[0002] As a drying device, the main function of a hydrogen dryer is to absorb moisture from hydrogen when it is delivered into the dryer, thereby increasing the purity of the hydrogen for subsequent use. However, existing hydrogen dryers lack an oxygen alarm mechanism. When too much oxygen is delivered into the dryer, they cannot promptly alert staff that excessive oxygen content in the hydrogen may pose a safety hazard, thus affecting the safety of the hydrogen dryer. Utility Model Content

[0003] To achieve the above objectives, the present invention adopts the following technical solution:

[0004] An internally drying hydrogen dryer includes a drying shell and a shielding cover. The shielding cover is bolted to the top of the drying shell. An inlet pipe is connected through one side of the drying shell, and an outlet pipe is connected through the other side of the drying shell. Fixed flanges are fixedly connected to the outer surfaces of both the inlet and outlet pipes. A drying layer is fixedly connected inside the drying shell. A fixed plate is connected through the bottom of the drying shell. Support rods are fixedly connected to the bottom of the fixed plate, and four support rods are provided. Casters are fixedly connected to the bottom of the support rods.

[0005] Preferably, a temperature detector is connected through the front of the drying shell.

[0006] Preferably, an electric heating tube is fixedly connected inside the drying shell, and the electric heating tube is located on the outside of the drying layer.

[0007] Preferably, a pressure relief head is fixedly connected to the top of the shielding cover, and two pressure relief heads are provided. A pressure relief pipe is fixedly connected to the bottom of the pressure relief head, and an electric throttle valve is connected through the outer surface of the pressure relief pipe.

[0008] Preferably, an oxygen detector is connected through the top of the shielding cover, and the oxygen detector is located inside the pressure relief head.

