Description

Technical Field

[0001] This utility model belongs to the field of molecular sieve desiccant activation and regeneration technology, specifically a molecular sieve desiccant activation and regeneration device. Background Technology

[0002] Moisture and impurities adsorbed by molecular sieve desiccants can be removed by heating, vacuuming, or introducing inert gas to restore their adsorption performance and enable recycling. An activation and regeneration device is typically used. During operation, the molecular sieve is first heated to desorb, and then purified to restore its adsorption performance. This allows for the recycling of the desiccant, which is widely used in chemical and pharmaceutical industries, improving energy efficiency and reducing production costs.

[0003] Existing molecular sieve desiccant activation and regeneration devices typically only perform simple treatment on the exhaust gas before recovery, but fail to fully utilize the large amount of waste heat carried by the exhaust gas, resulting in the loss of this heat and poor energy utilization. Summary of the Invention

[0004] The purpose of this invention is to provide a molecular sieve desiccant activation and regeneration device. The partition plate and preheating pipe in the preheating box work together to extend the path of the exhaust gas. By fully exchanging heat, the inert gas is preheated, reducing the heat consumption of the regeneration box, reducing the energy consumption of the heating coil, improving the energy cycle efficiency, and saving energy.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A molecular sieve desiccant activation and regeneration device is provided, comprising a regeneration box, two load-bearing plates fixedly connected to the inner wall of the regeneration box, a movable frame disposed inside the regeneration box, the lower surface of the movable frame fitting against the upper surface of the load-bearing plates, a stainless steel mesh box disposed inside the movable frame, a preheating box fixedly connected to the side wall of the regeneration box, and a first exhaust gas discharge pipe fixedly connected to the side wall of the regeneration box, the end of the first exhaust gas discharge pipe furthest from the regeneration box being fixedly connected to the preheating box. The preheating chamber has a first air inlet pipe fixedly connected to its side wall. One end of the first air inlet pipe is fixedly connected to a preheating pipe, which is located inside the preheating chamber. The end of the preheating pipe away from the first air inlet pipe is fixedly connected to a second air inlet pipe. The end of the second air inlet pipe away from the preheating pipe is fixedly connected to the lower surface of the regeneration chamber. The side wall of the preheating chamber away from the first air inlet pipe is fixedly connected to a second exhaust pipe. The inner wall of the preheating chamber is fixedly connected to multiple partition plates, which are fixedly connected to the preheating pipe by fasteners.

[0006] Optionally, a superconducting energy-saving heating coil is fixedly connected to the inner bottom of the recycling box, and the superconducting energy-saving heating coil is located below the load-bearing plate.

[0007] Optionally, a connecting plate is fixedly connected to the side wall of the recycling box, a motor is fixedly connected to the upper surface of the connecting plate, a rotating shaft is fixedly connected to the output end of the motor, a turntable is fixedly connected to the upper surface of the rotating shaft, and a sliding pin is fixedly connected to the upper surface of the turntable.

[0008] Optionally, a connecting column is fixedly connected to the side wall of the movable frame, and a movable plate is fixedly connected to the side of the connecting column away from the movable frame. A sliding groove is formed on the upper surface of the movable plate, and the sliding pin is located inside the sliding groove.

[0009] Optionally, a door is rotatably mounted on the side wall of the recycling box, and a pull ring is fixedly connected to the side wall of the door.

[0010] Optionally, a sealing groove is provided on the side wall of the regeneration box, and a sealing ring is fixedly connected to the inner surface of the sealing groove.

[0011] Optionally, the lower surface of the recycling box is fixedly connected with four legs.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention comprises a superconducting energy-saving heating coil, a regeneration chamber, a first air inlet pipe, a preheating pipe, a second air inlet pipe, a first exhaust gas outlet pipe, and partition plates. During the activation and regeneration of the molecular sieve desiccant, the superconducting energy-saving heating coil heats up, raising the internal temperature of the regeneration chamber. Inert gas from the first air inlet pipe enters the preheating pipe and then the regeneration chamber through the second air inlet pipe. The inert gas blows across the surface of the molecular sieve desiccant, carrying away surface impurities. The exhaust gas enters the preheating chamber through the first exhaust gas outlet pipe, raising the temperature within the preheating chamber and preheating the inert gas that subsequently enters the preheating pipe. The multiple partition plates extend the flow time of the exhaust gas within the preheating chamber, improving the preheating effect on the preheating pipe and thus increasing energy utilization. This invention extends the path of the exhaust gas by combining the partition plate and the preheating pipe inside the preheating box. It achieves preheating of the inert gas through sufficient heat exchange, reduces the heat consumption of the regeneration box, lowers the energy consumption of the heating coil, improves the energy cycle efficiency, and is more energy-efficient.

