Detailed implementation mode

[0025] The present invention provides an aerosol generating device and an activated carbon modification device. To make the purpose, technical solution and effect of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, as well as a specific orientation structure and operation. Therefore, it cannot be understood as a limitation of the present invention. In addition, "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is more than two.

[0027] Please refer to Figure 1 and Figure 2, in the first aspect of the present invention, an aerosol generating device is provided, which includes a modified liquid mixing chamber 11, an aerosol generating assembly 12, an atomizer 13, a sensor 14 and a control device; the aerosol generating assembly 12 includes a plurality of piston cylinders 121; the liquid outlet end of the modified liquid mixing chamber 11 is respectively connected to the plurality of piston cylinders 121 through a liquid outlet pipeline; a valve 122 is provided at the connection between the liquid outlet pipeline and the piston cylinder 121; the outlet ends of the plurality of piston cylinders 121 are respectively connected to the inlet end of the atomizer 13; the sensor 14 is arranged at the outlet end of the atomizer 13 for detecting the particle size and concentration of the aerosol; the control device is electrically connected to the aerosol generating assembly 12, the sensor 14 and the valve 122 respectively.

[0028] The aerosol generating assembly 12 is used to spray the modified liquid droplets into the atomizer 13 at high speed through high pressure. The atomizer 13 is used to mix the modified liquid ejected at high pressure with air to generate an aerosol.

[0029] The present invention can realize the one-step generation of aerosol by mixing multiple modifiers and solutes. The alternating cyclic movement of the plurality of piston cylinders 121 can continuously generate aerosol. At the same time, the sensor 14 can detect the particle size and concentration of the aerosol in real time, and the control device can adjust the aerosol generating assembly 12 and the valve 122 in time to make the formation of the aerosol controllable, solve the problem that the existing technology cannot prepare water-based / oil-based aerosol, and has a wider application range.

[0030] Specifically, the plurality of piston cylinders 121 of the aerosol generating assembly 12 operate alternately, and the pistons 123 therein move back and forth, so as to ensure the continuous formation of the aerosol. When the piston 123 in the piston cylinder 121 moves to the left, the valve 122 opens, and the modified liquid is sucked into the piston cylinder 121. When the piston 123 of the piston cylinder 121 moves quickly to the right, the valve 122 closes, and the modified liquid enters the atomizer 13 in a high-pressure state, and is atomized to form an aerosol. The aerosol is ejected from the atomizer 13 in a high-pressure state. At this time, the sensor 14 detects the ejected aerosol and feeds back the detection result to the control device. The control device can adjust the amount of the modified liquid entering the piston cylinder 121 each time by controlling the valve 122. When the amount of the modified liquid entering the piston cylinder 121 changes, the particle size and concentration of the formed aerosol will also change.

[0031] The following gives a more specific example to illustrate the aerosol generating device of the present invention. Please refer to Figure 3, in this embodiment, the aerosol generating assembly 12 is composed of two piston cylinders 121, namely a first piston cylinder and a second piston cylinder; the outlet end of the liquid outlet pipe and the valves 122 corresponding to the two piston cylinders 121 are connected through a first tee 16; the valves 122 are arranged on the peripheral wall of the piston cylinder 121. When the piston 123 of the first piston cylinder moves to the left, the valve 122 on the first piston cylinder is opened under the control of the control device, and the modified liquid is sucked into the first piston cylinder. At the same time, the modified liquid has been sucked into the second piston cylinder, and the valve 122 on the second piston cylinder is closed under the control of the control device, and the piston 123 of the second piston cylinder moves to the right, and the modified liquid is sprayed into the atomizer 13 at a high speed under high pressure. When the second piston cylinder completes the action, it moves to the left to prepare to suck the modified liquid, and the first piston cylinder moves to the right to spray the modified liquid into the atomizer 13 to form an aerosol, and so on, running periodically.

[0032] Preferably, the operation of the piston cylinder 121 is also controlled by the control device. After the sensor 14 detects the aerosol particle size and concentration, it generates a signal and transmits it back to the control device. The control device controls and adjusts the opening degree of the valve 122 according to the transmitted signal, so as to control the air intake. The control device also controls the movement speed of the piston 123 of the piston cylinder 121, so as to comprehensively control the size and concentration of the generated aerosol particles.

[0033] Preferably, when the aerosol generating assembly 12 is composed of three or more piston cylinders 121, the formation amount of the aerosol will be more stable.

