Description
技术领域 technical field
本实用新型涉及加热设备，特别涉及一种无氧化加热炉预热段点火烧嘴装置。The utility model relates to heating equipment, in particular to an ignition burner device in the preheating section of a non-oxidation heating furnace.
背景技术 Background technique
现有技术常规连续式退火炉点火烧嘴为电磁自动点火配套带火焰检测装置。通过电极反复打火引燃煤气、空气。The ignition burner of the conventional continuous annealing furnace in the prior art is equipped with a flame detection device for electromagnetic automatic ignition. The gas and air are ignited by repeated ignition through electrodes.
现有自动点火技术优势在于：单次点火劳动强度较小，操作方便。现有技术适用于点火烧嘴分布较多的退火机组工艺段烧嘴系统，常规机组加热段采用的一般都是这种自动点火式烧嘴系统。The advantages of the existing automatic ignition technology are: the labor intensity of a single ignition is small, and the operation is convenient. The existing technology is suitable for the burner system in the process section of the annealing unit with many ignition burners. The heating section of the conventional unit generally adopts this kind of automatic ignition burner system.
但其存在如下缺陷：由于其自身高温不利的限制，要求烧嘴负荷不能过大，自动控制阀件较多且管道规格细小，所以它对管路洁净度有较高的要求，一旦管路出现氧化铁皮和密封材料残留，管路阀件处极易堵塞造成点火烧嘴不能正常工作，维护工作量很大。这是在许多运行中的机组点火烧嘴目前反映最多的问题；另外现有自动点火技术由于点火烧嘴工作的环境为高温环境，点火电极和火焰检测器均为精密电器元件，长期在此环境工作失效频率很大。而本专利技术对于管道的要求不像现有技术那样严格，且无需借助点火电极和火焰检测器均为精密电器元件，可靠性和稳定性更强。But it has the following defects: due to its own unfavorable limitation of high temperature, it is required that the load of the burner should not be too large, there are many automatic control valves and the size of the pipeline is small, so it has high requirements for the cleanliness of the pipeline. Oxidized iron scale and sealing materials remain, and the valve parts of the pipeline are easily blocked, causing the ignition burner to fail to work normally, and the maintenance workload is heavy. This is the most frequently reported problem in the ignition burners of many operating units; in addition, because the existing automatic ignition technology works in a high-temperature environment for the ignition burners, the ignition electrodes and flame detectors are all precision electrical components, and they have been in this environment for a long time. The frequency of job failures is high. However, the patented technology does not have strict requirements on pipelines as in the prior art, and does not need to rely on the precision electrical components of the ignition electrode and the flame detector, so the reliability and stability are stronger.
发明内容 Contents of the invention
本实用新型的目的在于设计一种无氧化加热炉预热段点火烧嘴装置，克服现有技术对于电极和火焰检测元件的依赖，达到在高温环境下稳定可靠的目的。The purpose of this utility model is to design an ignition burner device in the preheating section of a non-oxidation heating furnace, which overcomes the dependence of the prior art on electrodes and flame detection elements, and achieves the purpose of being stable and reliable in a high temperature environment.
为达到上述目的，本实用新型的技术方案是：In order to achieve the above object, the technical scheme of the utility model is:
一种无氧化加热炉预热段点火烧嘴装置，其包括，平衡罐，其一端设置防爆膜；至少二个点火烧嘴，分别通过燃气支管连接至平衡罐；至少二个平衡烧嘴，分别通过燃气支管连接至平衡罐；混合总管，其一端连接平衡罐，混合总管上连接有燃气管道和空气管道，燃气管道和空气管道上分别设置调节阀和压力检测装置；调节控制模块，所述的各调节阀和压力检测装置分别连接调节控制模块；点火棒，连接至燃气管道。An ignition burner device in the preheating section of a non-oxidation heating furnace, which includes a balance tank, one end of which is provided with an explosion-proof film; at least two ignition burners are respectively connected to the balance tank through gas branch pipes; at least two balance burners, respectively It is connected to the balance tank through the gas branch pipe; the mixing main pipe is connected to the balance tank at one end, and the gas pipeline and the air pipeline are connected to the mixing main pipe, and the gas pipeline and the air pipeline are respectively provided with a regulating valve and a pressure detection device; the adjustment control module, the said Each regulating valve and pressure detection device are respectively connected to the regulating control module; the ignition rod is connected to the gas pipeline.
进一步，所述的平衡罐上各设四个点火烧嘴和平衡烧嘴及相应的燃气支管。Further, four ignition burners, balance burners and corresponding gas branch pipes are arranged on each of the balance tanks.
连续式无氧化加热退火机组预热段温度较低，在正常生产时候温度一般低于800℃，并且预热段需要将无氧化加热段未燃尽的煤气在此充分燃烧，所以预热段对点火烧嘴的稳定性、可靠性要求很高。The temperature in the preheating section of the continuous non-oxidizing heating and annealing unit is relatively low, and the temperature is generally lower than 800°C during normal production, and the preheating section needs to fully burn the unburned gas in the non-oxidizing heating section here, so the preheating section is important for The stability and reliability requirements of the ignition burner are very high.
