It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0026] According to one aspect of the present invention, Figure 1-6 As shown, a hydrogen recovery device for a reduction iron smelting rotary kiln that is easy to clean is provided, comprising a filter box 1, a delivery pipe 2 is fixedly connected to the upper right side of the filter box 1, a high-temperature dust removal box 3 is fixedly connected to the right end of the delivery pipe 2, an L-shaped pipe 4 is fixedly connected to the upper right side of the high-temperature dust removal box 3, a heat exchange box 5 is provided on the right side of the high-temperature dust removal box 3, a connecting column 6 is fixedly connected to the outer walls of the filter box 1, the high-temperature dust removal box 3 and the heat exchange box 5, an end of the L-shaped pipe 4 away from the high-temperature dust removal box 3 extends to the interior of the heat exchange box 5, an outlet pipe 7 is fixedly connected to the upper surface of the heat exchange box 5, and an air inlet pipe 8 is fixedly connected to the lower left side of the filter box 1;

[0027] The hydrogen containing impurities is transported to the interior of the filter box 1 through the provided air inlet pipe 8, and large particles and impurities in the hydrogen are filtered through the interior of the filter box 1. The hydrogen after preliminary filtration is then transported to the interior of the high-temperature dust removal box 3 through the provided delivery pipe 2. The high temperature environment inside the high-temperature dust removal box 3 promotes the combustion or decomposition of fine particles in the hydrogen, thereby further purifying the hydrogen. Finally, the hydrogen is transported to the interior of the heat exchange box 5 through the provided L-shaped pipe 4, and heat exchange is performed with the gas after high-temperature dust removal through the cooling medium (such as water, air or other fluid) provided inside the heat exchange box 5, thereby reducing the temperature of the hydrogen and recovering heat energy. Finally, the cooled hydrogen is discharged to the gas separation device through the provided air outlet pipe 7 to obtain pure hydrogen, which can achieve the dual goals of resource recycling and environmental protection while removing moisture and dust from the hydrogen exhaust gas.

[0028] A conical storage box 28 is fixedly connected to the lower surface of the filter box 1, and a discharge port 29 is integrally formed on the lower surface of the filter box 1;

[0029] The conical storage box 28 is provided to facilitate the collection and storage of dust, particulate matter or other impurities falling from the filter box 1. At the same time, the conical design inside the conical storage box 28 helps to ensure that the waste in the conical storage box 28 can be discharged smoothly, avoiding the formation of dead corners or blockages during the storage process. Finally, the waste can be automatically discharged by opening the electromagnetic valve on the outside of the discharge port 29, which can improve the convenience and safety of the equipment.

[0030] The front surface of the filter box 1 is symmetrically rotatably connected to a sealing door 44 via a hinge;

[0031] The hinge is connected to the front surface of the filter box 1 and can be easily opened and closed, making it easy to clean, maintain or replace the filter medium inside the filter box 1, thereby improving the convenience of the device.

[0032] The upper surface of the filter bag skeleton 10 is symmetrically provided with mounting circular holes 21, and an annular groove 22 is integrally formed inside the two mounting circular holes 21. The front and rear surfaces of the inner surfaces of the two mounting circular holes 21 are provided with plug-in vertical grooves 23, and multiple plug-in vertical grooves 23 are respectively connected to the two annular grooves 22. A snap-fit ​​circular plate 24 is provided inside the two mounting circular holes 21. A transmission rod 25 is fixedly connected to the center of the upper surface of the two snap-fit ​​circular plates 24. The tops of the two snap-fit ​​circular plates 24 extend to the top of the mounting ring 9 and are fixedly connected to a control handle 26. The left and right sides of the outer walls of the two snap-fit ​​circular plates 24 are fixedly connected with protrusions 27. Multiple protrusions 27 extend away from the side of the two snap-fit ​​circular plates 24 to the inside of the two annular grooves 22 respectively.

[0033] When the dust bag 11 needs to be disassembled and cleaned, it is only necessary to rotate the control handle 26 to rotate the two protrusions 27 on the outside of the engaging circular plate 24 to the inside of the two plug-in vertical grooves 23. Then, by pulling the filter bag frame 10 downward, the protrusions 27 can be disengaged from the annular grooves 22, and the dust bag 11 can be easily removed. The dust bag 11 can be installed by the reverse operation, thereby improving the convenience of installing the dust bag 11 and ensuring the stable connection and sealing performance between the dust bag 11 and the filter bag frame 10.

