Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying illustrative drawings, and since these embodiments are examples, those of ordinary skill in the art to which the present invention pertains may be implemented in various different forms. It is not limited to the embodiment.

Referring to FIG. 1 , the non-exhaust system fine dust collecting system 100 includes a blocking film 1, a clean air generator 1-a, 1A, 7, 8, 9, and a fine particle collection device 1-b, 1- c, 2, 3, 4) and suction negative pressure generators 5 and 6 are included.

In particular, the non-exhaust system fine dust collection system 100 uses clean air together with the blocking film 1 to inhale all of the non-exhaust tire wear dust with an efficiency of 98.4% or more without being scattered outside due to the influence of the driving wind. Excellent collection performance is realized.

In addition, the non-exhaust system fine dust collection system 100 uses clean air together with the blocking film 1 to achieve 98.4% of the wear dust generated from the brake pads of the non-exhaust system caliper brake system without being scattered outside due to the influence of the driving wind. By inhaling all with the above efficiency, the fine particle collection performance is excellently realized.

Therefore, the non-exhaust system fine dust collection system 100 collects both the fine particles (PM10) and the ultra-fine particles (PM2.5) generated due to the wear of tires and brake pads, which are non-exhaust systems, and can accurately measure the generation amount. This can be implemented.

For example, the barrier film 1 has a structure that surrounds the tire of the non-exhaust system wheel 300-1 (refer to FIG. 8), and prevents the abrasion dust of the tire and brake pad from being affected by the driving wind in the space inside the barrier film. Make sure that the driving wind does not flow into the interior space.

For example, the clean air generator (1-a, 1A, 7, 8, 9) includes a clean air supply inlet (1-a), a clean air supply hose (1A), a filter box (7), and a blower fan (8). and a generator 9 . In this case, the clean air supply inlet 1-a is provided on one side of the blocking film 1 and is connected to the clean air supply hose 1A. The filter box 7 supplies clean air from which foreign substances are removed to the clean air supply hose 1A as clean air. The blowing fan 8 is driven under the control of a controller (not shown) to blow air to the filter box 7 . The generator 9 is a self-generator using gasoline fuel, and supplies power to the suction pump 6 and the blowing fan 8 .

In particular, the filter box 7 filters 99.7% of micro nanoparticles at about 10,000 LPM with an industrial HEPA filter.

For example, the fine particle collecting device (1-b, 1-c, 2, 3, 3a, 4) is a suction probe (1-b), an auxiliary suction probe (1-c) and a cyclone unit (, 2, 3) ,4) consists of In this case, the suction probe 1-b is provided on the other side of the blocking film 1 to collect the wear dust of tires and brake pads in the inner space of the blocking film 1 . The auxiliary suction probe (1-c) collects the wear dust of the brake pad and sends it to the suction probe (1-b).

In addition, the cyclone unit (, 2, 3, 4) is composed of a primary cyclone (2), a distribution pipe (3), a cyclone line (3a) and a secondary cyclone (4). In this case, the primary cyclone 2 collects particles having a diameter of 10 μm or larger at the bottom of the cyclone while discharging the remaining small particles to the top of the cyclone. The distribution pipe 3 is connected to the inlet of the secondary cyclone 4 while being connected to the outlet of the primary cyclone 2 with a cyclone line 3a to supply a flow rate to the secondary cyclone 4 . . The secondary cyclone 4 collects particles having a diameter greater than 2.5 μm at the bottom of the cyclone while discharging the remaining small particles to the top of the cyclone.

In particular, the distribution pipe 3 is a cyclone line 3a connected to the three outlets, and the flow rate is uniformly divided and distributed by 1/3 to each of the three secondary cyclones 4 . In addition, the primary and secondary cyclones 2 and 4 have the same structure and operation method as a general cyclone, except that the particle diameter to be collected is different.

