Description

Technical Field

[0001] This application relates to the field of biomass power generation technology, specifically to biomass power generation devices. Background Technology

[0002] Biomass power generation technology is a thermal power generation technology that uses biomass and its processed solid, liquid, and gaseous forms as fuel. The generators can be gas engines, Stirling engines, gas turbines, or steam turbines, depending on the type of fuel, temperature, and power output.

[0003] An existing patent (publication number: CN218209505U) discloses a biomass power generation device, which relates to the field of biomass power generation technology. The device includes a boiler, in which metal plates are fixedly connected to the middle of the inner surfaces on both sides of the boiler, and a ceramic heat insulation plate is provided at the bottom of the inner surface of the boiler. By setting up the ceramic heat insulation plate and heat insulation cotton, cold water is poured onto the top of the metal plate, and the heat generated by the combustion of biomass materials causes the poured water to boil and generate steam. The ceramic heat insulation plate and heat insulation cotton ensure the concentration of heat, and the gas outlet facilitates the emission of smoke and dust generated by combustion. The surface of the gas outlet is immersed in liquid, which facilitates the absorption of heat from the smoke and dust by the liquid, thereby achieving effective heat recovery.

[0004] The device in the aforementioned comparative document did not pre-treat the biomass material, which resulted in the biomass material not reacting sufficiently during processing. Furthermore, the biomass material may clog the feed inlet during feeding. To address these issues, a biomass power generation device has been proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a biomass power generation device. By pulverizing biomass and using a feeding auger, it can effectively avoid problems such as clogging and incomplete reaction, while also making reasonable use of waste heat and improving energy utilization.

[0006] To achieve the above objectives, this application provides the following technical solution: a biomass power generation device, comprising a gasifier body, a pretreatment mechanism, and a slag discharge mechanism. The gasifier body includes a gasifier shell and a gasifier lining fixedly connected to the inner wall of the gasifier shell. A spiral pipe is fitted around the outer side of the gasifier lining, and both ends of the spiral pipe are connected to conveying pipes. The pretreatment mechanism includes a pretreatment box, and one end of each of the two conveying pipes is connected to the interior of the pretreatment box. Two crushing rollers are rotatably fitted on the top of the pretreatment box, and a planar gear is fixedly connected to the shaft end of each crushing roller. A first servo motor is fixedly connected to the outer surface of the pretreatment box, and the output shaft end of the first servo motor is fixedly connected to one end of the corresponding crushing roller. One end of the pretreatment box is connected to a feed pipe, and the output end of the feed pipe is fixedly connected to the inner wall of the gasifier lining. A second servo motor is fixedly connected to one side of the feed pipe, and a feeding auger is fixedly connected to the output shaft end of the second servo motor.

[0007] Through the above scheme, the gasifier body and pretreatment mechanism work together to achieve structural optimization and energy closed-loop design, simplifying the device structure while improving efficiency. Biomass can be crushed by two rotating crushing rollers, allowing it to fully undergo gasification within the gasifier lining. The second servo motor and feeding auger ensure smoother transport of the crushed biomass to the gasifier lining, reducing the risk of blockage. After gasification within the lining, residual heat can be transferred to the pretreatment box via spiral pipes and conveying pipes to dry the biomass inside, improving energy utilization. Finally, the slag removal mechanism removes residue from the gasifier lining.

[0008] Furthermore, the spiral pipe is located between the gasifier shell and the gasifier lining, and one end of each of the two conveying pipes penetrates the gasifier shell and extends to the outside of the gasifier shell.

[0009] The above scheme limits the location of the spiral pipe and the conveying pipe, enabling the recovery of waste heat generated by the gasification reaction inside the gasifier lining, making it more practical.

[0010] Furthermore, a gasifying agent inlet pipe and a gas outlet pipe are installed on the top of the gasifier lining, and the tops of the gasifying agent inlet pipe and the gas outlet pipe both penetrate the gasifier shell and extend to the top of the gasifier shell.

[0011] The above scheme allows for the addition of a gasifying agent to the interior of the gasifier lining via the gasifying agent inlet pipe, promoting the gasification reaction. The gas outlet pipe allows for the extraction of the combustible gas generated inside the gasifier lining.

[0012] Furthermore, a feeding port is installed on the top of the pretreatment box, and the outer surface of the feeding pipe is fixedly connected to the inner wall of the gasifier shell.

[0013] The above scheme allows biomass materials to be conveniently fed into the pretreatment box for pretreatment through the feeding port. At the same time, fixing the outer surface of the feed pipe to the inner wall of the gasifier shell can improve the stability of the feed pipe.

