Description
Technical field
The invention belongs to the dehydration device of methane in biogas production equipment scope, especially biogas production technique.
Technical background
The biogas that ordinary person's work is produced contains saturated steam, and dew-point temperature is reached in biogas gas pipeline to be occurred
Condensed water can hinder biogas to circulate；Water vapor in methane can reduce biogas combustion calorific value；Vapor is fired with hydrogen sulfide in methane
The sulfur dioxide generated after burning is combined into sulfurous acid, can corrode metal equipment, pollutes air, influences health.Therefore, biogas
Dehydration is a facility indispensable in biogas engineering, and the moisture how more cost-effectively removed in biogas is always people's
It pursues a goal.The cardinal principle and basic skills of biogas dehydration are cooled down for the vapor in biogas, and dew-point temperature is reached,
It forms condensed water and is separated and discharged.Existing biogas gas-water separator is by controlling biogas flow velocity and pressure change, realizing and hold
Cooling variation is generated in device, allows the vapor in biogas to condense sedimentation, and biogas is made to be filled out in dewatering container inward eddy and through strainer
Material separation vapor.The dehydrating effect of the dehydration device is better than conventional cryophorus effect, but dehydrating effect is still not achieved biogas and enters
Gas distributing system requirement, it is necessary to coordinate other adsorbents or absorbent to be further dehydrated, dewatering process is loaded down with trivial details, of high cost.Together
When, the biogas gas-water separator is without positive and negative pressure pressure-limiting function.
Invention content
This purpose invented in fact is provided for biogas gas-water separation new in existing biogas gas-water separator technical foundation
Low-temperature receiver, and increase positive pressure pressure limiting and negative pressure pressure-limiting function.
The invention is realized in this way：By biogas gas-water separation function setting in upper chamber, by condensed water Auto-drainage work(
Can setting in lower chambers, so that it is volatilized upwards flowing along epicoele chamber outer wall by water-absorbent material the condensed water of collection, or upper
Chamber outer patch cooling film, and flow regine effect and the spring effect of water are used respectively, by positive pressure pressure limiting and negative pressure pressure-limiting function
It is arranged in Auto-drainage component.There are three types of schemes by the present invention：
The first scheme is that the condensed water using collection is the device of cooling low-temperature receiver and positive and negative pressure pressure limiting medium：Including upper
Chamber and lower chambers have in upper chamber filter screen filling material, upper chamber bottom side to have air inlet pipe, have tangent line air admission hole on the inside of air inlet pipe, push up
Portion has escape pipe, upper chamber bottom to have the water service pipe for extending to lower chambers lower part with cavity of resorption ceiling junction, have row on the upside of lower chambers
The mouth of a river, upper chamber and lower chambers are externally provided with the set tank of bottom end closure, and set tank top has head cover, head cover to have uniformly distributed gas vent, epicoele
There is water-absorbent material between room, lower chambers and set tank, covers the uniformly distributed osculum having around tank with discharge outlet sustained height.
There are threeway drainpipe, branch pipe to extend to set pot bottom between set tank on the upside of lower chambers, threeway drainpipe is another
End is bent upwards.
The device that it is cooling low-temperature receiver that second scheme, which is using cooling film, and condensed water is positive and negative pressure limit medium：Including
Upper chamber and lower chambers have in upper chamber filter screen filling material, upper chamber bottom side to have air inlet pipe, have tangent line air admission hole on the inside of air inlet pipe,
Top has escape pipe, upper chamber bottom to have the water service pipe for extending to lower chambers lower part with cavity of resorption ceiling junction, have on the upside of lower chambers
Discharge outlet posts cooling film outside upper chamber.
Cool down film, is a kind of new product that can be cooled down for object using illumination, and the object covered by cooling film compare ring
Border temperature can reduce by 33~42 DEG C, and every square metre only more than 3 yuan.Cooling film is mainly used for air-conditioning, freezer cooling, this is answered to extend
With.It is overturn and is sticked, can also make to be covered by heat, the condensed water in dehydration device is avoided to freeze failure.
It is cooling low-temperature receiver and the device that spring is positive and negative pressure pressure limiting medium that the third scheme, which is using cooling film,：Including
Epicoele and lower chambers have filter screen filling material, upper chamber bottom side to have air inlet pipe, there is tangent line air admission hole, top in air inlet pipe in upper chamber
It is biogas air water safety automation separator to have escape pipe, lower chambers, and there are connecting tube, lower chambers both sides in upper chamber bottom with cavity of resorption ceiling
There are snorkel, both sides snorkel to have positive pressure pressure limiting valve and negative pressure pressure limiting valve respectively.Biogas air water safety automation separator is a kind of
The prior art.
The positive effect of the present invention is：It (1), can be with due to increasing condensed water cooling low-temperature receiver and cooling film cools down low-temperature receiver
So that the vapor dew point in biogas is significantly reduced, biogas dehydrating effect is greatly improved.(2) since dehydrating effect spy is good, from aerogenesis
Device to gas storage device or from wet type gas storage device to gas equipment between gas pipeline, only need to install one.(3) by
Have the function of that anti-positive and negative pressure transfinites simultaneously in the dehydration device, thus saves equipment cost.(4) when the gas in dehydration device
Pressure is when transfiniting, can separately collection storage is not only energy saving but also extra biogas can be prevented in line to environment for using by extra biogas
Pollution.(5) above two cooling and dewatering method does not have to external energy, saves operating cost.
