Description

Technical Field

[0001] This utility model relates to the field of activated carbon pyrolysis regeneration technology, specifically to a waste activated carbon pyrolysis regeneration device. Background Technology

[0002] Activated carbon is an amorphous carbon whose main component is carbon. It has a carbon skeleton structure and contains trace amounts of oxygen, hydrogen, nitrogen, sulfur, and other elements, forming a variety of functional groups and a rich pore structure, giving it excellent adsorption capabilities. Activated carbon regeneration refers to the removal of adsorbates adsorbed on activated carbon using physical or chemical methods without damaging its original structure, restoring its adsorption performance and enabling reuse. Traditional pyrolysis regeneration equipment often involves placing waste activated carbon together for pyrolysis and adsorption regeneration. However, the size of the activated carbon affects its pyrolysis and adsorption effect; the larger the volume, the slower the pyrolysis and adsorption process, ultimately leading to inconsistent pyrolysis and adsorption processes. To improve this situation, a waste activated carbon pyrolysis regeneration device is proposed.

[0003] For example, the activated carbon pyrolysis regeneration device disclosed in the authorization announcement number CN215429088U includes a furnace body, a furnace cover on the upper part of the furnace body, a thermometer and hygrometer on the furnace body, the probe of the thermometer and hygrometer being located inside the furnace body, a separation plate and a sieve plate being arranged inside the furnace body, the separation plate being arranged above the sieve plate being arranged below, the separation plate including several feeding holes and separation blocks, the upper part of the separation blocks being triangular, the sieve plate having sieve holes smaller than the feeding holes, the upper surface of the sieve plate and the upper part of the furnace body bottom plate both having discharge ports, and the upper part of the furnace body having a hot gas inlet pipe and a steam inlet pipe;

[0004] Although it enables hot gas inlet pipe and steam inlet pipe to enter the furnace body, the steam inlet pipe is evenly equipped with steam outlets, and the hot gas inlet pipe is vertically equipped with several branches, each of which is equipped with a hot gas outlet. The device uses a separation plate to separate the feed at the feed inlet. The separated feed is convenient for screening by the screening plate set below. The screening plate can screen the particles according to their size. The activated carbon can be pyrolyzed and regenerated in this furnace body, which can reduce the subsequent screening work.

[0005] However, the existing regeneration equipment does not solve the problems of not being able to finely screen waste activated carbon particles and quickly replace filter blocks, nor is it conducive to stirring the waste activated carbon particles to make them contact the hot steam more evenly, which affects the quality of pyrolysis regeneration of waste activated carbon particles and the convenience of replacing filter blocks. Utility Model Content

[0006] The purpose of this invention is to provide a waste activated carbon pyrolysis regeneration device to solve the problems mentioned in the background art, such as the inconvenience of fine screening of waste activated carbon particles and quick replacement of filter blocks, the difficulty in stirring the waste activated carbon particles to make them contact hot steam more evenly, and the impact on the quality of waste activated carbon particle pyrolysis regeneration and the convenience of filter block replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waste activated carbon pyrolysis regeneration device, comprising a processing tank and a pressure relief valve. A pressure relief valve is located at the center of the top of the processing tank. A screening box is located on one side of the top of the processing tank, and a filter box is located on one side of the top of the processing tank. A first servo motor is located on one side of the top of the processing tank, and an air inlet is located on one side of the top of the processing tank. A limit ring is located on the inner wall of the processing tank, and four sets of equally spaced air inlets are located on the outer wall of the processing tank. A mesh screen cylinder is movably arranged inside the screening box. Four sets of equally spaced guide strips are located on the inner wall of the mesh screen cylinder. A driven gear ring is located on the outer wall of the mesh screen cylinder. A second servo motor is located on the outer wall of the screening box. A second drive shaft is located at the output end of the second servo motor. A second gear is located on the surface of the second drive shaft, and the second gear meshes with the driven gear ring. A first solenoid valve is located at the bottom of the screening box, and the screening box is connected to the processing tank through the first solenoid valve.

[0008] Preferably, the output end of the first servo motor is provided with a first drive shaft, and a first gear is fitted on the surface of the first drive shaft.

[0009] Preferably, a limiting toothed ring is slidably provided inside the limiting ring, and the limiting toothed ring meshes with the first gear.

[0010] Preferably, the bottom end of the limiting toothed ring is symmetrically provided with stirring rods, and the stirring rods are fixedly connected to the limiting toothed ring.

[0011] Preferably, two sets of limiting grooves are symmetrically arranged on the inner wall of the filter box, and the limiting grooves are fixedly connected to the filter box.

[0012] Preferably, the filter box is provided with two sets of filter blocks inside, and the filter blocks can be pulled out from the filter box.

[0013] Preferably, limit strips are symmetrically arranged on the side walls of the filter blocks, and the limit strips are slidably connected to the limit grooves. A second solenoid valve is provided at the bottom of the treatment tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are: this regeneration equipment not only achieves fine screening of waste activated carbon particles and quick replacement of filter blocks, facilitating the stirring of waste activated carbon particles to make their contact with hot steam more uniform, but also improves the quality of pyrolysis regeneration of waste activated carbon particles and the convenience of replacing filter blocks.

