Design of gas monitoring system of coal bunker in coal preparation plant

  • 摘要: 针对传统的选煤厂煤仓瓦斯监控方法存在测量精度低、实时性差、成本高等问题,设计了基于模糊控制的选煤厂煤仓瓦斯监控系统。该系统将变频技术引入通风机控制中,当瓦斯浓度发生变化时,采用变频器对煤仓通风机转速进行调整:当瓦斯浓度较大时,控制通风机转速提升,增加通风量,保证瓦斯浓度不超标;反之则降低通风机转速,降低能耗,从而有效地实现煤仓瓦斯浓度的实时在线监控。实际应用结果表明,该系统可明显降低煤仓瓦斯浓度均值和波动,有效保证选煤厂煤仓安全。
    Abstract: In view of problems of low measurement accuracy, poor real-time performance and high cost of traditional gas monitoring system of coal bunker in coal preparation plant, gas monitoring system of coal bunker in coal preparation plant based on fuzzy control was designed. The system introduces frequency conversion technology into ventilator control when gas concentration changes, frequency converter is used to adjust rotation speed of ventilator in coal bunker: when the gas concentration is large, rotation speed is controlled to increase and ventilateel quantity is increased to ensure gas concentration does not exceed the standard; otherwise rotation speed is decreased to reduce energy consumption, thereby real-time online monitoring of gas concentration in the coal bunker is realized. The practical application results show that the system can significantly reduce mean and fluctuation of gas concentration in coal bunker, and effectively ensure safety of coal bunker in coal preparation plant.
