Description

TECHNICAL FIELD

[0001] The application relates to the technical field of pipeline descaling, corrosion prevention and microbial killing, in particular to a terahertz micro-nano composite tuning sound field device. BACKGROUND

[0002] The circulating cooling water system is an important part of industrial production facilities, and is widely used in the petroleum chemical industry, power, metallurgy, medicine, textile, papermaking, food, machinery, automobile manufacturing, electronics, cloud data center and other industries. The circulating cooling water system using water as the heat exchange medium is widely used. The amount of circulating cooling water usually accounts for more than 70% of the total amount of industrial water, so the treatment of industrial circulating cooling water is the most important in industrial production. Because the circulating cooling water has the characteristics of large water consumption, easy to cause scaling, corrosion, breeding of microorganisms and the like, and the scaling thermal resistance and the heat transfer coefficient are inversely related, not only brings safety hazards to production, but also causes huge energy loss and economic loss (for example, 1.5mm CaCO3 scale will increase 10%~20% of energy consumption, 12mm scale will increase about 70% of energy consumption, and 25mm scale can reduce the efficiency of the equipment by 95%. For example, CaCO3 scale is the main scale deposited on the heated surface, which is hard, dense, strong in adhesion and large in thermal resistance. In China, about ten thousand heat exchangers are scrapped every year due to this, causing incalculable economic losses). Therefore, the term of circulating cooling water treatment has a special meaning. The circulating cooling water treatment is different from the general sewage treatment and the conventional water treatment. The circulating cooling water treatment is mainly a series of water quality treatment processes for the characteristics of circulating cooling water, which mainly includes scale inhibition, corrosion inhibition and control of microbial (bacteria, algae and fungi) breeding. It has both conventional and special properties.

[0003] The traditional treatment method is to add scale inhibitors, biocides, corrosion inhibitors and other chemical agents to the circulating cooling water system. The addition of these agents not only requires a high and continuous cost, but also pollutes the environment, bringing huge secondary water treatment costs to industrial enterprises. In order to comply with the main theme of green transformation and green development, the industry considers using physical water treatment methods such as ultraviolet rays, ultrasonic waves, magnetic fields and electric fields to treat pipeline descaling, but due to some shortcomings, it has not been widely applied.

[0004] Terahertz micro-nano composite tuned sound field devices are used for descaling, corrosion prevention, and microbial elimination in circulating cooling water systems. This technology requires no electricity, making it a green and low-carbon approach, and has achieved good results in practice. Structurally, terahertz micro-nano composite sound field devices include tower-shaped, conical, and ball-and-bar shaped devices. In use, multiple devices are typically evenly distributed on the outer wall of the pipe to ensure effective descaling, corrosion prevention, and microbial elimination. However, current methods for fixing these devices mainly rely on binding, which makes accurate positioning difficult when installing multiple devices.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0030] In the following description, numerous specific details are provided to provide a thorough understanding of the present application. One of ordinary skill in the art will recognize, however, that the application can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, and so forth are not shown or described in detail in order to avoid obscuring aspects of the present application.

[0031] The descaling, anti-corrosion and microorganism-killing principles of the terahertz micro-nano composite acoustic field device are as follows: The terahertz micro-nano composite acoustic field device adopts terahertz integrated chip and micro-nano integrated technology to realize a series of important functions such as generation, amplification, frequency multiplication and filtering of terahertz signals, and contains a composite tuning spiral wave acoustic field (including elastic wave phonon spin) formed by terahertz and GaAs titanium alloy micro-nano material lattice to generate super-power spiral acoustic waves, which pass through the pipe wall into the fluid, so that the fluid molecules (water molecules and substances in them) are activated by the same frequency vibration, and multiple action effects such as molecular vibration and depolymerization effect, mechanical and cavitation effect, lattice vibration and electrochemical effect are generated in the fluid. Among them, through the molecular vibration and depolymerization effect, the substance molecules can be freed from the van der Waals force between the molecules, and cannot accumulate to form large-scale hardened scale (the same can prevent organic matter from self-aggregation), so that they form flocculent salt scale particles in the fluid and are carried away by the fluid. Microorganisms (bacteria, algae and fungi) are greatly affected by the mechanical effect, cavitation effect and micro-jet shear of the super-power acoustic waves generated by the same frequency vibration, such as inducing the rearrangement of cell membrane lipid molecules, forming nanoscale pores (cell membrane perforation), leading to the leakage of intracellular substances, and the spatial conformation change of microbial enzymes, the destruction of enzyme activity, etc., so as to make the microorganisms die or their growth be inhibited; the movement of the fluid also makes the biological slime not adhere to the inner surface of the equipment and pipeline to cause harm (such as microbial slime can cause under-deposit corrosion). The lattice vibration and electrochemical effect is to excite the lattice vibration of the oxide film, rearrange the defects (such as oxygen vacancies) in the passivation film, form a more continuous nanoscale protective layer, and provide a high-efficiency and environmentally-friendly solution for pipeline protection through multi-mechanism synergistic effect such as electrochemical interference and microbial inhibition, thereby playing a role in pipeline corrosion and inhibition. At the same time, the phonon wave (also known as composite tuning spiral wave acoustic field) generated by the terahertz micro-nano composite acoustic field device can produce fine ripples in the propagation process, has strong penetration and directivity, and is easy to concentrate acoustic energy, and can propagate several kilometers in water, so it can replace chemical agents for pipeline descaling, anti-corrosion and microorganism-killing, thereby solving the problems of circulating cooling water scaling, microbial breeding and pipeline corrosion prevention.

