Description

Technical Field

[0001] This utility model relates to the field of methyl tert-butyl ether recovery, and in particular to a methyl tert-butyl ether recovery device. Background Technology

[0002] In the current process of recovering methyl tert-butyl ether (MTBE) from waste gas using activated carbon filter cotton, the concentration of MTBE in each part of the activated carbon filter cotton varies. As a result, some areas of the activated carbon filter cotton become saturated before others. The pore structure of the saturated areas of the activated carbon filter cotton is occupied or blocked. With the overall waste gas flow rate remaining constant and the space for air passage decreasing, the waste gas will concentrate and pass through the unsaturated areas of the activated carbon filter cotton quickly. This causes some of the MTBE in the waste gas to pass directly through the activated carbon filter cotton without effective adsorption, thus affecting the recovery efficiency of MTBE in the waste gas. Utility Model Content

[0007] As a further preferred option, the diverter is configured as a disc structure.

[0008] As a further preferred embodiment, it also includes a support rod 1, a sliding block 1, a spring 1, a long rod 1, a support rod 2, a sliding block 2, a spring 2, a long rod 2, a gas sensor, and a pulling assembly; the rectangular frame 2 is rotatably connected to the support rod 1, and the support rod 1 is in contact with the activated carbon filter cotton; the rectangular frame 2 is slidably connected to two sliding blocks 1; each sliding block 1 is fixedly connected to a spring 1, and all springs 1 are fixedly connected to the rectangular frame 2; all sliding blocks 1 are rotatably connected to a long rod 1, and the long rod 1 is in contact with the activated carbon filter cotton; the upper right pivot rod, support rod 1, and long rod 1 cooperate to move the activated carbon filter cotton... A V-shaped section is formed; the recycling bin is rotatably connected to two support rods II, and all support rods II are in contact with the activated carbon filter cotton; the recycling bin is slidably connected to two sliding blocks II; each sliding block II is fixedly connected to a spring II, and all springs II are fixedly connected to the recycling bin; all sliding blocks II are rotatably connected to a long rod II, and the long rod II is in contact with the activated carbon filter cotton, and the long rod II is located below the two support rods II; a gas sensor is fixedly connected to the recycling bin; the recycling bin is connected to two pulling components for moving sliding blocks I and II, and each pulling component is connected to the corresponding sliding block I and sliding block II.

[0010] This invention has the following advantages: The rectangular activated carbon filter cotton repeatedly adsorbs methyl tert-butyl ether (MTBE) in the waste gas, resulting in more thorough MTBE recovery. Simultaneously, the motor and rotating shaft drive the activated carbon filter cotton to rotate, continuously replacing filter section one and filter section two. Combined with a regeneration component, the activated carbon filter cotton is regenerated online, allowing filter section one and filter section two to continuously adsorb MTBE without saturation. This avoids the problem in existing technologies where the concentration of MTBE in each part of the activated carbon filter cotton varies, causing some areas to saturate before others, resulting in some MTBE in the waste gas passing through the activated carbon filter cotton without effective adsorption, thus affecting the MTBE recovery effect.

[0011] By adding a diversion component, the exhaust gas is directed more evenly to the first filter section, allowing the first filter section to better adsorb methyl tert-butyl ether.

[0012] By adding support rod one, sliding block one, spring one, long rod one, support rod two, sliding block two, spring two, long rod two, gas sensor and pulling assembly, the overall length of the V-shaped section is increased, allowing the V-shaped section to absorb more methyl tert-butyl ether. This avoids the problem that when the concentration of methyl tert-butyl ether in the exhaust gas is too high, the filter section one will quickly become saturated. At this time, the pore structure of the filter section one will be occupied or blocked, causing a large amount of exhaust gas to be unable to pass through the filter section one, thus affecting the methyl tert-butyl ether recovery efficiency.

[0021] Example 1

[0022] A recovery device for methyl tert-butyl ether, such as Figures 1-5 As shown, it includes a recycling bin 1, a rectangular frame 1 2, and a rectangular frame 2 3; the air inlet of the recycling bin 1 is connected to an external waste gas conveying device; the air outlet of the recycling bin 1 is connected to an external waste gas emission device; the right side of the recycling bin 1 is connected to the rectangular frame 1 2; the left side of the recycling bin 1 is connected to the rectangular frame 2 3.

