DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, the defluorination device 10 with a spray structure provided by the embodiment of the utility model includes, for example, a reaction tower 101, a spray structure 100 and a circulation structure. There are multiple spray structures 100, each of which includes, for example, a spray body 110, a driving assembly 120, a spray head 140 and a moving part 150.

[0024] Specifically, the reaction tower 101 is provided with a first feed port 1011, the injection structure 100 is provided in the reaction tower 101, the injection body 110 has an inner cavity 111, and the injection body 110 is provided with a second feed port 160 connected to the inner cavity 111. The driving assembly 120 is provided in the inner cavity 111. The nozzle 140 is provided at the bottom of the injection body 110, and the nozzle 140 is provided with an injection port 141. The moving member 150 is connected to the driving assembly 120, and one end of the moving member 150 is movably connected to the injection port 141. The circulation structure is connected to the second feed port 160.

[0025] Among them, the reaction tower 101 is used to pass fluorine-containing waste gas and add a defluorinating agent to the reaction tower 101 to defluorinate the fluorine-containing waste gas, and exhaust the gas with a fluorine content that meets the standard from the exhaust port. The injection body 110 is the shell or frame of the injection structure 100. The injection body 110 has an inner cavity for storing liquid defluorinating agent, and the second feed port 160 is used to add or supplement the liquid defluorinating agent to the inner cavity 111. A nozzle 140 is provided at the bottom of the injection body 110, and a nozzle 141 is provided on the nozzle 140. In one embodiment of the present embodiment, the nozzle 140 is an atomizing nozzle structure. The atomizing nozzle structure is used to disperse the liquid (for example, a defluorinating agent) into fine droplets to form a mist, which can increase the surface area of ​​the liquid in contact with the air, thereby enhancing the efficiency of the chemical reaction. In another embodiment of the present embodiment, the nozzle 140 is a fan-shaped nozzle. The fan-shaped nozzle can produce fan-shaped sprays at various angles, which helps to achieve a wider coverage range and improve the uniformity of the spray. The driving assembly 120 includes, for example, a motor, a cylinder or other forms of driving mechanisms. The moving member 150 is, for example, made of plastic, and the moving member 150 is, for example, set to be needle-shaped, and of course, it can also be other shapes, which are not specifically limited here. The end of the moving member 150 close to the injection port 141 matches the shape and size of the injection port 141. The circulation structure is used to collect the liquid in the inner cavity 111 and circulate it back to the inner cavity 111 for reuse, wherein the liquid includes unreacted liquid defluorinating agent and liquid generated by the defluorination reaction between the defluorinating agent and the fluorine-containing waste gas in the inner cavity 111.

[0026] The injection structure 100 has, for example, a first state and a second state. In the first state, one end of the moving member 150 close to the injection port 141 is connected to the injection port 141, and in the second state, a gap is formed between the moving member 150 and the injection port 141. In the first state, one end of the moving member 150 close to the injection port 141 is in contact with the injection port 141, so that the liquid in the inner cavity 111 cannot be ejected from the injection port 141. In the second state, the moving member 150 is driven by the driving assembly 120 to move the moving member 150 upward relative to the injection port 141, and a gap is formed between one end of the moving member 150 close to the injection port 141 and the injection port 141. This gap allows the liquid in the inner cavity 111 to be ejected through the injection port 141 to form the desired spray or jet. In the second state, the injection structure 100 sprays a liquid defluorinating agent to contact the exhaust gas for a chemical reaction to remove fluorine from the exhaust gas.

[0027] The embodiment of the utility model is provided with a spray structure 100, the spray structure 100 includes a spray body 110, a driving assembly 120, a nozzle 140 and a moving part 150, the spray body 110 has an inner cavity 111, and the inner cavity 111 is used to contain a liquid defluorinating agent. The moving part 150 is connected to the driving assembly 120, and the spray structure 100 includes a first state and a second state. In the first state, one end of the moving part 150 close to the injection port 141 is in contact with the injection port 141, and in the second state, the moving part 150 is driven by the driving assembly 120 to move the moving part 150 upward relative to the injection port 141, and a gap is formed between one end of the moving part 150 close to the injection port 141 and the injection port 141, and this gap allows the liquid in the inner cavity 111 to be ejected through the injection port 141 to form a desired spray or jet flow. By controlling the conversion from the first state to the second state, the operator can accurately control the start and end of the spray according to actual needs, thereby accurately controlling the amount of defluorinating agent used, which helps to reduce the waste of defluorinating agent. At the same time, the design of the circulation structure further improves the efficiency of the defluorination agent, reduces resource waste and reduces costs.

[0028] Specifically, the defluorination device 10 with the injection structure also includes, for example, a connecting pipe. Multiple injection structures 100 are connected through the connecting pipe. In some embodiments, the number of connecting pipes is, for example, multiple, and two adjacent injection structures 100 are connected through one connecting pipe. When treating a large amount or a large volume of fluorine-containing waste gas, multiple injection structures 100 can provide a wider coverage to ensure that the waste gas is fully defluorinated.

