[0036] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0037] The water mist guide system and fire suppression equipment according to the present invention will be described below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, in an embodiment of the present invention, a water mist guiding system is proposed, which includes: a charging module and an acceleration guiding module. The charging module is used to connect to the mist outlet of the atomizer and charge the water mist discharged from the mist outlet; the acceleration guiding module includes a first electrode plate 10 and a second electrode plate 11 with opposite electrode polarities and capable of generating an accelerating electric field force. The charging module is located between the first electrode plate 10 and the second electrode plate 11. The electrode polarity of the first electrode plate 10 is the same as the electrode polarity of the charged water mist. The first electrode plate 10 is used to correspond to the mist outlet setting, and the second electrode plate 11 is used to correspond to the protected area setting. The first electrode plate 10 and the second electrode plate 11 are used to accelerate the migration of the charged water mist through the accelerating electric field force.

[0039] The water mist guidance system of the present invention comprises a charging module and an accelerating guidance module. The accelerating guidance module comprises a first electrode plate 10 and a second electrode plate 11 of opposite electrical polarity. The charging module is disposed between the first electrode plate 10 and the second electrode plate 11. The charging module generates an induced electric field. As the water mist passes through the induced electric field and, under the action of the induced electric field force, a large number of charge carriers accumulate on the surface of the water mist droplets, causing the water mist to be converted into charged water mist and assume electrical properties. Accelerated by the accelerating electric field force, the charged water mist quickly reaches the protected area. The first electrode plate 10 is disposed corresponding to the mist outlet, and the second electrode plate 11 is disposed corresponding to the protected area. The electrode polarity of the first electrode plate 10 is the same as that of the charged water mist. Because the charged water mist carries the same charge and there is a repulsive force between the charges, the charged water mist is less likely to aggregate. An accelerating electric field is formed between the first electrode plate 10 and the second electrode plate 11. Accelerated by the accelerating electric field force, the charged water mist is directed and quickly reaches the protected area. The water mist guide system of the present invention converts the sprayed water mist into charged water mist by arranging a charging module at the mist outlet of the atomizer, and accelerates the migration of the charged water mist through the accelerating electric field between the first electrode plate 10 and the second electrode plate 11. Under the influence of the acceleration of the accelerating electric field force, the charged water mist can quickly and accurately cover the area to be protected, effectively and accurately prevent fire and explosion, and improve the fire extinguishing efficiency.

[0040] like Figure 1As shown, in an embodiment of the present invention, the charging module includes a mist outlet pipe 20 and a charging assembly. The mist outlet pipe 20 is an insulating component and is used to connect to the mist outlet. The charging assembly includes a charging power supply 23 and a charging sleeve 21 and a charging ring 22 respectively arranged at both ends of the mist outlet pipe 20. The charging sleeve 21 and the charging ring 22 are both conductive parts. One of the charging sleeve 21 and the charging ring 22 is grounded, and the other is connected to the positive pole of the charging power supply 23. The negative pole of the charging power supply 23 is grounded, and a charging channel is formed between the charging sleeve 21 and the charging ring 22 for the charged water mist to pass through.

[0041] like Figure 1 As shown, in one embodiment of the present invention, the positive pole of the charging power source 23 is electrically connected to the charging sleeve 21, the negative pole of the charging power source 23 is grounded, and the charging ring 22 is grounded. Under the action of the induced electric field force, a large number of positively charged carriers will gather on the surface of the water mist droplets, and the carriers of opposite charge will flow away through the grounded negative pole of the charging power source 23. At this time, the charging sleeve 21 is positively charged, and the water mist is converted into charged water mist carrying positively charged carriers after passing through the induced electric field generated between the charging sleeve 21 and the charging ring 22. The charged water mist is discharged from the bottom of the charging channel and quickly reaches the protected area under the action of the accelerating electric field. Among them, explosive combustion involves a chain chemical reaction, and the positively charged charged water mist can neutralize the free radicals generated by the chain reaction, further weakening the efficiency of the chemical reaction and reducing the risk of explosive combustion.

[0042] like Figure 2 As shown, in another embodiment of the present invention, the positive pole of the charging power source 23 and the charging ring 22 are electrically connected, the negative pole of the charging power source 23 is grounded, and the charging sleeve 21 is grounded. Under the action of the induced electric field force, a large number of negatively charged carriers will gather on the surface of the water mist droplets, and the carriers of opposite charges will flow away through the negative ground of the charging power source 23. At this time, the charging sleeve 21 is negatively charged, and the charged water mist is converted into charged water mist carrying negatively charged carriers after passing through the induced electric field generated between the charging sleeve 21 and the charging ring 22. The charged water mist is discharged from the bottom of the charging channel and quickly reaches the protected area under the action of the accelerating electric field. For open flames, the negatively charged charged water mist can neutralize static electricity, and the charged water mist can effectively and quickly extinguish open flames.

