Embodiment Construction
[0013] A double-layer automatic water discharger for gas pumping and discharging, including a gas-water separator and a double-layer water discharger; such as figure 1 As shown, the gas-water separator includes a separator housing 1, a three-way valve 5 is arranged above the separator housing, the upper port of the three-way valve is connected to the drainage pipe 5, and the side port of the three-way valve is connected to a fitting. Air pipe 4, both ends of the air distribution pipe 4 are provided with concave air distribution ports, and a table tennis ball 3 is arranged in the air distribution pipe, and the diameter of the table tennis ball 3 is larger than the air distribution port and smaller than the gas distribution pipe diameter; 2. An outlet 7 is provided on the other side, and the inlet 2 is higher than the outlet 7. The inlet is connected to the borehole, and the gas-water mixture pouring out of the borehole is poured into the separator shell 1. After precipitation a...

The invention relates to a coal mine gas drainage control device, in particular to a double-layer automatic water release device for gas drainage. Solve the problem that the water release device is easily affected by the nozzle hole and cannot discharge water normally during the existing coal mine underground gas drainage process, including the gas-water separator and double-layer water release device; by using the gas-water separator and double-layer automatic water release device, It effectively prevents water accumulation in the pipeline and ensures the safe and stable operation of the drainage system. At the same time, it is necessary to prevent gas overrun accidents caused by drilling holes caused by personnel releasing water and failure of water release devices. The waste of personnel is reduced and the work efficiency is improved.
Description
technical field [0001] The invention relates to a coal mine gas drainage and treatment device, in particular to a double-layer automatic water discharger for gas drainage. Background technique [0002] In the process of gas drainage and drilling of the 1000-meter drilling rig, due to many drilling footage and multiple branches, it is easy to cause drilling nozzle holes. When drilling nozzle holes, water and gas directly enter the water discharger. When the personnel do not discharge water in time When the water is discharged, the water easily enters the drainage pipeline, which affects the operation of the drainage system; when the personnel release the water, the drainage valve of the water release device must be closed, which may easily cause the gas in the hole to overflow and cause the site to exceed the limit. At the same time, it is necessary to arrange a special person to carry out the water discharge operation on site, resulting in a waste of personnel. SUMMARY OF ...
