Description

Technical Field

[0001] This invention relates to the field of chemical waste gas and wastewater treatment technology, specifically to a high-efficiency burner. Background Technology

[0002] The production process of chemical products often generates a large amount of waste gas and waste liquid, and most of the toxic and harmful waste gases require further advanced treatment. Due to the unique properties of some waste gases, these waste gases can only be rendered harmless by high-temperature incineration. However, waste gases are diverse in type and properties, and even if they are mixed according to their properties, there are still multiple waste gases. Ordinary burners cannot meet the requirement of simultaneously incinerating multiple waste gases.

[0003] Some waste liquids typically contain harmful components such as fluorine and chlorine. During the incineration process, slow temperature rise and slow combustion rate can lead to incomplete combustion, and may even produce highly toxic substances such as dioxins. Some waste liquids also contain nitriles with -CN cyano functional groups and amines with -NH-amino groups.

[0004] If the combustion intensity and temperature of these nitrogen-containing waste gases and liquids are too high, a large amount of fuel-type nitrogen oxides will be generated. Relying solely on subsequent tail-end flue gas denitrification treatment will result in high treatment costs, which will place a huge burden on enterprises and may lead to bankruptcy. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0039] like Figure 1As shown, a high-efficiency burner includes a combustion mechanism 2, a gas-assisted combustion mechanism 3, and a waste liquid injection and combustion mechanism 4. A connecting pipe 11 is welded onto the combustion furnace 1, which connects the furnace chamber inside the combustion furnace 1 to the external space. A flange 51 is provided on the end of the connecting pipe 11 away from the combustion furnace 1.

[0040] like Figures 1-6 As shown, the combustion mechanism 2 includes a combustion shell 21. A sandwich layer 22, a cast refractory layer 23, and a combustion chamber 24 are sequentially arranged within the combustion shell 21. The sandwich layer 22 is divided into multiple exhaust gas channels 221 and multiple combustion-supporting air ducts 222, and these channels are not interconnected. The exhaust gas channels 221 and combustion-supporting air ducts 222 have annular cross-sectional shapes. A cast refractory layer 23 is cast within the combustion shell 21 and is attached to the inner wall of the sandwich layer 22. During the incineration of exhaust gas and waste liquid, the cast refractory layer 23 protects the combustion shell 21, preventing damage from flames generated during incineration. The space formed within the cast refractory layer 23 can be considered as the combustion chamber 24 of the combustion shell 21, and the combustion chamber 24 is cylindrical in shape. A flange 51 is welded to one end of the combustion shell 21 near the combustion furnace 1. The flange 51 of the combustion shell 21 is installed and fixed to the flange 51 of the combustion furnace 1 with bolts, thus realizing the installation of the combustion mechanism 2 in the combustion furnace 1. The combustion chamber 24 of the combustion mechanism 2 is connected to the furnace chamber of the combustion furnace 1.

[0041] Optionally, such as Figures 2-6As shown, there are two combustion air ducts 222 and at least one exhaust gas passage 221. Two combustion air ducts 25 are welded to the outer surface of the combustion shell 21. The number of combustion air ducts 222 is the same as the number of combustion air ducts 25. One combustion air duct 222 is located at the end of the combustion shell 21 closest to the combustion furnace 1, and the same combustion air duct 25 is also located at the same end of the combustion shell 21, connected to the combustion air duct 222. The other combustion air duct 222 is located at the end of the combustion shell 21 furthest from the combustion furnace 1, and the same combustion air duct 25 is also located at the same end of the combustion shell 21, connected to the combustion air duct 222. The end of the combustion air duct 25 furthest from the combustion shell 21 can be considered as the combustion air inlet. The exhaust gas passage 221 is located between the two combustion air ducts 222. Combustion air enters the combustion chamber through combustion air ducts 222 on both sides of the exhaust gas passage 221, providing combustion support for the combustion of exhaust gas and waste liquid. Multiple exhaust gas pipes 26 are also welded to the outer surface of the combustion shell 21. Each exhaust gas passage 221 is connected to at least one exhaust gas pipe 26. The end of the exhaust gas pipe 26 furthest from the combustion shell 21 can be considered an exhaust gas interface. Multiple vent holes 231 are integrally formed on the cast refractory layer 23. The combustion air ducts 222 and the combustion chamber 24 are connected through the vent holes 231, and the exhaust gas passages 221 and the combustion chamber 24 are also connected through the vent holes 231.

