Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chlorine recovery and treatment, and specifically to a spray device for chlorine recovery. Background Technology
[0002] Chlorine is a yellow-green, highly toxic gas with a strong, pungent odor at room temperature and pressure. It is suffocating, denser than air, soluble in water and alkaline solutions, readily soluble in organic solvents, easily compressible, and can be liquefied into a yellow-green, oily liquid chlorine. It is one of the main products of the chlor-alkali industry and can be used as a strong oxidizing agent.
[0003] In the electrolytic treatment of acidic copper chloride etching solution, chlorine gas is released in the cathode area of the electrolytic cell, which pollutes the air and wastes resources. Therefore, the chlorine gas needs to be treated. The conventional method for treating chlorine gas is to pass the chlorine gas into liquid alkali to form sodium hypochlorite for absorption.
[0004] However, if the flow rate of chlorine gas is too fast during the process of introducing chlorine gas into liquid alkali, the reaction rate may not be able to keep up with the supply rate of chlorine gas. This can lead to unreacted chlorine gas accumulating in the reaction system and eventually overflowing, causing chlorine gas leakage and polluting the environment. Utility Model Content
[0005] The purpose of this invention is to provide a spray device for chlorine recovery to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides a spraying device for chlorine recovery, comprising an absorption tank and a spraying assembly. The absorption tank is filled with a reaction liquid, and an air inlet is located at the bottom of the absorption tank through which chlorine gas is introduced. The top of the absorption tank is open, and an installation position is provided at the open position. The spraying assembly includes a support frame and a spray pipe. The spray pipe is fixed to the support frame, which is ring-shaped. A rotating bearing is provided at the installation position. The spray pipe is located within the inner ring of the support frame, and the support frame is mounted on the rotating bearing. A high-pressure nozzle is provided on the side of the spray pipe facing the absorption tank, and an injection port is provided on the side of the spray pipe away from the absorption tank.
[0007] Furthermore, the spray pipe includes a first pipe and a second pipe, which intersect at an angle, and both the first pipe and the second pipe are equipped with the high-pressure nozzle.
[0008] Furthermore, the injection port is provided at the intersection of the first pipe and the second pipe, the injection port is connected to the high-pressure nozzle, and the injection port is provided with an adapter, which is rotatably connected to the injection port.
[0009] Furthermore, the spray pipe is also equipped with a drive nozzle, which faces the side wall of the absorption tank in an open position towards the top.
[0010] Furthermore, the support frame includes a top surface and a bottom surface, both the first pipe and the second pipe are installed on the bottom surface of the support frame, and the drive nozzle is located on one side of the first pipe or the second pipe.
[0011] Furthermore, the driving nozzle is a booster head, and the extension direction of the driving nozzle is set at an angle to the direction of the first pipe or the direction of the second pipe.
[0012] Furthermore, the intersection of the first pipe and the second pipe is the center of the support frame.
[0013] Furthermore, there are two drive nozzles, both of which are installed on the first pipe or the second pipe, and the two drive nozzles are arranged in a centrally symmetrical manner.
[0014] Furthermore, the air intake port is equipped with a one-way valve.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. Before using the spray device, first install the support frame onto the rotating bearing, ensuring that the spray pipe on the support frame faces downwards and the injection port faces upwards. Then, inject some reaction liquid into the absorption tank, connecting the injection port to the injection pipe. After the spray device is used, chlorine gas is introduced into the absorption tank through the gas inlet and reacts with the reaction liquid inside. Once the high-pressure nozzle on the spray pipe is activated, it can spray the reaction liquid in a mist form, effectively absorbing any overflowing chlorine gas and preventing chlorine leakage.
[0017] 2. An injection port is located at the intersection of the first and second pipes. The injection port is connected to the high-pressure nozzle and is equipped with an adapter that is rotatably connected to the injection port. Since the rotation of the support frame drives the spray pipe to rotate, a rotatable adapter is provided. When the injection pipe is connected, the injection pipe will not get tangled even if the support frame rotates.
[0018] 3. The spray pipe is also equipped with a drive nozzle. The drive nozzle faces the open side wall of the top of the absorption tank. The drive nozzle is a booster head. After the liquid sprayed by the drive nozzle hits the open side wall, it will generate a recoil force, which can drive the support frame to rotate and drive the spray pipe to rotate, so as to realize rotating spraying, making the spraying area larger and more conducive to absorbing the overflowing chlorine gas.

