Description

Technical Field

[0001] The invention relates to the technical field of pressure swing adsorption oxygen production, and in particular to a pressure swing adsorption oxygen production device. Background Art

[0002] Pressure swing adsorption oxygen production technology is divided into three process flows: high-pressure adsorption atmospheric pressure desorption, atmospheric pressure adsorption vacuum desorption and low-pressure adsorption vacuum desorption. The above three process flows have the same process principles and only different working pressures. Among them, the VPSA process has the lowest energy consumption, advanced technology, stable equipment and economy, representing the development trend of pressure swing adsorption oxygen production. The main function of pressure swing adsorption oxygen production equipment (PSA oxygen production equipment) is to separate high-purity oxygen from the air to meet the needs of different fields.

[0003] In the prior art, since the operation process of the pressure swing adsorption oxygen production equipment is carried out through the processes of air compression-air cooling-air filtration, in the process of pressure swing adsorption oxygen production, the ambient air is first compressed by an air compressor to increase the air pressure to provide sufficient power for the subsequent oxygen production process. Therefore, the air filtration step of the pressure swing adsorption oxygen production equipment is carried out after air compression, and then a multi-stage filter is used to filter the air. Then, there will be dust and other particles in the air of the working environment. These particles will be filtered by the multi-stage filter. Under long-term operation, the burden of the filter may be increased, causing it to be blocked or damaged. In addition, after the filter of the pressure swing adsorption oxygen production equipment has filtered a large number of dust particles for a long time, dust accumulation will occur, which will affect the air quality entering the subsequent steps.

[0046] Working principle: Please refer to Figure 1-Figure 16As shown, through the set wind plate 9, when the staff uses the air compressor 2 to compress the air and input it into the interior of the pressure swing adsorption oxygen generator body 1, when the air compressor 2 is running, the air compressor 2 will inhale a large amount of air from the surrounding environment to meet its working needs, and then generate a certain suction force during the inhalation process to pump the surrounding air, and then in the process of the air being continuously sucked into the compressor, its suction force will affect the wind plate 9, and then the wind plate 9 will drive the rotating column 8, the support frame 10, the support plate 11 and the rotating frame 12 to rotate, and then the suction force generated by the air compressor 2 will be transmitted to the air inlet hood 5 through the air inlet hole 4. Since the opening of the air inlet hood 5 is inclined downward at forty-five degrees, the suction force of the air compressor 2 will then draw air in from the bottom of the air inlet hood 5 through the air inlet hood 5, thereby reducing the dust in the air through the shielding of the air inlet hood 5. On the exhaust path of the air compressor 2, when the air in the working environment is drawn in, it passes through the inside of the air inlet hood 5 and contacts the surface of the sticky dust pad 13, and then the sticky property of the sticky dust pad 13 can adhere to the dust and other particulate impurities in the inhaled air, and then the air passes through the dust shield net 30 for the second step of filtration, and then enters the inside of the dust shield shell 3 and is sucked into the air compressor 2, so as to facilitate the air particle blocking and filtering at the front end of the operation process of the PSA oxygen generator body 1 and the air compressor 2, and prevent the compressed air from entering the interior of the PSA oxygen generator body 1, and the air contains a large amount of dust and other impurities, which causes the filter and molecular sieve in the PSA oxygen generator body 1 to be blocked, resulting in a decrease in equipment performance. At the same time, the front-end filtration can reduce the operating burden of the filter in the PSA oxygen generator body 1, reduce the cleaning frequency of the filter of the PSA oxygen generator body 1, and increase the use time.

[0047] By means of the fixed block 14, the stabilizing column 19 is pulled upward to drive the magnet 20 and the limit block 18 to move upward, and then the magnet 20 will be away from the surface of the rotating frame 12, and the mutual adsorption between the magnet 20 and the rotating frame 12 will be released, so that the clamping of the sticky pad 13 can be released, and then the sticky pad 13 is moved out of the surface of the rotating frame 12, so as to facilitate the replacement of the sticky pad 13, and then after the new sticky pad 13 is placed on the surface of the rotating frame 12, the limit block 18, the stabilizing column 19 and the magnet 20 are reset, so that the magnet 20 and the rotating frame 12 are adsorbed together, so as to facilitate the clamping and restriction of the sticky pad 13.

[0048] By means of the provided clamping strip 29, when the staff is removing the sticky pad 13 above the support frame 10, they first move the sliding block 25 upward to drive the support column 27 and the clamping strip 29 to move and stretch the spring 24, so that the clamping strip 29 can be moved upward and away from the surface of the support frame 10, thereby releasing the clamping of the sticky pad 13 on the surface of the support frame 10, making it easier to remove and replace it.

[0049] Through the provision of the louver 34, when the staff needs a large amount of continuous compressed air from the air compressor 2, the staff drives the connecting block 41 and the rack 33 to move by moving the operating frame 40, and then the rack 33 will engage and drive the gear 36 to rotate during the movement, and the gear 36 will drive the rotating column 35 and the louver 34 to rotate during the rotation. At this time, several gears 36 and louver 34 rotate at the same time, so that multiple louver 34 can be opened in a louver shape, and each louver 34 is inclined at a forty-five degree angle to the dust shield shell 3, so that the blocking of the air vent 37 by several louver 34 can be released, so that a large amount of external air can enter the interior of the dust shield shell 3 through the air vent 37, so as to increase the amount of air inside the dust shield shell 3 so that the air compressor 2 can draw it in.

[0050] By setting up a water absorption cylinder 45, by placing a dehumidifier inside the water absorption cylinder 45, by placing activated carbon inside the purification cylinder 44, and then by placing a plurality of sealing covers 47 into the purification cylinder 44 and the water absorption cylinder 45 respectively, the openings of the purification cylinder 44 and the water absorption cylinder 45 can be covered, and then the air enters the dust shielding shell 3 and contacts with the activated carbon to adsorb organic matter, odor and other gases in the extracted air, so as to purify the air. At the same time, the dehumidifier can adsorb moisture from the air entering the dust shielding shell 3, so as to facilitate the treatment of the air before being drawn into the air compressor 2, and increase the quality of the air drawn into the air compressor 2.

[0051] 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.
