Description

Technical Field

[0001] This invention relates to the field of biomass gasification and combustion technology, and more particularly to a horizontal biomass gasification and co-production equipment. Background Technology

[0002] Biomass gasification combustion is a high-quality and clean utilization of biomass energy, which has received support and encouragement from relevant national departments.

[0003] Existing biomass gasifiers are mainly divided into fluidized bed (including bubbling type) gasifiers and fixed bed gasifiers (mainly including top-suction and bottom-suction types). Horizontal biomass gasification equipment is a new technology that has been expanded and gradually promoted in recent years. Compared with fluidized bed and fixed bed gasifiers, the advantages of horizontal gasifiers are: 1. Lower equipment height, facilitating user installation. 2. Better tolerance for biomass feedstocks, even with higher moisture content, and a wider range of requirements for the size of broken pieces compared to fluidized bed and fixed bed gasifiers. The horizontal biomass gasification and co-production gasifier is developed based on existing horizontal biomass gasifiers.

[0004] Existing horizontal biomass gasifiers have the following drawbacks: First, if high-quality biomass feedstocks are produced through full gasification, their potential value is not optimized. For example, high-quality fruit shells, fruit trees, and bamboo are excellent biochar feedstocks; only by adopting co-production of gas and biochar can the value of these feedstocks be better enhanced. Second, while current horizontal biomass gasifiers use high-temperature gasification, a small amount of biochar residue is still discharged, forming solid waste. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where high-quality biomass raw materials do not have their potential value optimized when produced through full gasification, and where horizontal biomass gasifiers employ high-temperature gasification. The invention proposes a horizontal biomass gasification and co-production equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A horizontal biomass gasification and co-production equipment includes a co-production gasifier. A feeding screw conveyor is fixedly connected to one side of the co-production gasifier, and a hopper is fixedly connected to the top side of the feeding screw conveyor. The hopper and the feeding screw conveyor are used to feed materials into the interior of the co-production gasifier. A feed cover plate is hinged to one end of the feeding screw conveyor. A guide plate is fixedly installed on the top inner wall of the co-production gasifier, which divides the interior space of the co-production gasifier into two parts: a drying chamber near the feeding screw conveyor and a combustion chamber away from the feeding screw conveyor. A conveying assembly for conveying materials is provided on the inner wall of the co-production gasifier. The same set of gas supply components for supplying gas is provided on both sides of the carbon-gas cogeneration gasifier. The carbon-gas cogeneration gasifier has a discharge port at the end away from the feeding screw conveyor, and a discharge assembly for discharging material is provided on one side of the carbon-gas cogeneration gasifier.

[0009] In one possible design, the discharge assembly includes a carbon discharge cover plate hinged to one side of the carbon-gas cogeneration gasifier, the carbon discharge cover plate being used to seal the discharge port.

[0010] In one possible design, the discharge assembly includes a discharge box fixedly installed on one side of the carbon-gas cogeneration gasifier, one side of the discharge box being connected to the discharge port, an inclined plate being fixedly installed on the bottom inner wall of the discharge box, a cooling box being fixedly installed at one end of the discharge box, a material hole being opened inside the cooling box and being connected to the discharge box, and a cooling assembly for cooling the carbon being provided on the outside of the cooling box. A discharge assembly for assisting material discharge is fixedly installed at one end of the cooling box.

[0011] In one possible design, the cooling assembly includes a cavity formed inside the cooling tank, the cavity surrounding the material inlet, a coolant outlet pipe fixedly installed at the top of the cooling tank, and a coolant inlet pipe fixedly installed at the bottom of the cooling tank, both of which are connected to the cavity.

