The utility model can change discontinuous oxygen generation into continuous discontinuous oxygen in sequence in the same time, and when air inlets the adsorption towers, a conical surface gas distribution device is added to make molecular sieves utilized fully. A pressure controller can be adjusted at the oxygen output end to be matched with the pressure of oxygen generation of the adsorption towers to make output oxygen continuous. The utility model has the advantages of constant pressure, simple structure and easy installation, and the energy consumption and the noise can be reduced.
Description
The utility model relates to a kind of pressure swing adsorption method separation of air, with the device of realizing that oxygen, nitrogen separate, specifically a kind of transformation adsorption of oxygen enrichment facility.
In the prior art as shown in Figure 1, when compressed air through three-way connection 1 ', magnetic valve 2 ' unlatching, enter adsorption tower 3 ' time magnetic valve 4 ' unlatching, the residual gas of adsorption tower 5 ' interior is through exhaust silencer 6 ' enter atmosphere, by adsorption tower 3 ' realization oxygen, dense oxygen after nitrogen separates through check valve 7 ' enter finished product vacuum tank 8 ', this moment magnetic valve 2 ', 4 ' close, magnetic valve 9 ' action, adsorption tower 3 ', adsorption tower 5 ' all press, utilize this EGR, finish supercharging, exhaust---is produced oxygen---and is all pressed, can finish a stopping pregnancy oxygen, but this device molecular sieve utilization rate is low, non-oxygen-production gas in above-mentioned pressure equalizing, only form a stopping pregnancy oxygen pattern, and the pipeline assembling is loaded down with trivial details, easy break-down.
The purpose of this utility model just provides a kind of increase and produces the oxygen rate, and molecular sieve utilization rate height is simple in structure, easy for installation, cuts down the consumption of energy and noise, transformation adsorption of oxygen enrichment facility that cost is low.
The utility model is achieved in that it comprises that the adsorption tower, exhaust silencer, moisture trap, vacuum tank, air compressor and the molecular sieve that connect by the absorption pipeline constitute, its main points are that it also comprises the electric automatically controlled plate of time-delay, two automatically controlled multichannel combinaing valve body, be provided with airflow-distribution board at the adsorption tower airintake direction, air cleaner is connected with the air compressor air inlet.
The utility model transformation adsorption of oxygen enrichment facility adopts two automatically controlled multichannel combination valves, and volume is little, makes pipeline easy to connect.
The utility model transformation adsorption of oxygen enrichment facility, increased conical surface airflow-distribution board at the adsorption tower airintake direction, eliminated effectively and to have formed the molecular sieve adsorption dead angle when jet angle that high pressure draught moment forms enters adsorption tower, improve the utilization rate of molecular sieve, in the adsorption tower of equivalent amount molecular sieve, can improve the oxygen rate of producing.
The utility model transformation adsorption of oxygen enrichment facility is connected to the adjustable pressure controller on the said vacuum tank, cooperate absorption to produce oxygen pressure, makes oxygen vacuum tank internal pressure stable, to guarantee the continuity and the constant pressure of output oxygen.
The utility model transformation adsorption of oxygen enrichment facility, the quantitative flow divider that absorption is installed on the pipeline charges into the air of 0.26～0.28Mpa pressure and quantity to the adsorption tower of finishing the desorb work step, so that it is uninterrupted to produce oxygen during the adsorption tower conversion.
Further narrate the utility model below in conjunction with drawings and Examples:
Fig. 1 is the prior art general structure schematic diagram relevant with the utility model;
Fig. 2 is the utility model general structure schematic diagram;
Fig. 3 is the utility model compressor (17) partial schematic diagram;
Fig. 4 is the valve pocket distribution pipeline schematic diagram of the utility model combinaing valve body (4):
Fig. 5 is the utility model combinaing valve body (4) A-A partial schematic diagram.
As Fig. 2, shown in Figure 3, air enters oil-free air compressor 17 through air cleaner 6, send into compressor 17 superchargings by compressor inlet suction port 17-1, after reaching the compressed machine exhaust outlet of 0.26Mpa pressure 17-2 and delivering to moisture trap 7 and separate by pipeline, send into air inlet 22 (as shown in Figure 4) on the combinaing valve body 4 by pipeline, the open and close of combinaing valve body 4 each passage is by being attached thereto the automatically controlled plate 3 that connects by set order and time, send two the magnetic head 4-1 and the 4-2 that put combinaing valve body 4 tops to go up (as shown in Figure 5) voltage, behind magnetic head 4-2 coil electricity, produce high-intensity magnetic field, overcome the pressure of stage clip 4-2-2, magnetic core in the stage clip 4-2-2 is upwards mentioned, and the connecting plate 4-2-3 that has two boss that will be fixed on its bottom draws high, all have sealing ring on each boss, no matter how to move up and down, can both closely cooperate with valve seat shell 4-2-4, make the valve pocket in the valve seat shell 4-2-4 be in sealing state all the time, after connecting plate 4-2-3 is by the magnetic core pull-up, the pressure that diaphragm stage clip 4-2-5 is pressed to diaphragm 4-2-6 reduces suddenly, air after this moment compression impacts sealing of diaphragm 4-2-6 through the distribution pipeline of combination valve high pressure admission mouth 22 and enters valve pocket and input to adsorption tower 1, realize oxygen, after the nitrogen separation was finished, oxygen entered vacuum tank 5 by the check valve 9 at top through oxygen pipeline 10.Finish at adsorption tower 1 and to utilize the pipeline of UNICOM between two adsorption towers in the adsorption process, make pressurisings in the adsorption tower 2, when adsorption tower 2 beginning desorbs, realize immediately producing oxygen, reduced all pressures work step of original device, reach continuous product oxygen.
Adopt the utility model, successively finish between change stopping pregnancy oxygen in can be at one time and be product oxygen continuously, improved product oxygen rate, and when entering adsorption tower, air increased conical surface airflow distribution device, molecular sieve is fully used, produce the oxygen pressure fitted at oxygen output adjustable pressure controller and adsorption tower, make output oxygen continuous, constant pressure.The utility model is simple in structure, easy for installation, cuts down the consumption of energy and noise, has improved economic benefit.
