Membrane deaerator, also called normal temperature energy-saving membrane deaerator, is an advanced boiler deaeration method in China. Compared with the traditional deaeration methods currently used in China (thermal deaeration, analytical deaeration, sponge iron deaeration, vacuum Deoxygenation, resin deoxygenation, etc.). These traditional deaeration technologies have certain limitations. Some of them consume high energy, and some impurities harmful to the boiler are brought into the water after deaeration, causing secondary corrosion and pollution of the boiler. This makes the traditional deaeration methods in the industry It is difficult for the boiler to achieve the expected oxygen removal indicators when used alone. Membrane deoxygenation: Through the principle of complete physical degassing, combining the advantages of vacuum and analytical deoxygenation, the ultimate separation of gas and liquid is achieved through highly hydrophobic hollow fiber membranes, and the deoxygenation effect exceeds the "Industrial Boiler Water Quality Standard". At present, well-known enterprises such as Baosteel have begun to gradually use our company's membrane oxygen removal products.
The advantage of this type of deaerator compared with traditional deaerators is that
It operates at room temperature without consuming steam, which greatly saves energy
It is a purely physical method, does not increase the salt content in the water, and has no secondary pollution. Problem
The equipment is small in size and light in weight, and can be arranged in any position, greatly saving infrastructure investment
The operating cost is ultra-low, except for consuming a small amount of purge gas and electricity, it does not consume any other substances
Can remove oxygen and carbon dioxide from water
Fully automatic control, suitable for long-term operation, insensitive to large changes in load
Long service life, the membrane contactor has a hydrophobic performance of at least 10 years
Low-position layout, There is no cavitation problem in the water pump, which greatly extends the life of the water pump and reduces the power consumption of the water pump
Capacity expansion can be easily achieved through parallel modules
() Limit removal of dissolved oxygen in water can be easily achieved through series modules
/> It can fully utilize the low-temperature waste heat of clean fuel boilers and even exhaust smoke condensation
Suitable for various high, medium and low pressure boilers
Membrane deaerators have the advantages of energy saving, environmental protection, and Due to its high efficiency, as membrane technology becomes increasingly mature, it is an inevitable trend to replace conventional deaerators. Membrane deaerators have irreplaceable advantages for water replenishment in hot wells of gas condensing boilers, marine boilers, oil field steam injection boilers and power station condensers.
