Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to waste gas treatment equipment for carbon fiber production. Background Art

[0002] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It is made of acrylic and viscose fibers through high-temperature oxidation and carbonization. A lot of waste gas will be generated in the production of carbon fiber. These waste gases need to be treated by waste gas treatment equipment, and the waste gas treatment spray tower is one of them. The waste gas enters the interior through the bottom of the tower body. Under the action of fillers and spraying, the harmful substances in the waste gas are dissolved in water, thereby achieving the purpose of purifying the waste gas. The role of the filler is to increase the contact opportunity between the waste gas and the spray liquid, so as to improve the waste gas treatment effect. Then the waste gas becomes clean gas after treatment and is discharged into the air.

[0003] In the existing technology, after the exhaust gas enters the bottom of the tower body, it directly passes through the inside of the filler. The residence time of the exhaust gas inside the filler is short, thereby reducing the contact time between the exhaust gas and the spraying liquid, which also affects the exhaust gas treatment effect. For this reason, we propose a waste gas treatment equipment for carbon fiber production. Summary of the Invention

[0006] The rotating assembly is arranged between the two groups of fillers and is used to process the passing exhaust gas again;

[0007] The driving assembly is arranged inside the tower body and is used to drive the rotating assembly and the two groups of fillers to rotate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The present invention has a delay mechanism designed to drive the two groups of filler bodies to rotate through a double-headed motor during use, so that when the exhaust gas passes through the interior of the two groups of filler bodies, the path of the exhaust gas inside the filler body becomes tortuous, thereby prolonging the residence time of the exhaust gas. Moreover, when the exhaust gas passes through the position between the two groups of filler bodies, it will pass through the outer partition filler plate, filler plate frame and triangular filler plate in the opposite direction of rotation to the filler body, so that the exhaust gas contacts the spray liquid on the outer surface of the outer partition filler plate, filler plate frame and triangular filler plate, further increasing the contact opportunity between the exhaust gas and the spray liquid and improving the treatment effect of the exhaust gas.

[0020] (2) The filter element designed in the present invention will first filter out the particulate impurities in the exhaust gas through the filter plate when the exhaust gas enters the bottom of the inner wall of the tower body, and pre-filter the particulate impurities. Then, the convex plate is driven to rotate by the rotating cross bar to make it contact and knock the filter plate below, so that the particulate impurities attached to the bottom of the filter plate can be shaken off, reducing the situation where the particulate impurities attached to the bottom of the filter plate affect the flow rate of the exhaust gas passing through the filter plate, and facilitating use.

[0033] The rotating assembly includes a packing plate frame 206, with outer packing plates 208 fixedly mounted on the top and bottom of the packing plate frame 206. Multiple sets of triangular packing plates 204 are fixedly mounted on the packing plate frame 206. A middle bearing 203 is mounted on the top of the outer packing plates 208 to support the packing plate frame 206, the outer packing plates 208, and other structures. An upper gear ring 207 is fixedly mounted on the inner wall of the middle bearing 203.

[0034] The tower body 100 is internally provided with a central rotating column 212, one end of which is fixedly provided with a central gear 216, which is meshed with the upper gear ring 207;

[0035] An upper bearing 201 is provided on the outside of the filler body 101 to support the filler body 101. The upper bearing 201 is fixed to the inner wall of the tower body 100. An upper ring gear 200 is fixed on the top of the filler body 101. Two sets of outer rotating columns 213 are rotated inside the tower body 100. An outer gear 221 is fixed at one end of the outer rotating column 213, and the outer gear 221 is meshed with the upper ring gear 200.

[0036] Example 2

[0037] Based on Example 1, please refer to Figure 1-Figure 7The driving assembly includes a double-headed motor 209 fixed to the outside of the tower body 100 and a concave plate 211 fixed to the outside of the tower body 100. The double-headed motor 209 can drive the filler body 101, the filler plate frame 206, the cross bar 302 and other structures to rotate. The two sets of working ends of the double-headed motor 209 are fixed with main vertical rods 210. The top of the main vertical rod 210 passes through the inside of the concave plate 211. The main vertical rod 210 and the auxiliary vertical rod 214 are both rotatably set on the concave plate 211.

[0038] Two sets of outer transverse bevel gears 223 are fixedly provided on the outside of the main vertical rod 210, and an outer vertical bevel gear 222 is fixedly provided on the other end of the outer rotating column 213. The outer vertical bevel gears 222 are meshed with the outer transverse bevel gears 223.

[0039] A secondary vertical rod 214 is rotatably provided on the concave plate 211. The rotation of the secondary vertical rod 214 can indirectly drive the filler plate frame 206 and other structures to rotate accordingly. A middle horizontal bevel gear 217 is fixedly provided on the top of the secondary vertical rod 214. A middle vertical bevel gear 218 is fixedly provided on the other end of the middle transfer column 212. The middle vertical bevel gear 218 is meshed with the middle horizontal bevel gear 217.

[0040] A first rotating wheel 219 is fixedly sleeved on the bottom of the auxiliary vertical rod 214 , and a second rotating wheel 220 is fixedly sleeved on the outside of the main vertical rod 210 . The outer wall of the first rotating wheel 219 contacts the outer wall of the second rotating wheel 220 .

