Description
Technical field
The utility model relates to a kind of structure of carbon molecular sieve nitrogen-making machine adsorption tower.
Background technology
Mine nitrogen fire extinguishing essence injects a certain amount of nitrogen in the oxidized zone of goaf or in flame range, makes its oxygen content drop to less than 5%, reaches the object of fire extinguishing and suppression gas explosion.Compared with other fire extinguishing methods of mine, be better than traditional slip casting preventing and extinguishing fire technology with nitrogen preventing and extinguishing fire technology; Note nitrogen technique is quick, rapid.Nitrogen can be filled in the oxidized zone of goaf or each corner of flame range by rapid permeability.And grouting process, due to slurry in the oxidized zone of goaf or the flowing of flame range uneven by floor, top board emits piles up the impact of unequal factor, can be formed " flowing ditch ", thus " coal body " surface can not evenly, all sidedly be covered, fail really to play " completely cutting off " oxygen, prevent the effect of coal oxidation spontaneous combustion.So the anti-technology of going out of nitrogen has its better effect.
Pressure swing adsorption is the new technology for gas purification, Separation & Purification grown up in recent ten years.The advantages such as this technical equipment is simple, easy to operate, automaticity is high, small investment, aerogenesis are fast, be widely used, the fire prevention in colliery is exactly a key areas wherein.
Pressure-variable adsorption carbon molecular sieve nitrogen-making principle:
O
2and N
2be all nonpolar molecule, both kinetic diameters and boiling point are very close.Due to the steric effect of molecular sieve, there is the carbon molecular sieve layer of microcellular structure to O
2and N
2there is eutectoid content phenomenon.Therefore realize oxygen, nitrogen separation is more difficult.But carbon molecular sieve layer belongs to the adsorbent of speed divergence type, O
2and N
2diffusion velocity on carbon molecular sieve layer surface is different, due to N
2kinetic diameter be greater than O
2kinetic diameter, so O
2n is greater than in the diffusion velocity on carbon molecular sieve layer surface
2in the diffusion velocity on carbon molecular sieve layer surface.O
2preferentially adsorb by carbon molecular sieve layer, and N
2never enrichment in Adsorption Phase.PSA nitrogen has used this principle.The Fast Process of composition pressurized adsorbent and decompression desorb.Thus acquisition product nitrogen gas.
But the effect of the absorption tower adsorbs of carbon molecular sieve nitrogen-making machine of the prior art bad, carbon molecular sieve particles also unsaturation time just can not adsorb again and produce nitrogen.
Utility model content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of carbon molecular sieve nitrogen-making machine adsorption tower, is provided with dual adsorption structure, significantly can improves adsorbance in this adsorption tower.
The technical scheme that the utility model adopts is:
A kind of carbon molecular sieve nitrogen-making machine adsorption tower, comprises adsorption tower body, is arranged on the entrance of adsorption tower body lower end, is arranged on the outlet of adsorption tower body upper end, is arranged on the dividing plate of adsorption tower body lower part and is arranged on the carbon molecular sieve cylinder of adsorption tower body upper part; Being positioned at more than dividing plate, being positioned at the space of below carbon molecular sieve cylinder is carbon molecular sieve particles storage chamber, for holding carbon molecular sieve particles; Dividing plate has several pores, the aperture of pore is less than carbon molecular sieve particles.
Further, dividing plate is opened leachy circular flat board by one piece and is formed.
Further, dividing plate one invertedly drives the leachy conical surface.
Further, carbon molecular sieve cylinder is top closure, bottom opening and sidewall have the cylindrical drum of several square openings.
It should be noted that, when applying the utility model and carrying out production nitrogen, compress and the air of purified treatment, adsorption tower is entered from entrance, under the effect of air pressure, gas (with pressure), by the pore on dividing plate, blows carbon molecular sieve particles, thus carbon molecular sieve particles is fully contacted with air; Then the gas after carbon molecular sieve particles preliminary purification, then enter in carbon molecular sieve cylinder and again purify; Sidewall due to carbon molecular sieve cylinder has several square holes, further increases the contact area with gas, thus this carbon molecular sieve nitrogen-making machine adsorption tower, good absorbing effect, the constant absorption time is long.