[0029] Specifically, the driving assembly 120 includes, for example, a first magnet 121, an elastic member 122, and a second magnet 123. The first magnet 121 is, for example, disposed in the inner cavity 111. The first magnet 121 is, for example, an electromagnet, which is usually composed of a coil and an iron core, and the presence or absence of magnetic force can be controlled by turning the current on and off. The elastic member 122 is, for example, disposed in the inner cavity 111. The elastic member 122 is, for example, a spring, and one end of the elastic member 122 is, for example, connected to the first magnet 121. The second magnet 123 is, for example, disposed in the inner cavity 111. The second magnet 123 is connected to the other end of the elastic member 122. The second magnet 123 is, for example, an armature, and the armature is usually attracted when the first magnet 121 generates a magnetic field. The moving member 150 is connected to the side of the second magnet 123 away from the first magnet 121. And the magnetic force of the first magnet 121 can be quickly established and disconnected by whether it is powered on, so that the injection structure 100 can respond quickly and improve the operating efficiency.

[0030] In the second state, the first magnet 121 is energized, and the second magnet 123 is attracted by the first magnet 121 and moves upward through the magnetic force control of the first magnet 121, thereby driving the moving member 150 to move upward relative to the injection port 141, and compressing the elastic member 122, so that a gap is formed between the end of the moving member 150 close to the injection port 141 and the injection port 141 to allow the liquid in the inner cavity 111 to be ejected through the injection port 141, and the injection structure 100 sprays the liquid defluorinating agent to contact the waste gas for chemical reaction to remove the fluorine in the waste gas. When the second state is switched to the first state, the first magnet 121 is stopped from being energized, and the elastic member 122 pushes the second magnet 123 to move downward, driving the moving member 150 to move downward so that the end of the moving member 150 close to the injection port 141 fits with the injection port 141, and at this time, the liquid in the inner cavity 111 cannot be ejected through the injection port 141.

[0031] Specifically, the defluorination device 10 with the injection structure, for example, further includes a control switch 130. The control switch 130 is, for example, electrically connected to the drive assembly 120, and the control switch 130 is used to switch the injection structure 100 from the first state to the second state or to switch the injection structure 100 from the second state to the first state. The control switch 130 is, for example, an electrical switch, which is used to control whether the first magnet 121 is powered. The control switch 130 can be a manual switch, a timing switch, a remote control switch, etc., which can be set according to actual needs and is not limited here.

[0032] Specifically, the reaction tower 101 is provided with a circulating infusion port 1012, for example, and the circulating structure includes a reflux pipe 320 and a circulating pump 330. The defluorination device 10 with an injection structure also includes a feeding pipe 310, for example, and the feeding pipe 310 is connected between the first feeding port 1011 and the reflux pipe 320, and the feeding pipe 310 is connected to the second feeding port 160. Specifically, the feeding pipe 310 and the reflux pipe 320 are provided with valves, for example, respectively, so that the operator can quickly start or stop the feeding or reflux as needed, thereby improving the flexibility of operation. The liquid sprayed by the nozzle 140 drips into the bottom of the reaction tower 101. The reaction tower 101 is provided with a circulating infusion port 1012, and the reflux pipe 320 is connected between the first feeding port 1011 and the circulating infusion port 1012. The circulation pump 330 is, for example, arranged on the reflux pipe 320. The circulation pump 330 is, for example, a centrifugal pump or other types of pumps. The selection depends on the properties of the liquid defluorinating agent and the specific requirements of the circulation structure, which are not limited here. The circulation pump 330 is used to drive the liquid to flow in the reflux pipe 320. The unreacted liquid defluorinating agent sprayed by the nozzle 140 collected by the reaction tower 101, and the zirconium fluoride solid and fluoride salt solution produced by the defluorination reaction between the liquid defluorinating agent and the fluorine-containing waste gas in the reaction tower are driven by the circulation pump 330 to be transported from the circulation infusion port 1012 through the reflux pipe 320 to the first feeding port 1011, and then transported to the inner cavity 111 through the connected second feeding port 160 for reuse. In addition, a drain pipe and a corresponding valve can be opened on the reflux pipe 320. When the defluorinating agent is circulated for the maximum effective number of cycles, the valve can be opened to allow the recycled defluorinating agent to flow out from the infusion pipe and be collected for use.

[0033] Specifically, the defluorination device 10 with the injection structure further includes, for example, a power supply structure 200 . The power supply structure 200 includes, for example, a battery. The power supply structure 200 is electrically connected to the first magnet 121 to supply power to the first magnet 121 .

[0034] Furthermore, the defluorination device 10 with the injection structure further includes a protection structure 400, which is electrically connected to the power supply structure 200. The protection structure 400 is, for example, an overload protection structure or a short circuit protection structure, which prevents the drive assembly 120 from being damaged due to long-term operation or excessive load, thereby improving the safety of the device.
