AI Technical Summary
In existing reactor exhaust gas absorption devices, exhaust gas tends to accumulate below the shower head after entering the absorption device, resulting in high local exhaust gas concentration and low absorption efficiency of the absorption liquid.
A waste gas absorption vessel for the synthesis of bromochlorohydantoin was designed, comprising a motor-driven rotating shaft and a mounting block. The exhaust port reduces the local waste gas concentration as it rotates, and absorbent liquid is sprayed out through a spray nozzle to absorb the waste gas. At the same time, fan blades are used to increase airflow to extend the waste gas treatment time.
It effectively reduced the local concentration of exhaust gas, improved the absorption efficiency and absorption rate of exhaust gas, and achieved more efficient exhaust gas treatment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a waste gas absorption vessel for the synthesis process of bromochlorohydantoin. Background Technology
[0002] Bromochlorohydantoin, also known as Bacterial and Algae Clear, chemical name 1-bromo-3-chloro-5,5-dimethylhydantoin, molecular formula C5H6BrClN2O2, is a white powder. It is a disinfectant with specific properties, used for industrial water treatment and disinfection of mineral baths. Only 1-2 ppm is needed for disinfection of indoor and outdoor swimming pools. It can also be used in various water treatments, toilet disinfection and deodorization, disinfection and bleaching, and in agriculture for disinfection and sterilization of flowers and seeds, as well as in aquaculture and fruit preservation. Bromochlorohydantoin can be compressed into tablets, and weighing and packaging these tablets facilitates transportation and quantitative use.
[0003] A search revealed a utility model patent with application number "202221790326.5" disclosing a reactor waste gas absorption device, including an absorption tank. The absorption tank is a cylindrical hollow tank structure, equipped with an inlet pipe and an outlet pipe. The outlet pipe is located at the bottom of the side wall of the absorption tank, while the inlet pipe extends into the tank from the top. The bottom of the side wall of the absorption tank also has a waste gas inlet pipe and an outlet pipe. The waste gas inlet pipe passes through the side wall of the absorption tank and extends into its interior. The outlet pipe is located at the top of the absorption tank. One end of the waste gas inlet pipe extending into the tank is connected to a shower head, with the outlet facing the bottom of the absorption tank. This utility model provides a reactor waste gas absorption device with good waste gas absorption effect, high waste gas absorption efficiency, and simple absorbent replacement operation.
[0004] The aforementioned reactor exhaust gas absorption device increases the gas's travel distance and residence time, further enhancing the contact time between the exhaust gas and the absorbent liquid, thereby improving the absorption effect. However, in this device, the exhaust gas accumulates below the shower head after entering the absorption unit, easily leading to high local exhaust gas concentrations and low absorption efficiency of the absorbent liquid.
[0005] In summary, there is an urgent need for a waste gas absorption vessel for the synthesis of bromochlorohydantoin to solve the above problems. Utility Model Content
[0006] To overcome the above shortcomings, this utility model provides a waste gas absorption vessel for the synthesis of bromochlorohydantoin, which solves the problems of existing waste gas absorption devices in reactors where waste gas accumulates below the shower head after entering the absorption device, easily leading to high local waste gas concentration and low absorption efficiency of the absorption liquid.
[0007] This utility model is implemented as follows:
[0008] A waste gas absorption vessel for the synthesis of bromochlorohydantoin includes a side wall, a top plate, and a bottom plate. An outlet pipe is fixedly installed above the top plate, and a waste gas inlet pipe and a drain pipe are fixedly installed at the bottom of the side wall. The waste gas inlet pipe is located on one side of the side wall, and the drain pipe is located on the side of the side wall away from the waste gas inlet pipe.
[0009] A motor is fixedly installed above the top plate, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft extends through the top plate into the interior of the waste gas absorption vessel. A mounting block is fixedly installed at the bottom of the rotating shaft. The mounting block is rotatably installed on the top of the waste gas inlet pipe, and an outlet is fixedly installed on the side wall of the mounting block.
[0010] A support rod arranged in a circular array is fixedly installed above the rotating shaft, and several spray nozzles are fixedly installed below the support rods, with the spray nozzles facing the mounting block.
[0011] Preferably, a fan blade is also mounted on the rotating shaft, and the fan blade is disposed between the mounting block and the support rod.
[0012] Preferably, the fan blades direct the airflow from top to bottom.
[0013] The beneficial effects of this utility model compared to the prior art are:
[0014] 1. The waste gas absorption vessel for the synthesis of bromochlorohydantoin shown in this utility model has a motor fixedly installed above the top plate. The output end of the motor is fixedly connected to a rotating shaft, which extends through the top plate into the interior of the waste gas absorption vessel. A mounting block is fixedly installed at the bottom of the rotating shaft. The mounting block is rotatably installed on the top of the waste gas inlet pipe. An outlet is fixedly installed on the side wall of the mounting block. The outlet rotates with the operation of the motor, thereby rotating and spraying out waste gas, which can also reduce the local waste gas concentration and thus improve the waste gas absorption efficiency.
[0015] 2. The waste gas absorption vessel for the bromochlorohydantoin synthesis process shown in this utility model is equipped with fan blades on the rotating shaft. The rotation of the fan blades can improve the airflow inside the waste gas absorption vessel, reduce the local waste gas concentration, and the airflow direction of the fan blades is from top to bottom, which can effectively reduce the efficiency of waste gas rise, thereby extending the waste gas treatment time and improving the waste gas absorption rate.

[0022] Example 1:
[0023] Please see Figures 1-3 This utility model provides a technical solution:
[0024] Used in the waste gas absorption vessel of the bromochlorohydantoin synthesis process, such as Figure 1 As shown, it includes a side wall 1, a top plate 5 and a bottom plate 6, with an air outlet pipe 3 fixedly installed above the top plate 5;
[0025] like Figure 2 As shown, an exhaust gas inlet pipe 4 and a liquid drain pipe 8 are fixedly installed at the bottom of the side wall 1. The exhaust gas inlet pipe 4 is located on one side of the side wall 1, and the liquid drain pipe 8 is located on the side of the side wall 1 away from the exhaust gas inlet pipe 4.
[0026] like Figure 3As shown, a motor 2 is fixedly installed above the top plate 5, and a rotating shaft 7 is fixedly connected to the output end of the motor 2. The rotating shaft 7 extends through the top plate 5 into the interior of the waste gas absorption vessel. A mounting block 10 is fixedly installed at the bottom of the rotating shaft 7. The mounting block 10 is rotatably installed on the top of the waste gas inlet pipe 4, and an outlet 9 is fixedly installed on the side wall 1 of the mounting block 10. The outlet 9 rotates with the operation of the motor 2, thereby rotating and spraying out waste gas, which can also reduce the local waste gas concentration and thus improve the waste gas absorption efficiency.
[0027] like Figure 3 As shown, a support rod 13 arranged in a circular array is fixedly installed above the rotating shaft 7, and several spray nozzles 12 are fixedly installed below the support rod 13. The spray nozzles 12 face the mounting block 10, and the absorbent liquid sprayed from the spray nozzles 12 can effectively absorb the exhaust gas sprayed from the outlet 9.
[0028] like Figure 3 As shown, a fan blade 11 is also installed on the rotating shaft 7. The fan blade 11 is located between the mounting block 10 and the support rod 13. The rotation of the fan blade 11 can improve the airflow inside the waste gas absorption vessel and reduce the local waste gas concentration.
[0029] Preferably, the fan blade 11 directs the airflow from top to bottom, effectively reducing the efficiency of exhaust gas ascent, thereby extending the exhaust gas treatment time and improving the exhaust gas absorption rate.
