Background technique

In the process of industrial production, the combustion of some fossil fuels will produce a large amount of dust, which will pollute the environment if it is directly discharged into the air. Therefore, it is necessary to use dust removal equipment such as bag filter and electrostatic precipitator to remove dust from the dusty gas, but When dealing with some high-temperature gases, the efficiency of the bag filter will decrease, and the cost of the electrostatic precipitator is relatively high, while the ceramic membrane filter is widely used due to its high temperature resistance, low cost, and long service life.

The purpose of blowing cleaning work, but the technical problem of increasing the frequency of back blowing cleaning work.

But also there is following problem in this device:

1. The air inlet of the device is circular, and the silicon carbide ceramic membrane cannot rotate during the process of treating waste gas. When the dusty gas blown out from the air inlet contacts the silicon carbide ceramic membrane, it will affect the Continuous impact on one side causes only a certain part of the silicon carbide ceramic membrane to remove dust, and the rest basically does not participate in dust removal, so the full dust removal effect of the silicon carbide ceramic membrane cannot be exerted.

2. The device helps discharge the dust above the lifting plate by setting a material guide slope on the top of the lifting plate, but there will still be a small amount of dust attached to the surface of the lifting plate, and the dust on the surface of the lifting plate needs to be cleaned up later.

3. After the bristles of the device clean the dust on the outside of the silicon carbide ceramic membrane, some dust will adhere to the bristles, which reduces the subsequent cleaning effect on the silicon carbide ceramic membrane.

When it is necessary to use this separator to remove dust from the dusty gas, the operator passes the dusty gas into the air inlet 202, and the filter screen of the air inlet 202 intercepts the large particles of impurities in the dusty gas, and dedusts the dusty gas. Primary filtration to achieve primary separation of dusty gas and large particle impurities. Subsequently, the dust-containing gas enters the arc-shaped cavity 203 and disperses. The operator starts the servo motor 5 through the control terminal. The servo motor 5 drives the rotating sleeve 3 to rotate through the second gear 6 and the first gear 4, and the rotating sleeve 3 drives The three separation sleeves 7 and the rectangular housing 9 and the parts on them rotate. Taking the counterclockwise rotation of the rectangular housing 9 as an example, the rectangular housing 9 drives the T-shaped baffle 1203 to rotate counterclockwise. In the initial state, the T-shaped baffle The plate 1203 is in contact with the left half of the inner wall of the fixed housing 2, and the extension spring 1204 is in a stretched state. The T-shaped baffle 1203 is sealed with the side of the rectangular housing 9 close to the separation sleeve 7. When the T-shaped baffle 1203 turns to When the front side of the arc-shaped cavity 203 is reached, the arc-shaped surface of the T-shaped baffle 1203 is in contact with the front side reducing diameter of the inner surface of the fixed housing 2, and the extension spring 1204 is reset, and the extension spring 1204 drives the T-shaped baffle 1203 away from the separation. The sleeve 7, the seal between the T-shaped baffle 1203 and the rectangular housing 9 is released, the arc-shaped surface of the T-shaped baffle 1203 penetrates into the arc-shaped cavity 203, and the arc-shaped surface of the T-shaped baffle 1203 and the fixed shell The right half of the inner wall of the body 2 is in contact, the tension spring 1204 is no longer in a stretched state, and the dust-containing gas in the arc-shaped cavity 203 enters the separation sleeve 7 through the gap between the T-shaped baffle plate 1203 and the rectangular housing 9, The dust-containing gas entering the separation sleeve 7 impacts the outer surface of the silicon carbide ceramic membrane 11, and the dust in the dust-containing gas is intercepted by the silicon carbide ceramic membrane 11 and adheres to the outer surface thereof.

Since the silicon carbide ceramic membrane 11, the rectangular housing 9, and the air inlet 202 are aligned and have equal longitudinal lengths, the dust-containing gas sprayed on the silicon carbide ceramic membrane 11 is dispersed in strips, and then rotates through the silicon carbide ceramic membrane 11. , so that the dust-containing gas blown out from the rectangular housing 9 is evenly distributed on the silicon carbide ceramic membrane 11 . In the initial state, the electromagnetic valve in the storage sleeve 8 is in a closed state, and the dust-laden gas between the separation sleeve 7 and the silicon carbide ceramic film 11 will not be transported downward. The dusty gas filtered by the ceramic membrane 11 will not pass downwards. Therefore, the dusty gas (clean) filtered by the silicon carbide ceramic membrane 11 is transported upwards through the gap between the blocking plate and the silicon carbide ceramic membrane 11 into the bellows 1503, and enters the exhaust cavity 301 through the bellows 1503, The gas in the exhaust cavity 301 is exhausted through the through hole of the rotating sleeve 3 and the exhaust hole 201 .

