为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的 实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面结合图1至图5描述本申请实施例提供的燃烧器的控制方法、燃烧器的控制装置、燃烧器及沥青搅拌站，以及使用上述燃烧器的控制方法的电子设备。
图1示出了本申请实施例提供的燃烧器的控制方法，该方法可以应用于燃烧器的控制器中，具体包括：
步骤101：当接收到点火启动指令时，对燃烧器进行点火前的防爆燃检测，得到防爆燃检测的结果；其中，防爆燃检测包括对烘干滚筒和/或喷油阀的状态信息进行检测；
步骤102：若确定防爆燃检测的结果满足燃烧器的点火条件，控制燃烧器点火。
可以理解的是，本实施例中防爆燃检测主要指的是通过点火前对燃烧器相关部件进行状态检测，比如对烘干滚筒和/或喷油阀的状态信息进行检测，可以防止燃烧器点火前发生爆燃。
因此，防爆燃检测的主要目的在于，避免点火前燃油进入烘干滚筒内，导致烘干滚筒内燃油浓度过高，因滚筒内部温度较高或者点火瞬间而引发爆燃。
首先对本实施例中燃烧器的主要结构以及工作相关的结构进行说明，并说明燃烧器的工作原理。
参见附图2，本实施例以重油燃烧器为例，即燃烧器的燃油为重油，燃烧器通过油泵203从重油罐201中抽取重油，重油依次经重油罐201和过滤罐202后，流至油泵203，之后可以通过喷油阀205流至喷枪212处，同时，空气压缩机206还将压缩空气输送至雾化阀207处，经雾化阀207输送至喷枪212处，点火后重油经过雾化后燃烧，通过喷枪212喷射至烘干滚筒213内。
在燃烧器熄火后，可以打开吹扫阀208和雾化阀207，压缩空气经吹扫阀208输送至喷油阀205的前端，对喷油阀205前端残留的重油进行吹扫，同时，为保证气流单方向流动，吹扫阀208前端安装有第一单向阀209， 雾化阀207前端安装有第二单向阀210。
为了能够实时获知管路内的压力信息，在油泵203和喷油阀205之间还安装有第一压力传感器204，在空气压缩机206和雾化阀207之间还安装有第二压力传感器211。
同时，考虑到重油常温下粘度大、流动性差，在重油罐201至喷油阀205之间的管路外侧还设有加热设备，喷油阀205还与油泵203和过滤罐202之间的管路连通，从而可以在喷油阀205关闭时，阻断与喷枪212的通路，打开与过滤罐202的通路，便于在燃烧器点火前对重油罐到喷油阀205之间管路内的重油进行循环加热。
在示例性实施例中，确定防爆燃检测的结果满足燃烧器的点火条件的过程，具体可以包括：
若确定防爆燃检测的结果中每个目标部件的状态信息均满足目标部件对应的点火条件，确定防爆燃检测的结果满足燃烧器的点火条件；
其中，上述目标部件可以包括烘干滚筒和/或喷油阀。
可以理解的是，当接收到点火启动指令时，首先需要检测燃烧器中至少一个目标部件的状态信息，以得到防爆燃检测的结果，本实施例中目标部件主要指的是与燃烧器点火前发生爆燃问题相关的工作部件，比如燃烧器的喷油阀、烘干滚筒等。
进一步地，本实施例中烘干滚筒对应的点火条件可以包括：烘干滚筒的状态信息中所包括的烘干滚筒内部的实测负压值大于或等于预设负压值。
进一步地，本实施例中喷油阀对应的点火条件可以包括：喷油阀的状态信息中所包括的开闭状态为关闭状态。
更近一步地，若确定防爆燃检测的结果满足燃烧器的点火条件，控制燃烧器点火的过程，具体可以包括：
控制燃烧器中油泵和加热设备启动，对燃烧器中管路内的燃油进行循环加热；
在确定循环加热结束后，控制燃烧器点火。
在本实施例中，可以通过预先设定循环加热持续时长，当到达该时长时，即判定循环加热过程结束，也可以采用其他方式确认循环加热结束时 刻，具体可以根据实际需求合理设定。
考虑到燃烧器在点火阶段，如果在对燃油进行循环加热的过程中，喷油阀因卡滞失效或者其他原因不能复位，也就是说，喷油阀处于开启状态，此时燃油将通过喷枪喷射至烘干滚筒内，容易使烘干滚筒内燃气浓度过高，点火瞬间出现爆燃现象，引发安全事故。