For example, the suction negative pressure generator 5 and 6 includes a filter 5 and a suction pump 6 . In this case, the filter 5 collects fine particles smaller than 2.5 μm separated from the secondary cyclone 4 . The suction pump 6 sucks a flow rate required for the non-exhaust system fine dust collection system 100 such as tire/brake pad wear fine dust.

In particular, the filter 5 is an industrial HEPA filter, which filters 99.7% of micro nanoparticles at about 10,000 LPM. In addition, the suction pump 6 is controlled by a controller (not shown) to control the motor suction amount for isokinetic sampling.

In addition, the non-exhaust system fine dust collecting system 100 includes a data analyzer 200, and the data analyzer 200 is composed of a main server and a notebook computer or data processor connected thereto. Through this, the data analyzer 200 measures the weight of particles with a diameter larger than 10 μm of the primary cyclone 2 and particles with a diameter larger than 2.5 μm of the secondary cyclone 4, and collects fine dust in the non-exhaust system. The fine dust collection performance of the system 100 is analyzed.

In particular, the data analyzer 200 may replace a controller (not shown) with control functions for the blowing fan 8 and the suction pump 6 .

Meanwhile, FIGS. 2 and 3 illustrate the detailed configuration and fine dust collection performance of the blocking film 1 . In this case, the reason that the blocking film 1 is expressed in a shape with both sides open is to illustrate the internal space, and the actual shape consists of a shape in which only the lower part is partially open from a shape in which both sides are closed.

Referring to FIG. 2 , the blocking film 1 is sized to cover the diameter and width of the tire, and forms a book-shaped circular body with one open side spaced apart from both ends constituting the lower portion of the blocking film, and forms a lower portion of the book-shaped circular body. A clean air supply inlet (1-a) is formed at one end of both ends, while a suction probe (1-b) is formed at the other end.

In particular, the lower portion of the book-shaped circular body is formed to be spaced apart by about 8 cm from the road surface or the tire tread with the blocking film 1 covering the tire.

For example, the clean air supply inlet (1-a) has a rectangular parallelepiped shape, is located at one end of the lower portion of the book-shaped circular body, and has a plurality of protruding ports (eg, three ports) to supply a plurality of clean air Hose 1A (eg, three clean air supply hoses) is connected.

In particular, the clean air supply inlet (1-a) forms a plurality of protruding ports outside the blocking film (1), so that the clean air supply hose (1A) is connected from the outside of the blocking film (1).

From this, the blocking film 1 can form an air curtain with clean air coming out of the clean air supply inlet 1-a to the lower part of the book-shaped circular body.

For example, the suction probe 1-b has a funnel shape and is located at the other end of the lower portion of the drum-shaped circular body, and has a wide funnel entrance inside the blocking membrane 1 and a narrow funnel entrance into the blocking membrane 1 ) and connected to the cyclone line (3a).

Therefore, the clean air supply inlet 1-a and the suction probe 1-b face each other and are integrally formed on the blocking film 1, and are positioned about 8 cm apart from the road surface or the tire tread. In particular, the clean air supply inlet 1-a and the suction probe 1-b are formed directly on the blocking film 1 to form an integrated structure or are fixed by welding to form an integrated structure.

Referring to FIG. 3 , while the barrier film 1 introduces clean air into the clean air supply inlet 1-a, the suction probe 1-b removes tire wear dust generated in the inner space of the barrier film 1 finely. The ability to collect into particles is exemplified.

3(A) shows the 10 μm generated in the tire with the clean air supply inlet (1-a) being directly used with the barrier film 1 wrapped around the tire at a distance of about 8 cm from the road or tire tread. It indicates a state in which the suction probe 1-b sucks air at 3600 LPM (Liter per minute) so as to suck all of the following fine particles.

3(B) shows that the vehicle travels at a constant speed of about 40 km/h. And Figures 3(C) and (D) show the results of schematically showing the fine particle collection performance of the blocking film (1). As described above, the simulation result confirms that 98.3% of the fine particles in the tire with a diameter larger than 10 μm can be sucked by using the Fixed Grid Method as a vehicle simulation technique and attaching it to the tire and blocking the external flow.

