Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically, to a coke treatment device for an adsorption tower. Background Art

[0002] Activated coke is a carbon material with a relatively developed pore structure, a large specific surface area, and good adsorption performance. With the increasing demand for sewage or wastewater treatment, the use of activated coke materials for wastewater treatment or urban sewage treatment is becoming more and more common. Activated coke particles themselves have two functions: adsorption and filtration. Soluble and colloidal pollutants in the raw water are adsorbed by activated coke, and suspended matter in the raw water is also trapped and filtered in the pore structure inside the activated coke particles. Therefore, it is necessary to extract the activated coke particles from the treatment tank or adsorption tower in order to meet the requirements of subsequent processes for cleaning the granular activated coke to restore its activity.

[0003] In addition, during the use of the granular activated coke, it is also necessary to turn the granular activated coke over so that the granular activated coke at the bottom can be moved up and evenly re-laid on the bottom of the adsorption tower. In this way, the pore utilization rate of the granular activated coke can be increased to the greatest extent, and the granular activated coke can evenly reach the saturated adsorption state.

[0004] Therefore, the problems existing in the prior art need to be further improved and developed. Summary of the invention

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with preferred embodiments. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0022] The accompanying drawings are schematic diagrams of embodiments of the present invention. It should be noted that the drawings are only examples and are not drawn to scale, and should not be used to limit the actual protection scope of the present invention.

[0023] A coke treatment device for an adsorption tower, see Figure 1As shown, an air pipe 1, a lifting pipe 2, a layer turning structure 3, and a coke washing pipe 5 are sequentially arranged in a direction away from the bottom of the adsorption tower. A material dropping pipe 4 is arranged on the side of the layer turning structure 3 connected to the lifting pipe 2, and a control valve 6 is arranged on the coke washing pipe 5. The air pipe 1 is located at the bottom of the adsorption tower, and extends into the interior of the lifting pipe 2 at one end close to the lifting pipe 2. Compressed air is introduced into the other end of the air pipe 1, and the compressed air causes the activated coke particles to be lifted inside the lifting pipe 2. The principle is: since the density of the activated coke particles is less than the density of water, when the compressed air is input into the bottom of the lifting pipe 2 through the air pipe 1, the density in the lifting pipe 2 is less than the density outside the pipe. According to the principle of liquid balance, the liquid level of the mixture with a relatively small density is higher. Under the combined effect of the suction force formed by the rising mixture in the pipe and the pressure outside the pipe, the activated coke particles continuously flow in from the bottom of the lifting pipe 2, thereby causing the activated coke particles to be lifted inside the lifting pipe 2. The lifting pipe 2 is located inside the adsorption tower, extends downward into the active coke particle layer, and extends toward the end of the bottom of the adsorption tower close to the ground, providing an ascending channel for the active coke particles. The layer turning structure 3 allows the active coke that needs to be turned over to re-enter the inside of the adsorption tower in the designated area, so as to achieve the effect of turning the active coke particles to the designated area. The end of the layer turning structure 3 close to the bottom of the adsorption tower is connected to the lifting pipe 2, and the end away from the bottom of the adsorption tower is connected to the coke washing pipe 5. The blanking pipe 4 is connected to the layer turning structure 3, located at the end close to the bottom of the adsorption tower, and is arranged parallel to the lifting pipe 2, so as to send the lifted active coke particles into the designated area for layer turning. The coke washing pipe 5 is connected to the layer turning structure 3 at one end of the layer turning structure 3 away from the ground, and the other end is connected to the coke washing equipment. The control valve 6 is located on the vertical section of the coke washing pipe 5 away from the ground, and is used to control whether the lifted active coke particles are washed.

[0024] Among them, the lifting pipe 2 is provided with a lifting cover at one end close to the bottom of the adsorption tower. The lifting cover is a truncated cone cover, and its diameter gradually shrinks near the end of the turning layer structure 3 to increase the lifting area of ​​the activated coke particles.