[0015] (1) The waste activated carbon particles to be pyrolyzed and regenerated are poured into the mesh screen cylinder. The second servo motor drives the second gear to rotate through the second drive shaft. The second gear drives the mesh screen cylinder to rotate through the driven gear ring. The mesh screen cylinder drives the waste activated carbon particles to rotate. Particles smaller than the diameter of the holes on the surface of the mesh screen cylinder fall into the interior of the processing tank through the mesh screen cylinder and the first solenoid valve. Particles larger than the diameter of the holes on the surface of the mesh screen cylinder remain inside the mesh screen cylinder. Under the guiding action of the guide bar, the guide bar discharges the large particles of waste activated carbon to the outside of the screening box, thus completing the fine screening of the waste activated carbon particles. After that, the first solenoid valve, the second solenoid valve and the exhaust solenoid valve at the bottom of the filter box are closed. Inert gas is injected into the interior of the processing tank through the gas inlet. After the inert gas is filled, heating steam is injected into the interior of the processing tank through the gas inlet. Heating steam comes into contact with the waste activated carbon particles, heating and pyrolyzing them for regeneration. During this process, waste gas is generated, potentially leading to excessive internal pressure. This pressure is released through a pressure relief valve to prevent an explosion. To ensure more uniform contact between the waste activated carbon particles and the hot steam, a first servo motor drives a first gear via a first drive shaft. This gear, in turn, drives a limiting gear ring, which in turn rotates within the limiting ring. The limiting gear ring then drives a stirring rod, which stirs the waste activated carbon particles, further enhancing the uniform contact between the particles and the hot steam. This improves the quality of the pyrolysis regeneration and enables precise screening of the waste activated carbon particles. It also facilitates stirring the particles to ensure more uniform contact with the hot steam, thus improving the overall quality of the pyrolysis regeneration.

[0016] (2) After the waste activated carbon granules have been pyrolyzed and regenerated, the exhaust solenoid valve at the bottom of the filter box can be opened. The exhaust gas enters the filter box through the exhaust solenoid valve and is discharged into the atmosphere after being filtered by two sets of filter blocks. When the filter blocks need to be replaced, pull out the filter blocks. Under the sliding cooperation of the limit strip and the limit groove, the filter blocks are pulled out from the inside of the filter box. Then, replace the new filter blocks and insert them back into the filter box. The activated carbon granules that have been pyrolyzed and regenerated are discharged through the second solenoid valve, which realizes the quick replacement of filter blocks and improves the convenience of replacing filter blocks.

The limiting gear ring 3 then drives the stirring rod 17 to rotate, stirring the waste activated carbon particles to ensure more uniform contact between the particles and the heated steam, thereby improving the quality of the pyrolysis regeneration. This process achieves refined screening of the waste activated carbon particles, facilitates stirring to ensure more uniform contact with the heated steam, and improves the quality of the pyrolysis regeneration of the waste activated carbon particles.

[0035] After the waste activated carbon granules have been pyrolyzed and regenerated, the exhaust solenoid valve at the bottom of the filter box 6 can be opened. The exhaust gas enters the filter box 6 through the exhaust solenoid valve and is discharged into the atmosphere after being filtered by two sets of filter blocks 21. When the filter block 21 needs to be replaced, pull out the filter block 21. With the sliding cooperation of the limiting strip 20 and the limiting groove 19, the filter block 21 is pulled out from the inside of the filter box 6. Then, replace it with a new filter block 21 and insert it back into the filter box 6. The activated carbon granules that have been pyrolyzed and regenerated are discharged through the second solenoid valve 23, which realizes quick replacement of filter blocks and improves the convenience of replacing filter blocks.

[0036] Work steps

[0037] The waste activated carbon granules to be pyrolyzed and regenerated are poured into the mesh screen cylinder 10. The second servo motor 14 drives the second gear 12 to rotate via the second drive shaft 11. The second gear 12 drives the mesh screen cylinder 10 to rotate via the driven gear ring 13. The mesh screen cylinder 10 drives the waste activated carbon granules to rotate. Particles smaller than the diameter of the pores on the surface of the mesh screen cylinder 10 fall into the interior of the processing tank 1 through the mesh screen cylinder 10 and the first solenoid valve 22. Particles larger than the diameter of the pores on the surface of the mesh screen cylinder 10 remain inside the mesh screen cylinder 10 and are guided...

Afterwards, the first solenoid valve 22, the second solenoid valve 23, and the exhaust solenoid valve at the bottom of the filter box 6 are closed, and inert gas is injected into the interior of the treatment tank 1 through the gas inlet 4. After the inert gas is filled, heating steam is injected into the interior of the treatment tank 1 through the gas inlet 9. The heating steam comes into contact with the waste activated carbon particles and heats and pyrolyzes the waste activated carbon particles for regeneration. During the pyrolysis regeneration of granules, waste gas is generated, which can lead to excessive internal pressure. When the pressure becomes too high, it is released through the pressure relief valve 7 to prevent an explosion due to excessive pressure. To ensure more uniform contact between the waste activated carbon granules and the hot steam, the first servo motor 8 drives the first gear 16 to rotate via the first drive shaft 15. The first gear 16 drives the limiting gear ring 3 to rotate inside the limiting ring 2. The limiting gear ring 3 drives the stirring rod 17 to rotate, which stirs the waste activated carbon granules to ensure contact between the granules and the hot steam. To achieve greater uniformity and improve the quality of pyrolysis regeneration, after the waste activated carbon particles have been pyrolyzed and regenerated, the exhaust solenoid valve at the bottom of the filter box 6 can be opened.
