Description

VARIABLE WHITE SMOKE REDUCTION APPARATUS}

The present invention relates to a variable white smoke reduction device, and more specifically, to a variable white smoke reduction device with excellent usability by adjusting the rotation angle of a collection member that filters white smoke vapor in response to white smoke discharge conditions.

The smoke commonly seen in factory chimneys is a large amount of steam commonly generated and discharged at industrial sites, and is harmless to the human body, but ordinary people recognize it as harmful smoke. This smoke is white smoke that is generated when moisture contained in high-temperature exhaust gas is discharged through the chimney and mixes and condenses when in contact with cold external air. White smoke is mostly composed of water vapor, contains no pollutants, and automatically disappears after a certain period of time.

Meanwhile, due to the perception that white smoke is harmless to the human body but pollutants generated during factory operation are emitted, various studies have been conducted in recent years to reduce white smoke. In particular, the demand for white smoke reduction devices to reduce the visual aversion caused by white smoke and to recover water lost due to evaporation is rapidly increasing.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings. However, the spirit of the present invention is not limited to such embodiments, and the spirit of the present invention may be proposed differently by adding, changing, or deleting components constituting the embodiments, but this is also included in the spirit of the invention. It will happen.

Referring to FIG. 1, the variable white smoke reduction device 1 according to a preferred embodiment of the present invention includes a body portion 10, a collection portion 20, and a control portion 30.

For reference, the variable white smoke reduction device 1 described in the present invention is a device for filtering water vapor from white smoke (S), which is a large amount of white steam generated and discharged at industrial sites, and discharging it as gas (G).

White smoke (S) flows into the body portion (10) and is discharged as gas (G). This body portion 10 is formed on one side with an inlet 11 through which white smoke (S) flows in and an outlet 12 through which gas (G) is discharged, and a space is provided inside for the white smoke (S) to pass through. do. That is, the body portion 10 may have a hollow tube shape with an empty interior.

For reference, in the illustration of FIG. 1, the body portion 10 is illustrated as having a rectangular parallelepiped shape with the inlet 11 and the outlet 12 facing each other, but the present invention is not limited thereto. For example, a modification in which the body portion 10 has a cylindrical shape or the inlet 11 and the outlet 12 are provided so as not to face each other is also possible. If the inlet 11 and the outlet 12 do not face each other with respect to the body 10, a fan (not shown) is used to guide the white smoke (S) flowing into the inlet 11 toward the outlet 12. ) may be provided.

The collecting part 20 is provided to include a plurality of collecting members 21 stacked on each other based on the direction in which the white smoke (S) passes inside the body part 10, and collects water vapor contained in the white smoke (S). do. That is, the collection unit 20 reduces the white smoke (S) by collecting water vapor from the white smoke (S), and the white smoke (S) with the collected water vapor is discharged as gas (G).

As shown enlarged in FIG. 1, the collection unit 20 includes a plurality of collection members 21 stacked so that they face each other in the plane direction. These plurality of collecting members 21 are each provided in a micro-lattice structure and can each rotate in the plane direction about the rotation axis C. The surface direction rotation of the plurality of collecting members 21 will be described in more detail later along with the configuration of the control unit 30.

A plurality of collecting members 21 are stacked in a helical stack structure, and each layer of collecting members 21 is provided in a unit cell lattice structure as shown in FIG. 2 . In this embodiment, it is exemplified that the unit cell lattice structure of each of the plurality of collecting members 21 is a square mesh structure. In the illustration of FIG. 2, the collection member 21 is shown and illustrated as having a total of 64 unit cells of 8 x 8, but this is an example for explanation of the collection member 21 and is not a limitation. The shape and number of unit cells constituting the collecting member 21, and each length and thickness constituting the unit cells can be modified in various ways.

The plurality of collection members 21 constituting the collection unit 20 are rotated about the rotation axis C based on the reference line L as shown in (a) to (c) of FIG. 2. In Figure 2 (a), the collecting member 21 is shown in a state in which the collecting member 21 is not rotated about the rotation axis C with respect to the reference line L, and in Figure 2 (b), the collecting member 21 is shown as the reference line. A state in which the plane is rotated at a first angle θ1 about the rotation axis C based on the line L is shown. In addition, (c) of FIG. 2 shows a state in which the collection member 21 is rotated about the rotation axis C at a second angle θ2 with respect to the reference line L. Here, the first angle θ1 shown in FIG. 2 may be approximately 15°, and the second angle θ2 may be approximately 30°.

