[0011] As a further improvement, the heating frame comprises a horizontal shaft section arranged on the circulating feeding structure, a plurality of V-shaped contact sections are connected to the outer circumferential surface of the horizontal shaft section, and the V-shaped contact sections are communicated with the horizontal shaft section.
[0012] As a further improvement, the material blocking slope is a plurality of circular protrusions arranged at intervals, and the universal nitrogen in the convex part reacts with the catalyst in the material blocking slope at the position of the V-shaped contact section.
[0013] As a further improvement, the one-way hole comprises a through hole communicating the inner and outer sides of the first fixed clamp base, and a one-way valve plate is arranged on the side of the through hole facing the inside of the first fixed clamp base.
[0014] As a further improvement, the catalyst circulating pipe comprises a side-bent pipe inserted into the side of the second fixed clamp base, and a lower guide pipe is arranged on the outer side of the side-bent pipe.
[0015] As a further improvement, the feeding tray is arranged above the second fixed clamp base, and the universal nitrogen entering through the one-way hole in the circular ring part directly reacts with the catalyst in the feeding tray under the heating of the heating frame.
[0016] As a further improvement, the material holding cavity comprises a plurality of conical holes arranged on the feeding tray, an elastic bag is arranged in the inside of the conical hole, and a spring fixedly connected with the second fixed clamp base is arranged at the bottom of the elastic bag.
[0017] As a further improvement, the rotating assembly comprises a set of driving members connected to the outside of the heating frame, one side of the driving member is provided with a set of outer sealing sleeves connected to the end of the heating frame, the inner side of the outer sealing sleeve is provided with a heat medium outlet pipe communicated with the heating frame.
[0018] As a further improvement, the driving member comprises a fixed gear connected to the outside of the heating frame, the upper side of the fixed gear is engaged with a movable gear, and the movable gear is driven by a motor.
[0019] The beneficial effects of the present application are as follows:
[0020] The existing nitrogen purification directly heats the common nitrogen in the equipment with the catalyst under high temperature conditions, but the heat end of this step is not always at the same place as the catalyst, which leads to incomplete reaction of the common nitrogen with the catalyst, and further leads to the oxygen in the common nitrogen cannot be completely removed, therefore, the present application adds a middle heating structure, which forms a space for loading the catalyst by the first and second fixed clamping seats, and sets a heating frame directly between the first and second fixed clamping seats, which can evenly distribute the catalyst between the first and second fixed clamping seats, and can evenly contact with the catalyst when the nitrogen gas is input from the first fixed clamping seat, at the same time, since the catalyst is directly scattered on the outside of the heating frame, it is located at the optimal temperature position when the catalyst contacts with the nitrogen gas, so that the complete reaction of the nitrogen gas with the catalyst can be realized, and the oxygen in the nitrogen gas completely forms carbon dioxide with the carbon in the catalyst, thereby improving the purity of the nitrogen gas, and the purity of the nitrogen gas is ≥99.999%.
[0021] The first and second fixed clamping seats are not regular shapes, in order to adapt to the shape of the heating frame and improve the contact area of the heating frame with the nitrogen gas as much as possible, the first fixed clamping seat of the present application comprises a circular ring part and an outer convex part, so that there are relatively uniform planes to accommodate the catalyst, and there are inclined surfaces to contact the nitrogen gas in advance, and the catalyst can be held on the inner bottom of the second fixed clamping seat, thereby improving the efficiency and completeness of the overall reaction.
[0022] The traditional heating structure is usually a spring tube structure or a columnar structure, but in fact such arrangement is not only not conducive to contact with the gas, but also not conducive to the catalyst attached thereto, therefore, the heating frame of the present application comprises a horizontal shaft section to ensure the heating of the horizontal section and the overall heat medium circulation, and a V-shaped contact section is also provided, which is annularly arranged on the horizontal shaft section, which not only increases the contact with the nitrogen gas on multiple surfaces, but also the V-shaped contact section can serve as a catalyst bearing surface, so that the catalyst falls on the V-shaped contact section after being blown in, and has more contact possibilities with the nitrogen gas.
