Porous membrane pervaporation type organic solvent filtration purification apparatus

Abstract

The invention discloses a porous membrane pervaporation type organic solvent filtration purification apparatus, which comprises a purifier main body and a container, wherein the upstream end of the purifier main body is provided with a filtration screen, four concave grooves are circumferentially arranged along the inner wall of the purifier main body, four projection bodies corresponding to the concave grooves are circumferentially arranged along the outer wall of the container, the projection body and the concave groove are mutually fixed and buckled, the container is filled with active carbon fibers, the inner wall of the container is fixedly provided with pore-free baffles, the bottom end of the container is fixedly provided with an organic filtration membrane, and the downstream end of the organic filtration member is provided with an ultra-filtration membrane. According to the present invention, the porous membrane pervaporation type organic solvent filtration purification apparatus has advantages of simple structure and novel design, can efficiently filter organic solvents, and can conveniently replace active carbon fibers, such that the filtration effect of the porous membrane pervaporation type organic solvent filtration purification apparatus is ideal, and the porous membrane pervaporation type organic solvent filtration purification apparatus is suitable for wide use.

Description

technical field [0001] The invention relates to the field of organic solvent purification devices, in particular to a porous membrane pervaporative filtration organic solvent purification device. Background technique [0002] Many pharmaceutical and fine chemical companies use various organic solvents and catalysts in the production process, such as benzene, hydrocarbons, alcohols, ketones, etc. to complete the product process, resulting in many by-products and various complex Composition of organic waste gas not only pollutes the environment, but also deteriorates production conditions and poses a great risk to human health. Thirdly, there are usually particles that cannot be filtered out by the filter screen in the exhaust gas flow, and these particles will block the pores of the activated carbon, reducing the adsorption capacity of the activated carbon, and once the particles are blocked in the pores of the activated carbon, it is difficult to However, when the existing ...
