Description

Technical Field

[0001] The invention relates to the technical field of sulfur hexafluoride gas filtering, in particular to a sulfur hexafluoride gas purification and filtering device. Background Art

[0002] Sulfur hexafluoride gas is a colorless, odorless, non-toxic, non-flammable, transparent gas. It is an inert gas at room temperature and generally does not react with other materials. Pure sulfur hexafluoride gas is generally non-toxic and has excellent insulation and arc extinguishing properties. In recent decades, sulfur hexafluoride gas has been widely used in high-voltage electrical appliances, including high-voltage circuit breakers at all levels and some gas transformers. After long-term use of sulfur hexafluoride gas, a certain amount of moisture and dust will be mixed in. When the impurities in sulfur hexafluoride gas exceed the standard, the equipment must be shut down for maintenance and the sulfur hexafluoride gas must be recovered and filtered. The filtration of sulfur hexafluoride gas is mostly handled by filter tanks.

[0003] The above device does not have the structure of gas transmission buffering, rapid filtration and moisture separation when in use, so that most of the existing gas filter tanks can only perform a single purification treatment on the gas when in use. Since the external pipeline is directly connected to the joint on the tank body, after the high-speed gas directly enters the tank body, the high-speed flowing gas continuously impacts the inner wall of the tank body. The tank body is easily damaged by the impact for a long time and gas leakage occurs. At the same time, the gas cannot maintain a relatively stable flow rate when it is sent into the tank body. If the gas flow rate increases rapidly in a short period of time and does not decrease for a long time, the pressure in the tank body will increase rapidly and cause damage. Moreover, after the sulfur hexafluoride gas is filtered by the filter tank, it still needs to be transferred to other equipment for moisture separation, which is relatively cumbersome and inefficient, and is not convenient to use. Based on the deficiencies in the existing technology, the present invention designs a sulfur hexafluoride gas purification and filtering device. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The sulfur hexafluoride gas purification and filtering device, after the gas is input into the air inlet pipe, it will first enter the interior of the bellows, and will be distributed to two counter-flow air ducts through the diverter block. When the gas flows out from the counter-flow air duct through the air outlet plate, it will be counter-flowed to slow down the gas and quickly fill the entire cavity above the mesh plate, thereby preventing the high-speed gas from impacting the same point in the tank for a long time. At the same time, if the gas input speed is too fast, the gas passing through the air outlet plate will push the windshield to move to one side and compress the spring through the movable shaft. Since the movable shaft is provided with an adjusting arc groove and connected to the rotating gear, When the movable shaft moves to one side, the adjusting arc groove also moves accordingly to control the movement of the rotating teeth. Since the rotating teeth are fixed on the swivel, and the swivel is connected to the limiting shaft through the limiting arc groove, when the rotating teeth are affected by the adjusting arc groove and move, the swivel will rotate under the restriction of the limiting arc groove and the limiting shaft and drive the blocking hole arc plate to rotate accordingly, and the orifice plate at a specific position on the air outlet plate is closed to reduce the intake volume and alleviate the gas input speed, thereby achieving buffering and deceleration of the gas before entering the gas filter tank. This device is convenient for preventing the airflow from impacting the inner wall of the tank for a long time to cause damage and the airflow velocity from suddenly increasing to cause damage due to excessive internal pressure.

[0018] 2. The sulfur hexafluoride gas purification and filtering device connects the gas input pipe and the output pipe to the buffer mechanism and the exhaust pipe respectively. The input pipe sends the gas into the gas filter tank and then passes through the mesh plate to reach the chamber between the mesh plate and the partition plate. At this time, the gas passes through the filter element into the air inlet pipe and enters the chamber below the partition plate through the connecting pipe and the through hole to be discharged. The heavier impurities in the gas directly fall on the partition plate for collection, while the lighter impurities are intercepted by the filter element as the gas flows and adsorbed on its surface to achieve gas purification. The device is convenient for filtering sulfur hexafluoride gas.

