Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation, and in particular relates to a silicon carbide gas-liquid separation anti-entrainment heat exchanger. Background Technology

[0002] In chemical, materials, and other industrial fields, the separation and treatment of silicon carbide gas is a crucial step. Traditional silicon carbide gas separation equipment often employs only a single separation method, such as relying solely on condensation or filtration. Simple condensation cannot guarantee sufficient liquefaction of water vapor, resulting in low separation efficiency; while simple filtration has limited effectiveness in separating liquid water and gas, easily leading to liquid water being carried away with the gas (entrainment), failing to guarantee the dryness of the output gas. Therefore, a silicon carbide gas-liquid separation anti-entrainment heat exchanger combining condensation, centrifugation, and filtration methods was designed. Utility Model Content

[0003] The purpose of this invention is to provide a silicon carbide vapor-liquid separation anti-entrainment heat exchanger, which has a multi-stage processing mechanism of water-cooled liquefaction, centrifugal separation and filtration. Through components such as spiral tubes, centrifugal components, filter components and intelligent monitoring (sensors, alarm system), it achieves efficient separation and anti-entrainment of silicon carbide gas, and solves the problem of low efficiency of single separation in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a silicon carbide vapor-liquid separation anti-entrainment heat exchanger, including a separation chamber. One end of the separation chamber is fixedly connected to a feed pipe and a drain pump at its bottom, and the other end of the separation chamber is fixedly connected to a discharge pipe at its upper side. The separation chamber is connected to a water cooling assembly for liquefying water in the silicon carbide vapor. The separation chamber is also connected to a centrifugal assembly for throwing the liquefied water onto the inner wall of the separation chamber and then discharging it from the drain pump.

[0005] Preferably, the water-cooling assembly includes a spiral tube, which is disposed in the separation chamber. One end of the spiral tube is fixedly connected to the water inlet pipe, and the other end of the spiral tube is fixedly connected to the water outlet pipe.

[0006] Preferably, the inlet pipe is fixedly connected to one end of the separation chamber, the outlet pipe is fixedly connected to the other end of the separation chamber, the inlet of the inlet pipe is located outside the separation chamber, and the outlet of the outlet pipe is located outside the separation chamber.

[0007] Preferably, the centrifugal assembly includes a rotating shaft and fan blades. The two ends of the rotating shaft are rotatably connected to the center of the separation chamber. A plurality of fan blades are fixedly arranged on the rotating shaft. The spiral tube surrounds the fan blades and the rotating shaft. One end of the rotating shaft is fixedly connected to the output shaft of a motor. The motor is fixed inside the motor cavity, and the motor cavity is fixed at one end of the separation chamber.

[0008] Preferably, the system also includes a filter assembly, the discharge pipe being connected to the filter assembly, which is used for secondary filtration of water within the silicon carbide vapor.

[0009] Preferably, the filter assembly includes a base, the center of which is fixedly connected to the discharge pipe, and a filter element placement slot is screwed onto the base. The upper end of the filter element placement slot is fixedly provided with a discharge port, and a water-absorbing block can be placed in the placement area formed by the filter element placement slot and the base.

[0010] Preferably, a sensor, which is a humidity sensor, is installed on the base, and the sensor's contacts are located inside the base.

[0011] Preferably, the system also includes a controller that transmits data with the sensor. The sensor monitors the humidity of the absorbent block placed in the base and filter placement slot in real time.

The alarm device is installed on the separation chamber and is electrically connected to the alarm device.

[0012] Preferably, the separation cavity also includes a connecting seat, which is fixed to the separation cavity, and the connecting seat facilitates the installation of the separation cavity.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. A multi-stage treatment mechanism of water-cooled liquefaction, centrifugal separation, and filtration is adopted. First, the heat exchange area is increased and the contact time is extended through the spiral tube in the water-cooling component to ensure that the water vapor is fully liquefied. Then, the centrifugal force generated by the centrifugal component accelerates the separation of liquid water and gas. Finally, the filter component performs secondary treatment, which effectively achieves efficient separation of water vapor in silicon carbide gas, prevents liquid water from being carried out with the gas, and ensures the dryness of the output gas.

[0015] 2. The spiral tube layout makes reasonable use of the internal space of the separation chamber, reducing the size of the equipment; the centrifugal components and the spiral tube work together without interfering with each other; the filter components adopt a detachable screw connection structure, which makes it easy to disassemble and replace the water suction block, reducing maintenance costs while ensuring sealing.

[0016] 3. An automated monitoring system is formed by controllers, sensors and alarms to monitor the humidity of the water-absorbing blocks in the filter components in real time. When the humidity exceeds the set threshold, an alarm is automatically issued to remind the user to replace the water-absorbing blocks. This effectively warns of the failure risk of the filter components, improves the operating efficiency of the equipment, and avoids excessive moisture content in the gas due to saturation of the water-absorbing blocks.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 As shown, a silicon carbide vapor-liquid separation anti-entrainment heat exchanger includes a separation chamber 5. One end of the separation chamber 5 is fixedly connected to a feed pipe 6 and a drain pump 9 at its bottom. The other end of the separation chamber 5 is fixedly connected to a discharge pipe 4 at its upper side. The separation chamber 5 is connected to a water cooling assembly for liquefying water in the silicon carbide vapor. The separation chamber 5 is also connected to a centrifugal assembly for throwing the liquefied water onto the inner wall of the separation chamber 5 and then discharging it from the drain pump 9.

