Description

Technical Field

[0001] The utility model relates to a chlorine gas distribution device, belonging to the field of chlorinated paraffin processing equipment. Background Art

[0002] Chlorinated paraffin is an important organic chemical raw material. During the processing of chlorinated paraffin, a large amount of high-temperature chlorine gas will be generated. In order to reduce the emission of chlorine gas and improve the utilization efficiency of chlorine gas, chlorinated paraffin manufacturers usually adopt a chlorine gas recovery device to recover and process the chlorine gas in the waste gas. Through chlorine gas recovery technology, not only can resources be saved and production costs be reduced, but also it is beneficial to reduce environmental pollution, which conforms to the production concept of sustainable development. This technology is widely used in the chemical industry and plays an important role in environmental protection and resource conservation.

[0003] In the prior art, high-temperature chlorine gas is transported to a condenser for heat exchange, so that water molecules in the high-temperature chlorine gas condense to form water droplets, thereby realizing gas-liquid separation. However, when high-temperature chlorine gas is transported to the inside of a heat exchange tube for heat exchange, the heat exchange effect of the gas flow close to the heat exchange tube during transportation is obvious, but the heat exchange effect of the gas flow transported at the central position of the pipe fitting is not obvious. Therefore, it is necessary to reduce the gas flow transportation efficiency to ensure sufficient heat exchange. Although the gas-liquid separation effect is achieved, the chlorine gas recovery efficiency is also reduced.

[0004] In summary, the utility model provides a chlorine gas distribution device to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a chlorine gas distribution device to solve the problem of low chlorine gas recovery efficiency caused by the slow gas-liquid separation speed of high-temperature chlorine gas mentioned in the above background art.

[0006] To achieve the above purpose, the utility model is realized by the following technical solutions: A chlorine gas distribution device includes a base and a heat exchanger. Support seats are fixedly connected to the four peripheries of the top of the base. A heat exchange box is fixedly connected between the tops of the four support seats. The heat exchanger is fixedly installed on one side of the heat exchange box. Gas-liquid separation tube groups penetrate between the top peripheries and the bottom peripheries of the inner wall of the heat exchange box. A water collection tank is fixedly connected to the top of the base between the drainage ends of the four gas-liquid separation tube groups. A distribution cylinder is communicated above the heat exchange box between the exhaust ends of the four gas-liquid separation tube groups. An air outlet pipe is communicated with the top of the distribution cylinder. An air inlet pipe penetrates through the bottom of the distribution cylinder.

[0007] Furthermore, the liquid inlet end and the liquid outlet end of the heat exchanger are both communicated with the inside of the heat exchange box through pipelines, and the air inlet pipe is fixedly connected to the distribution cylinder.

[0008] Furthermore, the gas-liquid separation pipe group includes a tee pipe which is connected to one side of the top of the water collecting tank. Both ends of the tee pipe penetrate through the heat exchange tank and extend into the interior of the heat exchange tank. A heat exchange pipe is fixedly connected between both ends of the tee pipe and located inside the heat exchange tank. The two ends of the heat exchange pipe are respectively communicated with a first distribution pipe and a second distribution pipe. The first distribution pipe sequentially penetrates through the top of the inner wall of the heat exchange tank and one side of the distribution cylinder and extends into the interior of the distribution cylinder. One end of the second distribution pipe sequentially penetrates through the top of the inner wall of the heat exchange tank and one side of the distribution cylinder and extends to one side of the surface of the intake pipe.

[0009] Furthermore, a solenoid valve is installed at the end of the tee pipe connected to the water collecting tank, and the heat exchange pipe is in a serpentine tubular shape.

[0010] Furthermore, the first distribution pipe is communicated with the distribution cylinder, and the second distribution pipe is communicated with the intake pipe.

[0011] Furthermore, the first distribution pipe is fixedly connected to the heat exchange tank, and the second distribution pipe is fixedly connected to the heat exchange tank.

[0012] Furthermore, a drain pipe is communicated with the bottom of one side of the water collecting tank, and a solenoid valve is installed on the drain pipe.

[0013] Advantages of the present utility model:

[0014] It is sent to the external chlorine recovery equipment through the air outlet pipe at the top of the distribution cylinder. The high-temperature chlorine gas is evenly distributed and transported into the heat exchange pipes inside the four gas-liquid separation pipe groups through the distribution cylinder for cooling and heat exchange at the same time. After heat exchange, it can be transported back into the interior of the distribution cylinder and centrally discharged through the air outlet pipe, improving the gas contact area, increasing the gas-liquid separation effect, and not reducing the transported gas flow rate, thereby ensuring the chlorine recovery efficiency.

[0015] Both ends of the tee pipe are respectively communicated with the bent pipe surfaces at the bottom of the heat exchange pipe. The water droplets generated by condensation on the inner wall of the heat exchange pipe slide down along the gravity and are transported into the interior of the tee pipe. Then, by opening the valves on the four tee pipes, the liquid collected inside the tee pipe can be centrally transported into the interior of the water collecting tank for centralized collection. By opening the valve of the drain pipe on the water collecting tank, the sewage can be centrally discharged, facilitating the centralized recovery of the sewage generated by the later chlorine treatment and improving the recovery convenience of the waste in the production of chlorinated paraffin.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

