[0002] Activated carbon is a material with rich pore structure and large specific surface area. It can adsorb various substances, such as gases (such as formaldehyde, benzene and other harmful gases), impurities in liquids, etc. It undertakes important purification and separation tasks in many fields. The adsorption performance of activated carbon directly affects the application effect. Therefore, activated carbon needs to be quickly tested for adsorption performance before use. The rapid detection of activated carbon adsorption performance requires the use of an activated carbon adsorption performance rapid detection instrument.

[0003] In the existing technology, although the existing activated carbon adsorption performance rapid detection instrument can perform rapid detection of the adsorption performance of activated carbon during actual use, the accuracy of its detection results is low. The main reason is that the rapid detection instrument does not have a pretreatment function. When the mixed activated carbon particles are of different sizes and some activated carbon particles are relatively wet, the rapid detection instrument without a pretreatment function will not be able to process them. At this time, the accuracy of the activated carbon adsorption performance test results obtained will be reduced, which will not only cause the staff to be unable to accurately know the adsorption effect of the tested activated carbon, but also reduce the use efficiency of the activated carbon adsorption performance rapid detection instrument.

[0025] In this embodiment, when it is necessary to test the adsorption performance of the activated carbon, the sealing plate 105 is first removed from the rectangular block 101, and then the placement frame 106 is removed from between the two sealing rings 103. Then, activated carbon particles are injected into the placement frame 106 until the placement frame 106 is full.

Then, the valve on the gas cylinder 118 is manually opened to allow the gas (formaldehyde gas) in the gas cylinder 118 to enter the interior of the air pipe 116 connected thereto. When everything is ready, the controller 111 is first used to start the fan body 113, one of the electric valves 115 and the two concentration sensors 119 (formaldehyde). Formaldehyde concentration sensor), and then manually turn on the air purifier 123, set the suction speed, and after completing the setting, install the rectangular plate 124 back to its original position.

The treated gas is then further processed by the air purifier 123, ensuring that the gas discharged into the environment does not contain formaldehyde. After the fan body 113 is activated for a period of time, the controller 111 is used to shut down the fan body 113 and the other electric valve 115.

A rotating shaft 211 is rotatably embedded in the inner wall of the shell 201, and a dial plate 212 is fixedly sleeved on the outer surface of the rotating shaft 211. A sealing cover 213 is installed at the opening of the shell 201, and a motor 214 is installed on the surface of the sealing cover 213. A discharge hole 215 is opened on one side of the inner wall of the shell 201 near the bottom, and a hollow block 21 is installed between one side of the shell 201 and one side of the sealing cover 213. 6.

The end face of the connecting plate 206, the end face of the arc plate 205, the end face of the dial plate 212 and the end face of the semicircular sieve plate 209 are all in contact with the surface of the sealing cover 213.

Then, the controller 111 and the hot air blower 202 are connected to the external power supply. Then, the controller 111 is turned on, and the forward and reverse rotation angles and rotation speeds of the output end of the motor 214 are set. Then, the hot air blower 202 is turned on, and the air heating temperature and wind speed are set. Then, the two sealing plugs 208 are respectively installed back to the initial positions. When everything is ready, the motor 214 is started by using the controller 111.