[0025] The specific design of the aforementioned key components will be discussed in detail below:

[0026] like Figure 2 As shown, in this embodiment, the water-cooling component cools the silicon carbide gas, causing the water vapor in it to liquefy into liquid water. The centrifugal component generates centrifugal force through rotation, throwing the liquefied water towards the inner wall of the separation chamber 5. After the liquid water gathers along the wall, the drain pump 9 starts to discharge the water, while the dried silicon carbide gas flows out from the discharge pipe 4, achieving efficient separation of water vapor in the silicon carbide gas, preventing liquid water from being carried out with the gas (anti-entrapment), and ensuring the dryness of the discharged gas. The feed pipe 6 and the discharge pipe 4 are respectively set at both ends of the separation chamber 5, forming a co-current or counter-current flow path to optimize the separation efficiency.

[0027] The water-cooling assembly includes a spiral tube 11, which is disposed in the separation chamber 5. One end of the spiral tube 11 is fixedly connected to the water inlet pipe, and the other end of the spiral tube 11 is fixedly connected to the water outlet pipe.

[0028] In this embodiment, the water-cooling component adopts a spiral tube 11 structure, which achieves heat exchange in the following way: the spiral tube 11 is wound inside the separation chamber 5, and cooling water flows in from the inlet pipe and flows along the spiral path to exchange heat with the silicon carbide vapor in the separation chamber 5. After absorbing heat, it flows out from the outlet pipe. The spiral shape increases the heat exchange area, prolongs the contact time between the cooling water and the vapor, and improves the liquefaction efficiency. The spiral tube 11 design significantly improves the heat exchange efficiency of the water-cooling component and ensures that the water vapor is fully liquefied. The spiral tube 11 layout makes reasonable use of the internal space of the separation chamber 5 and reduces the size of the equipment.

[0029] The inlet pipe is fixedly connected to one end of the separation chamber 5, and the outlet pipe is fixedly connected to the other end of the separation chamber 5. The inlet 7 of the inlet pipe is located outside the separation chamber 5, and the outlet of the outlet pipe is located outside the separation chamber 5.

[0030] In this embodiment, the inlet pipe and the outlet pipe are fixed at both ends of the separation chamber 5, and both the inlet and outlet are located outside the chamber, forming an independent cooling water circulation system. The inlet pipe is connected to the spiral tube 11 from one end of the separation chamber 5 to introduce low-temperature cooling water; the outlet pipe discharges the cooled water after heat absorption from the other end, and the external water source or cooling equipment is connected to achieve circulation. The water pipe interface is external, which is convenient for connecting to an external cooling system and daily maintenance.

[0031] The centrifugal assembly includes a rotating shaft 13 and fan blades 14. The two ends of the rotating shaft 13 are rotatably connected to the center of the separation chamber 5. A plurality of fan blades 14 are fixedly arranged on the rotating shaft 13. The spiral tube 11 surrounds the fan blades 14 and the rotating shaft 13. One end of the rotating shaft 13 is fixedly connected to the output shaft of the motor 10. The motor 10 is fixed inside the motor cavity 8, and the motor cavity 8 is fixed at one end of the separation chamber 5.

[0032] In this embodiment, the centrifugal assembly drives the rotating shaft 13 and fan blades 14 to rotate via the motor 10, generating a centrifugal force field. When the fan blades 14 rotate, the liquefied water droplets, due to their large mass, are thrown towards the inner wall of the separation chamber 5 under the action of centrifugal force. The spiral tube 11 surrounds the fan blades 14 and the rotating shaft 13, without affecting the transmission of centrifugal force. At the same time, it works in conjunction with the centrifugal assembly (water vapor is first liquefied by water cooling and then separated by centrifugation). The centrifugal force accelerates the separation of liquid water and gas, preventing water droplets from being carried out of the discharge pipe 4 with the gas, thus enhancing the "anti-entrainment" effect.

[0033] It also includes a filter assembly, the discharge pipe 4 is connected to the filter assembly, and the filter assembly is used for secondary filtration of water in the silicon carbide gas.

[0034] In this embodiment, a filter assembly is added after the discharge pipe 4 to perform secondary treatment on the silicon carbide gas through physical adsorption or interception. When the gas flows through the filter assembly, the residual trace moisture is adsorbed by the filter material, further reducing the gas humidity. The secondary filtration ensures the dryness of the discharged gas, forming a multi-stage treatment with water cooling and centrifugal separation.