[0023] It also includes a rotating shaft 4, a motor 5, activated carbon filter cotton 6, and a regeneration component; two vertically distributed rotating shafts 4 are rotatably connected to rectangular frame 2; two other vertically distributed rotating shafts 4 are rotatably connected to rectangular frame 3; two vertically distributed motors 5 are bolted to rectangular frame 2, and the output shaft of each motor 5 is fixedly connected to the corresponding rotating shaft 4; all rotating shafts 4 are connected to the rectangular activated carbon filter cotton 6, and the activated carbon filter cotton 6 is slidably connected to rectangular frame 2. The activated carbon filter cotton 6 is used to recover methyl tert-butyl ether in the waste gas; a regeneration component is connected to rectangular frame 2.

[0024] The regeneration assembly includes a conveying pipe 111 and a recovery pipe 112; the recovery box 1 has a cavity 101; the cavity 101 has several air inlets 102; the cavity 101 is connected to the conveying pipe 111, and the conveying pipe 111 is connected to an external inert gas conveying device; the rectangular frame 2 has a cavity 201; the cavity 201 has several air outlets 202; the cavity 201 is connected to the recovery pipe 112, and the recovery pipe 112 is connected to an external inert gas recovery device; the cavity 101, air inlets 102, cavity 201, air outlets 202, conveying pipe 111 and recovery pipe 112 work together to regenerate the activated carbon filter cotton 6 online.

[0025] It also includes a diverter 121; the recovery box 1 is fixedly connected to a diverter 121 for diverting the exhaust gas. The diverter 121 has several round holes and is located directly above the air inlet of the recovery box 1.

[0026] The diverter 121 is configured as a disc structure, which is used to enable the diverter 121 to better divert the exhaust gas.

[0027] First, control the external exhaust gas conveying equipment to convey the exhaust gas to the recovery box 1, so that the exhaust gas moves upward in the recovery box 1 and then enters the external emission equipment.

[0028] As the waste gas moves within the recovery box 1, the portion of the rectangular activated carbon filter cotton 6 near the inlet of the recovery box 1 will be described as filter section 1 601, and the portion near the outlet of the recovery box 1 will be described as filter section 2 602. When the waste gas passes through filter section 1 601, the methyl tert-butyl ether in the waste gas is adsorbed by filter section 1 601. During this process, when the concentration of methyl tert-butyl ether in each part of filter section 1 601 is different, some areas of filter section 1 601 may reach saturation before other areas. As a result, some methyl tert-butyl ether in the waste gas may pass directly through filter section 1 601 without effective adsorption. Since the waste gas also needs to pass through filter section 2 602 after passing through filter section 1 601, the methyl tert-butyl ether in the waste gas that was not effectively adsorbed by filter section 1 601 will be adsorbed by filter section 2 602, making the recovery of methyl tert-butyl ether in the waste gas more thorough.

[0029] Furthermore, during the movement of the waste gas within the recovery box 1, the output shaft of the control motor 5 drives the activated carbon filter cotton 6 to rotate via the corresponding rotating shaft rod 4, causing the first filter section 601 and the second filter section 602 to be continuously replaced. Simultaneously, the control of the external inert gas delivery equipment sequentially sprays inert gas through the delivery pipe 111, cavity 101, and air inlet 102 to the part of the activated carbon filter cotton 6 that passes through the rectangular frame 2. After the inert gas passes through the activated carbon filter cotton 6, it flows into the external inert gas recovery equipment sequentially through the air outlet 202, cavity 201, and recovery pipe 112. When the inert gas passes through the activated carbon filter cotton 6, it carries away the methyl tert-butyl ether on the part of the activated carbon filter cotton 6 that passes through the rectangular frame 2, thereby achieving online regeneration of the activated carbon filter cotton 6. This allows the first filter section 601 and the second filter section 602 to continuously adsorb methyl tert-butyl ether without saturation.

[0030] In this way, the rectangularly arranged activated carbon filter cotton 6 adsorbs methyl tert-butyl ether (MTBE) in the waste gas multiple times, making the recovery of MTBE in the waste gas more thorough. At the same time, the motor 5 and the rotating shaft 4 drive the activated carbon filter cotton 6 to rotate, so that the first filter section 601 and the second filter section 602 are continuously replaced. With the help of the regeneration component, the activated carbon filter cotton 6 is regenerated online. This allows the first filter section 601 and the second filter section 602 to continuously adsorb MTBE without saturation. This avoids the situation in the prior art, where the concentration of MTBE in each part of the activated carbon filter cotton 6 is different. In this case, some areas of the activated carbon filter cotton 6 will reach saturation before other areas, causing some MTBE in the waste gas to pass through the activated carbon filter cotton 6 without effective adsorption, thus affecting the recovery effect of MTBE in the waste gas.

