Description

Technical Field

[0001] The utility model relates to the technical field of smoke free radical capture, in particular to a cigarette smoke free radical capture device. Background Art

[0002] The hazards of free radicals in cigarette smoke have attracted more and more attention. Free radicals are atoms, molecules or atomic groups containing unpaired electrons that are easy to react with other substances to form stable substances. After the free radicals generated by cigarette combustion pass through the Cambridge filter, part of them are enriched in the tar phase as smoke particle phase free radicals, mainly quinone / semiquinone (Q / QH) free radicals and a small number of polycyclic aromatic hydrocarbon free radicals, graphite carbon and phosphorus free radicals. Free radicals with larger molecular weight and higher stability can be directly observed by electron spin resonance spectrometer (ESR). Particle phase free radicals can directly bind to the DNA of cells to cause cell transformation, and can also undergo self-oxidation reactions to generate a series of active oxygen free radicals to damage cell membranes, thereby leading to a series of smoking-related diseases. In addition, cigarette smoke contains a large number of gas phase free radicals. Gas phase free radicals are highly reactive and can directly attack α1-antiprotease and inactivate it. Gas phase free radicals mainly act on the distal parts of the lungs and are related to the occurrence of peripheral lung cancer. Unlike particle-phase free radicals, gas-phase free radicals are small in size, light in weight, and have poor stability, and cannot be directly observed by ESR. Spin trapping technology is required to capture these active free radicals and convert them into relatively stable spin compounds that can be detected by ESR. The measurement of ESR samples is highly dependent on sample collection, sample preparation, solvent type, temperature, and the selection of spin trapping reagents. Therefore, the capture of free radicals in flue gas is a key step in achieving accurate determination of free radical content, and a reasonable flue gas free radical capture device needs to be designed to achieve maximum capture of free radicals. Although there is currently a method for capturing mainstream smoke, which is to draw the smoke into a capturing liquid through a smoking machine, after the smoke enters the capturing liquid, the capturing liquid will produce a lot of bubbles, and the liquid carried by the bubbles is easily discharged from the container containing the capturing liquid, or even enters the smoking machine, damaging the suction engine of the smoking machine; the capturing liquid can be prevented from entering the smoking machine by increasing the clearance height above the capturing liquid surface, but if the clearance height above the capturing liquid surface is too high, it will greatly increase the possibility of unstable free radicals in the capturing liquid being oxidized, affecting the results of gas-phase free radical detection, and it is impossible to objectively and comprehensively evaluate the content of free radicals in cigarette smoke.

They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the embodiments of the present invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Combine the following Figures 1 to 3 The utility model describes a cigarette smoke free radical capture device.

[0033] like Figure 1As shown, a cigarette smoke free radical capture device comprises: a container 1, an air inlet pipe 2, an air outlet pipe 3 and an air extraction power member (not shown in the figure); the container 1 is used to contain a capture liquid, and the container 1 has an air outlet hole, the air outlet hole is located above the liquid level of the capture liquid, and the air outlet hole is adjacent to the top of the container 1; the first end of the air inlet pipe 2 penetrates the container 1 and extends below the liquid level of the capture liquid; the first end of the air outlet pipe 3 is connected to the air outlet hole, the second end of the air outlet pipe 3 is connected to the air extraction power member, the air outlet pipe 3 has a curved section 32, and the height of any part of the curved section 32 is higher than the height of the air outlet hole; the air extraction power member is used to extract the gas in the container 1.

[0034] Specifically, the container 1 can be a transparent glass tube. The existing smoking machine has a chamber for containing smoke, and the chamber is connected to the second end of the air inlet pipe 2; the suction power part can be specifically the suction engine of the smoking machine, and the suction power part is used to draw air so that the inside of the container 1 is negatively pressurized, so that the smoke enters the container 1 through the air inlet pipe 2 and contacts with the capture liquid, and the capture liquid captures the free radicals in the smoke, and the smoke after the free radicals are captured is discharged from the container 1 through the air outlet pipe 3. The air inlet pipe 2 is provided with a Cambridge filter 4, which can filter out some of the particulate matter in the smoke, so as to facilitate the subsequent (gas phase) free radical capture process.