[0041] The present invention uses a designed delay mechanism to drive the two groups of filler bodies 101 to rotate through a double-headed motor 209 during use, so that when the exhaust gas passes through the interior of the two groups of filler bodies 101, the path of the exhaust gas inside the filler body 101 becomes tortuous, thereby extending the residence time of the exhaust gas. Moreover, when the exhaust gas passes through the position between the two groups of filler bodies 101, it will pass through the outer partition filler plate 208, the filler plate frame 206 and the triangular filler plate 204 that rotate in the opposite direction to the filler body 101, so that the exhaust gas contacts the spray liquid on the outer surface of the outer partition filler plate 208, the filler plate frame 206 and the triangular filler plate 204, further increasing the contact opportunity between the exhaust gas and the spray liquid and improving the treatment effect of the exhaust gas.

[0042] During use, the double-headed motor 209 is started, and then the two sets of working ends drive the main vertical rod 210 to rotate. The main vertical rod 210 drives the two sets of outer horizontal bevel gears 223 to rotate, which in turn drives the outer vertical bevel gear 222 to rotate, thereby driving the outer rotating column 213 and the outer gear 221 to rotate. Then, the upper gear ring 200 and the filler body 101 engaged with the outer gear 221 rotate, and at this time, the two sets of filler bodies 101 rotate in the same direction.

[0043] When the main vertical rod 210 rotates, it will also drive the second rotor 220 and the first rotor 219 to rotate. The first rotor 219 drives the secondary vertical rod 214 to rotate. When the second rotor 220 rotates, it will drive the first rotor 219 to rotate in the opposite direction, and then drive the secondary vertical rod 214 to rotate in the opposite direction of the main vertical rod 210. Then, the secondary vertical rod 214 drives the middle horizontal bevel gear 217, the middle vertical bevel gear 218, the middle transfer column 212 and the middle gear 216 to rotate. Then, the rotating middle gear 216 drives the upper gear ring 207, the filler plate frame 206, the triangular filler plate 204 and the outer partition filler plate 208 to rotate. At this time, the rotation direction of these structures is opposite to the rotation direction of the filler body 101. When the exhaust gas enters the bottom of the inner wall of the tower body 100, it will first pass through The packing body 101 rotates at the bottom. After the exhaust gas enters the rotating packing body 101, the exhaust gas located inside the packing body 101 will also rotate under the influence of the rotating force. At this time, the time the exhaust gas passes through the packing body 101 is increased, and the residence time of the exhaust gas passing through the packing body 101 is increased. Then the exhaust gas enters the rotating packing plate rack 206, the triangular packing plate 204 and the outer partition packing plate 208, which can make the exhaust gas contact with the spray liquid on the outer surface of the packing plate rack 206, the triangular packing plate 204 and the outer partition packing plate 208, further increasing the contact opportunity with the spray liquid and improving the treatment effect of the exhaust gas. Finally, the exhaust gas is processed inside the rotating packing body 101 at the top, and finally discharged to the outside through the clean air outlet at the top of the tower body 100.

[0044] Example 3

[0045] Based on Example 2, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 , a filter element is provided at the bottom of the tower body 100, and the filter element includes an annular frame 301 fixed to the bottom of the inner wall of the tower body 100 and a filter plate 300 slidably arranged inside the tower body 100, and the filter plate 300 can filter the particulate impurities in the exhaust gas passing through, thereby reducing the effect of particulate impurities entering the interior of the filler body 101 and causing blockage therein. A cross bar 302 is also rotatably provided inside the tower body 100, and a convex plate 303 is fixedly provided on the outside of the cross bar 302. The top of the convex plate 303 is an arc-shaped structure, which makes it easier to knock on the filter plate 300 below and cause it to shake. A lower vertical conical gear 307 is fixed on the end of the cross bar 302, and a lower horizontal conical gear 306 is fixed on the outside of the main vertical rod 210, and the lower vertical conical gear 307 is meshed with the lower horizontal conical gear 306;

[0046] Three groups of T-shaped rods 304 are slidingly set inside the filter plate 300, and the bottom of the T-shaped rod 304 is fixedly connected to the annular frame 301. The outside of the T-shaped rod 304 is provided with a connecting spring 305, and the top and bottom of the connecting spring 305 are respectively fixed on the filter plate 300 and the annular frame 301.

[0047] The filter element designed in the present invention will first filter out the particulate impurities in the exhaust gas through the filter plate 300 when the exhaust gas enters the bottom of the inner wall of the tower body 100, and pre-filter the particulate impurities. Then, the rotating cross bar 302 drives the convex plate 303 to rotate so that it contacts and knocks the filter plate 300 below, so that the particulate impurities attached to the bottom of the filter plate 300 can be shaken off, reducing the particulate impurities attached to the bottom of the filter plate 300 and affecting the flow rate of the exhaust gas passing through the filter plate 300, making it convenient to use.

[0048] After the cam 303 rotates to the bottom, it will contact and knock the filter plate 300 below. Then, the filter plate 300 moves downward, and the connecting spring 305 begins to compress after being squeezed by the filter plate 300. When the cam 303 rotates to the top, the connecting spring 305 will reset, pushing the filter plate 300 to rise and return to its original position. During this period, the particulate impurities attached to the bottom of the filter plate 300 will be shaken off, reducing the particulate impurities attached to the bottom of the filter plate 300 and affecting the flow rate of the exhaust gas through the filter plate 300.

[0049] In this embodiment, a clean gas outlet is provided at the top of the tower body 100 , and an exhaust gas inlet is provided at the bottom of the tower body 100 .

[0050] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