[0031] Furthermore, the addition of a diversion component 121 allows the exhaust gas to enter the recovery box 1, impact the surface of the diversion component 121, and be diverted by it. This prevents the exhaust gas from concentrating and rushing towards the filter section 601. During this diversion process, the exhaust gas will also move directly upward through the round holes on the diversion component 121, meaning the exhaust gas will be divided into multiple small streams that move upward. This allows the exhaust gas to flow more evenly towards the filter section 601, enabling the filter section 601 to better adsorb methyl tert-butyl ether.

[0032] Example 2

[0033] Based on Example 1, such as Figures 1-6As shown, it also includes a support rod 211, a sliding block 212, a spring 213, a long rod 214, a second support rod 215, a second sliding block 216, a second spring 217, a second long rod 218, a gas sensor 219, and a pulling assembly; the second rectangular frame 3 is rotatably connected to the support rod 211, and the support rod 211 is in contact with the activated carbon filter cotton 6; the second rectangular frame 3 is slidably connected to two sliding blocks 212 distributed front and back; each sliding block 212 is fixedly connected to a spring 213, and all springs 213 are fixedly connected to the second rectangular frame 3; all sliding blocks 212 are rotatably connected to a long rod 214, and the long rod 214 is in contact with the activated carbon filter cotton 6; the recycling box 1 is rotatably connected to two left and right distributed... Support rod 215, and all support rods 215 are in contact with activated carbon filter cotton 6; two sliding blocks 216 are slidably connected to the recovery box 1; each sliding block 216 is fixedly connected with a spring 217, and all springs 217 are fixedly connected to the recovery box 1; all sliding blocks 216 are rotatably connected to a long rod 218, and the long rod 218 is in contact with the activated carbon filter cotton 6, and the long rod 218 is located below the two support rods 215; a gas sensor 219 for detecting the concentration of methyl tert-butyl ether in the exhaust gas is bolted to the recovery box 1; the recovery box 1 is connected to two pulling components distributed front and back, and each pulling component is connected to the corresponding sliding block 212 and sliding block 216.

[0034] The pulling assembly includes a connecting plate 221, a take-up cord 222, and a rope 223; the recycling bin 1 is slidably connected to the connecting plate 221, and both ends of the connecting plate 221 are fixedly connected to the corresponding sliding block 1 212 and sliding block 216 respectively; the recycling bin 1 is bolted to the take-up cord 222; the take-up cord 222 winds up the rope 223, and the rope 223 passes into the recycling bin 1 and is fixedly connected to the connecting plate 221.

[0035] Considering that although the activated carbon filter cotton 6 can be rotated and regenerated online by the regeneration component, so that the filter section 601 can continuously adsorb methyl tert-butyl ether without saturation, the filter section 601 will quickly become saturated when the concentration of methyl tert-butyl ether in the exhaust gas is too high. At this time, the pore structure of the filter section 601 will be occupied or blocked, resulting in a large amount of exhaust gas being unable to pass through the filter section 601, thus affecting the recovery efficiency of methyl tert-butyl ether.

[0036] Therefore, support rod 211, sliding block 212, spring 213, long rod 214, support rod 215, sliding block 216, spring 217, long rod 218, gas sensor 219, and pulling assembly are added. When the exhaust gas passes through the recovery box 1, the concentration of methyl tert-butyl ether in the exhaust gas is detected by the gas sensor 219. When the concentration of methyl tert-butyl ether in the exhaust gas is too high, the coil take-up device 222 is controlled. Winding up rope 223 causes rope 223 to move upward via connecting plate 221, driving sliding block 1 212, long rod 1 214, sliding block 2 216, and long rod 2 218, compressing spring 1 213 and spring 2 217. During this process, as long rod 1 214 and long rod 2 218 move upward, the V-shaped portion 603 of activated carbon filter cotton 6 located between the upper right pivot rod 4 and support rod 1 211 will shrink, while the filter section 1 601 will... Figure 5 The state shown becomes as follows Figure 6 The V-shaped configuration shown increases the overall length of the V-shaped section 603, allowing it to absorb more methyl tert-butyl ether. This prevents the filter section 601 from becoming rapidly saturated when the concentration of methyl tert-butyl ether in the exhaust gas is too high. In this case, the pore structure of the filter section 601 would be occupied or blocked, causing a large amount of exhaust gas to be unable to pass through the filter section 601, thus affecting the methyl tert-butyl ether recovery efficiency.
