Description

Technical Field

[0001] The present invention relates to the technical field of coalbed methane dewatering and drying equipment, and specifically to a coalbed methane dewatering and drying equipment and method. Background Technique

[0002] Coalbed methane is a gas resource associated with and symbiotic with coal, referring to hydrocarbon gases stored in coal seams, mainly composed of methane, and belonging to unconventional natural gas. Coalbed methane mainly adsorbs on the surface of coal matrix particles, and part of it is free in coal pores or dissolved in coal seam water. It is an associated mineral resource of coal and a newly emerging clean energy and chemical raw material. After preliminary collection, a small amount of water vapor is carried in the gas. If these water vapors cannot be filtered out well, it will have a great impact on the utilization of coalbed methane. Moreover, the water vapor contained in coalbed methane will accelerate the corrosion rate of the inner wall of the gas transmission pipeline, reduce the service life of the gas transmission pipeline, and increase the probability of safety accidents.

[0003] Under the existing technology, the dewatering and drying equipment can basically meet people's usage requirements. Most of the existing dewatering methods adopt the method of condensation dewatering. This method often causes the water vapor in the coalbed methane passing quickly through the dewatering mechanism not to come into contact with the surface of the condensation blades in time, resulting in incomplete dewatering of the coalbed methane.

[0006] Further, the water removal mechanism further includes a rotary bottom plate fixedly connected to one end of the output rotating shaft away from the forward and reverse motor. One end of the rotary bottom plate away from the output rotating shaft is fixedly connected with a condensation blade. One end of the condensation blade away from the rotary bottom plate is rotatably connected to the inner wall of the equipment cylinder. The top inner wall of the equipment cylinder is fixedly connected with an isolation inclined plate. The middle of the isolation inclined plate is fixedly penetrated by an output cylinder.

[0007] Further, a water circulation mechanism is arranged at the bottom of the output cylinder. The water circulation mechanism includes two input water channels opened on one side of the condensation blade close to the output cylinder, and two output water channels are opened inside the condensation blade on the side away from the output cylinder. A plurality of connecting pipes are fixedly connected to the top end of the condensation blade. The connecting pipes communicate the input water channels with the output water channels.

[0008] Further, the water circulation mechanism further includes a drain pipe fixedly connected to one end of the output water channel away from the connecting pipe. A water inlet pipe is fixedly connected to one end of the input water channel away from the connecting pipe. One end of the drain pipe away from the output water channel is fixedly connected with a water pump. A water filter cover is fixedly connected to the bottom of the water pump.

[0009] Further, an auxiliary cleaning mechanism is arranged on the inner wall of the equipment cylinder. The auxiliary cleaning mechanism includes a plurality of sliding grooves opened on the inner wall of the equipment cylinder. A plurality of sliding blocks are slidably connected inside the sliding grooves. A compression spring is fixedly connected to the top of the sliding blocks.

One end of the cleaning rod away from the sliding block is slidably connected to the condensation blade. One end of the output rotating shaft away from the forward and reverse motor is fixedly connected with a diversion cover.

[0010] Further, an anti-blocking mechanism is arranged at the bottom of the equipment cylinder. The anti-blocking mechanism includes a push rod fixedly connected to the bottom of the sliding block. One end of the push rod away from the sliding block is fixedly connected with a push ring.

[0011] Further, the anti-blocking mechanism further includes a limiting groove opened on the inner side of the push ring. A sliding ring is slidably connected to the bottom of the water filter cover. A connecting block is fixedly connected to the side wall of the sliding ring. The connecting block is slidably connected inside the limiting groove.

[0012] A method for a coalbed methane water removal and drying device includes the following steps: Step 1: Condensation water removal; Step 2: Water circulation; Step 3: Clean the condensed water; Step 4: Anti-blocking.