During the counterclockwise rotation of the rotating sleeve 3, the rotating sleeve 3 drives the third gear 1304 to rotate through the rotating rod 1301. Mesh, with the rotating rod 1301 turning counterclockwise, the third gear 1304 starts to rotate, the third gear 1304 drives the fan blade 1306 to rotate through the rotating rod 1301, and the fan blade 1306 pumps the gas in the silicon carbide ceramic membrane 11 upwards, and the silicon carbide ceramic The air pressure in the membrane 11 is reduced, and the dust-containing gas outside the silicon carbide ceramic membrane 11 is sucked into it. By reducing the air pressure in the silicon carbide ceramic membrane 11, the rate of gas entering the silicon carbide ceramic membrane 11 is increased, and the silicon carbide ceramic membrane 11 is increased. The dust removal efficiency of membrane 11.

During the rotation of the rotating rod 1301, the rotating rod 1301 drives the connecting sleeve 10 to rotate through the connecting block, the connecting sleeve 10 drives the connecting frame 1502 to rotate through the fixing ring 1504 and the bellows 1503, and the connecting sleeve 10 drives the silicon carbide ceramic film 11 Rotate, so that the dust-containing gas ejected from the T-shaped baffle plate 1203 between the rectangular housings 9 evenly impacts on the outer surface of the silicon carbide ceramic film 11. Since the number of teeth of the missing gear 1303 is an integer multiple of the number of teeth of the third gear 1304, When the number of teeth of the third gear 1304 meshes with the missing gear 1303, the number of rotations of the third gear 1304 is an integer, so the number of rotations of the silicon carbide ceramic film 11 is also an integer, so that every part of the outer surface of the silicon carbide ceramic film 11 The impact time of the dust-containing gas is equal, which improves the dust-removing efficiency of the silicon carbide ceramic membrane 11 for the dust-containing gas. For example, when the number of rotations of the silicon carbide ceramic film 11 is 3, the dust adhering to the outer surface of the silicon carbide ceramic film 11 adheres to 3 layers on the outer surface of the silicon carbide ceramic film 11, instead of a non-complete number of turns, resulting in uneven distribution of dust. This method avoids the single impact of gas on one side of the silicon carbide ceramic membrane 11, causing the silicon carbide ceramic membrane 11 to use only a certain part of the dust removal, and the rest basically does not participate in the dust removal, and the full dust removal effect of the silicon carbide ceramic membrane 11 cannot be exerted. The rotation of the ceramic membrane 11 makes the dust attached to its outer surface evenly distributed, which is convenient for subsequent cleaning.

Along with the counterclockwise rotation of rectangular housing 9, when the arc-shaped surface of T-shaped baffle plate 1203 is positioned at the rear side of arc-shaped cavity 203, the arc-shaped surface of T-shaped baffle plate 1203 and the rear side of the inner surface of fixed housing 2 The T-shaped baffle 1203 continues to rotate, the arc surface of the T-shaped baffle 1203 is squeezed by the fixed shell 2 and gradually approaches the separation sleeve 7, and the tension spring 1204 is stretched. When the T-shaped baffle 1203 When the arc surface of 1203 is in contact with the left half of the inner wall of the fixed housing 2, the arc surface of the T-shaped baffle plate 1203 will block the rectangular housing 9, and the dust-containing gas in the arc cavity 203 will no longer enter the separation sleeve. In the cylinder 7, since the radian of the arc surface of the T-shaped baffle 1203 is equal to the radian of the inner surface of the separation sleeve 7, at this time, the middle part of the T-shaped baffle 1203, the rectangular housing 9 and the inner wall of the separation sleeve 7 forms a complete toroidal surface.