Meanwhile, FIGS. 4 and 5 illustrate the configuration of the auxiliary suction probe 1-c applied to the brake caliper and the fine dust collection performance of pad wear.

Referring to FIG. 4 , the auxiliary suction probe 1-c includes a collection body 1-ca and an outlet port 1-cb, and is mounted on a brake disk of a wheel to which a tire wrapped with a barrier film 1 is coupled. connected to the brake caliper. In this case, the auxiliary suction probe 1-c is located below the brake caliper.

For example, the collecting body 1-ca surrounds the brake disc in a “U” cross-sectional shape, and the outlet 1-cb has a port structure protruding from one wall of the collecting body 1-ca.

Therefore, the auxiliary suction probe (1-c) collects the wear dust of the brake pad from the lower side of the brake caliper to the collecting body (1-ca) of the “U” cross-section, and the pad fine particles collected in the space of the “U” cross-section. The particles are discharged from the outlet (1-cb) positioned downward toward the road surface so that the suction probe (1-b) can collect it.

Referring to FIG. 5 , the performance of the auxiliary suction probe 1-c collecting pad microparticles collected by the suction probe 1-b in the inner space of the blocking film 1 is exemplified.

Figure 5 (A) shows the auxiliary suction probe (1-c) through the outlet (1-cb) while collecting the pad microparticles by positioning the collecting body (1-ca) below the brake caliper mounted on the brake disc. It represents a state in which the collected pad fine particles are discharged into the inner space of the blocking film (1). In this case, the suction probe 1-b sucks air at 3600 LPM (Liter per minute).

Fig. 5(B) shows that the vehicle brakes repeatedly. And Figures 5 (C) and (D), the auxiliary suction probe (1-c) shows a schematic result of the collection performance of the suction probe (1-b) for the pad fine particles collected by the probe (1-c).

In this way, by using the Fixed Grid Method as a vehicle simulation technique, the auxiliary suction probe (1-c) is positioned below the brake caliper to collect the pad fine particles, and 98.4% of the pad fine particles with a diameter larger than 10 μm can be sucked. This is confirmed by the simulation results.

Meanwhile, FIG. 6 illustrates the detailed configuration of the primary and secondary cyclones 2 and 4 and the distribution pipe 3 connecting them.

For example, the distribution pipe 3 includes a cylindrical distribution body 3-1, an inlet 3-2 protruding from one side of the distribution body 3-1, and the other side of the distribution body 3-1. It consists of three outlets (3-3) protruding from the.

Therefore, the distribution pipe 3 is connected to the primary cyclone 2 by a cyclone line 3a connected to the inlet 3-2, and a cyclone line 3a connected to each of the three outlets 3-3. Each leads to three secondary cyclones (4). In particular, since each of the three outlets constituting the outlet 3-3 has the same diameter, the flow rate is uniformly distributed to each of the three secondary cyclones 4 by 1/3.

From this, the distribution pipe 3 sucks fine particles at 3600LPM from the primary cyclone 2 through one inlet 3-2, and then through three outlets 3-3 to 1200LPM secondary cyclone. It is supplied to the clone (4).

For example, the primary cyclone 2 inhales fine particles in an aerosol form at 3600LPM from the inhalation probe 1-b and turns them inside the cyclone, and depending on the size of inertia generated thereby, the size is 10 μm or more Large fine particles settle to the bottom of the cyclone, while relatively small particles less than 10 μm in size are discharged to the top of the cyclone.

Therefore, the primary cyclone 2 collects fine particles larger than 10 μm to the lower part of the cyclone while discharging the remaining particles smaller than 10 μm to the upper part of the cyclone, thereby first separating the size of tire and pad fine particles.