[0012] In one possible design, the discharge assembly includes a connecting flange fixedly installed at one end of the cooling box, a communicating material cylinder fixedly installed at one end of the connecting flange, a communicating discharge pipe fixedly connected to one side of the bottom of the material cylinder, a support base fixedly installed at the top of the material cylinder, a servo motor fixedly installed at the top of the support base, a fixing plate fixedly installed on the top inner wall of the cooling box, a fixing bearing seat fixedly installed at the bottom of the fixing plate, the fixing bearing seat and the internal rotation of the material cylinder are connected by the same rotating shaft, synchronous pulleys are fixedly sleeved on the outer wall of the cooling box and the output shaft of the servo motor, the outer walls of the two synchronous pulleys are driven by the same synchronous belt, and a spiral blade is fixedly sleeved on the outer wall of the rotating shaft, the pitch of the spiral blade gradually decreasing.

[0013] In one possible design, two dust covers are also included. Each of the two dust covers has a connecting plate fixedly installed on one side. The two connecting plates are fixedly connected by screws. Ventilation holes are provided on one side of each dust cover. One of the dust covers is fixedly installed on one side of the support base. The two dust covers are spliced ​​together to protect the timing pulley and timing belt.

[0014] In one possible design, an induced draft fan is fixedly installed on the top of one side of the carbon-gas cogeneration gasifier. The outlet of the induced draft fan is fixedly connected to a combustible gas outlet. The inlet of the induced draft fan is connected to the carbon-gas cogeneration gasifier. An observation window is provided on one side of the carbon-gas cogeneration gasifier. Multiple drilling holes are provided on the side of the carbon-gas cogeneration gasifier. Multiple slag removal ports are provided at the bottom of the carbon-gas cogeneration gasifier.

[0015] In this application, the horizontal biomass gasifier is a rectangular furnace body placed horizontally. A feed inlet is located at the top front of the furnace body, and a sealed rotary valve is installed at the feed inlet. Inside the furnace body, a reciprocating feeding grate is installed to receive the biomass material fed in from the feed inlet, initiating the drying and volatilization process of the biomass raw material. A combustion chamber is located at the rear end of the reciprocating feeding grate. A guide plate is installed in the furnace body in front of the combustion chamber and above the reciprocating feeding grate. A gap is left between the front end of the guide plate and the front side wall of the furnace body to allow the biomass material fed in from the feed inlet to fall smoothly onto the reciprocating feeding grate. At this time, a channel connecting the guide plate and the reciprocating feeding grate to the combustion chamber is formed. A combustible gas outlet is located on the side wall of the furnace body above the guide plate, and an induced draft fan is installed at the combustible gas outlet. A char outlet is located on the side wall of the furnace body below and behind the reciprocating feeding grate. An air inlet is located on the side wall of the furnace body. The air inlet introduces combustion-supporting gas into the combustion chamber. As the reciprocating grate conveys the received biomass through the channel to the combustion chamber for combustion, the high-temperature flue gas generated in the combustion chamber moves forward against the direction of biomass conveying under the action of the induced draft fan, contacting the biomass and causing it to heat and dry, thus generating combustible gas. The combustible gas moves forward along the channel and, after passing through the material drop gap, is discharged from the combustible gas outlet.

[0016] In another discharge design, a discharge box can be fixedly installed at the tail end of the carbon-gas cogeneration gasifier. Carbon is fed into the interior of the feed hole through the inclined plate. Coolant is introduced through the coolant inlet pipe, filling the cavity, and then discharged through the coolant outlet pipe, thus cooling the carbon inside. By starting the servo motor, the output shaft of the servo motor drives the rotating shaft to rotate through the synchronous pulley and synchronous belt. The rotating shaft drives the external spiral blade to rotate. The spiral blade is designed with a "variable pitch" structure, that is, the pitch is wider near the feed end (furnace body side) and gradually decreases near the discharge end (external). When the rotating shaft rotates to discharge carbon, the volume of biochar is physically compressed during the conveying process due to the smaller pitch, forcibly forming a high-density "material plug" at the end of the discharge pipe. This "material plug" itself becomes a physical barrier, which not only blocks outside air from entering the furnace to oxidize the high-temperature carbon, but also prevents the leakage of combustible gas inside the furnace. At the same time, it is cooled by the action of the water-cooled wall, realizing "cold carbon discharge". Beneficial effects

