DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] like Figure 1-Figure 5 As shown, an improved garbage pyrolysis hydrogen production device proposed in one embodiment of the present application includes: The furnace body 1 has a feed bin 101, a heat exchange bin 102 and an incineration bin 103 in order from top to bottom. The heat exchange bin 102 has a plurality of partitions 109 connected in an array along its inner wall. A ventilation column 104 is connected between the plurality of partitions 109. The ventilation column 104 is installed between the plurality of partitions 109 so that the heat exchange bin 102 forms a plurality of vertical slot channels. A gas-liquid separator 2 is installed in the ventilation column 104 for separating water vapor from the synthesis gas. A bearing mesh frame 105 is connected between the outer side of the ventilation column 104 and the partition 109. A diversion guide frame 106 located in the feed bin 101 is rotatably installed on the top of the ventilation column 104. The top structure of the furnace body 1 There is an exhaust port 107 and a discharge port 108 at the bottom. When the garbage enters the furnace body 1, it is first received by the diversion guide frame 106. By using its continuous rotation, the garbage can be diverted to different vertical slot channels in turn, and then received by the supporting mesh frame 105. The furnace body 1 is continuously heated and heated, and the garbage can be incinerated and broken, so that it falls into the incineration bin 103 below to continue to be piled up and heated. Such a structure can make the garbage evenly dispersed on the surrounding side of the ventilation column 104, increase the contact area with the furnace body 1, increase the heating speed and thus improve the pyrolysis efficiency. The ventilation column 104 arranged in the middle can make the synthetic gas generated by the garbage rise smoothly and ensure the circulation of the gas. The exhaust assembly 3 includes an air passing frame 301 fixedly connected to the top of the furnace body 1 and connected to the exhaust port 107. A rotating shaft 302 that movably penetrates the diverter guide frame 106 is rotatably installed in the air passing frame 301. A differential transmission member 4 is connected between the rotating shaft 302 and the diverter guide frame 106. An exhaust impeller 303 located in the air passing frame 301 is sleeved on the rotating shaft 302. A driving motor 304 connected to the rotating shaft 302 is installed on the upper end of the air passing frame 301. The driving motor 304 can not only drive the exhaust impeller 303 to rotate at a high speed to facilitate the extraction of synthetic gas generated by garbage, but also can link the diverter guide frame 106 through the differential transmission member 4 to make it rotate slowly and synchronously, thereby guiding the garbage and making the garbage evenly distributed, thereby ensuring the coordinated cooperation of the device; The preheating feed member 5 is installed on the top of the furnace body 1 and is connected to the feed bin 101 at an angle downward, and is used to preheat the garbage to remove part of the moisture in the garbage, improve the pyrolysis efficiency of the furnace body 1, and reduce the moisture content of the synthesis gas.

[0022] like Figure 2-Figure 3As shown, in some embodiments, a frustum frame 1041 is installed on the top of the ventilation column 104, and an array of vents 1042 are constructed on the inclined surface of the frustum frame 1041. The diverter guide frame 106 and the rotating shaft 302 are rotatably installed on the top surface of the frustum frame 1041. An air inlet mesh plate 1043 is fixedly connected to the bottom of the ventilation column 104. The frustum frame 1041 with the vent 1042 is installed on the top of the ventilation column 104, and the air inlet mesh plate 1043 is installed at the bottom thereof, which is mainly used to block the entry of block garbage to facilitate the circulation of synthetic gas, and the ventilation column 104 is arranged in the inner middle part of the furnace body 1 through the partition 109, which can separate the garbage on its surrounding side and facilitate its contact with the garbage, thereby conducting heat to improve the heating efficiency.

[0023] like Figure 4 As shown, in some embodiments, the gas-liquid separator 2 includes a plurality of frustum condensation mesh plates 201 arranged in an array along the height direction of the ventilation column 104, a plurality of annular groove plates 202 are arranged in an array inside the ventilation column 104, the annular groove plates 202 are sequentially distributed between the frustum frame 1041 and the bottom edge of the frustum condensation mesh plate 201, wherein a heat insulation block 203 is installed between two partitions 109, a manifold 204 connected to the plurality of annular groove plates 202 is installed on the ventilation column 104, the manifold 204 passes through the heat insulation block 203 and the furnace body 1, wherein the heat insulation block 203 is used to wrap the manifold 204 to prevent it from overheating and ensure smooth discharge of water, and when the garbage is diverted through the diversion guide frame 106, it will continuously scatter to each partition. 109, and constantly in contact with the side wall of the ventilation column 104, the garbage will exchange heat with the side wall of the ventilation column 104, the side wall temperature of the ventilation column 104 will decrease, and the synthesis gas generated by pyrolysis in the incineration bin 103 will rise through the ventilation column 104, and the high-temperature gas will contact each cone condensation mesh plate 201 when passing through the ventilation column 104, thereby condensing the water vapor therein, and the condensed water will gradually gather and fall into the annular groove plate 202 for collection, and will be discharged through the manifold 204 for centralized collection and treatment, so as to avoid affecting the subsequent separation and processing operation of the synthesis gas and increase safety. In addition, the structure of the ventilation column 104 can circulate heat with the garbage to improve the overall heating efficiency.