For reference, in FIG. 2, only one collecting member 21 is shown for convenience of explanation, but a plurality of collecting members 21 are stacked so as to face each other in the plane direction. Therefore, when any one of the plurality of collecting members 21 is rotated at the first or second angle θ1 and θ2 as shown in Figures 2 (b) and (c), the collecting members laminated on the next layer ( 21) is again rotated by the first or second angle θ1 and θ2 with respect to the neighboring collecting member 21, and this rotation of the collecting member 21 is repeated for each layer. As a result, each of the plurality of collecting members 21 serves as a basic layer of a micro lattice structure, and provides a collecting part 20 of a helical laminated structure that is stacked by rotating at a certain angle each time a unit layer is added.

Meanwhile, the plurality of collecting members 21 according to an embodiment of the present invention are collected in each layer based on the stacking direction parallel to the direction from the inlet 11 of the body 10 to the outlet 12. ) are rotated in the same direction. In the illustration of FIG. 2, the collecting member 21 is rotated counterclockwise with respect to the reference line L, but it is natural that it can also be rotated clockwise.

The control unit 30 controls the angle at which the plurality of collecting members 21 are rotated in a plane based on the rotation axis C of the plurality of collecting members 21 according to the external environment in which the body portion 10 is provided. Here, the control unit 30 compares the temperature difference between the temperature inside the body 10 and the temperature outside the body 10 and the relative humidity outside the body 10 with the preset reference value, respectively, and compares the white smoke ( The rotation angle θ of the plurality of collecting members 21 is controlled in conjunction with the amount of S) generated. This control unit 30 can rotate the rotation angle θ of the plurality of collecting members 21 so that it gradually becomes smaller than 45° as the amount of white smoke S generated gradually becomes larger than the reference value.

For reference, when the temperature difference between the inside and outside of the body 10 is large or the relative humidity outside the body 10 is relatively high, the amount of white smoke (S) generated increases. Conversely, when the temperature difference between the inside and outside of the body 10 is low or the relative humidity outside the body 10 is relatively low, the amount of white smoke (S) generated is reduced. That is, the control unit 30 controls the surface rotation angle θ of the plurality of collecting members 21 according to the amount of white smoke S generated.

The control unit 30 detects the generation rate of white smoke (S) by comparing the temperature difference and relative humidity with a preset reference value. If the generation rate of white smoke (S) is greater than the preset reference value by detecting the temperature difference and relative humidity, a plurality of collection members ( 21) Rotate the rotation angle (θ) to an angle close to O° (0°≤θ≤45°). In this embodiment, as shown in FIGS. 3 and 4, the control unit 30 rotates the angle for each layer of the plurality of collecting members 21 to 0°, 15°, and 30° according to the generation rate of white smoke S. and 4 steps of adjustment to 45°. At this time, the rotation angle θ between the plurality of collecting members 21 controlled by the control unit 30 is an example, and can be variously changed to 3 steps, 5 steps or more instead of 4 steps, etc.

The white smoke (S) is a water vapor component that collides with the collecting members 21 while passing through the collecting unit 20, and the fine particles contained in the water vapor adhere to the collecting member 21 due to the wettability of the droplets and are collected. Therefore, when the control unit 30 controls the rotation angle θ at which the plurality of collecting members 21 are stacked in a mutual helical lamination structure and the lattice space between the plurality of collecting members 21 is adjusted, white smoke ( The collection rate of S) can be adjusted.

More specifically, as shown in Figure 3 (a) and Figure 4 (a), when the temperature difference between the inside and outside of the body portion 10 is not large and the generation rate of white smoke (S) is lower than the reference value, multiple collection The members 21 are stacked on each other in a non-rotated state. That is, when the generation rate of white smoke S is lower than the reference value, the rotation angle θ of the plurality of collecting members 21 is 0°. In this state, where the plurality of collecting members 21 are not rotated at a rotation angle θ of 0°, the micro lattice structures provided in each of the plurality of collecting members 21 communicate with each other, so that the collecting density is low. Therefore, in the case of Figure 3 (a), the reduction rate of white smoke (S) is very low due to the low collection rate because the micro lattice structures are interconnected, but the pressure drop within the collection unit 20 is very low because the fluid moves easily. .

