Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, specifically to a boiler burner for treating yellow phosphorus tail gas. Background Technology

[0002] For example, a special burner for burning yellow phosphorus tail gas, as disclosed in patent publication number CN204880157U, includes a circular baffle, a main body, an ignition gun, a gas passage, and an air supply passage. This allows for complete combustion of the yellow phosphorus tail gas within the furnace. Through proper air distribution, it not only increases the combustion temperature in the furnace and enhances heat exchange efficiency, but also controls the oxygen content after flue gas combustion. Furthermore, it inhibits the formation of acidic substances, prevents dew point corrosion, and extends the boiler's service life. This improves the thermal energy utilization rate of the yellow phosphorus tail gas.

[0003] However, during the use of the above-mentioned equipment, although the combustion reaction kinetic rate of yellow phosphorus tail gas is fast, the overall energy density of low-calorific-value tail gas is low. The flame is prone to extinguishing or backfire due to insufficient heat. If the fuel and air are not mixed sufficiently, a fuel-rich zone will be formed in a local area, resulting in incomplete combustion of CO and reduced thermal efficiency. Therefore, we propose a more convenient and practical boiler burner to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide a boiler burner for treating yellow phosphorus tail gas, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a boiler burner for treating yellow phosphorus tail gas, comprising a boiler body, a support frame fixedly connected to one side of the bottom of the boiler body, a chimney fixedly connected to one side of the top of the boiler body, a supplementary combustion mechanism provided on one side of the boiler body, a main combustion mechanism provided on one side of the supplementary combustion mechanism, the main combustion mechanism including a main combustion cylinder, a second sealing ring installed on one side of the main combustion cylinder, a mixing cylinder fixedly connected to one side of the second sealing ring, a plurality of equidistant ignition needles installed on one side of the mixing cylinder, a through hole opened on one side of the mixing cylinder, an acetylene inlet pipe fixedly connected in the through hole, and mixing components provided on both sides of the mixing cylinder.

[0006] Furthermore, the combustion supplementation mechanism includes a combustion supplementation cylinder, with first sealing rings installed on both sides of the combustion supplementation cylinder. The combustion supplementation cylinder is connected to the boiler body, and the bottom of the combustion supplementation cylinder is in contact with the support frame.

[0007] Furthermore, a through hole is provided in the center of the bottom of the combustion cylinder, and a first air pipe is fixedly connected inside the through hole. A first solenoid valve and a first temperature gauge are installed sequentially on the outer wall of the first air pipe.

[0008] Furthermore, a through hole is provided in the center of the bottom of the main combustion cylinder, and a second air pipe is fixedly connected inside the through hole. A second solenoid valve and a second thermometer are installed sequentially on the outer wall of the second air pipe.

[0009] Furthermore, the mixing component includes symmetrically arranged connecting pipes connected to the mixing cylinder, with a filter box fixedly connected to one end of the connecting pipe and a flow equalization plate fixedly connected to the inner wall of one end of the connecting pipe.

[0010] Furthermore, filter plates are fixedly connected to the inner walls on both sides of the filter box, and a yellow phosphorus exhaust gas inlet pipe is fixedly connected to one side of the filter box. A swirl vane is installed on the inner wall of one end of the yellow phosphorus exhaust gas inlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This boiler burner for treating yellow phosphorus tail gas, through the setting of a supplementary combustion mechanism and a main combustion mechanism, fixes the main combustion cylinder, the second sealing ring, and the supplementary combustion cylinder during operation. When yellow phosphorus tail gas is input into the mixing cylinder through the yellow phosphorus tail gas inlet pipe, the yellow phosphorus tail gas forms a vortex flow with the primary air through the swirl vanes. Then, the yellow phosphorus tail gas is filtered through the filter box and filter plate. At the same time, under the action of the flow equalization plate, the yellow phosphorus tail gas is input into the mixing cylinder. Acetylene is input into the mixing cylinder through the acetylene inlet pipe and ignited by the ignition needle. Finally, the second solenoid valve opens to allow air to be input into the main combustion cylinder through the second air pipe for combustion, and the second temperature gauge monitors the process. This device can ensure that the yellow phosphorus tail gas and air are fully mixed before entering the main combustion cylinder, avoiding local oxygen deficiency or fuel richness, thereby enabling more complete combustion of the yellow phosphorus tail gas, improving combustion efficiency, reducing pollutant emissions, and making it highly practical and suitable for widespread application.

[0013] Meanwhile, the afterburning mechanism can precisely control the airflow into the afterburning cylinder, and adjust the air supply in real time according to the amount of yellow phosphorus tail gas and combustion requirements, so that the yellow phosphorus tail gas and air can be fully mixed and the combustion efficiency can be improved.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] During boiler operation, a burner is required. The burner provided by this utility model is specifically designed for use inside boilers. Before using the burner, a comprehensive inspection of the equipment should be conducted to ensure that all components are intact, connections are tight, and there are no leaks. When using yellow phosphorus tail gas as fuel, its quality should be ensured to be stable, free of impurities and harmful substances. During combustion, the air supply should be adjusted as needed to control the oxygen content during combustion. Too much air will lead to heat loss, while too little air will lead to incomplete combustion and the production of harmful gases. The temperature inside the combustion chamber should be monitored in real time using a thermometer to adjust the combustion state in a timely manner and prevent damage to the equipment or impact on combustion efficiency due to excessively high or low temperatures.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a boiler burner for treating yellow phosphorus tail gas, including a boiler body 1, a support frame 2 fixedly connected to one side of the bottom of the boiler body 1, a chimney 3 fixedly connected to one side of the top of the boiler body 1, a supplementary combustion mechanism 4 provided on one side of the boiler body 1, a main combustion mechanism 5 provided on one side of the supplementary combustion mechanism 4, the main combustion mechanism 5 including a main combustion cylinder 501, a second sealing ring 505 installed on one side of the main combustion cylinder 501, a mixing cylinder 506 fixedly connected to one side of the second sealing ring 505, a plurality of equidistant ignition needles 507 installed on one side of the mixing cylinder 506, a through hole opened on one side of the mixing cylinder 506, an acetylene inlet pipe 508 fixedly connected in the through hole, and mixing components provided on both sides of the mixing cylinder 506.

