[0002] When measuring and detecting gas concentration on site, in certain specific occasions, such as underground coal mine borehole gas extraction pipelines with abundant groundwater, there will be high gas humidity, water droplets in the gas, or even water and gas coexisting. At this time, if the gas is directly extracted and sent into the instrument for gas concentration analysis and measurement, it is very easy to draw water vapor or liquid water into the sensor inside the instrument, resulting in large measurement errors or sensor damage. Therefore, a method for steam-water separation and water blocking is proposed. Summary of the invention

[0003] Technical issues solved

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide a method for steam-water separation and water blocking and a method of using the method, which can effectively achieve the effect of steam-water separation and prevent water from entering the instrument.

[0005] Technical Solution

[0006] To achieve the above object, the present invention provides the following technical solution: a method for steam-water separation and water blocking, characterized in that it comprises the following steps:

[0007] 1) A vacuum device is installed at the water blocking outlet. The gas-water mixture enters the air inlet channel from the device inlet and first passes through the inverted vortex structure for preliminary gas-liquid separation.

[0008] 2) The separated gas continues to rise along the rotating acceleration separation structure under the action of extraction, and further gas-liquid separation is carried out in the rotating acceleration separation structure.

[0009] 3) The gas separated by the rotating acceleration separation structure is discharged from the water blocking structure.

[0010] Preferably, the vortex structure in step one includes a vortex channel, a vortex inlet located below the vortex channel, a vortex outlet located above the vortex channel, and a first vortex block and a second vortex block located inside the vortex channel, the vortex inlet is connected to an end of the air inlet channel away from the device inlet, the vortex outlet is connected to the water storage space through the water inlet, and the edges of the first vortex block and the second vortex block are arranged in an arc shape, wherein the soda-water mixture in step one enters the vortex channel from the vortex inlet, and the soda-water mixture forms a diversion and vortex effect inside the vortex channel to perform preliminary gas-liquid separation.

[0011] Preferably, the rotational acceleration separation structure in step 2 includes an intermediate body with a cross-shaped structure, and spiral ribs spirally fixed on the outer surface of the intermediate body, a spiral channel is formed between the spiral ribs, and the bottom inlet of the spiral channel is connected to the vortex outlet, wherein the separated gas continues to rise along the spiral channel under the action of extraction, and the separated water falls under the action of gravity, blocking the vortex inlet of the vortex structure; due to the action of the extraction force, part of the accumulated water falls from the water inlet into the water storage space under the action of suction, and part of the water is still deposited at the bottom of the vortex structure, and the gas-water mixture can be "washed" by the water deposited at the bottom of the vortex structure under the action of the outlet suction.

[0012] Preferably, after the initial separation by the vortex structure in step two, the gas at the vortex outlet continues to rise along the spiral channel to the top opening under the action of extraction, and the water separated by the spiral channel flows out along the natural water inlet of the spiral channel under its own gravity.

[0013] Preferably, the water-blocking structure in the step includes a water-blocking inlet and a water-blocking outlet, a floating ball movable limiting space is provided between the water-blocking inlet and the water-blocking outlet, a floating ball is provided inside the floating ball movable limiting space, and the water-blocking structure also includes a rubber sealing pad fixed at the water-blocking outlet, and the top opening of the spiral channel is connected to the water-blocking inlet, wherein when there is no water in the floating ball movable limiting space, the floating ball automatically falls off under its own gravity to open the water-blocking outlet, at this time, after further separation by the rotating accelerated separation structure, the gas in the spiral channel can flow freely between the water-blocking inlet and the water-blocking outlet under the action of extraction, and when water gradually fills the floating ball movable limiting space, the floating ball continuously floats up until it contacts the rubber sealing pad and then automatically closes the water-blocking outlet, at this time, water can be prevented from flowing out of the outlet, thereby achieving the purpose of water blocking.

[0014] Beneficial effects:

[0015] Compared with the prior art, the method for steam-water separation and water blocking and its use method have the following advantages:

[0016] Beneficial effects:

[0017] 1. The present invention can form a diversion and vortex effect through the first-stage vortex structure. The vortex part fluid and the diversion part fluid continuously collide and merge, thereby accelerating the flow rate of the lighter gas and slowing down the flow rate of the heavier liquid, thereby preliminarily realizing the gas-liquid separation effect. Combined with the second-stage rotation acceleration separation structure (the cross-star intermediate can increase the path length of the spiral channel rotation acceleration, so that the airflow rotates closer to the edge area, which is more conducive to the separation of water vapor), the gas-water separation effect of the device can be good.

[0018] 2. The vortex structure of the first stage is inverted, that is, the vortex inlet is at the bottom and the vortex outlet is at the top. After the water-vapor mixture is separated at this stage, the water falls under the action of gravity and blocks the vortex inlet; but due to the suction force at the outlet, part of the accumulated water will fall from the water inlet into the water storage space under the action of suction, while part of the water will still be deposited at the bottom of the vortex structure. The steam-water mixture can still be "washed" by the water deposited at the bottom of the vortex structure under the action of the suction force at the outlet, thereby achieving a better dehydration effect in the steam-water mixture.