For example, the secondary cyclone 4 inhales fine particles in an aerosol form at 1200LPM through the distribution pipe 3 and turns it inside the cyclone, and depending on the size of inertia generated thereby, the size is 2.5 μm or more Large particles settle to the bottom, while relatively small particles less than 2.5 μm in size are discharged to the top of the cyclone.

Therefore, in the secondary cyclone 4, fine particles larger than 2.5 μm are collected at the bottom of the cyclone, while the remaining fine particles smaller than 2.5 μm are discharged to the top of the cyclone to separate the size of tire and pad fine particles. give.

In particular, the fine particles larger than 10 μm collected by the primary cyclone 2 and the fine particles larger than 2.5 μm collected by the secondary cyclone 4 are measured by the data analyzer 200 by measuring the mass of the collected particles. Weigh the 2.5~10μm fine particles.

Meanwhile, FIGS. 7 and 8 exemplify the vehicle 300 in which the vehicle-generated fine dust removal method using the non-exhaust system fine dust collection system 100 is performed. In this case, the control subject is a controller (not shown) and/or the data analyzer 200 , and the control objects are the suction pump 6 , the blowing fan 8 and/or the generator 9 .

And the fine dust collection system 100 mounted on the vehicle 300 includes the blocking film 1 described with reference to FIGS. 1 to 6 , the clean air generators 1-a, 1A, 7, 8, 9, and the fine It is composed of a particle collecting device (1-b, 1-c, 2, 3, 4) and a suction negative pressure generating device (5, 6). In particular, the controller (not shown) and/or the data analyzer 200 may be mounted in the interior space 300 - 2 of the vehicle 300 .

Referring to FIG. 7 , the vehicle-generated fine dust removal method starts with vehicle driving and operation of a blowing fan in S10, and clean air is supplied in S20.

Referring to FIG. 8 , the clean air supply hose 1A is connected to the clean air supply inlet 1-a while the blocking film 1 wraps the tire of one of the four wheels 300 - 1 . The clean air supply hose (1A) is connected to the filter box (7), the filter box (7) is connected to the blowing fan (8) driven by the generator (9), and the filter box (7)/blowing fan (8) / The generator (9) is arranged on one side in the indoor space (300-2).

Therefore, in the vehicle driving and blowing fan operation (S10), the blowing fan 8 is driven by the generator 9 while the vehicle 300 is driving, and the filter box 7 is a foreign substance in the air sent from the blowing fan 8. It is converted to clean air from which air has been removed. In this case, the generator 9 is installed inside the vehicle as a separate power supply source for the operation of the blowing fan 8 and the suction pump 6 .

Then, the clean air supply (S20) is made by introducing clean air into the clean air supply inlet (1-a) through the clean air supply hose (1A) connected to the filter box (7), and the clean air is approximately An air curtain is formed in the lower portion of the blocking film 1 spaced apart by 8 cm to prevent the traveling wind from entering the four space of the blocking film 1 . In this case, the clean air is air generated by passing the air generated by the blowing fan 8 through the industrial HEPA filter of the filter box 7 differently from the running wind.

Then, the vehicle-generated fine dust removal method performs the operation of the suction pump of S40 for the generation of fine particles of tire/brake wear in S30.

Referring to FIG. 8 , the cyclone line 3a is connected to the blocking film 1 by a suction probe 1-b provided opposite to the clean air supply inlet 1-a. And the cyclone line (3a) leads to the distribution pipe (3) through the primary cyclone (2) located in the indoor space (300-2), and three secondary cyclones in the trunk (300-3) (4), a filter (5) and a suction pump (6) are arranged.

Therefore, the generation of fine particles of tire/brake wear ( S30 ) is caused by fine particles of tire wear dust generated from the tire rubbing against the road surface while the vehicle 300 is running and the brake pad rubbing against the brake disk during braking of the vehicle 300 . It refers to the fine particles of pad wear dust generated in In this case, the fine particles of the pad wear dust are collected at the auxiliary suction probe 1-c connected to the brake caliper of the tire wrapped with the barrier film 1, and then collected at the suction probe 1-b.

