DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention will be further described below in conjunction with the embodiments.

[0037] Example: Refer to Figures 1 to 11 , an air purification device for preparing potassium superoxide, comprising:

[0038] Base 1;

[0039] The filter mechanism 2 includes a filter box 21 and a condenser 25 fixedly connected to the upper end surface of the base 1. The filter box 21 is provided with a condensation adsorption component 22, at least two guide components 23 and an absorption component 24 in sequence from top to bottom. The filter box 21 is provided with a shunt pipe 212 on the side of the guide component 23;

[0040] The gas absorption mechanism 3 comprises a box body 31 fixedly connected to the upper end surface of the base 1, a partition plate 311 is fixedly connected to the inner middle of the box body 31, the partition plate 311 divides the box body 31 into two purification zones, and the purification zones are filled with absorbent, a heating component 32 is arranged inside the purification zones, a porous exhaust block 36 and a saturation detector 35 are fixedly connected to the inner bottom of the purification zones, cooling components 33 corresponding to the positions of the purification zones are arranged on both sides of the box body 31, and two confluence components 34 are arranged on the upper end surface of the box body 31;

[0041] The air detector 4 is fixedly connected to the upper end surface of the base 1.

[0042] The condensation adsorption component 22 in the filter mechanism 2 can be used to cool the moisture in the air and solidify it into water droplets. At the same time, the condensation adsorption component 22 can also use static electricity to adsorb dust in the air. The guide component 23 can control the airflow direction of the air entering the filter box 21, and can guide the water droplets to contact the absorption component 24. The absorption component 24 can store the water droplets. The gas absorption mechanism 3 forms two purification areas containing absorbents through the partition plate 311, so that after the absorbent in one purification area is saturated, the absorbent in the other purification area continues to adsorb carbon dioxide in the air. The heating component 32 can thermally regenerate the absorbent in the saturated purification area, and the cooling component 33 can cool the absorbent after thermal regeneration.

[0043] Reference Figures 2 to 6 The shunt pipe 212 is fixedly connected to the side of the filter box 21. The shunt pipe 212 has an input end and multiple output ends. The number of the output ends of the shunt pipe 212 corresponds to the number of the guide components 23. The input end of the shunt pipe 212 is fixedly connected to the input pipe 213, and the upper end surface of the filter box 21 is fixedly connected to the outlet pipe 211.

[0044] The condensation adsorption component 22 includes a condensation plate 221 fixedly connected to the inside of the filter box 21, and the condensation plate 221 is hollow. The side of the condensation plate 221 facing the condenser 25 has an input end and an output end, and the input end and the output end of the condensation plate 221 are connected to the input end and the output end of the condenser 25 through a pipe. The internal linear array of the condensation plate 221 is fixedly connected with a plurality of conical frames 222, and the narrow end of the conical frame 222 faces the outlet pipe 211. The inner walls on both sides of the length direction of the conical frame 222 are linearly arrayed with a plurality of guide grooves. The wide end of the conical frame 222 is fixedly connected with a filter screen 223, and the bottom of the filter screen 223 is fixedly connected with an electrostatic device 224 for providing static electricity to the filter screen 223.

[0045] The condenser 25 in the condensation adsorption component 22 can be used to re-cool the coolant that has been circulated and cooled in the condensation plate 221 and re-discharge it into the condensation plate 221, thereby realizing continuous cooling of the condensation plate 221. After the coolant is cooled, the condensation plate 221 can solidify the moisture in the air entering the conical frame 222 to form water droplets, and the electrostatic device 224 provides static electricity for the filter 223, thereby removing dust in the air before solidification when entering the conical frame 222, and using the solidified water droplets to clean the dust adsorbed in the filter 223.

