Description

Technical Field

[0001] This utility model relates to the field of biomass combustion heating technology, specifically to an automatic control heating device for biomass combustion. Background Technology

[0002] Biomass combustion technology refers to the process of crushing coal and combustible biomass into a certain particle size and drying it to a certain degree, mixing them in a certain proportion, and using a straw briquetting machine to compress the biomass by compressing the lignin, cellulose, hemicellulose and other components that differ from the coal in binding properties. When used for combustion heating, a heating device is required.

[0003] Traditional automatic heating equipment adjusts the heating temperature by changing the size of the combustion flame. This leads to incomplete combustion when the flame becomes smaller, producing toxic carbon monoxide gas. When carbon monoxide is released directly into the air, it can cause poisoning or explosions, and also wastes energy, thus causing inconvenience to users. Utility Model Content

[0011] This invention provides an automatically controlled heating device for biomass combustion. It offers the following advantages: This automatically controlled heating device for biomass combustion utilizes a waste gas treatment unit.

[0019] 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.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] Traditional automatic heating equipment adjusts the heating temperature by changing the size of the combustion flame. This leads to the production of toxic carbon monoxide gas when the flame becomes smaller and combustion is incomplete. When carbon monoxide is released directly into the air, it can cause poisoning or explosions, and also wastes energy, thus causing inconvenience to users.

[0022] In view of this, the present invention provides an automatic control heating device for biomass combustion. This automatic control heating device for biomass combustion uses a waste gas treatment device. After the device burns biomass, the carbon monoxide gas produced is re-ignited by the waste gas treatment device. Then, the residual carbon monoxide is adsorbed and treated with a carbon monoxide catalyst. This can prevent carbon monoxide gas from being discharged outside the device and causing harm to human health and the environment. It also reduces the risk of accidents and ensures the utilization rate of energy materials.

[0023] Example 1: By Figure 1 , 2As shown in section 3, an automatic control heating device for biomass combustion includes a housing 1. A discharge port 6 is connected to the upper side of one side of the housing 1. A controller 7 is fixedly connected to the top of the housing 1 near the discharge port 6. The model of the controller 7 is not limited, as long as it meets the usage requirements. An oxygen supply device 3 is installed on the bottom of the housing 1 away from the discharge port 6. An exhaust gas treatment device 2 is installed inside the upper part of the housing 1. The exhaust gas treatment device 2 includes: a first support plate 21, fixedly connected to the inner wall of the housing 1; multiple exhaust holes 22, all equally spaced on the side of the first support plate 21 away from the discharge port 6; a first protective shell 23, installed on the top of the first support plate 21 near the discharge port 6; an electronic igniter 24, model XLGND-12, located inside the first protective shell 23, with the ignition end extending above the first protective shell 23; and a vertical plate 25. The first support plate 21 is fixedly connected to the top of the first support plate 21 near the exhaust port 6 and is attached to the inner wall of the box 1; the carbon monoxide catalyst 26, whose main components are copper oxide and manganese dioxide, is located inside the box 1 on the upper side near the exhaust port 6 and is attached to the top of the first support plate 21 near the exhaust port 6; the first filter screen 27, whose mesh size is not limited as long as it meets the usage requirements, is fixedly connected to the upper side of the inner wall of the box 1 near the exhaust port 6 and is fixedly connected to the top of the first support plate 21 near the exhaust port 6; wherein, when the carbon monoxide produced by biomass combustion passes through the first support plate 21 through multiple exhaust holes 22, the electronic igniter 24 ignites the carbon monoxide for secondary combustion, the carbon monoxide catalyst 26 adsorbs the carbon monoxide, and the first filter screen 27 filters the ash produced by combustion;

[0024] In the specific implementation process, it is worth noting that this case should be equipped with an external temperature detection device. The external temperature detection device can be connected to the controller 7 via Bluetooth or other means to quickly provide the controller 7 with the external temperature information. Then the controller 7 can control the air intake of the fan 34 to change the heating temperature. Bluetooth connection and device control are existing known technologies, so they will not be elaborated on. The outer wall of the box 1 is provided with a wall door. Workers can put biomass into the box 1 by opening the wall door. When burning biomass, workers close the wall door to prevent the heat generated by biomass combustion from being discharged through the wall door. The first protective shell 23 can protect the electronic igniter 24. The vertical plate 25 has through holes, and heat can pass through the vertical plate 25 through the through holes. Workers need to replace the carbon monoxide catalyst 26 and the first filter screen 27 regularly to prevent the carbon monoxide catalyst 26 and the first filter screen 27 from decreasing in effectiveness after long-term use. The first filter screen 27 can block the ash generated by biomass to prevent it from entering the surrounding environment through airflow.

