Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment devices, in particular to a flue gas treatment device for an activated carbon carbonization process. Background Art

[0002] The activated carbon carbonization process is a process of converting raw materials into activated carbon through the carbonization process. This process is usually carried out in a carbonization furnace. During the carbonization process in the carbonization furnace, high temperature is required for heating and distillation. This process will produce a large amount of flue gas. In order to avoid flue gas pollution to the environment, a flue gas treatment device is usually required to treat the flue gas discharged from the carbonization furnace.

[0003] Prior art (publication number: CN212262751U) "The present utility model provides a flue gas treatment system for the carbonization process of producing activated carbon, characterized in that the structure includes: a carbonization furnace; a water film dust removal device arranged behind the carbonization furnace; an electrostatic dust removal device arranged behind the water film dust removal device, including: a discharge electrode plate and a dust collecting electrode plate installed at intervals inside the box of the electrostatic dust removal device, a water mist spray plate arranged above the dust collecting electrode plate of the box, a dust collecting port arranged at the bottom of the electrostatic dust removal device; an exhaust gas treatment device arranged behind the electrostatic dust removal device. The beneficial effects of the present utility model are: a water film dust removal device is provided to remove smoke dust with larger particle sizes in the dust and cool the high-temperature flue gas; an electrostatic dust removal device is provided to cool the high-temperature flue gas and remove smoke dust of different particle sizes in the flue gas; a water mist spray plate is provided in the electrostatic dust removal device to facilitate the introduction of polluted dust into the wastewater circulation system and purify the smoke dust."

[0004] When treating the flue gas, it uses discharge plates and dust collecting plates to attach some of the substances in the flue gas to the surface of the dust collecting plates. However, when cleaning the dust on the surface of the dust collecting plates, it uses water mist spray plates to spray the dust collecting plates, which is relatively unsafe.

[0005] Therefore, those skilled in the art provide a flue gas treatment device for an activated carbon carbonization process to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a flue gas treatment device of an activated carbon carbonization process is proposed. The surface of the dust collecting plate is cleaned by arranging bristles, which is safer. The auger provides a backward force to the water inside the treatment box, so that the cleaned dust is mixed with the water and flows from the slow flow plate to the inside of the water collecting box. There is no need for manual cleaning of the collected dust, which is more convenient.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a flue gas treatment device for an activated carbon carbonization process, comprising a water collecting box, a water flow plate, three atomizing nozzles, an auger, a motor, multiple cleaning mechanisms, a rotating mechanism, a guide plate, and a first magnetic strip, wherein the upper end surface of the water collecting box is fixedly provided with a treatment box, a slow flow plate is embedded in the rear side of the bottom surface of the treatment box, a plurality of discharge electrode plates are fixedly provided on the inner wall of the front side of the treatment box, a plurality of dust collecting electrode plates are fixedly provided on the side of the inner wall of the front side of the treatment box close to the discharge electrode plates, a pulley is fixedly provided on the front end of the auger and the front end of the rotating mechanism, and a belt is provided between the two pulleys;

[0008] The multiple cleaning mechanisms include multiple fixed plates, multiple lifting plates and multiple ropes. Multiple bristles are fixedly provided on the end faces of both sides of the multiple lifting plates. The rotating mechanism includes two support plates and a rotating column. A second magnetic strip is embedded on one side of the outer end face of the rotating column.

[0009] Furthermore, the water-passing plate is embedded in the middle position of the rear side of the upper end surface of the processing box, and the three atomizing nozzles are all embedded in the lower end surface of the water-passing plate.

[0010] Furthermore, the auger is rotatably arranged between the front and rear inner walls of the processing box and at a lower position, the motor is fixedly arranged on the lower side of the rear end surface of the processing box, and the output end of the motor is fixedly connected to the rear end of the auger.

[0011] Furthermore, the guide plate is fixedly arranged at a side position in front of the upper end face of the processing box, and the first magnetic strip is slidably arranged inside the guide plate.

[0012] Furthermore, the plurality of fixed plates are fixedly arranged at the front side of the top surface of the processing box, and the plurality of lifting plates are slidably arranged at the lower side between the inner walls on both sides of the plurality of fixed plates.