[0017] By coordinating the hopper, the feeding screw conveyor and the reciprocating grate body, stable and uniform material transportation is achieved. The guide plate zoning design ensures the continuity of the drying and gasification process. All components work together to achieve efficient gas-carbon co-production, fully tapping the value of biomass raw materials. The design of multiple air supply ducts with regulating valves achieves uniform gas distribution and precise control, ensuring sufficient gasification reaction and improving the quality of combustible gas; the plug structure formed by the variable pitch spiral blades blocks air from entering and gas from leaking out, and together with the surrounding cooling components, cold char is discharged from the furnace, avoiding oxidation and loss of char and improving the quality of char. Carbon outlet cover, dust cover and other structures ensure the sealing and protection performance of the equipment, avoid safety hazards such as gas leakage, dust interference and exposed parts, and the setting of observation window, drilling hole and slag cleaning port improves the convenience of operation and maintenance, facilitates timely handling of abnormalities and cleaning of residues, and reduces the risk of failure. It features both intermittent and continuous discharge structures to meet different production needs. The inclined plate and anti-blockage design prevents material stagnation and accumulation. The overall structure is reasonable, easy to operate, extends the service life of the equipment, and reduces maintenance costs. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment: Refer to Figure 1-6 This equipment includes a carbon-gas cogeneration gasifier 1. A feeding screw conveyor 9 is fixedly connected to one side of the carbon-gas cogeneration gasifier 1. A hopper 8 is fixedly connected to the top of the feeding screw conveyor 9. The hopper 8 and the feeding screw conveyor 9 are used to feed materials into the interior of the carbon-gas cogeneration gasifier 1. A feed cover plate 5 is hinged to one end of the feeding screw conveyor 9. A guide plate 3 is fixedly installed on the inner top wall of the carbon-gas cogeneration gasifier 1. The guide plate 3 divides the internal space of the carbon-gas cogeneration gasifier 1 into two sections: one space closer to the feeding screw conveyor 9 is a drying chamber, and the other space farther from the feeding screw conveyor 9 is a combustion chamber. The inner wall is equipped with a conveying assembly for conveying materials. Both sides of the carbon-gas cogeneration gasifier 1 are equipped with the same set of gas feeding assemblies for feeding gas. The end of the carbon-gas cogeneration gasifier 1 away from the feeding screw conveyor 9 is equipped with a discharge port. One side of the carbon-gas cogeneration gasifier 1 is equipped with a discharge assembly for discharging materials. A carbon collection tank 14 is fixedly installed on one side of the bottom of the carbon-gas cogeneration gasifier 1. The carbon collection tank 14 is used to receive the materials discharged by the discharge assembly. A carbon screw conveyor 16 is fixedly installed inside the carbon collection tank 14. A connected carbon storage bin 15 is fixedly installed on one side of the bottom of the carbon screw conveyor 16. The carbon screw conveyor 16 is used to discharge materials into the interior of the carbon storage bin 15. Specifically, the carbon-gas cogeneration gasifier 1 is a horizontally placed rectangular furnace body. A material drop gap is left between the front end of the guide plate 3 and the front side wall of the furnace body to allow the biomass material fed from the feeding port to fall smoothly onto the conveying assembly. The guide plate 3 and the conveying assembly form a channel connected to the combustion chamber. In order to achieve the smooth discharge of combustible gas, an induced draft fan 6 is fixedly installed on the top of one side of the carbon-gas cogeneration gasifier 1. The air outlet of the induced draft fan 6 is fixedly connected to a combustible gas outlet 7. The air inlet of the induced draft fan 6 is connected to the carbon-gas cogeneration gasifier 1. When the conveying assembly conveys the received biomass material to the combustion chamber for combustion through the channel, the high-temperature flue gas generated in the combustion chamber will move forward against the biomass material conveying direction under the action of the induced draft fan 6 and come into contact with the biomass material, so that the biomass material is heated and dried, and combustible gas is generated. The combustible gas will move forward along the channel and be discharged from the combustible gas outlet 7 after passing through the material drop gap. Preferably, the carbon-gas cogeneration gasifier 1 is made of Q235 steel plate by welding to ensure that the furnace body has sufficient structural strength and high temperature resistance.