[0046] Reference Figures 4 to 7 The guide assembly 23 includes a rotating shaft 231 rotating inside the filter box 21, and one end of the rotating shaft 231 facing the shunt pipe 212 is fixedly connected with a connecting pipe 235, and the end of the connecting pipe 235 away from the rotating shaft 231 passes through the filter box 21 and is connected with the output end of one of the shunt pipes 212. A plurality of square plates 232 are fixedly connected in an annular array on the outer circumference of the rotating shaft 231, and the square plate 232 is hollow. An L-shaped plate 233 is fixedly connected to one side of the square plate 232 in the length direction, and a plurality of drainage grooves are provided in a linear array on both sides of the concave corner of the L-shaped plate 233, and a plurality of inclined pipes 234 are fixedly connected in a rectangular array on the other side of the square plate 232 in the length direction.

[0047] The connecting pipe 235 in the guide component 23 can be used to transfer air to the rotating shaft 231, and the rotating shaft 231 will further transfer the air to the square plate 232 and discharge it from the inclined pipe 234 of the square plate 232. When the air is discharged from the inclined pipe 234 on the air side, it will also drive the guide component 23 to rotate as a whole. When the guide component 23 rotates, the L-shaped plate 233 can slow down and guide the water droplets carrying dust, and then guide the water droplets carrying dust to the absorption component 24. It should be noted that: in the condensation adsorption component 22, the moisture in the air is cooled and solidified into water droplets in the conical frame 222. Under the action of gravity, the water droplets flow toward the wide end along the guide groove in the conical frame 222. When water drops from the wide end, since the guide component 23 is located as a whole below the condensation adsorption component 22, and the L-shaped plate 233 has a horizontally extending portion, its position can cover the area where condensed water may drip. Even if the guide component 23 is rotating, the concave corner portion of the L-shaped plate 233 is always in a position to intercept the falling condensed water during the rotation process, thereby ensuring that the condensed water can drip on the L-shaped plate 233; and the guide component 23 is different from the existing effect of drying water by the centrifugal force generated by high-speed rotation. The rotation speed of the guide component 23 is relatively slow, and its main purpose is not to shake off the water, but to use the structural characteristics during the rotation process to guide the condensed water.

[0048] Reference Figures 1 to 3The filter box 21 is provided with an outlet on one side of the absorption component 24. The absorption component 24 includes a suction box 241 slidably connected to the inside of the filter box 21. An absorption cloth 242 is clamped in the suction box 241. The upper end surface of the base 1 located between the filter mechanism 2 and the gas absorption mechanism 3 is fixedly connected to a first two-position three-way valve 26. One input end of the first two-position three-way valve 26 is connected to the other end of the outlet pipe 211.

[0049] The absorbing cloth 242 in the absorbing assembly 24 can be used to collect water droplets carrying dust. At the same time, since the suction box 241 and the filter box 21 are slidably connected, the absorbing cloth 242 can be replaced by using the suction box 241.

[0050] Reference Figure 10 to Figure 11 The heating component 32 includes a rotating rod 321 rotatably connected to the inside of the box body 31, and a plurality of groups of connecting rods 322 are fixedly connected to the outer peripheral surface of the rotating rod 321 in an annular array, and each group of connecting rods 322 has a plurality of connecting rods, and one end of each group of connecting rods 322 away from the rotating rod 321 is commonly fixedly connected to a fixed plate 323, and heaters 324 and spoiler covers 325 are respectively fixedly connected on both sides of the fixed plate 323 in the transmission direction, and a plurality of temperature controllers 362 corresponding to the number and position of the heaters 324 are fixedly connected to the outer peripheral surface of the connecting rod 322 in an annular array.

[0051] The heater 324 in the heating component 32 can be used to heat the absorbent in the saturated purification zone, thereby allowing the absorbent to be thermally regenerated, and the temperature controller 362 can control the temperature for thermal regeneration of different types of absorbents. The spoiler 325 can stir the thermally regenerated absorbent entering the heater 324 when the rotating rod 321 rotates, thereby allowing the absorbent in the saturated purification zone to be evenly heated.

[0052] Reference Figures 9 and 10 The cooling assembly 33 includes a heat conductive block 331 fixedly connected to the side of the box body 31, and the side of the heat conductive block 331 facing the purification area passes through the box body 31 and extends into the purification area. The heat conductive block 331 is located on one side of the purification area and is fixedly connected to a plurality of heat conductive balls 333 in a rectangular array, and a fan 332 is fixedly connected to the side of the heat conductive block 331 away from the box body 31.

