Description

Technical Field

[0001] The utility model relates to the technical field of three-phase separators, and more specifically, to an anti-clogging three-phase natural gas separator. Background Art

[0002] The three-phase separator is one of the most commonly used equipment in the process of oil field development and production. The crude oil extracted from the ground is a mixture of oil, gas and water. Since the crude oil entering the crude oil processing station from the oil well contains natural gas, water and sludge, it is necessary to separate the several components of the crude oil through a three-phase separator and enter their respective processing containers for subsequent operations.

[0003] After searching, the patent with publication number CN202893098U discloses a natural gas three-phase separator. This device improves the original separator in which the liquid separated is an oil-water mixture. The lower part of this three-phase separator completely separates water and light oil. There is no water in the oil released from the oil tank of the separator, and there is no oil in the water released from the water tank. The separation effect is good.

[0004] However, the above equipment has the following defects: the collected oil, gas and water mixture will be mixed with some mud blocks, and because the water is discharged after sedimentation, these mud blocks will accumulate in the water supply pipe. If the mud blocks are not broken up and decomposed, the larger mud blocks will block the water supply pipe, making it impossible to carry out normal water supply work. Utility Model Content

[0005] In order to overcome the above defects of the prior art, an anti-clogging natural gas three-phase separator is provided to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A three-phase natural gas separator with anti-blocking function, comprising a separation box, wherein an anti-blocking mechanism is fixedly arranged at the bottom of the separation box:

[0008] The anti-blocking mechanism includes a water supply pipe fixed to the bottom of the separation box, two servo motors are fixedly arranged on the outer wall of the water supply pipe, a rotating shaft is fixedly arranged at the output ends of the two servo motors, a plurality of cutters are fixedly arranged on the two rotating shafts, a double-rod baffle is fixedly arranged on the inner wall of the water supply pipe, a multi-rod baffle is fixedly arranged on the inner wall of the water supply pipe between the two rotating shafts, a mounting plate is clamped at the bottom of the water supply pipe, and a filter plate is fixedly arranged in the mounting plate;

[0009] Through the above technical scheme, the servo motor can drive the cutter on the rotating shaft to break the mud blocks to prevent the mud blocks from clogging the water supply pipe. Since the flow rate in the water supply pipe is too fast, a double-rod baffle is set in the water supply pipe. When the larger mud blocks hit the double-rod baffle, they will be decelerated to facilitate the cutter on the rotating shaft above the water supply pipe to break the mud blocks. After breaking, the smaller mud blocks will reach the cutter on the rotating shaft below the water supply pipe. At this time, the multi-rod baffle can reduce the flow rate of the smaller mud blocks to facilitate the cutter to break the smaller mud blocks to prevent the mud blocks from clogging the water supply pipe. In the case of blockage in the water supply pipe, the separated water is then sent out through the filter plate, and the fine mud powder will remain on the filter plate. The filter plate is installed in the mounting plate, and the mounting plate and the water supply pipe can be connected by bolts. The filter plate can be easily removed through this arrangement. Through such a design, the mud blocks can be broken up in the water supply pipe to prevent blockage problems, and the mud powder can be separated through the filter plate to obtain water with less impurities. In addition, the filter plate is also very convenient to remove and replace, and the internal mud powder can be cleaned regularly to ensure smooth flow and no blockage in the water supply pipe.

[0010] Furthermore, a guide plate is fixedly provided on the inner wall of the separation box, and a plurality of wave-breaking plates are fixedly provided on the top of the guide plate;

[0011] Through the above technical solution, the wave-breaking plate can prevent the water in the separation box from generating waves, and the provision of the guide plate can better enable the water to reach the electric valve.

[0012] Furthermore, an electric valve is provided at the bottom of the separation box, and a first flange is fixedly provided at the bottom of the water supply pipe;

[0013] Through the above technical solution, the electric valve opens the electric valve to send the precipitated water out through the water delivery pipe.

[0014] Furthermore, a mist catching net is fixedly provided on the top of the separation box, an air supply pipe is fixedly provided on the top of the separation box, and a second flange is fixedly provided on the outer wall of the air supply pipe;

[0015] Through the above technical solution, the natural gas will pass through the mist capture net to separate the gas and send it out through the gas delivery pipe, and a second flange is set to facilitate the connection of the external pipeline.

[0016] Furthermore, a water baffle is fixedly provided inside the separation box, an oil delivery pipe is fixedly provided at the bottom of the separation box, and a third flange is fixedly provided on the outer wall of the oil delivery pipe;

[0017] Through the above technical solution, the oil will float on the water after settling for a while. Continuing to inject the oil-gas-water mixture can make the oil pass over the water baffle and send the separated oil out through the oil delivery pipe.

