Description

Technical Field

[0001] The present invention relates to a fully automatic dust removal system that can remove dust, volcanic ash, etc. without replacement for a long time.

Background Art

[0002] Conventionally, there has been a demand for the proposal of a powerful dust removal device and a volcanic ash removal device to reliably protect important social infrastructure from the adverse effects of volcanic ash fall in volcanic eruptions, which are natural phenomena in Japan in particular. This is because it is necessary to protect major facility equipment from volcanic ash or fine dust in the atmosphere, to achieve BCP business continuity in case of emergency, and to protect security facilities of national security agencies. Therefore, the development of a dust removal device, that is, a fully automatic dust removal system, which is an air dust filter device that blocks volcanic ash and atmospheric dust and enables basic devices such as cooling of important equipment and facilities to always function normally, is urgently required as an issue. Here, the target facilities for the above requirements include, in addition to air conditioning cooling facilities and precision machinery facilities from nuclear power, power, communication, data centers to national security facilities, important facilities of airports - railways - local governments, hospitals, fire - police agencies, etc. Further, even overseas, in countries and regions with many deserts, there are already countries and regions where various devices are being adversely affected by dust. The necessity of the above - mentioned fully automatic dust removal system is considered to be high internationally, and it is judged to be an invention necessary in the future, especially in modern times when desertification is progressing rapidly. That is, as described above, desertification is progressing rapidly on a global scale, and protection from dust disasters and volcanic eruptions, etc., for security facilities, power, data center national agency facilities, airports, ports, police, fire public infrastructure facilities, factories, building air conditioners of enterprises, and general building air conditioners is essential. Furthermore, from the perspective of national security levels, it is becoming necessary to rank the level of protection at each stage, from important national facilities, companies, and factories to buildings and ordinary homes, and to build a system that can respond to the needs of each stage according to its rank. Here, if we hypothesize the following ranking for infrastructure protection targets in various organizations, S1 can be assigned to the national security sector, A1 to various important national institutions and the Cabinet Secretariat Crisis Management Headquarters, B1 to local government security headquarters and various important infrastructure facilities, and C1 to private companies, general buildings, and residential facilities. The present invention enables the construction of a fully automated dust removal system suitable for this rank. Furthermore, the dust removal system of the present invention, which can fully automatically control measures to protect against sandstorms and ashfall in times of emergency, is particularly valuable. This is because it simplifies the time and effort required for maintenance by workers, and also reduces the time and effort required for subsequent maintenance to maintain functionality.

[0006] According to this invention, in order to protect critical infrastructure from the adverse effects of ashfall from volcanic eruptions, a natural phenomenon in Japan, the invention addresses the need for various dust removal devices and volcanic ash removal devices. It addresses the challenge of developing a dust removal device, specifically a fully automatic dust removal system, which is an atmospheric dust filter device that blocks volcanic ash and atmospheric dust, thereby protecting major facilities and equipment from atmospheric volcanic ash or fine dust, ensuring business continuity in times of emergency (BCP), and protecting defense facilities of national security agencies, so that basic equipment such as cooling systems for critical equipment and facilities can always function normally.

The need for this fully automatic dust removal system is considered to be high internationally, particularly in countries and regions with large desert areas where sand and dust are already negatively impacting various types of equipment. This is especially true in today's rapidly progressing desertification environment, where it is considered a necessary invention. Furthermore, from the perspective of national security, this fully automatic dust removal system can meet the demand for a system that ranks the level of protection at each stage, from important national facilities, companies, factories to buildings and private homes, and provides a system that can respond to the needs of each stage according to their respective ranks.

Modes for Carrying Out the Invention

[0008] Hereinafter, the present invention will be described based on the embodiments shown in the drawings. FIGS. 1 to 4 are schematic configuration explanatory diagrams of a fully automatic dust removal system according to the first embodiment of the present invention. As understood from FIGS. 1 to 4, the configuration of the first embodiment is configured as a so-called vertical system, and includes a filter medium winding roller 1 provided upward and around which a filter medium 4 is wound in advance, a filter medium moving roller 2 provided at a distance downward from the filter medium winding roller 1, and a filter medium sticking roller set 6 provided between the rollers 1 and 2 and composed of a pair of filter medium sticking rollers 3 arranged with their positions shifted vertically on both horizontal diameter sides 5 of the two rollers 1 and 2. A filter medium sticking roller set stage 7 is formed by arranging a plurality of stages of the filter medium sticking roller set 6 at intervals between the two rollers 1 and 2. A filter medium 4 is zigzag-stuck to the filter medium sticking roller set stage 7 so as to be substantially wave-shaped. Tension control means 8 for controlling the sticking tension of the stuck filter medium 4, a filter medium winding means 9 for winding up the filter medium 4 that has passed through the filter medium sticking roller set stage 7 and the filter medium moving roller 2 from the filter medium winding roller 1, and cleaning means 10 (see FIG. 3) for cleaning the filter medium 4 that has passed through the filter medium sticking roller set stage 7 and the filter medium moving roller 2 from the filter medium winding roller 1.

