Description

Technical Field

[0001] The invention relates to the field of garbage disposal, and in particular to a hydrogen production device for organic domestic garbage. Background Art

[0002] In the pyrolysis process of urban domestic waste, since the water content in urban domestic waste is relatively high, after the waste is put into the pyrolysis furnace, the water will be evaporated first in a high temperature environment. Only after the evaporation of the water is completed will the domestic waste be quickly heated. The evaporation of water takes a certain amount of time. During this period, some volatile substances will evaporate and mix with the hydrogen produced by pyrolysis, resulting in a poor effect of hydrogen production from domestic waste.

[0003] The existing equipment divides the entire pyrolysis furnace into two sections, the upper section of the pyrolysis furnace is the drying section of the pyrolysis furnace, and the lower section of the pyrolysis furnace is the pyrolysis section. Due to the high water content of domestic waste, the domestic waste will clump after crushing. When adding domestic waste to the pyrolysis furnace, the drying section dries the crushed domestic waste, but because the domestic waste will clump, the hot air in the drying section is difficult to fully dry the inside of the domestic waste, making the domestic waste not fully dried. Moreover, when the agglomerated domestic waste is pyrolyzed, it is also pyrolyzed from the outside to the inside. After the pyrolysis of the domestic waste on the outside, a large amount of residue will be left, which affects the pyrolysis of the domestic waste inside, making the pyrolysis of the domestic waste insufficient, and thus making the hydrogen production effect of the domestic waste not good enough. Summary of the invention

DETAILED DESCRIPTION

[0029] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0030] Embodiment 1: A hydrogen production device of organic household waste, such as Figure 1-Figure 4 As shown, it includes a pyrolysis furnace 1, an electric sealing door 2, an outer shell 3, a feed pipe 4, a screw feeder 5, an air outlet pipe 6, an exhaust fan 7, a scattering mechanism and a stirring mechanism. The electric sealing door 2 is welded on the top of the pyrolysis furnace 1, and the outer shell 3 is welded on the electric sealing door 2. Two feed pipes 4 are welded on the outer shell 3, and the two feed pipes 4 are respectively connected with the screw feeder 5 by bolts. The pyrolysis furnace 1 is provided with an air outlet hole, and the air outlet pipe 6 is welded on the air outlet hole of the pyrolysis furnace 1. The air outlet pipe 6 is welded to the feed pipe 4, and the outer shell 3 is connected with the exhaust fan 7 by bolts. The outer shell 3 is provided with a scattering mechanism, and the scattering mechanism is used to scatter domestic waste. The air outlet pipe 6 is provided with a stirring mechanism, and the stirring mechanism is used to stir the domestic waste.

[0031] The feed pipe 4, the screw feeder 5 and the air outlet pipe 6 form a heating channel, and the heating channel is used to heat the domestic waste.

[0032] The dispersing mechanism includes a motor bracket 81, a driving motor 82, a rotating shaft 83 and a rotating frame 84. The motor bracket 81 is welded to the top of the outer shell 3, and the driving motor 82 is connected to the motor bracket 81 by bolts. The rotating shaft 83 is fixedly connected to the output shaft of the driving motor 82. The rotating shaft 83 is rotatably connected to the air outlet pipe 6, and the rotating frame 84 is fixedly connected to the bottom of the rotating shaft 83.

[0033] The stirring mechanism includes a driving gear 91, a driven gear 92 and a stirring frame 93. The driving gear 91 is fixedly connected to the rotating shaft 83. Two stirring frames 93 are rotatably connected to the upper part of the air outlet pipe 6. A driven gear 92 is fixedly connected to each of the two stirring frames 93. The driven gear 92 meshes with the driving gear 91.

[0034] Each stirring rack 93 is located inside the feed pipe 4 , and the stirring rack 93 is used to stir the domestic waste so that the domestic waste can better contact with the air outlet pipe 6 .