[0035] The air outlet is located at or adjacent to the top of the container 1, so that the liquid level of the captured liquid in the container 1 is higher, the oxygen content in the container 1 is lower, and the probability of free radicals being oxidized is reduced; the first end of the air inlet pipe 2 is located at the bottom of the container 1, so that the flue gas can fully contact with the captured liquid.

[0036] A large number of bubbles will be generated after the smoke enters the collecting liquid, and the collecting liquid carried by the bubbles can easily enter the exhaust pipe 3. By setting the exhaust pipe 3 with a curved section 32, the movement path of the collecting liquid carried by the smoke in the curved section 32 is made more tortuous. The collecting liquid can be retained in the curved section 32 after contacting the inside of the curved section 32. Moreover, due to the curved structure of the curved section 32, the length allowed to be reached by the curved section 32 is longer in a limited space, and it is more difficult for the collecting liquid carried by the smoke to pass through the curved section 32.

[0037] The cigarette smoke free radical capture device of the utility model sets the height of any part of the curved section 32 to be higher than the height of the air outlet, so that the capture liquid carried by the smoke is difficult to enter the curved section 32, and even if it enters the curved section 32, it is difficult to pass through the curved section 32, which effectively solves the problem in the prior art that the capture liquid is easy to enter the interior of the smoking machine when the space above the capture liquid is small.

[0038] like Figure 1As shown, in some embodiments, the air outlet pipe 3 includes a first connecting section 31, a bending section 32 and a second connecting section 33 connected in sequence, the first end of the first connecting section 31 is connected to the air outlet, the first end of the second connecting section 33 is connected to the air suction power part, and the height of the first connecting section 31 gradually increases from its first end to its second end.

[0039] Specifically, by setting the first connecting section 31 to gradually increase in height from its first end to its second end, part of the captured liquid entering the first connecting section 31 and the curved section 32 can flow back into the container 1, thereby reducing the loss of the captured liquid.

[0040] like Figure 1 As shown, in some embodiments, the curved segment 32 is spiral, and the central axis of the spiral of the curved segment 32 can be along the horizontal direction, or along the vertical or inclined direction.

[0041] like Figure 1 As shown, in some embodiments, the cigarette smoke free radical capture device further includes a hygroscopic member 5 , which is disposed inside the first end of the second connecting section 33 .

[0042] Specifically, since the first end of the second connecting section 33 is connected to the air extraction power member, the hygroscopic member 5 is disposed inside the first end of the second connecting section 33 as the last line of defense, and the hygroscopic member 5 absorbs liquid to prevent the liquid from entering the air extraction power member. At the same time, as the smoke gradually flows in the air outlet pipe 3, the liquid carried by the smoke will gradually decrease. By arranging the hygroscopic member 5 inside the first end of the second connecting section 33, the service life of the hygroscopic member 5 can be increased. The hygroscopic member 5 can be specifically breathable hygroscopic cotton.

[0043] like Figure 1 As shown, in some embodiments, the first end of the air intake pipe 2 is spherical, and a plurality of through holes communicating with the interior of the air intake pipe 2 are provided on the first end of the air intake pipe 2.

[0044] Specifically, by setting the first end of the air inlet pipe 2 to be spherical, the smoke in the air inlet pipe 2 can be sprayed into the capture liquid in different directions, so that the smoke can be in contact with the capture liquid more fully, which is convenient for capturing free radicals.

[0045] like Figure 1 As shown, in some embodiments, the cigarette smoke free radical capture device further includes a bubble piercing component 6, which is disposed in the container 1 or in the air outlet pipe 3, and is used to pierce bubbles formed by the capture liquid.

[0046] Specifically, the bubbles formed by the capture liquid are punctured by the bubble piercing component 6, thereby preventing the bubbles from gradually increasing and eventually causing the capture liquid carried by the bubbles to enter the air outlet pipe 3.

