Ejector

An ejector is a static device that uses a high-pressure driving fluid to entrain and transport a low-pressure fluid, without any moving parts. Its simple structure and low maintenance make it widely used in various industrial processes, including transport and mixing, vacuum generation, and thermal energy recovery.

Main Components:

Nozzle: Accelerates the high-pressure driving fluid (e.g., steam or gas) into a high-velocity jet.

Mixing Chamber: The high-speed jet entrains the low-pressure suction fluid, and kinetic energy is transferred to the mixture.

Diffuser: The mixed flow decelerates, converting kinetic energy into pressure, thus increasing outlet pressure.

Key Advantages:

Simple Design: No moving parts, low failure rate, minimal maintenance.

Versatile Media Handling: Suitable for gases, liquids, steam, and even particle-laden fluids.

Corrosion Resistance: Material options available for corrosive media.

Oil-Free Operation: Ideal for clean industries like food and pharmaceuticals.

Leak-Free: No rotating elements, reducing leakage risk.

Typical Applications:

Steam Jet Air Ejectors in power plants for removing non-condensable gases.

Steam heating and mixing in large storage tanks.

Vacuum distillation systems in chemical plants for maintaining vacuum and removing by-products.

Corrosive gas handling in process industries.

Blast furnace gas transport to reheating furnaces in steel plants.

Vacuum degassing of molten steel.

Freeze-drying and concentration processes.
