Description

Technical Field

[0001] The utility model relates to the technical field of hard carbon production, in particular to a biomass carbonized volatile matter heat source incineration device. Background Art

[0002] Biomass carbonization volatiles are a gas mixture produced after high-temperature carbonization and pyrolysis of biomass, which contains a variety of organic compounds and trace elements. These substances usually have high combustion temperatures and combustion rates, so they require special treatment and utilization methods. Common treatment methods for biomass carbonization volatiles include chimney emissions, smoke collection and filtration, smoke purification and combustion recovery, among which combustion recovery is to redirect the smoke emitted by the carbonization furnace into the combustion chamber or combustion equipment for combustion to reduce the release of harmful gases. This method can burn the organic matter in the smoke into carbon dioxide and water vapor, and use the heat generated as energy. It can also reduce the emission of ash and other impurities and improve energy utilization.

[0003] However, there are incompletely burned substances in the exhaust gas after carbonization. After the exhaust gas enters the incineration device, the unburned substances in the exhaust gas will adhere to the inner wall, causing the unburned substances to form a deposition layer in the pipeline, which will not only cause gas flow obstruction and affect the normal flow of exhaust gas in the pipeline, but the accumulation of unburned substances will also increase the instability and danger of the equipment, which may cause equipment failure, reduced efficiency or even shutdown. Secondly, the acidic or alkaline components of the unburned substances will corrode the inner wall, accelerate pipeline aging, and shorten the service life of the equipment.

[0004] Therefore, there is an urgent need for an incineration device that can improve incineration efficiency and reliability and extend the service life of the equipment. Utility Model Content

[0036] Example:

[0037] like Figures 1 to 9 As shown, a biomass carbonized volatile matter heat source incineration device comprises:

[0038] Casing 1, burner body 2 and impeller 3;

[0039] A combustion port 11 is disposed at one end of the shell 1, a sealing cover plate 12 is disposed at the other end of the shell 1, and an exhaust gas inlet pipe 13 is disposed at the bottom of the shell 1 near one end of the sealing cover plate 12;

[0040] The burner body 2 and the impeller 3 are both located in the housing 1. The burner body 2 includes a combustion chamber 21, a gas pipeline 22 and an air pipeline 23. The combustion chamber 21 is arranged on a side close to the combustion port 11. The gas pipeline 22 and the air pipeline 23 extend from the combustion chamber 21 to the sealing cover plate 12. The gas pipeline 22 is penetrated on the air pipeline 23. One end of the gas pipeline 22 and the air pipeline 23 are connected to the combustion chamber 21, and the other end of the air pipeline 23 is penetrated on the sealing cover plate 12.

[0041] The impeller 3 is sleeved on the burner body 2, and the impeller 3 includes a plurality of groups of vertical blades 31 and a plurality of groups of rotating blades 32. The vertical blades 31 are perpendicularly arranged to the inner wall of the shell 1, and the vertical blades 31 are evenly distributed along the circumferential direction of the burner body 2. The vertical blades 31 are fixedly connected to the rotating blades 32, and the rotating blades 32 are spirally arranged around the air duct 23. The impeller 3 rotates around the burner body 2 in the shell 1 to guide the exhaust gas to the combustion chamber 21.

[0042] Furthermore, the impeller 3 adopts a centrifugal structure, which is installed in the housing 1 and forms an integral body with the combustion chamber 21. This design enables the impeller to withstand the impact force of high-temperature and high-pressure gas flow and air flow, while also ensuring the rotational stability and reliability of the impeller.

[0043] Among them, a control valve 14 for controlling the exhaust gas flow is arranged in the exhaust gas intake pipe 13, and the control valve 14 includes a partition 141 and a rotating shaft 142. The partition 141 is rotatably arranged in the exhaust gas intake pipe 13 through the rotating shaft 142, and the rotating shaft 142 passes through the partition 141. A connecting plate 143 and a handle 144 are connected to the rotating shaft 142. A plurality of limiting holes 1431 are arranged in an arc shape on the connecting plate 143, and a limiting bolt 1441 is arranged on the handle 144. The limiting bolt 1441 cooperates with the limiting hole 1431 to limit the opening and closing angle of the partition 141.

