Description

Technical Field

[0001] The utility model relates to the technical field of aerosols, in particular to an aerosol collecting device. Background Art

[0002] Aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. The density of these solid or liquid particles can differ slightly or greatly from that of the gas medium. The size of aerosol particles is usually between 0.01-10μm, but the range is very large due to the source and formation reasons.

[0003] Through experiments in the aromatic environmental health project, we found that natural medicinal aromatic plants can produce enough aerosols containing aromatic volatiles under certain conditions. These aerosols will form compounds such as acetaminophen and flurbiprofen under photoheterogeneous catalysis. These compounds contain medicinal compounds needed in the industry and have always been considered to be produced through artificial synthesis. This discovery is different from conventional cognition, that is, natural products can form artificial medicinal compounds under photoheterogeneous catalysis without metal catalysts.

In the description of this application, unless otherwise specified, "plurality" means two or more.

[0027] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] like Figure 1 As shown, an embodiment of the utility model provides an aerosol collection device, which includes an air inlet cavity 100 for containing aerosol and at least one group of collection systems; each group of collection systems includes a reaction container 200 and a post-processing device.

[0029] The air inlet cavity 100 is used to contain aerosols, and can be moved according to the space to be collected and any collection position in the space, so as to realize the collection of aerosols containing volatile gases of aromatic plants in the space.

[0030] Furthermore, the number of groups of the acquisition system can be set according to the experimental needs, such as Figure 1An example of four groups of collection systems is given, but the number of collection systems is not limited to four groups. It can also be one group, two groups, three groups, four groups or more groups. The reaction containers 200 are all connected to the output end of the air inlet chamber 100 through the air inlet branch pipe. In the multi-group collection system, the reaction containers 200 in each group correspond to a separate air inlet branch pipe, which can realize the reaction of aerosols with a variety of different extraction solvents, that is, multiple groups of experimental explorations are carried out at the same time to speed up the operation efficiency; along the fluid flow direction, the reaction container 200 is sequentially provided with an extraction solvent inlet 210, a reactant collection port 220 and a vaporized solvent outlet 230, and an aerosol inlet 240 is provided at one end of the extraction solvent inlet. The air inlet chamber 100 is connected to the reaction container 200 through the air inlet branch pipe and the aerosol inlet 240. The aerosol and the extraction solvent begin to mix at the input end of the reaction container 200 to make the reaction proceed more smoothly.

[0031] Furthermore, the reaction container 200 is connected to a post-processing device via the vaporized solvent outlet 230. The vaporized solvent is processed by the post-processing device, which can reduce or even avoid the discharge of toxic and harmful substances, thereby improving the environmental friendliness of the operation process.

[0032] In some embodiments of the present invention, the reaction container 200 is U-shaped, the extraction solvent inlet 210 and the vaporization solvent outlet 230 are both opened at the end of the reaction container 200 near the top, and the reactant collecting port 220 is opened at the end of the reaction container 200 near the bottom. Preferably, the reactant collecting port 220 is opened at the bottom of the reaction container 200, so as to better collect most of the aerosol precipitated in the extraction solvent through gravity, thereby improving the collection rate.

[0033] Optionally, the reaction container 200 is light-proofed and made of glass, which can effectively prevent the influence of the external environment on the reaction process.

[0034] In some embodiments of the present invention, the post-processing device includes a reflux condensation chamber 300, which is connected to the vaporized solvent outlet 230, and the reflux condensation chamber 300 is provided with a condensing agent inlet 311. The vaporized extraction solvent enters the reflux condensation chamber 300 for recovery and treatment, thereby reducing pollution to the environment.

[0035] Optionally, the reflux condensation chamber 300 includes an outer cavity 310 and an inner pipe 320 disposed inside the outer cavity 310 ; the vaporized solvent outlet 230 is connected to the inner pipe 320 ; and the condensing agent inlet 311 is opened in the outer cavity 310 .

[0036] It can be understood that the inner pipe 320 is made of a material that is not easy to react and is resistant to acid and alkali corrosion, and needs to meet the conditions of pressure resistance and low temperature resistance at the same time, for example, it can be 316 stainless steel, special glass, etc.; the outer cavity 310 is made of a pressure-resistant and low-temperature resistant material, and the condensing agent is a safer, environmentally friendly or high-value-added low-temperature liquid, such as liquid nitrogen, liquefied natural gas, etc.

[0037] In some embodiments of the present invention, the post-processing device further includes a solvent recovery tank 400 , the inner layer pipe 320 is provided with a liquid outlet 321 , and the reflux condensation chamber 300 is connected to the solvent recovery tank 400 through the liquid outlet 321 .

