[0017] A method for preparing a nanometer air purification material, using a nanometer air purification material manufacturing device for preparation, the method is specifically as follows:

[0018] The first step is to prepare the nano-purification liquid. First, a certain amount of nano-redox particles, dispersed viscose liquid and potassium permanganate are fed into the preparation kettle. Then, the fluid is fully stirred by an electric stirrer. The stirred fluid is pumped into the spray tank through the first pump body, and the electric stirrer on the spray tank is turned on to keep the fluid in a flowing state.

[0019] In the second step, the carrier is fed into the carrier hopper. The carrier is made of diatomaceous earth, zeolite molecular sieve, activated alumina, silica gel, activated carbon fiber, ceramic mesoporous particles or shell particles. Then, the carrier is conveyed by a conveyor belt, and the carrier is laid by a limiting material plate. With the transmission of the conveyor belt, the carrier is repeatedly turned over by a combing plate. When the carrier is combed, the second pump body works to feed the composite fluid in the spray tank into the spray nozzle, and the carrier is repeatedly sprayed with atomized liquid through the spray nozzle. The atomized liquid can solidify the nano redox particles and potassium permanganate on the surface of the carrier and the inner side of the pores by dispersing the viscose liquid.

[0020] Vacuum drying: after the carrier is loaded, it is sent to the first rotary valve, and then sent to the vacuum cylinder through the first rotary valve, and heated and vacuum dried by the heating rod and vacuum unit of the vacuum cylinder; after the drying is completed;

[0021] During baking and curing, the second rotary valve rotates a set number of times to send the dried carrier at the bottom of the vacuum barrel into the baking pipe section. When heated by the heating tube inside the baking pipe section, nitrogen is continuously introduced into the baking pipe section through the nitrogen protection pipeline to protect the mixed crystal structure of the nano redox particles. After baking and curing, the nano air purification material is obtained; and it is discharged through the third rotary valve.

[0022] The nanometer air purification material prepared by the present invention utilizes the carrier pores to adsorb pollutants in the air. After the pollutants are enriched in the carrier, the pollutants are continuously treated by potassium permanganate and nanometer redox particles in the nanometer purification liquid. During the treatment process, the generated trace intermediate byproducts can be adsorbed by the carrier and will not diffuse into the air. The effective components in the nanometer purification liquid are continuously subjected to purification reaction through the carrier, until they are completely converted into harmless carbon dioxide, water and inorganic substances. The adsorption pores of the carrier are continuously released to realize the continuous in-situ regeneration of the carrier. The dispersion liquid of the dispersed viscose liquid can fully disperse the effective purification components and the viscose liquid, so that the carrier-loaded nanometer purification liquid can be fully mixed and smoothly sprayed out from the spray nozzle in an atomized manner. The effective purification components can enter the pores and external surface of the carrier, and the effective purification components can be positionally solidified by the viscose liquid. The loading amount of the effective purification components can be greatly increased, and they are not easy to fall off and lose after loading. When the effective purification components are gathered on the surface of the carrier in an irregular gap manner, they can be sintered into a mesh body on the surface of the carrier through a baking solidification method.

[0023] Compared with the prior art, the nano air purification material manufacturing equipment and the preparation method thereof of the present invention can realize automatic preparation of nano purification liquid, load the nano purification liquid onto a carrier, and after drying and sintering and solidification, the effective ingredients of the nano purification liquid are fully arranged on the carrier, thereby ensuring that the nano air purification material has an excellent purification effect; it can realize fully automated manufacturing of nano air purification materials, and before the carrier is loaded, it is pre-purified to remove stains and strippable substances on the surface of the carrier, and the pores are fully cleaned, which can increase the loading amount of the nano purification liquid. In addition, the carrier is in a vacuum and nitrogen protection state from the completion of loading to sintering and solidification. During the production process of the nano air purification material, it will not be polluted by air, resulting in loss of nano purification components, thereby ensuring that the nano air purification material has an excellent purification effect.

