Description

Technical Field

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

[0002] Methyl tert-butyl ether (MTBE) is a commonly used gasoline additive with advantages such as increasing gasoline octane rating and reducing exhaust emissions. However, during production and use, MTBE may leak into the environment, causing pollution to water bodies and soil. Therefore, MTBE recycling is necessary to reduce its environmental impact.

[0003] Existing recycling devices cannot issue timely alarms when abnormal temperatures occur, thus failing to ensure the safe operation of the entire recycling device and leading to dangerous situations caused by problems such as temperature runaway. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a methyl tert-butyl ether recovery device.

[0005] This utility model is achieved by the following technical solution: a methyl tert-butyl ether recovery device, including a protective outer tank, an inner tank inside the protective outer tank, a warning light fixedly connected to the top of the inner tank, and a temperature monitor fixedly connected to the top of the inner tank.

[0006] The bottom of the protective outer tank is fixedly connected to a support column, and four support columns are provided. The top of the inner tank is fixedly connected to a water tank, and a circulation pipe is fixedly connected to the surface of the water tank. A cooler is fixedly connected to the surface of the circulation pipe. The bottom of the cooler is fixedly connected to the top of the inner tank, and the surface of the circulation pipe is in contact with the surface of the inner tank. The front end of the protective outer tank is fixedly connected to the rear end of the liquid outlet pipe.

[0007] Through the above technical solution, the warning light and temperature monitor installed on the top of the inner tank can monitor the temperature inside the inner tank in real time. When an abnormal temperature occurs, an alarm can be issued in time to ensure the safe operation of the entire recycling device and prevent dangerous situations caused by temperature runaway. Water droplets generated by cold air on the surface of the circulation pipe fall into the gap between the outer and inner tanks and flow out from the outlet pipe. The gap between the outer and inner tanks can serve as a temporary collection space, where water droplets gather and flow out through the outlet pipe, preventing them from mixing with the methyl tert-butyl ether in the inner tank and avoiding interference with the recycling process.

[0008] As a further improvement to the above solution, the top of the inner tank is fixedly connected to the bottom of the servo motor. The output end of the bottom of the servo motor is connected to the top of the rotating shaft through the inside of the inner tank. The rotating shaft is located inside the inner tank, and stirring blades are fixedly connected to the surface of the rotating shaft. Several stirring blades are provided. Scraper 1 is fixedly connected to one end of each stirring blade that is far apart from each other. There are four scraper 1s. The ends of the four scraper 1s that are far apart from each other are in contact with the inner wall of the inner tank. Scraper 2 is fixedly connected to the bottom of the rotating shaft. There are three scraper 2s. The bottom ends of the three scraper 2s are in contact with the top of the filter plate 1. The filter plate 1 is fixedly connected to the inner wall of the inner tank. The bottom end of the filter plate 1 is in contact with the top of the scraper 3. There are three scraper 3s. A connecting shaft is fixedly connected to one end of each scraper 3 that is close to each other. The top of the connecting shaft is fixedly connected to the bottom ends of the three scraper 2s through the inside of the filter plate 1.

[0009] Through the above technical solution, a servo motor drives a rotating shaft, and the stirring blades on the shaft agitate the methyl tert-butyl ether, accelerating the reaction rate. Simultaneously, scrapers one, two, and three scrape off the condensate from the inner wall of the inner tank and the upper and lower surfaces of filter plate one, respectively. Scraper two is located at the bottom of the rotating shaft and contacts the top of filter plate one, while scraper three is located at the bottom of filter plate one and connected to scraper two via a connecting shaft. When the rotating shaft rotates, scraper two scrapes off the condensate from the top of filter plate one, and scraper three scrapes off the condensate from the bottom of filter plate one. This ensures that both the upper and lower surfaces of filter plate one remain clean, preventing clogging of the filter pores due to condensate buildup, thus ensuring smooth filtration of methyl tert-butyl ether through filter plate one and improving recovery efficiency.

[0010] As a further improvement to the above solution, a second filter plate is provided at the bottom of the first filter plate, the second filter plate is fixedly connected to the inner wall of the inner tank, a discharge inclined plate is fixedly connected to the bottom of the inner wall of the inner tank, and the front end of the inner tank is fixedly connected to the rear end of the discharge pipe through the inside of the protective outer tank.

[0011] With the above technical solution, filter plate one and filter plate two are sequentially installed on the inner wall of the inner tank. The double-layer filter plate setup allows for finer filtration of methyl tert-butyl ether (MTBE). First, after the condensate is scraped off by scrapers one, two, and three, the MTBE undergoes preliminary filtration through filter plate one to remove larger impurities or incompletely reacted substances. Then, it undergoes secondary filtration through filter plate two to further improve the purity of the recovered MTBE. A discharge ramp is fixed to the bottom of the inner tank wall. After filtration, the MTBE flows towards the discharge ramp under gravity, which guides the MTBE smoothly to the discharge pipe, ensuring the successful discharge of the recovered MTBE and completing the recovery process.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention utilizes a dual-layer filter (filter plate one and filter plate two) to achieve fine filtration of methyl tert-butyl ether. After the condensate is scraped off by scraper one, scraper two, and scraper three, the methyl tert-butyl ether undergoes preliminary filtration through filter plate one and then secondary filtration through filter plate two, thereby improving the purity of the recovered methyl tert-butyl ether and ensuring efficient recovery.

