Put the utility model discloses a kind of integral skid of marsh gas purifying, between methane-generating pit and biogas storage device, steam-water separator, desulfurizing tower, particle separator and the booster pump of integration are set gradually along biogas conveying direction.Individual unit is fixed on a skid-mounted device by the utility model, simple and convenient as long as unit can be used a whole set of purifier with pipeline connection.The product substantially increases desulfuration efficiency, so as to reduce erosion and the obstruction under water and hydrogen sulfide collective effect to metallic conduit, valve and flowmeter, the damage of sulfurous acid that the sulfur dioxide and vapor of sulfureted hydrogen burning generation is combined into methane fuelled engine is reduced in addition；The efficiency of desulfurization and decontamination is improved simultaneously, and energy-conserving and environment-protective reduce pollution of the harmful gaseous impurities such as sulfide to air.
Description
Technical field
The utility model is related to renewable sources of energy apparatus field, relates in particular to a kind of integral skid of marsh gas purifying and puts.
Background technology
Biogas, is various organic substances (for example, stalk, weeds, leaf, people's livestocks faces the like waste), empty in isolation
Under gas (reducing condition), and the temperature of matters, damp condition, a kind of incendivity gas is produced by the fermentation of microorganism
Body.Biogas by 50%-80% methane, 20-40% carbon dioxide, 0%-5% nitrogen, the hydrogen less than 1%, less than 0.4%
Other compositions such as oxygen and 0.1%-3% hydrogen sulfide.It can be seen that wherein content highest is methane.
At present, biogas such as has been widely used for heating, generated electricity the project, and when carrying out processed to biogas, and it is from anaerobism
During installation for fermenting output, particularly in middle temperature or hot fermentation, substantial amounts of hydrogen sulfide is carried.It is a large amount of due to also having in biogas
Vapor exist, the hydrogen sulfide collective effect in water and biogas accelerates the corrosion of metallic conduit, valve and flowmeter and stifled
Plug.In addition, the sulfur dioxide produced after sulfureted hydrogen burning, generation sulfurous acid is combined with the vapor in combustion product, can be serious
Methane fuelled engine is damaged, and can also cause the pollution to atmospheric environment, health is influenceed.And conventional dry desulfurization uses oxygen
Change iron as desulfurizing agent, short-term desulfuration efficiency can reach 60%-70%, inefficient, and the term of validity is short, it is necessary to periodically enter pedestrian
Work changes desulfurizing agent；The methane concentration of purification is not also high.And existing desulfurization dewatering equipment needs to be installed at the scene, effect
Rate is low, high cost.
Utility model content
Goal of the invention：The utility model provides a kind of by supercharging, desulfurization, decontamination and the integrated marsh gas purifying one of dehydration
Skid is put.
Technical scheme：To achieve the above object, the integral skid of a kind of marsh gas purifying of the present utility model is put, located at methane-generating pit
Between biogas storage device, the integral skid put along biogas conveying direction be disposed with steam-water separator, desulfurizing tower,
Grain separator and booster pump.
Preferably, provided with the wet sprinkling device using sodium carbonate as desulfurizing agent in the desulfurizing tower.By further setting
Automated packing device is counted, may be such that desulfuration efficiency reaches 90%-95%.
The automated packing device is located between micro computer and desulfurizing tower, and when filler is inadequate in desulfurizing tower, automatic alarm is simultaneously
Filler is added to working condition.
The drying chamber for adsorb chamber provided with accommodate aluminum oxide first in the soda flow divider, accommodating hygroscopic salt
Room and the second absorption chamber for accommodating activated carbon.It is molten that the hygroscopic salt includes but is not limited to lithium-bromide solution, lithium chloride
The combination of any one or more of liquid, calcium chloride solution.Aluminum oxide is high as adsorbent adsorption efficiency, and activated carbon is adsorbable miscellaneous
Matter and a small amount of ammonia, are greatly improved the efficiency of dehydration decontamination.
Preferably, the steam-water separator is provided with the self-draining cock of water drain when water exceedes container reserves 2/3.This
On the one hand the design of sample can ensure the normal operation of whole steam-water separation tank, prevent that what is be stopped because of hypervolia shows
As；On the other hand people's cost is reduced, it is not necessary to which whether water yield of the someone constantly in separation of concerns tank influences dehydration.
The steam-water separator, desulfurizing tower, the air inlet of particle separator are located at bottom, and gas outlet is located at top.Each
The interconnection of part is realized a variety of function settings on a skid-mounted device jointly.From multiple wherein in particle separator
Conjunction amine aqueous solution is absorbent, and its purification methane content passed through is up to more than 97%, and hydrogen sulfide content is less than 10ppm, and moisture content is low
In 0.2g/Nm3。
Beneficial effect：Individual unit is fixed on a skid-mounted device by the utility model, as long as a whole set of purifier will be each
Individual unit can be used with pipeline connection, simple and convenient.The product substantially increases desulfuration efficiency, so as to reduce water and vulcanization
Erosion to metallic conduit, valve and flowmeter and obstruction under hydrogen collective effect, reduce the two of sulfureted hydrogen burning generation in addition
Damage of the sulfurous acid that sulfur oxide and vapor are combined into methane fuelled engine；The effect of desulfurization and decontamination is improved simultaneously
Rate, energy-conserving and environment-protective reduce pollution of the harmful gaseous impurities such as sulfide to air.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of integral skid of marsh gas purifying is put, it is defeated along biogas between methane-generating pit 1 and LNG air accumulators 2
Direction is sent to be disposed with steam-water separator 3, desulfurizing tower 4, particle separator 5 and booster pump 6.
Provided with the wet sprinkling device using sodium carbonate as desulfurizing agent in desulfurizing tower 4.By further designing automated packing
Device, may be such that desulfuration efficiency reaches 90%-95%.
