A kind of colliery punching gas separator
Technical field
The utility model relates to a kind of gas-liquid separation device, is specially a kind of colliery punching gas separator.
Background technology
Along with coal mining difficulty is increasing, Gas Outburst problem is also more and more serious, and for head it off, present stage, ideal method adopted punching technology exactly.Boring after gas extraction hole, by injecting water under high pressure, inside, coal seam is being washed into cavity, effective like this bore diameter that increased, has strengthened gas permeability of coal seam, is conducive to gas and discharges.But, in punch process, can produce a large amount of things such as gas and water and cinder, gas and water, cinder etc. mix, and are not easy to the collection discharge of methane gas.
Utility model content
The purpose of this utility model is just to provide a kind of colliery punching gas separator, and it can separate with water, cinder fluid-mixing the gas producing in punch process, then collects.
For achieving the above object, the technical solution of the utility model is: a kind of colliery punching gas separator, be provided with a separator box, the top of separator box is provided with separation chamber, and a side of separation chamber is provided with fluid inlet, the bottom of opposite side is provided with slag-drip opening, the top of separation chamber is provided with the gas drainage under suction mouth being connected with negative tube, and described slag-drip opening place is provided with baffle plate, and baffle plate is hinged on separator box, the bottom of baffle plate is connected with flexible check apron, and baffle plate and flexible check apron block slag-drip opening jointly.
Described separation chamber forms with horizontal segment by vertical section that is interconnected, horizontal segment is connected to the bottom of vertical section, described gas drainage under suction mouth and fluid inlet are arranged on vertical section above, and slag-drip opening is arranged on horizontal segment, and the bottom surface of separation chamber is made up of the inclined-plane of two different gradients.
Beneficial effect: the utility model is received into the gas producing in punch process in separator box together with water, cinder fluid-mixing, has realized separating of gas and water, cinder.Separation chamber adopts two-stage structure, is convenient to the separation of methane gas.At the slag-drip opening place of separation chamber, baffle plate and flexible check apron are set, its can according to fluid flow number carry out self adaptation and regulate the size of slag-drip opening, play the effect that prevents gas leakage, improve separating effect.

Detailed description of the invention
As shown in Figure 1, a kind of colliery punching gas separator, be provided with a separator box 4, the top of separator box 4 is provided with separation chamber 3, separation chamber 3 forms with horizontal segment by vertical section that is interconnected, horizontal segment is connected to the bottom of vertical section, top in vertical section is provided with the gas drainage under suction mouth 2 being connected with negative tube, sidepiece is provided with fluid inlet 1, sidepiece at horizontal segment is provided with slag-drip opening, slag-drip opening place is provided with baffle plate 5, baffle plate 5 is hinged on separator box 4, the bottom of baffle plate 5 is connected with flexible check apron 6, baffle plate 5 and flexible check apron 6 block slag-drip opening jointly, flexible check apron 6 adopts flexible material to make.
Wherein, fluid inlet 1 is obliquely installed towards the below of 3 inside, separation chamber, and the extension line of its central axis is crossing with the sidewall of separation chamber's 3 vertical sections.The fluid that can make like this to enter in separation chamber 3 is beaten in vertical section, after convection cell cushions, water and cinder etc. are discharged from slag-drip opening, make in addition the fluid that enters into separation chamber 3 further form eddy current, be convenient to methane gas floating, then discharge from gas drainage under suction mouth 2.
The bottom surface of separation chamber 3 is made up of the inclined-plane of two different gradients, so that the discharge of water and cinder.
Two edges of separator box 4 bottoms can be designed as and upwarp structure, so that the movement of separator box.
In the course of work, the fluid-mixings such as gas, water and cinder are in piping enters into separation chamber 3, the kinetic energy that enters the fluid dependence of separation chamber 3 itself forms eddy current, methane gas floating, and discharge through the negative tube that is connected with gas drainage under suction mouth 2, the thing such as water and cinder after separation is discharged through slag-drip opening.When the fluid expulsion such as water and cinder, flexible check apron 6 can be according to the size of how many automatic adaptation slag-drip openings of Fluid Volume, can prevent that like this gas from overflowing from slag-drip opening, improves gas separating effect.In the time having cinder to pile up in separation chamber 3, can dig baffle plate 5 and carry out labor cleaning.
