Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve regeneration devices, in particular to a boiler steam waste heat molecular sieve regeneration device. Background Art

[0002] Molecular sieve is a material such as aluminosilicate or phosphate with uniform microporous structure. It is widely used in industrial production for drying, purification and separation of gases and liquids. In actual use, molecular sieve will gradually become saturated due to the adsorption of water, carbon dioxide and other impurities, and lose its adsorption capacity. Therefore, it needs to be regenerated regularly to restore its adsorption performance.

[0003] There are two main methods for regenerating molecular sieves: heating regeneration and pressure reduction regeneration. Pressure reduction regeneration is generally used in gas phase adsorption process to remove adsorbate by reducing pressure and back-blowing with inert gas; heating regeneration is to desorb adsorbate in molecular sieve by increasing temperature. In industry, preheated regeneration gas is often used to purge molecular sieve to about 200°C to achieve this.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figures 1 to 8 , the present invention provides a technical solution:

[0049] A boiler steam waste heat molecular sieve regeneration device comprises a mounting frame 1, a PLC control box 2 is fixedly mounted at the middle position on the left side of the mounting frame 1, and the PLC control box 2 can detect a steam temperature monitor 302, a steam flow valve 305 and a nitrogen temperature flow monitor 503 for subsequent operations, such as Figure 2 shown.

[0050] A vertical boiler 3 is fixedly installed on the left side inside the mounting frame 1, wherein a steam pipe 301 is fixedly installed at the top center position of the boiler 3, and the lower end of the steam pipe 301 and the interior of the boiler 3 are in a through state. Therefore, during use, the steam generated inside the boiler 3 will enter the interior of the steam pipe 301, so that the regeneration gas for subsequent operations can be heated. Then, a steam temperature monitor 302 is fixedly installed on the circumferential surface of the upper end of the steam pipe 301, and the steam temperature monitor 302 can monitor the temperature of the steam discharged from the boiler 3 in real time. After monitoring the temperature of the steam, the steam temperature monitor 302 will transmit the data to the PLC control box 2 in real time, so as to facilitate the PLC control box 2 to integrate the data and facilitate subsequent operations, such as Figure 2 shown.

[0051] The left side of the upper end of the steam pipe 301 is a curved structure, which is used to slow down the flow speed of the steam and prevent excessive steam from rushing into the interior of the gas-water separator 303 at the same time. The gas-water separator 303 is fixedly installed on the right side of the upper end of the steam pipe 301. The gas-water separator 303 and the steam pipe 301 are in a through state, and the steam inside the steam pipe 301 will enter the interior of the gas-water separator 303. The gas-water separator 303 can separate the water molecules in the steam, so as to prevent the moisture in the steam from affecting the subsequent operation effect and prevent the molecular sieve beads 412 from losing the operation effect. Figure 3 shown.

[0052] Secondly, a vertical drain pipe 307 is fixedly installed in the middle of the lower end of the gas-water separator 303, and the lower end of the drain pipe 307 is located on the inner side of the lower end of the mounting frame 1. Under the action of the drain pipe 307, the water inside the gas-water separator 303 can be discharged through the drain pipe 307 to avoid the gas-water separator 303 being filled with too much water, which makes the gas-water separator 303 unable to operate. Secondly, the lower end of the drain pipe 307 passes through the mounting frame 1, such as Figure 2 As shown, a circular hole is provided on the mounting frame 1 for the delivery pipe 304 to pass through, so that the water delivered by the drainage pipe 307 will not be too high from the ground, which may cause splashing of the water.

[0053] A delivery pipe 304 is fixedly installed at the right end of the gas-water separator 303, and the delivery pipe 304 and the gas-water separator 303 are in a through-connected state. At this time, the steam discharged from the water will enter the interior of the delivery pipe 304, and a steam flow valve 305 is fixedly installed on the circumferential surface of the delivery pipe 304. Under the action of the steam flow valve 305, the steam flow passing through can be adjusted, so that it can be adjusted according to the subsequent regeneration gas situation. The steam flow valve 305 and the PLC control box 2 are also electrically connected, and the steam flow valve 305 can be started, stopped and adjusted according to the actual situation of the subsequent regeneration gas, such as Figure 3 shown.

