Description

Technical Field

[0001] This utility model relates to the field of biomass boiler technology, and in particular to an emission-reducing and environmentally friendly biomass boiler device. Background Technology

[0002] Biomass boilers use biomass materials such as crop straw, forest waste, and urban organic waste as fuel, which is fed into the combustion chamber through a feeding system. The fuel is preheated in the combustion chamber until it reaches the volatile matter release point, and then the igniter starts it to burn, releasing a large amount of heat energy.

[0003] During combustion, a high-efficiency fan introduces an appropriate amount of air to ensure complete combustion of the fuel. The high-temperature flue gas generated by combustion washes over the main heating surfaces of the boiler, and transfers heat energy to the water or other media inside the boiler through a heat exchanger, heating the water into hot water or converting it into steam, thereby realizing the conversion and utilization of heat energy.

[0004] For example, the existing Chinese patent with publication number CN213514407U discloses a horizontal biomass boiler device, which uses a first motor to drive a first transmission belt, a first connecting disc and a screw rod to rotate, so as to send fuel into the furnace for combustion.

[0005] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: After the fuel leaves the screw, it will no longer move due to the lack of conveying power. Even if some fuel is squeezed and pushed later, most of the fuel will still accumulate on one side of the furnace, resulting in incomplete combustion and the generation of toxic black smoke particles, nitrogen oxides and other pollutants, which are harmful to health. In addition, the fuel does not react completely, resulting in a lot of heat waste. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of incomplete combustion due to fuel accumulation, which leads to a large amount of pollutants and heat waste. To this end, we propose an emission reduction and environmentally friendly biomass boiler equipment.

[0007] To achieve the above objectives, this application adopts the following technical solution: an emission reduction and environmental protection biomass boiler equipment, including a boiler body, a feed plate is hinged on one side of the boiler body, a placement mechanism is provided on the inner side of the boiler body, and a furnace is provided inside the boiler body.

[0008] The placement mechanism includes a placement plate that is slidably connected to and tightly fitted against the inner wall of the boiler body. Connecting plates are fixedly installed on both sides of the placement plate, and these plates are slidably connected to the boiler body. A spring is fixedly installed at the lower end of each connecting plate, and a second connecting plate is fixedly installed at the lower end of each spring. The second connecting plate is bolted to the outer wall of the boiler body. Electromagnets are fixedly installed at the adjacent ends of both connecting plates, with the electromagnets sleeved on the outside of the springs. First, the feed plate is opened, and fuel is inserted into the boiler body for combustion. During subsequent combustion, the electromagnets are periodically energized. When energized, the two electromagnets attract each other magnetically, forcing the first connecting plate to gradually lower the placement plate. The spring is compressed, and then the electromagnet is de-energized. Relying on the spring's restoring potential energy, the connecting plate is pushed to move the placement plate upwards rapidly until the connecting plate collides and contacts the boiler body. Due to the sudden stop of the placement plate's ascent, the fuel continues to move upwards due to inertia, moving away from the surface of the placement plate. This creates an effect of throwing the fuel upwards, achieving a certain mixing effect. At the same time, when the fuel falls back onto the surface of the placement plate, it also has a leveling effect, preventing the fuel from being fixed in position or piling up, making combustion more complete, reducing the production of pollutants such as toxic black smoke particles and nitrogen oxides, achieving emission reduction. Furthermore, because the fuel is fully utilized, the recovered heat energy can be fully utilized.

[0009] Preferably, baffles are fixedly installed at both ends of the connecting plate one. The baffles slide and connect with the inner wall of the boiler body to prevent combustion impurities inside the boiler body from escaping during the movement of the connecting plate one, thus affecting the working environment.

[0010] Preferably, the placement plate has multiple through holes running through it. A discharge plate is hinged to the other side of the boiler body. Tracks are symmetrically installed on the inner wall of the boiler body. A threaded rod is rotatably installed on the inner wall of the boiler body. A collection plate is threaded on the outer side of the threaded rod. The collection plate is slidably connected to and tightly fitted with the inner wall of the boiler body and the track. After a period of use, a large amount of fuel waste that has been burned and fallen from the through holes will accumulate inside the boiler body. When cleaning is required, the personnel only need to open the discharge plate and rotate the threaded rod to drive the collection plate to move horizontally. As the collection plate moves horizontally, it will gradually collect the fuel waste and eventually push it to the discharge plate for discharge, which is convenient for subsequent centralized treatment.