[0053] The heat of the absorbent after thermal regeneration is absorbed by the heat-conducting balls 333 in the cooling assembly 33 and transferred to the heat-conducting block 331 , and the heat-conducting block 331 can discharge the transferred heat by the fan 332 , thereby cooling the absorbent after thermal regeneration.

[0054] Reference Figures 8 to 10The two confluence components 34 correspond to the positions of the two purification zones. The confluence component 34 includes a confluence cover 341 fixedly connected to the upper end surface of the box body 31. The upper end surface of the confluence cover 341 is fixedly connected to a stop valve 342. The input end of the stop valve 342 is connected to the upper end surface of the confluence cover 341 through a pipeline. The output end of the stop valve 342 is fixedly connected to a transmission pipe 343. The two porous exhaust blocks 36 are fixedly connected to an air supply pipe 361 on one side facing the filtering mechanism 2. The other ends of the two air supply pipes 361 pass through the box body 31 and are respectively connected to the two output ends of the first two-position three-way valve 26.

[0055] A dual driver 37 for driving the two heating components 32 to rotate is provided on the side of the box body 31. A second two-position three-way valve 38 is fixedly connected to the upper end surface of the base 1 located between the gas absorption mechanism 3 and the air detector. The two input ends of the second two-position three-way valve 38 are connected to one end of the two transmission tubes 343 away from the stop valve 342, and an output end of the second two-position three-way valve 38 is connected to the input end of the air detector 4 through a pipeline. The output end of the air detector 4 is fixedly connected to an output tube 41.

[0056] The conduit cover 341 in the conduit assembly 34 can be used to collect the filtered air, and the air stop valve 342 can prevent the pressure generated when the absorbent in the saturated purification area is thermally regenerated from entering the air detector 4.

[0057] The operating principle of this embodiment is as follows:

[0058] The first step: first connect the input pipe 213 to the previous process of the device (the device in this scheme refers to: an air purification device for preparing potassium superoxide) (such as a fan), and then start the device through the controller (the controller is a prior art, so it is not drawn in the figure) to transport the outside air through the input pipe 213 to the shunt pipe 212, and the multiple output ends of the shunt pipe 212 can evenly distribute the air to the connecting pipes 235 of each corresponding guide component 23. When the air enters the connecting pipe 235, the air enters the rotating shaft 231 located inside the filter box 21. After entering the rotating shaft 231, the air will further enter the square plate 232. Since the square plate 232 is a hollow structure, it provides a channel for the flow of air, and the air entering the square plate 232 will be discharged from the inclined pipe 234.

[0059] Among them, when the air is discharged from the inclined pipe 234, due to the impact force of the air and the imbalance of the discharge direction, a torque will be generated to rotate the guide component 23 as a whole around the rotating shaft 231, thereby realizing the rotation of the guide component 23. This rotation not only helps to control the air flow direction in the filter box 21, but also can form an orderly flow path in the filter box 21, thereby increasing the contact opportunity between the air and subsequent components. The air discharged from the inclined pipe 234 will come into contact with the condensation adsorption component 22 during the upward flow process.

[0060] The condensation plate 221 in the condensation adsorption assembly 22 is connected to the condenser 25 by using a pipeline (the condenser 25 is started synchronously with the start-up of the device), thereby forming a circulating coolant loop, thereby realizing cooling treatment of the coolant flowing out of the condensation plate 221, and then re-transporting the cooled coolant back to the condensation plate 221, so that the condensation plate 221 always maintains a relatively low temperature, thereby realizing cooling treatment of the air entering the conical frame 222, so that the conical frame 222 maintains a relatively low temperature;