[0009] Referring to FIG. 2, the upward filter medium winding roller 1 and the downward filter medium moving roller 2 are mounted between the vertical frames 11 of a frame body framed in a square shape by the vertical frame 11 and the horizontal frame 12 with the axial directions of the two rollers 1 and 2 in the horizontal direction. As shown in FIG. 2, by a pair of filter medium sticking rollers 3, a filter medium sticking roller set 6 is formed by setting a pair with a slight vertical shift on both sides 5 in the horizontal diameter direction of the filter medium winding roller 1 and the filter medium moving roller 2. That is, when the filter medium sticking roller 3 is provided at one end 5 in the horizontal diameter direction of the filter medium winding roller 1 and the filter medium moving roller 2, the filter medium sticking roller 3 is provided at the other end 5 in the horizontal diameter direction of the filter medium winding roller 1 and the filter medium moving roller 2 with a slight shift downward. And, the pair of filter medium sticking rollers 3 forms the filter medium sticking roller set 6. Further, a plurality of stages of the filter medium sticking roller set 6 are provided at a predetermined interval between the two rollers 1 and 2 to form a filter medium sticking roller set stage 7.

[0010] However, as can be understood from FIGS. 1 and 3, the filter medium 4 is zigzag-stuck to the filter medium sticking roller set stage 7 so that the filter medium 4 is substantially wave-shaped. Therefore, the sticking surface of the filter medium 4 zigzag-stuck to be substantially wave-shaped as described above constitutes the filter surface of the dust removing device for removing dust. Furthermore, the present invention provides a modification member 15 that can change the surface area of ​​the filter material 4, which forms the filter surface; in other words, it can expand or contract the surface area. That is, when volcanic ash accumulates on the filter material 4 on the filter surface and the pressure loss of the filter material 4 increases, the pressure loss value is detected, and based on the detected value, the modification member 15 is slid via the control unit 16 to expand the surface area of ​​the filter material 4 that forms the filter surface. As for the control to expand the surface area of ​​the filter material 4, as shown in Figure 3, for example, it is possible to widen the distance between the filter material application rollers 3 provided at both ends 5 in the horizontal diameter direction of the two rollers 1 and 2, that is, to slide the pivot rods 17 that support the multiple filter material application rollers 3 in the horizontal direction using the modification member 15, and to widen the distance between the pair of pivot rods 17. This control ensures that the surface area of ​​the filter surface of the filter material 4 can be reliably expanded.

[0011] Furthermore, by connecting a volcanic ash surface area automatic tuning function, or in other words, a device for detecting the pressure loss value of the filter media 4, to the control unit 16, for example, if the pressure loss of the air transport resistance of the filter media 4 on the filter surface exceeds a certain value, the control will automatically expand the distance between the pair of pivot rods 17 by a certain amount, thereby expanding the filter media area and saving air pressure loss. In Figure 3, the filter media winding means 9 is composed of a winding roller, but it does not necessarily have to be a winding roller; any member that can wind up the filter media 4 is acceptable. Furthermore, as shown in Figure 3, the filter media winding means 9 is configured such that its axial core 13 can move, for example, horizontally away from both rollers 1 and 2. Thus, by sliding the axial core 13, it also serves as a tension control means 8 that can apply or release tension to the filter media 4 attached by the filter media winding means 9.

[0012] In this embodiment, the cleaning means 10 is provided between the filter media moving roller 2 and the filter media winding roller 9. An auxiliary roller 18 is provided between the filter media moving roller 2 and the filter media winding roller 9. The cleaning means 10 could be a vibrator-type cleaning device that removes dust and other particles adhering to the filter media 4 by vibrating the filter media 4, or an air blow-type or liquid blow-type cleaning device that blows away dust and other particles adhering to the filter media 4. However, it is not limited to the above cleaning devices. To further elaborate on the configuration of the cleaning means 10, it may also be an automatic vibration vibrator device that detects the state of dust or volcanic ash adhering to the filter material 4 and operates accordingly, a high-pressure JET liquid spray cleaning device, an automatic shot air blow device, an automatic dry off blow device, and other cleaning means 10.

