Description

Technical Field

[0001] This utility model relates to the technical field of biomass fuel heating equipment, and in particular to a biomass pyrolysis charcoal block fuel stove. Background Technology

[0002] Biomass pyrolysis is a thermal conversion technology that involves pressing biomass raw materials such as plant straw, wood scraps, corn cobs, and peanut shells into briquettes and heating them in a closed, oxygen-deficient or inert gas environment to produce combustible gas, charcoal, and liquid bio-oil. Bio-oil can be used as fuel or as a chemical raw material for refining chemicals, replacing fossil fuels. The combustible gas can be used for reactor heating or power generation, and the hydrogen-rich gas can be purified and utilized. Pyrolysis biochar is an environmentally friendly charcoal block that can be used as a soil conditioner, adsorbent, or further processed into activated carbon for carbon sequestration or environmental protection materials. Its primary use is as domestic fuel in areas without natural gas pipelines. Currently, there are no specialized stoves for using biomass pyrolysis charcoal blocks as fuel. Burning pyrolysis biochar blocks in ordinary stoves has the following drawbacks: First, the thermal energy utilization rate is low, resulting in significant waste of broken charcoal blocks and compromised kitchen hygiene. Second, carbon monoxide poisoning tragedies occur frequently. Third, many homes, public places, and office buildings rely on air conditioning or electric stoves for heating, which is costly and inefficient. Biochar blocks have the advantages of high calorific value, light weight, low ash content, and no smoke pollution when burned, so promoting the use of environmentally friendly biochar blocks in heating and daily life is of great significance.

[0012] This utility model provides a biomass pyrolysis charcoal block fuel stove, which includes an upper furnace cover plate, a lower furnace cover plate, a heat collection plate, a furnace chamber, insulation cotton, and an ash bin located inside a box-type furnace shell. It also includes a heat collection and heating unit installed inside the box-type furnace shell. The heat collection and heating unit includes a main flue pipe, branch flue pipes, a heat-conducting plate, and a heat-conducting baffle. The main flue pipe is frustoconical and connected to the furnace chamber.

[0013] The beneficial technical effects of this utility model are as follows: First, the stove is made of steel plate, and the heat collection plate can be made of steel plate or aluminum alloy plate as the heating source. It can be made into a flat plate for heating water and cooking, or into a crescent shape for stir-frying in an iron pot. The heat energy is highly efficient and pollution-free, making life more convenient for residents in mountainous areas. Second, because the biomass pyrolysis char blocks have a high calorific value when burned in this stove, and the upper fan is turned on, hot air is blown out from the heat conduction plate and warm air plate on the heat collector, which can make full use of the heat in the furnace for heating in winter, improving the quality of life in rural mountainous areas. Third, the use of a miniature noiseless fan for blowing air and oxygen supply provides rapid heating, and the temperature can be adjusted. Fourth, the insulation cotton filled in appropriate positions in the combustion chamber can insulate and keep the temperature of the outer layer of the stove below 30 degrees Celsius, while also saving energy.

[0014] Calculations show that each kilowatt-hour of electricity generates 860 kilocalories of heat, while high-quality biomass pyrolysis char blocks generate over 6800 kilocalories per kilogram. The calorific value of each kilogram of char blocks is equivalent to 8 kilowatt-hours of electricity. Comparing the price of electricity at 0.56 yuan per kilowatt-hour and the price of char blocks at 2 yuan per kilogram, using char heating is equivalent to 44.6% of the cost of electric heating. This invention has economic and energy-saving and emission-reduction effects, and can broaden the utilization of clean energy (biomass pyrolysis char blocks), which has significant economic and environmental benefits.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-8 As shown, this utility model provides a biomass pyrolysis charcoal block fuel stove, the usage of which is as follows: This utility model is suitable for, but not limited to, the following applications: 1. Heating; 2. Heating plus cooking (boiling water, stir-frying); 3. Cooking (boiling water, stir-frying). Specific usage steps are as follows:

[0026] First, pull out the pull-out panel 3. Because a flat plate that can slide in and out on the large slide 29 is connected to the bottom of the ash hopper 31, and the flat plate is fixedly connected to the pull-out panel 3, the flat plate pulls the ash hopper 31 out together. Then the ash hopper 31 can also be pulled out horizontally on the flat plate (see...). Figure 8This design facilitates the cleaning of carbon ash and dirt. The ash bin 31 retracts onto the flat plate, and then the pull-out panel 3 is pushed in, returning the ash bin 31 to its original position. The removed carbon ash can be used to make high-quality organic fertilizer. Extending the exhaust pipe 12 outdoors helps prevent carbon monoxide poisoning. The upper furnace cover 11, lower furnace cover 13, and bottom support plate 4 can be opened as needed. Leveling is achieved using the support legs 22, creating a ready-made stove and small dining table suitable for home or outdoor use.

[0027] Step 2: Check if the battery has sufficient power.

[0028] Step 3: (see...) Figure 2 The already lit red-hot charcoal is inserted into the furnace chamber 33. Because the gravity-fed air intake plate 40 has a pivot above the middle and is hinged inside the air intake frame, it normally remains vertical due to gravity. When the lower air intake fan 20 is activated, the gravity-fed air intake plate 40 is blown up, and the air enters the furnace chamber 33 through the ventilation channel 30 and the ventilation holes 41 on the ash bin 31, ensuring that the charcoal on the grate burns completely. Maintain the low-speed operation for 15 minutes to allow the charcoal fire to enter a normal combustion state.

[0029] Step 4: (See) Figure 2 In summer, when heating is not provided, the upper intake fan 16 is de-energized, and the self-weight air intake plate 40 and the warm air plate 7 are closed. Most of the heat rises and heats the heat collector plate 24, resulting in high thermal efficiency. A pot can be placed on the heat collector plate 24 for stir-frying or cooking. In winter, when heating is provided, the warm air switch 8 and the warm air plate switch 10 are turned on, allowing for simultaneous heating, cooking, stir-frying, hot pot, or even brewing tea around the fire. In winter, the temperature can be adjusted as needed by changing the angle of the warm air plate 7 using the heating setting knob 9, and also by adjusting the airflow from the lower intake fan 20 and the opening and closing of the fire shut-off plate 35.

[0030] Two heat-closing plates 35 are slidably installed in the guide rail groove 34. A handheld tool can be used to open and close the two heat-closing plates 35 to achieve temperature control. Alternatively, an electromagnet can be used to drive the heat-closing plates 35 to adjust the stove temperature. The heat-closing plates 35 are made of high-temperature resistant alloy material with added heat insulation cotton and equipped with small wheels. The electromagnet can have a pulling force of 10N, equivalent to more than 1 kg, providing sufficient power. This structure allows for automatic shut-off of rice using an electric rice cooker, while also producing the flavor of rice cooked over a wood fire, achieving intelligent and automated operation of the stove. The upper stove cover 11 and lower stove cover 13 are connected to the upper sides of the box-type stove shell 15 using a small round tube (approximately 5mm in diameter) as an axle, with an ear welded to each of the four corners.

[0031] Based on the disclosure and teachings of the above specification, those skilled in the art can make appropriate changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
