The present invention relates to an anti-pollution efficiency measuring device and a measuring device using carbon black fine dust, and in detail, fine dust formed by generating a quantity of carbon black in a chamber housing adheres or does not adhere to a sample having a constant surface area. It relates to an apparatus for evaluating the function of anti-pollution of fine dust measured using a plurality of measuring instruments mounted inside the chamber.

As is well known, as interest in the environment has increased rapidly in recent years, the majority of the urban population has also increased interest in blocking particulate matter (PM). Fine dust is an agglomerated particulate matter that floats or scatters in the air, and can be classified into _{fine dust (PM 10} ) whose particle diameter is less than 10 μm and ultrafine dust (PM _{2.5) whose diameter is less than 2.5 μm.} Fine dust is composed of dioxin, mercury, cadmium, sulfate, and nitrate lumps. In 2013, it was designated as Group 1 carcinogens (Group 1) that were confirmed to be carcinogenic to humans by the International Cancer Research Institute under the World Health Organization. Long-term exposure to such fine dust causes a rapid decline in the human body's immunity and causes various diseases that are harmful to the human body, such as respiratory diseases such as asthma and bronchitis, and cardiovascular, eye, and skin diseases.

In order to fundamentally block fine dust that causes skin diseases among the above harmful effects, the cosmetic industry is releasing anti-pollution functional cosmetics that can reduce the effect of fine dust on the skin one after another. However, in order to secure the objectivity and reliability of the evaluation method of such anti-pollution functional cosmetics, a device and an analysis method for testing the fine dust protection rate are essential.

Checking the effect. Likewise, Korean Patent Publication No. 10-1737611 discloses that the arm of the test subject with the application area to which the cosmetic material is applied and the sub application area to which the cosmetic material is not applied is inserted into the chamber, and then sprays fine dust, respectively, before and after exposure to the fine dust. The effect of preventing adsorption of fine dust is confirmed by comparing and analyzing the image of the photographed subject.

However, in the above-described prior art, in view of the fact that the test subject's arm should be inserted into the chamber to be tested, fine dust contamination generated during insertion/retraction, measurement errors due to optical exposure, etc., the in vitro test method should be prioritized. It becomes a problem for reproducibility and objectivity.

Therefore, the definition should be made based on the contents throughout the present specification.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a front view of an apparatus for measuring anti-pollution efficiency using carbon black fine dust according to an embodiment of the present invention, and FIG. 2 is an anti-pole using carbon black fine dust according to an exemplary embodiment of the present invention. It is a diagram illustrating the side of the device for measuring lution efficiency.

1 and 2, the apparatus for measuring anti-pollution efficiency using carbon black fine dust according to an embodiment of the present invention includes a body part 110, a supply circulation part 120, a holder part 130, and a measurement. It may include a unit 140, a cleaning unit 150, and the like.

The main body 110 is a main body of an apparatus for measuring anti-pollution efficiency using fine carbon black dust, and may include a chamber housing 111, a chamber door 112, and the like.

The chamber housing 111 is a body of the main body 110, and the front surface thereof is opened so that the chamber door 112 may be coupled. In addition, since the accuracy of fine dust measurement may be impaired due to static electricity generated by the chamber housing 111 itself, the chamber housing 111 may be formed of a non-metallic material.

The chamber door 112 opens and closes the chamber housing 112 and may be coupled to the open front surface of the chamber housing 111.

In addition, in order to prevent fine dust inside the chamber housing 111 from leaking to the outside through the front of the chamber housing 111, the outer peripheral surface of the chamber door 112 is provided with a sealing unit (not shown) such as rubber. As a result, the chamber housing 111 can be sealed.

The supply circulation unit 120 is a member that supplies fine dust to the body unit 110 and circulates the supplied fine dust, and includes a fine dust generator 121, an inlet fan 122, and a control valve 123. ), a circulation fan 124, a discharge valve 125, and the like.

The fine dust generator 121 generates fine dust and supplies it to the main body 110, and may be provided inside the main body 110.

The fine dust generator 121 may generate fine dust containing carbon black of _{PM 10} and PM _{2.5 as a main component.} Carbon black is soot produced when carbon-containing substances such as coal, wood, and oil are incompletely burned, and is equivalent to ultrafine dust less than 2.5 micrometers in diameter.It is mainly contained in the smoke emitted by diesel vehicles and the smoke emitted from thermal power plants. have.

The inlet fan 122 is provided in the chamber housing 111 and is connected to the fine dust generator 121 to introduce fine dust into the main body 110, and external air is supplied to the main body through the inlet fan 122. By introducing into 111), it may serve to transmit fine dust generated inside to the main body 110.