[0042] Optionally, the central axis of the vent 231 forms an angle with the central axis of the combustion chamber 24, with the apex of the angle pointing towards the furnace cavity of the combustion furnace 1. The value of this angle ranges from 45° to 60°. When the angle is 60°, it facilitates better entry of exhaust gas and combustion air into the combustion chamber 24, resulting in better combustion performance.

[0043] Optionally, such as Figure 2 , 4 As shown in Figure 6, a flange 51 is welded to the end of the combustion air duct 25 away from the combustion shell 21, and a flange 51 is welded to the end of the exhaust gas duct 26 away from the combustion shell 21. The flanges 51 on the combustion air duct 25 and the exhaust gas duct 26 facilitate the fixed connection between the combustion mechanism 2 and the pipes for conveying exhaust gas and combustion air.

[0044] Optionally, such as Figure 3 , 4 As shown in Figure 6, a combustion mounting hole 211 is integrally formed on the end face of the combustion shell 21 away from the combustion furnace 1. A transition surface 232 is provided at the end of the cast refractory layer 23 near the combustion mounting hole 211, which can complete the transition between the diameter of the combustion mounting hole 211 and the diameter of the combustion chamber 24. A chamfer 233 is provided on the cast refractory layer 23, and the chamfer 233 is located at the combustion mounting hole 211.

[0045] like Figures 4-8As shown, the gas-assisted combustion mechanism 3 includes a gas casing 31, a gas pipe 32, an auxiliary combustion air duct 33, a gas distributor 34, a gas nozzle 35, an air distribution plate 36, and an air distribution duct 37. A flange 51 is welded to one end of the gas casing 31 near the combustion shell 21. Bolts are passed through the flange 51 of the gas casing 31, and the gas casing 31 is installed and fixed to the end of the combustion shell 21 away from the combustion furnace 1. Two auxiliary combustion air ducts are integrally formed inside the gas casing 31. One auxiliary combustion air duct is the first air duct 311, and the other is the second air duct 312. The first air duct 311 and the second air duct 312 are not connected; the first air duct 311 is located within the second air duct 312. Two auxiliary combustion air ducts 33 are welded to the outer surface of the gas casing 31. One auxiliary combustion air duct 33 is connected to the first air duct 311, and the other auxiliary combustion air duct 33 is connected to the second air duct 312. The end of the auxiliary combustion air duct 33 away from the gas casing 31 can be considered as an auxiliary combustion air outlet. A flange 51 is welded to the end of the combustion aid duct 33 away from the gas casing 31. The flange 51 on the combustion aid duct 33 facilitates the fixed connection between the combustion aid duct 33 and the air outlet of the blower. A combustion aid mounting hole 313 is integrally formed on the end face of the end of the gas casing 31 away from the combustion outer casing 21.

[0046] Optionally, such as Figure 4 , 8As shown in Figure 9, the gas distributor 34 is annular in shape, and a gas chamber 341 is integrally formed within it. The gas distributor 34 is installed on the side wall between the first air duct 311 and the second air duct 312 by welding or bonding, and is located within the first air duct 311. A through hole 342 is formed on the side of the gas distributor 34 facing the combustion shell 21; the through hole 342 is annular in shape. The gas nozzle 35 is tubular in shape, and multiple gas nozzle holes 351 are integrally formed within it. The multiple gas nozzle holes 351 are evenly distributed around the central axis of the gas nozzle 35, and the central axis of the gas nozzle holes 351 is parallel to the central axis of the gas nozzle 35. One end face of the gas nozzle 35 abuts against the side of the gas distributor 34 with the through hole 342, and they are connected by welding. Multiple gas injection holes 351 are connected to the gas chamber 341 through through holes 342. This multi-hole injection method facilitates rapid mixing of combustion air and gas, thus improving the combustion speed. The diameter of the gas injection hole 351 at the end near the gas distributor 34 is larger than the diameter at the end away from the gas distributor 34. The end of the gas nozzle 35 away from the gas distributor 34 enters the combustion chamber 24, located at the combustion mounting hole 211. The gas pipe 32 is fixedly connected to the gas housing 31 by welding. One end of the gas pipe 32 penetrates the shell wall of the gas housing 31 into the gas housing 31, and this end is fixedly connected to the gas distributor 34, communicating with the gas chamber 341. The end of the gas pipe 32 outside the gas housing 31 can be considered as the gas outlet. A flange 51 is welded to the end of the gas pipe 32 outside the gas housing 31, which facilitates the fixed connection between the gas pipe 32 and the gas delivery pipe.

