Reliable Dry Powder Dosing Systems Company

Product Overview

- Fully automated, closed-loop dry lime powder dosing system for preparing and metering lime slurry into wastewater streams.

- Core process: powder conveying & storage, level monitoring & quantitative feeding, sealed conveying, dissolution & preparation, slag-water separation, and metered dosing.

- Includes storage silo(s), pneumatic conveying, frequency‑controlled screw conveyor, dissolution tank with agitator and concentration sensor, slag filter, buffer tank, high‑precision metering pump, and PLC + HMI control.

- Modular models (QLDC-5 to QLDC-100) cover small municipal plants to large industrial/wastewater treatment facilities; many parameters customizable.

Product Features

- Dust-free, fully sealed pneumatic conveying from truck unloading to silo; top-mounted dust collector with >99.5% efficiency.

- Anti-clogging design: fluidization air cushions, air hammers and activated hopper to handle poor‑flowing/caking powders like quicklime.

- Automated slurry preparation: concentration sensor and automatic adjustment of powder/water to maintain target slurry (typ. 5–10% W/V).

- Integrated slag‑water separation and automatic pipeline cleaning to prevent blockages and simplify maintenance.

- Intelligent control: PLC + HMI, remote monitoring via MODBUS, and frequency conversion for continuously adjustable dosing.

Product Value

- Improves safety and environmental compliance by eliminating dust emissions and minimizing operator exposure.

- Reduces labor and manual handling through full automation, lowering operating costs.

- Delivers precise, adaptive dosing tied to flowmeters and pH sensors, improving treatment effectiveness and chemical use efficiency.

- Lowers downtime and maintenance needs via anti‑clogging measures and automatic cleaning; robust construction supports long service life (>10 years).

- Flexible sizing and customization enable cost‑effective deployment across a wide range of treatment scales and climates.

Product Advantages

- True closed‑loop, end‑to‑end solution (unloading → dosing) that minimizes secondary pollution and manual intervention.

- High reliability in harsh conditions: high‑tightness seals, high‑temp/corrosion‑resistant sealing parts, optional 304 stainless steel, and laser‑welded pressure‑grade vessels.

- Precise, repeatable dosing through frequency‑controlled conveyors and high‑precision metering pumps integrated with sensor feedback.

- Proven anti‑blocking technologies specifically for quicklime and other poor‑flow powders, reducing process interruptions.

- Modular, configurable models with optional insulation/heating for cold regions and remote control for centralized management.

Application Scenarios

- Municipal wastewater treatment plants for pH adjustment, phosphorus precipitation and sludge conditioning.

- Industrial effluent treatment (chemical, mining, metal finishing, food & beverage) requiring lime dosing for neutralization or contaminant removal.

- Water treatment facilities needing controlled lime slurry preparation and dosing.

- Projects with strict dust control and occupational safety requirements, or where reduced labor is needed.

- Cold‑climate installations (with optional heating/insulation) and facilities of various scales—from small plants to large industrial systems.
