DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] The first implementation method:

[0021] Figure 1-4 The present invention shows a hydrogen production equipment with a hydrogen purification structure, comprising a workbench 1 and an electrolyzer 2 fixedly connected thereto, a gas box 3 fixedly connected to the upper end of the workbench 1, a gas box 3 fixedly connected to the end of the gas box 3 close to the electrolyzer 2 fixedly connected to a gas pipe 4, an end of the gas pipe 4 away from the gas box 3 passes through the electrolyzer 2 from the outside to the inside and is sleeved on the graphite electrode in the electrolyzer 2, a plug-in slot 5 is provided on the upper end of the gas box 3, a plug-in plate 6 with a circular hole is movably inserted into the plug-in slot 5, a sponge plate 8 is movably inserted into the plug-in plate 6, an upper rectangular plate 7 and a lower rectangular plate 19 are fixedly connected to the upper and lower ends of the sponge plate 8 respectively, a weighing sensor 9 is fixedly connected to the inner bottom wall of the plug-in plate 6, a warning light 11 is fixedly connected to the upper end of the gas box 3, a controller 12 is fixedly connected to the inner top wall of the gas box 3, and a connecting pipe 13 with a sealing cover is fixedly connected to the upper end of the gas box 3;

[0022] In the initial state, the lower end of the plug-in board 6 is tightly fitted with the inner bottom wall of the gas box 3, the end of the gas pipe 4 away from the electrolytic cell 2 passes through the gas box 3 from the outside to the inside and there is a gap with the sponge plate 8, a sealing cover 15 is placed on the upper end of the electrolytic cell 2, and the upper end of the sealing cover 15 is fixedly connected to the feeding pipe and the gas pipe with a sealing cover, the upper end of the weighing sensor 9 is in contact with the lower end of the lower rectangular plate 19, the side end of the sponge plate 8 is in contact with the inner side wall of the plug-in board 6, and there is a gap between the lower end of the lower rectangular plate 19 and the inner bottom wall of the plug-in board 6.

[0023] The use of this device is divided into the following steps:

[0024] Step 1: The electrolytic cell 2 is provided with a cathode and an anode. When in use, the electrolysis device is placed in the electrolytic cell 2, ensuring that the electrodes do not touch and the electrolyte level is higher than the electrodes. The power supply is connected so that the cathode and anode are connected to the negative and positive poles of the power supply respectively. An electric field is applied, and the hydrogen ions in the water are attracted to the cathode, which receives electrons to generate hydrogen; the oxygen ions are attracted to the anode, which releases electrons to generate oxygen. A gas collection device can then be connected to the gas pipe to collect the generated oxygen, and the generated hydrogen will enter the gas box 3 through the gas pipe 4;

[0025] Step 2: After hydrogen enters the gas box 3, there is a gap between the inner wall of the gas box 3 and the sponge plate 8 (combined with Figure 3 As shown), the hydrogen will diffuse into the space enclosed by the sponge board 8 and the inner wall of the gas box 3. At the same time, a device for collecting hydrogen needs to be connected to the connecting pipe 13 to prevent a large amount of hydrogen from entering the gas box 3, which will increase its internal pressure significantly. After that, the hydrogen with water will pass through the sponge board 8 and the plug-in board 6, and the sponge board 8 will be used to absorb the water in the hydrogen to improve its purity. Subsequently, the filtered hydrogen will enter the device for collecting hydrogen through the connecting pipe 13 to complete the preparation of hydrogen, thereby separating the hydrogen from the water inside and reducing the water content in the hydrogen.

[0026] Step 3: As the sponge board 8 continuously absorbs water, its weight gradually increases, continuously increasing the pressure on the weighing sensor 9. When the pressure detected by the weighing sensor 9 exceeds the set value, the controller 12 will activate the warning light 11 to light up, informing the personnel that the sponge board 8 is saturated with water and needs to be replaced.

[0027] In summary, when the equipment is in use, it can process the saturated water content of hydrogen, reduce the moisture content in hydrogen, and improve its purity.

[0028] The second implementation method:

[0029] This embodiment adds the following structure based on the first embodiment, and the rest of the structure remains the same as the first embodiment, as follows:

[0030] Figure 2 It is shown that the upper end of the upper rectangular plate 7 is fixedly connected to a pull-out plate 14, and a pull-out groove 10 is provided on the inner top wall of the plug-in plate 6, which is movably inserted into the pull-out plate 14. The upper end of the plug-in plate 6 is fixedly connected to a sealing plate 16 with a pair of handles. The outer end of the sealing plate 16 is tightly fitted with the inner wall of the plug-in slot 5. The outer end of the sealing plate 16 is coated with a magnetic coating 17, and the inner wall of the plug-in slot 5 is coated with a magnetic coating 2 18.

[0031] When replacing the sponge plate 8, move the plug-in plate 6 upward and draw it out from the gas box 3, then pull the upper rectangular plate 7, sponge plate 8, lower rectangular plate 19 and pull-out plate 14 toward the outside of the plug-in plate 6 until the four are separated from the plug-in plate 6, and finally replace the sponge plate 8. The pull-out plate 14 can be used to limit the upper rectangular plate 7 to improve the stability of the upper rectangular plate 7 and sponge plate 8 in the plug-in plate 6. After replacing the new sponge plate 8 and inserting the plug-in plate 6 into the gas box 3, the sealing plate 16 will enter the plug-in slot 5 and fit tightly with the inner wall of the plug-in slot 5. At the same time, the magnetic coating 17 will be adsorbed together with the magnetic coating 2 18 to improve the stability of the sealing plate 16 in the plug-in slot 5. The sealing plate 16 can be used to improve the sealing of the plug-in slot 5, so that hydrogen is not easy to escape from the plug-in slot 5.

[0032] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