[0061] When the moisture in the air touches the inner wall of the conical frame 222 with a lower temperature, the moisture in the air will cool and solidify into water droplets, and these water droplets will slowly flow to the wide end along the guide groove in the conical frame 222 under the action of gravity, and the electrostatic device 224 installed at the bottom of the filter 223 and the condenser 25 are started synchronously to generate an electrostatic field, so that the air passes through the filter 223 and enters the conical frame 222 for cooling before adsorbing the dust in the air. When the air passes through the filter 223, the dust particles in the air are adsorbed to the surface of the filter 223 under the action of the electrostatic field. As time goes by, the dust particles gradually accumulate on the filter 223. When the number of solidified water droplets increases and reaches a certain weight, the water droplets fall from the wide end under the action of gravity. During the falling process, the water droplets will entrain the dust adsorbed on the filter 223 and detach from the condensation adsorption component 22, thereby achieving the preliminary cleaning of the dust in the condensation adsorption component 22 and avoiding the excessive accumulation of dust affecting the filtering effect.

[0062] The guide assembly 23 rotates continuously under the impetus of the air discharge. During the rotation process, when the water droplets carrying dust fall from the condensation adsorption assembly 22, the L-shaped plate 233 intercepts and guides the falling water droplets by using the drainage grooves in the concave corners, so that the water droplets carrying dust flow slowly along the direction of the drainage grooves, so as to reduce the speed of the water droplets carrying dust, so that the water droplets carrying dust gradually flow to the absorption assembly 24 under the guidance of the L-shaped plate 233;

[0063] The absorbing assembly 24 is mainly composed of a suction box 241 slidably connected to the inside of the filter box 21 and an absorbing cloth 242 clamped in the suction box 241. When water droplets carrying dust flow into the suction box 241, the absorbing cloth 242 quickly absorbs the water droplets and fixes them in its fiber structure by virtue of its good water absorption and adsorption properties, and also intercepts the dust carried by the water droplets. As the absorbing process continues, when it is necessary to clean or replace the absorbing cloth 242, since the suction box 241 and the filter box 21 are slidably connected, the operator only needs to gently pull the suction box 241 to pull it out of the filter box 21, and then conveniently take out the saturated absorbing cloth 242, replace it with a new absorbing cloth 242, and then push the suction box 241 back to its original position to continue the work of absorbing water droplets.

[0064] Step 2: The air processed by the filter mechanism 2 enters the first two-position three-way valve 26 through the outlet pipe 211. In the initial state (the initial state means that both purification zones are not in use), the first two-position three-way valve 26 guides the air through the air pipe 361 and the porous exhaust block 36 to one of the purification zones (assuming it is purification zone A) in the box body 31. Purification zone A contains an absorbent specially used for adsorbing carbon dioxide. When the air enters purification zone A, the carbon dioxide molecules in the air come into contact with the surface of the absorbent and are adsorbed by the absorbent under physical or chemical adsorption, thereby achieving preliminary purification of the carbon dioxide in the air.

[0065] When the purification area A absorbs carbon dioxide from the air, the saturation detector 35 installed at the bottom of the purification area A constantly monitors the adsorption of carbon dioxide by the absorbent. When the saturation detector 35 detects that the amount of carbon dioxide adsorbed by the absorbent reaches the saturation state, it will feed back information to the controller. After receiving the signal, the controller starts the dual driver 37 (the dual driver 37 has two independent motors, which correspond to the two purification areas respectively, but only one of the dual drivers 37 can be started at the same time, and the motor started at this time is the motor corresponding to the purification area A), and controls the first two-position three-way valve 26 to switch the air flow direction, so that the air enters another purification area (purification area B) in the box body 31 for carbon dioxide adsorption purification (purification area A and purification area B are used alternately);

