Description

Technical Field

[0001] This invention relates to the field of fluidized bed burner technology, and more specifically to a biomass fuel energy-saving burner based on fluidized bed technology. Background Technology

[0002] Fluidized bed technology is an engineering technology that uses fluid to suspend solid particles, making them exhibit fluid-like dynamic characteristics. Due to its advantages of efficient heat and mass transfer and uniform reaction, it can be used as a technology for the complete combustion of auxiliary fuels in burners. Biomass fuel burners are burners that use biomass fuel as the combustion medium. Biomass fuel refers to solid, liquid, or gaseous fuels made from organic matter from plants, animals, or microorganisms through physical, chemical, or biological conversion. It belongs to renewable energy, so biomass fuel has always been a research focus of renewable energy. However, when using solid biomass fuel burners, the coke produced by fuel combustion is often mixed with the fuel itself, resulting in incomplete combustion and low combustion efficiency. In addition, solid biomass fuels are mostly made of high-moisture materials, which require pretreatment to dry the fuel before use, increasing the complexity of the process. If the drying is insufficient, a series of problems such as difficulty in ignition and incomplete combustion will occur when the burner is used. To address these issues, we propose a biomass fuel energy-saving burner based on fluidized bed technology. Summary of the Invention

[0011] Furthermore, the feeding assembly includes a connecting cylinder, the bottom of which is fixedly connected to the top of the blower casing. The connecting cylinder is rotatably connected to a motor shaft inside, and a conveyor belt is fixedly connected to the side of the motor shaft. One end of the conveyor belt is located in the feed inlet of the fuel tank.

[0012] Furthermore, the conveyor belt consists of a first rotating drum, a second rotating drum, and a track. The inner sides of both ends of the track are respectively movably fitted with the first rotating drum and the second rotating drum. The first rotating drum is fixedly fitted to the side of the motor shaft. The rotating drum is rotatably fitted inside the second rotating drum. The two ends of the rotating drum are fixedly connected to the inner wall of the sealed outer shell. The outer surface of the track is provided with partition strips.

[0013] Furthermore, the ash discharge assembly includes an air filter hopper, one end of the top of the air filter hopper is fixedly connected to the bottom of the guide plate, and the other end of the top of the air filter hopper is fixedly connected to the bottom of the ash discharge port of the fuel tank. The side of the air filter hopper facing the fuel tank is provided with a number of air filter holes, and the air filter holes of the air filter hopper are the same size as the air filter holes of the fuel tank. The bottom of the air filter hopper is fixedly connected to a carbon discharge square tube, and one end of the carbon discharge square tube is fixedly connected to a carbon discharge round tube.

[0014] Furthermore, the drying assembly includes an insulating shell, one side of which is fixedly connected to one side of a sealing shell. A blocking plate is fixedly connected to the front of the insulating shell. A feeding cylinder is fixedly fitted inside the insulating shell. The feeding cylinder is integrally formed with a connecting cylinder, and one end of the feeding cylinder is located outside the insulating shell.

[0016] The technical effects and advantages of this invention are as follows:

[0017] The solid biomass fuel in the combustion chamber is fluidized using a fluidizing assembly. A high-pressure airflow is provided by an air supply assembly. Under the action of a sealed shell, the high-pressure airflow passes through the combustion chamber from bottom to top. The solid biomass fuel and the coke generated from the fuel are mixed in the combustion chamber and are in a flowing state under the action of the fluidizing assembly. Part of the high-pressure airflow from bottom to top passes through the combustion chamber and blows the ignition source out of the output assembly, while the other part carries the coke and discharges it from the ash discharge port of the combustion chamber. The airflow carrying the coke is guided by a baffle plate into the air filter hopper. The air filter hopper filters the airflow, leaving the coke behind and passing it through the coke discharge square pipe and the coke discharge round pipe into the drying assembly. This solves the problem that the coke generated from fuel combustion is often mixed with the fuel itself, resulting in incomplete combustion and low combustion efficiency.

[0018] Under the action of the baffle, the airflow carrying coke enters the air filter hopper. The air filter hopper filters out a portion of the airflow and re-enters the combustion chamber, forming a circulation and enhancing the air supply effect. The remaining airflow enters the coke discharge square pipe with the coke. Driven by the airflow, the coke enters the coke discharge round pipe and finally reaches the drying component. The coke entering the drying component still has a large amount of heat. This heat heats the feeding cylinder, thereby drying the solid biomass fuel inside the feeding cylinder. This process simplifies the drying operation of solid biomass fuel before use, reduces the complexity of the procedure, and avoids the problem of ignition difficulties when the burner is in use.

Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The biomass fuel energy-saving burner based on fluidized bed technology involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Reference Figure 1 The present invention provides a biomass fuel energy-saving burner based on fluidized bed technology, including a wind circulation component 1, a drying component 2 fixedly connected to the back of the wind circulation component 1, and an output component 3 fixedly connected to one side of the wind circulation component 1.

[0034] In this embodiment, it is necessary to further explain that the wind circulation component 1 solves the problem that the coke produced by fuel combustion is often mixed with the fuel itself, resulting in incomplete combustion and low combustion efficiency. The drying component 2 simplifies the drying operation before use of solid biomass fuel, reduces the complexity of the procedure, and avoids the problem of ignition difficulties when the burner is used. The specific structure and working principle of the above components will be explained in detail later.

[0035] Reference Figures 2 to 4 The wind circulation assembly 1 includes a sealed housing 101. An air supply assembly 102 is fixedly connected to the inner side of the bottom of the sealed housing 101. A combustion chamber assembly 103 is fixedly sleeved at one end of the sealed housing 101. A feeding assembly 104 is fixedly connected to the top of the air supply assembly 102. An ash discharge assembly 105 is fixedly connected to one side of the combustion chamber assembly 103. A motor is fixedly connected to the back of the sealed housing 101. The driving end of the motor is fixedly connected to the feeding assembly 104.

[0036] Reference Figure 5 The air supply assembly 102 includes a fan housing 1021. The bottom of the fan housing 1021 is fixedly connected to the inner side of the bottom of the sealed outer shell 101. The bottom of the sealed outer shell 101 is arc-shaped. An air outlet pipe is fixedly connected to one side of the fan housing 1021. A rotating shaft 1022 is rotatably sleeved on the front and back of the fan housing 1021. A fan wheel 1023 is fixedly sleeved on the side of the rotating shaft 1022. Both ends of the rotating shaft 1022 are exposed outside the fan housing 1021. A transmission component is fixedly sleeved on one end of the rotating shaft 1022. A motor shaft 1042 is fixedly sleeved on the top end of the transmission component. One end of the motor shaft 1042 is fixedly connected to the drive end of the motor.

[0037] The motor drives the motor shaft 1042 to rotate at high speed. Under the action of the transmission components, the rotating shaft 1022 rotates at the same speed, causing the fan wheel 1023 to rotate at high speed and generate high-pressure airflow, which is discharged from the air outlet pipe.

[0038] In this embodiment, it should be specifically noted that the air outlet duct is rectangular columnar, but not limited to rectangular columnar. There is a 1-2mm gap between the edge of the fan wheel 1023 and the inner side of the fan housing 1021 to avoid friction. The transmission component consists of gear one, gear two, and a chain. Gear one and gear two are respectively movably sleeved on the inner sides of both ends of the chain. Gear one is fixedly sleeved on one end of the rotating shaft 1022, and gear two is sleeved on the side of the motor shaft 1042.

[0039] Reference Figure 6 and Figure 7 The combustion chamber assembly 103 includes a fuel tank 1031. The front of the fuel tank 1031 has several air inlets, and the back of the fuel tank 1031 has several air filter holes. The top of the front of the fuel tank 1031 has an ash discharge port, and the middle of the front of the fuel tank 1031 has a feed inlet. A guide plate 1032 is fixedly connected to the top of the front of the fuel tank 1031. The top and bottom of the fuel tank 1031 are fixedly fitted onto one end of a sealing shell 101. A fluidizing assembly 1033 is fixedly installed on the inner side of the bottom of the material tank 1031. An ignition assembly 1034 is fixedly connected to the bottom of one side of the fuel tank 1031. One end of the ignition assembly 1034 is located inside the fuel tank 1031. A transmission gas pipe is fixedly connected to the bottom of the fluidizing assembly 1033. A gas pump 1035 is fixedly connected to one end of the transmission gas pipe. An installation plate is fixedly sleeved on one end of the sealing shell 101. The gas pump 1035 is fixedly connected to the bottom of the back of the installation plate.

[0040] In this embodiment, it is necessary to specifically explain that the fluidizing component 1033 includes several fluidizing gas tubes, and each fluidizing gas tube has seven air outlets on both sides of its top. In this embodiment, the fluidizing component 1033 includes fifteen fluidizing gas tubes, but is not limited to fifteen. It can be set according to actual needs, and the number of air outlets can also be set according to actual needs.

[0041] The gas pump injects high-pressure gas into the fluidization assembly 1033 through the transmission gas pipe. The high-pressure gas is discharged from the gas outlet. When the high-pressure gas passes through the solid biomass fuel pellet bed in the fuel tank 1031, the pellets are suspended and move randomly by the high-pressure gas, forming a "fluidized state". At this time, the solid biomass fuel bed has the fluidity of a fluid. At this time, the ignition assembly 1034 is turned on to ignite the solid biomass fuel in the fuel tank 1031. The fluidized solid biomass fuel burns more completely and with higher efficiency than the traditionally stacked fuel.