[0047] like Figure 4 , 5 As shown in Figures 7, 8, and 9, the air distribution plate 36 is annular in shape, and multiple ventilation holes 361 are integrally formed on the air distribution plate 36, which are evenly distributed around the central axis of the air distribution plate 36. Multiple air distribution holes 371 are integrally formed on the air distribution duct 37, which are evenly distributed around the central axis of the air distribution duct 37. The outer wall of one end of the air distribution duct 37 abuts against the wall of the annular hole of the air distribution plate 36, and the air distribution duct 37 and the air distribution plate 36 are fixedly connected by welding. The air distribution duct 37 is located on the side of the air distribution plate 36 facing the combustion chamber 24. The air distribution plate 36 and the air distribution duct 37 are fitted onto the gas nozzle 35, and the gas nozzle 35 is located inside the air distribution duct 37. The air distribution plate 36 is located inside the second air duct 312, and the outer wall of the end of the air distribution duct 37 away from the air distribution plate 36 abuts against the side wall of the cast refractory layer 23 located at the combustion mounting hole 211.

[0048] like Figure 3 , 8As shown in Figures 10 and 11, the waste liquid injection and combustion mechanism 4 includes a sleeve 41, an inlet pipe 42, an outlet pipe 43, multiple waste liquid spray pipes 44, and a cyclone separator 45. A flange 51 is welded to the outer wall of the sleeve 41. This flange 51 is located at one end of the sleeve 41. Bolts are passed through the flange 51 of the sleeve 41, and the sleeve 41 is installed and fixed to the end of the gas casing 31 away from the combustion casing 21. The other end of the sleeve 41 passes through the combustion aid mounting hole 313 and the first air duct 311 of the gas casing 31 and enters the combustion chamber 24. The cyclone separator 45 is disposed on the outer wall of the other end of the sleeve 41. After the waste liquid injection and combustion mechanism 4 is installed and fixed with the gas combustion aid mechanism 3, the cyclone separator 45 is located at the gas nozzle 35. The cyclone separator 45 includes multiple... Figure 10 The blades 451 shown are evenly arranged around the central axis of the sleeve 41. The cyclone separator 45 can enhance the airflow within the first air duct 311.

[0049] like Figure 10 As shown, a cooling water cavity 411 is integrally formed inside the sleeve 41, and the cross-sectional shape of the cooling water cavity 411 is annular. The cooling water cavity 411 can prevent the flame of combustion exhaust gas and waste liquid from damaging the sleeve. A water inlet pipe 42 and a water outlet pipe 43 are welded to the outer surface of the sleeve 41, and both the water inlet pipe 42 and the water outlet pipe 43 are located outside the gas casing 31. The water inlet pipe 42 and the water outlet pipe 43 are connected to the cooling water cavity 411. The end of the water inlet pipe 42 away from the sleeve 41 can be regarded as the water inlet, and the end of the water outlet pipe 43 away from the sleeve 41 can be regarded as the water outlet. The water inlet pipe 42 is located below the sleeve 41, and the water outlet pipe 43 is located above the sleeve 41.