[0054] A steam preheater 306 is fixedly installed at the lower end of the delivery pipe 304, and the steam inside the delivery pipe 304 will enter the steam preheater 306, so that the regeneration gas can be heated inside the steam preheater 306; a nitrogen bottle 5 is fixedly installed at the right end of the mounting frame 1, and a fan 501 is fixedly installed on the top of the nitrogen bottle 5. Under the action of the fan 501, the stability of the regeneration gas flow rate can be guaranteed, and then it can be guaranteed that the regeneration gas will not affect the subsequent operation effect. Secondly, a nitrogen delivery pipe 502 is fixedly installed on the top of the fan 501, and the upper left end of the nitrogen delivery pipe 502 is fixedly connected to the right end of the steam preheater 306 and is in a through state. In this way, the internal nitrogen of the nitrogen delivery pipe 502 can enter the steam preheater 306, and then mix with the steam inside the steam preheater 306, and then under the action of the steam, the temperature of the regeneration gas can be gradually increased, and the increased regeneration gas will enter the subsequent regeneration tower 4. Figure 3 As shown, a circular structured pipe is fixedly installed between the lower end of the steam preheater 306 and the regeneration tower 4, and an opening and closing valve is provided on the pipe. The valve can prevent the regeneration gas from entering the interior of the regeneration tower 4 before the temperature of the regeneration gas reaches a predetermined value.

[0055] A nitrogen temperature flow monitor 503 is fixedly installed on the circumferential surface of the nitrogen delivery pipe 502. Figure 4 As shown; during use, nitrogen will pass through the nitrogen temperature flow monitor 503, and the nitrogen temperature flow monitor 503 can monitor the temperature and flow rate of the regeneration gas flowing through, and the monitored data will be transmitted to the PLC control box 2, and the PLC control box 2 can operate the steam flow valve 305 according to the temperature and flow rate of the nitrogen, so that the steam passing through can meet the operating requirements, avoid excessive steam causing the temperature of the regeneration gas to be too high, thereby avoiding adverse conditions in the desorption process and avoiding the temperature of the regeneration gas being too low.

[0056] The top of the regeneration tower 4 is located on the right side of the steam preheater 306, and a first air inlet pipe 401 is fixedly installed thereon. The right side of the upper end of the first air inlet pipe 401 can be connected to an external pipeline, so that the gas to be filtered from the outside can enter the interior of the regeneration tower 4, and then the gas is filtered under the action of the molecular sieve beads 412 inside the regeneration tower 4. Then, a first transverse air outlet pipe 402 is fixedly installed on the circumferential surface of the lower end of the regeneration tower 4, and under the action of the first air outlet pipe 402, the filtered gas can be discharged from the first air outlet pipe 402, as shown in FIG. Figure 5 shown.

[0057] Three partitions 406 are fixedly installed at the center of the regeneration tower 4, and a through hole 407 is opened between two adjacent partitions 406, wherein the front and rear sides of the partition 406 are fixedly connected to the inner wall of the regeneration tower 4, so as to ensure the stability of the partition 406. Secondly, a drive motor 408 is fixedly installed at the center of the lower end of the regeneration tower 4, and the output shaft of the drive motor 408 passes through the top of the regeneration tower 4 and is rotatably connected to the inner top of the regeneration tower 4. Secondly, two mounting disks 409 are fixedly installed on the circumferential surface of the output shaft of the drive motor 408, and the mounting disks 409 are respectively located in the through holes 407 between two adjacent partitions 406, such as Figure 5 As shown, the outer diameter of the mounting plate 409 and the inner diameter of the regeneration tower 4 are in a consistent state.