[0013] The present invention has the following beneficial effects: (1). In the present invention, by providing an auxiliary cleaning mechanism, the forward and reverse motor at one end of the connecting plate drives the output rotating shaft to rotate forward and reverse periodically. When the output rotating shaft rotates clockwise, the output rotating shaft drives the condensation blades to rotate clockwise. The clockwise rotation of the condensation blades drives the cleaning rod to slide along the surface of the condensation blades. At this time, the cleaning rod quickly scrapes off the condensed water droplets on the condensation blades. This setting is beneficial to increasing the contact area between the surface of the condensation blades and the coalbed methane, thereby accelerating the condensation of water vapor in the coalbed methane on the surface of the condensation blades and improving the working efficiency of the device. On the other hand, it is beneficial to avoid the phenomenon that the water vapor in the coalbed methane passing quickly through the inside of the spiral chamber fails to contact the surface of the condensation blades in time, resulting in incomplete water removal from the coalbed methane.

[0014] (2). In the present invention, when using this coalbed methane water removal and drying equipment, first, cooling water is added to the bottom of the equipment cylinder through the water replenishing port. At this time, the coalbed methane enters the inside of the equipment cylinder through the air inlet pipe, and the temperature of the coalbed methane rises through the heating ring inside the air inlet pipe. This setting is beneficial to evaporating the liquid water particles in the coalbed methane into water vapor. At this time, the coalbed methane flows along the spiral chamber inside the equipment cylinder under the guiding action of the isolation inclined plate. This setting is beneficial to increasing the flow path of the coalbed methane inside the equipment cylinder and increasing the contact area between the coalbed methane and the surface of the condensation blades, so that the water vapor in the coalbed methane fully contacts the surface of the condensation blades and condenses into water droplets attached to the surface of the condensation blades. The coalbed methane flows through the inside of the output cylinder towards the end close to the top cover and is then discharged through the air outlet pipe. This setting is beneficial to efficiently removing the water in the coalbed methane on the one hand and improving the water removal efficiency of the device on the other hand.

[0015] (3). In the present invention, by providing a water circulation mechanism, when using the device, the water pump is started. The water pump extracts the condensed water at the bottom of the equipment cylinder through the water filter cover and enters the input water trough through the water inlet pipe. At this time, the condensed water enters the output water trough through the connecting pipe at the top of the input water trough and is then discharged into the equipment cylinder through the drain pipe at the bottom of the output water trough to complete the water circulation. This setting is beneficial to the continuous flow of the condensed water inside the condensation blades, so that there is a large temperature difference between the surface temperature of the condensation blades and the high-temperature coalbed methane, which is beneficial to the condensation of water vapor in the coalbed methane on the surface of the condensation blades. At the same time, the water condensed on the surface of the condensation blades flows along the condensation blades into the bottom of the equipment cylinder. This setting is beneficial to saving water resources.

[0016] (4) In the present invention, by providing an anti-blocking mechanism, when the condensation blade rotates, the sliding block at one end of the cleaning rod is driven by the condensation blade to slide upward. The sliding block squeezes the compression spring upward along the sliding groove. At this time, the sliding block drives the push rod at the bottom to move upward. The upward movement of the push rod drives the push ring to move upward. The upward movement of the push ring drives the connecting block inside the limiting groove to move upward. The connecting block drives the sliding ring to move upward along the water filtering cover. This setting is beneficial to preventing impurities in the coalbed methane from entering the bottom of the equipment cylinder through the condensed water at the same time and blocking the water filtering cover, and avoiding impurities from entering the internal water circulation mechanism and causing blockage of the input water channel and the output water channel, thereby ensuring the efficient and stable operation of the device.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The output end of the forward and reverse motor 203 is fixedly connected with an output rotating shaft 204. An isolation cylinder 205 is fixedly connected to the inner bottom wall of the equipment cylinder 1.