[0022] The conveying assembly includes a reciprocating grate body 19 fixedly installed on the inner wall of the carbon-gas cogeneration gasifier 1. A reciprocating grate motor 10 is fixedly installed on one side of the carbon-gas cogeneration gasifier 1. The reciprocating grate motor 10 is used to provide power to the reciprocating grate body 19. A heat insulation pad is provided between the reciprocating grate motor 10 and the mounting surface of the carbon-gas cogeneration gasifier 1. A heat dissipation cover is installed on the outside of the reciprocating grate motor 10. A carbon discharge guide plate 18 is fixedly installed at one end of the reciprocating grate body 19. The carbon discharge guide plate 18 is used in conjunction with the discharge port. Specifically, the output shaft of the reciprocating grate motor 10 is fixedly connected to the drive end of the reciprocating grate body 19 via a coupling. Starting the reciprocating grate motor 10 will drive the reciprocating grate body 19 to reciprocate, thereby achieving stable and uniform material conveying in the furnace and ensuring that the material fully undergoes the drying and gasification process. The carbon discharge guide plate 18 is inclined, with one end fixedly connected to the end of the reciprocating grate body 19 and the other end extending to the discharge port. It can guide the carbon material to be accurately discharged to the subsequent components, avoiding the accumulation of carbon material in the furnace and ensuring smooth discharge.

[0023] The gas supply assembly includes an air inlet pipe 12 fixedly installed on the outer wall of the carbon-gas cogeneration gasifier 1. A blower 11 is fixedly installed on one side of the carbon-gas cogeneration gasifier 1. The air outlet of the blower 11 is connected to the air inlet pipe 12. The blower 11 is fixedly installed on one side of the carbon-gas cogeneration gasifier 1 by a bracket with a heat insulation layer. The distance between the bracket and the side wall of the gasifier body is not less than 15cm. Multiple interconnected air supply pipes 20 are fixedly installed on the side of the air inlet pipe 12. One end of the air supply pipe 20 extends into the interior of the carbon-gas cogeneration gasifier 1. An air regulating valve 21 is fixedly installed on the air supply pipe 20. Specifically, the blower 11 is fixed to the mounting bracket on one side of the carbon-gas cogeneration gasifier 1 by bolts. The outlet of the blower 11 is fixedly connected to the inlet pipe 12 through a flange. Multiple air supply pipes 20 are evenly distributed along the length of the inlet pipe 12, and one end of the air supply pipe 20 extends into the interior of the carbon-gas cogeneration gasifier 1, facing different areas of the combustion chamber and the drying chamber. The air regulating valve 21 is a manual butterfly valve. The opening of the air supply pipe 20 can be adjusted by rotating the valve stem, so as to realize the flexible adjustment of the gas delivery volume of each air supply pipe 20, so as to accurately match the gas supply in the furnace with the reaction process and ensure the sufficiency of the gasification reaction.

[0024] The discharge assembly includes a carbon discharge cover 17 hinged to one side of the carbon-gas cogeneration gasifier 1, which is used to seal the discharge port. Specifically, the carbon discharge cover 17 is hinged to the side wall of the carbon-gas cogeneration gasifier 1 via a hinge. The edge of the carbon discharge cover 17 is provided with a sealing gasket. When the carbon discharge cover 17 is closed, the sealing gasket fits tightly against the edge of the discharge port, which can maintain the sealed environment inside the furnace, ensure the temperature and pressure conditions required for the reaction inside the furnace, and avoid safety hazards caused by the leakage of combustible gas. During discharge, the carbon material can be discharged by opening the carbon discharge cover 17. The operation is simple and can be adapted to intermittent discharge requirements.

