Description
Technical field
The utility model relates to a kind of energy-saving series connection varying-voltage adsorption nitrogen machine device of producing high-purity nitrogen, belong to a kind of air separation equipment and system.
Background technology
Traditional nitrogen gas preparing is by cleaning system (equipment), air reservoir, and nitrogen making machine, nitrogen storage tank, blowdown system, controller connects to form with pipeline.In producing the process of nitrogen, nitrogen be separated from air, as can be known along with the raising of nitrogen gas purity, nitrogen is empty than strengthening according to the carbon molecular sieve absorption property, air consumption increases, the carbon molecular sieve of required filling simultaneously will increase, thereby equipment volume also will strengthen, for the big cube of equipment of making nitrogen, because the work tower volume is big, many molecular sieves are not fully used, and make equipment not waste resource in the state operation of the best.Along with society in science and technology, the progress and development of aspects such as epoch, as electronics, heat treatment, food, chemical industry, nitrogen applications such as medicine, also more and more higher to the requirement of nitrogen gas purity, thereby, become the requirement that must improve the equipment of making nitrogen and technological process.Have only emphatically by the equipment of making nitrogen is transformed, and relevant nitrogen producing craft and flow process are transformed, could utilize Limited resources to greatest extent airborne oxygen to be removed, make higher degree nitrogen, just can help relevant industries and adapt to social development, could satisfy the demand of relevant industries nitrogen gas preparing and high-purity nitrogen.
Summary of the invention
The energy-saving series connection varying-voltage adsorption nitrogen machine device of drawbacks such as the purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of traditional single stage PSA nitrogen-making device energy consumption height that effectively overcomes is provided, and purity is low, and the life-span is short.
The purpose of this utility model is finished by following technical solution, it is mainly by cleaning system, air reservoir, nitrogen making machine, nitrogen storage tank, blowdown system, controller, connect to form with pipeline, described nitrogen making machine is composed in series by one-level nitrogen making machine and secondary nitrogen making machine, is serially connected with at least one general nitrogen storage tank between described one-level nitrogen making machine and the secondary nitrogen making machine.
Be serially connected with an air cushioning jar before the described one-level nitrogen making machine, and behind the secondary nitrogen making machine, be connected in series high purity nitrogen storage tank.
The waste gas that described secondary nitrogen making machine is discharged comprises that the nitrogen of regeneration nitrogen and defective emptying is recycled to air compressor after decompression.
The utility model adopts two-stage PSA device to produce high-purity nitrogen, has played certain energy-saving effect, has simple in structurely, uses reliable, safety, the organic efficiency height, and the purity of producing is low, characteristics such as long service life.
Description of drawings
Fig. 1 is a process structure schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model is mainly by cleaning system, air reservoir, nitrogen making machine, nitrogen storage tank, blowdown system, controller, connect to form with pipeline, described nitrogen making machine is composed in series by one-level nitrogen making machine 5 and secondary nitrogen making machine 7, is serially connected with at least one general nitrogen storage tank 6 between described one-level nitrogen making machine 5 and the secondary nitrogen making machine 7.Be serially connected with an air cushioning jar 4 before the described one-level nitrogen making machine 5, and at the high purity nitrogen storage tank 8 of secondary nitrogen making machine 7 back serial connections.The waste gas that described secondary nitrogen making machine 7 is discharged comprises that the nitrogen of regeneration nitrogen and defective emptying is recycled to air compressor after decompression.
Shown in the figure, the utility model integral body is by air cushioning jar 1, cleaning equipment 2, and one-level nitrogen making machine 5, air cushioning jar 4, secondary nitrogen making machine 7, blowdown system 9, controller connects to form with pipeline.It is the technology that adopts the series connection of two-stage PAS (transformation absorption) device, gas carries out oil removing through cleaning equipment 3 and dewaters and enter first order PSA device, be one-level nitrogen making machine output purity nitrogen (90-95% purity), to nitrogen buffer tank, be that general nitrogen storage tank 6 cushions, then low-purity nitrogen gas is transported to second level PSA device, be that secondary nitrogen making machine 7 carries out the secondary purification, nitrogen gas purity further is promoted to 99.9-99.999%, send into high purity nitrogen storage tank 8, delivering to air compressor inlet after the waste gas that second level PSA nitrogen gas preparing is discharged (nitrogen of regeneration nitrogen and the defective emptying) decompression carries out recycling, further improved the gas purity of first order PSA nitrogen device portal, thereby improve the organic efficiency of front and back stages PSA nitrogen device, effectively overcome traditional single stage PSA nitrogen-making device energy consumption height, purity is low, and the drawback that the life-span is short is a kind of high-efficiency and energy-saving type PSA nitrogen-making device.Its technological process is seen shown in Figure 1.
The utility model is because by two-stage PSA nitrogen-making device, the first order PSA device that makes moves in low load behavior, make the required nitrogen gas purity requirement of second level PSA, second level PSA nitrogen-making device can prolong adsorption time simultaneously, utilize the gas of its regeneration to carry out recycling, prolong the service life of equipment in the time of the continuous output high-purity nitrogen of the equipment that guaranteed so again, played the purpose of energy savings.The utility model is further perfect nitrogen gas preparing and technological process have further promoted the nitrogen gas purity technological layer again, for producing high-purity nitrogen, satisfy high-purity nitrogen and answer the demand of field to high-purity nitrogen and nitrogen gas preparing, and technical conditions are provided.