[0034] A mounting ring 9 is fixedly connected to the interior of the filter box 1, a filter bag frame 10 is provided below the mounting ring 9, a dust bag 11 is fixedly connected to the lower surface of the filter bag frame 10, a control box 12 is fixedly connected to the center of the upper surface of the filter box 1, a control motor 13 is fixedly connected to the upper surface of the control box 12, a rotating rod 14 is fixedly connected to the bottom end of the output shaft of the control motor 13, the bottom end of the rotating rod 14 extends to the interior of the filter box 1 and is fixedly connected to a connecting plate 15, a movable plate 16 is symmetrically provided on the lower surface of the connecting plate 15, and a plurality of vibrating balls 17 are provided on the opposite sides of the two movable plates 16;

[0035] While the large particles and impurities in the hydrogen are filtered through the provided dust bag 11, the provided control motor 13 can be used to drive the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the two movable plates 16 below and the multiple vibration balls 17 on the outside to rotate together. When the multiple vibration balls 17 are stretched by the centripetal force, they will vibrate and transmit this vibration to the inside of the dust bag 11. When the dust bag 11 is under the action of vibration, it will accelerate the shedding of impurities attached to its surface, thereby improving the hydrogen filtration efficiency and extending the service life of the dust bag 11, reducing the workload of manual maintenance.

[0036] The lower surface of the connecting plate 15 is symmetrically provided with limit slots 18.

The two ends of the two return springs 20 are respectively fixedly connected to the opposite sides of the two movable plates 16 and the inner opposite sides of the two limit slots 18.

[0037] When the connecting plate 15 is driven to rotate by controlling the motor 13, the centripetal force generated by the rotation of the connecting plate 15 simultaneously controls the two movable plates 16 to slide back to back along the two limit grooves 18. At the same time, the two limit rods 19 are set to ensure that the two movable plates 16 slide in a straight line in the two limit grooves 18, so that the multiple vibration balls 17 on the outside are driven by the two connecting plates 15 to better contact with the dust bag 11, and at the same time, the impurities attached to the outside of the dust bag 11 are better vibrated and removed, thereby improving the hydrogen filtration efficiency and extending the service life of the dust bag 11.

[0038] A liquid medicine barrel 30 is fixedly connected to the inner lower surface of the heat exchange box 5, and a liquid inlet pipe 31 is fixedly connected to the right side of the heat exchange box 5. The left end of the liquid inlet pipe 31 extends to the top of the liquid medicine barrel 30, and a spray head 32 is fixedly connected to the lower surface of the liquid inlet pipe 31 and located above the liquid medicine barrel 30. The end of the L-shaped tube 4 away from the high-temperature dust removal box 3 extends to the inside of the liquid medicine barrel 30. A control box 2 33 is fixedly connected to the center of the lower surface of the heat exchange box 5. A control motor 2 34 is fixedly connected to the inner lower surface of the control box 2 33. The top end of the output shaft of the control motor 2 34 extends to the inside of the liquid medicine barrel 30 and is fixedly connected to a stirring paddle 35. A drain port 36 is integrally formed on the lower surface of the heat exchange box 5, which is located on the right side of the control box 2 33.

[0039] After the hydrogen is heated and dusted inside the high-temperature dust removal box 3, it is transported to the inside of the medicine liquid barrel 30 through the provided L-shaped tube 4. At the same time, the medicine liquid is added to the inside of the medicine liquid barrel 30 through the provided liquid inlet pipe 31 and the spray head 32. The hydrogen is transported to the inside of the medicine liquid barrel 30 through the L-shaped tube 4. After sufficient contact with the medicine liquid, most of the gaseous impurities can be removed. At the same time, by operating the provided control motor 2 34 and driving the stirring paddle 35 to rotate, the medicine liquid can be stirred and mixed to ensure the uniformity and reaction efficiency of the medicine liquid. The used medicine liquid can be discharged to the outside through the provided drain port 36.

[0040] A cooling box 37 is fixedly connected to the interior of the heat exchange box 5 and located above the spray head 32. A condensation bucket 38 is fixedly connected to the interior of the cooling box 37. A through-type flow hole 39 is provided on the inner upper surface and the inner lower surface of the condensation bucket 38. A heat exchange chamber 40 is integrally formed inside the cooling box 37 and located outside the condensation bucket 38. A water inlet pipe 41 is integrally formed on the right side of the heat exchange box 5. A drain pipe 42 is integrally formed on the right side of the heat exchange box 5 and located below the water inlet pipe 41. The left ends of the water inlet pipe 41 and the drain pipe 42 extend into the interior of the heat exchange chamber 40. A zeolite molecular sieve 43 is detachably connected to the upper surface of the cooling box 37 and located above the upper flow hole 39.

[0041] When the hydrogen with impurities removed flows to the interior of the condensation bucket 38 through the provided flow hole 39, the cooling medium is transported to the interior of the heat exchange chamber 40 through the provided water inlet pipe 41, and the hydrogen inside the condensation bucket 38 can be subjected to heat exchange treatment. The temperature of the hydrogen exhaust gas is reduced to below the dew point through heat exchange, so that the water vapor in the exhaust gas is condensed into liquid water and discharged. This can not only remove moisture from the exhaust gas, but also reduce the temperature of the exhaust gas, providing suitable conditions for subsequent hydrogen recovery. Finally, the cooling medium is discharged from the heat exchange chamber 40 through the provided drain pipe 42 and recycled or treated, thereby improving the environmental protection of the device. The treated hydrogen is dried by the provided zeolite molecular sieve 43 and then discharged to the gas separation device through the outlet pipe 7.
