Description

Technical Field

[0001] The invention relates to the technical field of trichlorosilane discharge heat exchange, in particular to a trichlorosilane discharge heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It sets a heat-conducting wall between the two fluids to transfer the heat from the high-temperature fluid to the low-temperature fluid, thereby achieving the purpose of heat exchange and temperature regulation. When trichlorosilane is being processed, the temperature is usually around 280℃-320℃.

[0003] Patent application number CN202223385881.2 discloses a trichlorosilane discharge heat exchanger, including a water tank; a heat exchange device is installed above the water tank, and a plurality of short rods for supporting the heat exchange device are installed on the upper end surface of the water tank. A plurality of U-shaped tubes are installed in the heat exchange device, and both ends of the plurality of U-shaped tubes extend out of the side of the heat exchange device. A rectangular box is installed on the upper end surface of the water tank, and one end of the upper end of the plurality of U-shaped tubes is commonly connected to a horizontal tube, and one end of the horizontal tube extends into the rectangular box.

[0004] In summary, when the cooling water in the U-shaped tube comes into contact with the high-temperature trichlorosilane fluid, scale is easily formed inside the U-shaped tube. As the scale continues to accumulate on the inner wall of the U-shaped tube, it will hinder the heat transfer between the fluid inside the tube and the fluid outside the tube, resulting in a decrease in heat exchange efficiency, and then the cooling water will be unable to effectively cool the trichlorosilane fluid.

[0005] To this end, we proposed a trichlorosilane discharge heat exchanger. Summary of the Invention

The outer surface of the discharge pipe 107 is fixedly sleeved with fins 112. The fins 112 can greatly increase the contact area between the discharge pipe 107 and the condensed water, thereby facilitating heat exchange of the discharge pipe 107. The inner wall of the heat exchange furnace 108 is fixedly connected to a first fixing ring 110, and a groove 111 is provided on the inner wall of the first fixing ring 110. The outer wall of the heat exchange furnace 108 away from the first fixing ring 110 is fixedly connected to a water inlet pipe 113. The top of the heat exchange furnace 108 is provided with an auxiliary mechanism 3, which also includes:

[0034] The heat exchange mechanism 2 includes a rotating frame 201 that is slidably connected to the first fixed ring 110. The outer wall of the rotating frame 201 is fixedly connected to a motor 202. The output end of the motor 202 is fixedly connected to a driving wheel 203. The driving wheel 203 is rotatably connected to the inner wall of the groove 111. The bottom of the rotating frame 201 is fixedly connected to a stirring rod 205. The inner wall of the rotating frame 201 is fixedly connected to a tilting rod 204. The inner wall of the rotating frame 201 is rotatably connected to a cleaning roller 206 through a rotating shaft. The cleaning roller 206 is connected to the heat exchange mechanism 2. The inner wall of the furnace 108 is connected in a rolling manner. When the trichlorosilane fluid inside the discharge pipe 107 needs to be cooled, the heat exchange mechanism 2 can be used to allow the cooling water in the heat exchange furnace 108 to cool the discharge pipe 107. At the same time, the inner wall of the heat exchange furnace 108 and the outer wall of the discharge pipe 107 are cleaned by the cleaning roller 206 and the cleaning rod 210 to prevent scale from adhering to the outer wall of the discharge pipe 107, thereby improving the efficiency of cooling and heat exchange of the cooling water on the discharge pipe 107, and thus being able to effectively cool the trichlorosilane fluid.

[0035] A connecting rod 105 is fixedly sleeved on the outer surface of the feed pipe 106, and the connecting rod 105 serves as an auxiliary support for the feed pipe 106. The end of the connecting rod 105 away from the feed pipe 106 is fixedly connected to the first support block 104, and the top outer wall of the heat exchange furnace 108 is fixedly connected to the second support block 109, and the outer wall of the second support block 109 is fixedly connected to the second fixing ring 116.

[0036] The inner wall of the second fixed ring 116 is fixedly connected to the heat exchange furnace 108, and the end of the second fixed ring 116 away from the heat exchange furnace 108 is fixedly connected to the support column 117, and the end of the support column 117 away from the second fixed ring 116 is fixedly connected to the first fixed block 102. The outer surface of the end of the discharge pipe 107 away from the heat exchange furnace 108 is fixedly sleeved with a connecting ring 114, and the top outer wall of the connecting ring 114 is fixedly connected with a thermometer 115, which is used to measure the temperature of the discharge pipe 107 after heat exchange.

[0037] The working principle of this embodiment is as follows: when it is necessary to cool the trichlorosilane fluid inside the discharge pipe 107, the heat exchange mechanism 2 can be used to cool the discharge pipe 107 using the cooling water in the heat exchange furnace 108. During this process, the inner wall of the heat exchange furnace 108 and the outer wall of the discharge pipe 107 are cleaned by the cleaning roller 206 and the cleaning rod 210 to prevent scale from adhering to the outer wall of the discharge pipe 107, thereby improving the cooling and heat exchange efficiency of the cooling water on the discharge pipe 107, and thus effectively cooling the trichlorosilane fluid. At the same time, the motor 202 causes the rotating frame 201 to slide along the inner wall of the first fixed ring 110 through the driving wheel 203, and stirs the coolant inside the heat exchange furnace 108 with the help of the tilting rod 204 and the stirring blade 208 fixedly connected to the inner wall of the rotating frame 201 to prevent local overheating, so that the coolant can quickly achieve uniform temperature distribution in the heat exchange furnace 108.