[0035] The filter assembly includes a base 12, the center of which is fixedly connected to the discharge pipe 4. The base 12 is screwed to a filter element placement groove 3, and the upper end of the filter element placement groove 3 is fixedly provided with a discharge port 2. The water-absorbing block can be placed in the placement area formed by the filter element placement groove 3 and the base 12.

[0036] In this embodiment, the filter assembly adopts a detachable structure. The base 12 is screwed to the filter element placement groove 3 to form a closed placement area, which is filled with water-absorbing blocks (such as activated carbon, molecular sieves, etc.). Gas enters from the discharge pipe 4 in the center of the base 12. When passing through the water-absorbing blocks, the moisture is adsorbed, and the dry gas is discharged from the discharge port 2 at the upper end of the filter element placement groove 3. The screwed structure makes it easy to disassemble the filter element placement groove 3 and replace the water-absorbing blocks, reducing maintenance costs. The screwed connection ensures the sealing of the filter assembly and prevents the leakage of unfiltered gas.

[0037] A sensor 1 is installed on the base 12. The sensor 1 is a humidity sensor 1, and the contact of the sensor 1 is located inside the base 12.

[0038] In this embodiment, a humidity sensor 1 is installed on the base 12, with its contacts extending into the base 12 to monitor the humidity of the absorbent block in real time. The sensor 1 senses the water content of the absorbent block and converts the humidity signal into an electrical signal to dynamically monitor the working status of the filter component and prevent the absorbent block from failing after it becomes saturated.

[0039] It also includes a controller, which transmits data with sensor 1. Sensor 1 monitors the humidity of the water-absorbing block in the base 12 and filter placement slot 3 in real time. When the humidity is greater than the set threshold, the controller controls the alarm to sound an alarm. The alarm is installed on the separation chamber 5 and the controller is electrically connected to the alarm.

[0040] In this embodiment, the warning device adopts an existing product of the prior art, which is not shown in the figure and will not be described in detail. An automated monitoring system is formed by the controller, sensor 1 and the warning device. Sensor 1 transmits humidity data to the controller, and the controller presets a humidity threshold. When the humidity exceeds the threshold, the controller triggers the warning device (such as an audible and visual alarm) to prompt the user to replace the water-absorbing block, automatically warns of the failure risk of the filter component, improves the operating efficiency of the equipment, and avoids the gas moisture content exceeding the standard due to the saturation of the water-absorbing block.

[0041] It also includes a connecting seat 15, which is fixed by the separation cavity 5 and facilitates the installation of the separation cavity 5.

[0042] In this embodiment, the separation chamber 5 is fixed by the connecting seat 15, which provides an installation interface (such as bolt holes, flanges, etc.) to realize the mechanical connection between the equipment and other systems. The connecting seat 15 is adaptable to different installation scenarios, making it easy to integrate the equipment into the production line.

[0043] The method of using this utility model is as follows:

[0044] The separation chamber 5 is fixed in a suitable position by connecting the connector 15. According to the actual installation scenario, the equipment is mechanically connected to other systems by using the bolt holes, flanges and other interfaces on the connector 15 to complete the installation of the equipment. The inlet pipe is connected to the external cooling water source, and the outlet pipe is connected to the cooling equipment or drainage system. The cooling water source is turned on, so that the low temperature cooling water flows from the inlet pipe into the spiral pipe 11 and flows along the spiral path to exchange heat with the silicon carbide gas in the separation chamber 5. After absorbing heat, it flows out from the outlet pipe to form a cooling water circulation system, which cools down the silicon carbide gas and liquefies the water vapor in it into liquid water.

[0045] When the motor 10 is turned on, the motor 10 drives the rotating shaft 13 and the fan blade 14 to rotate, generating a centrifugal force field. When the fan blade 14 rotates, the liquefied water droplets are thrown towards the inner wall of the separation chamber 5 under the action of centrifugal force. The liquid water gathers along the wall and is discharged through the drain pump 9, while the dry silicon carbide gas flows out from the discharge pipe 4.

[0046] Silicon carbide gas enters the base 12 of the filter assembly from the discharge pipe 4. The water is adsorbed by the water-absorbing blocks (such as activated carbon, molecular sieves, etc.) filled in the placement area formed by the filter element placement groove 3 and the base 12. The dry gas is discharged from the discharge port 2 at the top of the filter element placement groove 3, thus completing the secondary filtration.

[0047] Humidity sensor 1 monitors the humidity of the water-absorbing block inside the base 12 in real time and converts the humidity signal into an electrical signal and transmits it to the controller. When the humidity exceeds the set threshold, the controller controls the alarm installed on the separation chamber 5 to sound an alarm, prompting the user to remove the filter element placement slot 3 and replace the water-absorbing block to ensure that the filter assembly works normally.

[0048] Through a multi-stage treatment mechanism of water-cooled liquefaction, centrifugal separation and filtration, and through components such as spiral tube 11, centrifugal assembly, filtration assembly and intelligent monitoring (sensor 1, alarm system), efficient separation and anti-entrainment of silicon carbide gas are achieved.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