[0043] like Figure 1As shown, in an embodiment of the present invention, the mist outlet pipe 20 includes a docking portion 201 and a flared portion 202. One end of the docking portion 201 is docked with the atomizer, and the charging sleeve 21 is sleeved outside the docking portion 201. The flared portion 202 is docked with the other end of the docking portion 201, and the charging ring 22 is arranged at the end of the flared portion 202 away from the docking portion 201 to ensure that the induced electric field has enough space to fully convert the water mist into charged water mist. The charged water mist is transported from the docking portion 201 to the flared portion 202, and is output to the outside world from the opening of the flared portion 202 away from the docking portion 201. Among them, the cross-sectional size of the flared portion 202 is gradually expanded from the docking portion 201 to the flared portion 202, which is conducive to improving the transportation efficiency of the charged water mist.

[0044] like Figure 1 As shown, the vertical direction is the up-down direction in the figure. In an embodiment of the present invention, the first electrode plate 10 and the second electrode plate 11 are spaced apart in the vertical direction, with the first electrode plate 10 positioned above the second electrode plate 11. The charging sleeve 21 is mounted on the upper end of the mist outlet pipe 20, and the charging ring 22 is connected to the lower end of the mist outlet pipe 20. The outer surface of the charging sleeve 21 is covered with an insulating layer. The arrangement direction of the mist outlet pipe 20 is consistent with the direction of gravity acting on the charged water mist, which facilitates the charged water mist to reach the protected area more quickly.

[0045] It should be noted that the first electrode plate 10 and the second electrode plate 11 are connected in sequence to the positive and negative poles of the same regulated power supply 12. The setting of the positive and negative poles of the regulated power supply 12 is adjusted according to the positive and negative electrical properties of the carriers carried by the charged water mist to ensure that the electrode polarity of the first electrode plate 10 and the electrode polarity of the charged water mist are the same and there is a repulsive force, ensuring that the charged water mist is transported to the protected area through the charging channel.

[0046] like Figure 3 As shown, in an embodiment of the present invention, the water mist guidance system further includes a water mist accelerator 30. The water mist accelerator 30 is located between the charging module and the second electrode plate 11 and is used to accelerate the charged water mist toward the second electrode plate 11. This can guide the charged water mist and further shorten the time it takes for the charged water mist to reach the protected area. The charging module and the second electrode plate 11 are both spaced apart from the water mist accelerator 30.

[0047] like Figure 3 As shown, in an embodiment of the present invention, there are multiple water mist accelerators 30, and the multiple water mist accelerators 30 are arranged at intervals along the charged water mist acceleration direction, and the electrode polarities of any two adjacent water mist accelerators 30 are opposite, which can improve the efficiency of transporting charged water mist.

[0048] In an embodiment of the present invention, the water mist accelerator 30 is provided with a hollow acceleration channel for the charged water mist to pass through, so that the charged water mist can be conveniently transported to the protected area through the hollow acceleration channel. The water mist accelerator 30 is configured in a cylindrical or sheet-like structure that can guide and accelerate the charged water mist, thereby serving the purpose of guiding the charged water mist.

[0049] like Figure 3 As shown, in the embodiment of the present invention, multiple water mist accelerators 30 are each cylindrical, with the length of the hollow acceleration channel gradually increasing along the direction of the charged water mist acceleration. This provides sufficient displacement distance for the accelerated charged water mist, ensuring that the charged water mist is better accelerated as it passes through the hollow acceleration channel. The hollow acceleration channel of the water mist accelerator 30 located near the charged ring 22 is the shortest.

[0050] like Figure 3 As shown, in an embodiment of the present invention, the water mist guide system further includes an acceleration power supply 40. The multiple water mist accelerators 30 are electrically connected to the acceleration power supply 40, ensuring that the charged water mist can quickly reach the protected area under the acceleration of the induced electric field. The acceleration power supply 40 is an AC power supply.

[0051] In an embodiment of the present invention, a fire and explosion suppression device is also provided, comprising an atomizer and the water mist guide system described above. Since the fire and explosion suppression device utilizes all embodiments of the water mist guide system, it also possesses all the beneficial effects provided by the water mist guide system and will not be described in detail here.