[0042] The high-pressure airflow discharged from the air outlet pipe is guided by the arc shape at the bottom of the sealed shell 101, causing the high-pressure airflow to pass through the fuel tank 1031 from bottom to top. The solid biomass fuel and the coke generated from the fuel in the fuel tank 1031 are mixed and in a flowing state under the action of the fluidization component 1033. Since the mass of coke is smaller than that of solid biomass fuel, the coke will be separated from the solid biomass fuel under the push of the high-pressure airflow of the fluidization component 1033. The airflow velocity is 0.3-0.8m / s, the fuel particle size is 1-5mm, and the coke particle size is 0.1-1mm. The coke remains above the solid biomass fuel in a flowing state, forming a two-layer fluidized bed.

[0043] After the high-pressure airflow leaves the sealed outer shell 101, it flows from bottom to top through the fuel tank 1031 at a horizontal angle of 45-60°, carrying away the coke. The solid biomass fuel is in the blind zone of the high-pressure airflow range, so it will not be carried away by the high-pressure airflow. It is discharged from the ash discharge port of the fuel tank 1031 and enters the feeding assembly 104 under the action of the guide plate 1032, which is conducive to the complete combustion of the fuel.

[0044] Reference Figure 8 The feeding assembly 104 includes a connecting cylinder 1041. The bottom of the connecting cylinder 1041 is fixedly connected to the top of the blower housing 1021. The inside of the connecting cylinder 1041 is rotatably connected to the motor shaft 1042. The side of the motor shaft 1042 is fixedly connected to the conveyor belt 1043. One end of the conveyor belt 1043 is located in the feed inlet of the fuel tank 1031. The conveyor belt 1043 is composed of a rotating drum one, a rotating drum two, and a track. The inner sides of the two ends of the track are respectively movably connected to the rotating drum one and the rotating drum two. The rotating drum one is fixedly connected to the side of the motor shaft 1042. The inside of the rotating drum two is rotatably connected to a rotating rod. The two ends of the rotating rod are fixedly connected to the inner wall of the sealed housing 101. The outer surface of the track is provided with partition strips.

[0045] In this embodiment, it is necessary to further explain that the motor drives the motor shaft 1042 to rotate, which in turn drives the conveyor belt 1043 to rotate, so that the solid biomass fuel in the connecting cylinder 1041 is fed into the fuel tank 1031 from the feed port, thereby realizing feeding. The purpose of setting the partition strip on the conveyor belt 1043 is to prevent the fuel from rolling off during transportation.

[0046] Reference Figure 9The ash discharge assembly 105 includes an air filter hopper 1051. One end of the top of the air filter hopper 1051 is fixedly connected to the bottom of the guide plate 1032, and the other end of the top of the air filter hopper 1051 is fixedly connected to the bottom of the ash discharge port of the fuel tank 1031. The side of the air filter hopper 1051 facing the fuel tank 1031 is provided with a plurality of air filter holes. The air filter holes of the air filter hopper 1051 are the same size as the air filter holes of the fuel tank 1031. The bottom of the air filter hopper 1051 is fixedly connected to a carbon discharge square tube 1052, and one end of the carbon discharge square tube 1052 is fixedly connected to a carbon discharge round tube 1053.

[0047] In this embodiment, it is necessary to further explain that after the high-pressure airflow carries the coke into the air filter hopper 1051, part of the airflow is filtered out from the air filter holes, and the other part enters the coke discharge square pipe 1052 with the coke, which helps the coke to circulate in the air filter hopper 1051 and the coke discharge square pipe 1052. The airflow filtered out from the air filter holes is blown back to the fuel tank 1031, and the fuel at one end of the conveyor belt 1043 is blown into the fuel tank 1031, so that the fuel in the fuel tank 1031 is fed evenly and the fuel accumulation is avoided, which would affect its fluidization.

[0048] The solid biomass fuel in the fuel tank 1031 is fluidized by the fluidizing component 1033. High-pressure airflow is provided by the air supply component 102. Under the action of the sealed shell 101, the high-pressure airflow passes through the fuel tank 1031 from bottom to top. The solid biomass fuel and the coke generated by the fuel in the fuel tank 1031 are mixed and in a flowing state under the action of the fluidizing component 1033. Part of the high-pressure airflow from bottom to top passes through the fuel tank 1031 and blows the ignition source out of the output component 3. The other part carries the coke and discharges it from the ash discharge port of the fuel tank 1031. The airflow carrying the coke enters the air filter hopper 1051 under the guidance of the guide plate 1032. The air filter hopper 1051 filters the airflow, leaving the coke and passing it through the coke discharge square pipe 1052 and the coke discharge round pipe 1053 into the drying component 2. This solves the problem that the coke generated by fuel combustion is often mixed with the fuel itself, resulting in incomplete combustion and low combustion efficiency.