The nanometer air purification material manufacturing equipment according to claim 1 is characterized in that: The drying unit comprises a limiting cylinder, a drying box is arranged at the bottom of the limiting cylinder, the inner bottom of the drying box is a slope structure and is provided with a heating plate; a discharge door is arranged on the side of the drying box; a rotating motor is arranged at the center of the drying box, a rotating disk is fixed to the rotating end of the rotating motor, and friction patterns are arranged between the rotating disk and the lower disk seat. When working, the lower disk seat and the rotating disk are movably pressed together. When the rotating motor rotates, it can drive the lower disk seat to rotate synchronously, so that the carrier stored on the top of the lower disk seat is centrifugally sent into the inner side of the drying box, and heated and dried by the heating plate. When the humidity of the carrier is lower than the set value, the heating plate is closed, the discharge door is opened, and the carrier is sent to the carrier hopper.

5. The nanometer air purification material manufacturing equipment according to claim 1 is characterized in that: The carrier processing unit works as follows: The carrier is loaded into the inner side of the filter cartridge, and is confined between the lower disc seat and the gland. Then, the carrier passes through the six processing units in sequence through the action of the electric turntable. The specific process is as follows: the filter cartridge first moves to the top of the barrel connected to the ammonia tank, and the hydraulic cylinder drives the swing arm downward to allow the carrier to enter the ammonia tank for ultrasonic immersion. After the immersion is completed for the set time, the drain valve is activated to discharge the floating objects and sediments to the filter tank. After being filtered through the filter, the ammonia is recovered and sent to the ammonia tank through the liquid extraction pump, waiting for the next cycle application. Then, the hydraulic cylinder drives the swing arm upward It is separated from the tank body and enters the pure water tank connected to the tank body for ultrasonic washing; after the ultrasonic washing is completed for the set time, the drain valve is activated and the waste water enters the waste water tank; then, according to the above process, it enters the tank body connected to the nitric acid tank for nitric acid cleaning in sequence, and then it is washed again through another washing unit. After the washing is completed, it enters the tank body connected to the acetone tank for pre-infiltration. After the pre-infiltration is completed for the set time, the drain valve is activated, and the acetone in the tank body is returned to the acetone tank through the filter tank and the liquid extraction pump; finally, the processed carrier is unloaded to the drying unit.

6. A method for preparing a nanometer air purification material, using the nanometer air purification material manufacturing equipment according to any one of claims 1 to 5 for preparation, characterized in that: The method is specifically as follows: The first step is to prepare the nano-purification liquid. First, a certain amount of nano-redox particles, dispersed viscose liquid and potassium permanganate are fed into the preparation kettle. Then, the fluid is fully stirred by an electric stirrer. The stirred fluid is pumped into the spray tank through the first pump body, and the electric stirrer on the spray tank is turned on to keep the fluid in a flowing state. In the second step, the carrier is fed into the carrier hopper. Then, the carrier is conveyed by the conveyor belt, and the carrier is distributed by the limiting material plate. As the conveyor belt is conveyed, the carrier is repeatedly turned over by the combing plate. When the carrier is combed, the second pump body works to feed the composite fluid in the spray tank into the spray nozzle, and the carrier is repeatedly sprayed with atomized liquid through the spray nozzle; the atomized liquid can solidify the nano redox particles and potassium permanganate on the surface of the carrier and the inner side of the pores by dispersing the viscose liquid; Vacuum drying: after the carrier is loaded, it is sent to the first rotary valve, and then sent to the vacuum cylinder through the first rotary valve, and heated and vacuum dried by the heating rod and vacuum unit of the vacuum cylinder; after the drying is completed; During baking and curing, the second rotary valve rotates a set number of times to send the dried carrier at the bottom of the vacuum barrel into the baking pipe section. When heated by the heating tube inside the baking pipe section, nitrogen is continuously introduced into the baking pipe section through the nitrogen protection pipeline to protect the mixed crystal structure of the nano redox particles. After baking and curing, the nano air purification material is obtained; and it is discharged through the third rotary valve.
