[0044] The above and / or additional aspects and advantages of the present invention will become apparent and readily understood from the following description of the embodiments taken in conjunction with the accompanying drawings, wherein:

[0045] Figure 1 This is a flowchart of a material recycling and distribution method according to an embodiment of the present invention;

[0046] Figure 2 This is a schematic diagram of a material recycling system according to an embodiment of the present invention;

[0047] Figure 3 This is a structural diagram of a material circulation and distribution device according to an embodiment of the present invention. Detailed Implementation

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0050] The material recycling and distribution method and apparatus according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0051] Figure 1 This is a flowchart of a material recycling and distribution method according to an embodiment of the present invention.

[0052] like Figure 1 As shown, the method includes:

[0053] S1, the adsorbent discharged from multiple adsorption towers is transported to the regeneration tower by the first chain bucket machine;

[0054] In one embodiment of the present invention, Figure 2 This is a schematic diagram of a material recycling system proposed in an embodiment of the present invention. Figure 2 As shown, the above material circulation system may include a first bucket elevator, a second bucket elevator, a third bucket elevator, multiple adsorption towers and a regeneration tower, and the multiple adsorption towers may be distributed in a column.

[0055] In one embodiment of the present invention, in order to achieve material balance between adsorption and regeneration, two signals, high material level and low material level, are set at the top of the regeneration tower. When the high material level signal alarms, it indicates that the regeneration tower is full of adsorbent and feeding is stopped. When the low material level signal alarms, it indicates that there is a lack of adsorbent in the regeneration tower and feeding is required to continuously feed into the regeneration tower and discharge from the regeneration tower is stopped, so as to achieve the purpose of rapid recovery of the material level in the regeneration tower.

[0056] Specifically, in one embodiment of the present invention, during the process of conveying the adsorbent discharged from multiple adsorption towers to the regeneration tower via the first chain bucket conveyor, the method may further include: in response to a high-level alarm in the regeneration tower, the adsorption tower discharge double-spindle stops operating, the first chain bucket conveyor stops, the regeneration tower feed double-spindle stops, and after a preset time delay after the high-level signal in the regeneration tower disappears, the regeneration tower feed double-spindle, the first chain bucket conveyor, and the discharge double-spindles of the multiple adsorption towers are started sequentially; in response to a low-level alarm in the regeneration tower, the regeneration tower discharge rotary valve stops operating, and after a preset time delay after the low-level signal in the regeneration tower disappears, the regeneration tower discharge rotary valve resumes operation.

[0057] The preset time can be set as needed; for example, the preset time can be 120 seconds.

[0058] S2, the adsorbent discharged from the regeneration tower is transported to the third chain bucket machine through the second chain bucket machine;

[0059] S3 distributes the adsorbent to multiple adsorption towers via a third-chain bucket elevator.

[0060] In one embodiment of the present invention, to ensure sufficient adsorbent in the adsorption towers, two layers of packing tanks are provided above each column of adsorption towers, such as... Figure 2 As shown, the material level in the adsorption tower is controlled by the high and low material levels on the upper and lower packing tanks. The packing tanks are divided into an upper packing tank and a lower packing tank. The lower packing tank has two material level signals (high and low), while the upper packing tank has two signal types: a high-level alarm and a material level radar (capable of continuously measuring material level height). Simultaneously, on / off valves are installed at the inlets of both the upper and lower packing tanks to control the opening and closing of the material flow channels.

[0061] Furthermore, in one embodiment of the present invention, the method for distributing adsorbent to multiple adsorption towers via a third-chain bucket elevator may include the following steps:

[0062] S31, the third chain bucket machine feeds the upper packing tank of the adsorption tower until the upper packing tank is full;

[0063] S32, Nitrogen purging protection is performed on the upper packing tank until the nitrogen pressure reaches the pressure set value;

[0064] S33, replenish the adsorbent from the upper packing tank to the lower packing tank of the adsorption tower until it flows by gravity to the adsorption tower, thus completing the distribution of the adsorbent in the adsorption tower. Repeat the above steps to distribute the adsorbent to multiple adsorption towers in turn until all adsorption towers have been distributed.

[0065] If the above-mentioned multiple adsorption towers are distributed in columns, the adsorbent can be distributed to the adsorption towers in columns.

[0066] Furthermore, in one embodiment of the present invention, the method described above, in which the third chain bucket elevator feeds the upper packing tank of the adsorption tower until the upper packing tank is full, may include the following steps:

[0067] Step 1: Determine whether the adsorption tower meets the conditions for starting feeding;

[0068] Step 2: If the adsorption tower meets the conditions for starting feeding, the third chain bucket machine will activate the discharge baffle to feed the adsorption tower until the upper packing tank reaches a high level or the level radar alarms, at which point the discharge baffle will be closed and the upper packing tank will be filled.

[0069] In one embodiment of the present invention, the above-mentioned conditions for initiating material replenishment may include:

[0070] Neither the packing level radar nor the level gauge on the adsorption tower triggered a high-level alarm.

