Abstract

The utility model relates to the technical field of methyl tertiary butyl ether and discloses a methyl tertiary butyl ether recovery device which comprises a protective outer tank, wherein an inner tank is arranged in the protective outer tank, the top end of the inner tank is fixedly connected with a warning lamp, and the top end of the inner tank is fixedly connected with a temperature monitor. The utility model cools the inner tank through the contact of the cold air with the surface of the inner tank. When the temperature inside the inner tank is reduced to the specified temperature, the methyl tertiary butyl ether inside starts to react, and during the refrigeration process, water drops are generated on the surface of the circulating pipe due to the cold air, fall into a gap between the protective outer tank and the inner tank, and then flow out of the liquid outlet pipe. Whereas the liquid condensate of methyl tertiary butyl ether in the inner vessel due to cold gas will adhere to the inner vessel interior and to one surface of the filter plate. At this time, the servo motor drives the rotating shaft to rotate, and stirring blades on the rotating shaft stir methyl tertiary butyl ether, and meanwhile, the first scraping plate, the second scraping plate and the third scraping plate scrape condensate on the inner wall of the inner tank and the upper surface and the lower surface of the filter plate respectively.

Description

Methyl tertiary butyl ether recovery unit Technical Field The utility model relates to the technical field of methyl tertiary butyl ether, in particular to a methyl tertiary butyl ether recovery device. Background Methyl tert-butyl ether (MTBE) is a common gasoline additive and has the advantages of improving the octane number of gasoline, reducing the exhaust emission and the like. However, during production and use, MTBE may leak into the environment, causing pollution to the water and soil. Thus, there is a need for recovery processing of MTBE to reduce its environmental impact. When the temperature of the existing recovery device is abnormal, an alarm cannot be given out timely, and the safe operation of the whole recovery device cannot be guaranteed, so that dangerous situations caused by the problems of temperature runaway and the like are caused.