[0032] At present, in order to ensure the effects of descaling, microorganism-killing and pipeline corrosion prevention, when using the conical cylindrical terahertz micro-nano composite acoustic field device, the ball rod terahertz micro-nano composite acoustic field device or the tower terahertz micro-nano composite acoustic field device, a plurality of (for example, three) terahertz micro-nano composite acoustic field devices are usually needed to be uniformly distributed on the outer wall of the pipeline. However, at present, the fixing of the conical cylindrical terahertz micro-nano composite acoustic field device and the ball rod terahertz micro-nano composite acoustic field device mainly relies on binding fixing, and for the case of multiple terahertz micro-nano composite acoustic field devices, it is difficult to realize accurate positioning and installation, and further difficult to ensure the uniformity of the distribution of the multiple terahertz micro-nano composite acoustic field devices, which will lead to the reduction of the descaling effect.

[0033] Therefore, the application provides a terahertz micro-nano composite tuning sound field device.

[0034] In order to more clearly describe the technical solutions in the application, the following will be described in the form of specific embodiments.

[0035] Embodiments

[0036] As Figures 1-3 , the application provides a terahertz micro-nano composite tuning sound field device, which is applied to a circulating cooling water system pipeline and is specifically used for pipeline descaling, corrosion prevention and microbial killing. The device can be installed on the return water pipeline and the water outlet pipeline of the cooling tower in the circulating cooling water system, and also needs to be installed on the facilities equipped with side filtration treatment, thereby forming a regional "sound field" and effectively "covering" and acting on the whole pipeline system of the cooling tower.

[0037] The device comprises a terahertz micro-nano composite sound field device 5, a snap ring 2 and a fixing rod 6. The number of the snap ring 2 is two, and the two snap rings 2 are installed on the pipeline 1 in sequence along the extension direction of the pipeline 1. The fixing rod 6 is connected to the two snap rings 2 at both ends respectively. Each snap ring 2 is composed of two semicircular structures, and the two semicircular structures are detachably connected. The number of the fixing rod 6 is multiple, and the multiple fixing rods 6 are uniformly arranged on the pipeline 1 along the circumferential direction of the pipeline 1. The number of the terahertz micro-nano composite sound field device 5 corresponds to the number of the fixing rod 6 one by one, and each terahertz micro-nano composite sound field device 5 is installed on the corresponding fixing rod 6.

[0038] The fixing rod 6 can be connected to the two snap rings 2 in a detachable or non-detachable manner. For example, it can be fixed on the snap ring 2 in a welding manner. For another example, it can be fixed on the two snap rings 2 in a threaded connection manner. For another example, it can be fixed on the two snap rings 2 in a plug-in manner. In some implementation schemes of the embodiment, the snap ring 2 is provided with a connecting hole for connecting the fixing rod 6. The number of the connecting hole can be greater than the number of the fixing rod 6. In this way, the fixing rod 6 in the device can be conveniently increased according to actual needs. For example, 12 connecting holes can be uniformly distributed on the snap ring 2, so as to adapt to the application scenarios of 2, 3, 4, 6 and 12 terahertz micro-nano composite sound field devices 5.

[0039] The terahertz micro-nano composite sound field device 5 can be tower-shaped, conical cylinder-shaped or ball rod-shaped. In the embodiment shown in Figure 1 , 2 , the terahertz micro-nano composite sound field device 5 is tower-shaped. The conical cylinder-shaped terahertz micro-nano composite sound field device is shown in Figure 4The ball rod-shaped terahertz micro-nano composite acoustic field device is shown in the figure Figure 5 The ball rod-shaped terahertz micro-nano composite acoustic field device is shown in the figure

[0040] In this embodiment, the snap ring 2 is composed of two semicircular structures. In this case, a plurality of fixing rods 6 can be connected to the two semicircular structures respectively. Figure 1 In this embodiment, the number of fixing rods 6 is three, one fixing rod 6 is connected to one semicircular structure, and two fixing rods 6 are connected to the other semicircular structure.

