I. The Principle and Features of Quicklime Sprayer:

Principle:

Hydraulic Solid-Air Jet Injector, powered by a centrifugal blower (compressor, Roots blower), utilizes the principle of gas-solid two-phase flow. It combines fluidization technology, jet technology, and pressure difference principle. The electrically powered rotating feeder serves as the feeding device, conveying materials into the material-air mixing chamber. As the materials fluidize in the mixing chamber, a high-speed airflow generated by the double-looped nozzle propels the materials into an acceleration chamber, entering the conveying pipeline as a suspended flow. The materials are then propelled through the pipeline into the receiving bin using the air pressure difference. Material-gas separation occurs, and after passing through a bag dust collector, the gas is released into the atmosphere.

Features:

1. Cost-effective investment, low operational costs, and significant energy savings

A low-pressure continuous conveying system composed of lime hydrate gas-solid jet nozzles not only reflects its cost-effectiveness in terms of construction investment but also boasts low operating costs. Due to the absence of infeed and outfeed valves, as well as no fragile parts, the operating expenses are minimized. Additionally, using low-pressure conveying saves approximately 30% of energy compared to compressed air system conveying.

2. Easy to operate

The equipment's main body control features only an electrically-powered rotating feeder and an inlet valve, so the main body control requires only "start" or "shutdown" operations. The equipment operation only necessitates monitoring without the need for constant human attendance. Due to the simplicity of the continuous pump process system, the configured control system is also correspondingly simple. According to the system configuration, even with a PLC control system, in the event of a fault, an alarm system is in place, allowing manual control without affecting the normal operation of the system.

3. Equipment and pipelines have minimal wear and extended lifespan.

Due to the use of low-pressure conveying, the flow velocity within the equipment and ash conveying pipes is low, resulting in a constant concentration of material being transported. Consequently, the system's equipment and pipelines experience minimal wear and have a long service life.

4. System layout is convenient and flexible.

Due to its compact size and low installation height, this equipment offers convenient and flexible system layout, fully meeting engineering requirements.

5. Quality requirements for the gas source are not stringent.

Continuous pump-powered air source, typically using centrifugal fans or Roots blowers and compressors, without the need for an air purification system. The system design only requires specific air volume and pressure. Compressed air from a pressure station can also be used as needed.

6. High system reliability

① The air-solids jetting of quicklime uses centrifugal blowers or Roots blowers and compressors as the power source for the gas. The high performance of the blowers ensures the reliability of the system's operation.

② The air-powered conveying system composed of lime gas-solid jet nozzles can adopt a configuration where two ash bins share one pump, under the condition of allowable ash quantity on-site. Typically, this results in a fewer number of equipment, making the entire system simple and reliable.

③ The lime hydrate gas-solid jetting feeder maintains a stable gas-to-solid ratio, with no impact load and no frequent operation of valves as in conventional pneumatic conveying processes, significantly reducing the equipment failure rate.
