Detailed implementation manners

[0028] An embodiment of the present invention provides a nitrogen purification nitrogen generation device, as Figures 1-7 shown, including an oxygen generation base 101, two nitrogen generation tanks 103 and an impurity filter 105. The two nitrogen generation tanks 103 are arranged on both sides of the top end of the oxygen generation base 101, and the positions of the two nitrogen generation tanks 103 on both sides are symmetrically arranged. The impurity filter 105 is arranged on the other side of the oxygen generation base 101. Moving handrails 116 are fixedly arranged on both end faces of the impurity filter 105. Air flow detectors 112 are installed on the top ends of the two nitrogen generation tanks 103. Product pipes 111 are communicated and arranged on the top ends of the two nitrogen generation tanks 103. A closed cover plate 107 is installed on the top end of the impurity filter 105, and the closed cover plate 107 plays a sealing role. Connecting pipes 109 are communicated and arranged on both sides of the top end of the closed cover plate 107, and a regulating air valve 108 is installed and connected to the outer end face of the connecting pipe 109.

[0029] It should be further noted that the regulating air valve 108 can control the on-off of the gas flow inside the connecting pipe 109.

[0030] Furthermore, a production air pipe 104 is communicated and arranged at the bottom of the impurity filter 105, and the production air pipe 104 is connected to the gas input pipe.

[0031] Furthermore, an impurity filtration chamber 120 is arranged inside the closed side plate 106, and a plurality of screens 121 are installed in the impurity filtration chamber 120, and the screens 121 are distributed in an array from top to bottom.

[0032] It should be further noted that the screen 121 on each side is made of a wire mesh and filled with polypropylene fibers or other filtering materials inside. It can form an electrostatic electret meltblown nonwoven fabric after electrostatic charging. Its fiber diameter is small, and it can effectively remove impurities such as dust and sand grains in the air.

[0033] Furthermore, the production air pipes 104 on both sides are communicated with the impurity filtering chamber 120, and the communication pipe 109 at the top is communicated with the impurity filtering chamber 120.

[0034] Furthermore, a closed side plate 106 is installed on the side of the impurity filter 105, and the closed side plate 106 plays an effect of sealing and protecting.

[0035] Furthermore, a nitrogen production chamber 117 is provided in the nitrogen production tank 103, and a number of nitrogen production plates 118 are installed in the nitrogen production chamber 117. A number of molecular sieve holes 119 are arranged in an annular array in the nitrogen production plate 118.

[0036] It should be further noted that the molecular sieve holes 119 are filled with a molecular sieve material for purifying nitrogen.

[0037] Furthermore, a processing pipe 115 is communicated at the bottom of the nitrogen production tank 103. The processing pipes 115 on both sides are communicated with the same input air pipe 102, and the input air pipe 102 extends outward to play an effect of connecting the inlet.

[0038] Furthermore, a switching pipe 110 is communicated above the side of the nitrogen production tank 103 on one side. The switching pipe 110 is communicated with the middle position of the input air pipe 102, and a switching valve 113 is provided at the connection position of the switching pipe 110 and the input air pipe 102.

[0039] It should be further noted that the switching valve 113 plays an effect of switching the pipeline.

[0040] When working, first drive the nitrogen generation tanks 103 on both sides and the impurity filter 105 to the working position, and connect the gas pipeline between the connecting pipeline 109 on one side and the pipeline interface of the input gas pipe 102 at the bottom to facilitate the subsequent gas input work. At this time, after connecting the production gas pipe 104 to the external processing gas pipeline, the gas to be processed is input into the impurity filtration chamber 120 through the production gas pipe 104, and during the process of outputting from the bottom upwards, through the array of sieve meshes 121, the gas to be processed is preliminarily filtered for impurities. Each side of the sieve mesh 121 is made of a metal wire mesh and filled with polypropylene fibers and other filtering materials inside, and can form an electrostatic electret melt-blown non-woven fabric after electrostatic charging. Its fiber diameter is small, and it can effectively remove impurities such as dust and sand grains in the air. When the preliminary filtration work is completed, at this time, the product gas is input into the input gas pipe 102 through the connecting pipeline 109, and through the processing pipeline 115 connected to the input gas pipe 102, the product gas is input into the nitrogen generation tank 103. At this time, the product gas flows through the nitrogen generation chamber 117 inside the nitrogen generation tank 103 from bottom to top, and through the nitrogen generation plates 118 on each side in the nitrogen generation chamber 117, further nitrogen purification work is carried out on the product to improve the efficiency of refined nitrogen production. Subsequently, the refined product nitrogen is output outward through the switching pipeline 110 at the top and passes through the airflow detector 112 on the side to detect the output rate of the product gas.

[0041] When it is necessary to further increase the concentration of the product nitrogen, at this time, the staff rotates the switching valve 113 at the connection of the input gas pipe 102 and the switching pipeline 110, and changes the connection mode between the input gas pipe 102 and the switching pipeline 110 by rotating the switching valve 113. At this time, the input gas pipe 102 is connected to one side of the processing pipeline 115, and the switching pipeline 110 is connected to the processing pipeline 115 on the other side, and the product pipeline 111 at the top of one side of the nitrogen generation tank 103 is closed. Subsequently, during the subsequent production process of the product gas, the product gas first enters one side of the nitrogen generation tank 103 through the processing pipeline 115 connected to the input gas pipe 102 on one side, and after preliminary nitrogen screening through the molecular sieve pores 119 in one side of the nitrogen generation tank 103, at this time, the product gas flows back to the input gas pipe 102 through the switching pipeline 110 and flows into the processing pipeline 115 connected to the other side, and enters the nitrogen generation tank 103 on the other side for further nitrogen refining work.

[0042] By switching the parallel and series connection modes of the nitrogen generation tanks 103, the speed of nitrogen refining work can be increased when in parallel, and the purity of refined nitrogen can be increased when in series.

[0043] It should be further noted that multiple nitrogen generation tanks 103 can be set up in series or in parallel to improve the efficiency of nitrogen refining work.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