[0034] The aerosol generating assembly 12 of the present invention can atomize the modified liquid into an aerosol at a speed of 0.1 mL / min, and the obtained aerosol particles have a mass median aerodynamic diameter (MMAD) of less than 3 μm.

[0035] Please refer to Figure 2 , in one embodiment, a funnel-shaped cavity 131 is arranged in the atomizer 13; the wide-mouth end of the funnel-shaped cavity 131 is the inlet; the narrow-mouth end of the funnel-shaped cavity 131 is the outlet; the ratio of the cross-sectional area of the narrow-mouth end to the cross-sectional area of the wide-mouth end of the funnel-shaped cavity 131 is 0.02-0.05. The atomizer of this embodiment is still a fluid mixing device designed based on the Venturi effect, which completely relies on the kinetic energy of the fluid itself and can efficiently mix without mechanical stirring, and can handle fluids in different phases. While realizing atomization, it enables effective mixing of gas and liquid to form a uniform aerosol.

[0036] Please refer to Figure 1, in one embodiment, a stirring device 111, a pH meter 112 and a filter 113 are arranged in the modified liquid mixing bin 11; the filter 113 is arranged at the outlet of the modified liquid mixing bin 11. The stirring device 111 is used to fully stir the components in the modified liquid evenly. The pH meter 112 is used to detect the pH value of the modified liquid. The modified liquid mixing bin 11 is used for preparing the modified liquid. For the preparation of the modified liquid partially used for modifying activated carbon, the precise addition of the modifier can be achieved by depending on the pH value of the solution in the modified liquid mixing bin 11. For example, a certain amount of deionized water is first added into the modified liquid mixing bin 11, and then a high-concentration alkali solution is added for dilution, so that the modified liquid can be obtained. If the pH value of the solution is detected in real time, when the pH value reaches the set size, the control device controls the valve body or liquid pump for adding the high-concentration alkali solution to close. The filter 113 is used to filter impurities in the modified liquid to prevent them from entering the subsequent aerosol generating assembly 12 and pipeline.

[0037] Please refer to Figure 1 , in one embodiment, the modified liquid mixing bin 11 is further provided with a solute adding port 114 and a solvent adding port 115. In this embodiment, the modified liquid mixing bin 11 can also be used to prepare the modified liquid by mixing the solute and the solvent.

[0038] Please refer to Figure 1 , in one embodiment, a modified liquid discharge pipeline 116 is arranged on the modified liquid mixing bin 11; the modified liquid discharge pipeline 116 is respectively connected with a modified liquid recovery pipeline 117 and the aerosol generating assembly 12. Specifically, a circulation port and a discharge port are arranged on the modified liquid discharge pipeline 116, the circulation port is connected with the modified liquid recovery pipeline 117, and the discharge port is connected with the aerosol generating assembly 12. The other end of the modified liquid recovery pipeline 117 is connected with a modified liquid recovery bin 15.

[0039] Please refer to Figure 3 , in one embodiment, the piston cylinder 121 includes a piston 123 and a cylinder block 124; a piston rod 125 is connected to the piston 123; the piston rod 125 is in transmission connection with a driving mechanism; the piston 123 is arranged in the cylinder block 124 and is movably connected with the cylinder block 124; the valve 122 is used to control the communication between the cylinder block 124 and the modified liquid mixing bin 11.

[0040] Please refer to Figure 4, the second aspect of the present invention provides an activated carbon modification device, including the aerosol generation device as described above, a modification tank 2, a gas mixing chamber 3, and an air inlet pipe 4. A blower 5 is provided on the air inlet pipe 4; a gas inlet is provided at the bottom of the modification tank 2; the modification tank 2 is used to place granular activated carbon S1; the gas mixing chamber 3 is arranged below the modification tank 2; a gas outlet is provided at the top of the gas mixing chamber 3, an air inlet is provided at the bottom, and an aerosol inlet is provided on the side; the gas outlet of the gas mixing chamber 3 is connected to the gas inlet of the modification tank 2; the air inlet is connected to the air inlet pipe 4; the aerosol inlet is connected to the aerosol generation device.

[0041] The activated carbon modification device converts the modification liquid into aerosol through the aerosol generation device, and uses the fluidization technology to fully mix the aerosol with the activated carbon in the modification tank 2. After reducing the particle size of the modification liquid, the modification liquid can penetrate into the pores of the activated carbon and achieve uniform modification, thereby producing modified activated carbon with stable quality. In addition, the use of this device can also reduce the dosage of the modification liquid, reduce sewage generation, and improve resource utilization rate.

