Recovery device for methyl tert-butyl ether

Abstract

The invention belongs to the field of chemical production devices, and concretely discloses a recovery device for methyl tert-butyl ether. The recovery device comprises a reaction kettle and a supporting frame; a collecting box and a circulating water tank are arranged on one side of the top of the supporting frame; a discharging pipe is arranged at the bottom of one side of the collecting box, the top of the collecting box is communicated with a cooling box mechanism through a first connecting pipe, the cooling mechanism comprises an inner cooling box and an outer cooling box, and a cavity isformed between the inner cooling box and the outer cooling box; a drain pipe is arranged on one side of the outer cooling tank; one end of the drain pipe is connected with the circulating water tank;a water inlet pipe is arranged in the circulating water tank, and the top end of the water inlet pipe penetrates through the circulating water tank and is connected with the inner cooling box; a refrigerator is mounted on one side of the circulating water tank; the output end of the refrigerator is inserted into the circulating water tank and is connected with a cold water pipe; and the top of the reaction kettle is connected with a second connecting pipe, and one end of the second connecting pipe is communicated with the cavity. The collection speed of methyl tert-butyl ether generated by the waste is increased, and the recovery efficiency is improved.

Description

technical field [0001] The invention relates to the field of chemical production devices, in particular to a recovery device for methyl tert-butyl ether. Background technique [0002] MTBE is generally synthesized from methanol and isobutylene with the aid of acidic catalysts, among which resin catalysts are most widely used in industry. In the production process, a small amount of raw materials are not fully reacted and eventually form waste. Most of the existing devices for recycling these waste residues use pressing and stirring methods to make the unreacted raw materials in the waste continue to react and produce tertiary methyl Butyl ether, but the existing recovery device collects methyl tert-butyl ether at a slow rate, which reduces the recovery efficiency. Contents of the invention [0003] The object of the present invention is to provide a recovery device for methyl tert-butyl ether, to solve the problems raised in the above-mentioned background technology.