[0025] Furthermore, the cooling assembly includes a cavity 31 formed inside the cooling box 24, surrounding the material hole 30. A coolant outlet pipe 25 is fixedly installed on the top of the cooling box 24, and a coolant inlet pipe 23 is fixedly installed on the bottom of the cooling box 24.

Specifically, the coolant inlet pipe 23 and the coolant outlet pipe 25 are fixedly connected to the cooling box 24 by welding, and both the coolant inlet pipe 23 and the coolant outlet pipe 25 are equipped with pipe joints for connecting to an external cooling circulation system. After the coolant is introduced through the coolant inlet pipe 23, it fills the cavity 31, flows through the entire surrounding area, and is discharged from the coolant outlet pipe 25, forming a complete cooling cycle. This surrounding cooling structure can fully contact and exchange heat with the charcoal, greatly improving the cooling efficiency and ensuring that the high-temperature charcoal cools down rapidly during transportation.

[0026] An observation window 2 is provided on one side of the carbon-gas cogeneration gasifier 1, and multiple drilling holes 4 are provided on the side of the carbon-gas cogeneration gasifier 1. Multiple slag removal ports 13 are provided at the bottom of the carbon-gas cogeneration gasifier 1. Specifically, the observation window 2 is made of high-temperature resistant quartz glass and is embedded in the side wall of the carbon-gas cogeneration gasifier 1, which allows the operator to observe the reaction in the furnace in real time, and promptly detect and deal with abnormal problems. The multiple drilling holes 4 are evenly distributed along the length of the carbon-gas cogeneration gasifier 1, and each drilling hole 4 is equipped with a sealing cover. Opening the sealing cover allows the drill rod to be inserted into the furnace to check the material accumulation status and facilitate unblocking operations. The multiple slag removal ports 13 are evenly arranged at the bottom of the carbon-gas cogeneration gasifier 1, and each slag removal port 13 is hinged with a sealing door. Regularly opening the sealing door allows for the cleaning of residues in the furnace, preventing residue accumulation from affecting reaction efficiency and equipment operation stability.

[0027] This application can be used in the field of biomass gasification combustion, or in other fields applicable to this application.

