PROJECT SUPPLY, INSTALLATION OF AIR DRYER FOR KVF FERTILIZER FACTORY
SUPPLY, INSTALL THE AIR DRYER FOR KVF PROJECT – KOREA FERTILIZER CO., LTD – VIET
What is an air dryer? Working principle of air dryer
The air dryer is an intermediate heat exchange device, where the process of absorbing heat from a hot source (steam, exhaust fumes, hot gas, …) and heating the air (fresh air) from ambient temperature takes place. up to 90-130˚C. Hot fresh air, after leaving the air dryer, is used to dry, dry or raise the temperature of raw materials and fuel before being mixed and produced.
The air dryer is an important and indispensable device in the heating system.
Air dryers are widely used in large factories, especially those that use large heat sources for mixing, drying, cleaning, etc., such as steel plants, fertilizers, lubricants, chemicals. , animal feed, cement…
Depending on the design purpose, the air dryer has many different names such as:
Air Dryer
Waste heat recovery unit
Heat exchanger
Air heater
The feed air dryer…
For example, the operating principle of a gas dryer uses a hot source of heat from the exhaust gas after burning gas.
Actual pictures of some air dryers
Current status of air dryer at KVF plant (Han Viet fertilizer)
The air dryer at KVF plant (Han Viet Fertilizer) is used continuously for a long time, the status quo:
The radiator impeller on the pipe of the air dryer is rotten, broken
Radiator pipes catch deposits, many pipes are rusty, rotten, broken
Many heatpipes have broken welds and fall from the assembly location
The actual used capacity is only about 40% compared to the design
Hai Chuong supplied and installed a new air dryer for KVF project (Han Viet Fertilizer)
Based on the current situation of the air dryer at the KVF plant (Han Viet Fertilizer), Hai Chuong Trading and Technical Services Co., Ltd. has surveyed, discussed with the company, jointly proposed the design and agreed on the technical plan. The technical specifications for the improved air dryer with the factory are as follows:
Technical options
Air divider, air collection: SUS316
Box frame: SUS304
Pipe: SUS316 – fins SUS304
Flange and flanged pipe: SUS304
Wings and tubes are plated, coated with Titanium, resistant to wear and increased heat transfer coefficient.
Thermal and mechanical designs are calculated in detail, carefully and reliably, simulated on copyrighted design software
Design standards:
ISO 9001 – 2008
NATA (factory inspection certificate of mechanical inspection quality – Mechanical Testing).
ASME – U (ASME U Stamp production certificate for Boiler and Pressure Vessel) – Certificate of American organization
ASME – U2 (ASME U2 Stamp production certificate for Boiler and Pressure Vessel) – Certificate of American organization
National Board of Boiler & Pressure Vessel Inspector R Stamp – NBIC R-stamp. (Repair Certificate for Boiler and Pressure Vessel) – Certificate of Australian organization
Great heat exchanger efficiency
Material SUS316 (most of the main parts), SUS304 with heat fins. Wing thickness is only 0.3mm
Tubes and fins are coated with Titanium coating, which helps prevent wear (from hard dust), and increases heat exchange efficiency.