[0013] Furthermore, the lower ends of the multiple ropes are fixedly connected to the multiple lifting plates respectively, and the upper ends of the multiple ropes are fixedly connected to the rear end of the first magnetic strip through claw-shaped ropes.

[0014] Furthermore, the two support plates are both fixedly connected to the front side of the upper end of the processing box, and the rotating column is rotatably arranged between the two support plates.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model proposes a flue gas treatment device of an activated carbon carbonization process, which sprays water into the treatment box through an atomizing nozzle, so that a part of the substances in the flue gas are mixed with the atomized water, and finally mixed with the water inside the treatment box, and the auger is driven by a motor to rotate clockwise, so that the water inside the treatment box has a force to flow backward. At this time, the dust cleaned from the surface of the dust collecting plate is mixed with the water, and moves backward together, and finally flows from the conical hole opened in the slow flow plate to the inside of the water collecting box. The water containing substances and dust can be pumped out through an external pipe, and there is no need to manually clean the dust, which is more convenient.

[0017] 2. The utility model proposes a flue gas treatment device for an activated carbon carbonization process. The flue gas that has been preliminarily treated enters the front end of the post-treatment box. At this time, under the action of the discharge electrode plate and the dust collecting electrode plate, a part of the substances in the flue gas adheres to the surface of the dust collecting electrode plate, so that the flue gas can be further treated. In the treatment process, since the auger drives the rotating column to rotate through the belt, the rotating column can drive multiple lifting plates to move upward through the magnetic connection between the first magnetic strip and the second magnetic strip during the rotation process. By arranging bristles on the surface of the lifting plate, the surface of the dust collecting plate can be cleaned, which is safer than cleaning the dust collecting plate with atomized water.

[0028] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The utility model provides an embodiment: a flue gas treatment device for an activated carbon carbonization process, comprising a water collecting box 1, a water passing plate 3, three atomizing nozzles 4, an auger 5, a motor 6, a plurality of cleaning mechanisms 8, a rotating mechanism 9, a guide plate 12 and a first magnetic strip 13. A treatment box 2 is fixedly arranged on the upper end surface of the water collecting box 1, a slow flow plate 7 is embedded in the rear side of the inner bottom surface of the treatment box 2, a plurality of discharge electrode plates 10 are fixedly arranged on the front inner wall of the treatment box 2, a plurality of dust collecting plates 11 are fixedly arranged on the side of the front inner wall of the treatment box 2 near the discharge electrode plate 10, the water passing plate 3 is embedded in the middle position at the rear side of the upper end surface of the treatment box 2, the three atomizing nozzles 4 are all embedded in the lower end surface of the water passing plate 3, the auger 5 is rotatably arranged between the front and rear inner walls of the treatment box 2, the motor 6 is fixedly arranged on the lower side of the rear end surface of the treatment box 2, and the output end of the motor 6 is fixedly connected to the rear end of the auger 5.

[0030] Specifically, by connecting the air inlet at the rear end of the treatment box 2 with the exhaust port of the carbonization furnace, the flue gas inside the carbonization furnace enters the treatment box 2. After entering, the cold water can be sprayed into the treatment box 2 through the water inlet pipe connected to the water-passing plate 3. After spraying, the atomized cold water contacts the flue gas, thereby cooling the flue gas, and mixing part of the substances in the flue gas with the atomized water, and finally mixing with the water inside the treatment box 2. By setting the slow flow plate 7, the water in the treatment box 2 enters the interior of the water collecting tank 1. By spraying water from the upper end of the treatment box 2 and discharging water from the lower end of the treatment box 2, the water in the treatment box 2 can be kept in a relatively clean state, and will not reach saturation when mixed with the substance.

[0031] And when the flue gas that has undergone preliminary treatment enters the front end of the treatment box 2, part of the substances in the flue gas can be adsorbed on the surface of the dust collecting plate 11 through the action of the discharge electrode plate 10 and the dust collecting plate 11. When the surface of the dust collecting plate 11 is cleaned by the cleaning mechanism 8, the dust cleaned down is stirred by the auger 5 to mix the dust with water, and finally flows into the water collecting box 1. At this time, the water in the water collecting box 1 can be pumped out through the external pipe of the water collecting box 1. By connecting the front end of the treatment box 2 to a desulfurization tower and a denitrification tower, the flue gas can be subsequently treated.