[0024] like Figure 2 and Figure 6As shown, in some embodiments, the diversion guide frame 106 includes a rotating drum 1061 rotatably installed on the top of the ventilation column 104, and a plurality of vertical plates 1062 equal to the number of partitions 109 are constructed in a circular array on the outer side of the rotating drum 1061, and fan-shaped mesh plates 1063 are connected between each of the vertical plates 1062. Both ends of the fan-shaped mesh plates 1063 are respectively constructed with discharge ports 1064 between the furnace body 1 and the rotating drum 1061. The fan-shaped mesh plates 1063 are arranged between the vertical plates 1062 to separate and receive the garbage dropped from the preheating feed piece 5, and the garbage is gradually scattered between the partitions 109 by centrifugal force during the rotation of the rotating drum 1061, so that the garbage is evenly distributed on the outer wall of the ventilation column 104, thereby ensuring the smooth heat exchange and increasing safety. At the same time, the contact area between the garbage and the furnace body 1 can also be increased, thereby improving the pyrolysis efficiency.

[0025] like Figure 2 and Figure 5 As shown, in some embodiments, the air frame 301 is constructed with two air outlets 3011, one of the air outlets 3011 is connected to a circulation pipe 3012 connected to the incineration chamber 103, an arc-shaped rotating plate 3013 is rotatably installed on the inner wall of the air frame 301 to block one of the air outlets 3011, the arc-shaped rotating plate 3013 is connected to an arc-shaped rack 3014, an adjustment motor 3015 is installed in the air frame 301, and the output shaft of the adjustment motor 3015 is connected to a driving gear 301 meshed with the arc-shaped rack 3014. 6. It should be noted that the two air outlets 3011 on the air frame 301 are used to discharge gas, one of which is connected to the subsequent equipment, and the other is connected to the incineration chamber 103 through the circulation pipe 3012. When the arc-shaped rotating plate 3013 closes one of them, the gas circulates in the equipment, which can accelerate the internal heating rate and thus improve the pyrolysis efficiency. The opening and closing operation only requires adjusting the motor 3015 to control the meshing rotation of the driving gear 3016 and the arc-shaped rack 3014. The automatic adjustment can be conveniently switched according to the needs of the equipment, thereby increasing the flexibility of the device.

[0026] like Figure 6-Figure 7As shown, in some embodiments, the differential transmission member 4 includes a ring plate 401 fixedly connected to the rotating shaft 302, and a plurality of balls 402 are arranged in an array along the circumference of the bottom of the ring plate 401. Two buffer rebound members 403 that are arranged opposite to each other and are used to abut the balls 402 are installed on the top of the rotating drum 1061. The traditional differential transmission relies on large and small gears for transmission. This structure not only occupies a large space and is inconvenient to install, but also cannot produce an excessively large speed ratio. By the balls 402 abutting against the buffer rebound member 403, the protrusion of the buffer rebound member 403 can be used to abut and rub against the balls 402, so that when in contact, the rotating shaft 302 is used to drive the rotating drum 1061 to rotate a certain distance, which can produce a large speed difference, so that The diverter guide frame 106 rotates slowly as a whole, and compared with the traditional gear transmission, the faster the rotation speed of the shaft 302 is, the slower the rotation speed of the drum 1061 is due to the small friction. The slower the rotation speed of the shaft 302 is, the greater the contact friction between the buffer rebound part 403 and the ball 402 is, and the faster the rotation speed of the drum 1061 is. In this way, the exhaust impeller 303 can be slowly rotated when the furnace body 1 starts to feed, so as to avoid gas extraction, and the garbage feeding speed can be accelerated, and the amount of garbage received and dumped by the diverter guide frame 106 is increased. When the furnace body 1 runs to start pyrolyzing the garbage, the exhaust impeller 303 is rotated at a high speed, the gas is extracted, and the garbage is slowly added. The diverter guide frame 106 rotates slowly and reduces the amount of garbage scattered downward to avoid incomplete pyrolysis of the garbage below.