为此，本实施例先检测喷油阀的开闭状态，在喷油阀关闭时，再控制燃油循环加热，可以有效避免上述安全问题发生。
在实际应用过程中，喷油阀上装有限位开关，限位开关用于检测喷油阀三通阀体的位置，当三通阀体处于正确位置时，即喷油阀为关闭状态时，限位开关的执行部件与三通阀体的摇臂接触，从而能够检测到限位开关信号；当三通阀体处于错误位置时，即喷油阀处于开启状态时，限位开关的执行部件与三通阀体的摇臂不能接触，此时检测不到限位开关信号，此时可以进入自动熄火模式，同时也可以输出报警信号，以及时进行报警提醒，提示工作人员喷油阀状态异常。
因此，本实施例可以通过限位开关来检测喷油阀处于开启或者关闭状态，此时喷油阀需处于关闭状态，若检测到喷油阀处于开启状态，则可以直接进入自动熄火模式，避免燃烧器点火引发爆燃危险。
本实施例中燃烧器的燃油主要指的是重油，因重油在常温下的粘度较大，流动性差，在点火前需对重油进行加热，降低其粘度后才能使用，为了提高重油的加热效率，节省加热时间，通常情况下需在加热的同时对重油进行循环，使其边流动边加热。
喷油阀为三通阀，重油循环时喷油阀需处于关闭状态(即断电后的正常状态)，若喷油阀满足关闭状态，则控制油泵和加热设备开启，此时重油开始循环加热。
此时重油流动路线为：重油罐—油泵—喷油阀—重油罐，重油不能到达燃烧器的喷枪，若喷油阀处于开启状态(即异常状态，如因喷油阀卡滞或者电磁阀卡滞导致喷油阀不能复位)，循环过程中重油流动路线为：重油罐—油泵—喷油阀—喷枪，重油通过喷枪进入烘干滚筒内部，在点火瞬间可能会造成爆燃。
在对重油进行循环加热的同时，可以实时检测烘干滚筒内部的负压值， 即实测负压值，通过将该实测负压值与预设负压值进行比较，判断是否满足点火条件，在检测到烘干滚筒内部的负压异常时，此时不满足点火条件，应自动熄火，同时，还可以输出报警信号，及时发出警报提示。
在实际应用过程中，为了确保烘干滚筒内部气体可顺利流通，避免烘干滚筒内部形成密封空间从而导致爆燃，可以通过烘干滚筒出料箱上安装的负压装置来检测烘干滚筒内的负压值，即实测负压值P，本实施例中预设负压值可以设为8mmHg，当实测负压值不满足P≥8mmHg时，此时烘干滚筒内部气体流通不畅，在点火时存在爆燃隐患，则直接进入自动熄火模式；若满足上述条件，则开始点小火，小火点着之后，开启雾化阀和喷油阀，此时重油的流动路线为：重油罐—油泵—喷油阀—喷枪，大火点着之后，可以正常运行。
在示例性实施例中，点火前的防爆燃检测过程可以参见附图3，该过程具体包括：
步骤301：判断喷油阀是否关闭；
步骤302：若是，则进一步判断烘干滚筒内的实测负压值是否超过预设负压值；
步骤303：若实测负压值超过预设负压值，则点小火，并进一步判断小火点火是否成功；本实施例中点火成功与否，具体可以通过火焰检测方式进行判断；
步骤304：若小火点火成功，则开启雾化阀和喷油阀；
步骤305：延时并检测是否有火焰信号；
步骤306：若有火焰信号，则大火点火成功，正常运行；
步骤307：若判定喷油阀未关闭、实测负压值低于预设负压值、小火点火失败和大火点火失败中至少存在其中一种情况，则发出故障报警，以提示异常状态，并控制燃烧器自动熄火。
上述防爆燃检测的过程同时包含了喷油阀的状态检测和烘干滚筒的负压检测，当目标部件既包含喷油阀又包含烘干滚筒时，可以先判断喷油阀的状态，再对烘干滚筒进行负压检测，从而可以实现负压联锁保护功能。
考虑到燃烧器熄火后，由于管路内残留部分燃油，存在爆燃隐患，不够安全可靠。为此本实施例在燃烧器的控制方法中还引入了熄火后的控制 方案。
更优地，本实施例提供的燃烧器的控制方法，还可以包括：
当接收到熄火指令时，控制燃烧器熄火，并控制燃烧器抽回管路内剩余的燃油和/或将燃烧器中管路内剩余的燃油吹进烘干滚筒中。
在示例性实施例中，控制燃烧器抽回管路内剩余的燃油的过程，具体可以包括：
控制燃烧器中的油泵反转预设时长，以将管路内剩余的燃油抽回油罐中。
在示例性实施例中，控制燃烧器中管路内剩余的燃油吹进烘干滚筒中的过程，具体可以包括：
