Description

Technical Field

[0001] The invention relates to the field of biomass fuel combustion equipment, and in particular to a mobile bottle biomass fuel gasifier. Background Art

[0002] Biomass fuel is the preferred natural renewable and clean energy to replace traditional energy such as petrochemical diesel, coal and other highly polluting fuels. Biomass energy is contained in organic matter that can grow, such as plants, animals and microorganisms. Biomass fuel can be divided into three categories: biomass solid fuel, biomass liquid fuel and biomass gas fuel.

[0003] The raw materials of biomass solid fuel usually include wood and forest waste, such as scattered wood, residual bark and wood chips in forestry felling, or branches, sawdust, wood chips, tips, board skin and cut ends in the process of wood harvesting and processing, or waste of forestry by-products, such as fruit shells and cores, as well as agricultural waste, such as waste in the agricultural production process, crop straw remaining in the farmland when crops are harvested, including corn straw, sorghum straw, wheat straw, bean straw, cotton straw, etc., and waste from agricultural processing industry, such as rice husks left over in the agricultural production process; raw materials of biomass liquid fuel such as livestock manure, industrial organic wastewater, urban domestic wastewater, etc.; the raw materials of the above-mentioned biomass solid fuel are pressed into high-density solid (granular) biomass solid fuel, or the raw materials of the above-mentioned biomass liquid fuel are processed into colorless, odorless, transparent liquid biomass liquid fuel or biomass gas fuel.

[0004] Biomass fuels are easy to burn, have high calorific value, produce no black smoke or soot, and burn completely. They are environmentally friendly, energy-saving, and safe energy.

[0005] However, due to the current rough use of biomass fuels, low thermal efficiency, poor emission indicators, etc., in addition to the quality problems of biomass fuels themselves, the main reason lies in the equipment used for biomass fuels. Almost all the existing biomass fuel heating equipment on the market is industrial heating equipment; the overall structure and functional design of the equipment cannot be used in places with high environmental requirements such as unit canteens, restaurants, various hotel kitchens and standard industrial heat supply. The existing equipment is large and cannot be moved, and can only work in specific locations. Especially in the process of adding fuel and cleaning ash, a lot of powder and dust are generated, which directly affects the working environment and hygiene.

[0006] Based on the reasons mentioned above, the scope of application of biomass fuel is limited. Therefore, the research and development of a bottle-type mobile biomass gasification furnace <stove> that is lightweight, easy to move, burns fully, and is clean, safe, economical, and convenient has practical application value. It can be set up by a dedicated person to install the fuel and clean the ash, and then a professional person to operate the equipment, and implement a distinction between the work site and specific staff, avoid the low efficiency and dust generation caused by cross-work, and achieve a dedicated, professional and standardized operation process, so that biomass fuel can be better and more widely used in the energy consumption market. Summary of the invention

[0007] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art.

[0008] A mobile bottle biomass fuel gasifier is provided.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a mobile bottle biomass fuel gasifier, comprising a furnace frame, a stove top arranged above the furnace frame and a gasifier body arranged below the furnace frame, a heating position for placing pots and stoves is arranged on the stove top, and the gasifier body is arranged below the heating position, characterized in that a bottom plate is arranged at the other end of the furnace frame opposite to the stove top, a bottom cover is arranged at one end of the gasifier body facing the bottom plate, at least three rollers are arranged on the bottom cover, and slideways for rollers to slide are arranged at positions corresponding to the rollers on the bottom plate, the gasifier body comprises a fuel storage barrel and a heat insulation layer concentrically arranged on the bottom cover, the heat insulation layer is arranged outside the fuel storage barrel and a gap is formed between the fuel storage barrel and the heat insulation layer, a combustion burner is arranged at the other end of the gasifier body opposite to the bottom cover, and the furnace frame is provided with a first auxiliary air inlet device connected to the combustion burner head and the heat insulation layer on one side of the gasifier body.

