Its catalytic module is mainly honeycomb TiO2-V2O5-WO3 / MoO3¬. After the catalytic module is reversibly deactivated, such as blocked deactivation, it can be restored to 90%-100% of its original activity through processes such as water washing regeneration process, pickling regeneration process, alkali washing regeneration process, and heat regeneration process. Among them, the catalytic module after water washing regeneration needs to be dried. Since the catalytic module is a cuboid, when it is dried by a traditional drying furnace, its heating is uneven, resulting in low drying efficiency, prolonging the drying working time, and increasing the drying energy consumption.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0014] Please refer to Figure 1 , the present utility model provides a technical solution: a catalyst module drying furnace structure, including a plurality of furnace bodies 1 arranged in a straight line, and mounting frames 2 are provided at the tops of the openings at both ends of the furnace bodies 1. A lifting door 3 controlled by a winch is arranged on the mounting frame 2 for sealing the furnace body 1. A partition board 5 is provided on the inner side of the furnace body 1. A wind channel is formed between the partition board 5 and the inner wall of the furnace body 1. A circulation fan 4 is provided at the top of the furnace body 1. The air inlet hopper of the circulation fan 4 is located at the upper end of the inner cavity of the partition board 5, and the air outlet of the circulation fan 4 corresponds to the middle part of the upper end of the wind channel. The lower end of the furnace body 1 is open, and a trolley 6 is slidably arranged at the lower end of the furnace body 1. A material rack 61 for placing materials is provided on the trolley 6. The trolley 6 moves on the track. During dehydration and drying, the circulation fan 4 works, and the hot air flows to both sides under the action of the upper circulation fan 4, and finally passes through the bottom and upward through the center of the catalyst module to complete one cycle.
[0015] When the catalyst module enters and exits the drying furnace, the trolley 6 is used to transfer the catalyst module to a position directly opposite the furnace door. At this time, the lifting door 3 automatically opens, and the external hydraulic push rod starts to push the catalyst module trolley 6. At this time, the trolleys 6 inside the furnace interact with each other, and the first trolley 6 is pushed out of the furnace to complete one feeding, and then the lifting door 3 closes.
[0016] Furthermore, several furnace bodies 1 arranged in a straight line form a drying furnace. The drying furnace is successively divided into a dehydration zone, a high-temperature zone, and a cooling zone along the feeding direction. The main purpose of the dehydration zone is to evaporate the water contained inside the catalyst unit strips.
[0017] Furthermore, an electric heater 7 is provided on the inner side surface of the furnace body 1. The electric heater 7 is located in the air duct and is used for dehumidifying and drying the catalyst module.
[0018] Furthermore, a fresh air pipe 8 communicating with the air inlet hopper of the circulation fan 4 is provided at the upper end of the outer side surface of the furnace body 1. The air inlet of the fresh air pipe 8 is connected to an external fresh air system to facilitate the replenishment of fresh air.
[0019] Furthermore, a moisture exhaust pipe 9 communicating with the air inlet hopper of the circulation fan 4 is provided at the upper end of the outer side surface of the furnace body 1. The moisture exhaust pipe 9 is connected to an external moisture exhaust system. The moisture exhaust system on the furnace body 1 in the dehydration zone is arranged separately to quickly discharge the water vapor generated in the dehydration zone; the moisture exhaust systems on the high-temperature zone and the cooling zone are arranged in parallel to connect the high-temperature air generated in each zone to the dehydration zone, reducing the energy consumption in the dehydration zone.
[0020] The circulation fan 4, the electric heater 7, etc. used in the present utility model are all common electronic components in the prior art. Their working modes and circuit structures are all well-known technologies and will not be elaborated here. The circulation fan 4 and the electric heater 7 are both electrically connected to an external switch group.
[0021] When in use:
[0022] Place the catalyst module on the material rack 61 of the trolley 6, and push the trolley 6 to move on the track through an external hydraulic push rod, so that the trolley moves into the drying furnace;
[0023] The hydraulic push rod pushes the trolley 6, so that the first trolley 6 at the front end is pushed by multiple trolleys 6 at the rear part to complete the simultaneous movement of multiple trolleys 6;
[0024] When the outer trolley 6 enters and moves to an appropriate position inside the drying furnace, the hydraulic push rod shortens and resets, and then the lifting door 3 is closed. At this time, the catalyst in the dehydration zone starts to be heated and dehydrated in the dehydration zone; the catalyst in the high-temperature zone is heated and dried, and the catalyst at the temperature is cooled;
[0025] Moreover, the outer trolley 6 enters and moves to an appropriate position inside the drying furnace. The trolley 6 that was originally in the cooling zone is removed from the drying furnace under the action of thrust, and the catalyst on this trolley 6 has completed the drying operation.
[0026] During dehydration and drying, the circulating fan 4 operates. The hot air flows to both sides under the action of the upper circulating fan 4, and finally passes through the bottom and upward through the center of the catalyst module to complete one cycle.
[0027] The present utility model adopts a method of continuously drying the catalyst module, which can make the catalyst module evenly heated, thereby improving the drying effect and efficiency, shortening the drying time, reducing energy consumption, with simple operation and convenient use.

Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
