Description

Technical Field

[0001] This invention relates to the field of biomass fuel production and processing technology, and in particular to a biomass fuel reactor. Background Technology

[0002] A biomass fuel reactor is a core piece of equipment that converts biomass fuels such as straw, wood chips, and organic waste into thermal energy through complete combustion in an aerobic environment. It is mainly used for heating, industrial heating, or driving generators to generate electricity and is one of the most technologically mature and widely used pieces of equipment in the utilization of biomass energy.

[0003] When reacting biomass fuels, the raw materials need to undergo drying and crushing pretreatment to adapt to combustion conditions. Common types include fixed-bed and fluidized-bed reactors. Precise control of temperature and pressure is required during operation to address reaction instability caused by raw material fluctuations and tar coking issues. Simultaneously, environmental protection equipment is needed to treat pollutants. It can reduce fossil fuel consumption, contribute to carbon reduction, and is widely used in heating, industrial heating, and power generation. With high technological maturity, it is an important piece of equipment for promoting energy structure transformation.

[0004] A biomass fuel reactor disclosed in Chinese patent CN218064949U uses a conduit to fix the liquid storage tank in the material additive to the pump body. The pump body pressurizes the liquid fuel in the storage tank and quickly introduces it into the rotating shaft through the first and second rotating pipes. The arc groove at the connection between the rotating shaft and the rotating blade introduces the liquid fuel into the rotating blade. The drive motor drives the rotating shaft to rotate, and at the same time, the rotating blade rotates the internal liquid fuel and causes centrifugal motion, so that it can fully contact the burner and be ignited, avoiding incomplete combustion of fuel and affecting combustion efficiency.

[0005] However, compared with existing technologies and comparative solutions, it can be seen that this biomass fuel reactor still has the following problems in actual use: When reacting with liquid fuel, if the liquid fuel contains solid impurities such as straw fragments and fibers, it can easily clog the atomizing holes, resulting in uneven fuel spraying. This can lead to incomplete combustion, as the fuel and the oxidant sprayed from the burner do not mix fully. Incomplete combustion will produce impurities such as carbon residue and tar. This mixture of impurities will not only adhere to the inner wall of the reactor but also to the surface of the rotating blades, making cleaning inconvenient and time-consuming, thus affecting overall work efficiency. Summary of the Invention

[0006] The purpose of this invention is to at least address one of the aforementioned technical deficiencies.

[0007] The purpose of this invention is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a biomass fuel reactor.

[0008] The objective of this invention is achieved through the following technical solution: a biomass fuel reactor, comprising a shell, a driving component fixedly installed at the bottom of the shell, a reaction mechanism being drivenly connected to the output end of the driving component, and the reaction mechanism being rotatably connected inside the shell; The reaction mechanism includes an intermediate tube, on which a spraying component and a cleaning component are installed; A second gear is fixedly connected to one end of the intermediate tube. A feed pipe is provided on the side of the second gear away from the intermediate tube. A rotary joint is provided between the feed pipe and the second gear. A one-way valve is provided on the feed pipe. The spraying assembly includes a spray pipe and a spray head, with the spray head installed on the spray pipe; One end of the spray pipe is fixedly connected to a first connector, the spray pipe has a connection port, and the inner wall of the spray pipe has a first spiral groove. One end of the spray head is fixedly connected to a second connector, the inside of the spray head is provided with a second spiral groove, and the spray head is provided with spiral spray holes.

[0009] Preferably, the top of the housing is provided with a top cover, a drain pipe is fixedly connected to one side of the bottom of the housing, an air inlet pipe and a pressure relief valve are provided on the housing, a burner is provided between the air inlet pipe and the housing, and a support leg is fixedly connected to the bottom of the housing.

[0010] Preferably, the output end of the drive component is fixedly connected to a first gear.

[0011] Preferably, the cleaning component includes a connecting seat, which is fixedly connected to the intermediate tube by bolts. A sleeve is fixedly connected to one side of the connecting seat, and a slide rod is slidably connected inside the sleeve. An elastic element is provided at one end of the slide rod, which is located inside the sleeve. The end of the elastic element away from the slide rod is connected to the connecting seat, and a scraper is fixedly connected to the end of the slide rod away from the elastic element.

[0012] Preferably, the second gear meshes with the first gear.

[0013] Preferably, the spray pipe is fixedly connected to the intermediate pipe via a first connector.

[0014] Preferably, the second connector is adapted to the connector port, and the spray head is fixedly connected to the spray pipe through the second connector.

[0015] Compared with existing technologies, it has the following advantages: In this biomass fuel reactor, when liquid fuel passes through the spray pipe and spray head, it generates turbulence along the first and second spiral channels, guiding the solid particles in the liquid fuel to disperse evenly. This prevents blockage of the spray pipe or spray head due to local accumulation of solid particles in the liquid fuel, ensuring uniform mixing of fuel and oxygen and avoiding incomplete combustion. If impurities adhere to the spray pipe, it can be easily removed from the middle pipe for cleaning, reducing the time required for cleaning and thus improving overall work efficiency.

[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0023] The work process is as follows: S1. When in use, start the drive unit 2. The drive unit 2 drives the second gear 311 to rotate through the first gear 201.