[0019] 3. The sulfur hexafluoride gas purification and filtering device allows the purified gas to pass through the partition plate into the lower chamber, and starts the driving motor to drive the rotating shaft and the wind wheel to rotate through the reducer to blow the gas in the chamber into the dewatering box. At the same time, the external device of the output pipe starts to extract gas. At this time, the purified gas in the gas filter tank begins to pass through the dewatering box and flow into the inside of the exhaust pipe. Since flexible sealing strips are provided between multiple sets of fixed arc plates and movable arc plates, the gas can only pass between the fixed arc plates and the movable arc plates. When the gas flows through, the high-speed rotating wind wheel will drive The gas rotates in the fixed arc plate and the movable arc plate, and the water vapor contained in the gas is centrifugally thrown to the inner wall of the fixed arc plate and the movable arc plate to slide down. If the current speed cannot meet the dehydration rate, it is only necessary to start the servo motor to drive the threaded adjustment rod to rotate and control the movable block to drive the movable arc plate to move back and forth and adjust the staggered distance between the movable arc plate and the fixed arc plate to assist in increasing the centrifugal rotation time and improving the dehydration effect. The separated water slides from the fixed arc plate and the movable arc plate, passes through the leakage groove and the ceramic permeable plate, and falls to the bottom of the gas filter tank for collection. This device is convenient for separating the water vapor contained in the purified gas.

[0020] 4. A sulfur hexafluoride gas purification and filtering device, in which gas enters the wind box from the air inlet pipe to impact the diverter block. After the diverter block is impacted, it moves backward and pushes the first push rod to move inward. When the first push rod moves, it pushes the second push rod to move accordingly and stretches the traction spring. At this time, the second push rod continues to move inward under the push of the diverter block. Since the second push rod is inserted into the inside of the inclined groove, the second push rod will push the locking orifice plate to rotate under the limit of the inclined groove when it moves, so that the holes of the mesh plate are aligned with the holes of the locking orifice plate. At this time, the upper and lower spaces of the mesh plate in the gas filter tank can be connected for gas purification. If the equipment is shut down, the diverter block is not pushed by the traction spring to retract and the traction spring and the second push rod move in the opposite direction and reset, and the locking orifice plate rotates in the opposite direction under the control of the second push rod and the second push rod, so that the holes of the locking orifice plate and the mesh plate are staggered to separate the upper and lower spaces of the mesh plate, thereby preventing the purified gas from flowing back. The device is convenient for quickly opening and closing the gas filter tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] A sealing top plate 207 is provided to facilitate sealing of the top of the gas filter tank 1. A limiting cylinder 203, a threaded handle 204 and a threaded lifting rod 205 are provided, and a connecting frame 206 and a sealing top plate 207 are connected to the bottom of the threaded lifting rod 205. The threaded handle 204 is rotated to push the threaded lifting rod 205 upward with the support of the limiting cylinder 203 to pull the sealing top plate 207 up and down to achieve cleaning and maintenance of the gas filter tank 1.

[0046] Working principle: when a sulfur hexafluoride gas purification and filtering device is used, in the initial state, the top of the gas filter tank 1 is first connected and sealed with the sealing top plate 207 through the top plate 102, and a buffer mechanism 5 and an exhaust pipe 101 are arranged on the gas filter tank 1 to facilitate the circulation of gas. At the same time, a through hole 302 is opened on the partition plate 301 arranged in the gas filter tank 1, and a connecting pipe 303 on the through hole 302 is connected to the air inlet pipe 305, and a filter element 307 is sleeved on the outer side of the air inlet pipe 305, so as to filter the circulating gas. The air inlet 303 arranged above the filter mechanism 3 The inner end of the tube 501 is connected to a bellows 502, and both sides of the bellows 502 are provided with counter-winding ducts 503, and the gas outlet ends of the counter-winding ducts 503 are arranged facing each other, so as to achieve the deceleration of high-speed gas by counter-winding, and the water removal box 401 arranged below the filter mechanism 3 is provided with an air inlet 402 on one side, and the other side is connected to the exhaust pipe 101, and the fixed arc plate 408 and the movable arc plate 409 arranged in the partition plate 301 are staggered, and at the same time, the fixed arc plate 408 and the movable arc plate 409 are provided with wind wheels 418 driven by a driving motor 416, so as to separate the water in the gas by centrifugation;