[0041] In this embodiment, the two semicircular structures are detachably connected. For example, pin connection, clamping connection, threaded connection and the like can be used, which will not be described in detail.

[0042] The device structure of the above technical solution is simple, easy to install, and can realize accurate positioning and installation of a plurality of terahertz micro-nano composite acoustic field devices 5 outside the pipeline 1, so that they are evenly distributed in the circumferential direction of the outer wall of the pipeline, thereby helping to ensure the effects of descaling, corrosion prevention and microbial killing. And this way has good stability, can improve the fixing effect of the terahertz micro-nano composite acoustic field device 5, and ensure that the terahertz micro-nano composite acoustic field device 5 can play a long-term and stable role in descaling, corrosion prevention and microbial killing.

[0043] As shown in Figure 2 The inside of the snap ring 2 is provided with a buffer pad 8. The buffer pad 8 can be made of polytetrafluoroethylene (PTFE), that is, a material that has little effect on terahertz waves. By providing the buffer pad 8, damage to the outer wall of the pipeline 1 during installation of the snap ring 2 can be avoided. And by providing the buffer pad 8, the anti-slip effect between the snap ring 2 and the pipeline 1 can be improved, and the installation position of the terahertz micro-nano composite acoustic field device 5 can be prevented from shifting.

[0044] The way in which the terahertz micro-nano composite acoustic field device 5 is fixed on the fixing rod 6 can be selected according to actual needs. In the scheme of this embodiment, as shown in Figure 1 、 2 The terahertz micro-nano composite acoustic field device 5 is fixed on the fixing rod 6 by a strap 7. This way is convenient to fix, and can be convenient for disassembly and maintenance. Figure 1 、 2 Each terahertz micro-nano composite acoustic field device 5 is fixed by one strap 7. It can be understood that more straps 7 can be used to fix the terahertz micro-nano composite acoustic field device 5 to ensure the fixing effect, which will not be described in detail.

[0045] As shown in Figure 1 The terahertz micro-nano composite acoustic field device 5 is a conical cylinder, and the axis direction of the terahertz micro-nano composite acoustic field device 5 is parallel to the axis direction of the pipeline 1. This arrangement helps to improve the effects of descaling, microbial killing and pipeline corrosion prevention of the pipeline 1.

[0046] Please continue to refer to Figure 1, the terahertz micro-nano composite acoustic field device 5 is in the shape of a tower or a conical cylinder (the middle part is in the shape of a tower) Figure 1 It can be understood that the conical cylinder-shaped terahertz micro-nano composite acoustic field device 5 can be divided into an outer layer, an inner layer, and a middle layer, and the inner and outer layers are external energy absorption layers. By setting threads on the inner and outer sides (i.e., the inner side of the inner layer and the outer side of the outer layer), the absorption area of the inner and outer sides to photons can be increased, so that it can be applied to extremely weak light environment applications. In addition, this threaded design is also conducive to the emission of terahertz waves.

[0047] The middle layer material of the terahertz micro-nano composite acoustic field device 5 can be selected as needed. In an implementation not shown in the embodiment, the middle layer of the terahertz micro-nano composite acoustic field device 5 can use gallium arsenide (GaAs) composite micro-nano material. GaAs has a small effective mass of electrons, so the electron mobility is high, about 6 times that of silicon; its band gap is wide, 1.43 eV, and can work at high power and temperature; its Schottky barrier is high, 0.7-0.8V, which is conducive to the preparation of high-performance gate-controlled transistors; its saturation migration rate is high, which is conducive to working at higher frequencies. In addition, the most significant advantage of GaAs is that it has faster speed at the same power consumption; at the same speed, GaAs has lower power consumption. GaAs has relatively stable characteristics, and compared with the third generation of semiconductors, its manufacturing technology is mature and the price is reasonable, which makes GaAs successfully enter the mainstream semiconductor compound market. GaAs and titanium alloy composite micro-nano material can excite strong local electromagnetic field through interface and structure optimization, multi-field coupling and function integration, break through the performance limitation of single material, realize the directional enhancement or modulation effect of GaAs and titanium alloy composite module on terahertz wave effect, and thus be conducive to further improving the descaling effect.