[0023] But relatively, the whole V-shaped contact section is relatively smooth, and the catalyst can not stay on the V-shaped contact section, therefore, the material blocking slope of the utility model is a plurality of circular protrusions, forming a small partition, so that the catalyst stays between two protrusions, thereby improving the reaction efficiency of the position.
[0024] Since the direction of vacuumizing is the same as the direction of nitrogen entering, the structure of setting a one-way valve is not feasible, but since the vacuumizing is in the form of negative pressure, compared with the pressure of nitrogen entering the top, the influence on the one-way structure is not so great, therefore, the utility model opens a one-way valve plate on the one-way hole, when the nitrogen enters the positive pressure, the one-way valve plate will be flushed open, allowing the gas to flow normally, and when the catalyst is extracted under negative pressure, although the one-way valve plate will be partially affected, but it will not be completely opened, even if it is partially opened, it can also weaken the gap with the outside, thereby not affecting the extraction of the catalyst.
[0025] The material holding cavity is used to contain the catalyst, but if it is directly set as a solid structure, it is difficult to extract the catalyst particles inside, therefore, the utility model sets an elastic bag and a spring in the inside of the material holding cavity, which can press the elastic bag and the spring when the catalyst enters, forming temporary storage, and can also deform in time when negative pressure is generated, so as to timely discharge the catalyst and complete the circulation of new catalyst.
[0026] In order to make the used catalyst on the V-shaped contact section completely fall off, the utility model sets a driving member on the outside of the heating frame, which drives the whole heating frame to rotate, and seals the cooperation gap between the heating frame and the heat medium discharge pipe through the sealing sleeve, avoiding the leakage of heat medium, while not affecting the rotation of the heating frame driven by the driving member.
[0027] During the use of the catalyst, the carbon content contained therein will gradually decrease after being used for a period of time, until it does not contain carbon, so the catalyst needs to be replaced after a period of use, but since the catalyst has been arranged between the first and second fixed clamping seats, the replacement of the catalyst is relatively difficult, therefore, the utility model sets a circulating material guiding structure on the basis of the middle heating structure, which arranges the catalyst irregularly on the inside of the material catching disc, the material holding cavity, the material blocking slope and the second fixed clamping seat, and after use, the catalyst on the heating frame is flung downward by the rotating assembly, so that the catalyst falls completely to the material catching disc, the material holding cavity and the second fixed clamping seat, and then all the catalyst is extracted by vacuumizing the whole tower body through the catalyst circulating pipe, and the new catalyst is punched in through the catalyst supply pipeline, forming the replacement of the catalyst.

[0041] In the process of nitrogen purification, the nitrogen (purity ≥ 99.9%) prepared by the nitrogen preparation system is directly heated to about 300℃ in the middle heating structure in the inside of the deoxidizing tower, and under the catalytic action of the catalyst, the trace oxygen in the nitrogen reacts with carbon to generate carbon dioxide, which is cooled to a lower temperature by the cooler 30 and then treated by the specially-made first purification tower 40 and the second purification tower 50 (molecular sieves with strong carbon dioxide adsorption capacity are used to shorten the running switching period of the adsorption type dryer and increase the amount of adsorbed carbon dioxide under the premise of ensuring the nitrogen consumption), so as to remove the carbon dioxide and trace water in it, and high-purity clean nitrogen with a purity of ≥ 99.999% is obtained through the purity analysis device.
