The specific embodiment
Below in conjunction with embodiment the utility model is further specified.But be not limited thereto.
Embodiment 1:
A kind of gas pumping crossheading drilling holes at the drilling yard moisture trap, the deslagging integrated apparatus that discharges water comprise moisture trap and tailrace, and structure is shown in Fig. 1-4.
Moisture trap tank body 4 is the steel circular cylindrical container of Φ 273mm; High 0.6m; On the chamber wall symmetrical equidistance equably annular be provided with 4 borings and connect the mouths of pipe 2, these 4 borings connect the mouths of pipe 2 and are the Φ 50mm mouth of pipe that is provided with valve, these 4 borings connect the mouths of pipe 2 and connect with crossheading drill site internal drilling 13 through the rubber hose 18 that are provided with steel-wire carcass in the tube wall; These 4 boring interfaces can be communicated with the internal drilling of 4 crossheading drill sites simultaneously respectively; Also can only connect crossheading drill site internal drilling 13 (as shown in Figure 3) as required, perhaps connect 3 crossheading drill sites internal drilling 13 (as shown in Figure 4), close remaining boring interface.Moisture trap tank body 4 tops have 1 Φ 108mm mouth of pipe to connect gas pumping pipe 16 as Device in Gas extract opening 1; The moisture trap top is provided with the snap joint 6 of 1 Φ 10mm, and the container bottom is provided with 1 delivery port 3 that the Φ 50mm of valve is housed; Communicate in two long 0.05m of welding on the chamber wall, Φ 2mm copper pipe and the container, these two copper pipes laterally arrange between the upper and lower apart from 0.4 meter, and plumbers shed connection transparent hose is as liquid level observation tube 7; Φ 273mm joint of container bottom welding, as slag-drip opening 5, normal operating conditions lower contact 5-1 goes up and connects a Φ 273mm chassis 5-2 sealing, and anti-heads is regularly opened chassis 5-2 and is carried out deslagging.
Tailrace tank body 8 is a Φ 315mm steel pipe; The water inlet 9 that tank body 8 one end tops are welded with Φ 50mm is communicated to the delivery port 3 of moisture trap through water pipe 17; The joint that has ball valve 10 that 1 Φ 10mm is arranged at water inlet 9 one face down bondings; This joint 10 is communicated to the joint 6 at moisture trap top as the gas outlet through the high pressure resistant sebific duct 15 of Φ 10mm, is provided with air intake valve 11 at tailrace tank body 8 other end tops, and the bottom is provided with dewatering outlet and valve 12.
Said moisture trap and tailrace all place back production crossheading field on the ground, and the volume of tailrace is 3 times of moisture trap volume.The water pipe 17 that is communicated with moisture trap and tailrace is the rubber hose that are provided with steel-wire carcass in the tube wall, and this flexible pipe maximum is born the negative pressure (Jing County, Hebei province hippocampus sebific duct factory product) of 80Kpa.
The course of work and principle are following:
The connection moisture trap is installed at crossheading drill site mash gas pumping drilling place; When water level reaches 1/3 in the liquid level observation tube of moisture trap; Close the ball valve of tailrace water inlet 9 valves and joint 10, open the Draw off valve 12 of tailrace air intake valve 11 and tailrace, discharge water.Discharge water finish after, close tailrace air intake valve 11 and Draw off valve 12 again, open tailrace water inlet 9 valves and gas outlet 10 valves.The air water of extraction borehole is incorporated into air water speed slows down in the eliminator; Device in Gas is under negative pressure state; Take away from the gas pumping pipe 16 on top; Boring water flows to moisture trap bottom, and moisture trap and tailrace are connected to form communicating pipe through snap joint 6 and the high-pressure rubber pipe 15 that has 10 of air outlet adapters of ball valve, so the water in the moisture trap is more prone to enter into tailrace through delivery port 3.Tailrace forms negative pressure water and is difficult for flowing out when discharging water in the container, therefore add an air intake valve 11 at the tailrace top, when discharging water, opens air intake valve 11, eliminates the negative pressure state in the container, makes water be more prone to flow out.
Present embodiment uses in the 1703 eastern coal-face crossheading drill sites in Dezhou City official Zhao colliery, Shandong Province; Be used for that gas pumping crossheading drilling holes at the drilling yard discharges water, deslagging 3 months; The problem of boring water slug extraction pipeline does not take place, and face gas extraction rate on average reaches 55%.And use the automatic tailrace of traditional gas pumping pipeline negative pressure, and will overhaul 1 time in average per 2 days, influence the improvement of gas, face gas extraction rate average 40%.Therefore, use the gas pumping crossheading drilling holes at the drilling yard moisture trap of the utility model, the deslagging integrated apparatus that discharges water (the full-automatic overflow device of high-order drill site) to compare than the automatic tailrace of traditional gas pumping pipeline negative pressure, the extraction rate has improved 15%.