[0014] Furthermore, the slag discharge mechanism includes a slag discharge horizontal pipe fixedly connected to the inner wall of the gasifier lining, and the other end of the slag discharge horizontal pipe penetrates the outer shell of the gasifier and is fixedly connected to a third servo motor.

[0015] The above scheme facilitates subsequent slag removal work through the installed horizontal slag discharge pipe.

[0016] Furthermore, the output shaft end of the third servo motor is fixedly connected to a slag discharge auger, and the bottom of the slag discharge horizontal pipe is connected to a slag discharge vertical pipe.

[0017] With the above scheme, when the third servo motor is started, the slag discharge auger can be rotated, thereby discharging the residue inside the gasifier lining through the horizontal and vertical slag discharge pipes, which facilitates the reuse of the device.

[0018] Furthermore, four first support columns are fixedly connected to the bottom surface of the gasifier shell, and an anti-slip pad is fixedly connected to the bottom of each first support column.

[0019] The above scheme allows the device to be stably placed on the contact surface by setting the first support column.

[0020] Furthermore, the bottom surface of the pretreatment box is fixedly connected to two second support columns, and the bottom of each second support column is fixedly connected to an anti-slip pad, and the bottom of the first support column and the bottom of the second support column are on the same horizontal plane.

[0021] The above solution, with the addition of a second support column, can further improve the stability of the device and make it more practical.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This biomass power generation device, through the coordinated operation of the gasifier body and pretreatment mechanism, achieves structural optimization and energy closed-loop design, simplifying the device structure while improving efficiency. Biomass is crushed by two rotating crushing rollers, allowing it to fully undergo gasification within the gasifier lining. Simultaneously, a second servo motor and a feeding auger ensure smoother transport of the crushed biomass into the gasifier lining, reducing the risk of blockage. After gasification within the gasifier lining, residual heat is transferred to the pretreatment box via a spiral pipe and conveying pipe to dry the biomass inside, improving energy utilization. Finally, a slag removal mechanism removes residue from inside the gasifier lining. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 3 and Figure 5 The biomass power generation device in this embodiment includes a gasifier body 1, a pretreatment mechanism 2, and a slag discharge mechanism 3. The gasifier body 1 includes a gasifier shell 101 and a gasifier lining 102 fixedly connected to the inner wall of the gasifier shell 101. A spiral pipe 103 is sleeved on the outside of the gasifier lining 102. Both ends of the spiral pipe 103 are connected to conveying pipes 104. The spiral pipe 103 is located between the gasifier shell 101 and the gasifier lining 102. One end of each of the two conveying pipes 104 penetrates the gasifier shell 101 and extends to the outside of the gasifier shell 101, defining the spiral pipe 103. The location of the conveying pipe 104 allows for the recovery of waste heat generated by the gasification reaction in the gasifier lining 102, making it more practical. The top of the gasifier lining 102 is equipped with a gasifying agent inlet pipe 105 and a gas outlet pipe 106. The tops of both the gasifying agent inlet pipe 105 and the gas outlet pipe 106 penetrate the gasifier shell 101 and extend to the top of the gasifier shell 101. The gasifying agent inlet pipe 105 allows the gasifying agent to be added into the gasifier lining 102 to promote the gasification reaction, while the gas outlet pipe 106 allows the combustible gas generated inside the gasifier lining 102 to be discharged.

[0033] Please see Figure 2 , Figure 3 and Figure 4The pretreatment mechanism 2 includes a pretreatment box 201. A feeding port 205 is installed on the top of the pretreatment box 201, allowing biomass materials to be easily fed into the pretreatment box 201 for pretreatment. One end of each of the two conveying pipes 104 is connected to the interior of the pretreatment box 201. Waste heat recovered from the spiral pipe 103 and the conveying pipes 104 can be transferred to the pretreatment box 201, thus drying the biomass inside and improving energy utilization. Two crushing rollers 202 are rotatably mounted on the top of the pretreatment box 201. A planar gear 203 is fixedly connected to the shaft end of each crushing roller 202, and the two planar gears 203 mesh. A first servo motor 204 is fixedly connected to the outer surface of the pretreatment box 201. The output shaft end of the first servo motor 204 is fixedly connected to one end of the corresponding crushing roller 202. When the first servo motor 204 starts, the two crushing rollers can be driven by the two planar gears 203. The rollers 202 rotate simultaneously, and the rotation of the two crushing rollers 202 can crush the biomass conveyed by the feed port 205, so that the biomass can undergo a more complete gasification reaction in the gasifier lining 102. One end of the pretreatment box 201 is connected to the feed pipe 206. The output end of the feed pipe 206 is fixedly connected to the inner wall of the gasifier lining 102, and the outer surface of the feed pipe 206 is fixedly connected to the inner wall of the gasifier shell 101. The inner wall of 101 can improve the stability of the feed pipe 206. A second servo motor 207 is fixedly connected to one side of the feed pipe 206. A feeding auger 208 is fixedly connected to the output shaft end of the second servo motor 207. When the second servo motor 207 is started, it can drive the feeding auger 208 to rotate. Through the rotation of the feeding auger 208, the crushed biomass can be smoothly transported through the feed pipe 206 to the gasifier lining 102 for gasification reaction, reducing the risk of blockage.