The control valve 123 introduces fine dust into the chamber housing 111 or blocks the inflow of fine dust, and may play a role of controlling the inflow of fine dust.

In order to create a contaminated artificial atmosphere, a quantity of artificially generated fine dust may exist in the artificial atmosphere. By controlling the inflow of fine dust with the control valve 123, the fine dust can be introduced and blocked at a concentration desired by the user.

The circulation fan 124 is provided on the upper part of the chamber housing 111 to circulate fine dust inside the chamber housing 111, and the fine dust introduced through the control valve 123 is evenly distributed inside the chamber housing 111. It can play a role of distributing.

The discharge valve 125 is provided above the chamber housing 111 and serves to discharge fine dust inside the chamber housing 111 to the outside.

After fine dust flows into the chamber housing 111 and measurement is completed by the measuring unit 140, all fine dust remaining in the chamber housing 111 must be discharged to the outside. This is because, when the remaining fine dust is adsorbed on the body part 110 or the like, it may be difficult to accurately measure the fine dust concentration when re-measurement, and the body part 110 and the like itself may be contaminated.

In addition, by connecting a fume hood (not shown) that can be exhausted to the discharge valve 125 and injecting compressed air into the control valve 123, fine dust remaining in the chamber housing 111 can be removed. .

The holder unit 130 is a member provided inside the body unit 110 and is provided with a sample 132b to which fine dust is adsorbed, and includes a holder 131, a sample holder 132, a holder opening/closing lever 133, and the like. Can include.

The cradle 131 is formed downward on the upper surface of the chamber housing 111 and may support the sample holder 132, the holder opening/closing lever 133, and the like.

The sample holder 132 may be disposed according to the position where the fine dust is adsorbed, and the holder 131 may also be formed in the chamber housing 111 according to the position where the sample holder 132 is disposed.

The sample holder 132 is coupled to the holder 131 so as to move up and down, and includes a sample dish 132a to which the sample 132b is attached and detached, and is formed of at least one.

The sample holder 132 is disposed at various positions such as the upper and lower parts of the chamber housing 111 according to the position where fine dust is adsorbed, so that the fine dust circulating inside the chamber housing 111 is not affected by the adsorption position. It can be sufficiently adsorbed to (132b).

In addition, the sample holder 132 is opened and closed by the holder opening/closing lever 133, so that fine dust is adsorbed to the sample 132b.

The sample dish 132a is coupled to the sample holder 132 and may be provided so that the sample 132b is detachably attached. The sample dish 132a may be formed of a material such as STS (stainless steel) of about 3 inches (about 76 mm) and mounted on the sample holder 132.

As the sample 132b, fine dust is adsorbed, and since various types of samples 132b having different adsorption rates of fine dust may be used, the adsorption efficiency of fine dust by the sample 132b can be determined in various ways.

The holder opening/closing lever 133 is formed on the outer upper end of the chamber housing 111 and serves to open and close the sample holder 132.

After the fine dust enters the chamber housing 111, the sample holder 132 is completely sealed using the holder opening/closing lever 133 until the artificial atmosphere is created, thereby preventing the fine dust from adsorbing to the sample 132b. Can be prevented.

In addition, after the artificial atmospheric environment is created, the sample holder 132 is opened using the opening/closing lever 133, so that fine dust may be adsorbed onto the sample 132b.

The measurement unit 140 is a member that measures the concentration of fine dust inside the body unit 110 and may include a concentration meter 141, an image recorder 142, and the like.

At least one concentration meter 141 is provided inside the main body 110 and measures and outputs the concentration of fine dust, and is mounted inside the chamber housing 111 that is sealed by the chamber door 112, thereby It is possible to accurately measure the concentration value of the fine dust inside the main body 110 without being affected by the environment or the like.

When the sample holder 132 on which the sample 132b is mounted is sealed and fine dust flows into the chamber housing 111, the concentration meter 141 creates an artificial atmosphere inside the chamber housing 111 by the fine dust. Until the composition is formed, the concentration of fine dust can be measured in real time, and the measured value can be output to a display (not shown) provided in the concentration meter 141 or the like.

As the fine dust is continuously circulated within the chamber housing 111, a difference may occur in the concentration measurement value of the fine dust depending on the measurement location, so that at least one concentration meter 141 is provided to the inside of the chamber housing 111 It is possible to reduce the deviation of the measurement value of fine dust concentration by placing it at various locations in the

In addition, when the sample holder 132 is opened due to the creation of an artificial atmospheric environment, the concentration measuring instrument 141 measures the concentration value of the fine dust present in the chamber housing 111 in real time as fine dust is adsorbed to the sample 132b. And the measured value may be output to a display (not shown) provided in the concentration meter 141 or the like.