[0038] It can be understood that by providing the solvent recovery tank 400, the solvent can be recovered and recycled, thereby minimizing the loss of solvent and the pollution to the environment.

[0039] In some embodiments of the present invention, the post-processing device further includes a vaporization collection tank 500 , the outer cavity 310 is provided with a condensing agent vaporization outlet 312 , and the reflux condensing chamber 300 is connected to the vaporization collection tank 500 through the condensing agent vaporization outlet 312 .

[0040] It is understandable that when liquefied natural gas is selected as a condensing agent, collecting the vaporized natural gas can ensure safety, and the collected vaporized natural gas can provide energy for peripheral equipment or links, such as constant temperature and humidity adjustment, and can also be transferred to where it is needed for reuse.

[0041] In some embodiments of the present invention, a first generator 610 is provided on the connecting pipe between the reaction container 200 and the reflux condensation chamber 300, and is preferably a pneumatic turbine generator made of special materials, such as a pneumatic turbine generator made of 316 stainless steel or tempered glass.

[0042] It is understandable that the extraction solvent will continue to vaporize and volatilize during the process of extracting the aerosol, and this vaporized and volatilized airflow needs to be recycled to ensure environmental protection and safety. In order to be more environmentally friendly, a pneumatic turbine generator made of special materials is used, and the electricity generated can first be used for the vacuum pump to form a more energy-saving system; but considering that the gas needs to be recycled, in order to prevent the gas from being polluted and doped with more impurities, the first generator 610 needs to be made of an internal contact surface material that is not easy to cause other reactions and is resistant to acid and alkali corrosion, such as 316 stainless steel or special glass, to ensure the purity of the vaporized solvent while improving environmental protection and safety.

[0043] In some embodiments of the present invention, a second generator 620 is provided on the connecting pipe between the reflux condensation bin 300 and the gasification collection tank 500, and is preferably a Tesla pneumatic turbine generator.

[0044] It is understandable that the condensing agent will continue to vaporize during the condensation process, and the vaporized gas is connected to the Tesla turbine generator, contributing to the energy saving of the system; the Tesla pneumatic turbine generator is selected here instead of the pneumatic turbine generator with a conventional structure because the vaporization process of the condensing agent may be relatively slower than that of the extraction solvent. In order to better utilize energy and improve the conversion rate, the Tesla pneumatic turbine generator with a high conversion rate is more suitable than the conventional pneumatic turbine generator.

[0045] In some embodiments of the utility model, the collection device also includes an exhaust device 700, the inner layer pipe 320 is provided with an exhaust port 322, and the exhaust device 700 is connected to the reflux condensation chamber 300 through the exhaust port 322; and / or, the exhaust device 700 is installed between the inner layer pipe 320 and the reaction container 200.

[0046] It can be understood that the vacuum device 700 can make the gas in the pipeline move smoothly along the fluid direction and finally be discharged, which can effectively improve the reaction process and avoid blockage in the pipeline; the vacuum device 700 can be selected as a vacuum pump, and the model of the vacuum pump can be determined according to actual conditions.

[0047] Preferably, the collection device further includes a power storage box 800, the input end of the air extraction device 700 is electrically connected to the first generator 610 and / or the second generator 620 via a wire 900, and the output end is electrically connected to the power storage box 800. After the power required by the air extraction device 700 is used up, any surplus power generated by the generator can be transmitted to the power storage box 800 for storage to be supplied to other places where it is needed.

[0048] In some embodiments of the utility model, connecting pipes and valves are provided between each component, and the cross-sectional areas of the connecting pipe between the air inlet chamber 100 and the reaction vessel 200, the connecting pipe between the reaction vessel 200 and the first generator 610, the connecting pipe between the first generator 610 and the reflux condensing bin 300, the connecting pipe between the reflux condensing bin 300 and the exhaust device 700, the connecting pipe between the reflux condensing bin 300 and the pressure valve, and the connecting pipe between the pressure valve and the second generator 620 are respectively S1, S2, S3, S4, S5, and S6, and the cross-sectional areas between the various connecting pipes satisfy the following conditions: S4≥S1>S2>S3, S1>S2>S3>S5 and S5<S6.

[0049] Furthermore, a pressure valve is provided on the connecting pipe between the reflux condensing bin 300 and the second generator. By providing the pressure valve, the pressure of the vaporized condensing agent can be controlled to reach a certain level before it can pass through. This can not only improve the efficiency of the Tesla pneumatic turbine generator, but also increase the pressure of the reflux condensing bin 300 to a certain extent in order to achieve better and faster condensation effects.

[0050] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