[0022] like Figure 2As shown, the combustion supplementation mechanism 4 includes a combustion supplementation cylinder 401. First sealing rings 402 are installed on both sides of the combustion supplementation cylinder 401. The combustion supplementation cylinder 401 is connected to the boiler body 1. The bottom of the combustion supplementation cylinder 401 is attached to the support frame 2. A through hole is opened in the center of the bottom of the combustion supplementation cylinder 401. A first air pipe 403 is fixedly connected in the through hole. A first solenoid valve 404 and a first thermometer 405 are installed sequentially on the outer wall of the first air pipe 403.

[0023] It should be noted that during use, the combustion chamber 401 and the first sealing ring 402 are first fixed to the boiler body 1 using bolts and other connecting parts. At the same time, the first temperature gauge 405 monitors the temperature inside the combustion chamber 401. When the temperature is abnormal, the first solenoid valve 404 opens to allow air to be input into the combustion chamber 401 through the first air pipe 403 for combustion. The combustion mechanism 4 can precisely control the air flow rate entering the combustion chamber 401. According to the amount of yellow phosphorus tail gas and combustion requirements, the air supply is adjusted in real time to ensure that the yellow phosphorus tail gas and air can be fully mixed to improve combustion efficiency.

[0024] like Figures 3-4 As shown, a through hole is provided in the center of the bottom of the main combustion cylinder 501. A second air pipe 502 is fixedly connected in the through hole. A second solenoid valve 503 and a second thermometer 504 are installed sequentially on the outer wall of the second air pipe 502. The mixing assembly includes symmetrically arranged connecting pipes 509. The connecting pipes 509 and the mixing cylinder 506 are connected. A filter box 510 is fixedly connected to one end of the connecting pipe 509. A flow equalization plate 511 is fixedly connected to the inner wall of one end of the connecting pipe 509. Filter plates 512 are fixedly connected to the inner walls of both sides of the filter box 510. A yellow phosphorus tail gas inlet pipe 513 is fixedly connected to one side of the filter box 510. A swirl vane 514 is installed on the inner wall of one end of the yellow phosphorus tail gas inlet pipe 513.

[0025] It should be noted that during use, there are two mixing components: one for inputting yellow phosphorus tail gas and the other for inputting coal gas. The main combustion chamber 501, the second sealing ring 505, and the supplementary combustion chamber 401 are fixed in place. When yellow phosphorus tail gas is input into the mixing chamber 506 through the yellow phosphorus tail gas inlet pipe 513, the yellow phosphorus tail gas is vortexed by the swirl vanes 514, causing it to flow in a vortex with the primary air. Then, the yellow phosphorus tail gas is filtered through the filter box 510 and the filter plate 512, while simultaneously being filtered by the flow equalization plate 511. Under the action of the mechanism, the yellow phosphorus tail gas is input into the mixing cylinder 506, and acetylene is input into the mixing cylinder 506 through the acetylene inlet pipe 508 and ignited by the ignition needle 507. Finally, the second solenoid valve 503 is opened to allow air to be input into the main combustion cylinder 501 through the second air pipe 502 for combustion, and the second temperature gauge 504 is used for monitoring. When the main combustion mechanism 5 is started or the yellow phosphorus tail gas combustion is unstable, acetylene can assist the combustion of yellow phosphorus tail gas, enhance the combustion effect, and ensure that the burner can operate stably under various operating conditions.

[0026] During operation, the combustion chamber 401 and the first sealing ring 402 are first fixed to the boiler body 1 using bolts and other connecting parts. When yellow phosphorus tail gas is introduced into the mixing chamber 506 through the yellow phosphorus tail gas inlet pipe 513, the yellow phosphorus tail gas forms a vortex flow with the primary air through the swirl vanes 514. Then, the yellow phosphorus tail gas is filtered through the filter box 510 and filter plate 512. Simultaneously, under the action of the flow equalization plate 511, the yellow phosphorus tail gas is introduced into the mixing chamber 506. Acetylene is introduced into the mixing chamber 506 through the acetylene inlet pipe 508 and ignited by the ignition needle 507. Finally... The second solenoid valve 503 opens, allowing air to enter the main combustion chamber 501 through the second air pipe 502 for combustion, and the second temperature gauge 504 monitors the temperature. At the same time, the first temperature gauge 405 monitors the temperature inside the supplementary combustion chamber 401. When the temperature is abnormal, the first solenoid valve 404 opens, allowing air to enter the supplementary combustion chamber 401 through the first air pipe 403 for combustion. This device enables the yellow phosphorus exhaust gas and air to be fully mixed before entering the main combustion chamber 501, avoiding local oxygen deficiency or fuel richness, thereby enabling the yellow phosphorus exhaust gas to burn more completely, improving combustion efficiency, and reducing pollutant emissions.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