[0028] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0029] Reference Figures 1 to 3 This utility model provides a spraying device for chlorine recovery, comprising an absorption tank 1 and a spraying assembly 2. The absorption tank 1 is filled with a reaction liquid. An air inlet 11 is located at the bottom of the absorption tank 1, through which chlorine gas is introduced. The top of the absorption tank 1 is open 12, and a mounting position is provided at the open 12. The spraying assembly 2 includes a support frame 21 and a spray pipe 22. The spray pipe 22 is fixed to the support frame 21, which is ring-shaped. A rotating bearing 13 is provided at the mounting position. The spray pipe 22 is located within the inner ring of the support frame 21, and the support frame 21 is mounted on the rotating bearing 13. A high-pressure nozzle 221 is provided on the side of the spray pipe 22 facing the absorption tank 1, and an injection port 222 is provided on the side of the spray pipe 22 away from the absorption tank 1. A support leg 14 is provided at the bottom of the absorption tank 1 to support it.
[0030] Before using the spraying device, first install the support frame 21 onto the rotating bearing 13, ensuring that the spray pipe 22 on the support frame 21 faces downwards and the injection port 222 faces upwards. Then, inject a portion of the reaction liquid into the absorption tank 1, connecting the injection port 222 to the injection pipe. After the spraying device is used, chlorine gas is introduced into the absorption tank 1 through the air inlet 11 and reacts with the reaction liquid inside. Once the high-pressure nozzle 221 on the spray pipe 22 is activated, it sprays the reaction liquid in a mist form, effectively absorbing any overflowing chlorine gas and preventing leakage. To prevent backflow of the reacted solution, a one-way valve is installed at the air inlet 11, allowing chlorine gas to enter the absorption tank 1 while preventing the solution in the absorption tank 1 from flowing back to the air inlet 11.
[0031] Specifically, the spray pipe 22 includes a first pipe 223 and a second pipe 224, which intersect at a cross shape. Both the first pipe 223 and the second pipe 224 are equipped with high-pressure nozzles 221, which can spray the liquid in a mist form, increasing the contact area between the liquid and chlorine gas and promptly absorbing any overflowing chlorine gas. An inlet 222 is located at the intersection of the first pipe 223 and the second pipe 224, and is connected to the high-pressure nozzle 221. The inlet 222 is equipped with an adapter 225, which is rotatably connected to the inlet 222. Since the rotation of the support frame 21 drives the spray pipe 22 to rotate, the rotatable adapter 225 is provided. When the injection pipe is connected, even if the support frame 21 rotates, the injection pipe will not become tangled.
[0032] Furthermore, the spray pipe 22 is also equipped with a drive nozzle 226, which faces the side wall of the absorption tank 1 at the open position 12. After the liquid sprayed by the drive nozzle 226 hits the side wall at the open position 12, it will generate a recoil force, which can drive the support frame 21 to rotate, thereby driving the spray pipe 22 to rotate, realizing rotating spraying, which makes the spraying area larger and is more conducive to absorbing the overflowing chlorine gas.
[0033] Specifically, the support frame 21 includes a top surface 211 and a bottom surface 212. The first pipe 223 and the second pipe 224 are both installed on the bottom surface 212 of the support frame 21. The drive nozzle 226 is located on one side of the first pipe 223 or the second pipe 224. In this embodiment, the intersection of the first pipe 223 and the second pipe 224 is the center of the support frame 21. The drive nozzle 226 is located on one side of the first pipe 223 and is a pressure booster head. The extension direction of the drive nozzle 226 forms an angle with the direction of the first pipe 223. There are two drive nozzles 226, both installed on the first pipe 223, and the two drive nozzles 226 are centrally symmetrical about the center of the support frame 21. When the liquid sprayed from the nozzle 226 hits the side wall at the open position 12, it generates a recoil force, which in turn drives the support frame 21 to rotate, thereby rotating the spray pipe 22 to achieve rotating spraying. This results in a larger spraying area, which is beneficial for absorbing the overflowing chlorine gas.
[0034] In other embodiments, both drive nozzles 226 are mounted on the second pipe 224, and the two drive nozzles 226 are centrally symmetrical about the center of the support frame 21. The difference between this embodiment and the previous embodiments lies in the mounting position of the drive nozzles 226; the remaining functions and effects are the same as in the previous embodiments, and therefore will not be repeated here.
[0035] In this embodiment, before using the spraying device, the support frame 21 is first installed on the rotating bearing 13, ensuring that the spray pipe 22 on the support frame 21 faces downwards and the injection port 222 faces upwards. Then, a portion of the reaction liquid is injected into the absorption tank 1, and the injection port 222 is connected to the injection pipe. After the spraying device is used, chlorine gas is introduced into the absorption tank 1 through the gas inlet 11 and reacts with the reaction liquid inside the absorption tank 1. Once the high-pressure nozzle 221 on the spray pipe 22 is activated, it can spray the reaction liquid in a mist form, driving the nozzle 226 to spray liquid towards the side wall of the top of the absorption tank 1 at the open position 12. The sprayed liquid, upon hitting the side wall at the open position 12, generates a recoil force, which in turn drives the support frame 21 to rotate, thereby rotating the spray pipe 22 and achieving rotating spraying. This results in a larger spray area, effectively absorbing any overflowing chlorine gas and preventing chlorine gas leakage.
[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