[0042] The existing nitrogen purification directly heats the common nitrogen with the catalyst in the equipment under high temperature conditions, but the heat end of the step is not always at the same place as the catalyst, so that the reaction of the common nitrogen with the catalyst is not complete enough, thereby the oxygen in the common nitrogen cannot be completely removed clean, therefore, the utility model discloses a middle heating structure is additionally arranged, a space for loading the catalyst is formed through the first fixed clamp seat 61 and the second fixed clamp seat 62, and the heating frame 63 is directly arranged between the first fixed clamp seat 61 and the second fixed clamp seat 62, on the one hand, the catalyst can be uniformly distributed between the first fixed clamp seat 61 and the second fixed clamp seat 62, and can uniformly contact the catalyst when nitrogen is input from the first fixed clamp seat 61, at the same time, since the catalyst is directly scattered on the outside of the heating frame 63, the catalyst is just located at the position of the optimum temperature when contacting the nitrogen, so that the complete reaction of the nitrogen and the catalyst can be realized, the oxygen in the nitrogen completely forms carbon dioxide with the carbon in the catalyst in this stage, and then the purity of the nitrogen is improved, and the purity of the nitrogen is greater than or equal to 99.999%.
[0043] The first fixed clamp seat 61 and the second fixed clamp seat 62 are not a regular shape, in order to adapt to the shape of the heating frame 63, the contact area of the heating frame 63 and the nitrogen is as large as possible, the first fixed clamp seat 61 of the embodiment comprises a circular ring part 611 fixedly connected with the inner wall of the first deoxidizing tower 10, the inner side of the circular ring part 611 is connected with an arched outward convex part 612, and the outer sides of the circular ring part 611 and the outward convex part 612 are provided with one-way holes 64, wherein the first fixed clamp seat 61 comprises the circular ring part 611 and the outward convex part 612, so that a relatively uniform plane can be obtained, the catalyst can be accommodated, and the inclined surface can be used to contact the nitrogen in advance, and the catalyst can be held on the inner side bottom of the second fixed clamp seat 62, thereby improving the efficiency and completeness of the overall reaction.
[0044] The traditional heating structure is often a spring tube structure or a columnar structure, but in fact, such a setting is not only not conducive to contacting the gas, but also not conducive to the catalyst being attached thereto, therefore, the heating frame 63 of the embodiment comprises a horizontal shaft section 631 arranged on the circulating supply structure, a plurality of V-shaped contact sections 632 are connected to the outer peripheral surface of the horizontal shaft section 631, and the V-shaped contact sections 632 are communicated with the horizontal shaft section 631, wherein the heating frame 63 comprises the horizontal shaft section 631 to ensure the heating of the horizontal section and the circulation of the overall heat medium, and the V-shaped contact sections 632 are also arranged in a ring shape on the horizontal shaft section 631, which not only increases the contact with the nitrogen on multiple surfaces, but also enables the V-shaped contact sections 632 to act as a catalyst bearing surface, so that the catalyst can have more contact possibilities with the nitrogen after being blown into the V-shaped contact sections 632, in the embodiment, the V-shaped contact sections 632 are provided with six groups, and can also be provided with four groups or five groups.
[0045] But relatively, the whole V-shaped contact section 632 is relatively smooth, and the catalyst may not stay on the V-shaped contact section 632, so in this embodiment, the blocking slope 83 is a plurality of circular protrusions, the blocking slope 83 is arranged at intervals, and the nitrogen in the outer convex part 612 reacts with the catalyst in the position of the V-shaped contact section 632 and the blocking slope 83, forming a small partition between the blocking slope 83, so that the catalyst stays between two protrusions, thereby improving the reaction efficiency of the position, and in other embodiments, the blocking slope 83 can also be a concave structure, which can be directly used to carry the catalyst particles and directly react in the inner part.
[0046] Since the direction of vacuumizing is the same as the direction of nitrogen entering, the structure of setting a one-way valve is not feasible, but since vacuumizing is in the form of negative pressure, compared with the pressure of nitrogen entering the top, the influence on the one-way structure is not so great, so the one-way hole 64 of this embodiment includes a through hole communicating the inside and outside of the first fixed clamp seat 61, and the side of the through hole facing the inside of the first fixed clamp seat 61 is provided with a one-way valve plate, by opening the one-way valve plate on the one-way hole 64, when the nitrogen enters the positive pressure, the one-way valve plate will be washed away, allowing the gas to flow normally, and when the catalyst is extracted by negative pressure, although the one-way valve plate will be partially affected, but it will not be completely opened, even if it is opened, it can also weaken the gap with the outside, so as not to affect the extraction of the catalyst.
