[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] See also Figure 1-Figure 4 As shown, a MTBE recovery device comprises a pressure tank 1 and a MTBE transmission pipe 5, which is plugged into the pressure tank 1. A cleaning assembly 2 is arranged inside the pressure tank 1. The cleaning assembly 2 comprises a plurality of cold water transmission pipes 201 arranged inside the pressure tank 1, an electric telescopic rod 202 is arranged between the plurality of cold water transmission pipes 201, a push plate 203 is connected to the telescopic end of the electric telescopic rod 202, two connecting plates 204 are arranged between the plurality of cold water transmission pipes 201, a scraper ring 205 is slidably connected to the outer wall of the cold water transmission pipe 201, a slide groove 206 is opened on the connecting plate 204, a connecting rod 207 is fixedly installed on the outer wall of the scraper ring 205, the connecting rod 207 is located inside the slide groove 206 and is slidably connected to the slide groove 206, two connecting plates 204 are cross-arranged between the plurality of cold water transmission pipes 201, and the push plate 203 abuts against the outer wall of the connecting plate 204.

[0025] The pressure tank 1 is a sealed container capable of withstanding high pressure. A cooling system is provided in the pressure tank 1. The temperature of the water in the pressure tank 1 is lowered by the cooling system until the water temperature in the cold water transmission pipe 201 drops to -20°C. When the MTBE in the MTBE transmission pipe 5 floats into the pressure tank 1, the MTBE contacts the outer walls of the cold water transmission pipes 201. Due to the large temperature difference, the MTBE condenses into liquid and forms liquid condensate on the outer walls of the cold water transmission pipes 201.

[0026] At this time, the push plate 203 is driven to move by the electric telescopic rod 202. When the push plate 203 slowly moves toward the side away from the electric telescopic rod 202, one side of the two connecting plates 204 is resisted and moves away from each other. When the connecting plate 204 swings, it drives the connecting rod 207 and the scraper ring 205 to move, so that the scraper ring 205 slides along the outer wall of the cold water transmission pipe 201, so as to facilitate scraping off the liquid methyl tert-butyl ether adhering to the outer wall of the cold water transmission pipe 201;

[0027] When the connecting plate 204 drives the connecting rod 207 to move, the connecting rod 207 will slide along the slide groove 206. Because the scraper ring 205 and the connecting rod 207 can only be parallel, and the movement trajectory of the connecting plate 204 is upward and downward, in order not to affect the swing of the connecting plate 204, the slide groove 206 is provided so that the connecting rod 207 can slide along the slide groove 206. When the push plate 203 moves toward the direction of the electric telescopic rod 202, the multiple scraper rings 205 can move relatively.

[0028] When the push plate 203 moves away from the electric telescopic rod 202 , the multiple scraper rings 205 will separate, thereby achieving cyclic scraping of the outer wall of the cold water transmission pipe 201 to prevent excessive adhesion of liquid MTBE to the outer wall of the cold water transmission pipe 201 .

[0029] See also Figure 2-Figure 3 A support rod 4 is fixedly installed on the inner top wall of the pressure tank 1, a fixed block 3 is fixedly installed on the outer wall of the support rod 4, the electric telescopic rod 202 is fixedly installed on the outer wall of the fixed block 3, and the cold water transmission pipe 201 is fixedly installed on the outer wall of the support rod 4.

[0030] The support rod 4 supports the cleaning assembly 2, and the fixing block 3 is fixed on the outer wall of the support rod 4 to fix and support the electric telescopic rod 202, so that the electric telescopic rod 202 can operate more stably to prevent the electric telescopic rod 202 from falling and loosening.

[0031] See also Figure 3 Two mounting rods 10 are fixedly mounted on the outer wall of the fixing block 3 , the connecting plate 204 is rotatably connected to the outer wall of the mounting rod 10 , a circular baffle 11 is fixedly mounted on the outer wall of the mounting rod 10 , and the outer wall of the circular baffle 11 abuts against the outer wall of the connecting plate 204 .

[0032] The mounting rod 10 supports the connecting plate 204 to prevent the connecting plate 204 from falling and allows the connecting plate 204 to rotate along the outer wall of the mounting rod 10. The circular baffle 11 blocks the connecting plate 204 to prevent the connecting plate 204 from sliding off the outer wall of the mounting rod 10 during the swinging process.

[0033] See also Figure 4 A U-shaped rod 9 is fixedly installed at the bottom and the top of the push plate 203 , a partial area of ​​the connecting plate 204 is located inside the U-shaped rod 9 , and the side of the U-shaped rod 9 away from the push plate 203 is located inside the slide groove 206 .

[0034] The push plate 203 is connected to the two connecting plates 204 through two U-shaped rods 9. Since the push plate 203 needs to slide along the outer wall of the connecting plate 204 when driving the two connecting plates 204 to swing, the U-shaped rod 9 can pull the connecting plate 204 to move without affecting the sliding of the push plate 203.

