Description

Technical Field

[0001] This utility model relates to the field of activated coke drying technology, specifically a regenerated activated coke drying device. Background Technology

[0002] Regenerated activated coke refers to the regeneration process of activated coke that has become saturated with adsorption and lost its adsorption capacity, in order to restore its adsorption performance and achieve reuse. The regeneration process mainly includes drying, carbonization, and activation. The drying stage involves heating the water-containing activated coke to evaporate the adsorbed water within the carbon particles, and some low-boiling-point organic compounds also volatilize at the same time.

[0003] Patent CN221005853U discloses a method for drying regenerated activated coke using activated waste gas to achieve energy saving. The water vapor generated during the drying process needs to be extracted through a water vapor pipe. Although this method can achieve the recovery and utilization of water vapor, the vent holes on the surface of the water vapor pipe are easily blocked by activated coke powder, particles and impurities during use, which affects the emission of water vapor and reduces the drying effect. Utility Model Content

[0004] This utility model addresses the aforementioned shortcomings of existing technologies by providing a regenerated activated coke drying device. It can utilize activated waste gas to dry the regenerated activated coke, improving the utilization rate of waste heat and saving energy. At the same time, the inner cylinder adopts an open structure at both ends, allowing steam to be directly discharged from both ends of the inner cylinder. The discharge method and structure are simple, saving costs and solving the problems of increased maintenance costs and reduced drying effect caused by steam discharge issues in existing methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A regenerated activated coke drying device includes an inner cylinder and an outer cylinder. The outer cylinder has an air inlet and an air outlet at both ends. The bottom of the outer cylinder is supported by a support frame. The inner cylinder is located inside the outer cylinder. The two ends of the inner cylinder are open and extend out of the outer cylinder. The ends of the outer cylinder and the inner cylinder are sealed by a sealing plate. A motor for driving the inner cylinder to rotate is provided on the side wall of the outer cylinder. A spiral guide plate is provided on the side wall of the inner cylinder.

[0007] Preferably, the air inlet is located at the lower end of the outer cylinder, and the air outlet is located at the upper end of the outer cylinder.

[0008] Preferably, a spiral guide plate that contacts the outer wall of the inner cylinder is connected to the inner wall of the outer cylinder.

[0009] Preferably, the outer cylinder and the inner cylinder are inclined, and the feed end is higher than the discharge end.

[0010] Preferably, a drive ring is fitted on the outer side of the inner cylinder, and a drive groove is provided on the ring surface of the drive ring. Guide wheels that cooperate with the drive groove are provided at both ends of the outer cylinder, and a drive wheel that cooperates with the drive groove is provided on the output shaft of the motor.

[0011] Preferably, the inner cylinder has a feed hopper at the higher end, the feed hopper is connected to the outer cylinder through a fixing frame, and the feed hopper's outlet is located inside the inner cylinder.

[0012] Preferably, the width of the guide plate is no greater than half the radius of the inner cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model can utilize activated waste gas to dry regenerated activated coke, which improves the utilization rate of waste heat and saves energy. At the same time, the inner cylinder adopts an open structure at both ends, and steam can be directly discharged from both ends of the inner cylinder.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] like Figure 1 As shown, a regenerated activated coke drying device includes an inner cylinder 4 and an outer cylinder 2. The outer cylinder 2 has an air inlet 202 and an air outlet 204 at both ends. The air inlet 202 is located at the lower end of the outer cylinder 2 and high-temperature activation waste gas is introduced. The air outlet 204 is located at the upper end of the outer cylinder 2. The waste gas adopts a bottom-in and top-out method, which is more conducive to the flow of high-temperature waste gas.

[0023] The bottom of the outer cylinder 2 is supported by the support frame 5. The inner cylinder 4 is located inside the outer cylinder 2. The two ends of the inner cylinder 4 are open structures and extend out from the outer cylinder 2. The ends of the outer cylinder 2 and the inner cylinder 4 are sealed by a sealing plate to ensure that the exhaust gas can only enter through the air inlet 202 and exit through the air outlet 204. The side wall of the outer cylinder 2 is provided with a motor 3 to drive the inner cylinder 4 to rotate. The side wall of the inner cylinder 4 is provided with a spiral guide plate 403 to facilitate the discharge of activated coke.

[0024] The width of the guide plate 403 is no more than half the radius of the inner cylinder 4. The guide plate 403 can increase the travel of the activated coke in the inner cylinder 4, improve the drying time, and allow the activated coke to be discharged in an orderly manner. In addition, the guide plate 403 will not block the middle space of the inner cylinder 4, ensuring smooth steam flow, enabling the steam to be discharged from the inner cylinder 4 quickly, accelerating the drying speed and improving the drying effect.

[0025] like Figure 3 As shown, in order to ensure the uniformity of heating of the inner cylinder 4, a spiral guide plate 203 is connected to the inner wall of the outer cylinder 2 and contacts the outer wall of the inner cylinder 4. The high-temperature exhaust gas is uniformly heated to the inner cylinder 4 along the guide plate 203, thereby improving the heat utilization rate.

[0026] The outer cylinder 2 and the inner cylinder 4 are set at an angle, and the feed end is higher than the discharge end to improve the smoothness of material discharge.

[0027] like Figure 2 As shown, a drive ring 401 is fitted on the outer side of the inner cylinder 4. A drive groove 402 is provided on the ring surface of the drive ring 401. Guide wheels 201 that cooperate with the drive groove 402 are provided at both ends of the outer cylinder 2. A drive wheel 301 that cooperates with the drive groove 402 is provided on the output shaft of the motor 3. The motor 3 drives the inner cylinder 4 from the outside of the outer cylinder 2, thereby improving the service life of the motor 3 and the convenience of maintenance.

[0028] The inner cylinder 4 has a feed hopper 1 at the higher end. The feed hopper 1 is connected to the outer cylinder 2 through a fixing frame 101. The discharge port 102 of the feed hopper 1 is located inside the inner cylinder 4.

[0029] In use, the regenerated activated coke in the feed hopper 1 enters the inner cylinder 4 through the discharge port. The inner cylinder 4 rotates under the influence of the guide plate 403 and the gravity of the regenerated activated coke, moving from the feed end to the discharge end. At the same time, high-temperature exhaust gas is introduced through the air inlet 202 and discharged through the exhaust port, uniformly heating the inner cylinder 4 along the guide plate 203 to dry the regenerated activated coke. The steam generated during the drying process is directly discharged from both ends of the inner cylinder 4 to dry the regenerated activated coke.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