[0014] The design of scraper blades one, two, and three effectively prevents liquid condensate generated by cold air from adhering to the inner wall of the inner tank, filter plate one, and other components. This avoids the condensate from re-mixing into the methyl tert-butyl ether and also prevents the condensate from clogging the filter plate, ensuring the smooth progress of the recovery process.

[0015] This invention utilizes a combination of a circulation pipe and a cooler to effectively cool the interior of the inner tank. This cooling method can uniformly regulate the temperature inside the inner tank to a specified temperature, providing a stable temperature environment for the reaction of methyl tert-butyl ether, which is beneficial for improving recovery efficiency and quality.

[0016] The model of the cooler is DS18B20: This is a commonly used digital temperature sensor, which features small size, high accuracy, strong anti-interference ability, and a temperature measurement range of -55℃ to +125℃, with a resolution of 0.0625℃.

[0017] The warning light and temperature monitor installed at the top of the inner tank can monitor the temperature inside the tank in real time. When the temperature is abnormal, an alarm can be issued in time to ensure the safe operation of the entire recycling unit and prevent dangerous situations caused by temperature runaway or other problems.

[0018] The temperature monitor is model TEC1-12706: it is a semiconductor cooler with features such as fast cooling speed, small size, and no noise. The maximum cooling power is 60W, and the maximum temperature difference can reach 60℃. Attached Figure Description

[0029] The bottom of the outer protective tank 1 is fixedly connected to a support column 2, and there are four support columns 2. The top of the inner tank 3 is fixedly connected to a water tank 4. The surface of the water tank 4 is fixedly connected to a circulation pipe 6. The surface of the circulation pipe 6 is fixedly connected to a cooler 5. The bottom of the cooler 5 is fixedly connected to the top of the inner tank 3, and the surface of the circulation pipe 6 is in contact with the surface of the inner tank 3.

[0030] The front end of the protective outer tank 1 is fixedly connected to the rear end of the liquid outlet pipe 7.

[0031] The top of the inner tank 3 is fixedly connected to the bottom of the servo motor 10. The output end of the bottom of the servo motor 10 is connected to the top of the rotating shaft 11 through the inside of the inner tank 3. The rotating shaft 11 is located inside the inner tank 3.

[0032] A stirring blade 12 is fixedly connected to the surface of the rotating shaft 11, and several stirring blades 12 are provided.

[0033] Several stirring blades 12 are fixedly connected to scrapers 13 at their far ends. There are four scrapers 13, and the far ends of the four scrapers 13 are in contact with the inner wall of the inner tank 3.

[0034] The bottom end of the rotating shaft 11 is fixedly connected to scraper 2 14. There are three scraper 2 14. The bottom ends of the three scraper 2 14 are in contact with the top end of filter plate 1 15. Filter plate 1 15 is fixedly connected to the inner wall of the inner tank 3.

[0035] The bottom end of filter plate 15 contacts the top end of scraper 3 17. There are three scrapers 3 17. The ends of the three scrapers 3 17 that are close to each other are fixedly connected to a connecting shaft 16. The top end of the connecting shaft 16 passes through the inside of filter plate 15 and is fixedly connected to the bottom end of the three scrapers 2 14.

[0036] A filter plate 18 is provided at the bottom of filter plate 15. Filter plate 18 is fixedly connected to the inner wall of inner tank 3.

The front end of inner tank 3 is fixedly connected to the rear end of discharge pipe 20 through the inside of protective outer tank 1.

[0037] The implementation principle of the methyl tert-butyl ether recovery device in this embodiment is as follows: The circulation pipe 6 generates cold air under the action of the cooler 5. The cold air cools the inside of the inner tank 3 by contacting its surface. When the internal temperature of the inner tank 3 drops to a specified temperature, the methyl tert-butyl ether inside begins to react. During the cooling process, water droplets are generated on the surface of the circulation pipe 6 due to the cold air. These water droplets fall into the gap between the outer protective tank 1 and the inner tank 3, and then flow out from the outlet pipe 7. The liquid condensate of the methyl tert-butyl ether in the inner tank 3 due to the cold air adheres to the inside of the inner tank 3 and the surface of the filter plate 15. At this time, the servo motor 10 drives the rotating shaft 11 to rotate, and the stirring blades 12 on the rotating shaft 11 stir the methyl tert-butyl ether. At the same time, scrapers 13, 14, and 17 scrape off the condensate from the inner wall of the inner tank 3 and the upper and lower surfaces of the filter plate 15, respectively. The methyl tert-butyl ether after being processed by the scrapers first undergoes preliminary filtration through the filter plate 15 to remove some impurities and unreacted substances. Then, methyl tert-butyl ether undergoes a second filtration through filter plate 18 to further improve its purity. After two filtrations, the methyl tert-butyl ether flows to the discharge inclined plate 19 under gravity, which guides it to the discharge pipe 20, thus completing the recovery process of methyl tert-butyl ether.
