[0004] The regeneration tower is a device for desorbing the absorbed or adsorbed substances from the adsorbent saturated with adsorption to regenerate the adsorbent, the adsorbent saturated with adsorption is supplied into the regeneration tower, the regenerated adsorbent is discharged from the regeneration tower and is supplied into the adsorption tower, for example, to perform adsorption purification of flue gas. In the related art, in order to facilitate the inspection of the flow condition of the adsorbent in the regeneration tower to ensure the smooth progress of the regeneration of the adsorbent, a material level meter is usually arranged at the top of the regeneration tower to detect the material level at the top of the regeneration tower, to determine whether the material supply is normal, and then to control the unloader to unload into the regeneration tower. However, the material level monitoring method in the related art has the problems of low monitoring accuracy and even monitoring failure. SUMMARY

[0005] The present disclosure is made based on the discovery and realization of the inventors on the following facts and problems:

[0006] In the related art, in order to monitor the operation of the regeneration tower, a material level meter is arranged at the top of the inner cavity of the regeneration tower to detect the material level, when the material level is too high, the unloader is controlled to reduce the material supply into the regeneration tower, when the material level is too low, the unloader is controlled to increase the material supply into the regeneration tower, in other words, only by detecting the height of the material level at the top and by controlling the amount of unloading of the unloader, the regeneration tower is smoothly operated. The inventors have found and realized through research that the detection method in the related art cannot timely, accurately and effectively determine the root cause of the problem, for example, when the material level meter itself is damaged or has other problems causing the material level at the top of the regeneration tower to be too high or too low, the amount of unloading controlled by the unloader can only control the material level at the top, and cannot determine the root cause and reason of the problem causing the material level to be too high or too low, for example, the position of the blockage of the material in the regeneration tower cannot be determined, and the problem cannot be well solved, resulting in inaccurate and untimely monitoring of the material level of the regeneration tower, and even failure, and the regeneration tower cannot be effectively operated in a reliable manner, affecting the efficiency.

DETAILED DESCRIPTION

[0040] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as a limitation of the present disclosure.

[0041] The regenerated tower with material level monitoring function of the first aspect of the present disclosure is described below, as shown in FIGS. 1-2, the regenerated tower with material level monitoring function includes a tower body 1, a first material level meter 2, a second material level meter 3, and a controller 7. Specifically, the tower body 1 extends in the up-down direction, and the tower body 1 has an inner cavity extending in the up-down direction.

[0042] The inner cavity of the tower body 1 includes a material distribution section 11, a material discharge section, and a plurality of material discharge sections 12. The plurality of material discharge sections 12 are located between the material distribution section 11 and the material discharge section and are arranged in the up-down direction, and the adjacent material discharge sections 12 have a buffer section 13 therebetween. Specifically, the material distribution section 11 has a material distribution layer 111 therein, and the material distribution layer 111 is stacked by the adsorption unit 8. The adsorption unit 8 in the material distribution section 11 falls through the material discharge section 12 to the buffer section 13 and is stacked in the buffer section 13.

[0043] The first material level meter 2 is arranged in the material distribution section 11 and is used to monitor the material level height in the material distribution section 11.

[0044] The second material level meter 3 is arranged in the buffer section 13 and is used to monitor the material level height in the buffer section 13.

[0045] The controller 7 determines whether the material discharge section 12 is blocked according to the monitored material level height in the material distribution section 11 and the predetermined material level height in the buffer section 13.

[0046] The regenerated tower with material level monitoring function of the present disclosure embodiment determines that the material discharge section 12 between the material distribution section 11 and the buffer section 13 is blocked when the material level height in the material distribution section 11 is too high and the material level height in the buffer section 13 adjacent to the material distribution section 11 and below the material distribution section 11 is too low.

[0047] When the material level in the material section 11 is normal, the material level in the buffer section 13 adjacent to and below the material section 11 is too high, and the material level in the buffer section 13 below and adjacent to the buffer section 13 is too low, it is judged that the lower section 12 between the buffer section 13 and the buffer section 13 adjacent to the buffer section 13 is blocked. Thus, the regenerated tower with the material level monitoring function of the embodiment of the present disclosure can not only judge whether the lower section 12 is blocked, but also judge which lower section 12 is blocked, so that the regenerated tower with the material level monitoring function of the embodiment of the present disclosure has the material level detection function with high monitoring precision, timely monitoring and high efficiency.

