Description
Technical field
The utility model relates to a kind of device preparing methylene fluoride.
Background technology
HFC-32 is important Fluorine contained chemicals, and its depletion of the ozone layer index is 0, and excellent performance in hydrogen fluorohydrocarbon series products, is mainly used in R410A mixing medium, CFC alternative-502 and HCFC-22.
With hydrogen fluoride and methylene dichloride for raw material, liquid phase method or difluoromethane preparing vapor process under fluorination catalyst is as the effect of the catalyzer such as fluorine antimony chloride, fluorine tin chloride, be the main flow route preparing methylene fluoride now, the yield of this technical maturity, product is high.But when raw material fluorinated hydrogen vaporization heating, because the temperature difference is comparatively large, very easily causes hydrogen fluoride vaporizer to reveal, not only waste raw material, and there is safety, environmental issue.
Utility model content
The purpose of this utility model is to provide a kind of device preparing methylene fluoride, and apparatus structure is simple, easy to operate, safety, environmental protection, and hydrogen fluoride vaporizer not easily leaks, and product yield is high, extends the work-ing life of hydrogen fluoride vaporizer, and reduces production energy consumption.
A kind of device preparing methylene fluoride described in the utility model, comprise methylene fluoride storage tank, methylene fluoride storage tank is connected with methylene fluoride vaporizer by pipeline, methylene fluoride vaporizer is connected with interchanger by the first pipeline, interchanger is connected with hydrogen fluoride vaporizer by pipeline, and hydrogen fluoride vaporizer is connected with hydrogen fluoride storage tank by pipeline; First pipeline is connected with reactor by pipeline, and reactor is connected with water wash column by pipeline, and water wash column is connected with soda-wash tower by pipeline, and soda-wash tower is connected with rectifying tower by pipeline, and rectifying tower is connected with finished pot by pipeline.
Methylene fluoride vaporizer is connected with hydrogen fluoride vaporizer by pipeline.
Methylene fluoride vaporizer arranges steam inlet.
Hydrogen fluoride vaporizer arranges vapor condensation water out.
Methylene fluoride vaporizer and hydrogen fluoride vaporizer are used for the vaporization of hydrogen fluoride and methylene dichloride.
Interchanger is used for gas phase fluorination hydrogen and continues heating.
During use, raw material methylene dichloride is vaporized through vaporizer, steam condensation water out enters hydrogen fluoride vaporizer and preheats vaporization to hydrogen fluoride, hydrogen fluoride after vaporization continues heating through interchanger, above-mentioned two kinds of materials enter in the reactor that catalyzer is housed and react, generate methylene fluoride crude product, methylene fluoride crude product obtains methylene fluoride product through water wash column, soda-wash tower, rectifying tower.
Compared with prior art, the utility model has following beneficial effect:
The utility model prepares the device of methylene fluoride, and apparatus structure is simple, easy to operate, safety, environmental protection, and hydrogen fluoride vaporizer not easily leaks, and product yield is high, extends the work-ing life of hydrogen fluoride vaporizer, and reduces production energy consumption.
