Description

Technical Field

[0001] The utility model relates to the field of separation devices, in particular to a coal gas water tar separation device. Background Art

[0002] In coal chemical production, it is often necessary to obtain coal gas through coal gasification and then separate it to provide raw materials for subsequent chemical production. The raw coal gas produced after coal gasification contains a large amount of mixed impurities, such as dust, tar, etc., and must be separated before the next step of production. Usually, high-pressure water spraying is used to wash the raw coal gas, and the obtained coal gas water contains water, dust, and tar.

[0003] Chinese Patent No. CN202221191341.8 discloses a coal gas water primary tar separation device, which includes a cylinder body 1, a large conical cap 11, and a power unit 17. A central pipe 3 is vertically arranged at the center of the cylinder body 1. A coal gas water inlet pipe 2 is arranged on the side wall of the cylinder body 1, and the coal gas water inlet pipe 2 is fixedly connected to the central pipe 3. An overflow tank 4 is arranged at the middle position of the central pipe 3. A coal gas water outlet pipe 5 is arranged on the side wall of the cylinder body 1, and the coal gas water outlet pipe 5 is fixedly connected to the side wall of the overflow tank 4; a partition plate 6 is arranged at the position below the overflow tank 4 of the central pipe 3, and the partition plate 6 is fixedly connected to the central pipe 3. There is a gap between the edge of the partition plate 6 and the cylinder body 1. The space inside the cylinder body 1 above the partition plate 6 is the first sedimentation area, and the space inside the cylinder body 1 below the partition plate 6 is the second sedimentation area; a plurality of downcomer pipes 7 facing the second sedimentation area are arranged at the edge of the partition plate 6; the lower end of the central pipe 3 is fixedly connected with an oil collecting hopper 8, and there is a gap at the connection, through which coal gas water can pass. The oil collecting hopper 8 is conical. A tar outlet pipe 9 is arranged on the side wall of the cylinder body 1, and the tar outlet pipe 9 is fixedly connected to the top of the oil collecting hopper 8.

[0004] As can be seen from the above, the lower independent drive unit is used instead of the upper drive mode, avoiding the transmission main shaft running through the entire tank body, shortening the length of the main shaft, effectively solving the problem of insufficient rigidity of the overhead drive shaft. At the same time, the drive shaft does not need to run through the internal parts of the primary tar separator, effectively simplifying the internal structure. However, this case still has the following deficiencies: in the work of separating coal gas water tar, the prior art usually uses fixed points to spray coal gas. During use, the water flow cannot fully cover the coal gas, resulting in certain limitations in use, and there are some cases where the coal gas cannot be effectively filtered. At the same time, when collecting water, the water flowing out through the channel will be accompanied by a certain amount of coal gas transportation. When the coal gas flows out with the water flow, it will cause energy waste and corresponding safety hazards.

[0005] Therefore, a coal gas water tar separation device is proposed for the above problems. Content of the Utility Model

[0025] During operation, the filter chamber 21 is installed on the intake flange 22, so that gas can enter the interior of the filter chamber 21 through the intake flange 22, and the filtered gas is discharged and collected outward through the exhaust flange 39.

[0026] Furthermore, the filter chamber 21 is fixedly installed at the top of the fixed frame 1, and a connection chamber 35 is fixedly installed at the top of the fixed frame 1;

[0027] During operation, through the installation of the fixed frame 1, it is beneficial to support the whole during the overall operation and ensure the stability of the whole during the operation.

[0028] Furthermore, two sliding plates 32 are fixedly installed in the inner cavity of the filter chamber 21. Four pulleys 31 are respectively movably installed on the two sliding plates 32, and a movable frame 27 is movably installed on one side of the four pulleys 31;

[0029] During operation, the filter chamber 21 fixes the sliding plates 32, and the cooperation between the sliding plates 32 and the pulleys 31 is beneficial to realize the horizontal movement of the movable frame 27 in the inner cavity of the filter chamber 21.

[0030] Furthermore, a chute is opened at the top of the movable frame 27, and the reciprocating roller 26 is movably installed through the chute. Two intake flanges 28 are fixedly installed at the top of the movable frame 27, and a spray pipe 29 is fixedly installed at the bottom of the movable frame 27;

[0031] During operation, water is conveyed through the installation of the water inlet flange 28 and then output outward through the spray pipe 29. When the filtration chamber 21 is operating, the reciprocating roller 26 rotates circumferentially around the output shaft 25. During the movement, the reciprocating roller 26 cooperates with the chute of the movable frame 27, which is conducive to the reciprocating movement of the movable frame 27.

[0032] Furthermore, a delivery pipe 33 is fixedly installed at the bottom of the collection hopper 23. A stepper motor 34 is fixedly installed on one side of the delivery pipe 33, and a screw conveyor 36 is fixedly installed at the output end of the stepper motor 34.

[0033] During operation, power is provided by the stepper motor 34 to drive the screw conveyor 36 to rotate inside the delivery pipe 33, which is conducive to conveying the water collected by the collection hopper 23.

[0034] Furthermore, a connection chamber 35 is fixedly installed on one side of the delivery pipe 33. A separation chamber 37 is fixedly installed at the top of the connection chamber 35.

[0036] Working principle: In the first embodiment, by driving the servo motor 24, the output shaft 25 performs a rotational motion. When the output shaft 25 rotates, it generates a linkage on the movable frame 27 through the reciprocating roller 26. The movable frame 27 slides on the slide plate 32 through the installed pulley 31, and cooperates with the linkage of the reciprocating roller 26 to realize the reciprocating motion of the movable frame 27. The spray pipe 29 installed at the bottom of the movable frame 27 sprays the gas actively. During the movement, the active range of the water flow jet is increased to ensure full contact between the high-pressure water flow and the gas, removing a large amount of mixed impurities contained in the raw gas generated after gasification, such as dust, tar, etc. The mixed impurities fall onto the collection hopper 23 with the water flow due to gravity for collection.

[0037] In the second embodiment, the bottom of the collection hopper 23 is connected to a delivery pipe 33, and the mixed water is conveyed to the inside of the delivery pipe 33 through their connection. The inner wall of the delivery pipe 33 cooperates with the rotation of the screw conveyor 36 to convey the mixed water. When it is conveyed to the position of the connection chamber 35, some gas will be mixed in the mixed water when it falls. The gas contained in the water is separated from the mixed water through the separation chamber 37, and the gas flows back to the inside of the exhaust flange 39 through the separation chamber 37, and the liquid is discharged and collected outward through the drain pipe 38.
