摘要
为了提高环境质量,火电企业要求煤场封闭,但随之而来带来了储煤安全性问题,煤在氧气、温湿度、存储时间满足条件下慢慢地从表面氧化,排放出多种可燃气体包括CO、CH4等。现场人员长时间处在这样工作环境下,极易造成身体伤害,严重时甚至会发生气体中毒窒息、人员伤亡事故。因此进行煤场气体检测,实时掌握煤场内部各种有毒可燃气体浓度,进行超限报警,及时进行通风控制、人员疏散,可避免爆炸、人员伤亡的恶性事故发生。
In order to improve the quality of environment, coal yard closed thermal power enterprise requirements, security issues, but follow the storing coal coal under the condition of oxygen, temperature a nd humidity and storage time meet slowly from surface oxidation, emissions from a variety of combustible gas including CO, CH4, etc. The site operators stay in such a working environment for a long time, causing physical injury, and can even suffocate and suffocate personal accidents. Real time control of the coal yard internal detection of coal gas, therefore, a variety of toxic, combustible gas concentration to transfinite alarm, in a timely manner through risk control system, personnel evacuation, can avoid explosion, casualties of the malignant accident.