[0018] Furthermore, a feed pipe is fixedly provided on one side of the separation box, and a fourth flange is fixedly provided on the outer wall of the feed pipe;

[0019] Through the above technical solution, the oil-gas-water mixture is sent into the separation box through the feed pipe.

[0020] Furthermore, four pillars are fixedly provided at the bottom of the separation box, and support plates are fixedly provided at the bottom of the four pillars;

[0021] Through the above technical solution, pillars are provided to support the device, and support plates are provided to increase the contact area between the pillars and the ground, so that the device can be placed more stably.

[0022] Technical effects and advantages of the utility model:

[0023] 1. The utility model proposes a natural gas three-phase separator that prevents clogging. Since water is discharged after sedimentation, the collected oil-gas-water mixture will be mixed with some mud blocks, which often clog the water delivery pipe. Therefore, a servo motor is fixedly arranged on the water delivery pipe, and the servo motor can drive the cutter on the rotating shaft to break the mud blocks to prevent the mud blocks from clogging the water delivery pipe. Since the flow rate in the water delivery pipe is too fast, a double-rod baffle is arranged in the water delivery pipe. When the larger mud blocks hit the double-rod baffle, they will be decelerated, so that the cutter on the rotating shaft above the water delivery pipe can break the mud blocks. After breaking, the smaller mud blocks will reach the cutter on the rotating shaft below the water delivery pipe. At this time, the multi-rod baffle can reduce the flow rate of smaller mud blocks, so that the cutter can break up smaller mud blocks to prevent the problem of mud blocks clogging in the water supply pipe. The separated water is then sent out through the filter plate, and the fine mud powder will stay on the filter plate. The filter plate is installed in the mounting plate, and the mounting plate and the water supply pipe can be connected by bolts. The filter plate can be easily removed through this setting. Through such a design, mud blocks can be broken up in the water supply pipe to prevent clogging problems, and mud powder can be separated through the filter plate to obtain water with less impurities. In addition, the removal and replacement of the filter plate is also very convenient, and the internal mud powder can be cleaned regularly to ensure smooth flow and no clogging in the water supply pipe.

[0024] 2. The utility model proposes an anti-clogging natural gas three-phase separator, which delivers the oil-gas-water mixture into the separation box through the feed pipe, and then the natural gas will pass through the mist capture net to separate the gas and send it out through the air delivery pipe, and then the oil-gas-water mixture will settle in the separation box, and after settling for a while, the oil will float above the water, and the oil-gas-water mixture will continue to be injected, so that the oil can pass over the water baffle and the separated oil can be sent out through the oil delivery pipe, and then the electric valve can be opened to send the precipitated water out through the water delivery pipe to complete the separation work, reduce the need for manual operation, and improve efficiency.

[0035] Working principle of the utility model: When the utility model is in use, it is only necessary to feed the oil-gas-water mixture into the separation box 1 through the feed pipe 20, and then the natural gas will pass through the mist capture net 14 to separate the gas and send it out through the air delivery pipe 15, and then the oil-gas-water mixture will settle in the separation box 1, and after settling for a while, the oil will float above the water, and the oil-gas-water mixture will continue to be injected, so that the oil can pass over the water baffle 17 and the separated oil can be sent out through the oil delivery pipe 18, and then the electric valve 12 can be opened to send the precipitated water through the water delivery pipe 2. Since the water is discharged after precipitation, the collected oil-gas-water mixture will be mixed with some mud blocks, and these mud blocks will often be blocked in the water delivery pipe 2, so a servo motor 3 is fixedly set on the water delivery pipe 2, and the servo motor 3 can drive the cutter 5 on the rotating shaft 4 to break the mud blocks to prevent the mud blocks from clogging the water delivery pipe 2.

After crushing, the smaller mud block will reach the cutter 5 on the rotating shaft 4 below the water supply pipe 2. At this time, the multi-rod baffle 7 can reduce the flow rate of the smaller mud block, so that the cutter 5 can crush the smaller mud block to prevent the mud block from clogging in the water supply pipe 2. Then the separated water is sent out through the filter plate 9, and the fine mud powder will stay on the filter plate 9. The filter plate 9 is installed in the mounting plate 8, and the mounting plate 8 and the water supply pipe 2 can be connected by bolts. Through this arrangement, the filter plate 9 can be easily disassembled, so that the filter plate 9 can be cleaned or replaced to clean the mud on the filter plate 9 to ensure smooth flow and no blockage in the water supply pipe 2.