[0047] The setting position of the catalyst circulation pipe 74 is not like the catalyst supply pipe 73, which is arranged at the upper end, but is arranged at the lower end, and wants to turn a certain angle, specifically, the catalyst circulation pipe 74 includes a side bending pipe 741 inserted into the side of the second fixed clamp seat 62, and the outer side of the side bending pipe 741 is provided with a lower guide pipe 742, which is discharged outside through the lower guide pipe 742 after reversing through the side bending pipe 741.
[0048] During the use of the catalyst, the carbon content contained therein will gradually decrease after being used for a period of time until no carbon is contained, so the catalyst needs to be replaced after being used for a period of time, but since the catalyst has been arranged between the first fixed clamping seat 61 and the second fixed clamping seat 62, the replacement of the catalyst is relatively difficult, therefore, the utility model sets the circulating material guiding structure on the basis of the middle heating structure, when the catalyst is introduced into the first fixed clamping seat 61 and the second fixed clamping seat 62, it will be irregularly arranged on the inside of the material pocket 81, the material containing cavity 82, the material blocking slope 83 and the second fixed clamping seat 62, and after being used, the catalyst on the heating frame 63 is shaken down by rotating the rotating assembly 84, so that the catalyst falls down to the material pocket 81, the material containing cavity 82 and the second fixed clamping seat 62, and then the catalyst is pumped out by vacuumizing the whole tower body through the catalyst circulating pipe 74, and then new catalyst is pumped in through the catalyst supply pipeline 73, so that the replacement of the catalyst is formed.
[0049] Since the whole heating frame 63 needs to be rotated, the material pocket 81 cannot be directly arranged on the heating frame 63, therefore, the material pocket 81 of the embodiment is located above the second fixed clamping seat 62, and the nitrogen directly introduced into the material pocket 81 through the one-way hole 64 on the ring part 611 reacts with the catalyst in the material pocket 81 under the heating of the heating frame 63.
[0050] The material containing cavity 82 is used for containing the catalyst, but if it is directly arranged in a fixed structure, it is relatively difficult to pump out the catalyst particles in the inside, therefore, the material containing cavity 82 of the embodiment comprises a plurality of conical holes 821 arranged on the material pocket 81, the inside of the conical hole 821 is provided with an elastic bag 822, and the bottom of the elastic bag 822 is provided with a spring 823 fixedly connected to the second fixed clamping seat 62, by arranging the elastic bag 822 and the spring 823 in the inside of the material containing cavity 82, the elastic bag 822 and the spring 823 can be pressed when the catalyst enters, so that temporary storage is formed, and the elastic bag 822 and the spring 823 can be deformed in time when negative pressure suction is generated, so that the catalyst is discharged in time and the circulation of the new catalyst is completed.
[0051] In order to completely drop off the used catalyst on the V-shaped contact section 632, the utility model sets a driving member 841 on the outside of the heating frame 63, the rotating assembly 84 comprises a set of driving members 841 connected to the outside of the heating frame 63, one side of the driving member 841 is provided with an outer sealing sleeve 842 connected to the end of the heating frame 63, the inside of the outer sealing sleeve 842 is provided with a heat medium discharging pipe 843 in communication with the heating frame 63, the whole heating frame 63 is driven to rotate by the driving member 841, and the cooperation gap between the heating frame 63 and the heat medium discharging pipe 843 is sealed by the sealing sleeve 842, so that the heat medium is prevented from leaking, and the driving member 841 drives the heating frame 63 to rotate without being affected.
[0052] The driving member 841 of the embodiment comprises a fixed gear 8411 fixed outside the heating frame 63, an upper portion of the fixed gear 8411 is engaged with a movable gear 8412, the movable gear 8412 is driven by a motor 8413, the movable gear 8412 is driven to rotate by the external motor 8413, and then the fixed gear 8411 and the heating frame 63 connected with the fixed gear 8411 are rotated, so that the effect of better material replacement is achieved.
[0053] The above only describes the preferred embodiments of the present application and is not intended to limit the present application.