[0009] Preferably, a sound generator is fixedly connected to the top of the shielding cover, and the sound generator is located in front of the oxygen detector.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This invention adds an oxygen detector and a sound generator. The oxygen detector is connected to the top of the cover to detect the oxygen content inside the drying shell. When the oxygen content inside the drying shell is too high, the electromagnetic relay inside the oxygen detector switches, sending electrical energy to the inside of the sound generator. The small lever inside the sound generator vibrates at a high frequency, emitting a sharp sound, thereby alerting nearby personnel that the oxygen content inside the hydrogen is too high and there may be a risk of explosion.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] Reference Figure 1 , Figure 2 and Figure 4An internally drying hydrogen dryer includes a drying shell 1 and a shielding cover 2. The shielding cover 2 is bolted to the top of the drying shell 1. The drying shell 1 provides fixing points for the shielding cover 2, inlet pipe 3, outlet pipe 4, drying layer 6, fixing plate 7, temperature detector 10, and heating element 11, which are fixedly connected to its outer surface and interior. The shielding cover 2 is bolted to the top of the drying shell 1 to provide shielding for the top of the drying shell 1 and ensure the airtightness of the drying shell 1. The shielding cover 2 is bolted to the top of the drying shell 1 and provides fixing points for the pressure relief head 12, oxygen detector 15, and sound generator 16, which are fixedly connected to its outer surface. An inlet pipe 3 is connected through one side of the drying shell 1 and is connected to an external hydrogen input pipe. Next, the inlet pipe 3 delivers hydrogen to the interior of the drying shell 1. An outlet pipe 4 is connected to the other side of the drying shell 1, and is connected to an external hydrogen storage component. As hydrogen is continuously delivered to the interior of the drying shell 1, it enters the outlet pipe 4 under pressure, and then delivers the hydrogen to the external hydrogen storage component. Fixed flanges 5 are fixedly connected to the outer surfaces of both the inlet pipe 3 and the outlet pipe 4. When it is necessary to fix the inlet pipe 3 and the outlet pipe 4, external bolts can be inserted into the hydrogen input pipe and the hydrogen storage component by external force, and then the external bolts can be inserted into the fixed flanges 5 to complete the fixation of the inlet pipe 3 and the outlet pipe 4. An internal drying layer 6 is fixedly connected, and the drying layer 6 uses filter cloth to wrap activated alumina desiccant. Water vapor passing through the drying layer 6 is absorbed under pressure. A fixing plate 7 is connected through the bottom of the drying shell 1, and the fixing plate 7 is fixedly connected to the outer surface of the drying shell 1, providing a fixing point for the support rods 8 fixedly connected to its bottom. Support rods 8 are fixedly connected to the bottom of the fixing plate 7, providing fixing points for the casters 9 fixedly connected to its bottom. Four support rods 8 are provided, and casters 9 are fixedly connected to the bottom of the support rods 8. The casters 9 are fixedly connected to the bottom of the support rods 8, and the supporting force transmitted from the ground to the interior provides support for the entire dryer. When the dryer is pushed by an external force, the casters 9 move along... The dryer rotates in the direction of external force, thereby improving the overall mobility of the dryer. A temperature detector 10 is connected through the front of the drying shell 1. During the drying process of the drying layer 6, the temperature data inside the drying shell 1 is detected to determine the drying status of the drying layer 6. An electric heating tube 11 is fixedly connected inside the drying shell 1. When it is necessary to dry the activated alumina desiccant inside the drying layer 6, electrical energy can be transmitted to the inside of the electric heating tube 11 through an external control component. At this time, the water vapor inside the activated alumina desiccant evaporates under the action of heat, so that the drying layer 6 can be reused. The electric heating tube 11 is located on the outside of the drying layer 6. A pressure relief head 12 is fixedly connected to the top of the shielding cover 2. When steam enters the inside of the pressure relief head 12 under pressure,Under pressure, the pressure relief head 12 guides water vapor to the external environment, completing the water vapor output. Two pressure relief heads 12 are provided. A pressure relief pipe 13 is fixedly connected to the bottom of each pressure relief head 12, providing space for water vapor to enter the interior of the pressure relief head 12. An electric throttle valve 14 is connected through the outer surface of the pressure relief pipe 13. Normally, the electric throttle valve 14 is blocked to ensure the sealing of the drying shell 1. When it is necessary to output water vapor from inside the drying shell 1, electrical energy can be supplied to the electric throttle valve 14 via an external control component. At this time, the electric throttle valve 14 opens, driving the internal connection of the pressure relief pipe 13.

[0019] Reference Figure 1 An oxygen detector 15 is connected through the top of the cover 2 and is located inside the pressure relief head 12. The oxygen detector 15 is connected through the top of the cover 2 to detect the oxygen content inside the drying shell 1. When the oxygen content inside the drying shell 1 is too high, the electromagnetic relay inside the oxygen detector 15 switches and sends electrical energy to the inside of the sounder 16. The sounder 16 is fixedly connected to the top of the cover 2 and is located in front of the oxygen detector 15. When electrical energy is sent to the inside of the sounder 16 through the oxygen detector 15, the small lever inside the sounder 16 vibrates at a high frequency and emits a sharp sound, thereby reminding the surrounding staff that the oxygen content inside the hydrogen is too high and there may be a risk of explosion.

[0020] The functional principle of this utility model can be explained through the following operation: First, when hydrogen needs to be dried, external bolts can be inserted into the hydrogen input pipe and the hydrogen collection component, and the external bolts can be inserted into the fixed flange 5 to complete the fixing of the inlet pipe 3 and the outlet pipe 4. When hydrogen is delivered to the inside of the inlet pipe 3, the inlet pipe 3 delivers the hydrogen to the inside of the drying shell 1. The drying layer 6 is wrapped with filter cloth. Under pressure, the hydrogen passes through the drying layer 6. At this time, the active alumina desiccant inside the drying layer 6 absorbs the water vapor. At the same time, under pressure, the hydrogen enters the inside of the outlet pipe 4. The outlet pipe 4 delivers the hydrogen to the inside of the external hydrogen collection component to complete the output of hydrogen.