[0025] Specifically, when using the automatic control heating equipment for biomass combustion, the worker first opens the wall door of the box 1, then puts the biomass inside the box 1, and then ignites the biomass. When the biomass burns, it produces heat energy and carbon monoxide gas. This heat energy and carbon monoxide gas will pass through the first support plate 21 through multiple exhaust holes 22. At this time, the worker controls the electronic igniter 24 through the controller 7 to perform ignition. The flame generated by the electronic igniter 24 can ignite the carbon monoxide gas a second time. Through the second ignition, the carbon monoxide gas will be converted into carbon dioxide, thereby purifying the exhaust gas. After the heat energy and the gas converted into carbon dioxide pass through the vertical plate 25, the heat energy will continue to pass through the carbon monoxide catalyst 26. When the heat energy passes through the carbon monoxide catalyst 26, the carbon monoxide catalyst 26 will convert the remaining carbon monoxide into harmless substances. Then the heat energy will pass through the first filter screen 27. The first filter screen 27 will block the ash carried in the heat energy. After the filtered heat energy passes through the first filter screen 27, the heat energy will be discharged from the interior of the box 1 through the exhaust port 6.

[0026] Example 2: From Figure 2 and 4 It is known that the oxygen supply device 3 includes: a first outer shell 31, installed on the lower side of the box 1 away from the exhaust port 6; a second filter screen 32, the mesh size of the second filter screen 32 is not limited, as long as it meets the usage requirements, and is fixedly connected to the inner wall of the first outer shell 31 by bolts; an air inlet 33, machined on the lower side of the box 1 near the first outer shell 31; and a fan 34, the model of the fan 34 is YNF-200-2T, fixedly connected to the lower side of the box 1 near the first outer shell 31, and the output end extends to the lower interior of the box 1; wherein, the fan 34 sends outside air into the interior of the box 1 through the air inlet 33, and the second filter screen 32 prevents impurities from entering the interior of the first outer shell 31;

[0027] In the specific implementation process, it is worth noting that workers need to replace the second filter screen 32 regularly to avoid the filtration effect of the second filter screen 32 decreasing after long-term use. The working status of the fan 34 can be adjusted by the controller 7 to change the oxygen supply, thereby adjusting the flame size and achieving temperature control.

[0028] Specifically, based on the above embodiment one, after the worker ignites the biomass, the worker controls the blower 34 to perform air supply operation through the controller 7. The blower 34 will draw outside air into the interior of the first outer shell 31. When the outside air passes through the first outer shell 31, the impurities in the air will be blocked by the second filter screen 32. The filtered air, under the influence of the blower 34, will enter the interior of the box 1 from the air inlet 33, thereby keeping the air inside the box 1 sufficient. Sufficient air can enable the biomass to burn continuously.

[0029] Example 3: From Figure 1 , 2 As can be seen from points 4 and 5, a dust removal device 4 is provided below the exhaust gas treatment device 2. The dust removal device 4 includes: two limiting plates 41, which are fixedly connected to the lower sides of the inner wall of the housing 1; two grooves 42, which are machined inside the two limiting plates 41; a second support plate 43, which fits into the grooves 42 inside the two limiting plates 41; multiple ash discharge holes 44, which are machined at equal intervals on the inner wall of the second support plate 43; a second outer shell 45, which is fixedly connected to the lower side of the outer wall of the housing 1 away from the first outer shell 31; and a crossbar 46, which is inserted into the inner wall of the second outer shell 45 and close to the discharge port 6 of the inner wall of the housing 1. The crossbar 46 is inserted into the lower side of the second support plate 43. One end of the crossbar 46 is fixedly connected to the outer wall of the second support plate 43 near the discharge port 6. The spring 47 is sleeved on the outer wall of the crossbar 46 away from the second support plate 43, and both ends are respectively abutted against the inner wall of the second outer shell 45 and the outer wall of the crossbar 46. The baffle 48 is fixedly connected to the lower side of the inner wall of the box 1 near the first outer shell 31. When the worker pulls the crossbar 46, the spring 47 inside the second outer shell 45 is compressed. At the same time, the second support plate 43 is subjected to force and begins to move along the inside of the two grooves 42. At this time, the ash produced by the biomass combustion above the second support plate 43 will fall from multiple ash discharge holes 44.