[0034] Please see Figure 2 , Figure 3 and Figure 4The slag removal mechanism 3 includes a slag removal horizontal pipe 301 fixedly connected to the inner wall of the gasifier lining 102. The other end of the slag removal horizontal pipe 301 penetrates the gasifier outer shell 101 and is fixedly connected to a third servo motor 303. The slag removal horizontal pipe 301 facilitates subsequent slag removal. A slag removal auger 304 is fixedly connected to the output shaft of the third servo motor 303. The bottom of the slag removal horizontal pipe 301 is connected to a slag removal vertical pipe 302. When the third servo motor 303 is started, the slag removal auger 304 can rotate, thereby allowing the residue inside the gasifier lining 102 to be removed through the slag removal horizontal pipe 301 and the slag removal vertical pipe 302. The slag is discharged through the vertical pipe 302, facilitating the reuse of the device. Four first support columns 4 are fixedly connected to the bottom surface of the gasifier shell 101, and each first support column 4 has an anti-slip pad fixedly connected to its bottom. The first support columns 4 allow the device to be placed stably on the contact surface. Two second support columns 5 are fixedly connected to the bottom surface of the pretreatment box 201, and each second support column 5 has an anti-slip pad fixedly connected to its bottom. The bottoms of the first support columns 4 and the bottoms of the second support columns 5 are on the same horizontal plane. The second support columns 5 further improve the stability of the device and make it more practical.

[0035] In this embodiment, the biomass power generation device, through the cooperation of the gasifier body 1 and the pretreatment mechanism 2, can achieve structural optimization and energy closed-loop design, simplifying the device structure while improving efficiency. Biomass can be crushed by two rotating crushing rollers 202, allowing it to fully undergo gasification reaction in the gasifier lining 102. At the same time, the second servo motor 207 and the feeding auger 208 can more smoothly transport the crushed biomass into the gasifier lining 102, reducing the risk of blockage. After the gasification reaction in the gasifier lining 102, the waste heat can be transferred to the pretreatment box 201 through the spiral pipe 103 and the conveying pipe 104 to dry the biomass inside the pretreatment box 201, improving energy utilization. Finally, the slag discharge mechanism 3 can discharge the residue inside the gasifier lining 102.

[0036] The working principle of the above embodiment is as follows: Biomass is fed into the pretreatment box 201 through the feeding port 205 for pretreatment. Then, the first servo motor 204 is started, and the two planar gears 203 can make the two crushing rollers 202 rotate simultaneously. The two rotating crushing rollers 202 can crush the biomass. The crushed biomass will fall to the bottom of the pretreatment box 201. Then, the second servo motor 207 is started. When the second servo motor 207 is started, it can drive the feeding auger 208 to rotate. The rotation of the feeding auger 208 can transport the crushed biomass through the feed pipe 206 into the gasifier lining 102, and simultaneously through the gasifying agent inlet pipe 105. A gasifying agent is added to the inside of the gasifier lining 102, so that the biomass can undergo a gasification reaction in the gasifier lining 102 and produce combustible gas. The combustible gas will be output through the gas outlet pipe 106. The spiral pipe 103 can recover the waste heat generated in the gasification reaction process and transport the waste heat to the pretreatment box 201 through the conveying pipe 104. This can dry the crushed biomass inside the pretreatment box 201, improving the utilization rate of resources. Finally, the third servo motor 303 is started to rotate the slag discharge auger 304. The rotation of the slag discharge auger 304 can discharge the residue after reaction inside the gasifier lining 102 through the slag discharge horizontal pipe 301 and the slag discharge vertical pipe 302.