[0044] In addition, a baffle 131 is disposed above the exhaust gas inlet pipe 13 . The baffle 131 is obliquely disposed in the housing 1 , and the flow direction of the exhaust gas is guided by the baffle 131 .

[0045] In addition, an observation port 121 is provided on the sealing cover plate 12, and an ultraviolet fire detection device 15 is provided on one side of the sealing cover plate 12. The ultraviolet fire detection device 15 is connected to the inner cavity of the shell 1 through a connecting pipe 16, and the connecting pipe 16 is penetrated on the sealing cover plate 12. The ultraviolet fire detection device 15 determines the size, shape and color of the flame by measuring the intensity of ultraviolet rays, thereby judging whether the temperature of the exhaust gas reaches a safe level and whether there are potential safety hazards.

[0046] Furthermore, the combustion chamber 21 includes a nozzle 211, an ignition device 212, a flame stabilizing plate 213 and a shell 214, the nozzle 211 and the flame stabilizing plate 213 are connected by threads, the nozzle 211 is sleeved on one end of the gas pipeline 22, one end of the ignition device 212 is passed through the flame stabilizing plate 213, the other end of the ignition device 212 is passed through the sealing cover plate 12, the flame stabilizing plate 213 and the air pipeline 23 are connected by bolts, one end of the shell 214 is arranged to abut against the shell 1, and vent holes 2141 are evenly opened on the shell 214, and the shell 214 is engaged with the impeller 3.

[0047] Among them, the flame stabilizing sheet 213 can enhance the combustion effect, improve the fuel utilization efficiency and improve the stability and controllability of combustion. The structure of the nozzle 211 and the flame stabilizing sheet 213 belongs to the prior art, and the specific structure will not be repeated here.

[0048] Furthermore, the ignition device 212 includes an ignition head 2121 and an ignition rod 2122 , the ignition head 2121 is connected to one end of the ignition rod 2122 , the ignition rod 2122 is extended along the axial direction of the shell 1 , and the ignition rod 2122 is parallel to the air duct 23 .

[0049] It should be noted that the impeller 3 also includes a first fixing ring 33 and a second fixing ring 34. The first fixing ring 33, the vertical blades 31 and the second fixing ring 34 are fixedly connected. The first fixing ring 33 is arranged to abut against the shell 1. A slot 35 is arranged at the connection between the second fixing ring 34 and the vertical blades 31. The slot 35 is arranged to engage with the combustion chamber 21.

[0050] The first fixing ring 33, the vertical blades 31 and the second fixing ring 34 are fixedly connected to form an integral structure, which can enhance the stability and wind resistance of the impeller 3 and reduce the vibration and impact of the impeller 3 during operation.

[0051] Furthermore, the outer edge of the rotating blade 32 is arranged in an arc shape, and the rotating blade 32 gradually narrows from the starting end to the end. The outer edge of the rotating blade 32 is arc-shaped, which can reduce the direct contact area with the airflow, thereby reducing the air resistance of the rotating blade 32, and the arc-shaped design enables the rotating blade 32 to pass through the air flow field more smoothly when rotating, reducing the friction and blockage between the rotating blade 32 and the air, and improving the efficiency and power output of the rotating blade 32.

[0052] Working process: the exhaust gas enters the shell 1 through the exhaust gas intake pipe, and the intake volume and flow rate of the exhaust gas are adjusted by the control valve 14. After the exhaust gas enters the shell 1, due to the blocking force of the baffle 131, the exhaust gas flows toward the combustion chamber along the inclined direction of the baffle 131. After the exhaust gas passes through the impeller 3, the impeller 3 rotates. The rotational motion of the impeller 3 accelerates the circulation speed of the exhaust gas and improves its fluidity. At the same time, after the impeller 3 rotates, the exhaust gas is concentrated in the combustion chamber. After the gas and air in the combustion chamber 21 are merged, they are ignited by the ignition device 212 to burn the unburned substances in the exhaust gas.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
