Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen purification equipment, and in particular to a separation device for hydrogen production. Background Technology

[0002] Hydrogen, with its advantages of being clean, pollution-free, efficient, storable, and transportable, is considered an ideal secondary energy source and is widely used in fuel cell vehicles, the electronics industry, and the chemical industry. As a secondary energy source, hydrogen needs to be produced from other energy sources. Common hydrogen production methods include coal gasification, natural gas reforming, biomass fermentation, and water electrolysis. To obtain relatively pure hydrogen, except for water electrolysis, all hydrogen production processes require hydrogen separation to remove impurities from the hydrogen-rich gas. Therefore, hydrogen separation devices are needed. Existing hydrogen separation devices filter the mixed gas through a filter screen. However, the filtered dust particles accumulate on the filter screen over time, causing blockage and hindering gas flow, thus affecting the subsequent normal separation of hydrogen and resulting in low separation efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a separation device for hydrogen production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A separation device for hydrogen production includes a workbench and support frames. Support frames are fixed to the left and right ends of the upper surface of the workbench. A separation cylinder is fixed between the two support frames. A stirring motor is fixed to the right side of the separation cylinder. Stirring blades are fixed to the outer wall of the drive shaft at the output end of the stirring motor. An inlet pipe is embedded in the lower interior of the separation cylinder. A base plate is fixed to the bottom of the separation cylinder. A collection box is fixed to the upper middle part of the separation cylinder. A servo motor is fixed to the right rear end of the collection box. A lead screw is rotatably connected to the left side of the drive shaft at the output end of the servo motor. A scraper is embedded in the upper middle part of the collection box. A filter screen is fixed in the upper middle part of the collection box. Collection boxes are embedded on both the left and right sides of the collection box. An exhaust pipe is embedded in the top of the collection box.

[0006] Preferably, the base plate covers the exhaust end of the intake pipe, and the interior of the base plate has exhaust holes evenly spaced from left to right.

[0007] Preferably, the stirring blade is positioned directly above the base plate, and the separation cylinder is filled with a quantity of purified water.

[0008] Preferably, the upper left and right ends of the inside of the collection box are provided with discharge troughs, and the two collection boxes are located just below the outer side of the discharge troughs.

[0009] Preferably, the front and rear ends of the upper part of the collection box are provided with sliding grooves, the scraper is longitudinally embedded in the two sliding grooves, and the outer wall of the lead screw is connected to the rear end of the inner wall of the scraper by threads.

[0010] Preferably, the top of the scraper is in close contact with the bottom of the filter screen, the vertical cross-sectional area of ​​the scraper is the same as the vertical cross-sectional area of ​​the discharge trough, and both discharge troughs and scrapers are on the same horizontal plane.

[0011] 1. After hydrogen enters the collection box, it passes through the filter screen and rises. The filter screen can filter out dust particles and other impurities in the hydrogen. Then, the servo motor drives the lead screw to rotate clockwise and counterclockwise in the scraper, causing the scraper to slide left and right on the lower surface of the filter screen. This scrapes away the dust particles filtered out from the lower surface of the filter screen. When the dust particles are pushed to the left and right sides of the filter screen by the scraper, they will fall into the collection box through the discharge ports at the left and right ends of the collection box. This prevents the filtered dust particles from accumulating at the bottom of the filter screen for a long time and affecting the subsequent normal filtration of hydrogen. The hydrogen flow is smoother and the filtration and separation efficiency is higher.

