DETAILED DESCRIPTION

[0033] The embodiment of the present invention provides an intelligent molecular sieve pressure swing adsorption oxygen production system, such as Figure 1-10As shown, it includes an air compressor 101, an air tank 109, an air purification system 107 and an adsorption tower 111. Two air tanks 109 are arranged at one end of the air compressor 101 and stand side by side. An air purification system 107 is arranged between the air tanks 109 on both sides. A plurality of adsorption towers 111 are arranged on one side of the air tank 109. A plurality of brackets 110 are fixedly arranged at the bottom of the adsorption tower 111 to play a stable support effect. An output duct 108 is connected to the top of the air tank 109 close to the air compressor 101. The output duct 108 is connected to the input pipe of the air purification system 107. The bottom of the air tank 109 on the other side is connected to the output pipe mouth of the air purification system 107. An oxygen production chamber 127 is arranged in the plurality of adsorption towers 111. A spiral spiral guide plate 129 is arranged in the oxygen production chamber 127. A communication regulator 122 is arranged between two adjacent adsorption towers 111, and the communication regulator 122 is used to switch the series and parallel connection between the adsorption towers 111.

[0034] It should be further explained that the air purification system 107 is composed of a refrigeration dryer, a heatless adsorption dryer and a precision filter for removing oil and water. This combined device removes oil, water and impurities from the air more thoroughly.

[0035] like Figure 4 As shown, the air compressor 101 also includes a plurality of support rods 102 fixed at the bottom, and the support rods 102 play a role of stable support. A plurality of air intake devices 103 are arranged at the top of the air compressor 101, and the air intake devices 103 are distributed in an array. A compressed air output pipe 119 is connected to one end of the air compressor 101, and a connecting input pipe 117 is connected to the bottom of the air tank 109. The connecting input pipe 117 is connected to the compressed air output pipe 119, and an automatic drainer 116 is fixedly installed at the bottom of the air tank 109.

[0036] It is worth noting that the automatic drain 116 can play the function of automatic drainage, which can prevent water from accumulating inside the air tank 109 and causing the working efficiency of the air tank 109 to decrease.

[0037] Furthermore, a connecting valve port 113 is provided at the top of the adsorption tower 111 on each side, a flow meter 112 is installed on one side of the connecting valve port 113, a horizontal connecting pipe 124 is provided between the connecting valve ports 113 on adjacent sides, and an input air pipe 120 is provided between the bottoms of the adsorption towers 111 on adjacent sides.

[0038] It should be further explained that the flow meter 112 can detect various parameters of the airflow flowing out of the communication valve port 113 .

[0039] Furthermore, regulating connecting pipes 125 are respectively connected to the upper and lower sides of the connecting regulator 122. The upper regulating connecting pipe 125 is connected to the cross-frame connecting pipe 124, and the lower regulating connecting pipe 125 is connected to the input air pipe 120. Control regulating valves 121 are respectively installed at the connections between the regulating connecting pipes 125 on both sides and the cross-frame connecting pipe 124 and the input air pipe 120.

[0040] It should be further explained that the control regulating valve 121 can adjust the connection state of each pipeline by controlling the rotation.

[0041] Furthermore, an oxygen production output pipeline 123 is provided on the upper side of the connecting regulator 122, and an inlet at the lower side of the connecting regulator 122 is connected to the air tank 109. A concentration detector 126 is installed on the side of the adsorption tower 111, and another gas output pipeline 137 is provided at the bottom of the adsorption tower 111 on one side, and the gas output pipeline 137 is connected to the oxygen production output pipeline 123.

[0042] It should be further explained that the concentration detector 126 is capable of detecting the concentration of gas components in the adsorption tower 111 and providing information feedback.

[0043] Furthermore, a plurality of molecular sieve devices 128 arranged in a matrix are fixedly disposed on the surface of the spiral guide plate 129 .

[0044] It should be further explained that, according to different process requirements, the molecular sieve device 128 can be filled with different types to adsorb nitrogen or other impurity gases in the air, thereby enriching oxygen.

[0045] like Figure 8 The second embodiment of the present scheme is shown, which is different from the first embodiment in that a plurality of molecular sieve devices 128 are installed in an array and distributed on the inner wall of the oxygen production chamber 127, and have the effect of increasing the contact area between the vortex air and the molecular sieve device 128.

