Description
Technical field
The present invention relates to equipment of making nitrogen manufacturing technology field, especially a kind of air that utilizes is by the equipment of pressure-variable adsorption mode nitrogen.
Background technology
Existing THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE generally comprises the pressurized air pre-processing device connected by pipeline, is connected to the adsorption tower after this equipment, and adsorption tower is connected to nitrogen storage tank, and nitrogen storage tank is connected to terminal user.Adsorption tower generally comprises and is provided with two adsorption towers, first adsorption tower and the second adsorption tower, in parallel by multichannel pipeline between them, every road pipeline is in series with two control valves, also be provided with a pressure release valve, control valve is opened in turn, to take turns control valve on this road pipeline of mobile equilibrium for node is to the pressure equilibrium of one of them adsorption tower.The setting of this two adsorption towers and mode of connection, pressurized air can be made in first adsorption tower to be predominantly absorbed oxygen, pressurized air is afterwards cyclic absorption in two adsorption towers, nitrogen content can be improved, and serve certain equalized pressure and the effect of temperature, but two adsorption towers connect so simply, all press former so need reducing valve exit decompression, and air compressor machine also will cover the dividing potential drop of adsorption tower when pressurising, can not automatically dividing potential drop flexibly, waste again compressed-air actuated resource.
Summary of the invention
Problem to be solved by this invention is to provide a kind of equipment of making nitrogen, to solve existing THE PRESSURE SWING ADSORPTION NITROGEN GENERATING DEVICE owing to all pressing the bad problem causing the pressurized air wasting of resources.
In order to solve the problem, the technical solution used in the present invention is: this equipment of making nitrogen includes the pressurized air pre-processing device be connected with control valve by pipeline, nitrogen storage tank, and the first adsorption tower be located between the two and the second adsorption tower, be parallel with one between described first adsorption tower and described second adsorption tower and compensate air bag, the position that described compensation balloon ends connects described first adsorption tower is respectively provided with a check valve, two the check valve directions connecting described first adsorption tower are contrary, the position that described compensation balloon ends connects described second adsorption tower is respectively provided with a check valve, two the check valve directions connecting described second adsorption tower are contrary, contrary with two check valve directions that described first adsorption tower and described second adsorption tower connect on the same end of described compensation air bag.
In above-mentioned technical scheme, more specifically scheme can also be: described compensation air bag is that rubber compensates air bag.
Further: described compensation air bag is that polyvinyl chloride mantle compensates air bag.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This equipment of making nitrogen adopts and arrange buffer compensation air bag between two adsorption tower, and compensates the connect form of a check valve of air bag and realize all pressing, and controls multiple control valve, save manpower and equipment cost without the need to artificial control or by control panel; Use air bag as buffer compensation device, flexibility can being realized and all press, reducing pressure without the need to being vented by reducing valve, save pressurized air resource.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing enforcement, the invention will be further described:
The equipment of making nitrogen as shown in Figure 1, include the pressurized air pre-processing device be connected with control valve by pipeline, pressurized air pre-processing device includes air compressor machine 1, air compressor machine 1 connects gas-holder by pipeline, gas-holder connects water-and-oil separator 2, water-and-oil separator 2 is connected an air filter 3 by pipeline with control valve 5, air filter 3 connects freeze drier 4 by pipeline, freeze drier 4 is connected an air filter 3 by pipeline with control valve 5, and air filter 3 connects adsorption tower by pipeline.Adsorption tower has two, and the first adsorption tower 6 and the second adsorption tower 9, air filter 3 connects the first adsorption tower 6.Be parallel with one between first adsorption tower 6 and the second adsorption tower 9 and compensate air bag 7, the position that compensation balloon ends connects the first adsorption tower 6 is respectively provided with a check valve 8, and two check valve 8 directions connecting the first adsorption tower 6 are contrary; The position that compensation air bag 7 two ends connect the second adsorption tower 9 is respectively provided with a check valve 8, and two check valve 8 directions connecting the second adsorption tower 9 are contrary, compensates air bag 7 with contrary with two check valve 8 directions that the first adsorption tower 6 and the second adsorption tower 9 connect on one end.The pressure process that pressurized air is predominantly absorbed oxygen at the first adsorption tower 6 becomes large, the second adsorption tower 9 is progressed into through compensating air bag 7 by check valve 8, pressurized air is from the second adsorption tower 9 to the first adsorption tower 6 recirculation, compensate the effect of the existing buffering of air bag, also the effect of the compensatory pressure when the second adsorption tower 9 pressure is too small is had, the size of pressure also without the need to manual control, also without the need to considering the control of all pressing the time in two adsorption towers.The use of check valve, keeps whole compressed-air actuated working cycle uninterruptedly and not reflux again.Here compensation air bag is that the extremely strong polyvinyl chloride mantle of intensity and toughness compensates air bag.The outlet pipe of the second adsorption tower is connected to nitrogen storage tank 10, and nitrogen storage gas tank 10 is connected to terminal user.
In other embodiments, according to different operating modes, compensating air bag can also be the compensation air bag that rubber is made.