[0023] The water removal mechanism 2 further includes a rotating bottom plate 206 fixedly connected to one end of the output rotating shaft 204 away from the forward and reverse motor 203. One end of the rotating bottom plate 206 away from the output rotating shaft 204 is fixedly connected with a condensation blade 207. One end of the condensation blade 207 away from the rotating bottom plate 206 is rotatably connected to the inner wall of the equipment cylinder 1. The top inner wall of the equipment cylinder 1 is fixedly connected with an isolation inclined plate 208. The middle of the isolation inclined plate 208 is fixedly penetrated by an output cylinder 209. A spiral cavity 210 is formed between the inner wall of the equipment cylinder 1 and the outer wall of the output cylinder 209. The function of this component is that when using this coalbed methane water removal and drying equipment, first, cooling water is added to the bottom of the equipment cylinder 1 through the water replenishing port 14. At this time, the coalbed methane enters the interior of the equipment cylinder 1 through the air inlet pipe 12. The temperature of the coalbed methane rises through the heating ring 201 inside the air inlet pipe 12. This setting is beneficial to evaporating the liquid water particles in the coalbed methane into water vapor. At this time, under the guiding action of the isolation inclined plate 208, the coalbed methane flows along the spiral cavity 210 inside the equipment cylinder 1. This setting is beneficial to increasing the flow path of the coalbed methane inside the equipment cylinder 1 and increasing the contact area between the coalbed methane and the surface of the condensation blade 207, so that the water vapor in the coalbed methane fully contacts the surface of the condensation blade 207 and condenses into water droplets attached to the surface of the condensation blade 207. The coalbed methane flows through the interior of the output cylinder 209 towards the end close to the top cover 16 and is then discharged through the air outlet pipe 13. This setting is beneficial on the one hand to efficiently removing the water in the coalbed methane, and on the other hand to improving the water removal efficiency of the device.

[0024] A water circulation mechanism 3 is arranged at the bottom of the output cylinder 209. The water circulation mechanism 3 includes two input through water channels 301 opened on one side of the condensation blade 207 close to the output cylinder 209. Two output through water channels 302 are opened inside the condensation blade 207 on the side away from the output cylinder 209. A plurality of connecting pipes 303 are fixedly connected to the top end of the condensation blade 207. The connecting pipes 303 communicate the input through water channels 301 with the output through water channels 302.

[0025] The water circulation mechanism 3 further includes a drain pipe 305 fixedly connected to one end of the output water trough 302 away from the connecting pipe 303. One end of the input water trough 301 away from the connecting pipe 303 is fixedly connected with a water inlet pipe 304. One end of the drain pipe 305 away from the output water trough 302 is fixedly connected with a water pump 306. The bottom of the water pump 306 is fixedly connected with a water filter cover 307. The function of this component is that by setting the water circulation mechanism 3, when using this device, the water pump 306 is started. The water pump 306 extracts the condensed water at the bottom of the equipment cylinder 1 through the water filter cover 307 and enters the input water trough 301 through the water inlet pipe 304. At this time, the condensed water enters the output water trough 302 through the connecting pipe 303 at the top of the input water trough 301, and then is discharged into the equipment cylinder 1 through the drain pipe 305 at the bottom of the output water trough 302 to complete the water circulation. Such a setting is beneficial for the condensed water to continuously flow inside the condensation blades 207, so that the surface temperature of the condensation blades 207 has a large temperature difference from the high-temperature coalbed methane, which is conducive to the condensation of water vapor in the coalbed methane on the surface of the condensation blades 207. At the same time, the water condensed on the surface of the condensation blades 207 flows along the condensation blades 207 into the bottom of the equipment cylinder 1. Such a setting is beneficial for saving water resources.

[0026] Embodiment 2, the difference from Embodiment 1 is that; as Figures 1 - 9 shown, an auxiliary cleaning mechanism 4 is provided on the inner wall of the equipment cylinder 1. The auxiliary cleaning mechanism 4 includes a plurality of sliding grooves 401 opened on the inner wall of the equipment cylinder 1. A plurality of sliding blocks 402 are slidably connected inside the sliding grooves 401. The top of the sliding blocks 402 is fixedly connected with a compression spring 403. One end side wall of the sliding blocks 402 away from the sliding grooves 401 is fixedly connected with a cleaning rod 404. The cleaning rod 404 is slidably connected to the condensation blade 207 at one end away from the sliding block 402. One end of the output rotating shaft 204 away from the forward and reverse motor 203 is fixedly connected with a diversion cover 405. The function of this component is that by setting the auxiliary cleaning mechanism 4, the forward and reverse motor 203 at one end of the connecting plate 202 drives the output rotating shaft 204 to rotate forward and reverse periodically. When the output rotating shaft 204 rotates clockwise, the output rotating shaft 204 drives the condensation blade 207 to rotate clockwise. The clockwise rotation of the condensation blade 207 drives the cleaning rod 404 to slide along the surface of the condensation blade 207. At this time, the cleaning rod 404 quickly scrapes off the condensed water droplets on the condensation blade 207. Such a setting is beneficial for increasing the contact area between the surface of the condensation blade 207 and the coalbed methane, thereby accelerating the condensation of water vapor in the coalbed methane on the surface of the condensation blade 207 and improving the working efficiency of this device; on the other hand, it is beneficial to avoid the phenomenon that the water vapor in the coalbed methane passing quickly through the spiral cavity 210 fails to contact the surface of the condensation blade 207 in time, resulting in incomplete water removal of the coalbed methane.