[0010] By adopting the above technical scheme, rollers are arranged on the bottom cover of the gasifier body, and slideways for the rollers to slide are arranged on the bottom plate. When the fuel in the gasifier body is exhausted and the gasifier body needs to be replaced, the gasifier body can be moved out along the slideway and replaced. The replacement speed is fast. A first auxiliary air inlet device connecting the insulation layer and the combustion burner head is arranged on one side of the furnace frame. On the one hand, a large amount of air can be transported to the combustion burner head when the biomass fuel is burning, so that the biomass fuel can be fully burned. On the other hand, natural cold air can be introduced into the insulation layer. Since the temperature in the fuel storage barrel is relatively high during operation, the introduction of cold air into the insulation layer can play a cooling role and generate hot air directly to the combustion burner head during the heat exchange as the oxygen required for combustion. Under the condition of cooling the furnace body, the waste heat is fully utilized, and the energy-saving effect is achieved, so as to prevent the temperature of the entire combustion furnace body from being too high, thereby causing safety hazards, such as when the gasifier body stops burning, the surface temperature is too high to be replaced, and the first auxiliary air inlet device is damaged.

[0011] The above-mentioned mobile bottle biomass fuel gasification furnace can be further configured as follows: the first auxiliary air inlet device includes an air inlet box body and a first blower arranged on one side of the air inlet box body and connected to the air inlet box body; the air inlet box body is provided with a first air outlet pipe at a position corresponding to the insulation layer and a second air outlet pipe at a position corresponding to the combustion burner; the insulation layer is provided with a first air inlet pipe connected to the first air outlet pipe and a second air inlet pipe connected to the second air outlet pipe; the first air outlet pipe and the second air outlet pipe are both equipped with flow regulating valves; a micro-oil ignition device is provided in the air inlet box body, one end of the micro-oil ignition device is connected to the combustion burner head; a second auxiliary air inlet device connected to the bottom cover is provided on the bottom plate.

[0012] By adopting the above technical scheme, the air volume discharged from the first air outlet pipe and the second air outlet pipe is adjusted by the flow regulating valve. When the flow regulating valve at the first air outlet pipe is opened and the flow regulating valve at the second air outlet pipe is closed, the air volume of the first blower will all enter the combustion burner head from the first air outlet pipe to assist combustion. Otherwise, the air volume will all enter the second air inlet pipe from the second air outlet pipe to cool the insulation layer before entering the combustion burner head. Regardless of whether the natural wind goes out from the first air outlet pipe or the second air outlet pipe, it must first pass through the air inlet box. Therefore, the micro-oil ignition device in the air inlet box is always in a state of being cooled by natural wind, ensuring that the temperature around the micro-oil ignition device is always at room temperature.

[0013] The above-mentioned mobile bottle biomass fuel gasification furnace can be further configured as follows: the second auxiliary air intake device includes a second blower, and the bottom cover is provided with a third air intake pipe connected to the second blower.

[0014] By adopting the above technical solution, a second blower is provided to ventilate the bottom cover, and the wind passes through the fuel storage barrel body and the combustion burner head in sequence from the bottom cover, thereby further improving the combustion efficiency.

[0015] The above-mentioned mobile bottle biomass fuel gasification furnace can be further configured as follows: the insulation layer is provided with an air inlet structure at the combustion burner head, the air inlet structure includes a plurality of air inlet grooves arranged at intervals circumferentially of the insulation layer, one side of the air inlet groove is connected to a first guide plate extending toward the combustion burner head, and a second air inlet structure is provided at the combustion burner head.

[0016] By adopting the above technical solution, the natural wind entering the heat insulation layer through the first air inlet pipe is guided by a plurality of air inlet grooves spaced circumferentially of the heat insulation layer and a first guide piece arranged at the air inlet groove, so that the firepower of the combustion burner head is more concentrated.

[0017] The above-mentioned mobile bottle biomass fuel gasification furnace can be further configured as follows: the second air inlet structure includes a plurality of second air inlet slots spaced circumferentially around the combustion burner head, and a second guide plate in the same direction as the first guide plate is connected to one side of the second air inlet slot.

[0018] By adopting the above technical solution, a second air inlet slot and a second guide piece in the same direction as the first guide piece are arranged on the combustion burner head to further improve the firepower concentration.

[0019] The beneficial effects of the present invention are: light in size, easy to move, making the biomass fuel burn more completely, and the firepower can be adjusted. The machine can be shut down in the middle and can be started again, achieving the effect of multiple gasification uses of a bottle of biomass fuel, producing gas while burning, without the risk of gas storage, straight-through air inlet and outlet structure, no pressure risk in the gasifier body, and stopping operation means stopping gas production, no gas, and no risk.
