Description

Technical Field

[0001] This utility model relates to the field of biomass fuel drying technology, and more specifically to a self-drying and storage biomass fuel bin. Background Technology

[0002] Biomass fuel, as a renewable resource, has broad application prospects in the energy sector. However, biomass fuel typically contains high moisture content after collection, often ranging from 30% to 70%. To meet the moisture content requirements of equipment such as gasifiers (usually below 30%), biomass fuel needs to be dried before use.

[0003] Currently, the main methods for drying biomass fuel are as follows:

[0004] Off-site drying: Biomass fuel is transported to a designated drying area outside the plant for air drying or dried using drying equipment. This method has several problems:

[0005] (1) Large space required: Drying requires a large area, which increases the use of land resources.

[0006] (2) Greatly affected by weather: Under adverse weather conditions such as rain, snow, and strong winds, the drying effect is poor and may even cause the fuel to become damp, increasing drying time and cost.

[0007] (4) High transportation costs: The dried biomass fuel needs to be transported back to the plant for use, which increases transportation and time costs.

[0008] Conventional storage in factory silos: Some companies directly store biomass fuel in conventional steel-structured silos within the factory. However, these silos cannot meet the requirements for drying and sun-drying, making it difficult to reduce the moisture content of the biomass fuel. Furthermore, the fuel is prone to moisture absorption during storage, affecting its quality.

[0009] Therefore, developing a self-drying and storage biomass fuel bin that integrates drying and storage, which can reduce the transshipment of biomass materials, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] In view of this, the present invention provides a self-drying and storage biomass fuel bin that can reduce the handling of biomass materials and integrate drying and storage.

[0011] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] A self-drying and biomass fuel storage bin includes:

[0013] The storage body has a door on its side wall;

[0014] A drying coil, in which a heat transfer medium is circulated, and the drying coil is laid on the bottom surface of the chamber.

[0015] A heat insulation layer is laid on the bottom and sides of the drying coil;

[0016] A drying hood is placed inside the silo and covers the outside of the biomass fuel.

[0017] The beneficial effects of adopting the above technical solution are that the combination of the silo body, drying coil, insulation layer and drying hood realizes the function of drying and storing biomass fuel in the same silo body, reduces the handling of biomass fuel, improves work efficiency and reduces costs.

[0018] Preferably, a solar collector is installed on the roof of the silo, and the medium of the solar collector is connected to the drying coil through a pipeline. Utilizing solar energy to provide heat to the drying coil achieves the use of renewable energy, reduces drying costs, and decreases reliance on traditional energy sources, thus achieving environmental protection and energy-saving effects.

[0019] Preferably, a connector is provided at the top of the storage tank, and the connector is connected to the solar collector. Providing a connector to the solar collector ensures that the solar collector can be securely installed at the top of the storage tank, guaranteeing the installation stability of the solar collector, avoiding safety hazards caused by insecure installation, and also facilitating the maintenance and replacement of the solar collector.

[0020] Preferably, the solar collector is connected to a crossbeam, and the crossbeam is connected to the connector.

[0021] Preferably, the ground of the silo is paved with a concrete layer, and the drying coil is embedded inside the concrete layer. The concrete layer, filled with steel fiber reinforced concrete and steel mesh, improves the load-bearing capacity and structural strength of the silo ground, better supporting the weight of the biomass fuel. It also facilitates the fixation and protection of the drying coil, extending its service life.

[0022] Preferably, a partition joint is provided around the drying area on the bottom surface of the silo. This partition joint separates the drying area from other areas of the ground, preventing heat and moisture generated during the drying process from spreading to other areas and improving drying efficiency.

[0023] Preferably, the top of the drying hood is equipped with a rope for raising and lowering the drying hood. The rope at the top of the drying hood drives its raising and lowering, and the lifting device enables the drying hood to move up and down. When drying is required, the drying hood can cover the biomass fuel for drying; when drying is not required, the drying hood can be raised to the top of the storage chamber, avoiding any impact on the storage of biomass fuel. This improves the flexibility and practicality of the device, allowing for convenient switching between drying and storage modes according to actual needs.

[0024] Preferably, a ventilation device is provided on the side wall of the drying hood. The ventilation device on the side wall of the drying hood promotes air circulation within the drying hood, ensures uniform humidity distribution, and removes evaporated moisture from the drying hood, thereby accelerating the drying speed of biomass fuel, improving drying efficiency, and also ensuring air quality and temperature stability within the drying hood, which is beneficial for the uniform drying of biomass fuel.

[0025] Preferably, the side walls of the storage silo are equipped with dustproof mesh windows. These dustproof mesh windows prevent dust from entering the silo, keeping it clean and avoiding dust contamination of the biomass fuel. They also facilitate ventilation, maintaining a good environment within the silo and promoting the storage of biomass fuel.

[0026] Preferably, a feeding port is provided on the side wall of the silo.

[0027] As can be seen from the above technical solution, compared with the prior art, this utility model discloses a self-drying and biomass fuel storage bin, the beneficial effects of which are:

[0028] (1) The self-drying and storage biomass fuel bin of this utility model integrates drying and storage functions, reducing the handling of biomass fuel and lowering transportation and time costs.

[0029] (2) The use of solar collectors to provide heat energy for the drying process realizes the utilization of renewable energy, reduces drying costs, and has the effects of environmental protection and energy saving. At the same time, by optimizing the silo structure, setting up insulation layers, concrete layers, partitions, ropes, ventilation devices, dustproof nets and feeding ports, the structural stability, load-bearing capacity, drying efficiency, flexibility and practicality of the device are improved, ensuring uniform drying and good storage of biomass fuel, avoiding biomass fuel from getting damp and contaminated, improving the quality and safety of biomass fuel, and better meeting the requirements of gasifiers and other equipment for fuel moisture content.

[0030] (3) In practical applications, the device can be constructed using the existing biomass silo site within the plant, without needing to occupy the site outside the plant. Attached Figure Description

[0042] Drying coil 2, a heat transfer medium is introduced into drying coil 2, and drying coil 2 is laid on the bottom surface of the chamber 1;

[0043] Insulation layer 3 is laid on the bottom and sides of the drying coil 2;

[0044] The drying hood 4 is placed inside the silo 1 and covers the outside of the biomass fuel 5. The insulation layer 3 isolates the ground moisture and also prevents the heat from the drying coil 2 from being transferred downwards.

[0045] To further optimize the above technical solution, a solar collector 6 is installed on the roof of the outer casing 1. The medium of the solar collector 6 is connected to the drying coil 62 through pipelines. The solar collector 6 is an existing device. When the moisture content of the biomass fuel does not meet the combustion requirements, the solar collector 6 absorbs solar radiation during the day when sunlight shines directly on it, and then converts the light energy into heat energy to heat the internal medium. The heated medium enters the drying coil 2 through pipelines, and the heat dissipation from the drying coil 2 dries the biomass fuel 5 above the drying coil 2.

[0046] To further optimize the above technical solution, a connector 7 is installed at the top of the storage tank 1, which is connected to the solar collector 6. The connector 7 can be a clamp, and it is bolted to the storage tank 1. The frame of the solar collector 6 is bolted to the crossbeam 8, and the connector 7 is bolted to the crossbeam 8. This installation method ensures that the solar collector 6 is installed securely without compromising the waterproofing of the roof of the storage tank 1.

[0047] To further optimize the above technical solution, the solar collector 6 is connected to a crossbeam 8, and the crossbeam 8 is connected to the connector 7.

[0048] To further optimize the above technical solution, a concrete layer 9 is laid on the ground of the silo 1, and the drying coil 2 is embedded inside the concrete layer 9. The concrete layer 9 is filled with steel fiber reinforced concrete and steel mesh to improve its load-bearing capacity.

[0049] To further optimize the above technical solution, a partition joint 10 is provided around the drying area on the bottom surface of the silo 1. The partition joint 10 is located on the ground and can separate the drying area from the ground of other areas of the silo 1.

[0050] To further optimize the above technical solution, a rope 11 is installed on the top of the drying hood 4 to drive its lifting and lowering. The rope 11 is connected to the top of the silo 1, and a lifting device is connected to the rope 11. The lifting device is existing equipment, as long as it can drive the drying hood 4 to move up and down. When drying is required, the drying hood 4 covers the biomass fuel for drying; when drying is not required, the drying hood 4 is raised to the top of the silo 1 to avoid affecting the storage of biomass fuel.

[0051] To further optimize the above technical solution, a ventilation device 12 is installed on the side wall of the drying hood 4. The ventilation device can be a fan, with an air outlet on the drying hood 4. The drying hood 4, equipped with the ventilation device, forms a simple drying kiln system with good heat preservation performance, providing a stable temperature and humidity environment. The ventilation device promotes air circulation inside the drying hood 4, ensuring uniform humidity distribution, and discharges the evaporated moisture from the drying hood 4, achieving rapid evaporation of excess moisture from biomass fuel and meeting production process requirements.

[0052] To further optimize the above technical solution, a dustproof mesh window 012 is installed on the side wall of the silo 1.

[0053] To further optimize the above technical solution, a feeding port 013 is provided on the side wall of the silo 1.