Then, the suction pump operation (S40) creates a pressure lower than the atmospheric pressure on the ground in the suction probe (1-b) to suck a flow rate at 3600 LPM, and the suction flow rate is a cyclone line connected to the suction probe (1-b) Exit to (3a). In this case, the suction flow rate of the suction probe 1-b is the fine particle of the tire/brake.

Subsequently, in the vehicle-generated fine dust removal method, the fine particle cyclone analysis step of S50 to S90-2 is performed.

Specifically, the fine particle cyclone analysis (S50 ~ S90-2) is the first cyclone inflow step of S50, the fine particle separation step of S60 ~ S60-1, the secondary cyclone inflow step of S70, S80 ~ S90-2 of fine particle separation/analysis step.

For example, the primary cyclone inflow (S50) is made through the primary cyclone (2), and the primary cyclone (2) is connected to the suction probe (1-b) through the cyclone line (3a). The suction probe 1-b collects the fine particles of the tire/pad sucked.

Then, in the separation of the fine particles (S60 to S60-1), the small particles smaller than 10 μm among the fine particles collected through the primary separation step of S60 are discharged to the upper part of the cyclone of the primary cyclone (2). On the other hand, among the collected fine particles, large fine particles having a size of 10 μm or more are sedimented to the bottom of the cyclone of the primary cyclone (2), and the collection step of S60-1 is completed. In this case, in the step of S60, the fine particles collected through the function of the primary cyclone 2 are separated by size classification.

For example, the secondary cyclone inflow (S70) is made through the secondary cyclone (4), and the secondary cyclone (4) is a cyclone from the distribution pipe (3) connected to the primary cyclone (2). Small particles of less than 10 μm in size discharged by the primary cyclone 2 are collected through the clone line 3a. In this case, since the secondary cyclone 4 is composed of three secondary cyclones 4, the flow rate of the distribution pipe 3 is evenly divided by 1200LPM by 1/3 through the three outlets 3-3. get distributed

Then, the fine particle separation/analysis (S80 ~ S90-2) goes through the secondary separation step of fine particles of S80, and the fine particles larger than 2.5 μm are sedimented to the bottom of the cyclone of the secondary cyclone (4), While the cyclone collecting and weighing step is completed, the remaining fine particles smaller than 2.5 μm are discharged to the upper part of the cyclone of the secondary cyclone (4) and collected by the filter (5), thereby collecting and weighing the filter of S90-2 completed in steps In this case, separation by size classification of the collected fine particles is made through the function of the secondary cyclone 4 itself. In this case, in the step of S80, the fine particles collected through the secondary cyclone 4's own function are separated by size classification.

Finally, the cyclone collection and weight measurement (S90-1) is performed in the data analyzer 200 by collecting the fine particles of 2.5 to 10 μm in size that have settled under the cyclone of the secondary cyclone 4, and the filter The collection and weight measurement (S90-2) is performed in the data analyzer 200 by collecting the fine particles having a size of less than 2.5 μm collected in the filter 5 .

As described above, in the vehicle-generated fine dust removal method using the non-exhaust fine dust collection system 100 applied to the vehicle 300 according to the present embodiment, one side of the barrier film 1 surrounding the tire at a predetermined distance from the lower part of the tire. The air curtain is formed by the air injection of the clean air supply inlet (1-a) from the lower part, and the fine particles of the tire and brake pad are sucked with the suction probe (1-b) from the other lower part, and the fine particles are first After the two-step size separation and collection of fine particles by the cyclone (2) and the secondary cyclone (4) are performed, the amount of fine dust generated by the non-exhaust system is accurately identified by weight measurement by the data analyzer 200, so that the blocking film (1) ) to minimize the amount of tire dust and brake pad abrasion fine particles that are lost due to the driving wind by blocking the driving wind. By inhaling the entire amount of particles, it is possible to classify/collect high-efficiency fine particles (PM10) and ultra-fine particles (PM2.5).
