Description

Technical Field

[0001] The invention relates to the technical field of alternating electromagnetic processing devices, in particular to an alternating electromagnetic processing device applied to a cooling circulating water system. Background Art

[0002] With the continuous growth of global energy demand and the increasing attention to environmental protection, waste heat power generation, as an efficient energy recovery and utilization technology, has been widely used in many industrial fields. Waste heat power generation can convert waste heat and residual heat generated in the industrial production process into electrical energy, which not only improves energy utilization efficiency, reduces energy waste, but also reduces the production cost of enterprises. At the same time, it is of great significance to alleviate energy shortages and reduce environmental pollution.

[0003] According to a publicly disclosed alternating high-frequency electromagnetic field water treatment device (publication number: CN221500730U), in the above application, a buffer component is set so that during the water intake process, the water will impact the lower baffle plate, causing the lower baffle plate to move to the right, thereby turning the swivel. During the rotation of the swivel, the flow rate will be initially reduced, and at the same time, the flow rate will be further reduced under the action of the damping ring. After the flow rate is reduced, the water will slowly move to the right and enter the interior of the treatment tube. At this time, the water can be efficiently treated by energizing the coil. However, when the existing alternating electromagnetic treatment device for the cooling circulating water system of waste heat power generation is used, although the alternating electromagnetic treatment device can theoretically change the crystallization state of calcium, magnesium and other ions in the water to prevent scale formation.

[0004] However, in actual operation, changes in the circulating water temperature will affect its anti-scaling and descaling effects. For example, when the cooling circulating water temperature rises, the activity of ions in the water may increase, causing the alternating electromagnetic device to have a less stable inhibitory effect on scale than at low temperatures, and local scaling may still occur.

DETAILED DESCRIPTION

[0018] like Figure 1-Figure 5 As shown, the present invention provides an alternating electromagnetic treatment device applied to a cooling circulating water system.

[0019] like Figure 1 As shown, the cooling circulating water system 12 includes a circulating pipe 13 through which the cooling circulating water flows, and the alternating electromagnetic treatment device (including the alternating electromagnetic treatment machine 2 ) is arranged on the circulating pipe 13 .

[0020] like Figure 2 As shown, the alternating electromagnetic treatment device comprises a base 1 , on which an alternating electromagnetic treatment machine 2 is fixedly mounted, and an electromagnetic coil 11 of the alternating electromagnetic treatment machine 2 is wound around the outer surface of a circulation pipe 13 .

[0021] Specifically in this embodiment, a control box 5 and a high-frequency alternating signal generator 10 are fixedly mounted on the top of the base 1 .

[0022] The working principle of water treatment of the alternating electromagnetic treatment device is as follows: the electromagnetic coil 11 of the alternating electromagnetic treatment machine 2 generates a high-frequency alternating electromagnetic field on the circulation pipe 13, so that the water passing through the circulation pipe 13 is magnetized by the alternating electromagnetic field; 1) Anti-scaling: After magnetization, some hydrogen bonds of water molecules are destroyed, and the hydrated ions are subjected to the Lorentz force to perform spiral circular motion, the large molecular clusters are sheared and reduced, and the freed water molecules occupy the various gaps in the water body, thereby inhibiting the formation of crystals on the inner wall of the pipe; 2) Descaling: Under the action of the magnetic field, the solubility of water molecules is increased, the viscosity is reduced, and the permeability is enhanced, which makes it easier for water molecules to penetrate Penetrating into the tiny gaps of scale, the magnetized water changes and destroys the lattice structure of hard salt, so that the old scale is soaked, broken, peeled off and falls off from the joints of the wall; 3) Energy saving and emission reduction: After using water treatment equipment equipped with an alternating electromagnetic treatment device, there is no need to add scale inhibitors and corrosion inhibitors, which can improve production efficiency by 5%-30%, save more than 75% of drainage, reduce production costs, reduce environmental pressure, and help enterprises achieve zero emissions; 4) Sterilization and algae removal: The alternating electromagnetic field water treatment device can kill about 90% of bacteria and algae spores, and the effective killing rate for some common bacteria can be as high as 99.99%.

[0023] In specific practice, in different application scenarios and different water quality conditions, the operator can adjust the parameters of the high-frequency alternating signal generator 10 to ensure that the generated electromagnetic field can achieve better descaling, anti-scaling and sterilization and algae removal effects.

