Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of combustion equipment, and particularly relates to a dual-exhaust gas fuel ring. Background Art
[0002] With the acceleration of the industrialization process, a large amount of chemical waste gas has been generated in various industrial production activities such as the chemical industry, electroplating, papermaking, printing and dyeing, and pharmaceutical industries. The composition of chemical waste gas is complex and contains a large number of harmful substances, such as organic pollutants like benzene, toluene, and xylene, as well as heavy metal pollutants like mercury, lead, and cadmium. After entering the human body through respiration, these substances will damage the human respiratory system, nervous system, cardiovascular system, etc., causing various diseases such as respiratory diseases, cancer, and nervous system disorders. At the same time, pollutants such as sulfur dioxide and nitrogen oxides in chemical waste gas will form acid rain, causing serious damage to soil, water bodies, and vegetation, leading to problems such as soil acidification, water body eutrophication, and damage to forest vegetation. In addition, volatile organic compounds (VOCs) and nitrogen oxides in chemical waste gas will also undergo photochemical reactions in the atmosphere to generate secondary pollutants such as ozone, forming photochemical smog, affecting atmospheric visibility, and posing a threat to the balance and stability of the ecosystem.
[0003] In the prior art, when dealing with chemical waste gas, problems such as relatively high waste gas calorific value and relatively large flow rate are often encountered. Most of the treatment methods are to burn it off with a high-altitude flare, but the phenomenon of incomplete combustion often occurs, resulting in the emission of harmful gas-containing air. And currently, there are many types of chemical waste gas, and it is very difficult to treat them in multiple aspects simultaneously, greatly increasing the difficulty of waste gas treatment, and there is a need for improvement. Summary of the Invention
[0004] The purpose of the present invention is to provide a dual-exhaust gas fuel ring, and its advantage is good waste gas treatment effect and reduced energy waste.
[0005] The above technical purpose of the present invention is achieved through the following technical solutions: A dual-exhaust gas fuel ring includes a fuel ring and a partition fixedly connected inside the fuel ring for separating the inside of the fuel ring into a first exhaust gas chamber and a second exhaust gas chamber. A first exhaust gas inlet pipe and a second exhaust gas inlet pipe for inputting exhaust gas are respectively fixedly connected inside the first exhaust gas chamber and the second exhaust gas chamber. A number of first exhaust gas intervention nozzles and second exhaust gas intervention nozzles that are arranged in an interlaced manner along the circumferential direction are fixedly connected to the first exhaust gas chamber and the second exhaust gas chamber.
[0006] The present invention is further configured such that: on the first exhaust gas inlet pipe and the second exhaust gas inlet pipe, an extended inlet pipe extending into the first exhaust gas chamber and the second exhaust gas chamber is fixedly connected coaxially. The center line of the extended inlet pipe intersects and is perpendicular to the center line of the fuel ring. The length of the extended inlet pipe is not less than 1 / 2 of the ring diameter of the fuel ring and not more than 3 / 4 of the ring diameter of the fuel ring.
[0007] The present invention is further configured such that: both the first exhaust gas injection nozzle and the second exhaust gas injection nozzle include an exhaust gas ejection part fixedly connected to the outside of the fuel ring for ejecting exhaust gas and an exhaust gas inlet part fixedly connected to the inside of the fuel ring. The exhaust gas inlet part and the exhaust gas ejection part are connected based on a bent part. On the exhaust gas inlet part, a sliding inlet pipe for exhaust gas to enter is slidably connected coaxially based on a locking and adjusting assembly.
[0008] The present invention is further configured such that: the exhaust gas inlet part is arranged in the fuel ring in an inclined direction or a vertical direction relative to the center line of the fuel ring. The vertical distance between the pipe orifice of the sliding inlet pipe and the inner wall of the fuel ring is greater than 1 / 2 of the ring diameter of the fuel ring and less than the ring diameter of the fuel ring.
[0009] The present invention is further configured such that: the locking and adjusting assembly includes at least one locking and adjusting hole opened on the exhaust gas inlet part and a pressing screw rotatably connected to the locking and adjusting hole for pressing and fixing the sliding inlet pipe on the exhaust gas inlet part.
[0010] The present invention is further configured such that: the bent part is made of a tin metal pipe. The exhaust gas ejection part and the exhaust gas inlet part are made of a copper pipe or an aluminum pipe and are respectively welded to both ends of the bent part. When it is necessary to adjust the angle of exhaust gas ejection, the tin metal pipe is heated to 200 - 220 degrees Celsius to soften and bend the tin metal pipe.
[0011] The present invention is further configured such that: both ends of the fuel ring along the direction of combustion-supporting gas delivery are fixedly connected with a burner docking flange and a combustion furnace docking flange respectively based on a locking assembly. The front end of the fuel ring is connected to a burner, and the rear end is connected to a combustion furnace. The combustion-supporting gas passes through the fuel ring from the burner and enters the combustion furnace. Before entering the combustion furnace, the combustion-supporting gas is fully mixed with the exhaust gas so that the combustible components in the combustion-supporting gas and the exhaust gas are fully burned.
