Saturator Integrated Lime Silo & Saturation Tank

## Product Overview
The Saturator Integrated Lime Silo is an all-in-one core equipment specially developed for hydrated lime storage and continuous saturated lime water preparation, widely deployed in water treatment and flue gas desulfurization systems. It integrates sealed lime powder storage, anti-bridging quantitative feeding, counter-current saturation dissolution, layered clarification and automatic sludge discharge into a single tank unit, replacing separate silos and mixing tanks to cut site footprint and construction costs drastically.

Conventional separate lime storage and mixing facilities suffer from severe dust leakage, frequent lime caking/bridging, unstable lime liquor concentration, heavy manual workload and messy sludge accumulation. Our Saturator tank adopts proprietary counter-current saturation technology to generate consistent clarified saturated calcium hydroxide solution round-the-clock for pH adjustment, water softening, heavy metal precipitation, phosphorus removal and flue gas neutralization. Horizontal and vertical configurations are available with customizable volumes ranging from 5m³ to 120m³ to fit various plant layouts.

## Working Principle
1. **Sealed Dust-Free Lime Storage**
Hydrated lime powder is delivered via pneumatic bulk truck conveying or manual bag feeding. The fully airtight tank body blocks external moisture to prevent lime damp agglomeration. A top pulse bag dust collector recycles all feeding dust, while radar level sensors monitor residual material and trigger low-lime auto-alarms. Vacuum relief valves balance internal pressure to avoid silo deformation.

2. **Anti-Bridging Uniform Discharging System**
The steep conical hopper at the tank bottom is equipped with aeration fluidization plates and high-frequency vibratory arch breakers to eliminate rat-holing and bridging. Variable-frequency star feeders deliver lime powder steadily and quantitatively to the saturation zone without blockages.

3. **Core Counter-Current Saturation Process**
Clean water flows upward through the lime bed from the tank bottom to achieve full dissolution under constant water head, forming stable saturated lime liquor. This design eliminates concentration fluctuations caused by unstable feeding rates, delivering uniform clarified lime water free of suspended solids.

4. **Layered Sedimentation & Automatic Sludge Removal**
Undissolved lime residues, sediment and impurities sink to the bottom sludge hopper. Automatic drain valves enable scheduled sludge discharge without frequent manual cleaning. Clear saturated lime water overflows from the middle clarification zone to downstream dosing pipelines, preventing pipeline clogging.

5. **Intelligent PLC Automatic Control**
The integrated control system interlocks water inlet valves, feeders, liquid level transmitters and online concentration monitors. It auto-regulates water supply and lime feeding to maintain saturated status, with automatic shutdown and fault alarms for low liquid level, material shortage and blockage. It supports seamless connection to plant DCS central control systems.

## Main Structural Components
1. **Integrated Tank Body**
- Standard material: Q235 carbon steel with internal epoxy anti-corrosion coating to resist alkaline corrosion; 304/316 stainless steel optional for highly corrosive working conditions
- Vertical / horizontal dual styles for low-height confined workshops
- Complete accessories: top manhole, safety platform, guardrails, vertical ladder and full sealing rubber gaskets

2. **Top Dust Removal Assembly**
Pulse bag dust collector with negative-pressure fan realizes zero dust emission during bulk feeding, fully complying with industrial environmental protection standards.

3. **Arch Breaking & Feeding Module**
Combined fluidization aeration + vibratory arch breaker + variable-frequency rotary feeder for stable, smooth lime discharging.

4. **Saturation Clarification & Sludge Discharge Zone**
Counter-current dissolution chamber, layered sedimentation area and centralized sludge hopper with automated drain outlets.

5. **Touch Screen PLC Control Cabinet**
Real-time monitoring of lime stock, water level, liquor concentration and equipment operating status; supports fault self-diagnosis, data logging and remote IoT monitoring.

## Core Competitive Advantages
1. **All-In-One Compact Layout, Small Footprint**
Combines storage, dissolution, clarification and sludge treatment in one tank, slashing civil engineering, pipeline and installation costs compared with split systems.
2. **Stable Saturated Lime Liquor Output**
Constant-head counter-current saturation guarantees consistent liquor concentration, avoiding unstable dosing results from manual mixing.
3. **Full Enclosed Dust-Free Operation**
Built-in dust recovery system eliminates lime dust pollution, improves workshop working conditions and meets strict emission regulations.
4. **Reliable Anti-Caking & Anti-Blocking Performance**
Multi-dimensional arch breaking and fluidization design thoroughly solves common silo bridging and discharge blockage issues.
5. **Low Maintenance & Unattended Continuous Operation**
Auto feeding, water replenishment and sludge draining minimize manual labor; centralized sludge hopper simplifies regular maintenance.
6. **High Customization Flexibility**
Customizable capacity, horizontal/vertical shape, electric heat tracing for cold anti-freezing, explosion-proof electrical parts and multi-silo parallel expansion solutions.

## Typical Application Scenarios
- Municipal tap water & wastewater treatment (pH adjustment, softening, heavy metal & phosphorus removal)
- Power plant flue gas desulfurization
- Chemical factory acidic wastewater neutralization
- Mine wastewater purification
- Industrial circulating water conditioning

## Optional Auxiliary Accessories
1. Online lime liquor concentration detector with automatic data recording
2. Electric heat tracing & insulation system for low-temperature anti-crystallization
3. IoT remote monitoring module for mobile/PC real-time equipment management
4. Automatic bulk lime pneumatic conveying system matching tank trucks
5. High-precision weighing module for real-time residual lime monitoring
6. Explosion-proof electrical components for hazardous production zones
