There are many related technologies for preparing hydrogen, among which hydrogen is produced by electrolysis of water. Electrolysis of water is to use electrical energy to decompose water to obtain hydrogen. In the process of preparing hydrogen, due to process and other problems, the prepared hydrogen contains more water. In order to make the hydrogen purer, the hydrogen needs to be dried.

When cleaning is needed, pinch the rotating block to rotate the rotating block through the rotating rod. When the rotating block completely falls off the surface of the collecting plate, pinch the handle and pull it backward to make the collecting plate slide backward inside the drying box. When the collecting plate completely slides out of the drying box, it can be cleaned, thereby avoiding the situation that the existing collecting box is fixedly installed inside the drying box, and when the personnel are busy at work and the collecting box is full of water, it cannot be cleaned in time, resulting in excessive water accumulation inside the drying box and difficult cleaning later.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4As shown, a hydrogen production device with a drying structure comprises: a shell 1, a drying cylinder 2 is installed inside the shell 1, and the two ends of the drying cylinder 2 are respectively an air inlet 21 and an exhaust port 22, a condenser 3 is arranged inside the drying cylinder 2, a drip hole 4 is opened at the bottom of the drying cylinder 2, and the exhaust port 22 is connected to the water absorption mechanism 7 through a connecting pipe 6; a water storage tank 5 is installed below the shell 1, wherein a drain port 51 is installed at the bottom end of one side of the water storage tank 5, and the drain port 51 is controlled to be opened and closed by a gate plate 52, and a sensing chamber 53 is arranged on the same side as the drain port 51, and a float 54 is arranged inside the sensing chamber 53, and the sensing chamber 53 is connected to the drain port 51 through a floating chamber 55, and a connecting rod 56 is arranged inside the floating chamber 55, one end of the connecting rod 56 is connected to the gate plate 52, and the other end of the connecting rod 56 is connected to the float 54, and the water storage tank 5 is connected to the sensing chamber 53 through a connecting port 58.
[0023] When the prepared hydrogen is dried and produced, the prepared hydrogen is first introduced into the drying cylinder 2 through the air inlet 21. In the drying cylinder 2, the moisture in the hydrogen will be cooled and condensed by contacting the condenser 3, and the condensed water droplets will drip into the water storage tank 5 through the drip hole 4, so as to achieve the purpose of separating hydrogen from water and realize the drying of hydrogen. As the water droplets continue to drip into the water storage tank 5, the water level in the water storage tank 5 will continue to rise. When it rises to the connecting port 58, the water will flow into the sensing chamber 53 at the same time. Then, as the water level in the sensing chamber 53 increases, the buoyancy of the float 54 will also increase, and the float 54 will be driven to float upward as the water level increases. Through the rise of the float 54 and the connection of the connecting rod 56, the gate plate 52 will be driven to rise. As the gate plate 52 rises, the blockage of the gate plate 52 on the drain port 51 will also be released, and part of the water in the water storage tank 5 will also be discharged from the drain port 51, so as to achieve the purpose of automatic drainage.
[0024] Then, as the water is discharged, the water level in the water tank 5 will also drop, and the buoyancy of the float 54 will also decrease, and then it will fall downward, thereby driving the gate 52 to fall and re-block the drain outlet 51. When the water level reaches a certain height again, the gate 52 will reopen, so that the water level in the water tank 5 is maintained within a certain height range.
[0025] Please refer again Figure 2 As shown, the housing 1 includes a housing seat 11 in the lower part, an outer shell cover 12 is arranged above the housing seat 11, the housing seat 11 and the water storage tank 5 are in a communicating structure, the housing 1 and the water storage tank 5 are in a sealing structure, and the two ends of the drying cylinder 2 are fixedly connected to the two ends of the housing 1 by bolts;
[0026] During installation, first clamp the two ends of the drying cylinder 2 on the shell seat 11, and the drip hole 4 of the drying cylinder 2 faces downward to facilitate the moisture precipitated from the hydrogen to drip into the water storage tank 5, and then cover the outer shell cover 12 and tighten it with bolts to form a sealed space between the shell 1 and the water storage tank 5. When drying the hydrogen, the hydrogen will not only fill the entire drying cylinder 2 and flow in the drying cylinder 2, but also fill the entire shell 1 and the part above the water level line in the water storage tank 5 with the drip hole 4. The formed sealing structure can avoid leakage during the drying process and ensure the safety of the work.