Meanwhile, the operation method of the concentration meter 141 can be measured by a dynamic light scattering (DLS) method in which the frequency of the pulse signal of the scattered light received from the particles is proportional to the density of the particles. It may be provided in a form capable of analyzing the concentration.

The image recorder 142 is formed outside the main body 110 and serves to record a measurement value of the concentration of fine dust output from the concentration meter 141 as an image.

The concentration of fine dust measured by the concentration meter 141 is measured in real time and output to the display, but there is a limit to recording the measured value of the concentration in real time. By recording the dust concentration measurement value as an image, a quantitative analysis of the fine dust concentration can be performed based on the recorded data.

The cleaning unit 150 removes fine dust from the main body 110 and prevents static electricity from being generated in the main body 110, and may include a cleaner 151, a static electricity eliminator 152, and the like.

The cleaner 151 is to remove fine dust inside the main body 110, to accurately measure the fine dust concentration, and to prevent contamination of the main body 110 and the like due to fine dust.

Before the fine dust is supplied to the main body 110 in order to create an artificial atmospheric environment, if fine dust or the like remains in the main body 110, an error may occur in the set fine dust concentration value. It can be difficult to create a working environment. In addition, when the fine dust concentration measurement experiment is completed and the fine dust of the main body 110 is not discharged to the outside of the laboratory, there is a possibility that the inside of the laboratory or the main body 110 may be contaminated.

Accordingly, compressed air is injected into the control valve 123 to circulate the remaining fine dust, and a fume hood (not shown) is connected to the discharge valve 125 to suck and discharge the circulating fine dust. Fine dust such as the part 110 can be removed.

The static electricity eliminator 152 prevents the generation of static electricity in the main body 110 before fine dust is supplied to the main body 110 in order to create an artificial atmospheric environment, and is to accurately measure the fine dust concentration. .

When static electricity is generated by fine dust, an error may occur in the measured value of the concentration of the fine dust, and sparks may be generated due to static electricity and a fire may be caused. Therefore, an antistatic device 152 such as an antistatic spray is used. By using it, the generation of static electricity can be prevented in advance.

Among the configurations included in the body part 110, the supply circulation part 120, the holder part 130, the measuring part 140, the cleaning part 150 as described above, the configuration using power is the main body part 110 Power may be applied from a power device provided outside of the device. This is because when the power supply device is formed inside the main body 110, there is a concern that circulation of fine dust may be inhibited or the accuracy of the measurement value of the fine dust concentration may be reduced due to an electric field generated from the power supply device. to be.

Next, a process of measuring the anti-pollution efficiency with an anti-pollution efficiency measuring apparatus using carbon black fine dust having the above-described configuration will be described.

3 is a step-by-step flowchart showing a process of measuring anti-pollution efficiency using fine carbon black dust according to another embodiment of the present invention.

Referring to FIG. 3, a pre-treatment step of removing fine dust inside the main body 110 and preventing the generation of static electricity is performed (step 201).

In order to measure the concentration of fine dust, if fine dust remains inside the body part 110 before the fine dust is introduced, an error may occur in the set fine dust concentration value, so it is difficult to create a desired working environment by the user. , Compressed air is injected into the control valve 123 to circulate the remaining fine dust, and a fume hood (not shown) is connected to the discharge valve 125 to suck and discharge the circulating fine dust. 110) and other fine dust can be removed.

In addition, before being injected into the body portion 110, static electricity that may be generated in the body portion 110 may be prevented, so that the concentration of fine dust can be accurately measured. This is because the accuracy of the measurement of the fine dust concentration may be reduced due to the adsorption of fine dust and static electricity, and there may be a risk of a fire in a device using power when a spark due to static electricity occurs.

Subsequently, after attaching the sample 132b to the sample holder 132 and closing the sample holder 132 with the holder opening/closing lever 133, fine dust is supplied to the main body 110 to create an artificial atmosphere. (Step 202).

By attaching the sample 132b to which fine dust is adsorbed to the sample holder 132 and closing and sealing the sample holder 132 with the holder opening/closing lever 133, the sample ( Adsorption to 132b) can be suppressed.

In addition, after the sample holder 132 is closed, in order to create an artificial atmospheric environment set by the user, as described above, fine dust and the like, mainly composed of carbon black of _{PM 10} and PM _{2.5, are used in the main body 110.} Can be supplied to

Subsequently, a first measurement step of measuring and recording the concentration of fine dust in the artificial atmospheric environment is performed (step 203).