[0047] like Figure 1 to Figure 2As shown, in some embodiments, the bubble assembly 6 includes a first partition 61, which is disposed in the container 1 and tightly fitted with the inner wall of the container 1, and the first partition 61 is located above the liquid surface of the captured liquid. The first partition 61 is provided with a plurality of first air holes 611, and the inner wall of the first air hole 611 and the surface of the first partition 61 both have sharp structures.

[0048] Specifically, the cross section of the container 1 is circular, the first partition 61 is a circular plate, the first partition 61 is detachably connected to the inner wall of the container 1, and the first partition 61 is tightly fitted to the inner wall of the container 1, so that the gas below the first partition 61 enters the upper part of the first partition 61 through the first air hole 611. The inner wall of the first air hole 611 and the surface of the first partition 61 both have sharp structures, and the sharp structures can be sharp protrusions, saw teeth, etc. For example, the surface of the first partition 61 has sharp protrusions, and the inner wall of the first air hole 611 is sawtooth-shaped, and the bubbles are punctured when they contact the sharp structure. A perforation is provided in the middle of the first partition 61 for the air inlet pipe 2 to pass through, and there is a small gap between the inner wall of the perforation and the air inlet. The middle of the first partition 61 is concave downward, so that the captured liquid falling on the first partition 61 can flow back to the bottom of the container 1.

[0049] like Figure 2 As shown, in some embodiments, the first partition plate 61 includes a first area 612 and a second area 613 , the first area 612 is adjacent to the air outlet, and the plurality of first air holes 611 are all located in the second area 613 .

[0050] Specifically, even if the first air holes 611 are provided, there may still be a small amount of bubbles that are not punctured when passing through the first air holes 611, or a small amount of vaporized captured liquid forms bubbles at the upper end of the first air holes 611 after passing through the first air holes 611. By providing a plurality of first air holes 611 all located in the second area 613, these bubbles are kept as far away from the air outlet as possible. Even if these bubbles gradually move toward the air outlet under the action of the air flow, they will be punctured by the sharp structure on the upper surface of the first partition 61. It should be noted that Figure 2 The dotted line in FIG. 6 is only used to distinguish the first area 612 from the second area 613 , and is not an actual structure.

[0051] like Figures 1 to 3 As shown, in some embodiments, the bubble assembly 6 also includes a second partition 62, which is arranged at the air outlet, and a plurality of second air holes 621 are provided on the second partition 62, the inner wall of the second air hole 621 and the surface of the second partition 62 both have sharp structures, and the aperture of the second air hole 621 is smaller than the aperture of the first air hole 611.

[0052] Specifically, the second partition plate 62 is provided to puncture the air bubbles that are about to enter the air outlet pipe 3, so that the captured liquid can flow back. The sharp structure of the second partition plate 62 can be designed with reference to the sharp structure of the first partition plate 61.

[0053] In some embodiments, a certain amount of sodium diethylcarbamodithioate trihydrate (DETC) is dissolved in ethyl acetate, and then subjected to ultrasonic treatment. After the mixture is completely dissolved, a certain amount of FeSO4·7H2O (ferrous sulfate heptahydrate) is added and mixed, and then ultrasonic dissolution is continued to form (DETC)2-Fe 2+ -EA (sodium diethyldithiocarbamate-ferrous ion-ethyl acetate) solution, capture solution (DETC) 2-Fe 2+ -EA solution has a concentration of DETC = 36mmol / L, FeSO4·7H2O = 18mmol / L, which can be used as a trapping solution for nitric oxide free radicals. Take 5ml of nitric oxide free radical trapping solution and add it to container 1. After free radical trapping, transfer the nitric oxide free radical trapping solution into a centrifuge tube and store it for ESR measurement. 2+ The (nitric oxide-sodium diethyldithiocarbamate-ferrous ion) complex is unstable under light conditions and needs to be stored away from light.

[0054] ESR spectrometer detection conditions: test temperature 20°C, detection band X-band, microwave frequency 9.86 GHz, microwave power 10.78 mW, tuning frequency 100 kHz, scanning time 42 s, scanning field width 100 G, center field 3450 G.

[0055] Take 200 μL of the collected liquid in the centrifuge tube and put it into a quartz tube. Place the ESR in a rectangular resonant cavity for detection.

