Multifunctional solvent rectification recovery device

Abstract

A multifunctional solvent rectification recovery device comprises multiple stages of solvent rectification recovery mechanisms. Each stage of solvent rectification recovery mechanism comprises a rectifying tower, a reboiler, a condenser and a reflux tank, wherein the inlet end of the rectifying tower is communicated with an input pipeline, the inlet end of the reboiler is communicated with the liquid phase outlet end of the rectifying tower, the liquid phase outlet end of the reboiler is communicated with an output pipeline, the gas phase outlet end of the reboiler is communicated with the inlet end of the rectifying tower, the gas phase outlet end of the rectifying tower is communicated with the inlet end of the condenser, the outlet end of the condenser is communicated with the reflux tank, the reflux tank is communicated with a discharge pipeline, and the discharge pipeline is further connected with a reflux pipeline communicated with the rectifying tower. The input pipeline of thelater-stage solvent rectification recovery mechanism is communicated with the output pipeline of the previous-stage solvent rectification recovery mechanism. The device is reasonable in design and high in automation degree, waste can be turned into wealth, waste solvents generated by medical and chemical enterprises can be rectified, recycled and reused, and coordination and unification of society, economy and environmental governance are achieved.

Description

technical field [0001] The invention relates to the technical field of solvent recovery, in particular to a multifunctional solvent rectification recovery device, and also relates to a recovery method of the multifunctional solvent rectification recovery device. Background technique [0002] In the process of industrial production, various solvents are needed, so a large amount of waste solvents will also be produced. Especially in pharmaceutical and chemical enterprises, the products in the production process change rapidly, and the waste solvents produced are complex and diverse, and they are directly treated and discharged. The amount is large, the processing cost is high, and it will cause a waste of solvent resources. [0003] At present, although there are already devices capable of recovering solvents, the existing related devices are generally relatively large in size, require high site space, and have relatively single functions, which cannot be adjusted according t...

Problems solved by technology

[0002] In the process of industrial production, various solvents are needed, so a large amount of waste solvents will also be produced. Especially in pharmaceutical and chemical enterprises, the products in the production process change rapidly, and the waste solvents produced are complex and diverse, and they are directly treated and discharged. The amount is large, the processing cost is high, and it will cause a waste of solvent resources

[0003] At present, although there are already devices capable of recovering solvents, the existing related devices are generally relatively large in size, require high site space, and have relatively single functions, which cannot be adjusted according to the waste solvents to be processed, making it difficult to solve the problem , The bottleneck of complex types of solvents in the fine chemical industry, the small amount of a single type, and difficulty in recycling