Here, the pressure drop of the collection unit 20 refers to the pressure difference before and after passing through the collection unit 20. The smaller the pressure drop, the lower the filter performance of the collection unit 20. When the fluid containing white smoke (S) passes through the collection unit 20 having a helical laminated structure, if the lattice space between the collection members 21 is large, the fluid moves easily and the pressure drop is small.

As shown in Figures 3 (b) to (d) and Figure 4 (b) to (d), as the temperature difference between the inside and outside of the body portion 10 gradually increases and the relative humidity gradually progresses to a saturated moist air state, a plurality of collecting members (21) The rotation angle (θ) between them gradually decreases within the angle range greater than 0° and lower than 45°.

More specifically, in Figures 3(b) and 4(b), the plurality of collecting members 21 are rotated at a rotation angle θ of 45° each time a layer is added in the same direction, 3 (c) and (d) and 4 (c) and (d) show rotation angles (θ) of 30° and 15° each time a plurality of collecting members 21 are added in the same direction. ) are each rotated. As shown in Figures 3 (b) to (d) and Figure 4 (b) to (d), as the rotation angle (θ) between the plurality of collecting members 21 gradually decreases, the collecting member having a micro-lattice structure. (21) The range of overlap between them widens, increasing the collection density.

Therefore, as the rotation angle θ between the plurality of collecting members 21 decreases, the collection rate of water vapor contained in the white smoke (S) increases, and the white smoke (S) reduction rate also increases. However, as the rotation angle θ between the plurality of collecting members 21 decreases, the collection density of the lattice structure increases, which also increases the rate of pressure drop due to the complex structure. Accordingly, the control unit 30 selectively adjusts the reduction rate of white smoke (S) between the collection members 21 according to the temperature difference and relative humidity with the outside where white smoke (S) is discharged, thereby increasing the pressure due to an unnecessary increase in collection density. Drops can be prevented.

The white smoke reduction operation of the variable white smoke reduction device 1 according to the present invention having the above configuration will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, the control unit 30 detects the temperature and relative humidity outside the body 10 and controls the rotation angle θ of the collecting member 21 of the collecting unit 20 as shown in FIG. 2. do. More specifically, when the temperature difference and relative humidity with the outside are low and the generation rate of white smoke (S) is significantly low, the rotation angle (θ) of the plurality of collecting members 21 is set to 0°, as shown in (a) of FIG. 3. Control. Therefore, as shown in (a) of FIG. 4, the water vapor collection density of the plurality of collecting members 21 is very low, so the reduction rate of the white smoke (S) is relatively low, but the white smoke (S) cannot pass through the lattice space. This facilitates the flow of air passing through the body portion (10).

When the temperature difference and relative humidity between the inside and outside of the body 10 are higher than the reference value, the control unit 30 adjusts the rotation angle θ for each layer of the plurality of collecting members 21 to 45, as shown in (b) of FIG. 3. Adjust to °. As a result, the plurality of collecting members 21 are in a state in which the collection density is increased, as shown in (b) of FIG. 4, in which the micro lattice structure between the collecting members 21 is complex compared to the state in (a) of FIG. 4. . As the white smoke (S) passes between these collecting members (21), fine particles contained in the water vapor collide with and adhere to the collecting members (21), and the water vapor is discharged as the collected gas (G).

When the temperature difference and relative humidity between the inside and outside of the body 10 increase from (b) in Figure 3, the control unit 30 collects a plurality of collection members 21 as shown in Figure 3 (c) and Figure 4 (c). ) The rotation angle (θ) is adjusted to 30° for each layer. That is, when it is desired to increase the collection rate of white smoke (S) compared to (b) in Figure 3, the rotation angle (θ) of the plurality of collection members 21 is lowered to collect the white smoke (S) as shown in (c) in Figure 4. Increases density.

In addition, when the control unit 30 detects that the generation rate of white smoke (S) is higher through the temperature difference and relative humidity, the rotation angle (θ) for each layer between the plurality of collection members 21 as shown in (d) of FIG. 3 ) is adjusted to 15°. Therefore, as shown in (d) of FIG. 4, the plurality of collection members 21 overlap each other to maximize the collection density, so that the reduction rate of white smoke S can be controlled to the highest.

As described above, although the present invention has been described with reference to preferred embodiments, those skilled in the art may make various modifications and changes to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that you can do it.