[0066] The dual driver 37 starts to drive the heating assembly 32 in the purification zone A to rotate, preparing to regenerate the saturated absorbent in the purification zone A, and the rotating rod 321 starts to rotate under the drive of the dual driver 37. The rotating rod 321 will drive the fixed plate 323 connected by the connecting rod 322 to rotate synchronously. At the same time, the heater 324 in the fixed plate 323 starts to be powered on by the temperature controller 362 under the control of the controller. The heater 324 heats up rapidly after being powered on, and the generated heat is transferred to the surrounding absorbent, so that the temperature of the absorbent is increased, thereby breaking the adsorption equilibrium between carbon dioxide and the absorbent, and promoting the desorption of carbon dioxide from the surface of the absorbent, thereby achieving At the same time, in order to ensure that different types of absorbents can be thermally regenerated at an appropriate temperature, the temperature controller 362 monitors the temperature of the absorbent in real time and compares it with the preset temperature value, thereby controlling the power output of the heater 324, thereby ensuring that the absorbent is always in the optimal thermal regeneration temperature range. During the rotation of the rotating rod 321, the spoiler 325 rotates together with the fixed plate 323 to stir the absorbent around the heater 324. This stirring action makes the heat distribution inside the absorbent more uniform, avoids the occurrence of local overheating or overcooling, improves the thermal regeneration efficiency, and ensures the regeneration quality of the absorbent.

[0067] Among them, during the process of thermal regeneration of the absorbent in the saturated purification zone A by the heating component 32, the carbon dioxide inside the absorbent is desorbed to form gas. These gases gradually accumulate in the purification zone A and generate a certain pressure. A stop valve 342 is provided at the connection between the gas pipe 361 and the box body 31. The stop valve 342 is in a closed state under normal circumstances. It will only open when the pressure in the purification zone A reaches a certain threshold to allow the gas to be discharged. This can effectively prevent the pressure generated in the purification zone A from entering the air detector 4 during the thermal regeneration of the absorbent (the pressure can also be urgently discharged to the air detector 4 when the pressure in the purification zone A exceeds the pressure that the filter box 21 can withstand), thereby ensuring that the air detector 4 can accurately detect the air composition after normal purification to avoid misjudgment.

[0068] Among them, when the thermal regeneration process is completed, the regenerated absorbent needs to be cooled down to restore it to a suitable adsorption temperature so that it can be put into use again. At this time, the cooling component 33 starts to work, and the heat-conducting block 331 in the cooling component 33 is in direct contact with the regenerated absorbent. The heat-conducting block 331 can quickly absorb the heat of the absorbent using the heat-conducting ball 333 and transfer the heat to the heat-conducting block 331. At the same time, the fan 332 fixedly connected to the side of the heat-conducting block 331 away from the box body 31 is started, and the airflow generated by the fan 332 quickly takes away the heat on the heat-conducting block 331 and discharges the heat into the surrounding environment. Through the coordinated work of the heat-conducting ball 333, the heat-conducting block 331 and the fan 332, the absorbent after thermal regeneration is efficiently cooled down, so that it can be restored to the optimal adsorption state as soon as possible, and prepare for the next carbon dioxide adsorption work (when the purification area B is saturated, the thermal regeneration process of the absorbent in the purification area B is consistent with the process in the purification area A).

[0069] Step 3: The air purified by the two purification zones (purification zone A and purification zone B) will be collected and processed by the corresponding confluence assembly 34. The collected air will be discharged into the second two-position three-way valve 38 (the second two-position three-way valve 38 is located in the purification zone in the adsorption state and the input end is open) through the air stop valve 342 fixedly connected to the upper end surface of the confluence cover 341 (the air stop valve 342 is in an open state through the controller) and the transmission pipe 343, thereby guiding the purified air to the air detector 4. The air detector 4 can accurately detect various components in the air, including oxygen, carbon dioxide, etc. , moisture and other trace impurities, etc. The air detector 4 compares and analyzes the detected air composition data with the preset purity standard. If the test result shows that the air meets the purity requirement for preparing potassium superoxide, the air will be discharged through the output pipe 41 fixedly connected to the output end of the air detector 4. At this time, the discharged air can be directly used in the subsequent preparation process of potassium superoxide, providing a pure oxygen source for the high-quality preparation of potassium superoxide. On the contrary, if the test result shows that the air does not meet the purity standard, the air detector 4 will send an alarm signal to the controller to prompt the operator to check the device.
