水封阻火泄爆装置水位传感器支管连接优化设计
|
摘要
为了解决低浓度瓦斯输送安全保障设备水封阻火泄爆装置在北方冬季使用中遇到的装置内水分无法完全排出,而导致的结冰损坏水位传感器等结构的问题,对其现有的支管连接方式进行了研究分析,提出了可将水分全部排出的优化设计方案。通过现场实践,实现了水封阻火泄爆装置在北方冬季调试及检修时不再受结冰损坏水位传感器的影响,可迅速恢复投用,保障煤矿安全生产。
In order to solve the low-concentration gas transmission safety protection equipment,the water seal fire-proof venting device can not completely discharge the water in the device encountered in the winter in the north,the resulting icing damage to the structure of the water level sensor.Research and analysis of its existing branch pipe connection methods,proposed an optimal design for all moisture removal,practice through the field,the realization of the water-sealed fire-proof and venting device were no longer affected by the ice-damaged water level sensor during the winter debugging and maintenance in the north,can be quickly restored to ensure the safe production of coal mines.
