Description

Technical Field

[0001] The utility model relates to the technical field of organic solvent recovery, in particular to an organic solvent vaporization removal device. Background Art

[0002] Organic solvents are a large class of organic compounds widely used in life and production. They have a small molecular weight and are found in coatings, adhesives, paints and detergents. Commonly used ones include styrene, perchloroethylene, trichloroethylene, ethylene glycol ether and triethanolamine. Organic solvents can dissolve some organic compounds that are insoluble in water (such as oils, waxes, resins, rubbers, dyes, etc.). They are characterized by being liquid at room temperature and pressure and having high volatility. During the dissolution process, the properties of the solute and the solvent do not change. There are organic solvents with high solubility in water. When water-soluble organic solvents are recycled and reused, they are often mixed with water. Therefore, it is necessary to purify and remove the organic solvents in the mixed solution for recycling. In addition to organic solvents and water, the recovered mixed liquid may also contain ionic substances, particles and other impurities that are difficult to volatilize, and organic substances different from the organic solvents that are the objects of recycling. At present, the recovery of organic solvents often adopts the vaporization removal method, that is, the mixed liquid is filtered using a pervaporation separation membrane that has affinity for the treatment object, so that useless substances such as water can pass through the pervaporation separation membrane and move to the low-pressure side, thereby achieving the purpose of concentrating the organic solvent for recycling, which brings great convenience to the vaporization removal and recovery of organic solvents. However, it is found in the use of the existing organic solvent vaporization removal device that it is not convenient to assemble and disassemble the pervaporation separation membrane, which makes it inconvenient to replace the pervaporation separation membrane in time, and it is easy to cause damage to the pervaporation separation membrane, making it difficult to ensure the removal and concentration effect of the organic solvent, which brings a lot of trouble to the vaporization removal and recovery of the organic solvent.