[0013] Furthermore, the control unit 16 may control the timing of cleaning the filter media 4 using a numerical value of the movement speed of the filter media 4, or it may control the timing of cleaning based on the degree of volcanic eruption, the inflow rate and density of volcanic ash, or it may automatically sense the degree of pressure loss of the filter media 4 and automatically feed back that value, and the control unit 16 may control the movement speed of the filter media 4 to an appropriate speed. Furthermore, while the cleaning means 10 is automatically cleaned by the cleaning equipment described above, the sand and dust blown away by the high-pressure cleaning shot equipment or pulse air shot blow equipment is collected and disposed of by the dust collection and disposal means 14, such as the blower dust collector shown in Figure 4. In other words, a cleaning method is employed in which dust and volcanic ash are sucked in and blown out. In addition, the blown-out sand and dust are washed and separated in the circulator spin pot in the washing water circulation tank 19, the air is discharged by the dust collector blower 20, and the sand and dust settle and fall into the tank water. The settled sand and dust are transported by the underwater belt 21 and discharged and solidified.

[0014] The properties of volcanic ash vary depending on the volcano, and cleaning methods include high-pressure shot dry cleaning and high-pressure water washing, but the dry method is considered to be less expensive. Furthermore, a system combining an automatic vibrator and a high-pressure pulse shot blow may be used as a dust removal device. Here, the automatic vibrator cleaning device is a cleaning unit that applies vibration to a filter material 4, such as polyester filament, attached between the two rollers 1 and 2, causing the volcanic ash adhering to the surface of the filter material 4 to vibrate, and simultaneously blows a shot blow (high-pressure air blow, pulse) onto it to shake it off. This mechanism involves vibrating the fine dust particles trapped on the filter material 4, such as a monofilament, to instantly lift them, and simultaneously applying a high-pressure pulse shot blow to blow away fine particles such as volcanic ash from the surface of the filter material 4.

[0015] Furthermore, a high-pressure jet spray cleaning device can be used to wash away any volcanic ash clogging the openings of the filter media 4 with high-pressure water. Furthermore, the surface of the filter media 4, such as a monofilament, which has been cleaned by the automatic shot-blow air cleaning device, can be struck with a pulse shot air gun to blow away the dirty water. Alternatively, an automatic dry-off blow drying device may be used to dry the surface of the filter material 4, such as a wet monofilament, with hot air before returning the filter material 4 to the roll line of the volcanic ash collection device. In a dust removal system employing a roll-type filter media 4 as in the present invention, the cleaning cycle can be either a single-sided cleaning method or a double-sided cleaning method. However, the single-sided method requires a certain length of filter media 4, while the double-sided method can be applied even when the length of filter media 4 is short. In this case, the system can be used, cleaned, and regenerated repeatedly. Furthermore, it is preferable to configure the motors that drive the filter media winding roller 1 and the filter media winding means 9 as synchronous motors, thereby eliminating at least a phase difference and enabling the transfer of the filter media 4. In addition, the synchronous motor drive allows the filter media 4 to rotate at the same angle and position at all times. Furthermore, it is advisable to install a feed roller, which is a so-called filter winding assist roller, between the filter winding roller 1 and the filter winding roller, which is the filter winding means 9, in order to distribute and reduce the tensile load mainly applied to the filter material 4. However, it is conceivable to configure the feed roller for assisting in winding the filter media in such a way that the filter media 4 is sandwiched between a pair of rollers from above and below. With such a configuration, the tensile load applied to the filter media 4 can be further distributed and reduced, thereby preventing the mesh (opening size), which is the opening of the filter media 4, from expanding.

[0016] Next, Figures 5 to 7 show a second embodiment. The second embodiment, as can be seen from the figure, is a so-called horizontal dust removal system in which a filter material winding roller 1 and a filter material moving roller 2, and a plurality of filter material attachment rollers 3 provided between these two rollers 1 and 2, are erected vertically. The configuration of the second embodiment can be substantially the same as that of the first embodiment. In the second embodiment, the difference is that the roller set 6 for attaching the filter media is not configured in multiple rows in the vertical direction, but rather in multiple rows of roller set columns 23 arranged in the horizontal direction. Furthermore, there may be differences in system dimensions between vertical and horizontal configurations. This is because horizontal configurations are more likely to be required for installation in locations with height restrictions. Furthermore, a characteristic of the horizontal system is that the filter media winding drive can be provided to both the filter media winding roller 1 and the filter media moving roller 2 or the filter media winding roller 9.

