[0024] By adopting the above technical solution, the heat inside the reactor 1 is absorbed by the heat conducting plate 51, and the heat is transferred to the heat conducting sleeve 52 through the heat conducting column 53. The cooling water in the heat conducting sleeve 52 quickly absorbs the heat of the heat conducting sleeve 52, thereby quickly reducing the temperature inside the reactor 1. Then, the cooling water in the cooling water tank 54 is sent into the heat conducting sleeve 52 through the water outlet pipe 56 by the circulating pump 55. The water that has absorbed heat in the heat conducting sleeve 52 flows back to the cooling water tank 54 through the return pipe 57, forming a cooling water circulation. The air flow rate in the heat dissipation pipe 59 is accelerated by the cooling fan 58 to accelerate the heat dissipation speed of the cooling water tank 54, so that the cooling water in the cooling water tank 54 always remains at a relatively low temperature, thereby ensuring the stability of the heat dissipation effect of the device, enabling the reactor 1 to continuously maintain a relatively low temperature, and ensuring the stable progress of the reaction.

[0025] Specifically, a fixed frame is arranged on the surface of the cooling fan 58, and a dust-proof net is arranged on the side of the fixed frame away from the cooling water tank 54.

[0027] When this embodiment is in use: the heat inside the reactor 1 is absorbed by the heat conducting plate 51, and the heat is transferred to the heat conducting sleeve 52 through the heat conducting column 53. The cooling water in the heat conducting sleeve 52 quickly absorbs the heat of the heat conducting sleeve 52, thereby quickly reducing the temperature inside the reactor 1. Then, the cooling water in the cooling water tank 54 is sent into the heat conducting sleeve 52 through the water outlet pipe 56 by the circulating pump 55. The water that has absorbed heat in the heat conducting sleeve 52 flows back to the cooling water tank 54 through the return pipe 57, forming a cooling water circulation. The air flow rate in the heat dissipation pipe 59 is accelerated by the cooling fan 58 to accelerate the heat dissipation speed of the cooling water tank 54, so that the cooling water in the cooling water tank 54 always remains at a relatively low temperature, thereby ensuring the stability of the heat dissipation effect of the device, enabling the reactor 1 to continuously maintain a relatively low temperature, and ensuring the stable progress of the reaction, improving the practicability of the device.

[0030] By adopting the above technical solution, chlorine gas enters the rotating pipe 61 from the chlorine gas inlet pipe 2 and then enters the bottom gas outlet pipe 62. By using the gas outlet holes evenly distributed on the bottom gas outlet pipe 62, the chlorine gas is evenly distributed at the bottom of the reaction kettle 1, and the chlorine gas enters the connecting ventilation pipe 63 and the side ventilation pipe 64. By using the gas outlet holes evenly distributed thereon, the chlorine gas is evenly distributed inside the reaction kettle 1, increasing the contact area between the chlorine gas and the reaction liquid. Then, the stirring motor 67 drives the driving gear 66 to rotate. The rotation of the driving gear 66 drives the driven gear 65 to rotate. The rotation of the driven gear 65 drives the rotating pipe 61 to rotate. The rotation of the rotating pipe 61 drives the bottom gas outlet pipe 62, the connecting ventilation pipe 63 and the side ventilation pipe 64 to rotate, uniformly mixing the chlorine gas and the reaction liquid. The combined action of multiple measures improves the rate of the chlorination reaction.

[0031] Specifically, protective sleeves are provided outside the stirring motor 67, the driven gear 65 and the driving gear 66.

[0032] By adopting the above technical solution, the protective sleeves outside the stirring motor 67, the driven gear 65 and the driving gear 66 play a protective role for the stirring motor 67, the driven gear 65 and the driving gear 66.

[0033] Specifically, a sealing sleeve is provided at the intersection of the rotating pipe 61 and the chlorine gas inlet pipe 2, and a rotating groove is provided between the sealing sleeve and the rotating pipe 61.