[0019] 3. The water-blocking structure of the present invention adopts a hydraulic control method, and a floating ball movable limiting space is set between the water-blocking inlet and the water-blocking outlet. When water gradually fills the floating ball movable limiting space, the floating ball continuously floats until it contacts the rubber sealing pad and automatically closes the outlet, thereby preventing water from flowing out of the outlet and achieving the purpose of water blocking; when there is no water in the floating ball movable limiting space, the floating ball automatically falls off under its own gravity, opening the outlet channel, and the gas can flow freely between the inlet and the outlet, finally achieving the function of automatic water blocking by the hydraulic floating ball.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 to Figure 5 As shown, the present invention provides a technical solution: a method for steam-water separation and water blocking, which is based on a device for steam-water separation and water blocking, wherein the device for steam-water separation and water blocking comprises a device shell 1, in which a device inlet 2 is arranged, the device inlet 2 is connected to an air intake channel 3, and the air intake channel 3 is connected to a vortex structure 4, and one end of the vortex structure 4 away from the air intake channel 3 is connected to a rotation acceleration separation structure 5 and a water storage space 6, the output end of the rotation acceleration separation structure 5 is connected to a water blocking structure 7, and the bottom of the water storage space 6 is connected to a drain outlet 8.

[0030] Please pay attention to Figure 2 The vortex structure 4 includes a vortex channel 401, a vortex inlet 402 located below the vortex channel 401, a vortex outlet 403 located above the vortex channel 401, and a first vortex block 404 and a second vortex block 405 located inside the vortex channel 401. The vortex inlet 402 is connected to the end of the air inlet channel 3 away from the device inlet 2, and the vortex outlet 403 is connected to the water storage space 6 through the water inlet 601. The edges of the first vortex block 404 and the second vortex block 405 are set to be arc-shaped. The first-stage vortex Structure 4 is inverted, that is, the vortex inlet 402 is at the bottom and the vortex outlet 403 is at the top. After the water vapor mixture is separated at this level, the water falls under the action of gravity and blocks the vortex inlet 402; but due to the suction force at the outlet, part of the accumulated water will fall from the water inlet into the water storage space 6 under the action of suction, while part of the water will still be deposited at the bottom of the vortex structure 4. The steam-water mixture can still be "washed" by the water deposited at the bottom of the vortex structure under the action of the outlet suction, thereby achieving a better dehydration effect in the steam-water mixture.

[0031] Please pay attention to Figure 3 and Figure 4 The rotational acceleration separation structure 5 includes an intermediate body 501 of a cross-shaped structure, and spiral ribs 502 spirally fixed on the outer surface of the intermediate body 501, a spiral channel 503 is formed between the spiral ribs 502, and the bottom inlet 5031 of the spiral channel 503 is connected to the vortex outlet 403. The first-stage vortex structure 4 can form a diversion and vortex effect, and the vortex part fluid and the diversion part fluid continuously collide and merge, so that the flow rate of the lighter gas is accelerated and the flow rate of the heavier liquid is decelerated, thereby preliminarily realizing the gas-liquid separation effect. Combined with the second-stage rotational acceleration separation structure 5 (the cross-star intermediate body 501 can increase the path length of the rotational acceleration of the spiral channel 503, so that the airflow rotates closer to the edge area, which is more conducive to the separation of water vapor), the gas-water separation effect of the device can be good.

[0032] Please pay attention to Figure 5 The water-blocking structure 7 includes a water-blocking inlet 701 and a water-blocking outlet 702, a floating ball movable limiting space 703 is arranged between the water-blocking inlet 701 and the water-blocking outlet 702, a floating ball movable limiting space 703 is arranged inside the floating ball movable limiting space 703, and the water-blocking structure 7 also includes a rubber sealing pad 705 fixed at the water-blocking outlet 702, and the top opening 5032 of the spiral channel 503 is communicated with the water-blocking inlet 701. The water-blocking structure 7 adopts a hydraulic control method, and a floating ball movable limiting space 703 is arranged between the water-blocking inlet 701 and the water-blocking outlet 702. When water gradually fills the floating ball movable limiting space 703, the floating ball 704 continuously floats until it contacts the rubber sealing pad 705 and automatically closes the outlet, thereby preventing water from flowing out of the outlet, thereby achieving the purpose of water blocking; when there is no water in the floating ball 704 movable limiting space, the floating ball automatically falls off under its own gravity, opening the outlet channel, and the gas can flow freely between the inlet and the outlet, and finally achieving the function of automatic water blocking by the hydraulic floating ball.

[0033] Working principle of a method for steam-water separation and water blocking:

[0034] 1) An air extraction device is installed at the water blocking outlet 702. The gas-water mixture enters the air inlet channel 3 from the device inlet 2, and enters the vortex channel 401 through the vortex inlet 402. The gas-water mixture forms a shunt and vortex effect inside the vortex channel 401, and performs preliminary gas-liquid separation. The separated gas continues to rise along the spiral channel 503 under the action of extraction, and the separated water falls under the action of gravity, blocking the vortex inlet 402 of the vortex structure 4. Due to the action of the extraction force, part of the accumulated water falls into the water storage space 6 from the water inlet 601 under the action of suction, and part of the water is still deposited at the bottom of the vortex structure 4. The gas-water mixture can be "washed" by the water deposited at the bottom of the vortex structure 4 under the action of the outlet suction;

[0035] 2) After the initial separation by the vortex structure 4, the gas at the vortex outlet 403 continues to rise along the spiral channel 503 to the top opening 5032 under the action of extraction, and the water separated by the spiral channel 503 flows out along the natural water inlet 601 of the spiral channel 503 under its own gravity;

[0036] 3) When there is no water in the floating ball movable limiting space 703, the floating ball 704 automatically falls off under its own gravity, because the suction force of the air extraction device is less than the own gravity of the floating ball, and the water blocking outlet 702 is opened. At this time, after further separation by the rotating acceleration separation structure 5, the gas in the spiral channel 503 can flow freely between the water blocking inlet 701 and the water blocking outlet 702 under the action of extraction. When water gradually fills the floating ball movable limiting space 703, the floating ball 704 continuously floats until it contacts the rubber sealing pad 705 and then automatically closes the water blocking outlet 702. At this time, water can be prevented from flowing out of the outlet, thereby achieving the purpose of water blocking.
