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

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] An integrated device for waste heat recovery and utilization of biomass gasification furnace includes a combustion furnace body 1, an exhaust component 2 connected to the top of the combustion furnace body 1, a waste heat recovery component 3 bolted to the bottom of the combustion furnace body 1, and a feeding component 4 fixedly connected to the top of the combustion furnace body 1.

[0027] The waste heat recovery assembly 3 includes a protective cover 301. A heat-conducting plate 302 is fixedly connected inside the protective cover 301. A heat-conducting pipe 303 is fixedly connected to the bottom of the heat-conducting plate 302. A housing 304 is fixedly connected to the surface of the heat-conducting pipe 303 away from the heat-conducting plate 302. A filling pipe 305 is connected to the top of the housing 304. A drain pipe 306 is connected to the bottom of the housing 304. A sealing block 307 is snapped into the inside of both the filling pipe 305 and the drain pipe 306.

[0028] In this embodiment: A combustion furnace body 1 serves as the core of the device, providing space for the combustion and vaporization of biomass fuel. An exhaust assembly 2 further filters the gas discharged from the combustion furnace body 1. A waste heat recovery assembly 3 recovers waste heat from the combustion furnace body 1. A feeding assembly 4 assists in moving biomass materials into the interior of the combustion furnace body 1. A protective cover 301 encloses the heat-conducting structure at the bottom of the combustion furnace body 1, preventing high-temperature fuel ash from splashing and damaging the heat-conducting components, and reducing heat loss through insulation design to ensure the biomass fuel is properly stored. The heat recovery efficiency is improved by setting up a heat-conducting plate 302 and a heat-conducting rod 5. The heat-conducting rod 5 extends directly into the combustion furnace body 1 and comes into contact with the high-temperature fuel ash, efficiently absorbing waste heat and conducting it to the heat-conducting pipe 303 through the heat-conducting plate 302. This solves the problem of traditional devices being unable to recover waste heat from the fuel after combustion, thus improving energy utilization. By setting up a heat-conducting pipe 303 and a housing 304, the heat-conducting pipe 303 transfers heat to the heat-conducting liquid, such as heat-conducting oil, inside the housing 304. The liquid is injected through the filling pipe 305 and discharged through the drain pipe 306. The heat-conducting liquid heats the air ducts inside the combustion furnace body 1, improving the gas efficiency.

[0029] Specifically, such as Figure 3 As shown, the feeding assembly 4 includes a support frame 401, a servo motor 402 is fixedly connected to the top of the support frame 401, and a stirring rod 403 is fixedly connected to the bottom of the servo motor 402. The stirring rod 403 is made of stainless steel.

[0030] Specifically, such as Figure 3 As shown, an auger 404 is fixedly connected to the surface of the stirring rod 403. The auger 404 is made of stainless steel.

[0031] Specifically, such as Figure 3 As shown, a protective sleeve 405 is fitted on the surface of the auger 404, and the protective sleeve 405 is made of silicone.

[0032] In this embodiment: By setting a support frame 401, the servo motor 402 and the stirring component are stably supported, ensuring the installation accuracy of the feeding component 4 and the combustion furnace body 1, and avoiding poor fuel delivery due to shaking. By setting a servo motor 402, power is provided to drive the stirring rod 403 and the auger 404 to rotate, realizing automated delivery of biomass fuel. Compared with manual feeding, it is more uniform and efficient, and improves combustion stability. By setting a stirring rod 403 and an auger 404, the stainless steel auger 404 rotates with the stirring rod 403, which can evenly stir the fuel and push it into the combustion furnace body 1, preventing fuel accumulation and promoting complete combustion. The spiral structure design of the auger 404 increases the contact area with the fuel and improves the feeding efficiency. By setting a protective sleeve 405, the silicone protective sleeve 405 is placed on the surface of the auger 404, which can buffer the friction between the fuel and the auger 404, reduce metal wear, extend the service life of the auger 404, and reduce noise during the feeding process.

[0033] Specifically, such as Figure 4 As shown, the exhaust assembly 2 includes a solenoid valve 201, the top of which is connected to a housing 202, and two filter plates 203 are slidably connected inside the housing 202.

[0034] Specifically, such as Figure 4 As shown, a top cover 204 is rotatably connected to the top of the box 202, and the top cover 204 is made of stainless steel.

[0035] In this embodiment: by setting a solenoid valve 201, the discharge of combustion gas can be flexibly controlled, which facilitates the adjustment of exhaust volume according to combustion conditions. At the same time, the airflow can be cut off during device maintenance to ensure operational safety. By setting a housing 202 and a filter plate 203, the filter plate 203 in the housing 202 can effectively intercept unburned particles and impurities in the combustion gas, avoiding direct emission and environmental pollution, while reducing the blockage of subsequent pipelines by particle accumulation. The slidingly connected filter plate 203 is easy to disassemble and clean, maintaining smooth exhaust. By setting a top cover 204, the stainless steel top cover 204 is rotatably connected to the housing 202, which facilitates quick opening of the housing 202 to replace or clean the filter plate 203, improving the convenience of device maintenance.

[0036] Specifically, such as Figure 5 As shown, a heat-conducting rod 5 is fixedly connected to the top of the heat-conducting plate 302, and the side of the heat-conducting rod 5 away from the heat-conducting plate 302 is connected to the interior of the combustion furnace body 1.

[0037] Specifically, such as Figure 1 As shown, a support leg 6 is fixedly connected to the bottom of the combustion furnace body 1, and an anti-slip pad 7 is fixedly connected to the bottom of the support leg 6.

[0038] In this embodiment: by setting a heat-conducting rod 5, which is connected to the interior of the combustion furnace body 1, the contact between the heat-conducting rod 5 and the biomass fuel inside the combustion furnace body 1 is improved. By setting a support leg 6, the combustion furnace body 1 and its components are supported to a suitable height, which facilitates the installation and maintenance of the bottom waste heat recovery component 3. At the same time, it avoids the device from directly contacting the ground and being damaged by moisture. By setting an anti-slip pad 7, the friction between the support leg 6 and the ground is increased, preventing the device from shifting due to vibration during operation, ensuring the stability of the overall structure and improving operational safety.

[0039] Working principle: When this integrated waste heat recovery and utilization device for biomass gasification furnace is working, the servo motor 402 of the feeding component 4 drives the stirring rod 403 and the auger 404 to rotate, stirring the biomass fuel and pushing it into the combustion furnace body 1 for combustion and gasification. The generated gas enters the box 202 through the solenoid valve 201 of the exhaust component 2, is filtered by the filter plate 203 and discharged. The burned biomass fuel accumulates at the bottom of the combustion furnace body 1. The heat-conducting rod 5 of the waste heat recovery component 3 extends into the furnace and contacts the high-temperature fuel. The absorbed waste heat is conducted through the heat-conducting plate 302 to the heat-conducting pipe 303, and then transferred to the heat-conducting liquid in the box shell 304. The liquid is injected through the filling pipe 305 and discharged through the drain pipe 306 to utilize the waste heat. The protective cover 301 protects and insulates the heat-conducting structure. The support legs 6 and anti-slip pads 7 at the bottom of the combustion furnace body 1 ensure the stability of the device. All components work together to realize the recovery and utilization of the waste heat of the burned biomass fuel, solving the problem of inconvenient waste heat recovery in traditional combustion furnace bodies 1.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