[0035] See also Figure 2 and Figure 4 A limiting plate 8 is fixedly mounted on one end of the connecting rod 207 away from the scraper ring 205 , and the limiting plate 8 abuts against the outer wall of the connecting plate 204 .

[0036] The limiting plate 8 limits the connection plate 204 to prevent the connection rod 207 from deviating and sliding out of the sliding groove 206 when the connection rod 207 slides along the sliding groove 206 . The limiting plate 8 also prevents the connection plate 204 from sliding out of the connection rod 207 .

[0037] See also Figure 2 One end of the methyl tert-butyl ether transmission pipe 5 extends to the interior of the pressure tank 1, and a connecting frame 6 is fixedly installed at one end of the methyl tert-butyl ether transmission pipe 5 located inside the pressure tank 1. A plurality of through holes 7 are opened on the top of the connecting frame 6. The methyl tert-butyl ether transmission pipe 5 is connected to the interior of the connecting frame 6, and the through holes 7 correspond to the cold water transmission pipe 201.

[0038] The methyl tert-butyl ether in the methyl tert-butyl ether transmission pipe 5 first enters the connection frame 6, and then floats out of the interior of the connection frame 6 through the multiple through holes 7. This structure allows the methyl tert-butyl ether to be more dispersed, so that the methyl tert-butyl ether can float into the pressure tank 1 more dispersedly, and also allows the methyl tert-butyl ether to float directly to the cold water transmission pipe 201, which is convenient for the cold water transmission pipe 201 to condense the methyl tert-butyl ether.

[0039] See also Figure 2 and Figure 4 A support rod 12 is fixedly installed on the outer wall of the two scraper rings 205 , and the support rod 12 is located below the scraper ring 205 . A collecting box 13 is fixedly installed on the bottom end of the support rod 12 , and the collecting box 13 corresponds to the scraper ring 205 .

[0040] Since the scraper ring 205 is in parallel movement, the scraper ring 205 will drive the collecting box 13 to move together through the support rod 12 when moving. The collecting box 13 corresponds to the scraper ring 205. Therefore, when the scraper ring 205 scrapes the liquid methyl tert-butyl ether on the outer wall of the cold water transmission pipe 201, the liquid methyl tert-butyl ether can just fall into the inside of the collecting box 13, thereby realizing the collection of methyl tert-butyl ether, so as to prevent the liquid methyl tert-butyl ether from scattering in the pressure tank 1.

[0041] Working principle:

[0042] The pressure tank 1 is a sealed container capable of withstanding high pressure. A cooling system is provided in the pressure tank 1. The temperature of the water in the pressure tank 1 is lowered by the cooling system until the water temperature in the cold water transmission pipe 201 drops to -20°C. When the MTBE in the MTBE transmission pipe 5 floats into the pressure tank 1, the MTBE contacts the outer walls of the cold water transmission pipes 201. Due to the large temperature difference, the MTBE condenses into liquid and forms liquid condensate on the outer walls of the cold water transmission pipes 201.

[0043] At this time, the push plate 203 is driven to move by the electric telescopic rod 202. When the push plate 203 slowly moves toward the side away from the electric telescopic rod 202, one side of the two connecting plates 204 is resisted and moves away from each other. When the connecting plate 204 swings, it drives the connecting rod 207 and the scraper ring 205 to move, so that the scraper ring 205 slides along the outer wall of the cold water transmission pipe 201, so as to facilitate scraping off the liquid methyl tert-butyl ether adhering to the outer wall of the cold water transmission pipe 201;

[0044] When the connecting plate 204 drives the connecting rod 207 to move, the connecting rod 207 will slide along the slide groove 206. Because the scraper ring 205 and the connecting rod 207 can only be parallel, and the movement trajectory of the connecting plate 204 is upward and downward, in order not to affect the swing of the connecting plate 204, the slide groove 206 is provided so that the connecting rod 207 can slide along the slide groove 206. When the push plate 203 moves toward the direction of the electric telescopic rod 202, the multiple scraper rings 205 can move relatively.

[0045] When the push plate 203 moves away from the electric telescopic rod 202 , the multiple scraper rings 205 will separate, thereby achieving cyclic scraping of the outer wall of the cold water transmission pipe 201 to prevent excessive adhesion of liquid MTBE to the outer wall of the cold water transmission pipe 201 .

[0046] Since the scraper ring 205 is in parallel movement, the scraper ring 205 will drive the collecting box 13 to move together through the support rod 12 when moving. The collecting box 13 corresponds to the scraper ring 205. Therefore, when the scraper ring 205 scrapes the liquid methyl tert-butyl ether on the outer wall of the cold water transmission pipe 201, the liquid methyl tert-butyl ether can just fall into the inside of the collecting box 13, thereby realizing the collection of methyl tert-butyl ether, so as to prevent the liquid methyl tert-butyl ether from scattering in the pressure tank 1.
