Description
Technical field
The utility model relates to a kind of nitrogen-making device, particularly the making nitrogen by pressure swing adsorption device.
Background technology
The nitrogen-making device of existing transformation absorption is generally two tower structures, concrete, this device comprises an adsorption tower group of mainly being made up of two adsorption towers that are connected in parallel.In general, two adsorption towers in the adsorption tower group are provided with concurrently, and two adsorption towers all have an air intake valve that is connected with the air inlet total valve and an outlet valve that is connected with the nitrogen outlet total valve separately, are connected in parallel thereby reach; In addition, also respectively carry be in parallel an and stripping gas outlet valve that be connected with corresponding air intake valve on two adsorption towers, close above-mentioned air inlet outlet valve and open the stripping gas outlet valve and just make adsorption tower be transformed into the desorption reproduced state from adsorbed state.Can also be connected with muffler on the stripping gas outlet valve.Be mounted with a certain amount of adsorbent in the above-mentioned adsorption tower, running parameter such as pressure decided the amount of the adsorbent that is loaded when those skilled in the art can be according to system nitrogen amount, nitrogen product purity, system nitrogen.
During nitrogen-making device work, the alternately absorption of two adsorption towers of above-mentioned adsorption tower group, desorption regeneration.Promptly open the air intake valve of air inlet total valve and one of them adsorption tower, compressed air enters this adsorption tower, this adsorption tower begins adsorption process, the airborne oxygen of adsorbents adsorb, remaining nitrogen is successively by its outlet valve, the nitrogen outlet total valve is discharged (being discharged to storage tank or the directly use of discharging back), after the adsorbent in this adsorption tower is saturated, close the air inlet and the outlet valve of this adsorption tower and open its stripping gas outlet valve, the oxygen that is adsorbed agent absorption discharges to the external world, this adsorption tower enters the process of desorption regeneration, open the air inlet and the outlet valve of another adsorption tower simultaneously, another adsorption tower begins above-mentioned adsorption process.Two adsorption tower alternations so repeatedly.
Before the adsorption tower that is in adsorbed state is transformed into the desorption reproduced state, can close air inlet total valve and outlet total valve, open the air intake valve and the outlet valve of another adsorption tower, by the adsorption tower that is in adsorbed state when saturated (generally be) pressure ramp is gone into described another adsorption tower to improve its pressure, this process is commonly referred to pressure equalizing.
When system nitrogen amount is big, need to strengthen the volume of adsorption tower on the one hand, at first improved and manufactured cost, and when the volume of adsorption tower was too huge, the dead space in the adsorption tower also became greatly, the utilization ratio of adsorbent descends, and the consumption of air also increases; In addition, the size of absorber strengthens, and the adsorbent hold down gag is required to improve greatly; On the other hand, need to strengthen the latus rectum of gas pipeline, cause the manufacturing cost of air inlet/outlet valve to increase, also improved sealing property requirement valve.In addition, when device integral body strengthens, when bringing very big inconvenience, also increased production cost to operation and maintenance.
Summary of the invention
For solving above-mentioned technical problem, the utility model provides a kind of making nitrogen by pressure swing adsorption device, it comprises the adsorption tower group, and described adsorption tower group is connected in parallel by at least two adsorption towers that alternately adsorb and regenerate and forms, and wherein: this device comprises a plurality of adsorption tower groups that are connected in parallel.
Adopt the nitrogen-making device of technique scheme, when system nitrogen amount is big, just do not need correspondingly to strengthen the volume of adsorption tower, also do not need to strengthen the latus rectum of gas pipeline.For example, when system nitrogen amount exceeds the load of an adsorption tower group, can make unstrpped gas be diverted to a plurality of adsorption tower groups that are connected in parallel.Therefore, only need be according to system nitrogen the amount amount of unstrpped gas and the system nitrogen ability of each adsorption tower group in other words, the adsorption tower group of opening respective number is carried out parallel operation and is got final product, and not only solved above-mentioned technical problem, and this device operates very convenient.
In the technique scheme, a plurality of adsorption tower groups that connect that are in parallel are meant: a plurality of adsorption tower groups are provided with concurrently, and the two ends of each adsorption tower group are connected with the nitrogen outlet total valve with the air inlet total valve respectively.
Between each adsorption tower group in the technique scheme all independently of one another, work in parallel.Specifically, when system nitrogen amount exceeds the load of an adsorption tower group, unstrpped gas is diverted in the adsorption tower group of a plurality of unlatchings, the adsorption tower group of each unlatching is all carried out work independently of one another simultaneously, and the nitrogen that makes of each adsorption tower group gathers the back by the discharging of nitrogen outlet total valve through the pipeline that is connected at last.
In running order adsorption tower group, a plurality of adsorption towers of forming this adsorption tower group hocket and adsorb and desorption.
As further improvement of the utility model, the volume of described adsorption tower is less than 0.025m
3Or interior diameter is less than 0.15m.According to " safe technology of pressure vessel supervision rules " regulation, diameter less than 0.15m or volume less than 0.025m
3The band pressure vessel be vessels not under pressure.The making of such adsorption tower can standardization, and the design of container, manufacturing cost just greatly reduce, and the production cycle also shortens relatively, and this class adsorption tower volume is very little, dead space in the adsorption tower is less on the one hand, so the adsorbent utilization rate improves, device produces nitrogen efficient and improves; On the other hand, the tolerance of each absorbing unit is less, can use flexible pipe to connect, and by-pass valve control also can adopt comparatively cheap magnetic valve directly to drive, and can reduce the cost of whole device.Moreover this class adsorption tower volume is very little, can arrange placement easily, for example can overlay sidewards on the base, also can which floor vertically divide stack, and also can be arranged in compactly in the closed box, and the volume of whole nitrogen-making device significantly reduces.When a certain group or several groups of adsorption tower groups break down, can be under the prerequisite that does not influence other adsorption tower group operate as normal, to change or adsorption tower group that maintenance is broken down, device is safeguarded convenient.
As another kind of improvement the of the present utility model, each adsorption tower group is alternately adsorbed by two and the adsorption tower of regeneration is formed.Owing to can adopt many group adsorption towers to solve the problem that system nitrogen amount is brought greatly, only need in each adsorption tower group so to adopt two adsorption tower alternations to get final product.