[0050] Optionally, such as Figure 10 As shown, a flange 51 is welded to the end of the inlet pipe 42 away from the sleeve 41, and a flange 51 is welded to the end of the outlet pipe 43 away from the sleeve 41. The flanges 51 on the inlet pipe 42 and the outlet pipe 43 facilitate the fixed connection between the inlet pipe 42 and the water supply pipe of the water pump, and the fixed connection between the outlet pipe 43 and the drain pipe.

[0051] like Figure 10As shown, the end of the sleeve 41 located outside the gas casing 31 is sealed. Multiple waste liquid nozzles 44 are mounted on the sleeve 41, and are evenly distributed around the central axis of the sleeve 41. This allows multiple waste liquid nozzles 44 to simultaneously spray various different waste liquids. Since the connection method between the multiple waste liquid nozzles 44 and the sleeve 41 is the same, the connection method of one waste liquid nozzle 44 to the sleeve 41 is described as an example. One end of the waste liquid nozzle 44 passes through the sealed end of the sleeve 41 and the cylinder cavity 412 of the sleeve 41 into the combustion chamber 24. The other end of the waste liquid nozzle 44 is sealed and located outside the sleeve 41. A waste liquid pipe 46 and an atomizing pipe 47 are welded to the outer surface of the waste liquid nozzle 44. Both the waste liquid pipe 46 and the atomizing pipe 47 are located at the end of the waste liquid nozzle 44 exposed outside the sleeve 41. The waste liquid pipe 46 is connected to the space inside the waste liquid spray pipe 44, and the atomizing pipe 47 is also connected to the space inside the waste liquid spray pipe 44. The end of the waste liquid pipe 46 furthest from the waste liquid spray pipe 44 can be considered as the waste liquid interface, and the end of the atomizing pipe 47 furthest from the waste liquid spray pipe 44 can be considered as the atomizing interface. The atomizing pipe 47 is located to the right of the waste liquid pipe 46.

[0052] like Figure 3 , 10 As shown in Figure 12, the high-efficiency burner also includes an igniter 52. An ignition tube 53 is welded to the end face of the flange 51 of the sleeve 41, away from the gas casing 31. A gap 54 exists between the gas nozzle 35 in the first air duct 311 and the cyclone separator 45 on the sleeve 41. One end of the ignition tube 53 passes through the flange 51 and through the gap 54 into the combustion chamber 24, located at the combustion mounting hole 211. The end of the ignition tube 53 located at the combustion mounting hole 211 is positioned within the cavity of the gas nozzle 35. An igniter 52 is installed on the end of the ignition tube 53 exposed outside the combustion chamber 24. The igniter 52 is used to ignite the gas ejected from the combustion nozzle. For example, the igniter 52 can be a model XLGND-03J igniter sold by Shaanxi Xinlv High Energy Environmental Protection Equipment Co., Ltd.

[0053] like Figure 5 , 6 As shown, the high-efficiency burner also includes three flame detectors 55. For example, the flame detectors 55 can be the integrated ultraviolet flame detector 55, model XLZJ-102AT, sold by Shaanxi Xinlv High-Energy Environmental Protection Equipment Co., Ltd. Among them, as... Figure 5As shown, one flame detector 55 is installed in the waste liquid combustion mechanism 4, and two other flame detectors 55 are installed in the combustion mechanism 2. A flame detection tube 56 is welded to the flange 51 of the sleeve 41. One end of the flame detection tube 56 is connected to the first air duct 311 inside the gas casing 31, and the other end of the flame detection tube 56 is connected to the flame detector 55. The flame detector 55 detects whether there is a flame in the first air duct 311. Figure 6 As shown, two flame detection tubes 56 are provided on the combustion shell 21, and these two flame detection tubes 56 are respectively located on both sides of the combustion mounting hole 211. Since the two flame detection tubes 56 are connected to the combustion shell 21 in the same way, the connection method of one of the flame detection tubes 56 to the combustion shell 21 is described as an example. The flame detection tube 56 is welded to the end face of the combustion shell 21 where the combustion mounting hole 211 is provided. One end of the flame detection tube 56 penetrates the combustion shell 21 into a vent hole 231 of the cast refractory layer 23. The other end of the flame detection tube 56 is connected to the flame detector 55 to facilitate the monitoring of the flame in the combustion chamber 24 through the flame detector 55.