[0024] However, in actual operation, changes in the circulating water temperature will affect the anti-scaling and descaling effects. When the cooling circulating water temperature rises (above 32 degrees Celsius), the activity of ions in the water will increase, causing the alternating electromagnetic device to have a less stable inhibitory effect on scale than at low temperatures, and local scaling may still occur.

[0025] like Figure 2-Figure 5 As shown, a rotating assembly 6 is arranged inside the circulation pipe 3 where the electromagnetic coil 11 is located; The rotating assembly 6 includes: a fixed shaft 61, which is arranged at the central axis position of the circulation pipeline 13; a propeller blade 62 is rotatably mounted on the fixed shaft 61, and at least one ionization filter component 63 is fixedly mounted on the fixed shaft 61; The ionization filter component 63 includes a first electrode 64, a second electrode (not shown in the figure) and a filter membrane. The first electrode 64 and the filter membrane are integrally formed and made of hydroxylated multi-walled carbon nanotubes. The second electrode is a graphite electrode. A temperature detector 14 is installed inside the circulation pipe 3 at the location of the electromagnetic coil 11; when the temperature detector 14 detects that the water temperature in the circulation pipe 3 reaches 32 degrees Celsius or above, the power supply of the ionization filter component 63 is connected. When the temperature detector 14 detects that the water temperature in the circulation pipe 3 is lower than 32 degrees Celsius, the power supply of the ionization filter component 63 is disconnected.

[0026] In the above structure, when the circulating water in the circulation pipe 3 flows through the propeller blade 62, the flow of water drives the rotation of the propeller blade 62. The ionization filter component 63 does not work under normal circumstances. When the temperature detector 14 detects that the temperature in the circulation pipe 3 reaches 32 degrees Celsius or above, the controller in the control box 5 starts the power supply of the ionization filter component 63, applies a voltage between the first electrode 64 and the second electrode, and the ionization filter component 63 starts to work, and performs ionization filtration treatment on the circulating water passing through the hydroxylated multi-walled carbon nanotubes.

[0027] More preferably, in this embodiment, an ionization filter component 63 is installed between every two adjacent propeller blades 62 , and the rotating assembly 6 includes four ionization filter components 63 .

[0028] like Figure 2-Figure 5 As shown, a bypass water injection assembly 8 is fixedly arranged inside the base 1; the bypass water injection assembly includes a water storage tank 83, a buffer water tank 811 and a connection box 84; The water storage tank 83 is in fluid communication with the buffer water tank 811 via the first connecting pipe 814; the buffer water tank 811 is in fluid communication with the first pipe opening of the second connecting pipe 812; A switch mechanism for opening or closing the second pipe opening is provided at the second pipe opening of the second connecting pipe 812; when the temperature detector 14 detects that the temperature in the circulation pipe 3 reaches above 32 degrees Celsius, the switch mechanism is in an open state, and the second pipe opening of the second connecting pipe 812 is liquid-connected with the connection box 84; when the temperature detector 14 detects that the temperature in the circulation pipe 3 is lower than 32 degrees Celsius, the switch mechanism is in a closed state, and the second pipe opening of the second connecting pipe 812 is closed.

[0029] In the above structure, the inventors use a combination of an ionization filter component 63 and a bypass water injection assembly 8 to solve the technical problem of poor anti-scaling effect caused by an increase in the temperature of the cooling circulating water.

[0030] When the temperature of the cooling circulating water rises (above 32 degrees Celsius), the activity of ions in the water will increase, resulting in the alternating electromagnetic device not being as stable as at low temperatures in inhibiting scale, and local scaling may still occur. The inventor tried to add an ionization filter component 63, and after screening, selected hydroxylated multi-walled carbon nanotubes (hydroxylated multi-walled carbon nanotubes with a first electrode and a filter membrane integrated) to perform ionization filtration on the circulating water, and fixedly set it between adjacent propeller blades 62, and the propeller blades 62 drive the rotation of the hydroxylated multi-walled carbon nanotubes, thereby improving the ionization filtration effect.

[0031] Preferably, the power supply of the ionization filter component 63 is an alternating power supply. Regarding the parameters of the ionization filter component 63, the inventor of the present application has optimized and screened. When the alternating frequency is 25-35 Hz and the electric field strength between the first electrode 64 and the second electrode is 500-1000 V / m, a better ionization filtering effect can be achieved.

