Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the described specific embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0020] Such as figure 1 As shown, the fluorosurfactant production system of the present invention includes a reaction tank 1 , an evaporation tank 2 and solvent storage tanks 3 , 4 , and 5 . The top of the reaction tank 1 is provided with a feeding port 13 and a solvent liquid inlet, and the bottom is provided with a solvent liquid outlet. The reaction tank 1 is also provided with a heating cycle and temperature control unit 10. The heating cycle and temperature control system 10 can be controlled at ±0.1°C The reaction temperature in the reaction tank 1 is precisely controlled within the temperature range. A solvent inlet valve S11 is set at the solvent inlet at the top of the reaction tank 1, and...

Abstract

The invention relates to a production system for a fluorinated surfactant. The production system comprises a reaction tank provided with a precise temperature controlling device, wherein a filter device is connected with a reaction system, containing a solvent after reaction, through a peristaltic pump; a solid catalyst is recovered, a solvent system after reaction enters an evaporation tank, solvents are evaporated and condensed by a vacuum system and a reflux condensing system, the evaporated solvents enter respective storage tanks after being dried, a supply pump adds required solvents to the reaction tank again through a pipeline, and cycle use of the solvents is completed. With adoption of the production system, recovery and cycle use of the solid catalyst and the solvents are realized in a discontinuous production process on the scale of 50 kg-5 ton.

Description

technical field [0001] The invention relates to a discontinuous chemical reaction unit, in particular to a fluorosurfactant production system. Background technique [0002] In discontinuous chemical unit reactions, since materials such as solvents and catalysts cannot be recycled, a large amount of industrial "three wastes" will be generated, which will have a great impact on the environment and waste a lot of resources. The green production system of the fluorine surfactant of the present invention can realize the recovery and recycling of the reaction solvent and the solid catalyst in the discontinuous chemical unit reaction. The whole system includes reaction equipment system, filtration equipment system, evaporation equipment system and solvent circulation storage equipment system. Contents of the invention [0003] Aiming at the above-mentioned shortcomings and deficiencies of the prior art, the present invention aims to provide a fluorosurfactant production system t...