[0058] When the drive motor 408 is started, the output shaft of the drive motor 408 will rotate synchronously with the two mounting disks 409. The interior of the mounting disk 409 is a cavity structure, and a separation plate 411 is fixedly installed inside the cavity. The separation plate 411 divides the interior of the mounting disk 409 into two parts. Secondly, a through hole 410 is provided from the upper end surface to the lower end surface of the mounting disk 409 to allow gas to pass through. Figure 8 shown.

[0059] A plurality of molecular sieve beads 412 are respectively filled on the left and right sides of the separation plate 411 inside the mounting disk 409. The molecular sieve beads 412 can adsorb impurities in the gas, thereby making the gas fresher after being discharged.

[0060] Among them, under the action of the partition 406, the molecular sieve beads 412 inside the mounting plate 409 can be in a state of half operation and half desorption, so that the regeneration tower 4 can be in a state of uninterrupted operation, thereby improving the efficiency of the operation; and the first air inlet pipe 401 and the first air outlet pipe 402 are in a through state, and the pipeline at the lower end of the steam preheater 306 and the subsequent second air outlet pipe 403 are in a through state, so there will be no mutual interference and influence, ensuring a good state of desorption and filtration.

[0061] Among them, the second air outlet pipe 403 is fixedly installed at the lower end of the regeneration tower 4, so that the regenerated gas after desorption can be discharged along the second air outlet pipe 403, and a circular structure shell 404 is slidably installed inside the second air outlet pipe 403. The interior of the shell 404 is a cavity structure, and both ends are in a through state. A filter screen 405 is fixedly installed inside the shell 404. When the regenerated gas enters the interior of the shell 404, the regenerated gas can be filtered through the filter screen 405, so as to avoid the impurities in the regenerated gas from mixing with the outside air and causing air pollution. Secondly, since the shell 404 is slidably installed inside the second air outlet pipe 403, the filter screen 405 can be replaced at any time during use to ensure the filtering effect.

[0062] Working principle: First, the boiler 3 operates, and the generated steam will enter the interior of the steam pipe 301. Then, the steam temperature will be monitored under the action of the steam temperature monitor 302, and then the temperature data will be transmitted to the PLC control box 2. At this time, the steam will enter the interior of the gas-water separator 303.

[0063] The gas-water separator 303 can remove the water in the steam, and then the water will be discharged through the drain pipe 307.

[0064] After the steam has been dehydrated, it enters the interior of the delivery pipe 304 and then enters the interior of the steam preheater 306 .

[0065] Start the nitrogen bottle 5. The regenerated gas in the nitrogen bottle 5 will stably enter the interior of the nitrogen delivery pipe 502 under the action of the fan 501, and then pass through the nitrogen temperature flow monitor 503. The nitrogen temperature flow monitor 503 transmits the monitored data to the PLC control box 2, and the PLC control box 2 adjusts the steam flow valve 305.

[0066] At this time, the regeneration gas enters the steam preheater 306, and after mixing with the internal steam, its temperature will be in a rising state. When the temperature reaches a predetermined value, it will enter the regeneration tower 4. It should be noted that a temperature monitoring device is provided inside the steam preheater 306 to monitor the temperature rise state of the regeneration gas in real time to ensure temperature adaptation.

[0067] After the regeneration gas enters the regeneration tower 4, it passes through the mounting plate 409 layer by layer, and then desorbs the molecular sieve beads 412 inside the mounting plate 409, so that the molecular sieve beads 412 can be regenerated, thereby maintaining the operation for a long time. It should be noted that a pressure and temperature monitoring device can be installed on the outside of the upper end of the second gas outlet pipe 403 inside the regeneration tower 4, which is used to monitor the pressure and temperature conditions inside the regeneration tower 4 in real time, so as to adjust the regeneration tower 4 when the pressure and temperature are too high.

[0068] The desorbed regeneration gas will enter the interior of the second gas outlet pipe 403 and then be discharged through the filter screen 405 .

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