[0032] However, in actual practice, the inventors found that after the cooling circulating water in the circulation pipe 13 is magnetized by the alternating electromagnetic field, a small amount of flocculent precipitation will be produced (when there are too many floccules, scale will be formed). The presence of these flocculent precipitations will affect the work of the hydroxylated multi-walled carbon nanotubes.

[0033] Therefore, the inventor tried to make further improvements on the basis of adding the structure of the rotating assembly 6, and unexpectedly found that this problem can be improved by adding a bypass water injection assembly 8. When the water temperature is higher than 32 degrees Celsius, the second nozzle of the second connecting pipe 812 is opened by the switch mechanism, and the water in the water storage tank 83 is appropriately injected into the circulation pipe 13. The water storage tank 83 is arranged in the base 1, close to the circulation pipe 13, and the water temperature in the water storage tank 83 will be affected by the water temperature in the circulation pipe 13; generally speaking, the water temperature in the water storage tank 83 rises slightly behind the water temperature in the circulation pipe 13, so the water temperature in the water storage tank 83 is slightly lower than the water temperature in the circulation pipe 13. The inventor found that by adding a bypass water injection assembly 8 and appropriately injecting water in the water storage tank 83, the effect of flocculent precipitation on hydroxylated multi-walled carbon nanotubes can be significantly improved / mitigated, so that the ionization filter component 63 can play its role, thereby alleviating the problem of enhanced ion activity of circulating water at high temperature, and finally solving the technical problem of poor anti-scaling effect caused by increased temperature of cooling circulating water.

[0034] Regarding the implementation of the above-mentioned switch mechanism, preferably, in this embodiment, the switch mechanism includes a connecting block 87, a hollow conduit 88, a fixing spring 810, a fixing disk 89, a cam 86 and a micro-motor shaft 85; The upper end of the connecting block 87 is located inside the connecting box 84 and the lower end thereof passes through the bottom of the connecting box 84; the upper end of the conduit 88 is located inside the connecting box 84 and the lower end thereof passes through the bottom of the connecting box and the connecting block 87 in sequence; the conduit 88 is slidably connected to the connecting box 84 and the connecting block 87; the bottom of the conduit 88 is fixedly connected to the fixing plate 89, and the fixing spring is sleeved on the outer wall of the conduit 88 and is elastically abutted between the bottom outer wall of the connecting box 84 and the upper surface of the fixing plate 89; the lower surface of the fixing plate 89 abuts against the cam 86, and the cam 86 is fixedly arranged on the micromotor shaft 85; A through hole 880 is provided in the tube wall of the conduit 88; when the switch mechanism is in an open state, the raised end of the cam 86 abuts against the lower surface of the fixed disk 89, and the second tube opening of the second connecting tube 812 is connected to the through hole 880; when the switch mechanism is in a closed state, the base circular end of the cam 86 abuts against the lower surface of the fixed disk 89, and the second tube opening of the second connecting tube 812 is closed by the outer wall of the conduit 88.

[0035] In this embodiment, if Figure 3 and Figure 4 As shown, the through hole 880 of the conduit 88 and the second pipe opening of the second connecting pipe 812 are located below the connecting box 84 .

[0036] In this embodiment, a water pump 813 is installed on the first connecting pipe 814. In this embodiment, the water pump 813 is a peristaltic pump.

[0037] Preferably, in this embodiment, a bypass filter pipeline 15 is arranged downstream of the cooling water circulation system 12 and near the cooling tower, and a filter plate 16 is fixedly installed on one side of the bypass filter pipeline 15 close to the cooling tower; preferably, an aragonite filter 17 is installed on the other side of the bypass filter pipeline 15.

[0038] Generally speaking, the alternating electromagnetic treatment machine 2 is arranged at an upstream position of the cooling water circulation system 12, that is, the water in the upstream circulation pipe 13 is magnetized under the action of the alternating electromagnetic field, but when the circulating water flows to the downstream position, the magnetization effect weakens, and flocculent precipitation may be generated. Therefore, the inventors set a bypass filter pipeline 15 downstream of the cooling water circulation system 12 and near the cooling tower, and in particular, use a filter disc 16 and an aragonite filter 17 to filter and treat the flocculent precipitation in the circulation pipe 13, so as to further alleviate the adverse effects of flocculent precipitation.

[0039] After knowing the alternating electromagnetic treatment device of the present invention, those skilled in the art can apply it to a cooling circulating water system, especially a cooling circulating water system for waste heat power generation.

[0040] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