[0013] This utility model includes a motor, a rotating shaft, a turntable, a sliding pin, a sliding groove, a moving plate, a connecting column, a moving frame, and a stainless steel mesh box. When the motor is working, it drives the rotating shaft and the turntable to rotate, which in turn drives the sliding pin to rotate around the rotating shaft. When the sliding pin rotates around the rotating shaft, since the sliding pin is located inside the sliding groove, it drives the moving plate to move back and forth left and right, which in turn drives the connecting column and the moving frame to move back and forth left and right, and then drives the stainless steel mesh box to move back and forth left and right. This creates gaps between the molecular sieve desiccant particles, reduces the stacking density, makes it easier for hot air to penetrate the particle layer, and improves the overall uniformity of heating.

[0021] Reference Figure 1-5 The present invention will now be described. A molecular sieve desiccant activation and regeneration device includes a regeneration box 1. Two load-bearing plates 2 are fixedly connected to the inner wall of the regeneration box 1. A movable frame 3 is arranged inside the regeneration box 1, with its lower surface abutting the upper surface of the load-bearing plates 2. A stainless steel mesh box 4 is arranged inside the movable frame 3. A preheating box 5 is fixedly connected to the side wall of the regeneration box 1. A first exhaust gas discharge pipe 6 is fixedly connected to the side wall of the regeneration box 1. The end of the first exhaust gas discharge pipe 6 away from the regeneration box 1 is fixedly connected to the side wall of the preheating box 5. A first air inlet pipe 7 is fixedly connected to the side wall of the preheating box 5. An inert gas output mechanism is connected to the first air inlet pipe 7, which can continuously supply inert gas to the first air inlet pipe 7. A preheating pipe 8 is fixedly connected to one end of the first air inlet pipe 7, located inside the preheating box 5. A second air inlet pipe 9 is fixedly connected to the end of the preheating pipe 8 away from the first air inlet pipe 7. The end of the second air inlet pipe 9 away from the preheating pipe 8 is fixedly connected to the regeneration box 1. On the lower surface of the preheating box 5, a second exhaust pipe 26 is fixedly connected to the side wall away from the first air inlet pipe 7. When the molecular sieve desiccant is activated and regenerated, the quartz superconducting energy-saving heating coil 10 heats up, causing the internal temperature of the regeneration box 1 to rise. The inert gas in the first air inlet pipe 7 enters the preheating pipe 8 and then enters the regeneration box 1 through the second air inlet pipe 9. The inert gas blows the surface of the molecular sieve desiccant, carrying away the impurities attached to the surface. The exhaust gas enters the preheating box 5 through the first exhaust pipe 6, causing the temperature in the preheating box 5 to rise, thereby preheating the inert gas that subsequently enters the preheating pipe 8. At the same time, the multiple partition plates 11 can prolong the flow time of the exhaust gas in the preheating box 5, improving the preheating effect of the exhaust gas on the preheating pipe 8, thereby improving the energy utilization rate. Multiple partition plates 11 are fixedly connected to the inner wall of the preheating box 5, and the partition plates 11 are fixedly connected to the preheating pipe 8 by the stabilizing member 12.

[0022] The molecular sieve desiccant activation and regeneration device provided by this utility model, compared with the prior art, extends the path of the exhaust gas by cooperating with the partition plate 11 and the preheating pipe 8 in the preheating box 5, and achieves preheating of the inert gas through sufficient heat exchange, thereby reducing the heat consumption of the regeneration box 1, reducing the energy consumption of the heating coil, improving the energy cycle efficiency, and saving more energy.

Through the high-efficiency heating characteristics of the superconducting thermal material, it provides continuous and stable heat to the inside of the regeneration box 1, meeting the temperature conditions required for the activation and regeneration of the molecular sieve desiccant. It should be noted that the related components used to control the superconducting thermal energy-saving heating coil 10, such as the temperature control device and the power control module, are all located outside the device and are existing technologies, so they will not be described in detail here.

A groove 20 is provided on the upper surface of the movable plate 19. A sliding pin 17 is located inside the groove 20.

A door 21 is rotatably installed on the side wall of the regeneration box 1. A pull ring 22 is fixedly connected to the side wall of the door 21.
