Product Description:

1.Product Description:

Re-boiler is ahigh-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. Re-boiler is made of carbon steel and stainless steel.

2.New Technology Description:

Five-ColumnThree-Effect Distillation Process

Our company designs and manufactures latestFive-ColumnThree-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 DistillationProcess

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;itsaves over 40% steam

Q:What is a floating head heat exchanger?
One end of the floating head heat exchanger tube plate and the shell fixed, and the other end of the tube plate can float freely in the shell, shell and tube bundle on the expansion is free, so when the temperature difference between the two media, the tube bundle and
Q:What is the heat exchanger installation method?
The other for the concrete foundation, the heat exchanger through the saddle bearing by the anchor bolts with the foundation firmly connected.
Q:Heat exchanger performance characteristics?
1. Energy efficient, the heat transfer coefficient of 6000-8000W / m2.0C.
Q:What is a plate heat exchanger?
The most typical wall heat exchanger, its application in the industry has a long history, and still in all the heat exchanger in the dominant position.
Q:What is a jacketed heat exchanger?
In order to supplement the insufficient heat transfer surface, the tank can also be installed inside the kettle, and the jacketed heat exchanger is widely used for the heating and cooling of the reaction process.
Q:What is a shell and tube heat exchanger?
Shell and tube (also known as tube-type) heat exchanger is shell and tube heat exchanger mainly shell, tube bundle, tube plate and head and other components, the shell was round, with parallel tube bundles or spiral , Both ends of the tube bundle fixed to the tube plate.
Q:What is the classification of heat exchangers?
Applicable to different media, different conditions, different temperatures, different pressure heat exchanger, structural type is also different, the specific classification of heat exchangers are as follows:
