Description

Technical Field

[0001] This utility model relates to the field of hydrogen purification technology, and in particular to a hydrogen quality improvement device. Background Technology

[0002] In hydrogen production systems employing natural gas and steam reforming processes, high-temperature syngas requires efficient cooling to maintain stable equipment operation. However, current cooling systems suffer from insufficient heat transfer efficiency and lag in temperature control response, resulting in inadequate recovery of waste heat from the syngas. This leads to energy waste and can easily trigger equipment overheat protection mechanisms, causing production shutdowns.

[0003] Chinese Patent CN217725089U discloses a hydrogen quality improvement device, including a cooling tank and a washing tank. The cooling tank has a support base at the bottom and a gas equalization pipe inside. A branch pipe connects two gas equalization pipes. An inlet pipe and an outlet pipe are located on opposite sides of the gas equalization pipe. A water spray pipe with nozzles is located at the top of the cooling tank. A refrigeration tank with cooling plates is connected to the bottom of the cooling tank. A first water pump is located on one side of the refrigeration tank. A washing tank contains washing liquid. The device uses the first water pump to spray cooling water through the spray pipes and nozzles to cool the hydrogen in the branch pipes. The refrigeration tank circulates the cooling water. The washing tank and washing liquid purify other gases in the hydrogen. A drive motor, pulley, and transmission belt ensure that the hydrogen is evenly and effectively cooled by the cooling water spray as it passes through the branch pipes, improving the cooling effect and efficiency.

[0004] However, the above technical solution has the following shortcomings: when the device cools the gas equalization pipe, it sprays water onto the gas equalization pipe through a spray pipe and nozzles. This cooling method is prone to some parts not receiving good spray cooling effect during spraying, and the number of nozzles is relatively small, affecting the cooling rate. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a hydrogen quality improvement device that enhances the cooling effect on the conduit for transporting hydrogen, prevents the surface of the conduit from being unable to receive adequate spraying, and improves cooling efficiency.

[0006] The present invention provides a hydrogen quality improvement device, comprising a base and a cooling device. A cooling box is mounted on the base, and a cylindrical body is mounted on the cooling box. A gas guide pipe is rotatably connected inside the cylindrical body. The cooling device includes a first connecting frame and two second connecting frames inside the cylindrical body, multiple nozzles arranged in a linear array on the first and second connecting frames, a support base on the base, a connecting rod and a fixing rod on the first connecting frame, a push ball on the connecting rod, and a drive mechanism on the support base. The connecting rod is rotatably connected to the fixing rod. The drive mechanism includes a first motor on the support base, a main shaft and a fixing block rotatably connected to the support base, a turntable coaxially mounted on the main shaft, an eccentric shaft on the turntable, a rotating rod movably connected to the eccentric shaft, a slider slidably connected to the fixing block, a push rod on the slider, and a retaining frame on the push rod. The first motor and the main shaft are driven together, one end of the push rod is movably connected to the rotating rod, and the push ball is located inside the groove of the retaining frame.

[0007] Preferably, the cylinder is provided with an arc-shaped through hole for the connecting rod to slide.

[0008] Preferably, a first water pump is provided on the base, and a first conduit is provided on the first water pump. One end of the first conduit is connected to the cooling box, and the other end of the first conduit is connected to the first connecting frame.

[0009] Preferably, a second water pump is provided on the base, and a second conduit is provided on the second water pump. One end of the second conduit is connected to the cooling box, and the other end of the second conduit is connected to the second connecting frame.

[0012] Preferably, an exhaust pipe is connected to the air duct, and a washing box, a drying box, and a recycling box are provided on the base, with the exhaust pipe and the washing box connected together.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] Example 1

[0022] like Figures 1-4 As shown, the hydrogen quality improvement device proposed in this embodiment includes a base 1 and a cooling device; a cooling box 2 is provided on the base 1, a cylinder 3 is provided on the cooling box 2, and a gas guide pipe 4 is rotatably connected inside the cylinder 3.

[0023] The cooling device includes a first connecting frame 5 and two second connecting frames 6 disposed inside the cylinder 3, multiple nozzles 7 linearly arrayed on the first connecting frame 5 and the second connecting frame 6, a support seat 11 disposed on the base 1, a connecting rod 8 and a fixing rod 9 disposed on the first connecting frame 5, a push ball 10 disposed on the connecting rod 8, and a drive mechanism disposed on the support seat 11; the connecting rod 8 is rotatably connected to the fixing rod 9.