[0012] 2. After hydrogen enters the separator cylinder through the inlet pipe, it will generate bubbles in the pure water at the bottom of the inner cylinder and rise to the surface. Then, it will pass through the exhaust hole in the bottom plate and be dispersed into several smaller bubbles by the bottom plate. At the same time, the stirring motor will drive the stirring blades to rotate and stir the pure water and hydrogen, so that the hydrogen and pure water can fully contact and mix. This allows the dust particles in the hydrogen to be retained in the pure water, resulting in high filtration and separation efficiency and greater ease of use. Attached Figure Description

[0018] Workbench 1, support frame 101, separation cylinder 102, stirring motor 103, stirring blade 104, air inlet pipe 105, bottom plate 106, collection box 2, servo motor 201, lead screw 202, scraper 203, filter screen 204, collection box 205, exhaust pipe 206. Detailed Implementation

[0019] Example 1, referring to Figure 1-4 A separation device for hydrogen production includes a workbench 1 and a support frame 101. The support frame 101 is fixed to both the left and right ends of the upper surface of the workbench 1. A separation cylinder 102 is fixed between the two support frames 101. A stirring motor 103 is fixed to the right side of the separation cylinder 102. A stirring blade 104 is fixed to the outer wall of the drive shaft at the output end of the stirring motor 103. An air inlet pipe 105 is embedded in the lower part of the separation cylinder 102. A bottom plate 106 is fixed to the bottom of the separation cylinder 102. A collection box 2 is fixed to the upper middle part of the separation cylinder 102. A servo motor 201 is fixed to the right rear end of the collection box 2. A lead screw 202 is rotatably connected to the left side of the drive shaft at the output end of the servo motor 201. A scraper 203 is embedded in the upper middle part of the collection box 2. A filter screen 204 is fixed in the upper middle part of the collection box 2. Collection boxes 205 are embedded on both the left and right sides of the collection box 2. An exhaust pipe 206 is embedded in the top of the collection box 2.

[0020] The base plate 106 covers the exhaust end of the intake pipe 105, and the interior of the base plate 106 has exhaust holes that are equidistantly spaced from left to right.

[0021] After hydrogen enters the interior of the separator 102 through the inlet pipe, the hydrogen will generate bubbles in the pure water at the bottom of the inner cylinder 102 and rise up. Then, it passes through the exhaust hole in the bottom plate 106 and is dispersed into several smaller bubbles by the bottom plate 106, so that the hydrogen and pure water can fully contact and mix.

[0022] The stirring blade 104 is positioned directly above the base plate 106, and the separation cylinder 102 is filled with a certain amount of pure water.

[0023] When hydrogen rises in pure water, the stirring motor 103 drives the stirring blade 104 to rotate, stirring the pure water and hydrogen. This ensures that the hydrogen and pure water come into full contact and mix, leaving the dust particles in the hydrogen in the pure water. This results in higher filtration and separation efficiency and greater ease of use.

[0024] Example 2 differs from Example 1 in that, in this example, the upper left and right ends of the collection box 2 are both provided with discharge troughs, and the two collection boxes 205 are both located on the lower outer side of the discharge troughs.

[0025] The front and rear ends of the upper part of the collection box 2 are provided with sliding grooves. The scraper 203 is longitudinally embedded in the two sliding grooves. The outer wall of the screw 202 is connected to the rear end of the inner wall of the scraper 203 by threads.

[0026] The top of the scraper 203 is in close contact with the bottom of the filter screen 204. The vertical cross-sectional area of ​​the scraper 203 is the same as the vertical cross-sectional area of ​​the discharge chute. Both discharge chute and scraper 203 are on the same horizontal plane.

[0027] After hydrogen enters the collection box 2, it passes through the filter screen 204 and then rises. At this time, the filter screen 204 can filter out the dust particles and other impurities contained in the hydrogen. Then, the servo motor 201 drives the lead screw 202 to rotate clockwise and counterclockwise in the scraper 203, so that the scraper 203 slides left and right on the lower surface of the filter screen 204 to scrape the dust particles filtered out from the lower surface of the filter screen 204.

[0028] When dust particles are pushed to the far left and far right of the filter screen 204 by the scraper 203, they will fall into the collection box 205 through the discharge ports at the left and right ends of the collection box 2. This prevents the filtered dust particles from accumulating at the bottom of the filter screen 204 for a long time and affecting the subsequent normal filtration of hydrogen. The hydrogen flow is smoother and the filtration and separation efficiency is higher.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