[0028] The effect and working principle achieved by the entire mechanism are as follows: when the activated carbon needs to be pre-treated, the two sealing plugs 208 are first removed, and then an appropriate amount of activated carbon particles are injected into the space composed of the shell 201, the semicircular sieve plate 209 and the sealing cover 213, and then the controller 111 and the hot air blower 202 are connected to the external power supply, and then the controller 111 is turned on, and the forward and reverse rotation angles and rotation speeds of the output end of the motor 214 are set, and then the hot air blower 202 is turned on, and the air heating temperature and wind speed are set, and then the two sealing plugs 208 are respectively installed back to the initial positions. When everything is ready, the motor 214 is started by the controller 111, and the started motor 214 will rotate between the sealing cover 213 and the shell 201. With the cooperation of the rotating shaft 211, the rotating shaft 211 is driven to rotate stably forward and reverse, and then the forward and reverse rotating rotating shaft 211 will also drive the dial plate 212 connected thereto to rotate forward and reverse, and then the forward and reverse rotating dial plate 212 will directly cause the activated carbon particles to flip inside the above-mentioned space. When the activated carbon particles are continuously flipped, the broken particles or powder mixed in the activated carbon particles will pass through the circular holes on the semicircular sieve plate 209 and fall into the space composed of the arc plate 205, the connecting plate 206, the semicircular sieve plate 209, the shell 201 and the sealing cover 213. Then, the hollow block 216 with the filter mesh 217 is removed from between the shell 201 and the sealing cover 213, and then the particles dropped into the space (composed of the arc plate 205, the connecting plate 206) can be removed by using tools. , semicircular sieve plate 209, shell 201, discharge hole 215 and sealing cover 213) are taken out. When the activated carbon particles are turned over for a period of time in the space where they are located and no crushed activated carbon particles or activated carbon powder fall into the space (the space composed of the arc plate 205, connecting plate 206, semicircular sieve plate 209, shell 201, discharge hole 215 and sealing cover 213), the hollow block 216 with the filter mesh 217 is directly installed back to the initial position, and then the hot air blower 202 is started again. At this time, the air outlet end of the started hot air blower 202 will blow out hot air, and then the hot air blown out by the hot air blower 202 will enter the interior of the air guide shell 203, and then enter the connecting pipe 204. The air then enters the space composed of the shell 201, the sealing cover 213, the connecting plate 206, the curved plate 205 and the semicircular sieve plate 209, and then is transported to the space composed of the curved plate 205, the connecting plate 206, the shell 201, the sealing cover 213, the hollow block 216 and the filter mesh 217 through the cooperation of the rectangular groove 210. When the space is continuously injected with hot air, the moisture on the activated carbon particles in the space composed of the shell 201, the semicircular sieve plate 209 and the sealing cover 213 can be evaporated, and then the gas with water vapor will pass through the mesh of the filter mesh 217 and be discharged into the environment. When the activated carbon particles have been dried for a period of time, the hot air blower 202 is directly turned off.Then, the controller 111 is used to pause the motor 214, and then the hollow block 216 with the filter mesh 217 is removed. The waste (crushed activated carbon particles or activated carbon powder) left inside the hollow block 216 is taken out, and then the motor 214 is first removed from the sealing cover 213, and then the sealing cover 213 is removed from the shell 201. Then, the activated carbon particles (same size and in a dry state) in the space composed of the shell 201, the semicircular sieve plate 209 and the sealing cover 213 are taken out, and the pretreatment of the activated carbon particles is completed. Finally, the sealing cover 213 and the motor 214 are installed back in place in sequence. When it is necessary to test the adsorption performance of the activated carbon, the sealing plate 105 is first removed from the rectangular block. 