[0035] At first, there is domestic garbage in the pyrolysis furnace 1, and the pyrolysis furnace 1 is in a low-oxygen environment. The staff starts the pyrolysis furnace 1, and the temperature in the pyrolysis furnace 1 rises rapidly. The temperature inside the pyrolysis furnace 1 reaches the temperature of domestic garbage pyrolysis. The domestic garbage is pyrolyzed and gasified to produce hydrogen and other gases. The hydrogen and other gases will be heated by the pyrolysis furnace 1, and the heated hydrogen and other gases will be discharged through the outlet pipe 6. Then the staff starts the exhaust fan 7, the screw feeder 5 and the drive motor 82. The domestic garbage moves into the feed pipe 4 under the push of the screw feeder 5, and the domestic garbage will be connected with the outlet pipe 6 in the feed pipe 4. The high temperature gas in the air outlet pipe 6 makes the temperature of the air outlet pipe 6 very high. The high temperature of the air outlet pipe 6 heats the domestic garbage, so that the moisture in the domestic garbage is heated and evaporated into water vapor, thereby reducing the moisture content of the domestic garbage, making it easy to be pyrolyzed. After being heated, the domestic garbage falls from the feed pipe 4 to the electric sealing door 2. The exhaust fan 7 is started to extract the water vapor, so that the shell 3 is kept dry. At the same time, the driving motor 82 rotates, which drives the rotating shaft 83, the rotating frame 84 and the driving gear 91 to rotate. The rotating frame 84 rotates to drop the garbage on the electric sealing door 2. The domestic garbage on the door 2 is scattered, and the domestic garbage is loosely spread on the electric sealing door 2. The rotation of the driving gear 91 will drive the driven gear 92 to rotate, and the rotation of the driven gear 92 will drive the stirring frame 93 to rotate. The rotation of the stirring frame 93 will stir the domestic garbage in the feeding pipe 4, so that the domestic garbage in the feeding pipe 4 can be more fully in contact with the exhaust pipe 6, so that the moisture in the domestic garbage can be more fully evaporated, making the domestic garbage drier. After the pyrolysis of the domestic garbage in the pyrolysis furnace 1 is completed, the staff opens the electric sealing door 2. Since the domestic garbage is loosely spread on the electric sealing door 2, the domestic garbage is loosely spread on the electric sealing door 2. The domestic waste is spread on the electric sealing door 2. When the electric sealing door 2 is opened, the domestic waste can enter the pyrolysis furnace 1 evenly. Then the staff closes the electric sealing door 2. The scattered domestic waste enters the pyrolysis furnace 1 without agglomeration. Moreover, the moisture content of the domestic waste is very low after heating and drying, so that the domestic waste can be more fully pyrolyzed, and the hydrogen production effect of the domestic waste is better. After the pyrolysis of the domestic waste in the pyrolysis furnace 1 is completed again, the previous steps are repeated. After the pyrolysis of all the domestic waste is completed, the staff turns off the screw feeder 5, the exhaust fan 7 and the drive motor 82.

[0036] Embodiment 2: Based on embodiment 1, Figure 4-Figure 5As shown, it also includes a toggle mechanism, which includes a guide frame 101, a pushing frame 102, a connecting rod 103 and a cover plate 104. The guide frame 101 is welded inside the shell 3, and a guide groove is opened on the guide frame 101. Three pushing frames 102 are slidably connected to the rotating frame 84, and a connecting rod 103 is welded to each pushing frame 102. Each connecting rod 103 is slidably connected to the guide groove of the guide frame 101. Three cover plates 104 are fixedly connected to the rotating frame 84, and each cover plate 104 is in contact with a pushing frame 102.

[0037] Each pushing frame 102 is provided with a plurality of stirring rods 115 , and the stirring rods 115 are used to further break up the domestic waste.

[0038] The rotation of the rotating frame 84 will drive the pushing frame 102, the connecting rod 103 and the cover plate 104 to rotate. The rotation of the connecting rod 103 will be squeezed by the guide groove of the guide frame 101, so that the connecting rod 103 will reciprocate along the guide groove. The reciprocating movement of the connecting rod 103 will drive the pushing frame 102 and the connecting rod 103 to reciprocate. The reciprocating movement of the pushing frame 102 will drive the stirring rod 115 to reciprocate, so that the reciprocating movement of the stirring rod 115 will further break up the domestic waste, making the domestic waste looser when entering the pyrolysis furnace 1, so that the domestic waste can be more fully pyrolyzed, thereby further improving the hydrogen production effect of domestic waste. Stopping the rotation of the rotating frame 84 will cause the pushing frame 102, the connecting rod 103 and the cover plate 104 to stop rotating and moving.

[0039] Embodiment 3: Based on embodiment 2, Figure 6-Figure 9 As shown, a pushing mechanism is also included, which includes a fixed rod 111, a sliding frame 112, a mobile frame 113 and a reciprocating threaded sleeve 114. A plurality of fixed rods 111 are welded to each stirring frame 93. A sliding frame 112 is slidably connected to a plurality of fixed rods 111 on the same stirring frame 93. A mobile frame 113 is welded to each sliding frame 112. Two reciprocating threaded sleeves 114 are welded to the air outlet pipe 6. Each reciprocating threaded sleeve 114 is threadedly connected to a mobile frame 113.

[0040] The sliding frame 112 is located inside the lower end of the feed pipe 4, and the sliding frame 112 is used to push the domestic garbage.

[0041] The rotation of the stirring frame 93 will drive the fixed rod 111, the sliding frame 112 and the mobile frame 113 to rotate. The rotation of the mobile frame 113 will squeeze the threads on the reciprocating threaded sleeve 114 and make the mobile frame 113 reciprocate. The reciprocating movement of the mobile frame 113 will drive the sliding frame 112 to reciprocate. The reciprocating movement of the sliding frame 112 will further stir the domestic waste in the feeding pipe 4, making the gaps of the domestic waste in the feeding pipe 4 larger, so that the water vapor generated after the domestic waste is heated can better flow out from the gaps in the domestic waste, so that the domestic waste can be drier, so that the domestic waste can be better pyrolyzed during the subsequent pyrolysis, so that the domestic waste can be more efficiently pyrolyzed to produce hydrogen. When the stirring frame 93 stops rotating, the fixed rod 111, the sliding frame 112 and the mobile frame 113 will stop moving.

[0042] Embodiment 4: Based on the embodiment 3, Fig.10 As shown, a filter screen 12 is also included, and a filter screen 12 is fixedly connected to the lower end of each feed pipe 4.

[0043] The filter screen 12 is fixed on the feed pipe 4 so that the water vapor generated after the domestic waste is heated can be discharged more easily.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