When the arc surface of the T-shaped baffle plate 1203 contacts the left half of the inner wall of the fixed housing 2, the third gear 1304 meshes with the arc ring gear 1305, the third gear 1304 starts to rotate in reverse, and the third gear 1304 passes through The rod 1301 drives the fan blade 1306 to rotate in the opposite direction, and the gas in the exhaust cavity 301 is blown into the silicon carbide ceramic membrane 11 through the bellows 1503 and hits the blocking plate. Since the blocking plate is in the shape of a truncated cone, the slope of the blocking plate changes and flows downward. Gas direction, so that the gas disperses and impacts the inner surface of the silicon carbide ceramic membrane 11 around, and blows off the part of the dust attached to the outer surface of the silicon carbide ceramic membrane 11, because the T-shaped baffle 1203, the rectangular housing 9 and the separation The middle part of the inner wall of the sleeve 7 forms a complete annular curved surface to prevent dust from entering the rectangular housing 9, which is not conducive to the subsequent cleaning of the dust in the rectangular housing 9. During the reverse rotation of the fan blade 1306, the rotating rod 1301 passes through the connection. The block and the connecting sleeve 10 drive the silicon carbide ceramic film 11 to rotate. At this time, the operator starts the electric push rod 1401 through the control terminal, and the electric push rod 1401 drives the sliding ring 1403 to move downward through the first pull rod 1402, and the sliding ring 1403 drives the hair The brush 1404 and the annular baffle plate 1405 move downwards. During the downward movement of the hair brush 1404, the electric push rod 1401 drives the connecting frame 1502 and the blocking plate to move downward through the second pull rod 1501, and the connecting frame 1502 moves the bellows 1503. The lower end is stretched, and the bellows 1503 ensures that the gas blown out by the fan blade 1306 is blown into the silicon carbide ceramic membrane 11 through one side of the connecting frame 1502 to avoid gas leakage.

Along with the rotation of the silicon carbide ceramic film 11, the dust on the outer surface of the silicon carbide ceramic film 11 is scraped off by the brush 1404 after being in contact with the brush 1404. Since the longitudinal height of the hair brush 1404 is between the connecting frame 1502 and the blocking plate, when the blocking plate When moving downward synchronously with the brush 1404, the gas that is changed by the blocked disk passes through the silicon carbide ceramic membrane 11 to blow the dust scraped off by the brush 1404, reducing the amount of dust attached to the brush 1404, because the silicon carbide ceramic membrane The dust attached to the outer surface of 11 is evenly distributed, which is convenient for the brush 1404 to clean, and avoids the uneven distribution of dust attached to the outer surface of the silicon carbide ceramic film 11, resulting in excessive accumulation of dust in a certain place, and it is difficult for the brush 1404 to remove the silicon carbide ceramic film 11. The dust on the outer surface is thoroughly cleaned, and due to the interception of the annular baffle 1405, the gas blown out from the silicon carbide ceramic film 11 is prevented from blowing the dust above the sliding ring 1403, which is not conducive to subsequent cleaning. By blocking the downward movement of the disc, The inner surface of the silicon carbide ceramic membrane 11 is blown from top to bottom in order to avoid being too far away from the connecting frame 1502 (air outlet). 11 Evenly blow the air everywhere.

After the dust-containing gas is processed, the operator stops the servo motor 5 through the control terminal, and opens the electromagnetic valve in the storage sleeve 8 through the control terminal, and the operator collects the dust discharged from the storage sleeve 8. This device uses Finish.

To sum up, the separator firstly separates the large particles of impurities from the dust-containing gas through the filter screen of the air inlet 202, and secondly absorbs the dust in the dust-containing gas through the silicon carbide ceramic membrane 11, so that the dust in the dust-containing gas and the gas Separation, and then scrape off the dust on the silicon carbide ceramic membrane 11, so as to perform multi-stage separation treatment on the dust-containing gas, and finally realize the filtration of the dust-containing gas.

During the rotation of the silicon carbide ceramic membrane 11, the silicon carbide ceramic membrane 11 drives the scraper 1602 to rotate through the fixed sleeve 1601, as shown in Figure 11, when the lower surface of the annular baffle 1405 is flush with the upper surface , the blocking plate contacts the circular baffle 1101, and the control terminal stops the electric push rod 1401. At this time, the arc surface of the T-shaped baffle 1203 does not turn to the arc cavity 203. With the rotation of the scraper 1602, The scraper 1602 scrapes off the dust attached to the brush 1404 to prevent the dust attached to the brush 1404 from affecting the subsequent cleaning of the silicon carbide ceramic membrane 11, and the dust between the separation sleeve 7 and the silicon carbide ceramic membrane 11 flows toward the Move down and enter the storage sleeve 8 to be collected. After the dust attached to the brush 1404 is cleaned, the control terminal starts the electric push rod 1401 to reset. When the arc surface of the T-shaped baffle 1203 turns to the arc cavity 203 , continue to repeat the above steps to process the dust-containing gas, and alternately remove dust from the dust-containing gas through three silicon carbide ceramic membranes 11, which increases the dust removal efficiency of the separator.
