Abstract

The invention provides a drawer type split evaporation device for an organic solvent in water. The device comprises a gas-liquid mixing cavity and a gas volatilization cavity, wherein the gas-liquid mixing cavity comprises at least one slot and a hot gas injection assembly capable of being inserted into the slot, and the outer wall of the hot gas injection assembly comprises a hydrophobic microporous material. According to the device, the contact area of an organic solvent in water and hot gas is increased, so that rapid evaporation of the organic solvent in water is achieved; the contact areaof the device is increased, so that the equipment volume is reduced under the condition of the same evaporation capacity; under the condition of using inert gas, the safety problem caused by evaporation is reduced; and the device uses a split type double-cavity structure, and a liquid is forced to pass through the gas-liquid mixing cavity and then can enter the gas volatilization cavity, so thatthe problem that non-uniform gas-liquid mixing of part of liquid in an integrated structure is avoided.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and relates to an organic solvent evaporating device, in particular to a water organic solvent evaporating device, in particular to a drawer-type split water organic solvent evaporating device. Background technique [0002] At present, most of the methods for removing organic solvents in water are rectification, pervaporation or rotary evaporation. Although the above methods are simple to operate, their heating area is limited, resulting in limited heat transfer rate and relatively slow separation efficiency. And rectification consumes a lot of energy, and the volume of the equipment is large; pervaporation has high requirements on the membrane and is limited by the organic solvent composition in water; and rotary evaporation is often limited to small-scale experiments in the laboratory and is not applicable. in mass production. [0003] CN 204619399 U discloses a solvent evaporation device for...