本实用新型将煤气、空气压力调节由燃气支管改为在混合总管进行，可以有更高的控制精度和更强的抗管道堵塞能力；在烧嘴根部设置点火孔，进行直接引燃点火。煤气、空气进入混合罐充分混合，由压力检测调节控制二者的配比。混合罐、空气管、煤气管各自进行压力检测，通过对火焰的观测，在调整好以后保持其压力稳定在该水平。The utility model changes the gas and air pressure adjustment from the gas branch pipe to the mixing main pipe, which can have higher control precision and stronger pipeline blockage resistance; an ignition hole is set at the root of the burner for direct ignition. The gas and air enter the mixing tank and are fully mixed, and the ratio of the two is adjusted and controlled by pressure detection. The mixing tank, air pipe, and gas pipe are tested for their respective pressures, and the pressure is kept stable at this level after adjustment through the observation of the flame.
混合罐一端设置防爆膜，防止调整空煤比后的第一次点火发生爆燃。防爆膜朝向炉壳，使之在爆破瞬间冲击力在炉壳释放。An explosion-proof membrane is installed at one end of the mixing tank to prevent deflagration at the first ignition after adjusting the air-to-coal ratio. The explosion-proof membrane faces the furnace shell, so that the impact force is released on the furnace shell at the moment of blasting.
本实用新型的有益效果：The beneficial effects of the utility model:
1.通过总管调节保证精度和抗堵塞，大大提高了烧嘴的稳定性；1. Through the adjustment of the main pipe, the accuracy and anti-clogging are guaranteed, which greatly improves the stability of the burner;

4.通过以上一系列技术措施保证了点火系统可靠性、稳定性和安全性。适用于无氧化加热炉预热段这种低温情况下，燃烧条件较差的环境对于点火烧嘴稳定性要求极高的区域。4. Through the above series of technical measures, the reliability, stability and safety of the ignition system are guaranteed. It is suitable for the low temperature condition of the preheating section of the non-oxidation heating furnace, the environment with poor combustion conditions, and the area where the stability of the ignition burner is extremely high.

具体实施方式 Detailed ways
参见图1，本实用新型的一种无氧化加热炉预热段点火烧嘴装置，其包括，平衡罐1，其一端设置防爆膜2；至少二个点火烧嘴3、3’，分别通过燃气支管4连接至平衡罐1；至少二个平衡烧嘴5、5’，分别通过燃气支管4’连接至平衡罐1；混合总管6，其一端连接平衡罐1，混合总管6上连接有燃气管道7和空气管道8，燃气管道7和空气管道8上分别设置调节阀9、9’和压力检测装置10、10’；调节控制模块11，所述的各调节阀和压力检测装置分别连接调节控制模块；点火棒12，连接至燃气管道7。Referring to Fig. 1, a kind of ignition burner device of preheating section of non-oxidation heating furnace of the present utility model, it comprises, balance tank 1, and its one end is provided with explosion-proof film 2; The branch pipe 4 is connected to the balance tank 1; at least two balance burners 5, 5' are respectively connected to the balance tank 1 through the gas branch pipe 4'; the mixing main pipe 6 is connected to the balance tank 1 at one end, and the gas pipeline is connected to the mixing main pipe 6 7 and the air pipeline 8, the gas pipeline 7 and the air pipeline 8 are respectively provided with regulating valves 9, 9' and pressure detection devices 10, 10'; the regulation control module 11, the various regulating valves and pressure detection devices are respectively connected to the regulation control Module; ignition rod 12, connected to gas pipeline 7.
在本实施例中，所述的平衡罐1上各设四个点火烧嘴和平衡烧嘴及相应的燃气支管。In this embodiment, the balance tank 1 is provided with four ignition burners, balance burners and corresponding gas branch pipes.
在空煤比调整初期关闭点火烧嘴阀门，通过点燃4个平衡烧嘴观察配比。确认配比符合要求后点燃一个点火烧嘴就熄灭一个平衡烧嘴，从而保证混合罐内压力不产生太大波动。点火烧嘴全部点燃后，留一个平衡烧嘴使之处于长明状态以观察火焰稳定情况，作为点火指示烧嘴。Close the ignition burner valve at the initial stage of air-to-coal ratio adjustment, and observe the ratio by igniting 4 balance burners. After confirming that the ratio meets the requirements, one ignition burner is ignited and one balance burner is extinguished, so as to ensure that the pressure in the mixing tank does not fluctuate too much. After the ignition burners are all ignited, leave a balance burner to keep it in a long-lit state to observe the flame stability and serve as an ignition indicator burner.
预热段由于其处于直火加热式连续退火烟气进入烟道的最后一组炉体，为了保证烟气排放符合环保要求，且未充分燃烧的煤气在此充分燃烧保证机组安全性，所以对点火烧嘴稳定性、可靠性提出了更高的要求。本实用新型适用于连续式退火机组预热段点火烧嘴系统。Since the preheating section is in the last group of furnaces where the direct-fired continuous annealing flue gas enters the flue, in order to ensure that the flue gas discharge meets the environmental protection requirements, and the incompletely burned gas is fully burned here to ensure the safety of the unit, the The stability and reliability of the ignition burner put forward higher requirements. The utility model is suitable for an ignition burner system in the preheating section of a continuous annealing unit.
