Description

Technical Field

[0001] The utility model relates to the technical field of MTBE devices, in particular to an adjustable feeding mechanism for MTBE devices. Background Art

[0002] MTBE (methyl tert-butyl ether) unit is a device used to produce methyl tert-butyl ether. Methyl tert-butyl ether is a high-octane gasoline additive, which mainly increases the octane number of gasoline, improves the combustion performance of gasoline, and reduces the emission of harmful substances in automobile exhaust. MTBE units are usually composed of reactors, catalysts, separation towers, distillation towers and other equipment. Methyl tert-butyl ether is produced through the reaction of isobutylene and methanol. In the process of producing MTBE, an adjustable feeding mechanism for MTBE units is required.

[0003] Most of the feeding mechanisms currently used cannot filter the liquid during feeding, cannot scrape off impurities attached to the filter plate, and cannot accelerate the reaction process by stirring and mixing.

[0004] After searching, the existing patent [CN 202096941 U] discloses a feeding system for an MTBE device, including a primary reactor, a secondary reactor, and a cyclone purifier, wherein the feed port of the cyclone purifier forms an MTBE raw material inlet, and the discharge port of the cyclone purifier is connected to the feed port of the primary reactor. The cyclone purifier uses the centrifugal force generated by the high-speed rotation of the fluid in the cyclone tube to separate the amine liquid droplets from the MTBE raw material, thereby achieving the purpose of MTBE raw material purification or amine liquid recovery. After purification, the MTBE raw material enters the primary reactor and other various equipment, which can reduce the contamination of the catalyst in the MTBE device by the amine liquid, extend the service life of the catalyst, reduce the frequency of catalyst replacement, improve production efficiency, reduce production costs, and reduce pollution to the environment. The MTBE device solves the problem of serious environmental pollution.

[0005] Although the above utility model patent solves the problem of serious environmental pollution, most of the feeding mechanisms currently used cannot filter the liquid during feeding and cannot scrape off the impurities attached to the filter plate. During use, isobutylene and methanol liquids may contain some impurities. If they directly enter the shell through the feed pipe and mix into MTBE liquid, the mixed liquid may be impure, which reduces the accuracy of the device. After a long period of filtration on the filter plate, impurities on the surface of the filter plate will accumulate. If they are not cleaned in time, impurities on the filter plate may accumulate and clog the filter plate, making it impossible to feed the device normally, reducing the practicality of the device, and the reaction process cannot be accelerated by stirring and mixing. During use, relying solely on a catalyst to react may make the reaction time longer, resulting in low working efficiency of the device and poor practicality of the device. Utility Model Content