[0054] The operation process of a high-efficiency burner according to an exemplary embodiment:

[0055] like Figures 1 to 14 As shown, the combustion mechanism 2 of the high-efficiency burner is installed and fixed to the combustion furnace 1, so as to achieve the purpose of installing the high-efficiency burner in the combustion furnace 1. Figure 3 The shape formed by the combination of the two arc-shaped dotted lines can be considered as the flame within the combustion chamber 24. After the high-efficiency burner is installed in the combustion furnace 1, the space between the combustion chamber 24 and the connecting pipe 11 forms a new combustion chamber, which includes three sub-chambers, such as... Figure 3 As shown, the three combustion chambers are heating chamber 61, weak oxygen combustion chamber 62, and aerobic combustion chamber 63.

[0056] First, natural gas is supplied. The gas flows through gas pipe 32, sequentially through the gas chamber 341 of gas distribution component 34, and the gas nozzle 351 of gas nozzle 35. It is then injected into heating chamber 61 through gas nozzle 351. Afterward, igniter 52 ignites the gas through ignition tube 53 to form a combustion flame. Waste liquid to be incinerated flows into waste liquid nozzle 44 through waste liquid pipe 46. Compressed air ejected from atomizing pipe 47 atomizes the waste liquid in waste liquid nozzle 44. The atomized waste liquid is then injected into combustion chamber 24 from one end of waste liquid nozzle 44 for incineration.

[0057] The first air supply enters the first air duct 311 through the combustion aid duct 33, passes through the cyclone separator 45, and is ejected in front of the gas nozzle 35. Part of the first air supply assists in the combustion of the gas; another part of the first air supply moves along the sleeve 41 and rapidly heats up during the movement, providing combustion aid for the waste liquid ejected from the waste liquid nozzle 44, thus having the function of assisting in atomization and rectification of the waste liquid. The second air supply enters the second air duct 312 through the combustion aid duct 33. The second air supply first passes through the vent holes 361 of the air distribution plate 36 to make the airflow uniform, and then is ejected in front of the gas nozzle 35 through the air distribution holes 371 of the air distribution duct 37. The second air supply can quickly mix with the gas. This arrangement can improve combustion efficiency and enhance the stability of flame combustion. The heating chamber 61 utilizes the combustion of fuel gas to ensure a high temperature inside the chamber, and this area is rich in oxygen, so the atomized waste liquid can be quickly ignited and burned, thereby increasing the combustion rate and heating rate of the waste liquid, which is conducive to the rapid oxidation of harmful substances.

[0058] When multiple waste gases need to be incinerated, several waste gases with similar properties are first connected to multiple waste gas pipes 26 of the same waste gas channel 221. Then, several waste gases with different properties are connected to waste gas pipes of different waste gas channels 221. The excess waste gas pipes 26 on the multiple waste gas channels 221 are sealed. Afterward, the waste gases can enter the combustion chamber 24 through the vent holes 231 of the cast refractory layer 23. This arrangement allows the high-efficiency burner to simultaneously incinerate multiple waste gases with different properties. The oxygen supply required for combustion in the weak oxygen combustion chamber 62 is insufficient, and the flame intensity is low, thus lacking the conditions for the formation of nitrogen oxides, which can inhibit the generation of nitrogen oxides, especially the combustion of nitrogen-containing organic matter. The aerobic combustion chamber 63 contains less combustion air, which is beneficial for the incineration of organic components in waste gases and waste liquids.

[0059] This unique design with three combustion chambers enables the high-efficiency burner to accelerate the combustion rate of waste gas and waste liquid, achieve rapid heating, and reach high combustion temperatures. It can incinerate chlorine- and fluorine-containing organic waste liquids and gases with a high incineration removal rate and inhibits the formation of dioxins. Simultaneously, it easily reduces the oxygen content within the weak oxygen combustion chamber 62, suppressing the formation of nitrogen oxides.

[0060] 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 within the protection scope of the present invention.