[0048] It can be understood that the external energy absorption layer usually uses a thin film battery. The thin film battery can absorb light energy to generate photoelectron-hole pairs, under the action of the built-in electric field in the battery, the photoelectrons and holes are separated, the holes drift to the P side and the electrons drift to the N side, forming a photogenerated electromotive force and generating a current. In the embodiment, the external energy absorption layer of the terahertz micro-nano composite acoustic field device 5 is a GaAs micro-nano material light-sensitive thin film battery. The GaAs micro-nano material light-sensitive thin film battery has a large light absorption coefficient, good weak light effect, and low temperature coefficient, which helps to improve the energy absorption effect.

[0049] The inventor found in the research that, in order to better realize the effect of composite tuning sound field, it is necessary to arrange according to the characteristics of the circulating cooling water pipeline 1 (pipe diameter, length, water quantity, space, etc.), and usually need to be installed at appropriate positions on the return water pipeline 1 and the outlet water pipeline 1 of the cooling tower. If it is found in use that the current installation position is not the best, the terahertz micro-nano composite sound field device 5 usually needs to be disassembled and then reinstalled. In order to solve this problem, in the scheme of the embodiment, the device is designed as a movable type, so that when the current installation position is wrong, the position can be adjusted by moving the device on the pipeline 1 without disassembly. Specifically, in the scheme of the embodiment, the two ends of the two semicircular structures are detachably connected by bolts; as shown in Figure 3 , a plurality of fixing grooves 12 are uniformly arranged on the inner side of the snap ring 2 in the circumferential direction (it can be understood that the plurality of fixing grooves 12 are arranged on the two semicircular structures respectively), and a moving assembly is arranged in the fixing groove 12; the moving assembly includes a spring 11 and a pulley 9, the bottom of the pulley 9 is in contact with the outer wall of the pipeline 1, one end of the spring 11 is connected with the pulley 9, and the other end is in contact with the fixing groove 12.

[0050] When it is necessary to adjust the installation position of the device, the bolts on both sides can be slightly loosened, so that the two semicircular structures are away from each other and there is a gap with the outer wall of the pipeline 1. At this time, the spring 11 is stretched so that the pulley 9 is always in contact with the outer wall of the pipeline 1 (in this process, the spring 11 is always in a compressed state), and the worker can pull the device to move on the pipeline 1 to move it to the appropriate position. When moved to the appropriate position, tighten the bolts, and at this time the pulley 9 moves back to the inside of the fixing groove 12 under pressure.

[0051] In the embodiment, the number of pulleys 9 is four. It can be understood that the number of pulleys 9 can be more. For example, the number of pulleys 9 can be selected according to the spring force of the spring 11, so that when the bolts are loosened, the two semicircular structures can have a gap with the outer wall of the pipeline 1.

[0052] The above scheme can facilitate the movement of the device, and at the same time can avoid the friction loss caused by the contact between the snap ring 2 and the outer wall of the pipeline 1 during movement.

[0053] Continue to refer to Figure 3 , the moving assembly further includes a fixed plate 10; the pulley 9 is installed below the fixed plate 10, and the spring 11 connects the pulley 9 through the fixed plate 10. The fixed plate 10 can provide a sufficient contact surface for the spring 11, thereby helping to better transmit the spring force of the spring 11 to the pulley 9.

[0054] Continue to refer to Figure 3The top of the fixed plate 10 is provided with an extension rod 3, and the top of the fixed groove 12 is provided with a through hole; the extension rod 3 passes through the through hole and is connected with a limiting plate 4; a spring 11 is sleeved on the extension rod 3; the inner diameter of the spring 11 is greater than or equal to the hole diameter of the through hole. The extension rod can guide the movement of the spring 11 and the pulley 9, so that the pulley 9 is prevented from deviating and affecting the movement of the device on the pipeline 1. In addition, the extension rod can be used by the user to adjust the angle of the pulley 9, so that the pulley 9 is prevented from tilting and affecting the movement effect.

[0055] In the description of the present application, it should be understood that the orientation words such as "front", "back", "up", "down", "left", "right", "transverse", "vertical", "vertical", "horizontal" and "top", "bottom" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and in the absence of the opposite description, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner" and "outer" refer to the inner and outer of the contour of each component itself.

[0056] In order to facilitate the description, the area relative terms such as "on", "above", "upper surface", "upper" and the like can be used here to describe the area position relationship of one or more components or features shown in the figure with other components or features. It should be understood that the area relative terms not only include the orientation of the components described in the figure, but also include different orientations in use or operation. For example, if the components in the figure are inverted as a whole, the components "above" or "above" other components or features will include the case of "below" or "below" other components or structures. Therefore, the example term "above" can include both "above" and "below". In addition, these components or features can also be positioned at other different angles (for example, rotated by 90 degrees or other angles), and all these cases are intended to be included herein.