[0046] like Fig. 9 and Fig.10 As shown, it is the third embodiment of the present scheme, which is different from the above two embodiments in that a spiral spiral guide plate 129 is fixedly provided on the inner wall of the oxygen production chamber 127, a cylindrical support connection 130 is fixedly provided on the top of the oxygen production chamber 127, and a spiral matching threaded plate 136 is fixedly provided on the outer end surface of the support connection 130. The matching threaded plate 136 corresponds to the arc of the spiral guide plate 129, and a spiral spiral groove 132 is formed between the spiral guide plate 129 and the matching threaded plate 136.

[0047] Furthermore, lifting controllers 133 are fixedly provided on the upper sides of the outer end surfaces of the adsorption tower 111, and the lifting controllers 133 on both sides are symmetrically arranged. Support guide rods 135 are connected to both sides of the top of the oxygen production chamber 127, and lifting guide plates 134 that can be lifted and lowered are provided in the support guide rods 135. Support guide rods 135 are fixedly provided on the lower end surfaces of the lifting guide plates 134 on both sides, and a spiral lifting spiral plate 131 is installed at the lower end of the support guide rods 135, and a plurality of molecular sieve devices 128 are installed on the upper and lower sides of the lifting spiral plate 131.

[0048] It should be further explained that the lifting spiral plate 131 is lifted and moved in the spiral groove 132, and a pneumatic device is provided in the lifting controller 133, which can drive the lifting guide plate 134 to lift and move, and then drive the lifting spiral plate 131 to lift and move through the support guide rod 135.

[0049] It is worth further explaining that when the lifting controller 133 is started, the lifting guide plate 134 can be driven to lift and move through the internal propulsion cylinder, and then the support guide rod 135 can be driven to lift and move through the transmission of the lifting guide plate 134. The support guide rod 135 can drive the lifting spiral plate 131 to lift and move as a whole. At this time, when the lifting spiral plate 131 moves to the upper limit position, the lifting spiral plate 131 moves to close the spiral groove 132, and the lifting spiral plate 131 is combined with the spiral guide plate 129 and the matching threaded plate 136 to form a single connected spiral pipe. At this time, the airflow flows from the inside. When the lifting spiral plate 131 is driven to move to the lower limit position, the lifting spiral plate 131 is located between the upper and lower layers of threads of the spiral guide plate 129. At this time, through the cooperation between the lifting spiral plate 131, the spiral guide plate 129 and the matching threaded plate 136, a more spiral airflow guiding channel can be formed, and the airflow and nitrogen adsorption efficiency can be further expanded, and the contact area between the airflow and the molecular sieve device 128 can be expanded.

[0050] It should be further explained that a gas storage tank is provided on one side of the communication regulator 122 and is connected to the oxygen production output pipeline 123, so as to store the oxygen produced by the oxygen production system.

[0051] When working, firstly, the air compressor 101, the air tank 109, the air purification system 107 and the adsorption tower 111 are connected in sequence according to the requirements of the oxygen production system, and the oxygen tank is connected to the oxygen production output pipeline 123. At this time, the air compressor 101 compresses the air through the air inlet 103 at the top to provide an air source for the whole system and provide a stable pressure for the subsequent molecular sieve pressure swing adsorption.

[0052] The compressed air then drawn in is output through the compressed air output pipe 119, and is output to the air tank 109 on one side through the connecting input pipe 117. The air drawn in is stabilized and filtered through the air tank 109 on one side, and the moisture in the air is filtered. At the same time, the automatic drainer 116 can play the function of automatic drainage, which can prevent water from accumulating inside the air tank 109 and causing the working efficiency of the air tank 109 to decrease. The air after preliminary filtration is then output to the air purification system 107 through the output duct 108. The air purification system 107 is composed of a refrigeration dryer, a heatless adsorption dryer and a precision filter for oil and water removal. The combined device can filter the oil, water and impurities in the air flowing through it more thoroughly.

[0053] Subsequently, the compressed air that has undergone secondary filtration is connected to the air tank 109 on the other side through the air purification system 107, and the compressed air is output, and the air prevention effect is achieved through the air tank 109 on the other side. If there are still impurities and moisture remaining in the compressed air that has undergone secondary filtration, the air tank 109 on the other side can be used to further remove them. At the same time, if the moisture in the air tank 109 on the front side is not discharged in time through the automatic drainer 116 due to long-term work, the air tank 109 on the other side can play a preventive role, thereby improving the efficiency of subsequent pressure swing adsorption oxygen production.