[0027] Please refer again Figure 3 As shown, the spring 57 is sleeved on the connecting rod 56, one end of the spring 57 presses on the gate plate 52, and the other end of the spring 57 presses on the top of the floating chamber 55;
[0028] The main function of the spring 57 is to facilitate the resetting of the gate plate 52, that is, the gate plate 52 can fall and block the drain outlet 51 in time and accurately, so that the gate plate 52 can more flexibly control the opening and closing of the drain outlet 51. The floating cavity 55 is arranged to provide space for the up and down movement of the gate plate 52, and a sealing structure is adopted between the floating cavity 55 and the drain outlet 51, so as to avoid water seepage between the floating cavity 55 and the drain outlet 51 through the floating cavity 55.
[0029] The lowest end of the communication port 58 is flush with the lowest end of the floating chamber 55, and the lowest end of the communication port 58 is higher than the top end of the drainage port 51;
[0030] When the water level reaches the lowest end of the connecting port 58, it will flow into the floating chamber 55 through the connecting port 58. The water level in the floating chamber 55 will rise as the water level in the water tank 5 rises, thereby providing buoyancy for the float 54, facilitating timely driving the gate 52 to open the drain port 51 for drainage. The lowest end of the connecting port 58 is set higher than the top end of the drain port 51 in order to keep the water level line in the water tank 5 above the drain port 51, thereby preventing hydrogen above the water level line in the water tank 5 from leaking from the drain port 51.
[0031] like Figure 4 As shown, at least two groups of water suction mechanisms 7 are provided, and each group of water suction mechanisms 7 includes a water suction box 71, a control valve 72 is provided between each water suction box 71 and the connecting pipe 6, a feeding port 73 is installed at the top of the water suction box 71, a discharge port 74 is provided at the bottom of the water suction box 71, a plug plate 75 is plugged and connected in the discharge port 74, and the control valve 72 is electrically connected to the control mechanism 8 through a wire;
[0032] The water absorption mechanism 7 is provided to dry the hydrogen dried by the drying cylinder 2 again, so as to improve the dryness of the hydrogen. In addition, at least two groups of water absorption mechanisms 7 can be used alternately. When one group of desiccant is replaced, the other group can be used, so that the device can be produced without stopping during the production of dry hydrogen, thereby improving the work efficiency.
[0033] During use, if the desiccant in one group of the water absorption mechanism 7 needs to be replaced, the control mechanism 8 can be used to control the closing of the control valve 72 of this group to cut off the inflow of hydrogen, and open the control valve 72 of the other group to allow the hydrogen to flow to the other group, so as to avoid affecting the dry production of hydrogen when replacing the desiccant. Then, the desiccant is replaced. First, the plug plate 75 of the discharge port 74 is pulled out to discharge the desiccant in the water absorption box 71 from the discharge port 74, and then the plug plate 75 is inserted, and the new desiccant is poured into the water absorption box 71 from the filling port 73, and the end cover is screwed on to seal the filling port 73 to complete the replacement of the desiccant.
[0034] Working principle: when the prepared hydrogen is dried and produced, the prepared hydrogen is first introduced into the drying cylinder 2 through the air inlet 21. In the drying cylinder 2, the moisture in the hydrogen will be cooled and condensed when it contacts the condenser 3, and the condensed water droplets will drip into the water storage tank 5 through the drip hole 4, so as to achieve the purpose of separating hydrogen from water and realize the drying of hydrogen. As the water droplets continue to drip into the water storage tank 5, the water level in the water storage tank 5 will continue to rise. When it rises to the connecting port 58, the water will flow into the sensing chamber 53 at the same time. Then, as the water level in the sensing chamber 53 increases, the buoyancy of the float 54 will also increase, and the float 54 will be driven to float upward as the water level increases. Through the rise of the float 54 and the connection of the connecting rod 56, the gate plate 52 will be driven to rise. As the gate plate 52 rises, the gate plate 52 will release the blockage of the drain port 51, and part of the water in the water storage tank 5 will be discharged from the drain port 51, so as to achieve the purpose of automatic drainage.