[0048] In some embodiments, the adsorption unit 8 comprises a gas-permeable shell 81 and an adsorbent 82 filled inside the gas-permeable shell 81. The adsorbent 82 can be a granular or powdered adsorbent 82, or an adsorbent 82 body made of powdered or granular adsorbent 82. For example, a spherical body or a cylindrical body formed by a binder from powdered or granular adsorbent 82, of course, the adsorbent 82 body can be further formed with a protective shell, such as a gas-permeable film covering the outside of the adsorbent 82 body, to improve the strength of the adsorbent 82 body. The gas-permeable shell 81 has gas-permeable holes, through which flue gas can enter the gas-permeable shell 81, and the flue gas can pass through the gaps between adjacent adsorbents 82 and / or the pores of the adsorbents 82 themselves, thereby reducing direct collision, friction and wear between the adsorbents 82, and reducing dust generation. The gas-permeable shell 81 can be a rotating body such as a sphere or a cylinder, wherein the diameter of the adsorption unit 8 is 10-100 mm, and the diameter of the adsorbent 82 is 1-10 mm.

[0049] In some embodiments, the first material level meter 2 monitors that the material level in the material section 11 is too high, the second material level meter 3 monitors that the material level in each buffer section 13 is normal, and it is observed that the material level in the discharge section is too low, it is judged that the lowermost lower section 12 is blocked.

[0050] In some embodiments, the second material level meter 3 is also provided in the discharge section, and the controller 7 judges whether the lower section 12 is blocked according to the monitored material level in the material section 11, the material level in the buffer section 13 and the material level in the discharge section.

[0051] Specifically, when the material level in the material section 11 is too high and the material level in the discharge section is too low, it is judged that a certain lower section 12 between the material section 11 and the discharge section is blocked, and it is further judged which lower section 12 is blocked by the material level in the buffer section 13 monitored by the second material level meter 3 in the adjacent buffer section 13.

[0052] In some embodiments, each buffer section 13 is provided with a plurality of second level meters 3 arranged along the circumference of the tower body 1, which can further strengthen the monitoring of the level height in the buffer section 13 by the second level meters 3, and when one of the second level meters 3 in the buffer section 13 is inaccurate, it will not affect the measurement of the level height in the buffer section 13 by other level meters, thereby ensuring the monitoring accuracy of the regenerative tower with the level monitoring function in the embodiments of the present disclosure.

[0053] In some embodiments, the tower body 1 is further provided with a feed inlet 15 and a discharge outlet 16. The feed inlet 15 is located at the top of the tower body 1 and communicates with the distribution section 11, and the discharge outlet 16 is located at the bottom of the tower body 1 and communicates with the lower distribution section 12 below.

[0054] The regenerative tower with the level monitoring function further comprises a bin 4, which communicates with the feed inlet 15 to provide the adsorption units 8 into the distribution section 11 through the feed inlet 15.

[0055] In some embodiments, the first level meter 2 is a radio frequency admittance level meter, and the second level meter 3 is a non-rotation level meter. The distribution section 11 is further provided with the second level meter 3, and the controller 7 determines whether the blockage occurs in the lower distribution section 12 according to the level height in the distribution section 11 and the level height in the buffer section 13 monitored by the first level meter 2 and the second level meter 3.

[0056] Specifically, the radio frequency admittance level meter determines the level of the distribution layer 111 in the distribution section 11 by emitting rays to the distribution layer 111. The non-rotation level meter comprises a blade (not shown), which stops rotating when the adsorption unit 8 exists and rotates when it is not blocked. The second level meter 3 uses an electromechanical potential control principle to contact measure the level. The second level meter 3 has an indicator light (not shown) thereon. When there is no adsorption unit 8 in the buffer section 13, there is no material at the position of the blade, the second level meter 3 is powered on, the indicator light is on, and the blade rotates counterclockwise. When there is an adsorption unit 8 in the buffer section 13, the rotation of the blade is blocked, the control signal is converted, and the motor power of the second level meter 3 is disconnected. This state is maintained until there is no material in the buffer section 13 where the blade is located, the second level meter 3 is automatically reset, the motor power is connected, the indicator light is on, and the blade starts to rotate, and the control signal is switched.

[0057] The second level meter 3 in the distribution section 11 can combine the advantages of the two types of level meters to monitor the level height of the distribution layer 111, and in combination with the level height monitored by the second level meter in the buffer section 13, to determine whether the blockage occurs in the lower distribution section 12 between the distribution section 11 and the buffer section 13. In addition, the complementarity of the two types of level meters can also reduce the situation that the position of the adsorption unit 8 cannot be accurately determined when a single type of level meter fails.

[0058] In some embodiments, the unloading section 12 is provided with a plurality of unloading pipes 5 for guiding the falling of the adsorption units 8, the unloading section 12 is three, the topmost unloading section 12 is provided with a preheating medium for preheating the adsorption units 8 so as to form the topmost unloading section 12 into a preheating section, the middle unloading section 12 is provided with a heating medium for heating the adsorption units 8 so as to form the middle unloading section 12 into a regeneration section, and the bottommost unloading section 12 is provided with a cooling medium for cooling the adsorption units 8 so as to form the bottommost unloading section 12 into a cooling section. Specifically, the adsorption units 8 are low-temperature adsorption at the bottommost unloading section 12, and the low temperature is room temperature and below. In some embodiments, the low temperature is below 0°C. In some embodiments, the low temperature is -20℃ to -15℃.

