Abstract
Description
Technical Field
[0001] This utility model relates to the field of activated carbon production technology, specifically to a cooling water circulation device for activated carbon production. Background Technology
[0002] Activated carbon production is an industrial process that transforms carbon-rich raw materials into substances with extremely high adsorption properties. Through physical or chemical methods, an extremely well-developed pore structure is created in the raw materials, giving them a huge specific surface area, which enables them to adsorb various substances.
[0003] In the activated carbon production process, the finished product needs to be sprayed with cooling water to achieve rapid cooling. The common method is to let the cooling water after spraying flow into the collection tank for temporary storage. After it cools naturally or is forcibly cooled by a chiller, it is pumped back to the spraying system for recycling. However, activated carbon particles mixed in the return water can easily cause the spray head to be blocked, affecting the stable operation of the system. At the same time, a large amount of waste heat carried by the spray water is not effectively utilized in the collection tank, which is only forcibly cooled by the chiller, resulting in a waste of heat energy. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a cooling water circulation device for activated carbon production, comprising a filtration mechanism, one end of which is equipped with a heat exchange mechanism. The filtration mechanism includes a filter tank, the interior of which is equipped with a filtration structure for intercepting activated carbon particles. High-temperature return water is purified by the filtration structure and then output. The heat exchange mechanism includes a collection box, the interior of which is equipped with a partition plate that divides the interior of the collection box into an upper chamber and a lower chamber. A heat exchange tube is provided at the upper end of the partition plate, and the inlet and outlet of the heat exchange tube both penetrate the partition plate and are connected to an external pipeline. The high-temperature return water purified by the filtration mechanism flows into the upper chamber and then flows into the lower chamber through an opening in the partition plate. A movable sealing block is provided at the opening.
[0006] Furthermore, the filter tank includes an upper shell and a lower shell, and an annular groove is provided at the connection between the upper shell and the lower shell. The filter structure includes a ring body rotatably connected in the annular groove. An upper cylinder is provided at the upper end of the ring body, and a lower cylinder is provided at the lower end of the ring body. Multiple filter holes are provided on the outer side of the lower cylinder. A first motor is installed at the upper end of the upper shell. The output shaft of the first motor is connected to the upper cylinder through a coupling to drive the filter structure to rotate.
[0007] Furthermore, the upper end of the ring body is provided with multiple water inlets, the outer side of the upper shell is connected to a water inlet pipe and a drain pipe, the other end of the drain pipe is connected to a U-shaped pipe, one end of the U-shaped pipe is connected to the upper chamber of the collection box through a connecting pipe, and the lower end of the lower shell is connected to a sewage discharge pipe.
[0008] Furthermore, the lower end of the sealing block is provided with a groove, and the outer side of the sealing block is provided with a plurality of drainage holes communicating with the groove. The inside of the collection box is rotatably connected to a rotating shaft, and a connecting block is fixedly installed on the outer side of the rotating shaft. The other end of the connecting block is hinged to a connecting plate, and the other end of the connecting plate is hinged to the upper end of the sealing block. One end of the rotating shaft passes through the collection box and is connected to a second motor that drives its rotation.
[0009] Furthermore, a first synchronous pulley is installed at one end of the rotating shaft, and a second synchronous pulley is installed at the output end of the second motor. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt.
[0010] Furthermore, the heat exchange tubes are arranged in a circuitous manner at the upper end of the partition plate.
[0011] Furthermore, a return pipe is connected to the outside of the collection box, and an inclined surface is provided at the bottom of the inner side of the collection box, with the return pipe located at the lowest end of the inclined surface.
[0012] Furthermore, control valves are installed on the outer sides of both ends of the water inlet pipe, sewage pipe, return pipe, and U-shaped pipe.
[0013] This utility model has the following beneficial effects: (1) By opening the control valves on the inlet pipe, U-shaped pipe and connecting pipe, the high-temperature return water enters the inner cavity of the upper shell through the inlet pipe. At this time, the pipe on the outside of the upper cylinder is aligned with the outlet of the inlet pipe. The high-temperature return water enters the interior of the continuously rotating upper cylinder through the guide of the pipe and falls into the lower cylinder under the action of gravity. The water accumulates in the lower cylinder and is filtered through the filter holes opened on its side wall. The activated carbon particles are intercepted and retained in the lower cylinder, while the purified water flows into the inner cavity of the lower shell through the filter holes. Subsequently, the purified water flows upward through the inlet opened at the upper end of the ring and re-enters the inner cavity of the upper shell, and is discharged through the drain pipe. After that, the water flows through the U-shaped pipe and connecting pipe in sequence and is finally transported. In the upper chamber of the collection tank, the sealing block falls under gravity, sealing the opening on the partition plate. The high-temperature return water remains in the upper chamber and exchanges heat with the cold medium in the heat exchange tube. When the heat exchange is complete and drainage is required, the second motor is started. The second motor drives the shaft to rotate via a synchronous belt drive. The connecting block on the shaft rotates with the shaft, pushing the connecting plate hinged to it to move. The connecting plate lifts the sealing block upward, causing it to rise vertically within the opening. As the sealing block rises, the drain hole on its side wall and the groove at its lower end are gradually exposed and connected to the lower chamber. The cooled water then flows into the lower chamber through this path. Finally, the cooling water is collected under the guidance of the inclined surface at the bottom of the collection tank and is pumped back by an external water pump through the return pipe, completing the circulation.