[0047] When it is necessary to prevent high-speed gas from entering the gas filter tank 1 and damaging the tank body, the gas is first input into the air inlet pipe 501 and then enters the interior of the bellows 502, and is distributed to the two counter-flow air pipes 503 through the diverter block 504. When the gas flows out from the counter-flow air pipe 503 through the air outlet plate 505, it will be countered to slow down the gas and quickly fill the entire cavity above the mesh plate 105. If the gas input speed is too fast, the gas passing through the air outlet plate 505 will push the wind shield 512 to move to one side and compress the spring 509 through the movable shaft 508. Since the movable shaft 508 is provided with an adjusting The arc groove 511 is connected to the rotating tooth 516, so that when the movable shaft 508 moves to one side, the adjusting arc groove 511 also moves to control the movement of the rotating tooth 516. Since the rotating tooth 516 is fixed on the rotating ring 514, and the rotating ring 514 is connected to the limiting shaft 513 through the limiting arc groove 515, when the rotating tooth 516 moves under the influence of the adjusting arc groove 511, the rotating ring 514 will rotate under the restriction of the limiting arc groove 515 and the limiting shaft 513, and drive the hole blocking arc plate 517 to rotate accordingly to close the specific position of the hole plate on the air outlet hole plate 505 to reduce the intake amount and alleviate the input speed of the gas.

[0048] When it is necessary to filter the sulfur hexafluoride gas, firstly, the gas input pipe and the output pipe are connected to the buffer mechanism 5 and the exhaust pipe 101 respectively. The input pipe sends the gas into the gas filter tank 1 and then passes through the mesh plate 105 to reach the chamber between the mesh plate 105 and the partition plate 301. At this time, the gas passes through the filter element 307 into the air inlet pipe 305 and enters the chamber below the partition plate 301 through the connecting pipe 303 and the through hole 302 to be discharged. The heavier impurities in the gas directly fall on the partition plate 301 for collection, while the lighter impurities are intercepted by the filter element 307 as the gas flows and adsorbed on its surface to achieve gas purification. The device is convenient for filtering sulfur hexafluoride gas.

[0049] When it is necessary to separate the water vapor contained in the purified gas, the purified gas first passes through the partition plate 301 into the lower chamber, and the drive motor 416 is started to drive the rotating shaft 417 and the wind wheel 418 to rotate through the reducer 415 to blow the gas in the chamber into the dewatering box 401. At the same time, the external equipment of the output pipe starts to extract gas. At this time, the purified gas in the gas filter tank 1 begins to pass through the dewatering box 401 and flow into the exhaust pipe 101. Since a flexible sealing strip 410 is provided between the multiple sets of fixed arc plates 408 and the movable arc plates 409, the gas can only pass between the fixed arc plates 408 and the movable arc plates 409. When the gas flows through, the high-speed rotating wind wheel 418 will drive the gas The body rotates inside the fixed arc plate 408 and the movable arc plate 409 and centrifugally throws the water vapor contained in the gas to the inner wall of the fixed arc plate 408 and the movable arc plate 409 to slide down. If the current speed cannot meet the dehydration rate, it is only necessary to start the servo motor 414 to drive the threaded adjustment rod 413 to rotate and control the movable block 411 to drive the movable arc plate 409 to move back and forth and adjust the staggered distance between the movable arc plate 409 and the fixed arc plate 408 to assist in increasing the centrifugal rotation time and improving the dehydration effect. The separated water slides from the fixed arc plate 408 and the movable arc plate 409, passes through the leakage groove 406 and the ceramic permeable plate 407, and falls on the bottom of the gas filter tank 1 for collection. The device is convenient for separating the water vapor contained in the purified gas.

[0050] When the gas filter tank 1 needs to be opened and closed quickly, the gas first enters the wind box 502 from the air inlet pipe 501 to impact the diverter block 504. After the diverter block 504 is impacted, it moves backward and pushes the first push rod 603 to move inward. When the first push rod 603 moves, it pushes the second push rod 605 to move and stretch the traction spring 604. At this time, the second push rod 605 continues to move inward under the push of the diverter block 504. Since the second push rod 605 is inserted into the inside of the inclined groove 606, when the second push rod 605 moves, it will push the locking hole plate 602 to rotate under the limit of the inclined groove 606 , so that the holes of the mesh plate 105 are aligned with the holes of the locking hole plate 602. At this time, the upper and lower spaces of the mesh plate 105 in the gas filter tank 1 can be connected for gas purification. If the equipment is shut down, the diverter block 504 is not pushed by the traction spring 604, the traction spring 604 and the second push rod 605 move in the opposite direction and reset, and the locking hole plate 602 rotates in the opposite direction under the control of the second push rod 605 and the second push rod 605 so that the holes of the locking hole plate 602 and the mesh plate 105 are staggered to separate the upper and lower spaces of the mesh plate 105, thereby preventing the purified gas from flowing back. The device is convenient for quickly opening and closing the gas filter tank 1.
