot stably utilize.For this defect, a kind of biogas is developed net
Change purification system, consequently facilitating using and reclaiming storage for Methane Resources just has highly important application value.
The content of the invention
The application purpose is to provide a kind of marsh gas purifying purification system, by the systematic difference, it is possible to obtain purer
Net methane gas, so as to ensure stability when using as the energy, and the methane gas for purifying also allows for further compression
Storage is used as other energy.
Details are as follows for the technical scheme that the application is taken.
A kind of marsh gas purifying purification system, increases including the unstripped gas input pipe, feed gas preprocessing tank, gas being sequentially connected
Pressure device and gas cleaning plant；
The feed gas preprocessing tank bottom is provided with sewage draining exit, while feed gas preprocessing tank middle part is provided with filter screen；Filter screen
On be loaded with unformed hydroxyl oxidize iron material, with to contained H in unstripped gas2S gas removals；And unstripped gas is in pretreatment tank
Portion rises and temperature drop with height, and steam and particulate species impurity gradually condense and to be deposited in pretreatment tank bottoms in unstripped gas
Portion, and then discharged by sewage draining exit；
The feed gas preprocessing tank, in decision design, can also preposition vane type string filter separator, to carry out to unstripped gas
Preliminary filtration treatment；
After pretreatment unstripped gas is entered in gas cleaning plant Jing after gas pressurized device with relatively stable flow, from
And guarantee stablizing for system operation；
The gas cleaning plant, can specifically adopt membrance separation decarbonization device（CRU）, the hollow-fibre membrane in the device can
By CO in biogas2Preferably separate.
In decision design, gas cleaning plant can also be with CO2Retracting device connects, by CO2After impurity and purification, can conduct
Industrial production raw material is used.
Further preferably in design, gas cleaning plant 4 is connected with gas compressing apparatus 5, consequently facilitating first after purifying
Alkane gas compression becomes liquid, consequently facilitating storage and transfer transport.
In general, marsh gas purifying purification system provided herein, more can remove effectively and targetedly natural pond
CO in gas2、H2The gases such as S and solid impurity, and the methane gas after purification, both can directly use, and can also enter one
Transport is preserved or shifted to step compression after processing, so as to reduce the impact that biogas output during biogas production is not sufficiently stable, from
And be that the utilization and extention of biogas production further establishes good application foundation.

The bottom of feed gas preprocessing tank 1 is provided with sewage draining exit 6, while the middle part of feed gas preprocessing tank 1 is provided with filter screen；Filter
Unformed hydroxyl oxidize iron material is loaded with the net, with to contained H in unstripped gas2S gas removals；
The feed gas preprocessing tank, in decision design, can also preposition vane type string filter separator, to carry out to unstripped gas
Preliminary filtration treatment；
The gas cleaning plant 4, can specifically adopt membrance separation decarbonization device（CRU）, the hollow-fibre membrane in the device
Can be by CO in biogas2Preferably separate.
In decision design, gas cleaning plant 4 can also be with CO2Retracting device connects, by CO2After impurity and purification, can conduct
Industrial production raw material is used.
Further preferably in design, gas cleaning plant 4 is connected with gas compressing apparatus 5, consequently facilitating first after purifying
Alkane gas compression becomes liquid, is easy to preserve and shift transport.
During carrying out practically, unstripped gas（Biogas）Entered in pretreatment tank 2 by input pipe 1, in pretreatment tank 2, unstripped gas
Jing after desulfurization, de- vapour, dedirt pretreatment, entered in purifier 4, in purifier with relatively stable flow after pressurization
CO in 4, in biogas2Efficiently separated with methane, transport can be preserved or shifted to methane after pressurized liquefaction after separation, be easy to
Later use, and separated CO out2, also can be used as industrial production raw material after centralized recovery.
