Abstract
The utility model discloses nitrogen production equipment, and especially relates to a reverse pressing apparatus for pressure swing adsorption nitrogen production equipment. The reverse pressing apparatus comprises a pneumatic valve (1) arranged on a pipe for communicating a first absorption column (11) and a second absorption column (22) with a nitrogen buffer tank (2), the pipe for communicating the first absorption column (11) and the second absorption column (22) with the nitrogen buffer tank (2) is further provided with a one-way valve (3), and the one-way valve (3) is interconnected with the pneumatic valve (1) in parallel. The reverse pressing apparatus has the function of lowering the consumption of the compressed air, reducing the load on preceding stage purification equipment and a carbon molecular sieve, prolonging the service life of the purification equipment and the carbon molecular sieve and correspondingly improving the yield and the purity of the nitrogen under the same condition.
Description
Technical field
The utility model relates to a kind of equipment of making nitrogen, relates in particular to a kind of recoil pressure device for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE.
Background technology
The all pressures mode that is used for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE, and the equipment of making nitrogen is in the moment of all pressing and all pressing after finishing, need a large amount of pressurized air to boost, in the prior art, pressure in the adsorption tower only be rely on pressurized air and all press finish after in the nitrogen pot nitrogen return again to boost, cause inside to be boosted slow, in addition because the increase of pressurized air moment flow, strengthened the load of prime treating plant, cause compressed air purifying to be processed not exclusively, the load of carbonaceous molecular sieve also can increase simultaneously, so that the finished product nitrogen gas purity is unstable.
The utility model content
The purpose of this utility model is to provide a kind of recoil pressure device for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE, and the adsorption tower that solves existing THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE boosted slow, causes treating plant and the carbonaceous molecular sieve excessive problem that affects nitrogen gas purity of loading.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of recoil pressure device for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE, comprise the pneumavalve on the pipeline that is arranged on the first adsorption tower and the second adsorption tower connection nitrogen buffer tank, also be provided with check valve on the pipeline of the first adsorption tower and the second adsorption tower connection nitrogen buffer tank, described check valve and pneumavalve are parallel with one another.
For making the utility model play better technique effect:
Further technical scheme is that above-mentioned check valve place pipeline is provided with flow control valve.
The beneficial effect that adopts technique scheme to produce is: under equal bar, reduced compressed-air actuated consumption, alleviated simultaneously the load of prime treating plant and carbonaceous molecular sieve, in the work-ing life of having improved treating plant and carbonaceous molecular sieve, the output of nitrogen and purity are good to corresponding raising.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for an embodiment of recoil pressure device of THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the embodiment that the utility model is used for the recoil pressure device of THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE: a kind of recoil pressure device for THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE, comprise the pneumavalve 1 on the pipeline that is arranged on the first adsorption tower 11 and the second adsorption tower 22 connection nitrogen buffer tanks 2, also be provided with check valve 3 on the pipeline of the first adsorption tower 11 and the second adsorption tower 22 connection nitrogen buffer tanks 2, described check valve 3 is parallel with one another with pneumavalve 1.
Be used for an embodiment of the recoil pressure device of THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE according to the utility model, check valve 3 place pipelines are provided with flow control valve 4.
Principle of work of the present utility model is:
When needs are all pressed the first adsorption tower 11 and the second adsorption tower 22, can open simultaneously check valve 3, allow the nitrogen refluxs in the nitrogen buffer tank 2 enter,
For some time after all pressing end, if the pressure in the first adsorption tower 11 or the second adsorption tower 22 is also relatively low, nitrogen in the nitrogen buffer tank 2 can continue to continue to be back in the low adsorption tower of pressure by check valve 3 and pneumavalve 1, during pressure equilibrium in tower upon adsorption and the nitrogen buffer tank 2, closing one-way valve 3, normally nitrogen processed.
If the pipeline at check valve 3 places is provided with flow control valve 4, then can control nitrogen reflux speed in the nitrogen buffer tank 2 by flow control valve 4.
" embodiment " who speaks of in this manual, " another embodiment ", " embodiment ", " preferred embodiment " etc., the specific features, structure or the characteristics that refer in conjunction with this embodiment description are included among at least one embodiment of the application's generality description.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification sheets.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also drop in the scope of the present utility model.
Although with reference to a plurality of explanatory embodiment of the present utility model the utility model is described here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and embodiment will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes also will be obvious.