[0034] By adopting the above technical solution, the sealing sleeve at the intersection of the rotating pipe 61 and the chlorine gas inlet pipe 2 and the rotating groove between the sealing sleeve and the rotating pipe 61 prevent chlorine gas leakage.

[0035] When this embodiment is in use: Chlorine gas enters the rotating pipe 61 from the chlorine gas inlet pipe 2 and then enters the bottom gas outlet pipe 62. By using the gas outlet holes evenly distributed on the bottom gas outlet pipe 62, the chlorine gas is evenly distributed at the bottom of the reaction kettle 1, and the chlorine gas enters the connecting ventilation pipe 63 and the side ventilation pipe 64. By using the gas outlet holes evenly distributed thereon, the chlorine gas is evenly distributed inside the reaction kettle 1, increasing the contact area between the chlorine gas and the reaction liquid. Then, the stirring motor 67 drives the driving gear 66 to rotate. The rotation of the driving gear 66 drives the driven gear 65 to rotate. The rotation of the driven gear 65 drives the rotating pipe 61 to rotate. The rotation of the rotating pipe 61 drives the bottom gas outlet pipe 62, the connecting ventilation pipe 63 and the side ventilation pipe 64 to rotate, uniformly mixing the chlorine gas and the reaction liquid. The combined action of multiple measures improves the rate of the chlorination reaction.

[0036] The circulation pump 55 in the present utility model is an existing publicly disclosed technology, and the selected model is CDLF16-20.

[0037] The cooling fan 58 in the present utility model is a publicly known prior art, and the selected model is 109S025UL.

[0038] The working principle and usage process of the present utility model: When the chlorination reactor of the present utility model conducts a chlorination reaction in chemical production, chlorine is first introduced into the rotating pipe 61 from the chlorine inlet pipe 2, and the chlorine enters the bottom outlet pipe 62. By using the uniformly distributed air outlets on the bottom outlet pipe 62, the chlorine is evenly distributed at the bottom of the reaction kettle 1, and enters the connecting ventilation pipe 63 and the side ventilation pipe 64 through the chlorine. By using the uniformly distributed air outlets thereon, the chlorine is evenly distributed inside the reaction kettle 1, increasing the contact area between the chlorine and the reaction liquid. Then, the stirring motor 67 drives the driving gear 66 to rotate. The rotation of the driving gear 66 drives the driven gear 65 to rotate. The rotation of the driven gear 65 drives the rotating pipe 61 to rotate. The rotation of the rotating pipe 61 drives the bottom outlet pipe 62, the connecting ventilation pipe 63, and the side ventilation pipe 64 to rotate, uniformly mixing the chlorine and the reaction liquid. The combined action of multiple measures improves the rate of the chlorination reaction. During the chlorination reaction process, the heat inside the reaction kettle 1 is absorbed by the heat conducting plate 51, and the heat is transferred to the heat conducting sleeve 52 through the heat conducting column 53. The cooling water in the heat conducting sleeve 52 quickly absorbs the heat of the heat conducting sleeve 52, thereby quickly reducing the temperature inside the reaction kettle 1. Then, the cooling water in the cooling water tank 54 is sent into the heat conducting sleeve 52 through the water outlet pipe 56 by the circulating pump 55. The water that has absorbed heat in the heat conducting sleeve 52 flows back to the cooling water tank 54 through the return pipe 57, forming a cooling water cycle. The air flow rate in the heat dissipation pipeline 59 is accelerated by the cooling fan 58 to accelerate the heat dissipation speed of the cooling water tank 54, so that the cooling water in the cooling water tank 54 always maintains a relatively low temperature, thereby ensuring the stability of the heat dissipation effect of the device, enabling the reaction kettle 1 to continuously maintain a relatively low temperature, ensuring the stable progress of the reaction, improving the practicability of the device. Finally, the product generated by the reaction is discharged through the discharge port 3.