[0028] In another embodiment: Reference Figure 1-6This is a horizontal biomass gasification and co-production equipment used in the field of biomass gasification and combustion. The structure of this embodiment is basically the same as that of the previous embodiment, except that: the discharge component includes a discharge box 22 fixedly installed on one side of the co-production gasifier 1. One side of the discharge box 22 is connected to the discharge port. An inclined plate 29 is fixedly installed on the bottom inner wall of the discharge box 22. A cooling box 24 is fixedly installed at one end of the discharge box 22. A material hole 30 is opened inside the cooling box 24 and is connected to the discharge box 22. A cooling component for cooling the carbon is provided on the outside of the cooling box 24. A discharge component for assisting the material discharge is fixedly installed at one end of the cooling box 24. Specifically, the discharge box 22 is fixedly connected to the side wall of the carbon-gas cogeneration gasifier 1 by bolts. A sealing gasket is provided at the connection between the discharge box 22 and the discharge port. The inclined plate 29 is fixed at a 30-degree angle to the bottom inner wall of the discharge box 22. After the carbon material is discharged from the discharge port, it falls into the discharge box 22 and smoothly enters the interior of the material hole 30 under the guidance of the inclined plate 29, avoiding the carbon material from accumulating in the discharge box 22. The discharge assembly includes a connecting flange 26 fixedly installed at one end of the cooling box 24. A connected material cylinder 27 is fixedly installed at one end of the connecting flange 26. A connected discharge pipe 28 is fixedly connected to one side of the bottom of the material cylinder 27. A support base 36 is fixedly installed at the top of the material cylinder 27. A servo motor 38 is fixedly installed in the cooling box 24. The servo motor 38 is equipped with a heat dissipation shell, and a heat dissipation channel is opened inside the support base 36. The heat dissipation channel is connected to the ventilation hole 39 of the dust cover 37 to form a heat dissipation airflow channel. A fixed plate 35 is fixedly installed on the top inner wall of the cooling box 24. A fixed bearing seat 32 is fixedly installed at the bottom of the fixed plate 35. The fixed bearing seat 32 and the internal rotation of the material cylinder 27 are connected by the same rotating shaft 34. Synchronous pulleys 40 are fixedly sleeved on the outer wall of the cooling box 24 and the output shaft of the servo motor 38. The same synchronous belt 42 is sleeved on the outer wall of the two synchronous pulleys 40. A spiral blade 33 is fixedly sleeved on the outer wall of the rotating shaft 34. The pitch of the spiral blade 33 gradually decreases. Specifically, the connecting flange 26 connects the cooling box 24 and the material cylinder 27 by bolts, the support base 36 is fixed to the top of the material cylinder 27 by welding, the servo motor 38 is fixed to the top of the support base 36 by bolts, the fixing plate 35 is welded to the inner wall of the cooling box 24, the fixed bearing seat 32 is fixed to the bottom of the fixing plate 35 by bolts, and the two ends of the rotating shaft 34 are rotatably connected to the fixed bearing seat 32 and the inner wall of the material cylinder 27 by bearings, respectively, to ensure that the rotating shaft 34 can rotate stably.The servo motor 38 is started. The output shaft of the servo motor 38 drives the rotating shaft 34 to rotate via the synchronous pulley 40 and the synchronous belt 42. The transmission is stable and the power transmission efficiency is high. The rotating shaft 34 drives the spiral blade 33 to rotate. The pitch of the spiral blade 33 gradually decreases from the end near the cooling box 24 to the end near the discharge pipe 28, so that the charcoal is gradually compressed during the conveying process, forming a high-density plug. This plug can effectively block the outside air from entering the furnace and prevent the leakage of combustible gas inside the furnace, ensuring the stability of the reaction environment inside the furnace. In conjunction with the cooling components, it achieves cold charcoal discharge and avoids charcoal oxidation and loss. Preferably, the spiral blade 33 is made of 304 stainless steel, which has good corrosion resistance and wear resistance.

[0029] In addition, the equipment includes two dust covers 37, each with a connecting plate 41 fixedly installed on one side. The two connecting plates 41 are connected by screws. Ventilation holes 39 are provided on one side of each dust cover 37. One dust cover 37 is fixedly installed on one side of the support base 36. The two dust covers 37, when joined together, protect the synchronous pulley 40 and the synchronous belt 42. Specifically, the dust covers 37 are made of plastic. One dust cover 37 is fixed to one side of the support base 36 with bolts, and the two connecting plates 41 are connected by Phillips head screws, thus achieving the joint fixation of the two dust covers 37. The joined dust covers 37 completely enclose the synchronous pulley 40 and the synchronous belt 42, preventing dust from entering the transmission components and affecting the transmission effect. They also prevent exposed components from causing safety hazards during transmission. The ventilation holes 39 ensure ventilation and heat dissipation inside the protective enclosure, preventing heat buildup from affecting the service life of the components.

[0030] During the operation of this equipment, it is necessary to regularly add grease to the moving parts of the reciprocating grate body 19, the mating parts of the rotating shaft 34 and the fixed bearing seat 32, regularly clean the dust in the air supply pipe 20 and the residual carbon in the material cylinder 27, and regularly check the tension and wear of the synchronous belt 42 and replace it in time to ensure the long-term stable operation of the equipment.

[0031] It also includes a PLC controller, which is electrically connected to the drive motor of the feeding screw conveyor 9, the reciprocating grate motor 10, the blower 11, the induced draft fan 6, the drive motor of the carbon screw conveyor 16, and the servo motor 38, respectively, to control the coordinated operation of each component.

[0032] However, as is well known to those skilled in the art, the working principles and wiring methods of the induced draft fan 6, servo motor 38, blower 11, carbon screw conveyor 16, feeding screw conveyor 9 and reciprocating grate motor 10 are all conventional means or common knowledge, and will not be described in detail here.
