Detailed Product Overview

The ESP Ash Silo Rotary Valve, also known as ESP rotary airlock feeder, is core auxiliary equipment matching electrostatic precipitator ash silos in thermal power plants and industrial flue gas dust removal systems. Different from ordinary rotary valves, it is precisely optimized for ultra-fine, dry and easy-flowing ESP fly ash. The tight-tolerance rotor and housing structure achieves reliable airtight isolation between the negative-pressure ash silo and positive-pressure conveying pipeline, avoiding pressure imbalance that affects dust removal efficiency.

Adopting wear-resistant and anti-fine-dust blocking design, the valve body is processed with precision sealing and anti-adhesion treatment, which prevents fine ash from entering the bearing chamber and causing abrasion or jamming. Equipped with stable variable-speed electric drive, it realizes adjustable and uniform ash discharge volume, matching the operating load of ESP systems. Compact structure, fully sealed design and low failure rate make it the ideal long-term operation solution for ESP ash silo discharge systems.

Core Product Advantages

Professional ESP Fine Ash Adaptation: Optimized rotor gap and anti-blocking structure, specially designed for ultra-fine ESP fly ash, solving common problems such as fine ash leakage and material bridging.
Excellent Negative Pressure Airlock Performance: Precise machining sealing effectively isolates ash silo negative pressure, prevents outside air infiltration, and maintains stable ESP dust removal efficiency.
Anti-wear & Anti-adhesion: Wear-resistant structural design and surface treatment avoid fine ash adhesion and component abrasion, adapting to long-term continuous dry ash discharging.
Stable & Adjustable Discharging: Variable-speed drive supports flexible adjustment of ash discharge capacity, realizing uniform and quantitative feeding without surge flow.
Low Failure & Easy Maintenance: Fully sealed protective structure prevents dust contamination of transmission parts, reduces downtime and simplifies daily maintenance work.

Application Scope

Mainly used for electrostatic precipitator (ESP) ash silo discharge, power plant fly ash handling, industrial flue gas dust removal systems, dry ash storage silo discharging, and pneumatic conveying systems. It is exclusively suitable for continuous and stable discharge and air lock isolation of dry fine fly ash collected by ESP dust collectors.
