[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Refer to Figures 1-6 , an intelligent and automatic high-precision air distribution device for boiler combustion disclosed by the present invention, includes a boiler water tank 1 and an airflow flame stabilization component 2. The airflow flame stabilization component 2 is installed below the boiler water tank 1. The airflow flame stabilization component 2 includes a combustion outer shell 201 fixedly sleeved below the boiler water tank 1, a first annular exhaust pipe 202 and a second annular exhaust pipe 203 surrounding the outside of the boiler water tank 1. The combustion outer shell 201 can facilitate the enclosure of the flame, and the first annular exhaust pipe 202 and the second annular exhaust pipe 203 can facilitate the transportation of the flue gas. A plurality of first smoke dispersion pipes 204 arranged annularly are fixedly installed below the first annular exhaust pipe 202. The first smoke dispersion pipes 204 can connect the combustion outer shell 201 and the first annular exhaust pipe 202. Each first smoke dispersion pipe 204 is fixedly penetrated through the top surface of the combustion outer shell 201. A plurality of second smoke dispersion pipes 205 arranged annularly are installed between the first annular exhaust pipe 202 and the second annular exhaust pipe 203. The second smoke dispersion pipes 205 can connect the first annular exhaust pipe 202 and the second annular exhaust pipe 203. The first smoke dispersion pipes 204 and the second smoke dispersion pipes 205 are arranged at intervals. A support plate 206 located below the boiler water tank 1 is fixedly installed inside the combustion outer shell 201. The support plate 206 can support the flame limiting cylinder 207. A plurality of flame limiting cylinders 207 located below the boiler water tank 1 inside the combustion outer shell 201 are fixedly installed on the support plate 206. The flame limiting cylinder 207 can facilitate the azimuth limitation of the flame.

[0032] When the air inside the annular exhaust pipe two 203 flows upward, it can drive the air inside each smoke-dispersing pipe two 205 to flow upward. The upward flow of the air inside each smoke-dispersing pipe two 205 can drive the air inside the annular exhaust pipe one 202 to flow upward. The upward flow of the air inside the annular exhaust pipe one 202 can drive the air inside each smoke-dispersing pipe one 204 to flow upward. The upward flow of the air inside the smoke-dispersing pipe one 204 can drive the air inside the combustion outer shell 201 to flow upward. The flame limiting cylinders 207 inside the combustion outer shell 201 are evenly arranged below the boiler water tank 1. The air inside the combustion outer shell 201 below the support plate 206 flows upward through each flame limiting cylinder 207, and the flame rises upward through each flame limiting cylinder 207. There is a flame inside each flame limiting cylinder 207, which can fully heat the bottom of the boiler water tank 1 and prevent the flame from deviating to one side. Due to the arrangement of each smoke-dispersing pipe one 204 and each smoke-dispersing pipe two 205, the flue gas can enter the annular exhaust pipe one 202 through each smoke-dispersing pipe one 204. The annular exhaust pipe one 202 can damp and block the flue gas, and then the flue gas enters the annular exhaust pipe two 203 through each smoke-dispersing pipe two 205. This process can evenly distribute the flue gas and air flow, which is beneficial to the stable discharge of the air flow in the space above the support plate 206 inside the combustion outer shell 201 and beneficial to the even distribution of the flame.

[0033] Referring to Figures 1-3 and Figure 5 In this embodiment, an air delivery assembly 3 is installed on the combustion outer shell 201. The air delivery assembly 3 is used to deliver air. The air delivery assembly 3 includes an air collecting hood 301 installed inside the combustion outer shell 201 and an air inlet pipe 302 penetrating through the side wall of the combustion outer shell 201. The air collecting hood 301 can facilitate the collection of air. The air inlet pipe 302 can deliver air to the connecting pipe 304. An air dispersion net 303 is fixedly installed inside the air collecting hood 301. The air dispersion net 303 can disperse the air entering the inside of the air collecting hood 301 from the connecting pipe 304. A connecting pipe 304 fixedly connected to the air inlet pipe 302 is fixedly installed below the air collecting hood 301. The connecting pipe 304 can facilitate the delivery of air to the air collecting hood 301. A valve one 305 located below the air inlet pipe 302 is installed inside the connecting pipe 304. The valve one 305 can facilitate the closing and opening of the connecting pipe 304. A blower one 306 is fixedly installed on the air inlet pipe 302. The blower one 306 can facilitate the delivery of air to the air inlet pipe 302.

