[0002] Existing saturated granular activated carbon regeneration technologies mainly include three types: thermal regeneration, solvent regeneration, and biological regeneration. Among them, thermal regeneration technology is the most mature and widely used. Solvent regeneration is effective for specific VOCs, but solvent selection is demanding and it is prone to secondary pollution. Biological regeneration has low energy consumption and is environmentally friendly, but it has strict requirements for conditions and a long regeneration cycle.

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0025] like Figures 1 to 6 As shown, the pre-heat exchange device for a saturated activated carbon thermal regeneration system of the present invention adopts a two-stage series shell-and-tube heat exchange structure. The first-stage heat exchanger 1 is used for heat exchange between the exhaust gas and the heat transfer oil. Because it needs to come into contact with the drying exhaust gas containing volatile organic compounds, corrosive components and high humidity, the shell and heat exchange tubes are made of corrosion-resistant materials. The efficient heat transfer is achieved through the counter-current flow of fluids in the tube side and shell side. The second-stage heat exchanger 2 receives the heat from the heat transfer oil after the first-stage heat exchange and exchanges heat with room temperature air. Considering the non-corrosive properties of air, it is made of ordinary materials. Its heat exchange capacity matches that of the first-stage heat exchanger 1 to ensure that the heat is fully released.
[0026] The shell-side inlet of the first-stage heat exchanger 1 is connected to the exhaust gas outlet of the drying kiln via a dedicated pipeline. The shell-side outlet is connected to the exhaust gas treatment system, and a condensate discharge port at the bottom of the shell side is connected to a wastewater collection device. The tube-side inlet of the first-stage heat exchanger 1 is connected to the outlet of the thermal oil transfer pump, and the tube-side outlet is connected to the tube-side inlet of the second-stage heat exchanger 2, providing a channel for the thermal oil to carry heat into the secondary heat exchange stage. The tube-side outlet of the second-stage heat exchanger 2 is connected to the inlet of the thermal oil storage tank via a pipeline, and the outlet of the storage tank is then connected to the inlet of the thermal oil transfer pump, ensuring that the thermal oil continuously absorbs and releases heat. The shell-side inlet of the second-stage heat exchanger 2 is connected to the outlet of the air fan, and the shell-side outlet is divided into two branches: one is connected to the air replenishment port of the drying kiln to compensate for air loss during the drying process and utilize waste heat to improve drying efficiency; the other is connected to the material preheating inlet of the activated carbon regeneration furnace, realizing multi-scenario heat recovery and utilization.
[0027] By recovering heat from the drying exhaust gas and utilizing it in the electromagnetic drying kiln and regeneration furnace, the energy consumption of the main energy-consuming equipment in the regeneration system is reduced, and the energy utilization efficiency is improved. Compared with the energy use of traditional thermal regeneration technology, the energy consumption of the equipment is greatly reduced. At the same time, the pre-drying treatment of saturated activated carbon can significantly reduce the moisture content of saturated activated carbon, thereby improving the stability of the activated carbon regeneration system.
[0028] By combining heat exchange devices to recover and reuse heat from the drying process, carbon emissions from the system are reduced, meeting environmental protection requirements. At the same time, the reduced energy consumption lowers operating costs for enterprises, resulting in significant economic and environmental benefits.
[0029] Reference Figure 1 , Figure 2 , Figure 3The primary heat exchanger 1 is placed horizontally and is equipped with an inlet pipe 11. The exhaust gas is discharged into the primary heat exchanger 1 through the inlet pipe 11 for heat exchange. An adjustment component 3 and a control component 4 are installed inside the primary heat exchanger 1. The adjustment component 3 and the control component 4 work together to control the pressure and flow rate of the exhaust gas entering the primary heat exchanger 1, thereby ensuring the heat transfer efficiency of the exhaust gas inside the primary heat exchanger 1 and improving the heat exchange efficiency.
[0030] Reference Figure 2 , Figure 3 , Figure 5 The regulating component 3 includes an regulating plate 31, an elastic element 32, and a transmission element 33. The regulating plate 31 is slidably disposed within the primary heat exchanger 1 along its length and is perpendicular to the centerline of the primary heat exchanger 1. The elastic element 32 is a spring and is disposed on the side of the regulating plate 31 away from the control component 4. The elastic element 32 is used to push the regulating plate 31 to move towards the control component 4. The regulating plate 31 is connected to the transmission element 33. The regulating plate 31 and the control component 4 are spaced apart, forming a pressure-stabilizing zone between them. The air inlet pipe 11 communicates with the pressure-stabilizing zone.
[0031] Reference Figure 2 , Figure 3 , Figure 5 The control component 4 includes: a first baffle 41, a second baffle 42, and a control plate 43. The first baffle 41 and the second baffle 42 are spaced apart along the length of the first-stage heat exchanger 1, forming an opening for exhaust gas to pass through between the first baffle 41 and the second baffle 42. The control plate 43 is slidably disposed between the first baffle 41 and the second baffle 42. The transmission component 33 is connected to the control plate 43.
