Dry Powder Dosing Systems Dry Powder Dosing Systems Wholesale - QILEE

Product Overview

- QILEE Dry Powder Dosing System (Lime Powder Dosing System) is a fully automated, closed-loop solution for turning dry quicklime into a controlled lime slurry and dosing it into wastewater treatment lines.

- The process covers six core steps: powder conveying & storage, level monitoring & quantitative feeding, sealed conveying, dissolution & preparation, slag-water separation, and metered dosing.

- Models are modular and scalable (QLDC-5 to QLDC-100) with dosing capacities from ~50 to 5,000+ kg/hr (model-dependent) and optional materials (carbon steel or 304 SS) and winterization features.

Product Features

- Dust-free, fully sealed pneumatic conveying with >99.5% dust removal efficiency and top-mounted pulse dust collector.

- Anti-clogging design for cohesive powders: fluidization air cushions, air hammers, activated hopper and frequency-controlled screw conveyors.

- Automated dissolution with agitator and concentration sensor (typical slurry 5–10% W/V), built-in slag filter and automatic slag discharge.

- Integrated pipeline automatic cleaning, buffer tanking and high-precision metering pumps linked to flowmeters and pH sensors for feedback dosing.

- Intelligent control: PLC + HMI, MODBUS remote monitoring/control and adjustable parameters via frequency conversion.

Product Value

- Reduces occupational exposure and labor intensity by eliminating dust and manual handling.

- Improves chemical dosing accuracy and process stability through closed-loop monitoring (level, concentration, flow, pH) — leading to more consistent treatment results and chemical savings.

- Lowers maintenance and downtime risk with anti-clogging measures, automatic cleaning and robust materials for long service life (>10 years).

- Environmentally compliant solution that minimizes emissions and secondary pollution.

Product Advantages

(vs. peers)

- True end-to-end, integrated system (storage, metering, conveying, dissolution, separation, dosing and cleaning) — fewer interfaces and simpler operation.

- Industry-grade sealing and corrosion/high-temperature resistant components for reliable operation in harsh or humid environments.

- Proven anti-caking and anti-clog technologies specifically for problematic powders like quicklime.

- Flexible, scalable model range and customizable options (insulation/heating, tank sizes, material choices) to match plant scale and climate.

- Backed by QILEE’s manufacturing controls and 20 years of process design experience with global deployments and responsive service/support.

Application Scenarios

- Municipal and industrial wastewater treatment for pH adjustment, neutralization, phosphorus precipitation and general chemical dosing.

- Industrial effluent treatment, water reuse and process water preparation in chemical, mining, food, textile and metal-processing plants.

- Retrofit or upgrade projects and containerized/plug-and-play treatment systems requiring rapid deployment.

- Cold-climate installations (with optional heating/insulation) and any site needing dust-free, automated handling of reactive or dusty dry powders.