[0059] In some embodiments, the unloading section 12 is further provided with a plurality of baffles 6 arranged in the up-down direction, and the baffles 6 are used to define the flow channel of the adsorption units 8.

[0060] The method for monitoring the material level of the regeneration tower according to the second aspect of the present disclosure is described below.

[0061] The inner cavity of the tower body 1 includes a feeding section 11 for forming a material layer 111, a discharging section, and a plurality of unloading sections 12 arranged in the up-down direction between the feeding section 11 and the discharging section, and the adjacent unloading sections 12 are provided with a buffer section 13 for stacking the adsorption units 8.

[0062] The method for monitoring the material level of the regeneration tower according to the embodiments of the present disclosure includes:

[0063] The material level height of the material layer 111 in the feeding section 11 is monitored. Specifically, the material level height of the material layer 111 is monitored by the first material level meter 2 and the second material level meter 3.

[0064] The material level height in the buffer section 13 is monitored. Specifically, the material level height in the buffer section 13 is monitored by the second material level meter 3.

[0065] According to the material level height in the feeding section 11 and the material level height in the buffer section 13, it is determined whether the unloading section 12 is blocked.

[0066] The method for monitoring the material level of the regeneration tower according to the embodiments of the present disclosure can improve the material level monitoring accuracy, timeliness and effectiveness of the regeneration tower by simultaneously monitoring the material level height of the material layer 111 in the feeding section 11 and the material level height in the buffer section 13 to determine which unloading section 12 is blocked, and the flow of the adsorption units 8 can be monitored by the controller 7 to reduce the frequency of manual observation.

[0067] In some embodiments, the regenerated tower with the material level monitoring function further comprises a method for monitoring the material level in the discharging section, and determining whether the blockage occurs in the discharging section 12 according to the material level in the feeding section 11, the material level in the buffer section 13 and the material level in the discharging section.

[0068] Specifically, when the material level in the feeding section 11 is monitored to be too high and the material level in the discharging section is monitored to be too low, it is determined that the blockage occurs in the discharging section 12. Further, the material level monitored by the second material level gauge 3 in the buffer section 13 is monitored to determine which discharging section 12 the blockage occurs in. Thus, the regenerated tower with the material level monitoring function according to the embodiments of the present disclosure can timely, accurately and efficiently find out the root cause and quickly make corresponding countermeasures.

[0069] In some embodiments, if the material level in the feeding section 11 is monitored to be greater than the first threshold value and the material level in at least one of the buffer section 13 or the discharging section is monitored to be lower than the second threshold value, it is determined that the blockage occurs in at least one of the discharging sections 12.

[0070] Specifically, the material level in the feeding section 11 has a first threshold value, and the first material level gauge 2 in the feeding section 11 is higher than the first threshold value. The material level in the buffer section 13 has a second threshold value, and the second material level gauge in the buffer section 13 is lower than the second threshold value. When the material level in the feeding section 11 is higher than the first threshold value and the material level in the buffer section 13 is lower than the second threshold value, it is determined that the blockage occurs in at least one of the discharging sections 12. Further, the positional relationship between the material level in the buffer section 13 and the second threshold value is observed to determine which discharging section 12 the blockage occurs in. Thus, the regenerated tower with the material level monitoring function according to the embodiments of the present disclosure can timely, accurately and efficiently find out the root cause and quickly make corresponding countermeasures.

[0071] In some embodiments, if the material level of the material layer 111 is monitored to be greater than the first threshold value and the material level in the uppermost buffer section 13 is monitored to be lower than the second threshold value, it is determined that the blockage occurs in the discharging section 12 located above the uppermost buffer section 13 and adjacent to the uppermost buffer section 13. If the material level in the uppermost buffer section 13 is not lower than the second threshold value, the material levels in the buffer section 13 and the discharging section below are sequentially determined to be lower than the second threshold value to determine which discharging section 12 the blockage occurs in. Thus, it can be accurately and efficiently determined which discharging section 12 the blockage occurs in and timely solved.

[0072] In some embodiments, monitoring the material level in the feeding section 11 comprises jointly monitoring the material level in the feeding section 11 by using the radio frequency admittance material level gauge and the anti-rotation material level gauge.

[0073] Specifically, by monitoring the adsorption unit 8 of the cloth layer 111 simultaneously through the radio frequency admittance stock level meter and the resistance spin stock level meter, the advantages of the two types of stock level meters can be combined to monitor the position of the adsorption unit 8 of the cloth layer 111, improve the monitoring accuracy, and reduce the situation that the position of the adsorption unit 8 cannot be accurately judged when a single type of stock level meter fails.
