Industrial blower: what it is, types, application

Blowers are equipment with a compressor. It is installed in technological lines to create excess pressure or vacuum. Industrial blowers supply a very strong flow of air or gas into the system. Such equipment differs in design. This affects its technological features. Let's consider the main types of industrial blowers.

Vortex blowers

Such equipment compresses the liquid by mechanical means, increasing its speed and pressure. Two vane rotors are installed in the system. They rotate in opposite directions with respect to each other so that the liquid moves into the blower.

Features of vortex blowers:

• The design of the mechanisms is compact and reliable.
• Installation of the equipment in the production system is convenient and easy.
• No vibrations occur during the operation of the device, the noise level is low.
• In the air streams do not get oil impurities, because it is not necessary to lubricate the parts of the mechanism.

Vortex-type blowers are used for aeration of various media. They are installed at treatment facilities, in food processing systems, for blowing in technological processes.

Compressor for water bodies

A compressor of vortex or screw type is installed in water bodies. It is necessary for saturating the liquid with oxygen. The equipment injects powerful air flows into the water, triggering the circulation of liquid and oxygen. Such systems come in two types:

• Piston units are suitable for large bodies of water. They are more powerful, but noisy.
• Diaphragm compressors are installed in small medium-sized ponds. They are compact and operate quietly.

Centrifugal blowers

In this system, the movement of the medium is set by centrifugal forces. They are generated by the rotation of the wheel, which accelerates the air from the center to the outer sides. When air enters at the ends of the blades, pressure is generated. The movement of the masses slows down and compression occurs in the circular diffuser. The air enters the return duct that directs the air to the next element of the unit.

Features of centrifugal blowers:

• Simple design that operates efficiently and for long periods of time.
• Minimal maintenance is required.
• These systems can be installed in harsh climates with high temperatures.
• The unit is small in size, but it gives high compression.
• There is an energy saving mode.

Centrifugal units are incorporated into cooling, combustion or drying systems. It is part of boiler ventilation design.

Rotary blowers

In these units, air is moved from the synchronized rotation of two rotors with multiple blades. These are located in the discharge cavity. They are driven by an asynchronous electric motor. The blades rotate towards each other and carry air flows. A filter is installed in the system. It cleans the working medium that passes into the system.

Features of rotary blowers:

• High performance with small dimensions.
• Modular design makes installation and maintenance of the equipment much easier.
• The system starts up quickly.
• Low energy consumption.
• No oil vapors get into the pumped medium.
• Rotors are virtually wear-free.
• The device is unpretentious to the conditions of use.

Rotary industrial blowers work like vacuum pumps. They are installed in wastewater treatment plants, in vacuum evaporation plants, in designs for air conditioning, in systems for filter washing.