[0032] Initially, the control plate 43 closes the opening, and the pressure stabilizing zone is in a closed state. The exhaust gas enters the pressure stabilizing zone through the intake pipe 11. As the exhaust gas continues to enter, the pressure in the pressure stabilizing zone gradually increases, which in turn drives the regulating plate 31 to move and compress the elastic element 32. After the pressure in the pressure stabilizing zone reaches the specified value, the regulating plate 31 drives the control plate 43 to move through the transmission element 33. The control plate 43 moves to open the opening, allowing the exhaust gas to exchange heat through the primary heat exchanger 1. During the process, the elastic element 32 is always in a compressed state, so that the exhaust gas in the primary heat exchanger 1 always maintains a certain pressure and flow rate, ensuring the heat transfer efficiency of the exhaust gas.
[0033] Reference Figure 2 , Figure 3Both baffle 41 and baffle 42 are perpendicular to the centerline of the primary heat exchanger 1. The primary heat exchanger 1 is cylindrical, and both baffles 41 and 42 are semi-circular. The arc sides of both baffles 41 and 42 are connected to the inner wall of the primary heat exchanger 1. Baffle 41 is located in the upper half of the primary heat exchanger 1, and baffle 42 is located in the lower half. The control plate 43 is perpendicular to baffles 41 and 42. Multiple insertion holes are provided on the adjusting plate 31, baffle 41, and baffle 42. The insertion holes correspond to the heat exchange tubes inside the primary heat exchanger 1, and the heat exchange tubes are inserted into the insertion holes.
[0034] Reference Figure 3 , Figure 5 , Figure 6 The control plate 43 includes: a first intermediate plate 431 and a second intermediate plate 432. A plurality of control holes 433 are evenly provided on the first intermediate plate 431, and a plurality of control holes 434 are evenly provided on the second intermediate plate 432. The plurality of control holes 434 are corresponding to the plurality of control holes 433. The first intermediate plate 431 is fixedly provided between the first baffle 41 and the second baffle 42. The second intermediate plate 432 is slidably engaged with the first intermediate plate 431. The transmission component 33 is connected to the second intermediate plate 432.
[0035] Initially, control hole 2 434 is misaligned with control hole 1 433, and the opening is closed. When the regulating plate 31 moves, it drives the intermediate plate 2 432 to move through the transmission component 33. When the intermediate plate 2 432 moves and control hole 2 434 corresponds to control hole 1 433, the opening is opened, and the exhaust gas can enter the first-stage heat exchanger 1 through the overlapping part of control hole 1 433 and control hole 2 434.
[0036] Reference Figure 1 , Figure 3 , Figure 5 An installation shell 5 is provided outside the primary heat exchanger 1, and a transmission component 33 is disposed inside the installation shell 5. The transmission component 33 includes: a transmission rod 331, a rack 332, a rack 333, and a gear 334. The transmission rod 331 and the rack 332 are slidably assembled inside the installation shell 5, and the sliding direction of the transmission rod 331 and the rack 332 is the same as the sliding direction of the adjusting plate 31. The rack 333 is disposed on the transmission rod 331, and the rack 333 is located on the side of the transmission rod 331 closer to the rack 333. The gear 334 is rotatably assembled inside the installation shell 5, and the gear 334 is located between the rack 333 and the rack 332 and meshes with them. A connecting block 6 connected to the adjusting plate 31 is provided on the transmission rod 331, and a connecting block 61 connected to the intermediate plate 432 is provided on the rack 332.
[0037] Initially, rack 333 and gear 334 are separated, and control hole 433 and control hole 434 are misaligned, with the opening closed. When the adjusting plate 31 moves and compresses the elastic element 32, the rack 333 moves via the transmission rod 331, causing it to move closer to gear 334. After the pressure of the exhaust gas in the pressure stabilization zone reaches the specified value, rack 333 moves to gear 334 and drives gear 334 to rotate. Gear 334 then drives the intermediate plate 432 to move via rack 332, causing control hole 433 to align with control hole 434 and opening the opening.
[0038] Reference Figure 3 , Figure 4 , Figure 5 A transmission rod 2 7 is provided on the adjusting plate 31, and the transmission rod 2 7 is also slidably assembled in the mounting shell 5. The transmission rod 1 331 and the transmission rod 2 7 are symmetrically arranged around the center of the adjusting plate 31, that is, the transmission rod 2 7 is arranged parallel to the transmission rod 1 331. A rack 3 71 is provided on the intermediate plate 2 432, and a rack 4 72 is provided on the transmission rod 2 7. A gear 2 73 is rotatably arranged in the mounting shell 5. The gear 2 73 meshes with the rack 3 71. The rack 4 72 and the rack 3 71 are arranged on the same side of the gear 2 73. The gear 1 334 is arranged between the rack 1 333 and the rack 2 332.