[0012] The present invention is further configured such that: the locking assembly includes locking rings coaxially and fixedly connected to both ends of the fuel ring, and a plurality of first locking threaded holes uniformly formed on the locking rings along the circumferential direction. A plurality of second locking threaded holes mating with the first locking threaded holes are formed on the burner docking flange and the combustion furnace docking flange.

At the same time, a plurality of first waste gas intervention nozzles and second waste gas intervention nozzles are arranged along the circumferential direction and staggered on the first waste gas chamber and the second waste gas chamber. The two waste gases respectively enter the first waste gas chamber and the second waste gas chamber and are respectively ejected from the first waste gas intervention nozzles and the second waste gas intervention nozzles, so that the two waste gases and the combustion-supporting gas can be fully and evenly mixed before entering the combustion furnace, thus avoiding the situation of incomplete local combustion or unstable flame, improving the combustion efficiency, reducing energy waste. At the same time, by controlling the flow rate, pressure and types of the two waste gases entering the first waste gas chamber and the second waste gas chamber, the reaction conditions such as the temperature, concentration and mixing ratio of the waste gas and the combustion-supporting gas after mixing can be flexibly adjusted, so that the combustible components in the combustion-supporting gas and the waste gas can be fully burned, thereby effectively improving the mixing efficiency and the stability of combustion, and reducing the generation and emission of pollutants such as carbon monoxide and nitrogen oxides; 2. Extension inlet pipes are coaxially arranged on the first waste gas inlet pipe and the second waste gas inlet pipe, and a sliding inlet pipe is arranged on the waste gas inlet pipes of the first waste gas intervention nozzles and the second waste gas intervention nozzles based on a locking and adjusting assembly. By making the distance between the sliding inlet pipe and the inner wall of the fuel ring greater than the distance between the extension inlet pipe and the inner wall of the fuel ring, when the waste gas enters the waste gas chamber from the extension inlet pipe, it accumulates at the bottom of the waste gas chamber and diffuses to the top of the waste gas chamber, and finally is discharged from the sliding inlet pipe, so that the waste gas can be evenly ejected from a plurality of first waste gas intervention nozzles and second waste gas intervention nozzles, improving the mixing uniformity of the waste gas and the combustion-supporting gas. At the same time, the position of the sliding inlet pipe can be flexibly adjusted through the locking and adjusting assembly to adapt to the combustion requirements of different types of waste gases.

Detailed implementation mode
[0017] The present invention will be further described in detail below with reference to the accompanying drawings.
[0018] Embodiment: Referring to Figures 1 to 3 , a dual-exhaust gas fuel ring includes a fuel ring 1 and a partition plate 2 fixedly connected inside the fuel ring 1 for dividing the inside of the fuel ring 1 into a first exhaust gas chamber 11 and a second exhaust gas chamber 12. A first exhaust gas inlet pipe 3 and a second exhaust gas inlet pipe 4 for inputting exhaust gas are respectively fixedly connected in the first exhaust gas chamber 11 and the second exhaust gas chamber 12. A number of first exhaust gas intervention nozzles 5 and second exhaust gas intervention nozzles 6 are fixedly connected along the circumferential direction on the first exhaust gas chamber 11 and the second exhaust gas chamber 12 and are arranged in an interleaved manner. The two kinds of exhaust gases respectively enter the exhaust gas chambers from the exhaust gas inlet pipes and finally are discharged from the exhaust gas intervention nozzles along the circumferential direction, and are mixed with the combustion-supporting gas passing through the fuel ring 1, and finally enter the combustion furnace for full combustion. The two kinds of exhaust gases respectively enter the first exhaust gas chamber 11 and the second exhaust gas chamber 12 and are respectively ejected from the first exhaust gas intervention nozzle 5 and the second exhaust gas intervention nozzle 6, so that the two kinds of exhaust gases and the combustion-supporting gas can be fully and evenly mixed before entering the combustion furnace, thereby avoiding the situation of incomplete local combustion or unstable flame, improving the combustion efficiency, reducing energy waste, and at the same time, by controlling the flow rate, pressure and types of the two kinds of exhaust gases entering the first exhaust gas chamber 11 and the second exhaust gas chamber 12, the reaction conditions such as the temperature, concentration and mixing ratio of the exhaust gas and the combustion-supporting gas after mixing can be flexibly adjusted, so that the combustible components in the combustion-supporting gas and the exhaust gas can be fully burned, thereby effectively improving the mixing efficiency and the stability of combustion, and reducing the generation and emission of pollutants such as carbon monoxide and nitrogen oxides.
[0019] Referring to Figure 1, specifically, on the first exhaust gas inlet pipe 3 and the second exhaust gas inlet pipe 4, an extended inlet pipe 7 extending into the first exhaust gas chamber 11 and the second exhaust gas chamber 12 is fixedly connected coaxially. The center line of the extended inlet pipe 7 intersects and is perpendicular to the center line of the fuel ring 1. The length of the extended inlet pipe 7 is not less than 1 / 2 of the ring diameter of the fuel ring 1 and not more than 3 / 4 of the ring diameter of the fuel ring 1.