[0027] like Figure 7As shown, in some embodiments, the buffer rebound member 403 includes an insert 4031 configured on the top of the rotating cylinder 1061, a sliding hole 4032 is configured in the insert 4031, an air inlet 4033 connected to the sliding hole 4032 is configured at the bottom of the insert 4031, an active cavity 4034 located at the top of the sliding hole 4032 is configured in the insert 4031, and a plunger block 4034 having a height less than that of the active cavity 4034 is slidably installed in the sliding hole 4032. 35, a support spring 4036 is connected between the plunger block 4035 and the bottom of the slide hole 4032, and a convex rod 4037 is fixedly connected to the top of the plunger block 4035 and slides through the top of the insert cylinder 4031. It should be noted that in the initial state, the plunger block 4035 is in the active cavity 4034, and the convex rod 4037 protrudes from the upper surface of the rotating cylinder 1061 and can contact the ball 402. When the ball 402 contacts the convex rod 4037, it will not only drive the rotating cylinder 1061 to rotate, but also can cause the rotating cylinder 1061 to rotate. The cylinder 1061 rotates and squeezes the protruding rod 4037 to shrink into the insert cylinder 4031. At this time, the plunger block 4035 is tightly inserted into the sliding hole 4032. The gas in the sliding hole 4032 is discharged through the air inlet 4033, and the support spring 4036 is squeezed. When the ball 402 passes over the protruding rod 4037, the elastic force of the support spring 4036 pushes the plunger block 4035 upward, and the diameter of the air inlet 4033 is much smaller than that of the sliding hole 4032. diameter, so the air intake speed of the air inlet hole 4033 is slow, and the plunger block 4035 will slowly move up until it completely enters the movable chamber 4034. At this time, the plunger block 4035 will lose the pulling force of the negative pressure in the sliding hole 4032, and the supporting spring 4036 can quickly push it, so that the protruding rod 4037 pops out, which can nearly horizontally contact with the ball 402, thereby increasing the pushing force of the ball 402 on the rotating drum 1061 and ensuring the smooth rotation of the rotating drum 1061.

[0028] like Figure 2 and Figure 8 As shown, in some embodiments, the preheating feed member 5 includes an inclined frame 501 fixedly connected to the top corner of the furnace body 1, and a conical feed port 502 arranged between the two vertical plates 1062 is constructed in the inclined frame 501. A crusher 503 is fixedly connected to the top of the inclined frame 501, and an openable pre-storage frame 504 is fixedly connected to the top of the crusher 503. It should be noted that the bottom opening size of the conical feed port 502 is smaller than the distance between the two vertical plates 1062, so that the garbage can be crushed by the crusher 503 and fall smoothly onto the fan-shaped mesh plate 1063. The pre-storage frame 504 is set on the top of the crusher 503, which is mainly used to seal the feed port of the crusher 503, and is only opened when garbage is added, so as to reduce gas leakage and increase safety.

[0029] like Figure 1-Figure 2 and Figure 8As shown, in some embodiments, the pre-storage frame 504 includes a rectangular frame 5041 fixedly connected to the upper end of the pulverizer 503, and the top of the rectangular frame 5041 is turned over and installed with two mutually buckled sealing plates 5042, and the opposite ends of the two sealing plates 5042 are both constructed with a rotating rod 5043 hinged on the rectangular frame 5041, and a torsion spring 5044 is connected between one end of the rotating rod 5043 and the rectangular frame 5041, and the top of the rectangular frame 5041 is connected to a conical bucket 5045, and the rectangular frame 5041 is connected to the incineration bin 103. It is connected to a waste heat heating component 6. It should be noted that in the initial state, the torsion spring 5044 generates torque on the two rotating rods 5043, and the two sealing plates 5042 are in a parallel docking state. At this time, the rectangular frame 5041 can be sealed, and when garbage needs to be added, the garbage can be poured into the conical bucket 5045. When the garbage is heavy enough, the two sealing plates 5042 can be pushed to flip over by themselves, so that the garbage can slide into the crusher 503. In this way, the operation of uniform feeding in batches can be realized, thereby increasing the functionality of the device.

[0030] like Figure 1 and Figure 8 As shown, in some embodiments, the waste heat heating component 6 includes a hot air pipe 601 fixedly connected to the furnace body 1 and connected to the incineration bin 103, the top of the hot air pipe 601 is connected to a circular pipe 602, and the inner wall of the circular pipe 602 is constructed with a ventilation mesh pipe 603 connected to the side and top surfaces of the rectangular frame 5041. It should be noted that the ventilation mesh pipe 603 is arranged on the top and side middle parts of the rectangular frame 5041, which can effectively prevent moisture from entering the incineration bin 103 through the ventilation mesh pipe 603, thereby increasing safety. The heat in the incineration bin 103 is transferred to the rectangular frame 5041 through the hot air pipe 601 and the circular pipe 602, which can not only heat the inside of the rectangular frame 5041, but also preliminarily reduce the water content in a part of the garbage and improve the subsequent pyrolysis efficiency. Moreover, no additional heating source is required, and the heat inside the furnace body 1 is used for supply, thereby saving energy.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
