[0002] A cyclone tower is a separation device that separates particulate impurities in exhaust gas through the cyclone effect of exhaust gas. It has the advantages of high efficiency, energy saving, and low operating cost. It is widely used in chemical, metallurgical and other industries. When the existing cyclone tower separates and purifies the exhaust gas, it cannot perform targeted separation and purification of the exhaust gas according to the impurity content in the exhaust gas.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0019] Example 1 like Figure 3-Figure 7As shown, an industrial waste gas multi-effect purification device includes a cyclone tower 1, a cyclone pot 2, a demister 3 and a fixing ring 4; a liquid storage part 1001 is arranged at the lower part of the cyclone tower 1; an air outlet 1002 is arranged at the upper part of the cyclone tower 1; the air outlet 1002 is communicated with an external air pump; a cyclone pot 2 is arranged on the cyclone tower 1; the cyclone pot 2 is located above the liquid storage part 1001; an air inlet 2001 is arranged at the front right part of the cyclone pot 2; a demister 3 is installed at the upper inner part of the cyclone tower 1; two fixing rings 4 are arranged inside the cyclone pot 2; It also includes a spray assembly, a fixture 5, a swirl plate 6, a support pipe 7, a transmission assembly and a cleaning system; a spray assembly is installed on the swirl tower 1; a support pipe 7 is installed on the spray assembly; a transmission chamber 7001 is opened inside the support pipe 7; two liquid storage chambers 7002 are opened inside the support pipe 7; a plurality of liquid outlets 7003 in a ring array are opened on the outside of the liquid storage chamber 7002; two fixtures 5 are arranged on the support pipe 7 for lifting; each fixture 5 is located on the outside of the adjacent liquid storage chamber 7002; a plurality of swirl plates 6 in a ring array are movably arranged on the outside of the fixture 5; the upper part of the swirl plate 6 and the fixing ring 4 are softly connected; a transmission assembly is installed on the outside of the support pipe 7; a cleaning system is installed on the swirl plate 6; the middle parts of the plurality of swirl plates 6 are driven to rise and fall by the fixture 5, and the gap between the two adjacent swirl plates 6 is adjusted, which is beneficial to control the amount of exhaust gas passing between the two adjacent swirl plates 6 and enhance the exhaust gas treatment effect.

[0020] The spray assembly includes a pump 101, a transmission pipe 102, a spray pipe 103 and a nozzle 104; the pump 101 is fixedly connected to the cyclone tower 1; the pump 101 is connected to the liquid storage part 1001 on the cyclone tower 1; the transmission pipe 102 is fixedly connected to the pump 101; the transmission pipe 102 is connected to the transmission cavity 7001 in the support pipe 7; two spray pipes 103 are connected to the transmission pipe 102; each spray pipe 103 is located inside the cyclone tank 2; each spray pipe 103 is located above the corresponding fixing ring 4; and a number of nozzles 104 are fixedly connected to each spray pipe 103.

[0021] The transmission component includes a transmitter 201 and a connecting tube 202; two transmitters 201 are fixedly connected to the outside of the support tube 7; the upper and lower sides of each transmitter 201 are connected to four connecting tubes 202 in a ring array; the connecting tube 202 on the upper side of each transmitter 201 is connected to the transmission cavity 7001 in the support tube 7; the connecting tube 202 on the lower side of each transmitter 201 is connected to the adjacent liquid storage cavity 7002 in the support tube 7.

[0022] Each nozzle 104 located between the two fixed rings 4 is inclined in the opposite direction of the exhaust gas rotation direction, so that the rotating exhaust gas and the cyclone generated by the nozzle 104 spraying are offset, thereby improving the emulsification effect of the exhaust gas and water and enhancing the exhaust gas treatment effect; each nozzle 104 located above the fixed ring 4 is inclined in the exhaust gas rotation direction; this is beneficial to enhancing the centrifugal force of the exhaust gas during rotation, improving the wall hanging effect of the emulsified impurities in the exhaust gas, and enhancing the exhaust gas treatment efficiency.

[0023] The liquid outlet 7003 of each support tube 7 is inclined along the direction of exhaust gas rotation; each liquid outlet 7003 is configured to have a constricted structure; this is beneficial to increasing the pressure when water is sprayed out from the liquid outlet 7003, ensuring the centrifugal force when the exhaust gas rotates, and preventing the emulsification effect of the exhaust gas and water from being reduced.

[0024] The fixture 5 is provided with a plurality of liquid spraying ports 5001 in a circular array; and each liquid spraying port 5001 is provided with a constricted structure; the liquid spraying port 5001 with a constricted structure enhances the pressure of the water flow when it is sprayed out, flushes the surface of the swirl plate 6, reduces the adhesion of sticky impurities on the surface of the swirl plate 6, and facilitates the subsequent cleaning of the device.