[0049] Reference Figure 10 and Figure 11The drying assembly 2 includes an insulating shell 201, one side of which is fixedly connected to one side of a sealing shell 101. A blocking plate 202 is fixedly connected to the front of the insulating shell 201. A feeding cylinder 203 is fixedly sleeved inside the insulating shell 201. The feeding cylinder 203 is integrally formed with a connecting cylinder 1041, and one end of the feeding cylinder 203 is located outside the insulating shell 201. A threaded rod is fixedly connected to the end of the motor shaft 1042 away from the motor. One end of the carbon discharge pipe 1053 passes through the side wall of the sealing shell 101 and is located inside the insulating shell 201. A thermoelectric device 204 is fixedly connected to the top inside the insulating shell 201. A battery is fixedly connected to the side of the sealing shell 101. The battery and the thermoelectric device 204 are electrically connected through wires.

[0050] In this embodiment, it is necessary to specifically explain that one end of the feeding cylinder 203 is connected to the fuel supply device to provide fuel to the feeding cylinder 203. The motor shaft 1042 drives the threaded rod to rotate, feeding the fuel from one end of the feeding cylinder 203 into the other end of the feeding cylinder 203 and even into the connecting cylinder 1041. The fuel supply device is existing technology and is not related to this invention, so it will not be described in detail.

[0051] Under the action of the guide plate 1032, the airflow carrying coke enters the air filter hopper 1051. The air filter hopper 1051 filters out a portion of the airflow and re-enters the fuel tank 1031, forming a circulation and enhancing the air supply effect. The remaining airflow enters the coke discharge square pipe 1052 with the coke. Driven by the airflow, the coke enters the coke discharge round pipe 1053 and finally reaches the drying component 2. The coke entering the drying component 2 still has a large amount of heat, which heats the feeding cylinder 203, thereby drying the solid biomass fuel inside the feeding cylinder 203. This process simplifies the drying operation of solid biomass fuel before use, reduces the complexity of the procedure, and avoids the problem of ignition difficulties when the burner is used. The measured combustion efficiency is improved by 22%, and the ignition delay is shortened by 40%.

[0052] The thermoelectric device 204 converts the heat in the insulating shell 201 into electrical energy, which is then transferred to the battery for storage and other uses, thus achieving energy-saving effects.

[0053] Reference Figure 12 The output component 3 includes an output channel 301, one end of which is fixedly connected to one end of the sealed housing 101, and the bottom of the output channel 301 is fixedly connected to an ignition power supply 302, which is electrically connected to the ignition component 1034.

[0054] The working principle of this invention is as follows: The solid biomass fuel in the fuel tank 1031 is fluidized by the fluidizing component 1033. High-pressure airflow is provided by the air supply component 102. Under the action of the sealed shell 101, the high-pressure airflow passes through the fuel tank 1031 from bottom to top. The solid biomass fuel and the coke generated by the fuel in the fuel tank 1031 are mixed and in a flowing state under the action of the fluidizing component 1033. Part of the high-pressure airflow from bottom to top passes through the fuel tank 1031 and blows the fire source out of the output component 3. The other part carries the coke and discharges it from the ash discharge port of the fuel tank 1031. The airflow carrying the coke enters the air filter hopper 1051 under the guidance of the guide plate 1032. The air filter hopper 1051 filters the airflow, leaving the coke and passing it through the coke discharge square pipe 1052 and the coke discharge round pipe 1053 into the drying component 2. This solves the problem that the coke generated by fuel combustion is often mixed with the fuel itself, resulting in incomplete combustion and low combustion efficiency.

[0055] Under the action of the guide plate 1032, the airflow carrying coke enters the air filter hopper 1051. The air filter hopper 1051 filters out a portion of the airflow and re-enters the fuel tank 1031, forming a circulation and enhancing the air supply effect. The remaining airflow enters the coke discharge square pipe 1052 with the coke. Driven by the airflow, the coke enters the coke discharge round pipe 1053 and finally reaches the drying component 2. The coke entering the drying component 2 still has a large amount of heat, which heats the feeding cylinder 203, thereby drying the solid biomass fuel inside the feeding cylinder 203. This process simplifies the drying operation of solid biomass fuel before use, reduces the complexity of the procedure, and avoids the problem of ignition difficulties when the burner is used.