[0032] Reference Figure 4 、 Figure 7 and Figure 8 , pulleys 14 are fixedly provided at the front end of the auger 5 and the front end of the rotating mechanism 9, and a belt 15 is provided between the two pulleys 14. The rotating mechanism 9 includes two support plates 901 and a rotating column 902. A second magnetic strip 903 is embedded on one side of the outer end face of the rotating column 902. The guide plate 12 is fixedly provided at a position on one side of the front side of the upper end face of the processing box 2. The first magnetic strip 13 is slidably provided inside the guide plate 12. The two support plates 901 are fixedly connected to the front side of the upper end of the processing box 2, and the rotating column 902 is rotatably provided between the two support plates 901.

[0033] Specifically, when the auger 5 rotates, by setting two pulleys 14 and a belt 15, the rotating column 902 can be driven to rotate together. When the rotating column 902 rotates, the second magnetic strip 903 embedded in the rotating column 902 is driven to rotate together. The first magnetic strip 13 is magnetically connected to the second magnetic strip 903, which can drive the first magnetic strip 13 to rotate inside the guide plate 12. When the first magnetic strip 13 rotates to the tail, it is blocked by the guide plate 12. At this time, the rotating column 902 continues to rotate, thereby separating the first magnetic strip 13 from the second magnetic strip 903. The first magnetic strip 13 is pulled back to its original position by the gravity of multiple cleaning mechanisms 8. When the second magnetic strip 903 returns to its original position, the first magnetic strip 13 and the second magnetic strip 903 are reconnected together, which can drive the first magnetic strip 13 to reciprocate inside the guide plate 12.

[0034] Reference Figure 2 、 Figure 4 and Figure 6 The multiple cleaning mechanisms 8 include multiple fixed plates 801, multiple lifting plates 802 and multiple ropes 804. Multiple bristles 803 are fixedly set on the end surfaces of both sides of the multiple lifting plates 802. The multiple fixed plates 801 are fixedly set at the front side of the top surface of the processing box 2. The multiple lifting plates 802 are respectively slidably set on the lower side between the inner walls on both sides of the multiple fixed plates 801. The lower ends of the multiple ropes 804 are respectively fixedly connected to the multiple lifting plates 802, and the upper ends of the multiple ropes 804 are fixedly connected to the rear end of the first magnetic strip 13 through claw-shaped ropes.

[0035] Specifically, when the first magnetic strip 13 rotates inside the guide plate 12, the guide plate 12 pulls the multiple ropes 804 through the claw-shaped rope, which can drive the lifting plate 802 to move upward. During the movement, the surface of the dust collecting plate 11 can be cleaned by the bristles 803 set on the surface of the lifting plate 802. The first magnetic strip 13 can perform reciprocating motion, which can drive the lifting plate 802 to perform reciprocating motion together, so that the surface of the dust collecting plate 11 is always in a clean state, thereby improving the adsorption effect of flue gas substances, and the surface of the dust collecting plate 11 is cleaned by the bristles 803, which is safer.

[0036] Working principle: By connecting the rear end of the treatment box 2 with the exhaust port of the carbonization furnace, and connecting the front end of the treatment box 2 with the desulfurization tower and the denitrification tower, and finally connecting the water-passing plate 3 and the water collecting box 1 with the water inlet pipe and the water outlet pipe respectively, after the preparation work is done, the flue gas can be introduced into the treatment box 2, and atomized cooling water is sprayed out through the atomizing nozzle 4, so that part of the substances in the flue gas are mixed with the atomized water and flow out to the lower end of the treatment box 2. Then the flue gas that has undergone preliminary treatment enters the front end of the treatment box 2. Through the action of the discharge electrode plate 10 and the dust collecting electrode plate 11, part of the substances in the flue gas can be adsorbed onto the surface of the dust collecting electrode plate 11. Finally, the flue gas flows out of the treatment box 2 and flows into the desulfurization tower and the denitrification tower. During the treatment process, the motor 6 drives the auger 5 and the rotating column 902 to rotate together, so that the dust on the surface of the dust collecting electrode plate 11 can be mixed with the water in the treatment box 2, and flow through the slow flow plate 7 to the inside of the water collecting box 1, and finally the water containing the substances is extracted from the water collecting box 1.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