[0014] (2) By starting the first motor, the output shaft of the present invention drives the upper cylinder and the entire filter structure to rotate 180°. This rotational movement makes the tube fixed on the outside of the upper cylinder aligned with the inlet of the drain pipe, thus completing the flow path switching. The cleaning liquid provided by the external high-pressure pump is injected through the U-shaped tube 16 under pressure and is pushed back into the aligned tube through the drain pipe. The high-pressure cleaning liquid then rushes into the upper cylinder 1 and strongly impacts the inner cavity of the lower cylinder. The high-pressure fluid penetrates the filter holes on the side wall of the lower cylinder from the inside out, forming a strong reverse flushing force on the activated carbon particles that are blocked on the inner wall of the filter holes and attached to the inside of the lower cylinder, completely peeling and dispersing them. The waste cleaning liquid carrying the flushed impurities is continuously discharged through the opened drain pipe until the filter holes of the lower cylinder are completely cleaned, thus achieving the flushing effect on the filter structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] like Figures 1-4 As shown, this embodiment discloses an implementation method for high-temperature reflux water filtration and heat exchange: This utility model is a cooling water circulation device for activated carbon production, including a filtration mechanism. One end of the filtration mechanism is provided with a heat exchange mechanism. The filtration mechanism includes a filter tank 11. The filter tank 11 is provided with a filter structure for intercepting activated carbon particles. High-temperature return water is purified by the filter structure and then output. The heat exchange mechanism includes a collection box 21. A partition plate 22 is installed inside the collection box 21. The partition plate 22 divides the inside of the collection box 21 into an upper chamber 2101 and a lower chamber 2102. A heat exchange tube 23 is provided at the upper end of the partition plate 22. The inlet and outlet of the heat exchange tube 23 both pass through the partition plate 22 and are connected to external pipelines. The high-temperature return water purified by the filtration mechanism flows into the upper chamber 2101 and flows into the lower chamber 2102 through a through-hole 2201 opened on the partition plate 22. A movable sealing block 24 is provided at the through-hole 2201. The inlet of the heat exchange tube 23 is connected to the external cold source water supply pipe, and the outlet of the heat exchange tube 23 is connected to the waste heat utilization system pipe to realize heat energy recovery. The filter tank 11 includes an upper shell 1101 and a lower shell 1102. An annular groove is provided at the connection between the upper shell 1101 and the lower shell 1102. The filter structure includes an annular body 1201 rotatably connected in the annular groove. An upper cylinder 1202 is provided at the upper end of the annular body 1201, and a lower cylinder 1203 is provided at the lower end of the annular body 1201. Multiple filter holes are provided on the outer side of the lower cylinder 1203. The outer side of the upper cylinder 1202 is connected to a pipe, which is connected to the inlet pipe 14 when filtering back water. The upper end of the ring 1201 is provided with multiple water inlets. The outer side of the upper shell 1101 is connected to the water inlet pipe 14 and the drain pipe 15. The other end of the drain pipe 15 is connected to the U-shaped pipe 16. One end of the U-shaped pipe 16 is connected to the upper chamber 2101 of the collection box 21 through the connecting pipe 3. The lower end of the lower shell 1102 is connected to the sewage pipe 17. The inlet pipe 14 is connected to an external high-temperature return water conveying pipe to introduce high-temperature cooling return water from the activated carbon to be treated. The lower end of the sealing block 24 is provided with a groove, and the outer side of the sealing block 24 is provided with multiple drainage holes that communicate with the groove. The inside of the collection box 21 is rotatably connected to a rotating shaft 25. A connecting block 26 is fixedly installed on the outer side of the rotating shaft 25. The other end of the connecting block 26 is hinged to a connecting plate 27. The other end of the connecting plate 27 is hinged to the upper end of the sealing block 24. One end of the rotating shaft 25 passes through the collection box 21 and is connected to a second motor 4 that drives its rotation. Among them, the second motor 4 drives the rotating shaft 25 to rotate, which in turn drives the sealing block 24 to rise and fall via the connecting block 26 and the connecting plate 27; A first synchronous pulley 5 is installed at one end of the rotating shaft 25, and a second synchronous pulley 6 is installed at the output end of the second motor 4. The first synchronous pulley 5 and the second synchronous pulley 6 are connected by a synchronous belt 7. Among them, power transmission