[0011] Preferably, an exchange component is provided inside the boiler body. The exchange component includes a water storage tank. An inlet pipe is bolted to the upper end of the water storage tank, penetrating the boiler body and fixedly connected. An outlet pipe is bolted to one side of the water storage tank, penetrating the boiler body and fixedly connected. A space is reserved between the outer wall of the water storage tank and the inner wall of the boiler body. During fuel combustion, the inlet and outlet pipes are connected to external pipes, filling the water storage tank with water. This allows the heat in the flue gas to exchange with the water in the water storage tank, achieving energy reuse.

[0012] Preferably, an environmental protection mechanism is provided at the upper end of the boiler body. The environmental protection mechanism includes an outer shell fixedly connected to the boiler body. An air inlet pipe fixedly connected to the boiler body is installed at one end of the outer shell, and an exhaust pipe connected to the desulfurization equipment is installed at the other end of the outer shell. A filter plate and an activated carbon plate are slidably installed on the inner side of the outer shell. After heat exchange, the flue gas enters the outer shell from the air inlet pipe and is initially filtered by the filter plate and activated carbon plate. Then, it enters the dedicated desulfurization equipment from the exhaust pipe for further treatment, thereby achieving environmentally friendly emissions.

[0013] Preferably, combustion-supporting pipes are symmetrically installed on the outer wall of the boiler body. During the combustion process, outside air enters the interior of the boiler body through the combustion-supporting pipes, which plays a role in assisting combustion and ensuring the complete combustion of fuel.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the operator first opens the feed plate and inserts fuel into the boiler body for combustion. During the subsequent combustion process, the electromagnets are periodically energized. When energized, the two electromagnets attract each other magnetically, forcing the connecting plate to gradually lower the placement plate, compressing the spring. Then, the electromagnets are de-energized, and the spring's restoring potential energy pushes the connecting plate to rapidly rise until it collides and contacts the boiler body. Due to the sudden stop of the placement plate's rise, the fuel continues to move upward away from the surface of the placement plate due to inertia, thus creating an upward throwing effect on the fuel and achieving a certain mixing effect. At the same time, when the fuel falls back to the surface of the placement plate, it also has a leveling effect, preventing the fuel from being fixed in position or accumulating, making combustion more complete, reducing the production of pollutants such as toxic black smoke particles and nitrogen oxides, achieving emission reduction. Furthermore, because the fuel is fully utilized, the recovered heat energy can be fully utilized. Attached Figure Description

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figure 1-3 As shown, this utility model provides a technical solution: an emission reduction and environmental protection biomass boiler equipment, including a boiler body 1, a feed plate 11 is hinged on one side of the boiler body 1, a placement mechanism 4 is provided on the inner side of the boiler body 1, and a furnace 13 is provided inside the boiler body 1.

[0025] The placement mechanism 4 includes a placement plate 41 that is slidably connected to and tightly fitted to the inner wall of the boiler body 1. Connecting plates 43 are fixedly installed on both sides of the placement plate 41. The connecting plates 43 are slidably connected to the boiler body 1. A spring 44 is fixedly installed at the lower end of the connecting plate 43, and a connecting plate 45 is fixedly installed at the lower end of the spring 44. The connecting plate 45 is bolted to the outer wall of the boiler body 1. Electromagnets 46 are fixedly installed at the ends of the connecting plates 43 and 45 that are close to each other. The electromagnets 46 are sleeved on the outside of the spring 44. First, the operator opens the feed plate 11 and inserts fuel into the boiler body 1 for combustion. During subsequent combustion, the electromagnets 46 are periodically energized. After being energized, the two electromagnets 46 attract each other magnetically, forcing the connecting plates 43... The placement plate 41 gradually descends, compressing the spring 44. Then, the electromagnet 46 is de-energized. Relying on the restoring potential energy of the spring 44, the connecting plate 43 pushes the placement plate 41 to rise rapidly until the connecting plate 43 collides and abuts against the boiler body 1. Due to the sudden stop of the placement plate 41's ascent, the fuel continues to move upward away from the surface of the placement plate 41 due to inertia, thus creating an effect of throwing the fuel upward and playing a certain role in mixing. At the same time, when the fuel falls back to the surface of the placement plate 41, it also has a leveling effect, preventing the fuel from being fixed in position and accumulating, making combustion more complete, reducing the production of pollutants such as toxic black smoke particles and nitrogen oxides, achieving emission reduction effect. Moreover, due to the complete fuel supply, the recovered heat energy can be fully utilized.