[0017] The drive member 22 performs the winding drive, making it easy to configure the cable for both right-handed and left-handed winding. Furthermore, the cleaning means 10, such as the automatic cleaning device, can be mounted on both sides as well as one side, allowing for installation according to the customer's specifications. Furthermore, in a single-sided automatic cleaning system, operation is completed by using the filter once, performing automatic cleaning, winding it up, and then using it again in reverse rotation. However, in a double-sided automatic cleaning system, it can be used, cleaned, wound up, used in reverse, cleaned and wound up, and reused indefinitely. Moreover, because it is used in both directions, cleaned, wound up, and used in reverse, even considering the repeated use of the expensive special filter media 4, it does not require a very long roll length, resulting in cost advantages.

[0018] Here, the horizontal dust removal system uses rollers 1 and 2 on both the left and right sides as axes of rotation and, during volcanic eruptions, handles the S, A, B, and C ranks, which are the same types as the vertical system, and can be controlled in the same way as the vertical system. For example, in the aforementioned S-rank specification, the drive members 22 are located on both the left and right sides in full specification, and if a synchronous motor or a synchronous chain and synchronous shaft gear drive is used, filter cleaning functions can be equipped on both connected sides, creating a structure in which winding and cleaning are processed simultaneously. In addition, reverse operation can be performed automatically without limit on the number of repetitions, and it has a synchronous rotary operation mechanism, making unmanned management possible in defense security facilities, etc. In the standard configuration, clockwise and counterclockwise rotation can be controlled automatically or manually, allowing for a more cost-effective system configuration. However, it is preferable to configure the motors that drive the filter media winding roller 1 and the filter media winding means 9, which are both synchronous motors, so that the filter media 4 can be transported with at least no phase difference. Furthermore, the synchronous motor drive allows the filter media 4 to rotate at the same angle and position at all times.

[0019] Furthermore, it is advisable to install a feed roller, which is a so-called filter winding assist roller, between the filter winding roller 1 and the filter winding roller, which is the filter winding means 9, in order to distribute and reduce the tensile load mainly applied to the filter material 4. However, it is conceivable to configure the feed roller for assisting in winding the filter media in such a way that the filter media 4 is sandwiched between a pair of rollers from above and below. With such a configuration, the tensile load applied to the filter media 4 can be further distributed and reduced, thereby preventing the mesh (opening size), which is the opening of the filter media 4, from expanding. Incidentally, in the vertical and horizontal dust removal systems according to the present invention, when using the system to process volcanic ash, the volcanic ash processing speed can be changed according to the amount of volcanic ash falling or the importance of the equipment. For example, the system can assign ranks such as S rank, A rank, B rank, and C rank, and control the processing speed of volcanic ash and other dust according to each rank or level of urgency, and all of this can be done fully automatically.

[0020] Here, if we hypothesize the following ranking for infrastructure protection targets in various organizations, we can consider the following rankings: S1 for national security sectors, A1 for various national critical institutions and the Cabinet Secretariat Crisis Management Headquarters, B1 for local government security headquarters and various critical infrastructure facilities, and C1 for private companies, general buildings, and residential facilities. The present invention enables the construction of a fully automated dust removal system suitable for this ranking. Here, we will explain how to deal with the rapid clogging of filter media 4. When there is strong wind blowing of volcanic ash, ashfall, or desert dust, rapid clogging of filter media 4 is expected, which will cause a rapid increase in pressure loss, a decrease in airflow, a cessation of heat exchange, and various other problems such as the shutdown of the air conditioning system. Therefore, in the S-rank specification, a sudden increase in the pressure drop value of filter media 4 is detected, and the filter area of ​​filter media 4 is automatically expanded through control. If the filter material 4 becomes a new surface and the pressure loss decreases, the support rod 17 is returned to its original position. This will cause the air pressure to increase. Furthermore, when the cleaning of the filter media 4 is completed, the pressure loss recovery (decrease) is automatically detected and the support rod 17 returns to its original position.

[0021] The above control system is configured to provide appropriate control for each rank, from S-rank (intended for national security facilities) to A-rank national critical facilities and B-rank industrial standard facilities. In particular, for general household use, it is C-rank, or economy rank, so many functions are removed, but the cost can be kept low. [Explanation of symbols]