is achieved through synchronous belt 7, ensuring stable rotation speed of shaft 25; The outside of the collection box 21 is connected to the return pipe 28, and the bottom of the collection box 21 is provided with an inclined surface, with the return pipe 28 located at the lowest end of the inclined surface. The inclined surface design facilitates the collection of cooling water and ensures thorough drainage. Specifically, during the filtration process, the control valve 8 on the inlet pipe 14, U-shaped pipe 16 and connecting pipe 3 is opened, and the high-temperature return water enters the inner cavity of the upper shell 1101 through the inlet pipe 14. At this time, the pipe on the outside of the upper cylinder 1202 is aligned with the outlet of the inlet pipe 14. The high-temperature return water enters the interior of the continuously slowly rotating upper cylinder 1202 through the guide of the pipe and falls down into the lower cylinder 1203 under the action of gravity. Water accumulates in the lower cylinder 1203 and is filtered through the filter holes on its side wall. Activated carbon particles are intercepted and retained inside the lower cylinder 1203, while the purified water flows through the filter holes into the inner cavity of the lower shell 1102. Subsequently, the purified water flows upward through the water inlet at the upper end of the ring 1201, re-enters the inner cavity of the upper shell 1101, and is discharged through the drain pipe 15. After that, the water flows through the U-shaped pipe 16 and the connecting pipe 3 in sequence, and is finally transported to the upper chamber 2101 of the collection box 21. At this stage, the sealing block 24 falls under the action of gravity, sealing the opening 2201 on the partition plate 22. The high temperature return water is retained in the upper chamber 2101 and exchanges heat with the cold medium in the heat exchange tube 23. When the heat exchange is complete and drainage is required, the second motor 4 is started. The second motor 4 drives the rotating shaft 25 to rotate via the synchronous belt 7. The connecting block 26 on the rotating shaft 25 rotates with the shaft, pushing the connecting plate 27 hinged to it to move. The connecting plate 27 lifts the sealing block 24 upward, causing it to rise vertically within the opening 2201. As the sealing block 24 rises, the drain hole on its side wall and the groove at its lower end are gradually exposed and connected to the lower chamber 2102. The cooled water then flows into the lower chamber 2102 through this path. Finally, the cooling water is collected under the guidance of the inclined surface at the bottom of the collection tank 21 and is pumped back by the external water pump through the return pipe 28, completing the circulation.
[0020] like Figure 5 As shown, this embodiment discloses an implementation method for backwashing the filter structure: A first motor 13 is installed at the upper end of the upper housing 1101, and the output shaft of the first motor 13 is connected to the upper cylinder 1202 via a coupling. During reverse cleaning, the upper cylinder 1202 is rotated 180° to connect the pipe body with the drain pipe 15. Among them, the connection switching of the pipe body under different working conditions is achieved by rotating the upper cylinder 1202; The other end of the U-shaped pipe 16 is connected to the external cleaning fluid supply pipe, and the drain pipe 17 is connected to the external wastewater collection pipe. The cleaning solution is connected through the U-shaped pipe 16, and the wastewater is discharged through the drain pipe 17. Specifically, when it is necessary to perform high-pressure backwashing on the filter structure, first close the control valve 8 on the inlet pipe 14 and the connecting pipe 3 to block the normal filtration path. Then, open the control valve 8 on the U-shaped pipe 16 and the external high-pressure cleaning fluid supply pipeline, as well as the control valve 8 on the drain pipe 17. The first motor 13 is started, and its output shaft drives the upper cylinder 1202 and the entire filter structure to rotate 180°. This rotation causes the pipe fixed on the outside of the upper cylinder 1202 to align with the inlet of the drain pipe 15, thus completing the flow path switching. Under pressure, the cleaning fluid supplied by the external high-pressure pump is injected through the U-shaped tube 16 and then pushed back into the aligned tube body through the drain pipe 15. The high-pressure cleaning fluid then rushes into the upper cylinder 1202 and forcefully impacts the inner cavity of the lower cylinder 1203. The high-pressure fluid penetrates the filter holes on the side wall of the lower cylinder 1203 from the inside out, forming a strong reverse flushing force on the activated carbon particles and impurities that are blocked on the inner wall of the filter holes and attached to the inside of the lower cylinder 1203, completely peeling and dispersing them. The waste cleaning fluid, carrying the flushed impurities, is continuously discharged through the opened drain pipe 17 until the filter holes of the lower cylinder 1203 are completely cleaned.
