Vacuum cleaning system and industrial dust removal equipment, Windwick fan

In vacuum cleaning systems and industrial dust removal equipment, the cast aluminum high-pressure blower (usually referring to high-pressure centrifugal fans or multi-stage turbine fans) plays the role of the "system heart". Its working principle and selection logic are fundamentally different from the application of blow drying, with the core being the generation of negative pressure and the maintenance of airflow to carry dust.

The following is a detailed analysis of the application.

1、 Main working principle

In these two types of devices, the working principle of the fan is to forcefully discharge the air inside the system through the high-speed rotating impeller, creating a negative pressure (vacuum degree) relative to the atmosphere in the suction port or filter cartridge cavity.

1. Generate negative pressure (vacuum degree):

·The fan is installed on the clean air side of the dust collector (i.e. after the filter element). When the fan is working, it continuously extracts filtered clean air, causing a decrease in pressure inside the sealed dust collector box.

·According to the principles of fluid mechanics, external dusty air will automatically flow into the interior of the box through the path with the least resistance, namely the suction port/suction arm pipeline dust collector filter element, under the drive of atmospheric pressure, with a pressure difference.

2. Establish a conveying airflow:

·This continuous airflow from the suction port to the fan provides conveying power for dust particles. The airflow velocity must be high enough to ensure that dust remains suspended in the pipeline and is carried away, without settling at the bottom of the horizontal pipeline.

3. Core difference: Vacuum suction vs. dust removal

·Vacuum cleaning system: usually mobile or ducted, the fan directly generates high negative pressure for capturing and transporting materials (such as debris, particles). The key is to overcome the resistance of the suction nozzle, hose, and separator to achieve effective picking.

·Industrial dust removal equipment: usually a fixed dust collector, the fan mainly overcomes the filtering resistance of the filter element while maintaining the negative pressure of the system. The air volume should ensure that the filtering air speed is within a reasonable range to achieve effective dust cleaning and filtration.

2、 Key performance requirements and selection parameters

The core of selection is to balance the relationship between "suction" (negative pressure/vacuum degree) and "wind" (air volume).

Parameter Importance and Requirements Estimation and Range Reference

1. Key parameters of air volume (Q). Determine the effective coverage range of the dust collection system, the wind speed required to maintain dust deposition in the pipeline, and the filtration wind speed of the dust collector. Insufficient air flow prevents suction from reaching distant areas, causing dust to settle. It is determined by the conveying wind speed and pipeline area or the filtering wind speed and filtering area. This is the primary calculation parameter. The range is extremely wide, from a few m ³/min for mobile vacuum cleaners to thousands of m ³/min for large-scale dust removal.

2. Key parameters of pressure (P) or vacuum degree (Δ P). The pressure here refers to the total system pressure loss that the fan needs to overcome, manifested as the vacuum degree (negative pressure) at the inlet end. It must be sufficient to overcome: local resistance at the suction port+frictional resistance along the pipeline+resistance of the dust collector body (the core is the resistance of the filter material). The total resistance of the system is usually between 1.5-7 kPa (approximately 150-700 mmH ₂ O, or 6-28 inches of water column). Among them: • Initial resistance of filter element:~500-1000 Pa • Resistance after dust accumulation of filter element: can increase by 1000-2000 Pa • Pipeline resistance: calculated based on length, elbow, and wind speed • Suction resistance: depends on the design.

3. Power (kW) derived parameters. Determined by the required air volume and total system pressure. From kilowatts of household vacuum cleaners to hundreds of kilowatts of industrial large-scale dust collectors.

4. Material and characteristics: Cast aluminum shell: lightweight, suitable for general industrial dust. If the dust is abrasive (such as grinding wheel dust), attention should be paid to the wear-resistant treatment of the impeller (such as spraying a hardened layer). If it is flammable and explosive dust, it is strictly prohibited to use cast aluminum fans (which may generate sparks), and explosion-proof types (such as copper impellers or all aluminum structures) must be selected.
