W. ZW type alcohol distillation device
There are two series of alcohol distillation devices produced by our company. One is the standardized product designed by Shanghai Pharmaceutical Design Institute specifically for our company: the W-type indirect heating intermittent type. The other is the ZW type direct steam heating alcohol distillation device provided by Shanghai Wuzhou Pharmaceutical Factory based on their years of production experience and produced by our company.
1、 Main purpose
This device is suitable for the recovery of dilute alcohol in industries such as pharmaceuticals, food, light industry, and chemical engineering. It is also applicable to the distillation of other solvents such as methanol. This device can distill dilute alcohol at around 30 ℃ to alcohol at 90 °~95 ° C according to user requirements. The higher the required alcohol content of the finished product, the higher the reflux ratio can be increased, but the output will correspondingly decrease. W-type can also be used for distillation of methanol and other substances.
2、 Equipment structural characteristics and technical performance
·Device features·
This device uses efficient ceramic or stainless steel corrugated packing. The distillation tower body is made of stainless steel, which prevents the phenomenon of iron filings blocking the packing and extends the service life of the device. All equipment parts in this device that come into contact with alcohol, such as condensers, pressure stabilizing tanks, cooling coils, etc., are made of stainless steel to ensure that the finished alcohol is not contaminated. The W-shaped distillation kettle adopts a detachable U-shaped heating tube. During maintenance, the U-shaped heating tube can be removed from the outside of the kettle for easy cleaning of the outer wall of the heating tube and the inner wall of the distillation kettle. ZW type eliminates the need for indirect heating distillation vessels.
The condenser adopts a tubular heat exchanger, and spiral plate heat exchangers can also be supplied according to user requirements. The cooler adopts a coil type cooler, which is equipped with a stabilizing tank and a specific gravity meter.
Other auxiliary equipment such as measuring tanks, alcohol storage tanks, etc. shall be provided by the user. Our company can also process and supply according to user requirements. W-type can be produced intermittently or semi continuously. ZW type is continuous production.
