Description

Technical Field

[0001] The present invention relates to the technical field of oxygen production equipment, and in particular to an intelligent and efficient integrated oxygen production equipment. Background Art

[0002] Oxygen production equipment is a device that can extract high-concentration oxygen from the air. It is widely used in many fields such as medical care, industry, environmental protection, and plateau areas. Its types include household oxygen generators, medical oxygen generators, industrial oxygen generators, etc. Oxygen production technologies mainly include molecular sieve adsorption method (PSA method), low-temperature separation method, etc.

[0003] Among them, PSA technology is based on the principle of selective adsorption and pressure swing desorption of adsorbents. It realizes gas separation and recovery through pressure changes in the adsorption tower. The air enters the adsorption tower after compression. The adsorbent (such as zeolite molecular sieve) adsorbs nitrogen molecules in the air under high pressure, while oxygen molecules are not adsorbed due to their slow diffusion rate and are discharged from the adsorption tower.

[0004] The existing PSA oxygen production technology requires a series of equipment such as air compressors, air filtration equipment, and dual-tower adsorption towers. It occupies a large area and has high requirements for placement space. The adsorption equipment mainly uses dual adsorption towers. While one adsorption tower is adsorbing and producing oxygen, the other adsorption tower is regenerating the molecular sieve. However, the adsorption towers are tall and inconvenient to place. If one of the adsorption towers fails, the oxygen production efficiency will be greatly reduced, affecting production efficiency. Summary of the Invention

[0015] If there is a problem with the molecular sieve and it needs to be replaced, unscrew the mounting screws on the packaging plate on the molecular sieve plate, pour out the molecular sieve in the molecular sieve plate through the discharge port, then add new molecular sieve from the feed port, and then install the packaging plate. Then, you can insert the molecular sieve plate into the sliding seat through the positioning groove and the fixing block.

[0016] Preferably, an air pressure valve and a first integrated pipe connecting multiple first guide grooves are installed on the top of the movable guide seat, the first integrated pipe is connected to a T-shaped branch pipe, and the two branches of the branch pipe are respectively installed with a first electric-controlled valve and a second electric-controlled valve, and a second integrated pipe connecting multiple second guide grooves is installed on the outside of the fixed guide seat, the first integrated pipe is also connected to a T-shaped branch pipe, and the two branches of the branch pipe are respectively installed with a third electric-controlled valve and a fourth electric-controlled valve, and a programmable controller is installed at the rear end of the stand, and the first electric-controlled valve, the second electric-controlled valve, the third electric-controlled valve and the fourth electric-controlled valve are all electrically connected to the controller.

[0020] The present invention has the following beneficial effects: 1. The present invention uses a T-shaped three-dimensional integrated rack to install air compression equipment, primary filtration equipment, and drying equipment for pre-treating air inside the rack, multiple groups of modular oxygen production units are installed on both sides of the rack, and regeneration equipment and oxygen tanks are installed on the top of the rack. This not only reduces the height of the adsorption equipment and the height requirement of the oxygen production equipment, but the integrated and compact installation also reduces the deployment space of the complete oxygen production equipment and improves space utilization.

[0021] 2. The present invention uses multiple box-type oxygen production units to replace the traditional double adsorption towers. Each oxygen production unit can independently perform adsorption oxygen production or molecular sieve regeneration through intelligently controlled electric control valves. The electric control valves are adjusted so that only one oxygen production unit needs to be regenerated during molecular sieve regeneration, and all oxygen production units are regenerated in sequence. Compared with the traditional double tower structure in which one tower works while the other tower produces oxygen by adsorption, the molecular sieve utilization rate is higher at the same time while the total amount of molecular sieve remains unchanged, thereby improving the oxygen production efficiency.

[0022] 3. In the present invention, each oxygen production unit is also provided with a plurality of sieve plates loaded with molecular sieves. Not only are the oxygen production units independent of each other, but the molecular sieve plates in the same oxygen production unit are also independent of each other. When the adsorption equipment fails, the oxygen production unit at the fault will not affect other oxygen production units, and the faulty molecular sieve plate in the oxygen production unit will not affect other molecular sieve plates. The molecular sieve plates can be installed in a quick plug-in manner, reducing the impact of the adsorption equipment failure on the oxygen production efficiency. In addition, during adsorption, the flow rate in each molecular sieve plate is small, the stroke is short, and the efficiency of the molecular sieve recoil regeneration is high, which further improves the oxygen production efficiency.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Furthermore, the oxygen production and delivery assembly 6 includes an oxygen storage tank 61 installed on the top of the stand 12 and an inlet pump 62 symmetrically installed on the buffer storage tank 24. The input end of the inlet pump 62 is connected to the buffer tank, and the output end of the inlet pump 62 is installed with a first connecting pipe 64.

The second connecting pipe 65 is connected to the multiple second integrated pipes 331 on one side of the stand 12 through the third electric control valve 332 on each second integrated pipe 331.

