Description

Technical Field

[0001] The utility model relates to a burner, in particular to a wide-load adjustable acid gas burner, belonging to the technical field of sulfur recovery and combustion. Background Art

[0002] Widely load-adjustable acid gas burners are a special type of burner primarily used to treat acid gases, such as hydrogen sulfide (H2S). Designed to maintain stable combustion performance over a wide load range and adjustable according to actual needs, these burners are widely used in the petroleum, chemical, and natural gas industries to treat waste gases containing acid gases and convert them into harmless substances. In refineries, acid gas burners can be used to treat hydrogen sulfide generated during the desulfurization process, converting it into sulfur dioxide, which can then be further processed into sulfuric acid or other useful chemicals.

[0003] During actual operation, acid gas burners can experience uneven mixing of acid gas and air, affecting flame stability. The throat velocity can be too low, leading to flashback near the throat, where the acid gas burns within the throat. This can cause high-temperature erosion of the burner tip, burner throat, acid gas lance, and swirler, seriously impacting the long-term stable operation of the burner and the entire device. To address this, we offer a wide-load adjustable acid gas burner to address these issues. Utility Model Content

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] See also Figures 1-5 A wide load adjustable acid gas burner includes a shell 1, an acid gas lance 2 and an acid gas burner throat 3. One side of the shell 1 is connected to an external air inlet pipe 4, through which external air is introduced into the shell 1. A flange 5 is installed at the top of the shell 1. The inner wall of the flange 5 is connected to an acid gas outer pipe 6. The acid gas outer pipe 6 is fixed by the flange 5 to maintain the stability of the acid gas outer pipe 6. One side of the acid gas outer pipe 6 is connected to an acid gas inlet pipe 7. Acid gas is introduced into the acid gas outer pipe 6 through the acid gas inlet pipe 7. The acid gas is transmitted through the acid gas outer pipe 6 and discharged into the burner.

[0022] The acid gas spray gun 2 is installed inside the acid gas outer tube 6, and the acid gas burner throat 3 is arranged inside the shell 1. The acid gas burner throat 3 includes components such as a gun body, a nozzle, a width adjustment nut and a clamping sleeve. The nozzle is used to spray acid gas, and the width adjustment nut and clamping sleeve are used to adjust the opening size of the nozzle, thereby controlling the gas injection amount and injection range, and playing a control function on the nozzle.

[0023] The inner wall of the shell 1 is provided with a heat insulation lining 8, which reduces the heat transfer of the heat insulation lining 8 to the outside, so as to prevent the shell 1 from being heated. The inner wall of the heat insulation lining 8 is connected with a heat-resistant lining 9, which blocks the high temperature inside to prevent the high temperature from radiating to the outside and causing damage to other components. The cavity inside the heat-resistant lining 9 forms a combustion chamber, so that the flame burns inside. The upper surface of the heat insulation lining 8 and the heat-resistant lining 9 is connected with a partition plate 10. The upper surface of the partition plate 10 is connected with an inner shell 11, which is supported by the partition plate 10 and the cyclone 13 to maintain its stability. The inner side of the inner shell 11 is provided with a plurality of air vents 12 in a circular array. The air vents 12 disperse the air introduced by the air inlet pipe into the inner shell 11. The upper surface of the partition plate 10 is connected with a cyclone 13, which is located inside the inner shell 11. The cyclone 13 guides the air dispersed into the inner shell 11 to change the direction of air flow, so that the air rotates and mixes with the acid gas. The upper surface of the cyclone 13 is connected with a cyclone cylinder 14, which wraps the air and acid gas inside for sufficient mixing.

[0024] One end of the acid gas burner throat 3 is connected to one side of the cyclone 13, and the acid gas burner throat 3 is located outside the acid gas lance 2. The acid gas burner throat 3 is used to control the airflow and mixing conditions during combustion, improve the stability of flame combustion, and thus improve the combustion efficiency and reduce the generation of pollutants.

[0025] The inner wall of the shell 1 is connected with a plurality of sight hole sleeves 15, which are located inside the shell 1 and inside the heat-resistant lining 9. The sight hole sleeves 15 are used to observe the state and color of the flame in the combustion chamber, judge the temperature and combustion of the flame, and obtain the combustion information of the flame. The end of the sight hole sleeve 15 inside the heat-resistant lining 9 is externally sleeved with an aluminum silicate blanket 16, which protects the sight hole sleeve 15 from high temperature damage, improves the safety of the sight hole sleeve 15 and prolongs the service life.

[0026] The outer surface of each of the plurality of sight hole sleeves 15 is connected with a cooling air pipe 17, which is located outside the shell 1. The cooling air pipe 17 introduces cooling air into the sight hole sleeve 15 to ensure the safety and reliability of the sight hole sleeve 15.

[0027] The inner wall of the shell 1 is connected with a plurality of cooling port connecting pipes 18, and the plurality of cooling port connecting pipes 18 are in communication with the inside of the shell 1. The acid gas burner generates high temperature. If the temperature is not lowered in time, the temperature of the combustion chamber may be too high, thereby affecting the performance and service life of the acid gas lance 2 and the throat 3 of the acid gas burner and even causing a safety accident. The cooling port connecting pipes 18 are used for lowering the temperature of the combustion chamber and the inside of the shell 1, so that the temperature of the components in the combustion chamber and the inside of the shell 1 is not too high. The cooling port connecting pipes 18 can introduce cooling medium to cool the components in the combustion chamber and the inside of the shell 1, so that the temperature of the components in the combustion chamber and the inside of the shell 1 is controlled within a safe range, and the acid gas burner is ensured to run stably.

[0028] The inner wall of the flange 5 is connected with a long-lasting lamp seat sleeve 19. One end of the long-lasting lamp seat sleeve 19 located in the inside of the shell 1 is connected with a long-lasting lamp support ring 20. The long-lasting lamp seat sleeve 19 protects the flame of the long-lasting lamp, so that the flame of the long-lasting lamp is kept stable and combustion, and the safe operation of the long-lasting lamp is improved.

[0029] In use, first, external air enters the inside of the shell 1 through the external air inlet connecting pipe 4, then uniformly enters the inside of the cyclone 13 through the air holes 12 in the inner shell 11, and is guided to rotate by the cyclone 13. At the same time, acid gas enters the acid gas outer pipe 6 through the acid gas inlet connecting pipe 7, then is compressed and sprayed by the acid gas lance 2, and the sprayed acid gas is fully mixed with the rotating air. The flame of the sprayed acid gas is burned in the heat-resistant lining 9 after the acid gas is ignited.
