Description

Technical Field

[0001] The present invention relates to the technical field of coalbed methane dehydration and drying equipment, in particular to coalbed methane dehydration and drying equipment and a method. Background Art

[0002] Coalbed methane (CBM) is a gas resource associated with coal. It refers to hydrocarbon gas stored in coal seams, primarily composed of methane, and is considered an unconventional natural gas. CBM, primarily adsorbed on the surface of coal particles, with some remaining free within coal pores or dissolved in coalbed water, is a mineral resource associated with coal and a newly emerging clean energy source and chemical feedstock. After initial collection, CBM carries a small amount of water vapor. If this water vapor is not effectively filtered out, it can significantly impact its utilization. Furthermore, the water vapor contained in CBM can accelerate the corrosion of gas pipeline walls, reducing their service life and increasing the likelihood of accidents.

Most of the dehydration methods under the existing technology adopt the condensation dehydration method, which often causes the water vapor in the coalbed methane that quickly passes through the dehydration mechanism to fail to contact the surface of the condensation blade in time, thereby causing incomplete dehydration of the coalbed methane.

[0009] Furthermore, a water circulation mechanism is provided at the bottom of the output cylinder, which includes two input water grooves opened inside the condensing blade on the side close to the output cylinder, and two output water grooves opened inside the condensing blade on the side away from the output cylinder. Several connecting pipes are fixedly connected to the top of the condensing blade, and the connecting pipes connect the input water grooves with the output water grooves.

[0010] Furthermore, the water circulation mechanism also includes a drain pipe fixedly connected to the end of the output water trough away from the connecting pipe, the end of the input water trough away from the connecting pipe is fixedly connected to the water inlet pipe, the end of the drain pipe away from the output water trough is fixedly connected to the water pump, and the bottom of the water pump is fixedly connected to a water filter cover.

[0011] Furthermore, an auxiliary cleaning mechanism is provided on the inner wall of the equipment cylinder, and 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, the top of the sliding block is fixedly connected to an extrusion spring, and a cleaning rod is fixedly connected to the side wall of the sliding block away from the sliding groove, and the end of the cleaning rod away from the sliding block is slidably connected to the condensing blade, and the end of the output shaft away from the forward and reverse motor is fixedly connected to the air guide cover.

[0012] Furthermore, an anti-blocking mechanism is provided at the bottom of the equipment cylinder, and the anti-blocking mechanism includes a push rod fixedly connected to the bottom of the sliding block, and an end of the push rod away from the sliding block is fixedly connected to a push ring.

[0013] Furthermore, the anti-blocking mechanism also includes a limiting groove opened on the inner side of the push ring, the bottom of the water filter cover is slidably connected to the sliding ring, the side wall of the sliding ring is fixedly connected to a connecting block, and the connecting block is slidably connected to the inside of the limiting groove.

[0014] A method for dewatering and drying coalbed methane equipment includes the following steps:

[0015] Step 1: Condensation and water removal;

[0016] Step 2: Water circulation;

[0017] Step 3: Clean the condensed water;

[0018] Step 4: Anti-blocking.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention sets an auxiliary cleaning mechanism. The forward and reverse motor at one end of the connecting plate drives the output shaft to rotate forward and reverse periodically. When the output shaft rotates clockwise, the output shaft drives the condensing blades to rotate clockwise. The clockwise rotation of the condensing blades drives the cleaning rod to slide along the surface of the condensing blades. At this time, the cleaning rod quickly scrapes off the condensed water droplets on the condensing blades. This setting is conducive to increasing the contact area between the condensing blade surface and the coalbed methane, thereby accelerating the condensation of water vapor in the coalbed methane on the surface of the condensing blades and improving the working efficiency of the device; on the other hand, it is conducive to avoiding the phenomenon that the water vapor in the coalbed methane that quickly passes through the spiral cavity fails to contact the condensing blade surface in time, thereby causing incomplete water removal from the coalbed methane.

[0021] (2) According to the present invention, when the coalbed methane dehydration and drying equipment is used, cooling water is first added to the bottom of the equipment tube through the water supply port. At this time, the coalbed methane enters the interior of the equipment tube through the air inlet pipe, and the temperature of the coalbed methane is increased by the heating ring inside the air inlet pipe. This arrangement is conducive to evaporating the liquid water particles in the coalbed methane into water vapor. At this time, the coalbed methane flows along the spiral cavity inside the equipment tube under the guidance of the isolation inclined plate. This arrangement is conducive to increasing the flow distance of the coalbed methane in the equipment tube and increasing the contact area between the coalbed methane and the surface of the condensing blade, so that the water vapor in the coalbed methane is fully in contact with the surface of the condensing blade and condensed into water droplets attached to the surface of the condensing blade. The coalbed methane flows through the inside of the output tube to the end close to the top cover and is then discharged through the air outlet pipe. On the one hand, this arrangement is conducive to efficiently removing moisture from the coalbed methane and on the other hand, it is conducive to improving the dehydration efficiency of the device.

[0022] (3) The present invention sets a water circulation mechanism. When the device is used, the water pump is started. The water pump draws the condensed water from the bottom of the equipment barrel 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 then is discharged into the equipment barrel through the drainage pipe at the bottom of the output water trough to complete the water circulation. This arrangement is conducive to the condensed water continuing to flow inside the condensing blades, so that the surface temperature of the condensing blades maintains a large temperature difference with the high-temperature coalbed methane, which is conducive to the condensation of water vapor in the coalbed methane on the surface of the condensing blades. At the same time, the water condensed on the surface of the condensing blades flows along the condensing blades to the bottom of the equipment barrel. This arrangement is conducive to saving water resources.

[0023] (4) The present invention sets an anti-blocking mechanism. When the condensing blade rotates, the condensing blade drives the sliding block at one end of the cleaning rod to slide upward, and the sliding block squeezes the extrusion spring upward along the sliding groove. At this time, the sliding block drives the push rod at the bottom to move upward, and the push rod moves upward to drive the push ring to move upward, and the push ring moves upward to drive the connecting block inside the limit groove to move upward, and the connecting block drives the sliding ring to move upward along the water filter cover. This arrangement is conducive to preventing impurities in the coalbed methane from clogging the water filter cover when entering the bottom of the equipment barrel through the condensed water, and avoiding impurities from entering the water circulation mechanism and causing the input water trough and the output water trough to be blocked, thereby ensuring the efficient and stable operation of the device.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The water pump 306 extracts condensed water from the bottom of the equipment cylinder 1 through the water filter cover 307 and enters the interior of 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 is then discharged into the equipment tube 1 through the drain pipe 305 at the bottom of the output water trough 302 to complete the water circulation. This arrangement is conducive to the condensed water continuing to flow inside the condensing blade 207, so that the surface temperature of the condensing blade 207 maintains a large temperature difference with the high-temperature coalbed methane, which is conducive to the condensation of water vapor in the coalbed methane on the surface of the condensing blade 207. At the same time, the water condensed on the surface of the condensing blade 207 flows along the condensing blade 207 to the bottom of the equipment tube 1.