[0039] When rack 4 72 moves to mesh with gear 2 73, it drives intermediate plate 2 432 and adjusting plate 31 to move in the same direction through rack 3 71. When rack 1 333 meshes with gear 1 334, it drives intermediate plate 2 432 and adjusting plate 31 to move in opposite directions through rack 2 332.
[0040] Reference Figure 5 Rack 1 333 and rack 4 72 are spaced apart along the sliding direction of adjusting plate 31, with rack 4 72 located on the side of rack 1 333 away from adjusting plate 31. Rack 3 71 and rack 4 72 are spaced apart along the axial direction of gear 2 73, so that rack 3 71 and rack 4 72 can simultaneously mesh with gear 2 73, with the lower half of gear 2 73 meshing with rack 3 71 and the upper half meshing with rack 4 72.
[0041] When the regulating plate 31 moves, it drives transmission rod 1 331 and transmission rod 2 7 to move synchronously, and simultaneously drives rack 1 333 and rack 4 72 to move closer to gear 1 334 and gear 2 73. When rack 1 333 moves past gear 1 334, it causes control hole 1 433 to completely overlap with control hole 2 434. At this time, the passage is fully open, and gear 1 334 and gear 2 73 are located in the middle position between rack 1 333 and rack 4 72. When the gas pressure in the pressure stabilization zone increases again, the regulating plate 31 continues to move, causing rack 4 72 to mesh with gear 2 73 and causing intermediate plate 2 432 to move in the opposite direction, so as to gradually reduce the size of the overlap area between control hole 1 433 and control hole 2 434, so as to maintain the exhaust gas density in the first-stage heat exchanger 1 within the specified range.
[0042] Reference Figure 3 A clearance groove (not shown in the figure) is provided on the side of the primary heat exchanger 1. The clearance groove is located at the connection between the mounting shell 5 and the primary heat exchanger 1. The clearance groove consists of two parts, one part corresponding to the adjusting plate 31 and the other part corresponding to the intermediate plate 432. The connecting block 6 is connected to the adjusting plate 31 through the clearance groove. A cover plate 9 is provided on the connecting block 6. The cover plate 9 slides against the outer side of the primary heat exchanger 1 and covers the outside of the clearance groove. When the adjusting plate 31 moves, the cover plate 9 always seals the clearance groove to reduce the phenomenon of exhaust gas entering the mounting shell 5. The connecting block 61 is connected to the intermediate plate 432 through the clearance groove. The side of the rack 332 opposite to the gear 334 slides against the outer side of the primary heat exchanger 1. The rack 332 covers the outside of the clearance groove to seal the clearance groove, so that the clearance groove corresponding to the connecting block 61 is always sealed when the intermediate plate 432 moves.
[0043] Reference Figure 3 , Figure 4 A mounting plate 8 is provided on the side of rack 4 72 away from the adjusting plate 31. Rack 4 72 is connected to transmission rod 2 7 through mounting plate 8. A sensing component (not shown in the figure) is provided in the mounting housing 5. A control valve is provided in the air intake pipe 11. The control valve is used to control the air intake volume of the air intake pipe 11. The sensing component includes: a sensing element and a controller. The sensing element is set as a pressure sensor. The sensing element is set on the mounting plate 8 and electrically connected to the controller. The control terminal of the controller is electrically connected to the switch of the control valve.
[0044] As the pressure of the exhaust gas in the pressure stabilization zone increases to a specified value, rack four 72 will mesh with gear two 73 to drive the intermediate plate to move in the opposite direction, thereby reducing the overlap area between control hole one 433 and control hole two 434. If the pressure in the pressure stabilization zone continues to increase, the adjusting plate 31 will continue to move until the mounting plate 8 abuts against gear two 73. At this time, the adjusting plate 31 stops moving. There is still an overlap area between control hole one 433 and control hole two 434, that is, the passage is not completely closed. When the sensor detects that the mounting plate 8 abuts against gear two 73, the controller controls the control valve in the intake pipe 11 to start, reducing the intake volume of the intake pipe 11, thereby reducing the amount of exhaust gas entering, so that the air pressure in the pressure stabilization zone is maintained within the specified range.
[0045] The implementation principle of this invention is as follows: by setting an adjusting plate 31 and a control plate 43, as the pressure in the pressure stabilization zone changes, and as rack one 333 and rack four 72 move to different positions to mesh with gear one 334 or gear two 73, the overlapping area of control hole one 433 and control hole two 434 is controlled, thereby controlling the size of the opening, so as to maintain the pressure of the exhaust gas in the pressure stabilization zone within a specified range, so that the flow density of the exhaust gas in the first-stage heat exchanger 1 is maintained within a specified range, thereby improving the stability and efficiency of heat exchange and reducing energy waste.
[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
