2. Product Description
​Heat exchanger
Heat exchanger is a high-efficient heat exchanging equipment used in alcohol, solvent, food ferment, pharmaceutical, petrochemical, refrigeration, organic chemistry, metallurgical industry, suitable for convection heat transfer of liquid to liquid, gas to gas, gas to liquid.
The heat exchanger is 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 comprises non-dismountable and dismountable exchanger. The heat exchanger is made of carbon steel and stainless steel.
Theory 
Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice versa. The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy.
Plate heat exchanger design
The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the inter plate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure. The frame plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to a support column. Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plates.
Channels are formed between the plates and the corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer.

3. New Technology Description

Five-Column Three-Effect Distillation Process
Our company designs and manufactures latestFive-Column Three-Effect Distillation equipment. This new process is promoted on the basis of traditional five-column differential-pressure column and mainly used for super-fine alcohol production.
The key of this process is the heating methods, the steam heats one column directly and transfers theheat to other 4 columnsto achieve three-effect thermal coupling and energy-saving effects.
In terms of electricityefficiency, it can save *0% electricity and avoid the repairing of circulating pumps and also extend the working life of there-boilers.
Double-Mash-Column Three-Effect Distillation Process
This process applies to the production of general-grade alcohol& fuel eth
anol, and it was awarded Chinese national patent, it is the onlysuccessfulapplicationof double mash column & three-effect in the world, which produces general-grade alcohol.
This process is composed by mash column, rectification column and composite column. The composite column functions as mash column and rectification column.
The key of this process is the heating methods: The steam heats one column directly and transfers the heat to other 2 columns to achieve three-effect thermal coupling and energy-saving effects.
The advantage of this process is energy-saving; It saves over *0% steam
