Description

Technical Field

[0001] This utility model relates to the field of coal-to-hydrogen technology, specifically to a syngas purification device for a coal-to-hydrogen plant. Background Technology

[0002] In coal-to-hydrogen production, the feed gas contains approximately 17% carbon dioxide. Currently, this carbon dioxide is typically removed using a decarbonization tower, also known as an absorption tower. The feed gas enters from the bottom and exits from the top. MDEA, acting as the absorbent, enters from the top of the decarbonization tower and is then sprayed downwards, mixing with the feed gas to absorb both carbon dioxide and hydrogen sulfide.

[0003] A search revealed a Chinese patent publication number: CN221681026U, which discloses a syngas purification device for a coal-to-hydrogen plant. The device includes a purification cylinder with a conical lower end and an open top, a cylinder cover, a support leg at the bottom side of the purification cylinder, a drain pipe at the bottom of the purification cylinder, an L-shaped air inlet pipe with a closed top, an air outlet pipe, an L-shaped water inlet pipe, a spray plate, a clean spray cylinder, an atomizing nozzle, a water guide pipe, a control valve and a first pump body on the water inlet pipe, and an L-shaped exhaust pipe located at the lower end of the spray plate on the upper side of the purification cylinder.

[0004] Although the above-mentioned patent can improve the purification effect of raw material gas, the above-mentioned device still has the following problems: During the use of the device, since the device discharges the liquid after the reaction inside the device directly through the pump body, the liquid after the reaction contains impurities. Directly discharging the liquid through the pump body can easily cause damage to the pump body due to the impurities, thereby reducing the service life of the device to a certain extent. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, through the cooperation of a conical filter plate and a filter frame, can block and filter impurities in the reaction liquid inside the equipment body, thereby reducing the possibility of particulate matter in the reaction liquid entering the pump body and shortening the service life of the device.

A filter box 2 is fixedly connected to the bottom of the main body 1. A pump body and a drain pipe are installed at the bottom of the filter box 2. The pump body and the drain pipe can discharge the reaction liquid in the main body 1. The filter box 2 can block and filter impurities in the reaction liquid in the main body 1. Two symmetrical mounting plates 5 are fixedly connected inside the filter box 2. Mounting grooves 6 are opened on the adjacent sides of the two mounting plates 5. A filter frame 7 is slidably connected inside the mounting groove 6. The filter frame 7 has mesh holes. A conical filter plate 8 is fixedly connected inside the filter frame 7. Through the cooperation of the conical filter plate 8 and the filter frame 7, impurities in the reaction liquid inside the main body 1 can be blocked and filtered, which can reduce the possibility of particulate matter in the reaction liquid entering the pump body and reducing the service life of the device. A support rod 14 is fixedly connected inside the main body 1, and the position of the support rod 14 will not affect the normal operation of the device.

[0021] The conical filter plate 8 is rotatably connected to a rotating shaft 9 extending to the outside of the conical filter plate 8. A cleaning plate 11 is fixedly connected to the outer surface of the rotating shaft 9. The cleaning plate 11 is inclined and arranged on the rotating shaft 9. A brush is provided on the side of the cleaning plate 11 near the conical filter plate 8. The cleaning plate 11 can clean the impurities attached to the surface of the conical filter plate 8 through the brush, and to a certain extent reduce the adhesion of impurities to the conical filter plate 8, so that the reaction liquid passes through the conical filter plate 8 at a slower speed, thereby enabling the device to filter the liquid more smoothly.

[0022] A maintenance groove 4 communicating with the interior of the filter box 2 is provided on one side. A maintenance plate 3 is slidably connected inside the maintenance groove 4. The maintenance plate 3 is fixedly installed on the filter box 2 by bolts. The maintenance plate 3 can position and block the filter frame 7. At the same time, the installation of the maintenance plate 3 by bolts makes the installation and disassembly of the filter frame 7 more convenient, and to a certain extent makes the later maintenance of the filter frame 7 more convenient.

[0023] A fixed frame 12 is fixedly connected to the outer surface of the equipment body 1. A motor 13 is fixedly connected to one side of the fixed frame 12. The motor 13 is an existing structure and will not be described in detail here. The output end of the motor 13 is fixedly connected to a drive shaft 15 through a coupling. One end of the drive shaft 15 rotates through the interior of the equipment body 1 and extends into the interior of the support rod 14. A power transmission rod 18 extending to the outside of the support rod 14 is rotatably connected inside the support rod 14. A transmission frame 19 is fixedly connected to the outer surface of the power transmission rod 18. A transmission rod 10 is fixedly connected to the outer surface of the rotating shaft 9. The power transmission rod 18 drives the transmission frame 19 to rotate. The transmission frame 19 can drive the rotating shaft 9 to rotate through the transmission rod 10, while ensuring that the transmission frame 19 does not affect the installation and removal of the filter frame 7.

[0025] The motor 13 is started by the staff, which drives the transmission shaft 15 to rotate. The transmission shaft 15 drives the power transmission rod 18 to rotate through the first bevel gear 16 and the second bevel gear 17.

[0026] Working principle: This syngas purification device for coal-to-hydrogen plants purifies the coal-to-hydrogen gas through the main body 1. The bottom of the filter box 2 is equipped with a pump and a drain pipe, which discharge the reaction liquid in the main body 1. Through the cooperation of the conical filter plate 8 and the filter frame 7, impurities in the reaction liquid inside the main body 1 can be blocked and filtered, which reduces the possibility of particulate matter in the reaction liquid entering the pump and reducing the service life of the device.

[0027] When the operator starts the motor 13, the motor 13 drives the transmission shaft 15 to rotate. The transmission shaft 15 drives the power transmission rod 18 to rotate through the first bevel gear 16 and the second bevel gear 17. The power transmission rod 18 drives the transmission frame 19 to rotate. The transmission frame 19 drives the rotating shaft 9 to rotate through the transmission rod 10. The rotating shaft 9 drives the cleaning plate 11 to rotate. The cleaning plate 11 can clean the impurities attached to the surface of the conical filter plate 8 through the brush, and to a certain extent reduce the impurities attached to the conical filter plate 8, so that the reaction liquid slows down when passing through the conical filter plate 8, thus enabling the device to filter the liquid more smoothly.