[0056] A series of TEMPO (2,2,6,6-Tetramethyl-1-piperidinyloxy) solutions were prepared with ethyl acetate as solvent, and the ESR spectrum signal intensity was measured as (I1). Coal powder was used as a detection sensitivity calibration sample, and the ESR spectrum signal intensity was measured as (I2).

[0057] The concentration of the Tempo solution was converted into the spin number (N1) according to the following formula (1).

[0058] N1=C1×6.023×10 23 ×V1(1).

[0059] Wherein: C1: concentration of TEMPO standard solution (mol / L); V1: detection volume of TEMPO standard solution (200 μL).

[0060] A regression curve is drawn with the ratio R1=I1 / I2 against the N1 value. The regression analysis equation (2) is as follows:

[0061] R1=aN1-b(2).

[0062] Where: a: slope of the regression curve; b: intercept of the regression curve.

[0063] The signal intensity of the nitric oxide free radical capture liquid measured in the cigarette sample is I3, and the signal intensity of the coal powder measured is I4. The ratio R2 = I3 / I4 is calculated. Substituting R2 into the relationship equation, the N2 value can be obtained. The nitric oxide free radical spin number (N3) of each cigarette is calculated by the following formula (3):

[0064] N3=V0*N2 / nV1(3).

[0065] Where: V0: total volume of the captured liquid; V1: detection volume (200 μL); n: number of cigarettes smoked.

[0066] In some embodiments, a PBN (N-tert-Butyl-α-phenylnitrone) solution (radical trapping solution) with a concentration of 0.05 mol / mL can be prepared with carbon tetrachloride as a solvent. Add 8 mL of the radical trapping solution to container 1, and connect the cigarette smoke radical trapping device to a 20-channel smoking machine for a smoking experiment. After the puffing is completed, the solution of the free radical and PBN adduct is collected and immediately placed in a plastic centrifuge tube and stored in liquid nitrogen. Start the EPR preheating for 1 hour and calibrate the cavity setting parameters. The EPR spectrum is measured using an EMX-6 electron paramagnetic resonance spectrometer: test temperature 20°C, detection band X band, modulation frequency: 100kHz; microwave power: 10mW; modulation amplitude: 0.10mT; sweep width: 100G; scanning time: 41.90s; central magnetic field: 3512G.

[0067] Prepare a series of TEMPO standard solutions with carbon tetrachloride solution. Measure the TEMPO standard solution and record its double integral signal intensity. Dilute the coal powder with calcium carbonate powder to a certain concentration so that its EPR signal intensity is less than the double integral signal intensity of the highest concentration TEMPO standard solution, and use it as a detection sensitivity calibration sample. Convert each concentration point of the TEMPO standard solution into the spin number (N1) according to the following formula (1).

[0068] N1=c×6.023×10 23 ×V1(1).

[0069] Where c is the concentration of TEMPO standard solution (mol / L); V1 is the detection volume of TEMPO standard solution (200 μL).

[0070] The EPR double integral signal intensities I1 and I2 of the TEMPO standard solution of each concentration and the coal powder were measured, and the ratio R1=I1 / I2 was used to make a regression curve regression analysis of the spin number (N1) corresponding to each concentration of the TEMPO standard solution. The relationship equation (2) is as follows:

[0071] R1=aN1-b(2).

[0072] Where: a: slope of the regression curve; b: intercept of the regression curve.

[0073] The signal intensity of the free radical trapping liquid of the measured cigarette sample is I3, and the signal intensity of the measured coal powder is I4. The ratio R2 = I3 / I4 is calculated. Substituting R2 into the relationship equation, the N2 value can be obtained. The number of nitric oxide free radical spins (N3) per cigarette is calculated by the following formula (3):

[0074] N3=V0*N2 / V1(3).

[0075] Where: V0: total volume of the capture solution; V1: detection volume (200 μL).

[0076] The gas phase free radical content in the smoke of 20 smoked cigarettes is averaged to obtain the gas phase free radical content in the smoke of the cigarette in units of spins / cig.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