[0034] Open valve 1 305, and deliver air to the air inlet pipe 302 by starting fan 1 306. The air inside the air inlet pipe 302 enters the air collecting hood 301 through the connecting pipe 304 and valve 1 305. The air inside the air collecting hood 301 is dispersed by the air dispersion net 303, and the dispersed air evenly flows into the internal space of the combustion housing 201 below the fuel support net 5, capable of conveying and processing the fuel on the fuel support net 5.

[0035] Refer to Figures 1-3 and Figure 6 , an ash storage component 4 is installed on the combustion housing 201 of this embodiment. The ash storage component 4 is used to store ash. The ash storage component 4 includes an ash collecting hood 401 fixedly installed below the connecting pipe 304 and inside the combustion housing 201, an ash discharge pipe 402 passing through the side wall of the combustion housing 201, and a storage box 403 located on one side of the combustion housing 201. The ash collecting hood 401 can collect ash. The ash discharge pipe 402 can connect the ash collecting hood 401 and the storage box 403. The storage box 403 can conveniently store ash. The ash discharge pipe 402 is installed between the ash collecting hood 401 and the storage box 403. A valve 2 404 is installed inside the ash discharge pipe 402. The valve 2 404 can conveniently close and open the ash discharge pipe 402. A conical ash-dispersing surface 405 is provided on the inner bottom surface of the ash collecting hood 401. The conical ash-dispersing surface 405 can conveniently limit the flow of ash. A fan 2 406 is fixedly installed inside the storage box 403. The fan 2 406 can drive the air flow inside the storage box 403.

[0036] When valve 1 305 is open and valve 2 404 is closed, it is convenient to deliver air to the air collecting hood 301 at this time. When valve 1 305 is closed and valve 2 404 is open, it is convenient to clean the ash at this time. The ash on the fuel support net 5 falls into the interior of the air collecting hood 301, and then the ash passes through the air dispersion net 303 and the connecting pipe 304 and falls into the interior of the ash collecting hood 401. The ash falling into the interior of the ash collecting hood 401 slides down along the conical ash-dispersing surface 405, which can prevent ash from accumulating inside the ash collecting hood 401 below the connecting pipe 304 and prevent the connecting pipe 304 from being blocked. Valve 1 305 is closed and valve 2 404 is open. By starting fan 1 306 to deliver air to the air inlet pipe 302, at the same time, fan 2 406 is turned on to drive the air inside the ash discharge pipe 402 to flow towards the storage box 403. The air flow inside the air inlet pipe 302 can blow the ash inside the ash collecting hood 401. The ash inside the ash collecting hood 401 can float towards the inside of the ash discharge pipe 402 according to the air flow. The ash inside the ash discharge pipe 402 enters the interior of the storage box 403 through the valve 2 404 along with the air flow, and the ash can be stored.

A dust-proof filter cloth bag 9 is fixedly installed inside the exhaust pipe 8, and the dust-proof filter cloth bag 9 can prevent the ashes inside the storage box 403 from overflowing.

[0040] Refer to Figure 1 and Figures 3-4 , a fuel addition port 10 is provided on the side wall of the combustion housing 201 of this embodiment, and the fuel addition port 10 can facilitate the addition of fuel into the combustion housing 201.

[0041] Refer to Figures 1-3 , above the combustion housing 201 of this embodiment, a heat-insulating housing 11 sleeved outside the boiler water tank 1 is fixedly installed. The heat-insulating housing 11 can protect the annular exhaust pipe one 202, the annular exhaust pipe two 203, the smoke-dispersing pipe one 204 and the smoke-dispersing pipe two 205.