[0027] A clogging prevention mechanism 5 is provided at the bottom of the equipment cylinder 1.

A connecting block 505 is fixedly connected to the side wall of the sliding ring 504, and the connecting block 505 is slidably connected inside the limiting groove 503. The function of this component is that by setting the clogging prevention mechanism 5, when the condensation blade 207 rotates, the condensation blade 207 drives the sliding block 402 at one end of the cleaning rod 404 to slide upward. The sliding block 402 squeezes the compression spring 403 upward along the sliding groove 401. At this time, the sliding block 402 drives the push rod 501 at the bottom to move upward. The upward movement of the push rod 501 drives the push ring 502 to move upward. The upward movement of the push ring 502 drives the connecting block 505 inside the limiting groove 503 to move upward. The connecting block 505 drives the sliding ring 504 to move upward along the water filtering cover 307. This setting is beneficial to prevent impurities in the coalbed methane from entering the bottom of the equipment cylinder 1 through the condensed water at the same time and clogging the water filtering cover 307, and avoid impurities entering the internal water circulation mechanism 3 and causing blockage of the input water through groove 301 and the output water through groove 302, so as to ensure the efficient and stable operation of the device.

[0029] A method for a coalbed methane water removal and drying device includes the following steps: Step 1: Condensation water removal; Step 2: Water circulation; Step 3: Cleaning condensed water; Step 4: Anti-clogging.

[0030] A specific application of this embodiment is: When using this coalbed methane dewatering and drying equipment, first add cooling water to the bottom of the equipment cylinder 1 through the water replenishing port 14. At this time, the coalbed methane enters the interior of the equipment cylinder 1 through the air inlet pipe 12. The temperature of the coalbed methane rises through the heating ring 201 inside the air inlet pipe 12. Such a setting is beneficial to evaporating the liquid water particles in the coalbed methane into water vapor. At this time, under the guiding action of the isolation inclined plate 208, the coalbed methane flows along the spiral cavity 210 inside the equipment cylinder 1.

The coalbed methane flows through the interior of the output cylinder 209 towards one end close to the top cover 16 and is then discharged through the air outlet pipe 13. Such a setting is beneficial to efficiently removing the moisture in the coalbed methane on the one hand and improving the water removal efficiency of the device on the other hand; by setting the water circulation mechanism 3, when using the device, start the water pump 306.

When the output rotating shaft 204 rotates clockwise, the output rotating shaft 204 drives the condensation blade 207 to rotate clockwise. The clockwise rotation of the condensation blade 207 drives the cleaning rod 404 to slide along the surface of the condensation blade 207. At this time, the cleaning rod 404 quickly scrapes off the condensed water droplets on the condensation blade 207. Such a setting is beneficial to increasing the contact area between the surface of the condensation blade 207 and the coalbed methane, thereby accelerating the condensation of water vapor in the coalbed methane on the surface of the condensation blade 207 and improving the working efficiency of the device; on the other hand, it is beneficial to avoid the phenomenon that the water vapor in the coalbed methane passing quickly through the inside of the spiral chamber 210 fails to contact the surface of the condensation blade 207 in time, resulting in incomplete water removal of the coalbed methane; by setting up the anti-blocking mechanism 5, when the condensation blade 207 rotates, the condensation blade 207 drives the sliding block 402 at one end of the cleaning rod 404 to slide upward. The sliding block 402 squeezes the compression spring 403 upward along the sliding groove 401. At this time, the sliding block 402 drives the push rod 501 at the bottom to move upward.