Support bases 2 are fixedly connected to the four peripheries of the top of the base 1. A heat exchange box 3 is fixedly connected between the tops of the four support bases 2. The heat exchanger 8 is fixedly installed on one side of the heat exchange box 3. Gas-liquid separation pipe groups 4 penetrate between the peripheries of the inner wall top and the inner wall bottom of the heat exchange box 3. A water collection tank 9 is fixedly connected between the drainage ends of the four gas-liquid separation pipe groups 4 and on the top of the base 1. A distribution cylinder 5 is communicated between the exhaust ends of the four gas-liquid separation pipe groups 4 and above the heat exchange box 3. The top of the distribution cylinder 5 is communicated with an outlet pipe 6. The bottom of the distribution cylinder 5 penetrates through an inlet pipe 7. The liquid inlet end and the liquid outlet end of the heat exchanger 8 are both connected to the inside of the heat exchange box 3 through pipelines. The inlet pipe 7 is fixedly connected to the distribution cylinder 5. The heat exchanger 8 is a device for heat transfer, mainly used for heat exchange between fluids or between a fluid and a solid. The function of the heat exchanger 8 is to transfer heat from one fluid to another fluid to achieve energy transfer and utilization. This heat exchanger 8 is a tubular heat exchanger, which can extract the heat exchange liquid inside the heat exchange box 3, cool it and then transport it back to the inside of the heat exchange box 3. Thus, the high-temperature chlorine gas generated during the production of chlorinated paraffin in the heat exchange pipe 42 can be cooled by the continuously cooled liquid, so as to realize the gas-liquid separation of the high-temperature chlorine gas. One end of the inlet pipe 7 located outside the distribution cylinder 5 is communicated with an external chlorine gas transmission pipeline, so that the high-temperature chlorine gas generated during the production of chlorinated paraffin can be transported into the inside of the inlet pipe 7. The other end of the inlet pipe 7 is blocked. The other end of the outlet pipe 6 is communicated with an external chlorine gas recovery device.

[0024] Please refer toFigures 2-4 , the gas-liquid separation pipe group 4 includes a three-way pipe 41, the three-way pipe 41 is connected to one side of the top of the water collection tank 9, both ends of the three-way pipe 41 penetrate through the heat exchange tank 3 and extend into the interior of the heat exchange tank 3, and a heat exchange pipe 42 is fixedly connected between the two ends of the three-way pipe 41 and located inside the heat exchange tank 3. The two ends of the heat exchange pipe 42 are respectively communicated with a first distribution pipe 43 and a second distribution pipe 44. The first distribution pipe 43 sequentially penetrates through the top of the inner wall of the heat exchange tank 3 and one side of the distribution cylinder 5 and extends into the interior of the distribution cylinder 5. One end of the second distribution pipe 44 sequentially penetrates through the top of the inner wall of the heat exchange tank 3 and one side of the distribution cylinder 5 and extends to one side of the pipe surface of the intake pipe 7. The two ends of the three-way pipe 41 are respectively communicated with the bent pipe surfaces at the bottom of the heat exchange pipe 42. The water droplets generated by condensation on the inner wall of the heat exchange pipe 42 slide downwards due to gravity and are conveyed into the interior of the three-way pipe 41. An electromagnetic valve is installed at one end of the three-way pipe 41 communicated with the water collection tank 9. The heat exchange pipe 42 is in a serpentine tubular shape. The first distribution pipe 43 is communicated with the distribution cylinder 5, the second distribution pipe 44 is communicated with the intake pipe 7, the first distribution pipe 43 is fixedly connected with the heat exchange tank 3, the second distribution pipe 44 is fixedly connected with the heat exchange tank 3. A drain pipe is communicated with the bottom of one side of the water collection tank 9, and an electromagnetic valve is installed on the drain pipe.

[0025] Specific implementation method: By opening the external chlorine delivery pipeline, the high-temperature chlorine gas generated in the production of chlorinated paraffin is transported into the interior of the intake pipe 7. Through the intake pipe 7, the high-temperature chlorine gas is evenly transported into the second distribution pipes 44 inside the four gas-liquid separation pipe groups 4. Then, through the four second distribution pipes 44, the high-temperature chlorine gas is simultaneously transported into the interior of the four heat exchange pipes 42. At the same time, the heat exchanger 8 is started. This heat exchanger 8 is a tubular heat exchanger, which can extract the heat exchange liquid inside the heat exchange tank 3, cool it, and then transport it back into the interior of the heat exchange tank 3. Thus, the high-temperature chlorine gas generated during the production of chlorinated paraffin inside the heat exchange pipes 42 can be cooled by the continuously cooled liquid, thereby realizing the gas-liquid separation of the high-temperature chlorine gas. The low-temperature chlorine gas after gas-liquid separation is simultaneously transported into the interior of the distribution cylinder 5 through the first distribution pipes 43 inside the four gas-liquid separation pipe groups 4, and then discharged to the external chlorine recovery equipment through the outlet pipe 6 at the top of the distribution cylinder 5. The high-temperature chlorine gas is evenly distributed and transported into the heat exchange pipes 42 inside the four gas-liquid separation pipe groups 4 for simultaneous cooling and heat exchange, and after heat exchange, it can be transported back into the interior of the distribution cylinder 5 and discharged centrally through the outlet pipe 6, increasing the gas contact area, enhancing the gas-liquid separation effect, and not reducing the gas flow rate during transportation. Thus, the chlorine recovery efficiency can be ensured. Both ends of the three-way pipe 41 are connected to the bent pipe surfaces at the bottoms of the heat exchange pipes 42. The water droplets generated by condensation on the inner walls of the heat exchange pipes 42 slide down due to gravity and are transported into the interior of the three-way pipe 41. Then, by opening the valves on the four three-way pipes 41, the liquid collected inside the three-way pipe 41 can be centrally transported into the interior of the water collection tank 9 for centralized collection. By opening the valve of the drain pipe on the water collection tank 9, the sewage can be discharged centrally, facilitating the centralized recovery of the sewage generated during the later chlorine treatment and improving the convenience of recovering the waste generated in the production of chlorinated paraffin.