[0025] See also Figure 2As shown, the layer turning structure 3 includes a layer turning cylinder 31, a control panel 32, and a driving member 33. The end of the layer turning cylinder 31 away from the ground is connected to the coke washing pipe 5. When the control valve 6 is closed, the layer turning cylinder 31 can allow the active coke particles lifted by the lifting pipeline 2 to enter the inside of the layer turning cylinder 31 under the action of compressed air. The control panel 32 is installed on the layer turning cylinder 31 at the end of the layer turning cylinder 31 close to the ground and rotates relative to the bottom of the layer turning cylinder 31. Under the action of the driving member 33, the control panel 32 selects the area where the active coke inside the layer turning cylinder 31 returns to the inside of the adsorption tower. The driving member 33 is installed on the outer wall of one side of the layer turning cylinder 31 to drive the control panel 32 to rotate, thereby causing the active coke inside the layer turning cylinder 31 to fall into the corresponding area of ​​the adsorption tower through the drop pipe 4.

[0026] More specifically, the layer turning cylinder 31 is a cylindrical body, and a first pipe 311 is arranged at the top of the layer turning cylinder 31, at one end away from the ground; a second pipe 312 is arranged at the bottom of the layer turning cylinder 31, at one end close to the ground. At the bottom of the layer turning cylinder 31, drop holes 313 are evenly arranged around the second pipe 312.

[0027] The first pipe 311 is connected to the coke washing pipe 5, and the second pipe 312 extends toward the ground and passes through the pipe hole 322 of the control panel 32 to be connected to the lifting pipe 2. The number of the drop holes 313 is not limited. In the present invention, preferably, four drop holes 313 are provided. That is, the area with the lifting pipe 2 as the center at the bottom of the adsorption tower is divided into four partitions. Each partition corresponds to one drop hole 313.

[0028] The control plate 32 is a circular gear plate, and meshing teeth are arranged on the outer circumference of the control plate 32. A pipe hole 322 is arranged at the center of the control plate 32, and a feeding hole 321 is arranged on the control plate 32 and at a position away from the pipe hole 322. The pipe hole 322 is in a straight line with the central axis of the second pipe 312 and the first pipe 311, and the diameter of the pipe hole 322 is larger than the diameter of the second pipe 312, so that the second pipe 312 can be smoothly inserted, so that the control plate 32 is sleeved on the second pipe 312 of the layer turning cylinder 31 and rotated around the central axis of the second pipe 312. The feeding hole 321 is connected to the drop pipe 4 at one end close to the ground, and is connected to the internal space of the drop pipe 4. The diameter of the feeding hole 321 is larger than or equal to the diameter of the drop hole 313, so that the granular activated coke can smoothly fall out of the inside of the layer turning cylinder 31.

[0029] Specifically, when the feed hole 321 rotates to partially or completely overlap with one of the drop holes 313, the granular activated coke is discharged from the inside of the layer turning cylinder 31 to the corresponding partition; when the feed hole 321 is staggered with all the drop holes 313, the granular activated coke cannot be discharged from the layer turning cylinder 31, and the granular activated coke is extracted to the coke washing equipment under the action of air pressure when the control valve 6 is opened.

[0030] The driving member 33 includes a driving motor 331, a fixing plate 332, a rotating shaft 333, and a driving wheel 334. The fixing plate 332 is fixed to an outer wall of one side of the layer turning cylinder 31. The driving motor 331 is arranged at an end of the fixing plate 332 away from the ground. The rotating shaft 333 passes through the fixing plate 332, and one end is connected to the driving motor 331, and the other end is connected to the driving wheel 334. The driving wheel 334 is meshed with the control board 32 for transmission.

[0031] The specific process of the coke extraction and processing device for an adsorption tower is as follows: when the active coke particles inside the adsorption tower need to be turned over, the controlled valve 6 is closed. At the same time, under the drive of the drive motor 331, the control panel 32 rotates an angle, selects the partition that needs to be turned over, and makes the feeding hole 321 partially or completely overlap with one of the drop holes 313, so that the active coke particles fall out of the drop hole 313 and pass through the feeding hole 321, and enter the outer peripheral partition of the lifting pipeline 2 from the drop pipe 4. When the active coke particles need to be washed, the control valve 6 is opened, and the drive motor 331 makes the control panel 32 close the layer turning cylinder 31, that is, the feeding hole 321 and the drop hole 313 are staggered. Under the action of air pressure, the active coke particles are discharged from the first pipeline 311 to the layer turning cylinder 31 and enter the coke washing pipe 5 connected to the coke washing equipment, so that the particle active coke is extracted to the coke washing equipment.

[0032] The utility model discloses a coke processing device for an adsorption tower. By arranging a layer turning structure, not only can the layers of activated coke particles inside the adsorption tower be turned over, but also the area where the layer turning is required can be selected, thereby improving the pore utilization rate of the particle activated coke and saving labor costs.