The concentration value of the fine dust measured in the first measurement step (i.e., the first concentration data) is the concentration value of the fine dust in the artificial atmosphere in which fine dust is not adsorbed by the sample 132b. It is an element that can determine whether or not it has been created. Accordingly, when the fine dust concentration value inside the main body is different from the set fine dust concentration value and an artificial atmosphere is not created, step 201 may be performed again.

That is, if the artificial air environment set by the user is not created even if the fine dust is supplied for a certain period of time, all the supplied fine dust is discharged, the work to prevent static electricity generation is performed again, and then the fine dust is supplied again. Thus, the process of re-creating the artificial atmospheric environment can be performed.

After the creation of the artificial air environment is completed, the sample holder 132 is opened and fine dust is adsorbed on the sample 132b, and a second measurement step of measuring and recording the concentration of the fine dust inside the main body 110 is performed. Is performed (step 204).

When the sample holder 132 is opened, fine dust is adsorbed from the samples 132b arranged at various locations inside the main body 110, and at the same time, fine dust that is not adsorbed and exists in the artificial atmosphere The operation of measuring and recording the concentration of (i.e., the second concentration data) can be performed.

In the first measuring step (step 203) and the second measuring step (step 204), the concentration of the fine dust may be measured by the concentration meter 141, the image recorder 142, or the like, as described above.

When the sample holder 132 on which the sample 132b is mounted is sealed and fine dust flows into the chamber housing 111, the concentration meter 141 creates an artificial atmosphere inside the chamber housing 111 by the fine dust. Until it is created (step 203), and when the sample holder 132 is opened due to the creation of an artificial atmospheric environment, while fine dust is adsorbed to the sample 132b (step 204), the inside of the main body 110 The measured value of the dust concentration is measured in real time, and can be output to a display (not shown) provided in the concentration measuring instrument 141 or the like.

That is, it can be measured by a light scattering (DLS) method in which the frequency of the pulse signal of the scattered light received from the particles is proportional to the density of the particles, and is provided in a form that can analyze the concentration of fine dust in real time. Can be.

In addition, the adsorption rate of fine dust may be different depending on the type of sample 132b mounted on the sample holder 132, so that fine dust is sufficiently adsorbed to the sample 132b so that the fine dust is no longer adsorbed. Sufficient time can be given to reach the state.

On the other hand, since the fine dust concentration measured by the concentration meter 141 is measured in real time and output to the display, there is a limit to recording the measured value of the concentration in real time. By recording the measured value of the fine dust concentration as an image, quantitative analysis of the fine dust concentration can be performed through the recorded data.

A step of calculating the fine dust protection rate of the sample 132b is performed using the first concentration data recorded in the first measuring step and the second concentration data recorded in the second measuring step (step 205).

Prior to calculating the fine dust protection rate for the sample 132b, quantitative analysis may be performed on the first concentration value and the second concentration value.

That is, when the sample holder 132 is closed, the rate at which the introduced fine dust spreads over time, the concentration value of the fine dust and the change in the concentration value accordingly, and the like, when the sample holder 132 is open, Accordingly, as fine dust is adsorbed to the sample 132b, the concentration value and the concentration value of the fine dust remaining inside the body part 110 change, the rate of decrease of the fine dust concentration value, and the difference in the adsorption rate according to the type of the sample 132b. Quantitative analysis to analyze the etc. may be preceded.

After the quantitative analysis of the first concentration data and the second concentration data is completed, the fine dust protection rate of the sample 132b may be calculated in the following manner.

[Fine dust defense rate evaluation formula]

In the above calculation formula, the reference concentration of fine dust in the chamber housing refers to the first concentration data recorded in the first measurement step, and the fine dust concentration of the experimental group refers to the second concentration data recorded in the second measurement step.

The fine dust protection rate is a value expressed as a ratio expressed by observing the behavior of fine dust in comparison to the reference concentration of fine dust, and converting it into a numerical value.If it is 100% or less, it can be determined that fine dust is adsorbed to the sample 132b It can be determined that the closer to the reference value, the higher the defense rate of the sample 132b against fine dust.

Subsequently, a post-processing step of discharging the fine dust remaining inside the main body 110 to the outside is performed (step 206).

As described above, a post-processing step is performed by the cleaning unit 150 to prevent contamination of the main body 110, the laboratory, etc. due to residual fine dust by removing fine dust inside the main body 110. Can be.

In the above description, various embodiments of the present invention have been presented and described, but the present invention is not necessarily limited thereto, and those of ordinary skill in the art to which the present invention pertains, within the scope of the technical spirit of the present invention.
