China New Design Heat Exchanger (ASME standard)
1. About Us
1). Our company was established in the 1950s, designed and manufactured the first stainless steel distillation column in China.
2). Our company can produce 6 full sets of equipment (including crushing section, liquefying and saccharification section, fermentation section, distillation section and DDGS section) in a month.
3). Among 16 production workshops, 3 workshops are for mechanic manufacture, 5 workshops are for manufacturing process, 8 workshops are for assembling & welding.
4). We own advanced machining equipment and product testing equipment.
2. Product Info
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.
3. New Process Info
1) Five-Column Three-Effect Distillation Process
Our company designs and manufactures latest Five-Column Three-Effect Distillation equipment. This new process is upgraded from 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 the heat to other 4 columns to achieve three-effect thermal coupling and energy-saving effects.
In terms of electricity efficiency, it can save 50% electricity and avoid the repairing of circulating pumps and also extend the working life of the re-boilers.
2)Double-Mash-Column Three-Effect Distillation Process
This process applies to the production of general-grade alcohol& fuel ethanol, and it was awarded Chinese national patent, it is the onlysuccessfulapplication of 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 40% steam.
4. Designed capability
1). We own Design License of Special Equipment D1 & D2 Class; Manufacture License of Special Equipment A2 Class; Design License of Special Equipment GC Class.
2). Our company achieves more than 20 patent certificates on distillation, DDGS, and other fields.
3). Our company owns ASME certification, ISO 9001 Quality System Certification, ISO 14001 Environmental Management System Certification & GB/T28001 Occupational Health and Safety Management System Certification.