[0038] Example 2: Please refer to Figure 4-Figure 7 Based on the first embodiment, the present invention provides a technical solution: an elastic rod 207 is fixedly connected to the inner wall of the top of the rotating frame 201. The number of the elastic rods 207 is three, and the three elastic rods 207 are evenly distributed inside the rotating frame 201. The inner wall of the elastic rod 207 is fixedly connected to a stirring blade 208, and the stirring blade 208 stirs the condensed water in the heat exchange furnace 108.

[0039] A cleaning rod 210 is fixedly connected to the outer wall of the elastic rod 207 away from the rotating frame 201. The cleaning rod 210 is slidably connected to the outer wall of the discharge pipe 107 away from the elastic rod 207. A cleaning tooth 209 is fixedly connected to the outer wall of the elastic rod 207 close to the cleaning roller 206. The cleaning teeth 209 clean the outer wall of the cleaning roller 206, thereby ensuring the cleanliness of the cleaning roller 206.

[0040] The working principle of this embodiment is as follows: the motor 202 causes the rotating frame 201 to slide along the inner wall of the first fixed ring 110 through the driving wheel 203, and the inclined rod 204 and the stirring blade 208 fixedly connected to the inner wall of the rotating frame 201 move with the rotating frame 201 to stir the coolant inside the heat exchange furnace 108. The stirring action can prevent local overheating of the coolant and enable the coolant to quickly reach a uniform temperature distribution in the heat exchange furnace 108. When the stirring blade 208 comes into contact with the condensed water, it will deform, and this deformation will cause vibration. When cleaning the outer wall of the cleaning roller 206, the cleaning teeth 209 fixedly connected to the inner wall of the elastic rod 207 come into play. At this time, with the help of the vibration generated by the stirring blade 208 and the rotation of the rotating frame 201, the elastic rod 207 will also vibrate. This vibration and the rotation of the rotating frame 201 work together to realize the self-cleaning function of the cleaning teeth 209 and the cleaning rod 210, prevent scale from adhering to the cleaning teeth 209 and the cleaning rod 210, and ensure that the device can operate continuously and effectively.

[0041] Example 3: Please refer to Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the auxiliary mechanism 3 includes an outlet pipe 301 fixedly connected to the heat exchange furnace 108, the end of the outlet pipe 301 away from the heat exchange furnace 108 is fixedly connected to an annular pipe 302, the annular pipe 302 is wrapped around the outer surface of the feed pipe 106, the end of the annular pipe 302 away from the outlet pipe 301 is fixedly connected to a connecting pipe 303, the end of the connecting pipe 303 away from the annular pipe 302 passes through the second fixing ring 116 and is fixedly connected to the heat exchange furnace 108, the outlet pipe 301 transports water vapor from the inside of the heat exchange furnace 108 to the side of the annular pipe 302, and the outer wall of the feed pipe 106 is wrapped by the annular pipe 302 for heating, thereby preheating the solution inside the feed pipe 106.

[0042] A check valve 310 is fixedly connected to the outer wall of one end of the outlet pipe 301 close to the annular pipe 302, and a collecting pipe 309 is fixedly connected to the outer wall of the bottom of the annular pipe 302. The collecting pipe 309 can drain the liquefied condensed water to the connecting pipe 303, thereby introducing the liquefied condensed water into the heat exchange furnace 108 through the connecting pipe 303. The collecting pipe 309 is fixedly connected to the connecting pipe 303 at one end away from the arc pipe. The outer surface of the outlet pipe 301 is fixedly sleeved with a second fixed block 304, and the outer surface of the connecting pipe 303 is fixedly sleeved with a third fixed block 305.

[0043] The outer wall of the second fixed block 304 close to the third fixed block 305 is fixedly connected to a spring 308, and the end of the spring 308 away from the second fixed block 304 is fixedly connected to the third fixed block 305, and the inner wall of the second fixed block 304 is rotatably connected to the first rotating rod 306 via a rotating shaft, and the inner wall of the end of the first rotating rod 306 away from the second fixed block 304 is rotatably connected to the second rotating rod 307 via a rotating shaft. The second rotating rod 307 and the third rotating rod play an auxiliary stabilizing role for the second fixed block 304 and the third fixed block 305 on both sides, thereby reducing the influence of thermal expansion and contraction on the outlet pipe 301 and the connecting pipe 303, and the end of the second rotating rod 307 away from the first rotating rod 306 is fixedly connected to the third fixed block 305.

[0044] The working principle of this embodiment is as follows: when high-temperature trichlorosilane fluid passes through the discharge pipe 107, heat is transferred. At this time, the discharge pipe 107 containing the trichlorosilane fluid is cooled by the coolant. As the coolant absorbs heat, the coolant evaporates due to the heat. The evaporated high-temperature water vapor is discharged to the annular tube 302 through the outlet pipe 301. The annular tube 302 wraps the outer wall of the feed pipe 106. The heat of the high-temperature water vapor is used to preheat the solution inside the feed pipe 106 to achieve energy recovery. At the same time, the second rotating rod 307 and the third rotating rod respectively play an auxiliary stabilizing role for the second fixed block 304 and the third fixed block 305 on both sides, thereby reducing the adverse effects of thermal expansion and contraction on the outlet pipe 301 and the connecting pipe 303, ensuring that the entire system can still operate stably under temperature changes.
