Description

Technical Field

[0001] This utility model belongs to the field of blowout prevention holes in coal mine drilling, and specifically relates to a gas-water separator for four holes in ordinary drilling. Background Technology

[0002] When drilling in areas with high levels of gas, the complex conditions inside the borehole can cause uneven gas flow, making blowouts very likely. It is necessary to constantly adjust the negative pressure at the borehole opening. During the process of controlling the negative pressure, water and coal slag can easily be drawn into the main system, causing system fluctuations.

[0003] The four-hole gas-water separator is a key piece of equipment in high-gas and coal and gas outburst mines. When using traditional gas-water separators, water and coal slag inside the holes can easily enter the main pipeline directly, and opening a small negative pressure can easily cause gas fluctuations, posing potential risks to production efficiency and safety. Utility Model Content

[0004] In order to solve at least one of the above-mentioned technical problems in the prior art, this utility model provides a four-hole gas-water separator for ordinary drilling.

[0005] This utility model is achieved using the following technical solution: a four-hole gas-water separator for general drilling, comprising an upper cylinder, a lower cylinder, and a pipeline connecting the two; the upper surface of the upper cylinder has a port for connecting the main pipeline negative pressure, the orifice blowout prevention device, the orifice backup negative pressure, and the orifice wall backup negative pressure; the lower cylinder is located at the lower end of the upper cylinder and a second valve is provided on one side of its bottom, and a first valve is provided on the pipeline between the upper cylinder and the lower cylinder.

[0006] Preferably, the diameter of the pipe openings on the upper surface of the upper cylinder is 4 inches; the diameter of the pipe opening connecting the negative pressure of the main pipeline at the upper cylinder is smaller than the diameter of the main pipeline; the main pipeline uses DN350 pipe.

[0007] Preferably, a 2-inch valve is provided on the upper part of one side of the lower cylinder, and this valve is located on the same side as the second valve. Both the first valve and the second valve are 4-inch valves.

[0008] Preferably, the pipeline connecting the upper and lower cylinders is located on the side opposite to the second valve, and the first valve is positioned close to the upper cylinder.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] In this device, the upper layer of the four-hole gas-water separator is directly connected to a main pipeline with negative pressure. Due to the change in pipe diameter, the negative pressure has a certain buffering effect, making it less likely for water to be sucked into the main pipeline, thus preventing coal dust and gas from being drawn into the main pipeline. When the four-hole gas-water separator discharges water, it enters the lower pipeline while maintaining normal negative pressure, reducing the occurrence of accidents. The four-hole gas-water separator adds two four-inch ports to connect to the main pipeline extraction system for gas extraction from the upper extraction pipe of the four-way valve, the gap between the four-way valve and the drill rod, and the gap between the four-way valve and the borehole wall, improving extraction capacity and preventing gas outbursts.

[0011] This device is highly reliable and can effectively solve the problem of water and coal slag entering the extraction system during drilling operations, thus avoiding gas fluctuations caused by water release. Attached Figure Description

[0017] It should be noted that the structures, proportions, sizes, etc., shown in the accompanying drawings of this specification are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the conditions under which this utility model can be implemented. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and purposes that this utility model can produce, should fall within the scope of the technical content disclosed in this utility model.

[0018] This utility model provides an embodiment:

[0019] like Figure 1 , Figure 2 As shown, a four-hole gas-water separator for general drilling includes an upper cylinder 1, a lower cylinder 2, and a pipeline connecting the two. The upper surface of the upper cylinder 1 has a port for connecting the main pipeline negative pressure, the orifice blowout prevention device, the orifice backup negative pressure, and the orifice wall backup negative pressure. The lower cylinder 2 is located at the lower end of the upper cylinder 1, and a second valve 3 is provided on the bottom of one side of it. A first valve 4 is provided on the pipeline between the upper cylinder 1 and the lower cylinder 2.

[0020] In this embodiment, the four-hole gas-water separator adopts a two-layer design. The No. 1 through-hole connects to a main pipeline negative pressure. Due to the change in pipe diameter, the negative pressure has a certain buffering effect, making it less likely for water to be sucked into the main pipeline and preventing coal dust from being drawn into it. The remaining three are air inlets. Air inlet No. 4 connects to the orifice blowout preventer (airbag, water tank), air inlet No. 3 connects to the 4-inch backup negative pressure at the orifice, and air inlet No. 2 connects to the 4-inch backup negative pressure on the orifice wall.

[0021] In this embodiment, the diameter of the pipe openings on the upper surface of the upper cylinder 1 is 4 inches; the diameter of the pipe opening connecting the negative pressure of the main pipeline at the upper cylinder 1 is smaller than the diameter of the main pipeline; the main pipeline uses DN350 pipe.

[0022] A 2-inch valve is also installed on the upper part of one side of the lower cylinder 2, and this valve is located on the same side as the second valve 3. Both the first valve 4 and the second valve 3 are 4-inch valves. The pipeline connecting the upper cylinder 1 and the lower cylinder 2 is located on the opposite side of the second valve 3, and the first valve 4 is located close to the upper cylinder 1.

[0023] Working principle: The upper buffer layer prevents water and coal slag from being sucked into the main pipeline. The lower layer is used to drain water accumulated in the negative pressure pipe. When draining water, the first valve 4 is closed and the second valve 3 is opened to successfully complete the drainage work and ensure the continuous and stable operation of the equipment.

[0024] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