[0042] Specifically, a Venturi tube is provided in the gas mixing chamber 3. The activated carbon modification device of the present invention is suitable for modifying small granular activated carbon with a particle size of 1.5 mm to 10 mm. The air formed by the blower 5 first passes through the gas mixing chamber 3, is mixed with the aerosol through the Venturi effect, and then enters the modification tank 2 to contact the activated carbon particles in the modification tank 2. Due to the small mass of the activated carbon particles, the activated carbon particles will roll under the action of the wind, thus forming a fluidized state. In the fluidized state, the surface of the activated carbon particles can uniformly contact the aerosol. The particle size of the aerosol particles ≤ 3 microns, which can penetrate into the pores of the activated carbon particles for modification, with sufficient modification and avoiding the problem of pore blockage caused by the traditional impregnation method.

[0043] In a preferred embodiment, during fluidized modification, the particle size of the activated carbon particles is 1 to 4 mm, and the air velocity of the blower 5 is 2.5 to 5 m / s.

[0044] Please refer to Figure 5, in one embodiment, a first gas pipeline 21 is provided at the top of the modification tank 2, and the top of the first gas pipeline 21 is communicated with a second gas pipeline 23 or a circulation pipeline 24 through a second three-way pipe 22; a first valve body 81 is provided on the second gas pipeline 23; a second valve body 82 is provided at the air inlet end of the circulation pipeline 24; and the air outlet end of the circulation pipeline 24 is communicated with the air inlet end of the blower 5. In this embodiment, during modification, the first valve body 81 is closed and the second valve body 82 is opened. After the aerosol gas is discharged from the first gas pipeline 21, it enters the circulation pipeline 24, then re-enters the air inlet pipeline 4 through the blower 5, and finally circulates into the modification tank 2, enabling the aerosol to fully contact the activated carbon. After the modification is completed, the second valve body 82 is closed, the first valve body 81 is opened, the aerosol generator is turned off, and the blower 5 remains in operation, and the gas is discharged from the second gas pipeline 23.

[0045] Please refer to Figure 5 , in one embodiment, an air inlet of the blower 5 is connected to a third gas pipeline 25, and the third gas pipeline 25 is communicated with a fourth gas pipeline 27 or a circulation pipeline 24 through a third three-way pipe 26; a third valve body 83 is provided at the air outlet end of the circulation pipeline 24; and a fourth valve body 84 is provided on the fourth gas pipeline 27. When the aerosol gas circulates, both the third valve body 83 and the fourth valve body 84 are opened, and the opening degree of the fourth valve body 84 can be reduced to allow a small amount of external air to be inhaled into the fourth gas pipeline 27 to supplement the circulating gas.

[0046] In a preferred embodiment, a one-way valve is provided at the connection between the aerosol generator and the aerosol inlet. The one-way valve is used to allow the aerosol to enter the gas mixing chamber 3 unidirectionally, preventing the gas from flowing back into the aerosol generator during exhaust or drying.

[0047] Please refer to Figure 5 , in a preferred embodiment, a drying device 7 is provided on the fourth gas pipeline 27. In this embodiment, the drying device 7 is used to form hot drying air after the activated carbon modification to dry the modified activated carbon. During the drying process, the aerosol generating device does not operate. After the hot drying air enters the modification tank 2, it can carry away the moisture in the modified activated carbon. The water consumption of the activated carbon modification equipment of the present invention is less. Therefore, the modified activated carbon can be quickly dried in a short time, with lower energy consumption and less loss of effective components in the modified activated carbon.

[0048] In a preferred embodiment, the activated carbon modification device further includes a vacuum pumping device 6, and the vacuum pumping device 6 is connected to the modification tank 2. In this embodiment, after the activated carbon is loaded into the modification tank 2, the modification tank 2 of the activated carbon is first subjected to vacuum treatment, and then the blower 5 and the aerosol generating device are started. By removing the air in the activated carbon first, the deep pores of the activated carbon can better adsorb the aerosol.

[0049] In summary, through the high-pressure action of multiple piston cylinders 121, the aerosol generating device of the present invention continuously sprays the modification liquid at a high speed towards the atomizer 13, and atomizes the modification liquid in the atomizer 13 to continuously form an aerosol, which can be applicable to form different types of aerosols. In addition, a sensor 14 is provided to detect the formed aerosol in real time, and the operation of the piston cylinder 121 and the valve 122 is feedback-regulated according to the detection result, so as to achieve the purpose of adjusting the aerosol concentration and particle size.
