Product Description:

1.Product Description:

Pre-heater is a high-efficient heat exchanging equipment used in alcohol, solvent, foodferment, pharmaceutical, petrochemical, refrigeration, organic chemistry, metallurgicalindustry, suitable for convection heat transfer of liquidtoliquid,gas to gas,gas to liquid.

The heatexchangeris divided into tubular heat exchanger, spiral plate heat exchanger.And the tubular heat exchanger comprises condenser, Pre-heater, Re-boiler,Evaporator, drying machine. The spiral plate heat exchanger comprisesnon-dismountable and dismountable exchanger.

The heatexchanger is made of carbon steel and stainless steel.

2.New Technology Description:

Five-ColumnThree-Effect Distillation Process

Our company designs and manufactures latest Five-Column Three-Effect Distillation equipment.This new process is promoted on the basisof traditional five-column differential-pressure column and mainly used forsuper-fine alcohol production.

The key of this process is the heatingmethods,the steam heats one column directly andtransfers theheat to other 4 columnsto achieve three-effect thermal couplingand energy-saving effects.

In terms of electricityefficiency, it can save 50% electricity and avoid the repairing ofcirculating pumps and also extend the working life of there-boilers.

Double-Mash-Column Three-Effect Distillation Process

This process applies to the production ofgeneral-grade alcohol& fuel ethanol, and it was awarded Chinese nationalpatent, it is the onlysuccessfulapplicationof doublemash column & three-effect in the world,whichproduces general-grade alcohol.

This process is composed by mash column,rectification column and composite column. The composite column functions asmash column and rectification column.

The key of this process is the heatingmethods: the steam heats one column directly andtransfers the heat to other 2 columns to achieve three-effect thermal couplingand energy-saving effects.

The advantage of this process is energy-saving;it saves over 40% steam