101, then remove the placement frame 106 from between the two sealing rings 103, and then inject activated carbon particles into the placement frame 106 until the placement frame 106 is full. Then, install the placement frame 106 and the sealing plate 105 back to their original positions in turn, and then remove the cover plate 112 and the rectangular plate 124. Then manually open the valve on the gas cylinder 118 to let the gas (formaldehyde gas) in the gas cylinder 118 enter the air pipe 116 connected to it. When everything is ready, first use the controller 111 to start the fan body 113, one of the electric valves 115 and the two concentration sensors 119 (formaldehyde concentration sensors), and then manually turn on the air purifier 123, set the suction speed, and then After the setting is completed, the rectangular plate 124 is installed back to its original position. At this time, the started fan body 113 will directly extract the formaldehyde gas that reaches the inside of one of the air pipes 116 through the three-way pipe 114 connected to it, the closed other electric valve 115 and the opened one of the electric valves 115, and transport the formaldehyde gas to the inside of the corresponding funnel trough 104 through the cooperation of the other air pipe 116 and one of the circular tubes 107. When the formaldehyde gas reaches the inside of the funnel trough 104, the opened concentration sensor 119 will detect the concentration of the formaldehyde gas entering the funnel trough 104, and transmit the detected concentration data directly to the controller 111. After receiving the data, the controller 111 will directly It is recorded, and then the formaldehyde gas entering the funnel groove 104 will pass through the interior of the corresponding sealing ring 103 and the circular hole on the placement frame 106, and come into contact with the activated carbon particles. When the gas comes into contact with the activated carbon particles on the placement frame 106, the activated carbon particles will adsorb the formaldehyde gas. Then, the gas ejected from the circular hole of the placement frame 106 (the gas treated by the activated carbon particles) will enter the interior of another funnel groove 104. When the treated gas enters the interior of another funnel groove 104, the concentration sensor 119 (corresponding to the other funnel groove 104) that is turned on at this time will detect the concentration of the gas entering the corresponding funnel groove 104, and transmit the detected concentration data to the controller 111.When the controller 111 receives the concentration data transmitted by the concentration sensor 119 (corresponding to another funnel tank 104), the controller 111 will record it, and then close the opened electric valve 115 and the two concentration sensors 119 in turn, and open another electric valve 115. Then, the gas entering the other funnel tank 104 will pass through the inside of the circular tube 107 connected to it and enter the inside of another placement tank 108. After that, the gas entering the inside of the other placement tank 108 will pass through the first baffle 120 and the second baffle 121 to complete the speed reduction (to prevent the gas flow rate from being too fast and affecting the activated carbon adsorption performance test). Then, the gas with reduced speed will be sucked in and purified by the air purifier 123. After that, the purified gas will enter the inside of the auxiliary pipe 122, and finally pass through the inside of the cylindrical hole 125 and be discharged into the environment. At the same time, the fan body 113 will be opened The other electric valve 115, one of the closed electric valves 115, and the previously coordinated components work together to draw in air from the environment. This drawn-in air (from the environment) transports all the remaining gas (formaldehyde gas) inside the three-way pipe 114, the other air pipe 116, one of the circular tubes 107, the fan body 113, the corresponding funnel trough 104, and the corresponding sealing ring 103 to the interior of the placement frame 106 for adsorption by the activated carbon particles. The treated gas is then further treated by the air purifier 123, ensuring that the gas discharged into the environment does not contain formaldehyde. After the fan body 113 has been running for a period of time, the controller 111 is used to shut down the fan body 113 and the other electric valve 115. The rectangular plate 124 is then removed, and the air purifier 123 is turned off. The adsorption efficiency formula can then be used to determine the adsorption performance of the activated carbon.

[0029] Among them, adsorption efficiency: It can reflect the ability of activated carbon to remove adsorbent (formaldehyde gas). The higher the adsorption efficiency value, the better the adsorption effect of activated carbon on the gas, that is, the better the adsorption performance; , η is the adsorption efficiency, C0 is the initial concentration of formaldehyde gas just entering the funnel tank 104 corresponding to one of the circular tubes 107, and C1 is the gas concentration (entering the inside of the funnel tank 104 corresponding to the other circular tube 107 and being the treated formaldehyde gas).

[0030] The hole reserved on the rectangular plate 124 is used for the power cord of the air purifier 123 to pass through, which facilitates the connection of the air purifier 123 to an external power source.

[0031] The two electric valves 115 , the fan body 113 , the two concentration sensors 119 and the motor 214 are all connected to the controller 111 via wires.

[0032] Among them, the controller 111 (PLC controller), the fan body 113, the electric valve 115, the gas cylinder 118, the concentration sensor 119, the air purifier 123, the hot air blower 202 and the motor 214 are all existing technologies, and their models can be selected according to actual conditions, so no further explanation is given here.
