摘要:为了提高皮带转载点喷雾的喷射距离、覆盖面积、雾化效果,降低生产成本消耗,我矿认真研究ZPC127型矿用触控自动洒水降尘喷雾装置的工作原理,在不增加使用难度的前提下,本着方便、經济、便捷的方针,增大了喷雾喷头容量,喷头内部形成雾化腔,雾化容腔可以使压风和压水更好的混合,同时还对混合体有加压和蓄能作用,真正做到了无人值守、自动喷雾、连续工作,解决了ZPC127型矿用触控自动洒水降尘喷雾诸多不足,,大大降低了井下空气中的粉尘浓度,较好地消除了粉尘隐患,进而保障职工身体健康,创造良好的生产作业环境。
Abstract: In order to improve the injection distance, coverage area, atomization effect of the belt reprinting point spray, and reduce the cost of production, the mine carefully studies the working principle of the ZPC 127 mine automatic sprinkler spray device. Without increasing the difficulty of use, in line with the principle of convenience, economy, and convenience, the capacity of spray heads has been increased, and fog cavities have formed inside the spray heads. Fogging cavities can make better mixing of pressurized wind and pressurized water, and at the same time they also have pressure and energy storage effects on mixtures. It has truly achieved unmanned, automatic spraying, and continuous work, and has solved many deficiencies in the automatic sprinkling of water and dust spray for the ZPC 127 mine. It has greatly reduced the concentration of dust in the underground air, and has better eliminated the hidden dangers of dust, thus ensuring the health of employees and creating a good working environment.

煤尘以沉积堆积和悬浮两种状态存在,具有极大的危害性,其危害主要有:一是污染井下空气,使工作环境恶劣,不利于安全作业;二是悬浮状态的煤尘,特别是直径在0.2~10μm的游离状尘粒,可以被人体直接吸入气管、支气管、肺泡,瘀滞呼吸道,引起呼吸道炎症,严重时形成煤矽肺病,造成病人呼吸苦难,甚至死亡;三是煤尘一般具有爆炸性,当煤尘浓度达到下限30~50mg/m3,上限达到1000~2000mg/m3,热源温度达到610~1050℃,氧含量不低于18%时,会发生煤尘爆炸事故,造成矿毁人亡;四是瓦斯爆炸冲击波,扬起堆积煤尘,引起煤尘爆炸,使瓦斯事故进一步扩大。由此可见,煤尘是煤炭生产过程中的一项重大安全生产隐患,严重威胁井下员工生命安全和矿井安全。……
