Operating Principle:
Fluidized bed activated carbon gas-solid jet unit, powered by a centrifugal blower (air compressor, Roots blower) as the gas source, utilizing the gas-solid two-phase flow principle, combining fluidization technology, jet technology, and pressure difference principle. It employs an electric rotating feeder as the feeding device to send the material into the material-gas mixing chamber. While the material is fluidized in the mixing chamber, the material is propelled into the acceleration chamber by the high-speed air stream generated by the double-looped nozzle. It enters the conveying pipeline as a suspended flow and is conveyed into the receiving bin along the pipeline by utilizing the air pressure difference. Material-gas separation occurs, and after being filtered by a bag dust collector, the gas is released into the atmosphere.
Features:
1. Cost-effective investment, low operating costs, and significant energy savings
A low-pressure continuous conveying system composed of a gas-solid activated carbon lime spray nozzle not only reflects its cost-effectiveness in the construction investment but also boasts low operating costs. Due to the absence of in/out material and exhaust valves, as well as lack of wear-and-tear parts, operating expenses are minimized. Additionally, using a low-pressure conveying system saves approximately 30% in energy consumption compared to an air compressor system.
2. User-friendly
The equipment's main control only includes an electrically-powered rotary feeder and an intake valve, so the main control operation is simply "start" or "shutdown." The equipment operation only requires monitoring without the need for manual attendance. Due to the simplicity of the continuous pump process system, the control system configured is also correspondingly simple. According to the system configuration, even if a PLC control system is used, in the event of a fault, an alarm system is in place, and manual control is also possible, which does not affect the normal operation of the system.
3. Low equipment and pipeline wear, with a long service life
Due to low-pressure conveying, the flow velocity within the equipment and ash conveying pipes is low, maintaining a constant concentration. As a result, 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, the equipment is convenient and flexible for system layout, fully meeting the engineering requirements.
5. No stringent quality requirements for the gas source.
Continuous pump-powered air source, typically utilizing centrifugal fans or Roots blowers and compressors; no air purification system is required. The system design dictates specific requirements for air volume and pressure. Compressed air from a pressure station can also be used as needed.
6. High system reliability
The gas-solid activated carbon lime spray nozzle is powered by a centrifugal blower or a Roots blower and a compressor as the source of motive gas. The high performance of the blower ensures the reliability of the system's operation.
② A pneumatic conveying system composed of an air-solid activated carbon lime jetter can utilize a configuration with two ash bins sharing one pump, under the condition of permissible ash quantity on site. Generally, this results in a minimal number of equipment, making the entire system simple and reliable.
③ The gas-solid activated carbon lime spray nozzle maintains a stable gas-to-material ratio, with no impact load and no frequent operation of valves as in conventional pneumatic conveying processes, significantly reducing equipment failure rates.