[0026] Reference Figure 3 As shown in this embodiment: baffles 47 are fixedly installed at both ends of the connecting plate 43. The baffles 47 are slidably connected to the inner wall of the boiler body 1, which can prevent combustion impurities inside the boiler body 1 from escaping during the movement of the connecting plate 43 and affecting the working environment.

[0027] Reference Figure 3 , Figure 5 As shown in this embodiment: the interior of the placement plate 41 has multiple through holes 42. The other side of the boiler body 1 is hinged to a feeding plate 12. The inner wall of the boiler body 1 is symmetrically equipped with rails 15. The inner wall of the boiler body 1 is rotatably equipped with a threaded rod 16. The outer side of the threaded rod 16 is threaded with a collection plate 17. The collection plate 17 is slidably connected to the inner wall of the boiler body 1 and the rails 15 and fits tightly. After a period of use, a large amount of fuel waste that has been burned and fallen from the through holes 42 will accumulate inside the boiler body 1. When cleaning is required, the personnel only need to open the feeding plate 12 and rotate the threaded rod 16 to drive the collection plate 17 to move horizontally. As the collection plate 17 moves horizontally, it will gradually collect the fuel waste and eventually push it to the feeding plate 12 for discharge, which is convenient for subsequent centralized treatment.

[0028] Reference Figure 2As shown in this embodiment: an exchange component 2 is provided inside the boiler body 1. The exchange component 2 includes a water storage tank 21. An inlet pipe 22 is bolted to the upper end of the water storage tank 21, penetrating the boiler body 1 and fixedly connected. An outlet pipe 23 is bolted to one side of the water storage tank 21, penetrating the boiler body 1 and fixedly connected. A space is reserved between the outer wall of the water storage tank 21 and the inner wall of the boiler body 1. During the combustion of fuel, the inlet pipe 22 and the outlet pipe 23 are connected to the external pipe, so that the water storage tank 21 is filled with water, thereby exchanging heat between the flue gas and the water in the water storage tank 21 to achieve energy reuse.

[0029] Reference Figure 4 As shown in this embodiment: An environmental protection mechanism 3 is provided at the upper end of the boiler body 1. The environmental protection mechanism 3 includes an outer shell 31 fixedly connected to the boiler body 1. An air inlet pipe 34 fixedly connected to the boiler body 1 is installed at one end of the outer shell 31, and an exhaust pipe 35 connected to the desulfurization equipment is installed at the other end of the outer shell 31. A filter plate 33 and an activated carbon plate 32 are slidably installed on the inner side of the outer shell 31. After heat exchange, the flue gas enters the outer shell 31 from the air inlet pipe 34 and is initially filtered by the filter plate 33 and the activated carbon plate 32. Then, it enters the special desulfurization equipment from the exhaust pipe 35 for further treatment, thereby achieving environmentally friendly emissions.

[0030] Reference Figure 1-2 As shown in this embodiment, combustion-supporting pipes 14 are symmetrically installed on the outer wall of the boiler body 1. During the combustion process, outside air enters the interior of the boiler body 1 through the combustion-supporting pipes 14, which plays a role in combustion support and ensures the complete combustion of fuel.

[0031] Working principle: First, the operator opens the feed plate 11 and inserts fuel into the boiler body 1 for combustion. During the subsequent combustion process, the electromagnets 46 are energized periodically. When energized, the two electromagnets 46 attract each other magnetically, forcing the connecting plate 43 to gradually lower the placement plate 41, compressing the spring 44. Then, the electromagnets 46 are de-energized. Relying on the restoring potential energy of the spring 44, the connecting plate 43 is pushed to rapidly rise, until the connecting plate 43 collides and abuts against the boiler body 1. Due to the sudden stop of the placement plate 41 rising, the fuel continues to move upward away from the surface of the placement plate 41 due to inertia, thus creating an effect of throwing the fuel upward, which plays a certain role in mixing. At the same time, when the fuel falls back to the surface of the placement plate 41, it also has a leveling effect, preventing the fuel from being fixed in position and accumulating, making the combustion more complete, reducing the production of pollutants such as toxic black smoke particles and nitrogen oxides, achieving emission reduction effect. Moreover, because the fuel is fully utilized, the recovered heat energy can be fully utilized.