[0030] In the specific implementation process, it is worth noting that when biomass is burned above the second support plate 43, the two limiting plates 41 support the second support plate 43 and the biomass. The top of the second support plate 43 between the two ash discharge holes 44 is curved, which makes it easier for ash to fall into the ash discharge holes 44. After the ash passes through the second support plate 43 from the multiple ash discharge holes 44, the workers need to replace the spring 47 regularly to prevent the elastic potential energy of the spring 47 from decreasing after long-term use. The baffle 48 can block the ash and prevent it from entering the fan 34. The side of the box 1 is provided with a wall door for ash discharge. The bottom of the box 1 is sloping, which makes it easier for the ash to slide towards the side wall door.

[0031] Specifically, based on the above embodiment one, after the biomass is completely burned, a large amount of ash is produced. At this time, the worker can pull the crossbar 46 away from the container 1. When the crossbar 46 is under force, it will move along the inner wall of the second outer shell 45. At this time, the spring 47 begins to compress itself due to the movement of the crossbar 46. At the same time, the second support plate 43 begins to move along the inside of the two grooves 42 under force. At this time, the ash above the second support plate 43 is affected by the movement of the second support plate 43 and begins to fall into the inside of the multiple ash discharge holes 44. Then the worker releases the crossbar 46, and the spring 47 is no longer under force. The crossbar 46 is moved towards the box 1. At the same time, the crossbar 46 pushes the second support plate 43 to move along the inside of the two grooves 42. At this time, the dust above the second support plate 43 is affected by the movement of the second support plate 43 and will continue to fall into the inside of the multiple dust discharge holes 44. The worker can repeat the above operation multiple times until all the dust is discharged from the multiple dust discharge holes 44. The dust will fall to the bottom of the box 1 and then slide along the slope of the bottom of the box 1 towards the side door of the box 1. Finally, the worker can open the side door of the box 1 to discharge the dust into the box 1.

[0032] Example 4: From Figure 1 and 2 It is known that a water heating device 5 is installed above the ash removal device 4. The water heating device 5 includes: a water storage tank 51, which is fixedly connected to the upper side of the inner wall of the tank body 1 away from the discharge port 6 and is fixedly connected to the top of the vertical plate 25; a valve 52, which is connected to the upper side of the tank body 1 away from the discharge port 6; a water pipe 53, which passes through the top of the tank body 1 away from the discharge port 6 and extends to the lower part of the tank body 1, and passes through the water storage tank 51 away from the vertical plate 25, and the water pipe 53 passes through the first support plate 21 away from the discharge port 6; a second protective shell 54, which is installed on the top of the tank body 1 away from the discharge port 6; and a high-temperature pump 55, which is fixedly connected to the inner wall of the second protective shell 54 by bolts, and the input end is connected to the end of the water pipe 53. The heated water source is drawn out by the high-temperature pump 55 and heated by the external water heating device. The heated water flows back to the interior of the water storage tank 51 through the valve 52.

[0033] In the specific implementation process, it is worth noting that this case should be equipped with appropriate heating radiator functions and other equipment, and the external heating equipment can be connected to valve 52 and high-temperature pump 55 to realize the recycling of water source. The specific selection of the external heating equipment can be determined according to actual usage needs, and there are no restrictions here. Moreover, this is existing known technology, so it will not be elaborated in detail. Those skilled in the art should have a broad understanding. The model of high-temperature pump 55 is: AMC65-40-200. The second protective shell 54 is processed with heat dissipation holes. When the high-temperature pump 55 is operating, it can dissipate heat from the second protective shell 54 through the heat dissipation holes. The second protective shell 54 is equipped with a wall door. When the worker needs to repair the high-temperature pump 55, he only needs to open the wall door of the second protective shell 54.

[0034] Furthermore, multiple heat-conducting fins 511 are equidistantly installed at the bottom of the water storage tank 51;

[0035] In the specific implementation process, it is worth noting that multiple heat-conducting plates 511 can quickly heat up the water inside the water storage tank 51.

[0036] Specifically, based on the above embodiment one, when heating is being carried out, the staff turns on the control device of the high-temperature pump 55. At this time, the high-temperature pump 55 can draw water from the water storage tank 51 and then deliver it to the external heating equipment. At this time, the external heating equipment can be used to realize the heating operation. After the heating is completed, the water flows back into the water storage tank 51 through the valve 52 for reheating, thereby realizing circulating heating.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