[0020] Reference Figures 1 to 2 , specifically, the first exhaust gas injection nozzle 5 and the second exhaust gas injection nozzle 6 both include an exhaust gas ejection part 51 fixedly connected to the outside of the fuel ring 1 for ejecting exhaust gas and an exhaust gas inlet part 52 fixedly connected to the inside of the fuel ring 1. The exhaust gas inlet part 52 and the exhaust gas ejection part 51 are connected based on a bent part 53. On the exhaust gas inlet part 52, a sliding inlet pipe 55 for the exhaust gas to enter is coaxially slidably connected based on a locking and adjusting component 54. The exhaust gas inlet part 52 is arranged in the fuel ring 1 in an inclined direction or a vertical direction relative to the center line of the fuel ring 1. The vertical distance between the pipe orifice of the sliding inlet pipe 55 and the inner wall of the fuel ring 1 is greater than 1 / 2 of the ring diameter of the fuel ring 1 and less than the ring diameter of the fuel ring 1. By making the distance between the sliding inlet pipe 55 and the inner wall of the fuel ring 1 greater than the distance between the extended inlet pipe 7 and the inner wall of the fuel ring 1, when the exhaust gas enters the exhaust gas chamber from the extended inlet pipe 7, it accumulates at the bottom of the exhaust gas chamber and diffuses to the top of the exhaust gas chamber, and finally discharges from the sliding inlet pipe 55, so that the exhaust gas can be evenly ejected from a number of the first exhaust gas injection nozzles 5 and the second exhaust gas injection nozzles 6, improving the mixing uniformity of the exhaust gas and the combustion-supporting gas. The locking and adjusting component 54 includes at least one locking and adjusting hole 541 opened on the exhaust gas inlet part 52 and a pressing screw 542 rotatably connected to the locking and adjusting hole 541 for pressing and fixing the sliding inlet pipe 55 on the exhaust gas inlet part 52. When it is necessary to adjust the distance between the sliding inlet pipe 55 and the inner wall of the fuel ring 1, by loosening the pressing screw 542, the sliding inlet pipe 55 can be slidably adjusted in the exhaust gas inlet part 52, and after the adjustment is completed, the pressing screw 542 is tightened to achieve locking, realizing flexible adjustment of the position of the sliding inlet pipe 55 to adapt to different types of exhaust gas combustion requirements. The bent part 53 is made of a tin metal pipe, and the exhaust gas ejection part 51 and the exhaust gas inlet part 52 are made of a copper pipe or an aluminum pipe and are respectively welded to both ends of the bent part 53. When it is necessary to adjust the ejection angle of the exhaust gas, the tin metal pipe is heated to 200 - 220 degrees Celsius to soften and bend the tin metal pipe, so as to flexibly adjust the ejection angle of the exhaust gas ejection part 51 and improve the mixing effect of the exhaust gas and the combustion-supporting gas.
[0021] Reference Figure 1 and Figure 3, Specifically, both ends of the fuel ring 1 along the direction of the combustion-supporting gas transportation are fixedly connected to a burner docking flange 9 and a combustion furnace docking flange 10 respectively based on a locking assembly 8. The front end of the fuel ring 1 is connected to the burner, and the rear end is connected to the combustion furnace. The combustion-supporting gas passes through the fuel ring 1 from the burner and enters the combustion furnace. Before entering the combustion furnace, the combustion-supporting gas is fully mixed with the exhaust gas so that the combustible components in the combustion-supporting gas and the exhaust gas are fully burned. The locking assembly 8 includes locking rings 81 coaxially and fixedly connected to both ends of the fuel ring 1 and a number of first locking threaded holes 82 evenly opened on the locking rings 81 along the circumferential direction. A number of second locking threaded holes 83 matching the first locking threaded holes 82 are opened on the burner docking flange 9 and the combustion furnace docking flange 10. The first locking threaded holes 82 and the second locking threaded holes 83 are locked and fixed based on locking bolts 84. A sealing groove 85 is coaxially opened on the locking ring 81, and a sealing gasket 86 for ensuring the sealing performance is arranged in the sealing groove 85. The locking assembly 8 is used to quickly disassemble the fuel ring 1 from the burner docking flange 9 and the combustion furnace docking flange 10 so as to adjust the position of the sliding intake pipe 55 or clean the inner wall of the exhaust gas cavity, preventing particulate impurities in the exhaust gas from adsorbing on the inner wall of the exhaust gas cavity and causing pipeline blockage, which affects the normal discharge of the exhaust gas.
[0022] Brief description of the working principle: By controlling the flow rate, pressure, and types of the two exhaust gases entering the first exhaust gas cavity 11 and the second exhaust gas cavity 12, the reaction conditions such as the temperature, concentration, and mixing ratio after the exhaust gas and the combustion-supporting gas are mixed can be flexibly adjusted, so that the combustible components in the combustion-supporting gas and the exhaust gas are fully burned.

After reading this specification, those skilled in the art can make modifications with creative contributions to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
