[0002] Ethylene, propylene, and other low-carbon olefins are important basic chemical raw materials. With the development of my country's national economy, especially the development of modern chemical industry, the demand for low-carbon olefins is increasing, and the contradiction between supply and demand will become more and more prominent. The MTO process and the MTP process of methanol to ethylene and propylene are important chemical technologies. Catalysts are required in the process of producing olefins from methanol. However, the granular catalysts still contain a certain amount of moisture during the production process and need to be dried.

[0018] 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.
[0019] Please see Figure 1-4 This utility model provides a technical solution: a methanol-to-olefins catalyst drying device, including a drying chamber 1, a drying plate 4 inside the drying chamber 1, and side baffles 402 fixedly connected to both sides of the drying plate 4. A support rod 408 is fixedly connected to the outer side of the side baffle 402, and one end of the support rod 408 is fixedly connected to the inner side wall of the drying chamber 1. Multiple sets of guide grooves 404 are opened on the upper surface of the drying plate 4, and heating plates 403 are provided on both sides of the guide grooves 404. The lower surface of the heating plate 403 is fixedly connected to the upper surface of the drying plate 4. A support plate 405 is provided below one end of the drying plate 4, and a screening mechanism is provided inside the support plate 405. A discharge port 101 is opened on one side surface of the drying chamber 1, and a guide plate 103 is fixedly connected to the inner side of the discharge port 101. The guide plate 103 is located below the drying plate 4, and one end of the guide plate 103 is spaced apart from one end of the drying plate 4. A feed inlet 102 is fixedly connected to the rear surface of the drying chamber 1.
[0020] As a technical optimization of this utility model, the screening mechanism includes a through hole 406, and a fan blade 407 is rotatably installed inside the through hole 406. A motor II 401 is fixedly installed on the inner surface of the fan blade 407, and the side surface of the motor II 401 is fixedly connected to the support plate 405 through a limiting rod. The dried catalyst can be blown above the guide plate 103 by the motor II 401 and the fan blade 407, and then discharged into the drying chamber 1 through the guide plate 103 and the discharge port 101. The undried catalyst will fall to the bottom of the drying chamber 1 and continue to be dried.
[0021] As a technical optimization of this utility model, a conveyor belt 5 is provided at the other end of the drying plate 4, and a drive shaft 502 is sleeved on the inner surface of the conveyor belt 5. A conveyor frame 501 is fixedly connected to the outer surface of the conveyor belt 5, and one end of the conveyor frame 501 corresponds to one end of the drying plate 4. This allows the undried catalyst at the bottom of the drying box 1 to be conveyed to the upper surface of the drying plate 4 for further drying, and also facilitates the screening of the undried catalyst.
[0022] As a technical optimization of this utility model, a motor I3 is fixedly installed on the rear surface of the drying box 1, and one end of the motor I3 passes through the drying box 1 and is fixedly connected to a stirring shaft 301. A stirring rod 302 is fixedly connected to the side surface of the stirring shaft 301. The stirring shaft 301 and the stirring rod 302 can stir and disperse the undried and agglomerated catalyst, avoiding the difficulty of drying the agglomerated catalyst, thus further improving the drying efficiency of the catalyst.
[0023] As a technical optimization of this utility model, a dryer 2 is fixedly installed on the front surface of the drying chamber 1, and a heater 202 is fixedly connected to the upper surface of the dryer 2. The dryer 2 is connected to the drying chamber 1, and a blower 203 is fixedly connected to the front surface of the dryer 2. Filter plates 204 are provided on both sides of the dryer 2. A gas guide pipe 201 is fixedly connected to the upper surface of the dryer 2, and one end of the gas guide pipe 201 passes through the drying chamber 1 and is fixedly connected to a blowing box 104. The blowing box 104 is located above the drying plate 4. Through the cooperation of the heater 202 and the blower 203 on the upper surface of the dryer 2 with the blowing box 104 at one end of the gas guide pipe 201 on the upper surface of the dryer 2, the catalyst can be further dried, and the drying efficiency of the catalyst can be further accelerated.
[0024] In use, the catalyst particles are first fed into the drying chamber 1 through the feed inlet 102. Simultaneously, the motor I3 and conveyor belt 5 are started. The motor I3 drives the stirring shaft 301 inside the drying chamber 1 to rotate, and the stirring rods 302 on the side surface of the stirring shaft 301 stir the catalyst particles to prevent clumping of the moisture-containing particles. The conveyor belt 5 transports the catalyst particles from inside the drying chamber 1 to the other end of the drying plate 4 via the conveyor frame 501. The catalyst particles are then sprinkled onto the upper surface of the drying plate 4, and the heating plate 403 on the upper surface of the drying plate 4 heats and dries the catalyst particles. Simultaneously, the dryer 2 is activated. The surface heater 202 and blower 203 cause the blower 203 to blow dry hot air into the interior of the drying chamber 1. At the same time, the blower blows the air onto the catalyst particles on the upper surface of the drying plate 4 through the air guide pipe 201 and the air blowing box 104. The catalyst particles on the upper surface of the drying plate 4 will slide downwards. When the drying plate 4 falls past one side of the support plate 405, the motor II 401 and the fan blade 407 can blow the dried catalyst particles into the interior of the guide plate 103 and discharge them into the interior of the drying chamber 1 through the discharge port 101. The catalyst particles that are not completely dried will fall back into the interior of the drying chamber 1 due to gravity. The above drying process is repeated until the particles are completely dried.