[0025] It also includes a driving member 105; two driving members 105 are fixedly connected inside the support tube 7, and the driving member 105 is an electric push rod; the telescopic end of each driving member 105 is fixedly connected to the adjacent fixer 5; each driving member 105 is located in the middle of the adjacent transmitter 201.

[0026] The waste gas treatment process of the present invention is as follows: When purifying the waste gas, the pump 101 is controlled to extract the water in the liquid storage part 1001, and transmits it to the two spray pipes 103 through the transmission pipe 102, and then the nozzle 104 sprays it in the swirl pot 2. At this time, the waste gas is pumped into the swirl pot 2 from the air inlet 2001 by the external air pump. The waste gas in the swirl pot 2 moves upward and contacts the swirl plate 6. The waste gas is guided by the inclined swirl plate 6 to form a cyclone. The waste gas contacts the sprayed water during the rotation process, and the water is emulsified with the particulate impurities in the waste gas, thereby absorbing the particulate impurities in the waste gas and purifying the waste gas. In this process, since each nozzle 104 between the two fixed rings 4 is inclined in the opposite direction of the exhaust gas rotation direction, the rotating exhaust gas and The cyclone generated when the nozzle 104 sprays is counteracted to improve the emulsification effect of the exhaust gas and water, and enhance the treatment effect of the exhaust gas. Each nozzle 104 located above the fixed ring 4 is inclined along the rotation direction of the exhaust gas, which is beneficial to enhance the centrifugal force of the exhaust gas during rotation, so that the impurities separated from the exhaust gas can fully adhere to the inner wall of the cyclone tank 2, improve the wall hanging effect of the impurities in the exhaust gas, and enhance the treatment efficiency of the exhaust gas. The purified exhaust gas continues to rise and contacts the demister 3, and the water vapor in the gas is removed by the demister 3. Then the gas enters the next purification process through the gas outlet 1002, and the impurities separated from the exhaust gas flow downward along the inner wall of the cyclone tank 2 into the liquid storage part 1001, and the impurities are filtered by the filtering device in the liquid storage part 1001, so that the water is recycled.

[0027] When the impurity content in the exhaust gas is high, the water flow in the transmission pipe 102 enters the transmission cavity 7001, and then flows into each transmission device 201 and each liquid storage cavity 7002 through the connecting pipe 202. At this time, the control driving member 105 extends to push the fixture 5 downward, so that the fixture 5 drives the middle part of several swirl plates 6 to descend, thereby rotating the swirl plates 6, expanding the gap between two adjacent swirl plates 6, and increasing the amount of exhaust gas passing between each swirl plate 6. When the liquid outlet 7003 is higher than the upper surface of the fixture 5, the water in the liquid storage cavity 7002 is sprayed out from the liquid outlet 7003. Since each liquid outlet 7003 is inclined along the direction of exhaust gas rotation, and each liquid outlet 7003 is configured to have a shrinking structure, the water in the liquid storage cavity 7002 is sprayed out from the liquid outlet 7003. The sprayed water flow drives the air flow to form a cyclone, and at the same time increases the pressure when the water is sprayed from the liquid outlet 7003, ensuring the centrifugal force when the exhaust gas rotates, preventing the gap between the swirl plates 6 from expanding and reducing the guiding effect of the exhaust gas, avoiding the reduction of the residence time of the exhaust gas in the swirl tank 2, resulting in insufficient contact between the exhaust gas and the sprayed water, thereby avoiding the reduction of the emulsification effect of the exhaust gas and the water, improving the exhaust gas treatment efficiency, and enhancing the purification effect of the exhaust gas. During the descending process of the fixture 5, the liquid outlet 7003 is connected with the liquid spray port 5001, and the pressure of the water flow when spraying is increased through the liquid spray port 5001 with a contracted structure, so as to rinse the surface of the swirl plate 6, reduce the adhesion of sticky impurities on the surface of the swirl plate 6, and facilitate the subsequent cleaning of the device.

[0028] When the impurity content in the exhaust gas is low, the control driving member 105 is contracted to lift the holder 5 upward, so that the holder 5 drives the middle parts of several cyclone plates 6 to rise, thereby rotating the cyclone plates 6, narrowing the gap between two adjacent cyclone plates 6, reducing the amount of exhaust gas passing between two adjacent cyclone plates 6, extending the residence time of the exhaust gas in the cyclone tank 2, fully removing impurities in the exhaust gas, and enhancing the exhaust gas treatment effect.