[0071] The feed valve of the upper packing tank is open, and there is a signal indicating that it is fully open.

[0072] The feed valve of the lower packing tank is closed, and the relevant positioning signal is activated.

[0073] Furthermore, in one embodiment of the present invention, when the material level corresponding to the packing level radar or level gauge on the adsorption tower is greater than a preset value, the packing level radar or level gauge on the adsorption tower will trigger a high material level alarm.

[0074] In one embodiment of the present invention, if the adsorption tower meets all of the above-mentioned conditions for starting feeding, then the adsorption tower is determined to meet the conditions for starting feeding.

[0075] Furthermore, in one embodiment of the present invention, the method of providing nitrogen protection to the upper packing tank until the nitrogen pressure reaches the set pressure value may include the following steps:

[0076] S321, close the feed valve of the upper packing tank and output a closed signal;

[0077] S322, close the feed valve of the lower packing tank and output a closed signal;

[0078] S323, open the nitrogen charging valve, the pressure in the upper packing tank gradually increases until it reaches the pressure set value, then the nitrogen charging valve closes.

[0079] In one embodiment of the present invention, the pressure setting value can be set as needed. For example, the pressure setting value is 4 kPa.

[0080] Furthermore, in one embodiment of the present invention, the method of replenishing the adsorbent in the upper packing tank to the lower packing tank of the adsorption tower until it flows by gravity into the adsorption tower to complete the distribution of the adsorbent in the adsorption tower may include: opening the feed valve of the lower packing tank to replenish the adsorbent in the upper packing tank to the lower packing tank of the adsorption tower until the adsorbent in the upper packing tank flows into the lower packing tank to complete the distribution of the adsorbent in the adsorption tower.

[0081] In one embodiment of the present invention, the above steps can be used to distribute adsorbent to a certain adsorption tower or a certain column of adsorption towers, and the method for distributing adsorbent to other remaining adsorption towers or columns of adsorption towers is the same as the above method.

[0082] Furthermore, in one embodiment of the present invention, the above method may further include: in response to a low material level alarm occurring in the lower packing tank of the target adsorption tower among a plurality of adsorption towers, immediately distributing adsorbent to the target adsorption tower until the target adsorption tower has been completely distributed, and then distributing adsorbent to the other adsorption towers among the plurality of adsorption towers in sequence.

[0083] For example, in one embodiment of the present invention, if the high material level alarm occurs in all packing materials of the fourth adsorption tower, it indicates that there is too much adsorbent in the adsorption tower and no replenishment is needed. Then, the third and second chain bucket machines stop running, and the double swirl of the regeneration tower stops running. After the high material level in a certain column disappears, the adsorption tower replenishment process is resumed after a delay of 120 seconds.

[0084] In one embodiment of the present invention, a first bucket elevator transports the adsorbent discharged from multiple adsorption towers to a regeneration tower; a second bucket elevator transports the adsorbent discharged from the regeneration tower to a third bucket elevator; and the third bucket elevator distributes the adsorbent to the multiple adsorption towers. Thus, the adsorbent from multiple adsorption towers and regeneration towers can be transported and distributed using the first, second, and third bucket elevators, thereby achieving material balance and automatic control operation between the adsorption towers and regeneration towers.

[0088] The distribution module 303 is used to distribute adsorbent to multiple adsorption towers via a third chain bucket elevator.

[0089] In one embodiment of the present invention, the above-described apparatus is further configured to:

[0090] In response to a high material level alarm in the regeneration tower, the adsorption tower discharge double swirl stops operating, the first chain bucket machine stops, the regeneration tower feed double swirl stops, and after a preset delay after the high material level signal in the regeneration tower disappears, the regeneration tower feed double swirl, the first chain bucket machine, and multiple adsorption tower discharge double swirls are started in sequence.

[0091] In response to a low material level alarm in the regeneration tower, the regeneration tower discharge rotary valve stops operating. After a preset delay after the low material level signal disappears, the regeneration tower discharge rotary valve resumes operation.

[0092] Furthermore, in one embodiment of the present invention, the allocation module 303 is specifically used for:

[0093] The third chain bucket elevator feeds the upper packing tank of the adsorption tower until the upper packing tank is full;

[0094] Nitrogen protection is applied to the upper packing tank until the nitrogen pressure reaches the set pressure value;

[0095] The adsorbent in the upper packing tank is replenished to the lower packing tank of the adsorption tower until it flows by gravity into the adsorption tower, thus completing the distribution of the adsorbent in the adsorption tower.

[0096] Furthermore, in one embodiment of the present invention, the allocation module 303 is further configured to:

[0098] If the adsorption tower meets the conditions for starting feeding, the third chain bucket elevator will activate the discharge baffle to feed the adsorption tower until the upper packing tank reaches a high level or the level radar alarms, at which point the discharge baffle will be closed and the upper packing tank will be filled.

[0099] Furthermore, in one embodiment of the present invention, activating the feeding conditions includes:
