Description

Technical Field

[0001] The present invention relates to the technical field of biomass boilers, and in particular to a gasification direct-combustion coupled integrated biomass boiler. Background Art

[0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water and land, including plants, animals and their excrement. In the energy field, it can be converted into biomass energy through combustion or fermentation, replacing fossil energy and reducing carbon emissions.

[0003] With the long-term and large-scale consumption of fossil energy, its reserves are decreasing, and concerns about the energy crisis are increasing. Countries have begun to actively seek renewable alternative energy sources. Biomass, as a renewable resource with abundant reserves on the earth, has the characteristics of wide sources and recyclability, providing a new path for energy supply. In the process of utilizing biomass energy, biomass boilers are needed to burn it.

[0004] At present, the biomass boilers on the market mainly use direct combustion to directly burn biomass fuel inside the boiler to generate heat energy, and through the use of heat energy, realize the utilization and development of biomass energy. However, during the use of the device, the direct combustion method usually directly burns biomass raw materials to generate heat. The energy conversion efficiency of this method is extremely low, and a large amount of energy will be lost in the form of ash waste heat, and the energy potential of biomass cannot be fully utilized. In order to solve the above problems, the existing technology uses stratified combustion technology to control the air supply and combustion temperature to ensure the full combustion of fuel and reduce monoxide. Carbon and black smoke emissions, but in the actual use of the device, the flue gas emitted still contains a large amount of combustible flue gas, resulting in energy waste. The existing technology adopts a gasification and direct combustion coupling method, which enables biomass fuel to be gasified and burned directly inside the furnace body to improve energy utilization efficiency. However, in the actual use of the device, when in use, the device completely relies on the heat released by the combustion of the fuel itself to maintain the gasification temperature, which will consume more raw materials for heating itself, resulting in a slowdown in the gasification speed and a decrease in the gas production efficiency per unit time, which reduces the combustion efficiency of the device and cannot meet the needs of users.

[0027] Working principle: When using this device, biomass fuel will burn on the top of the grate 21, and the high-temperature exhaust gas generated will pass through the flow tube bundle area 24 and enter the economizer 25. After the heat energy is recovered by the economizer 25, the fuel gas will pass through the recirculation pipe 26 and be sent into the wind chamber 23 through the air supply pipe 28 by the high-temperature and high-pressure fan 27. After the high-pressure air is heated by the grate 21, it penetrates the material evenly with strong penetration, and the hydrogen and oxygen content inside the high-pressure air is adjusted by the air regulating valve 292 and the hydrogen generator 291 to effectively control the generation of nitrogen oxides.

When the threaded rod 32 rotates, the support frame 33 is limited by the guide plate 38, and the support frame 33 drives the cleaning plate 34 to move leftward. And because the movable column 35 at the top of the cleaning plate 34 is limited by the guide rail 36, when the cleaning plate 34 moves to the left, it is pushed by the guide rail 36, which drives the cleaning plate 34 to move downward and insert into the slag. Then the first motor 31 drives the threaded rod 32 to reverse, and the cleaning plate 34 pushes the slag to move rightward, thereby pushing the slag out of the furnace shell 5, realizing automatic cleaning of the slag, and when the cleaning plate 34 moves to the far right, the spring 372 pulls the cleaning plate 34 to move upward, thereby realizing the cyclic cleaning of the slag. Finally, in the process of using this device, the gear 45 is driven to rotate by the second motor 44. Since the gear 45 is engaged with the rack 47, when the gear 45 rotates, the rack 47 will drive the water-cooled gate plate 1 46 to move, and the threaded column 483 is driven to rotate by the third motor 482. When the threaded column 483 rotates, the slider 484 will drive the water-cooled gate plate 2 485 to move. Through the movement of the water-cooled gate plate 1 46 and the water-cooled gate plate 2 485, the feeding of the feed hopper 1 41 and the feed hopper 2 42 can be controlled, and tempering can be prevented. The feeding amount can be controlled by the feed hopper 1 41, and the fuel height can be adjusted by the feed hopper 2 42, so that the amount and height of the fuel on the grate 21 are always within the optimal range.