[0054] Then, the processed compressed air is input into the connecting regulator 122 through the output duct 108 at the top of the air tank 109 on the other side, and the connectivity of each duct is connected through the connecting regulator 122. At this time, the compressed air is output downward through the regulating connecting pipe 125 on the lower side and input into the adsorption towers 111 on both sides through the input air pipe 120, and each adsorption tower is filled with a specific type of molecular sieve material to adsorb nitrogen and other impurity gases in the air, thereby enriching oxygen. Then, after a certain concentration of oxygen is produced, it is output through the connecting valve port 113, and after being summarized through the cross-frame connecting pipe 124 and input through the upper regulating connecting pipe 125, the produced oxygen is output to the gas storage tank, that is, the oxygen tank, through the oxygen production output pipe 123 for storage.

[0055] At the same time, when the connecting valve port 113 is outputting oxygen, the flow rate of the airflow passing through the connecting valve port 113 is first monitored by the flow meter 112, and the oxygen concentration in the adsorption tower 111 is detected by the concentration detector 126. If it is detected that the oxygen concentration cannot meet the production standard, the control regulating valves 121 on each side are switched, and the connecting layout of the pipeline is adjusted. At this time, the compressed oxygen is first input into the input air pipe 120 on one side through the regulating connecting pipeline 125 on the lower side, and is unilaterally input into the adsorption tower 111 on one side for pressure swing adsorption oxygen production. At this time, The horizontal connecting pipe 124 at the top is connected to input the oxygen produced by pressure swing adsorption after the initial reaction into the adsorption tower 111 on the other side for reaction, and then the produced oxygen is input back into the oxygen production output pipe 123 through the bottom gas output pipe 137, and then the produced oxygen is output to the gas storage tank through the oxygen production output pipe 123, that is, the oxygen tank for storage. When the adsorption towers 111 are connected in parallel, the efficiency of producing oxygen by pressure swing adsorption can be improved. When the adsorption towers 111 are connected in series, the accuracy and purity of oxygen produced by pressure swing adsorption can be improved, thereby realizing the production of oxygen with different purities.

[0056] When the first embodiment is adopted, the compressed air is input into the oxygen production chamber 127 through the air input pipe 120, and is guided by the spiral guide plate 129 so that the input compressed air is output in the form of spiral rotation. In this process, the specific molecular sieve material filled in the molecular sieve device 128 installed on the surface of the spiral guide plate 129 is used to adsorb nitrogen and other impurities in the air, thereby enriching oxygen and improving the concentration of the output oxygen.

[0057] When the second embodiment is adopted, the compressed air is input into the oxygen production chamber 127 through the air input pipe 120, and is guided by the spiral guide plate 129, so that the input compressed air is output in the form of spiral rotation. In this process, the specific molecular sieve material filled in the molecular sieve device 128 installed on the surface of the oxygen production chamber 127 is used to adsorb nitrogen and other impurities in the air, thereby enriching oxygen and increasing the concentration of the output oxygen. At this time, due to the molecular sieve filled with the inner wall of the oxygen production chamber 127, it is only necessary to replace the adsorption tower 111 filled with different materials according to different processes to carry out oxygen production work, which can adapt to the production of processes with different oxygen concentrations.

[0058] When the third embodiment is adopted, the compressed air is input into the oxygen production chamber 127 through the air input pipe 120 and guided by the spiral guide plate 129 and the lifting spiral plate 131, and the input compressed air is output in the form of spiral rotation. At the same time, in this process, the air flow is guided and adjusted through the connecting valve port 113. When the lifting controller 133 is started, the lifting guide plate 134 can be driven to move up and down through the internal propulsion cylinder, and then the support guide rod 135 can be driven to move up and down through the lifting guide plate 134. The support guide rod 135 can drive the lifting spiral plate 131 to move up and down as a whole. At this time, when the lifting spiral plate 131 moves to the upper limit position, the lifting spiral plate 131 moves to close the spiral groove 132, and through the lifting spiral Plate 131 is combined with the spiral guide plate 129 and the matching threaded plate 136 to form a single connected spiral pipe. At this time, the air flow flows from the inside. When the lifting spiral plate 131 is driven to move to the lower limit position, the lifting spiral plate 131 is located between the upper and lower layers of threads of the spiral guide plate 129. At this time, through the cooperation between the lifting spiral plate 131, the spiral guide plate 129 and the matching threaded plate 136, a more spiral airflow guiding channel can be formed, and the airflow and nitrogen adsorption efficiency can be further expanded, and the contact area between the airflow and the molecular sieve device 128 can be expanded. At this time, the specific molecular sieve material filled on the surface of the lifting spiral plate 131 and the change in the guidance of the airflow can achieve pressure swing adsorption, thereby enriching oxygen and increasing the concentration of output oxygen.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