[0029] Example 2 On the basis of Example 1, Figure 7-Figure 10 As shown, the cleaning system includes a lower scraper 301 and an upper scraper 302; each swirl plate 6 is fixedly connected to a lower scraper 301; each swirl plate 6 is fixedly connected to an upper scraper 302; the sticky impurities adhering to the surface of the swirl plate 6 are scraped and collected by the lower scraper 301 and the upper scraper 302, so as to prevent the sticky impurities from accumulating on the surface of the swirl plate 6, and to avoid the adhesion of sticky impurities between two adjacent swirl plates 6, resulting in the inability to adjust the exhaust gas flow rate, thereby ensuring the exhaust gas treatment effect and facilitating the subsequent cleaning of the device.

[0030] The width of each lower scraper blade 301 is greater than that of the adjacent upper scraper blade 302; the liquid spray port 5001 on each fixture 5 is inclined toward the lower scraper blade 301; the sticky impurities on the upper scraper blade 302 are scraped off by the lower scraper blade 301 for centralized collection, so that the sticky impurities are all located on the upper surface of the lower scraper blade 301, preventing the water pressure sprayed from the liquid spray port 5001 from being insufficient to flush and clean the lower scraper blade 301 and the upper scraper blade 302 at the same time, thereby improving the cleaning effect of the swirl plate 6.

[0031] The cleaning system also includes a guide plate 303; each swirl plate 6 is fixedly connected to a guide plate 303 on its upper surface; each guide plate 303 is curved downward on the side away from the lower scraper blade 301; all guide plates 303 are located on the outside of all lower scrapers 301; the guide plates 303 guide the viscous impurities flushed from the upper surface of the lower scraper blade 301 downward into the liquid storage portion 1001 to prevent the viscous impurities from being flushed and adhering to the swirl plate 6, thereby facilitating subsequent cleaning of the device.

[0032] The specific cleaning process of the present invention is as follows: When sticky impurities continue to adhere to and accumulate on the surface of the swirl plate 6, the control driving member 105 is contracted to lift the holder 5 upward, so that the holder 5 drives the middle parts of several swirl plates 6 to rise, and then the swirl plate 6 drives the lower scraper 301 and the upper scraper 302 to approach the two adjacent swirl plates 6, and the sticky impurities accumulated on the lower surface of the adjacent swirl plate 6 are scraped and collected by the lower scraper 301, and the sticky impurities accumulated on the upper surface of the other swirl plate 6 are scraped and collected by the upper scraper 302. When the impurities on the surface of the swirl plate 6 are scraped onto the lower scraper 301 and the upper scraper 302, since the width of the lower scraper 301 is greater than that of the upper scraper 302, the sticky impurities on the upper scraper 302 are scraped off by the lower scraper 301 for centralized collection, so that the sticky impurities are all located at the lower scraper The upper surface of the scraper 301 is prevented from having insufficient water pressure from the water flow sprayed from the liquid spray port 5001 to simultaneously flush and clean the lower scraper 301 and the upper scraper 302, thereby improving the cleaning effect of the swirl plate 6. Subsequently, the control driving member 105 is extended to push the holder 5 downward to rotate the swirl plate 6, thereby separating the lower scraper 301 and the upper scraper 302. At this time, the liquid spray port 5001 is opened, and the sticky impurities on the upper surface of the lower scraper 301 are flushed toward the guide plate 303 through the liquid spray port 5001 inclined toward the lower scraper 301. The sticky impurities flushed from the upper surface of the lower scraper 301 are guided downward into the liquid storage portion 1001 through the curved guide plate 303, preventing the sticky impurities from being flushed and adhering to the swirl plate 6, thereby facilitating the subsequent cleaning of the device.

[0033] Example 3 On the basis of Example 1, Figure 1 , Figure 2 , Fig.11 and Fig.12As shown, a wall scraping system is also included, which includes a scraping rod 401, a support ring 402 and a ball 403; the support tube 7 is rotatably connected to the transmission tube 102; four scraping rods 401 in a circular array are fixedly connected to the upper side of each fixed ring 4; each scraping rod 401 is inclined in the opposite direction of the exhaust gas rotation direction; each scraping rod 401 is in contact with the inner wall of the swirl pot 2; two support rings 402 are fixedly connected to the inside of the swirl pot 2; each support ring 402 is located at the lower side of the adjacent fixed ring 4; each support ring 402 has a movable upper side A plurality of balls 403 in a circular array are provided; when the exhaust gas passes through the swirl plate 6, the exhaust gas drives the fixed ring 4 to rotate on the support ring 402, and then drives the scraper rod 401 to rotate, and the impurities adhered to the inner wall of the swirl tank 2 are scraped downward by the scraper rod 401, while ensuring the rotation of the exhaust gas, it is convenient for the subsequent cleaning of the device, while the fixed ring 4 rotates on the support ring 402, the friction between the fixed ring 4 and the support ring 402 is reduced by the balls 403, which is conducive to the rotation of the fixed ring 4 on the support ring 402.