[0024] The driving mechanism includes a first motor 12 mounted on a support base 11, a main shaft 13 and a fixed block 17 rotatably connected to the support base 11, a turntable 14 coaxially mounted on the main shaft 13, an eccentric shaft 15 mounted on the turntable 14, a rotating rod 16 movably connected to the eccentric shaft 15, a slider 18 slidably connected to the fixed block 17, a push rod 19 mounted on the slider 18, and a retaining frame 20 mounted on the push rod 19; the first motor 12 and the main shaft 13 are driven together, one end of the push rod 19 is movably connected to the rotating rod 16, the push ball 10 is located inside the groove of the retaining frame 20, and the cylinder 3 is provided with an arc-shaped through hole for the connecting rod 8 to slide.

[0025] In this embodiment, multiple nozzles 7 with different orientations on the first connecting frame 5 and the second connecting frame 6 spray the gas guide pipe 4 to reduce the temperature of the hydrogen. Simultaneously, the first motor 12 is activated to drive the main shaft 13 to rotate. The main shaft 13 drives the turntable 14 and the eccentric shaft 15 to rotate. The eccentric shaft 15 pulls one end of the rotating rod 16 to reciprocate, while the other end of the rotating rod 16 drives the push rod 19 to move. Under the guidance of the fixed block 17 on the slider 18, the push rod 19 drives the clamping frame 20 to move horizontally reciprocally. The push ball 10 is located between the clip frames 20. When the clip frames 20 move, the push ball 10 moves. Since the push ball 10 and the connecting rod 8 are integrated and rotate around the axis of the fixed rod 9, the connecting rod 8 drives the first connecting frame 5 to swing back and forth along the arc-shaped through hole. This causes the first connecting frame 5 to drive the nozzle 7 on it to spray while swinging back and forth around the axis of the fixed rod 9, thereby increasing the spray range and ensuring that all parts of the air guide pipe 4 can be sprayed, thus ensuring the cooling effect and having good practicality.

[0026] Example 2

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a hydrogen quality improvement device is proposed. Compared with the first embodiment, in this embodiment, a first water pump 26 is provided on the base 1, and a first conduit 27 is provided on the first water pump 26. One end of the first conduit 27 is connected to the cooling box 2, and the other end of the first conduit 27 is connected to the first connecting frame 5. A second water pump 28 is provided on the base 1, and a second conduit 29 is provided on the second water pump 28. One end of the second conduit 29 is connected to the cooling box 2, and the other end of the second conduit 29 is connected to the second connecting frame 6.

[0028] In this embodiment, the first water pump 26 and the first conduit 27 are used to draw cooling water from the cooling tank 2 and deliver it into the first connecting frame 5. Then, the nozzle 7 on the first connecting frame 5 plays a leading role in cooling the hydrogen in the gas guide pipe 4. The second water pump 28 and the second conduit 29 are used to deliver cooling water into the second connecting frame 6. The nozzle 7 on the second connecting frame 6 plays an auxiliary role in cooling the hydrogen in the gas guide pipe 4.

An air inlet pipe 25 with a rotary joint 24 is connected to the gas guide pipe 4, and the gas guide pipe 4 and the rotary joint 24 are rotatably connected.

[0031] In this embodiment, when the air duct 4 is sprayed, the second motor 21 is started to drive the first gear 22 to rotate. The first gear 22 and the second gear 23 mesh and drive each other. The rotary joint 24, which is provided in conjunction with the air duct 4, rotates the air duct 4 without affecting the normal delivery of the air inlet pipe 25, so that the cooling water is sprayed evenly and effectively on the air duct 4, thereby improving the cooling effect and cooling efficiency.

The exhaust pipe 30 and the washing box 31 are connected.

[0034] In this embodiment, when the gas guide tube 4 is discharged from the cooling box 2, it passes through the washing box 31 and the drying box 32 in sequence to purify and collect other gases in the hydrogen. The recovery box 33 is used to heat, concentrate and reflux the washing liquid that has undergone hydrogen reaction. This part of the process adopts the processing method disclosed in the utility model with patent publication number CN217725089U, so it will not be described in detail.