[0039] The oxygen production process of a single oxygen production unit 3 is as follows: the first electrically controlled valve 312 and the fourth electrically controlled valve 333 are closed, and the first connecting pipe 64 of the oxygen production unit 3 transports pressurized air to the first integrated pipe 311 on one side. The pressurized air passes through the second electrically controlled valve 313 and along the first integrated pipe 311 into the movable guide seat 31, and then enters the molecular sieve plate 4 through the first guide groove 314. The pressurized air passes through the molecular sieve in the middle of the molecular sieve plate 4 for adsorption to produce oxygen. The oxygen passes through the molecular sieve and enters the fixed guide seat 33 through the second guide groove 334. The oxygen then enters the second integrated pipe and passes through the third electrically controlled valve 332 into the second connecting pipe 65. The oxygen enters the input pipe 63 along the second connecting pipe 65 and finally enters the oxygen storage tank 61 through the input pipe 63. In a specific implementation process, the molecular sieve regeneration component 7 includes an outlet pump 71 and a gas tank 72 installed on the top of the stand 12. The gas tank 72 is symmetrically installed with a third connecting pipe 73. The third connecting pipe 73 is connected to the multiple second integrated pipes 331 on one side of the stand 12 through the fourth electric-controlled valve 333 on each second integrated pipe 331. The output end of the outlet pump 71 is symmetrically installed with a fourth connecting pipe 74. The fourth connecting pipe 74 is connected to the multiple first integrated pipes 311 on one side of the stand 12 through the first electric-controlled valve 312 on each first integrated pipe 311.

[0040] The second electrically controlled valve 313 and the third electrically controlled valve 332 of the oxygen production unit 3 undergoing regeneration are closed, and the regeneration gas in the gas tank 72 is transported to the second integrated pipe through the third connecting pipe 73. The regeneration gas enters the fixed guide seat 33 from the second integrated pipe, and is then ejected from the second guide groove 334 to reversely regenerate the molecular sieve in the molecular sieve plate 4. The adsorbed gas and the regeneration gas blown down enter the movable guide seat 31, and then enter the first integrated pipe, and are finally discharged through the fourth connecting pipe 74, completing the regeneration of the molecular sieve of the oxygen production unit 3.

[0041] It should be noted that multiple oxygen production units 3 can independently perform oxygen production and regeneration operations. During the actual production process, only a single oxygen production unit 3 is regenerated at the same time, so that all oxygen production units 3 are regenerated and restored in turn, and all other oxygen production units 3 are in the oxygen production state.

[0042] The use and function of the driving structure of the new low-energy chain oxygen production equipment 1 provided by the present invention are as follows: In the working state, the air raw material is transported to the air compressor 21 through the external air supply equipment, and the air is pressurized. After the air is pressurized, it passes through the primary filter, the activated carbon filter and the high-efficiency filter in sequence. Among them, the primary filter removes larger dust and particulate matter in the air and intercepts particles ≥1μm. The activated carbon adsorber removes oil mist, grease and other organic matter in the air. The high-efficiency filter further removes tiny particles and residual impurities and intercepts particles larger than 0.01μm. After the filtration is completed, the air enters the air dryer 23 to remove moisture in the air, and then the pre-treated air enters the buffer storage tank 24; The inlet pump 62 on the buffer storage tank 24 delivers the treated pressurized air to the first connecting pipe 64. At this time, the first electrically controlled valve 312 and the fourth electrically controlled valve 333 are closed. The first connecting pipe 64 at the oxygen production unit 3 delivers the pressurized air to the first integrated pipe 311 on one side. The pressurized air passes through the second electrically controlled valve 313 and enters the movable guide seat 31 along the first integrated pipe 311, and then enters the molecular sieve plate 4 through the first guide groove 314. The pressurized air passes through the molecular sieve in the middle of the molecular sieve plate 4 for adsorption and oxygen production. The oxygen passes through the molecular sieve and enters the fixed guide seat 33 through the second guide groove 334.

[0043] The oxygen then enters the second integrated pipe and passes through the third electrically controlled valve 332 into the second connecting pipe 65. The oxygen then flows along the second connecting pipe 65 into the input pipe 63 and finally into the oxygen storage tank 61 through the input pipe 63, completing the oxygen production process of the oxygen production unit 3. During the regeneration process, the second electrically controlled valve 313 and the third electrically controlled valve 332 of the oxygen production unit 3 undergoing regeneration are closed, and the regeneration gas in the gas tank 72 is transported to the second integrated pipe through the third connecting pipe 73. The regeneration gas enters the fixed guide seat 33 from the second integrated pipe, and is then ejected from the second guide groove 334 to reversely regenerate the molecular sieve in the molecular sieve plate 4. The adsorbed gas and the regeneration gas blown down enter the movable guide seat 31, and then enter the first integrated pipe, and finally are discharged through the fourth connecting pipe 74, completing the regeneration of the molecular sieve in the oxygen production unit 3. When the oxygen production unit 3 fails, all the electric control valves of the oxygen production unit 3 at the faulty location are closed. At this time, the oxygen production unit 3 is disconnected from other pipelines. The servo cylinder 52 at the oxygen production unit 3 is started by the controller. The servo cylinder 52 drives the movable guide seat 31 to move toward the stand 12 through the telescopic rod 53, so that the movable guide seat 31 is away from the fixed guide seat 33. At this time, the oxygen production unit 3 can be inspected and repaired, and the molecular sieve plate 4 is slid back and forth through the sliding seat 35 to disconnect the molecular sieve from the movable guide seat 31 and the fixed guide seat 33.

[0044] Then lift the molecular sieve plate 4 upward and remove it. If there is a problem with the molecular sieve and it needs to be replaced, unscrew the mounting screws 44 on the packaging plate 42 on the molecular sieve plate 4, pour out the molecular sieve in the molecular sieve plate 4 through the discharge port 451, and then add new molecular sieve from the feeding port 452. After installing the packaging plate 42, the molecular sieve plate 4 can be inserted into the sliding seat 35 through the positioning groove 46 and the fixed block 351.