控制燃烧器中的吹扫阀分多个时段开启，在至少一个时段内，先开启预设开启时长然后关闭预设关闭时长。
进一步地，控制燃烧器中的吹扫阀分多个时段开启，在至少一个时段内，先开启预设开启时长然后关闭预设关闭时长的过程，具体可以包括：
控制吹扫阀开启至满足第一预设开启时长后，关闭吹扫阀并延时预设关闭时长；
控制吹扫阀开启至满足第二预设开启时长后，关闭吹扫阀并延时预设关闭时长；
控制吹扫阀开启至满足第三预设开启时长后，关闭吹扫阀；
其中，第一预设开启时长和第二预设开启时长均可以小于第三预设开启时长。
需要说明的是，上述预设开启时长在设定时，可以具体设定为：第一预设开启时长<第二预设开启时长<第三预设开启时长，也就是说，在分段吹扫过程中，逐步增加吹扫时间，以保证吹扫过程的安全性。
燃烧器熄火(手动熄火或自动熄火)后，此时油泵和雾化阀关闭，随后控制油泵变频器使油泵以某频率反向转动一定时间后关闭，将喷油阀前端管道中大部分燃油回流到过滤罐中，即控制燃烧器抽回管路内剩余的燃油。
如果上述控制燃烧器抽回管路内剩余的燃油和/或将燃烧器中管路内剩余的燃油吹进烘干滚筒中，两个处理过程同时存在的话，可以在控制燃 烧器抽回管路内剩余的燃油后，再将燃烧器中管路内剩余的燃油吹进烘干滚筒中，从而能够提高管路内残留燃油的清理效率，也能够更彻底的清理管路内残留的燃油。
在将燃烧器中管路内剩余的燃油吹进烘干滚筒中时，可以利用压缩空气进行吹扫，将管道中剩余的燃油吹扫干净，避免喷枪和管道堵塞。
在示例性实施例中，控制燃烧器抽回管路内剩余的燃油后，将燃烧器中管路内剩余的燃油吹进烘干滚筒中的过程具体可以如下：
油泵反转结束后油泵停止，随后开启雾化阀，延时2s后开启吹扫阀，开启吹扫阀50ms后，关闭吹扫阀；
再延时2s后，开启吹扫阀，开启吹扫阀300ms后，关闭吹扫阀；
最后，延时2s后，开启吹扫阀，直到熄火结束。
考虑到油泵反转后喷油阀前端管道中仍然可能残留一部分重油，因此还需对其吹扫，若直接将吹扫阀和雾化阀开启，残留的重油被压缩空气通过喷枪迅速吹扫进入烘干滚筒，仍然有可能会生产爆燃。
本实施例在油泵反转停止后采用分段吹扫的方式，第一次吹扫阀开启时间50ms，第二次开启300ms，第三次连续吹扫，前两次吹扫时间较短，目的是控制重油喷出量，避免一次性喷出较多的重油，进入烘干滚筒后引起爆燃。
在示例性实施例中，控制燃烧器熄火，并控制燃烧器抽回管路内剩余的燃油和将燃烧器中管路内剩余的燃油吹进烘干滚筒中的过程，可以参见附图3，该过程具体包括：
步骤308：在手动熄火或自动熄火后，油泵和雾化阀关闭；
步骤309：油泵反转并延时，即油泵反转一定时长，以执行余油回流任务，该时长可以根据实际需要合理设定；
步骤310：油泵反转结束后，油泵关闭；
步骤311：雾化阀开启并延时，即开启雾化阀一定时长；
步骤312：之后吹扫阀分段开启并延时，即控制燃烧器中的吹扫阀分多个时段开启，在至少一个时段内，先开启预设开启时长然后关闭预设关闭时长；
步骤313：控制燃烧器抽回管路内剩余的燃油和将燃烧器中管路内剩 余的燃油吹进烘干滚筒中两个过程完成后，熄火结束。
在实际应用过程中，本实施例中吹扫阀可以采用膜片阀，膜片阀反应灵敏，可以很好的控制开启时间和关闭时间，从而提高分段吹扫过程的控制精度。
由此可见，本实施例提供的燃烧器的控制方法，通过优化燃烧器点火和熄火过程的控制逻辑，可以有效降低燃烧器在点火和熄火过程中爆燃现象发生的概率。整个燃烧器的控制方法包括燃烧器点火前控制部分和熄火后控制部分两方面。
一方面，燃烧器点火前需要进行燃油循环来提高重油加热效率，在此过程中，通过采集限位开关信号，并可以通过负压联锁保护，来避免点火阶段易引发爆燃的问题。
另一方面，燃烧器熄火后需要清理管路内残留的重油，具体地，首先采用油泵反转，将管道中大部分燃油回流到主油管路中，然后再采用压缩空气分段吹扫，将管道中剩余的燃油吹扫干净。由于可以先采用油泵反转方式进行清理，再采用分段吹扫方式进一步清理，使吹扫过程中只有少量重油，不足以引发爆燃，同时分段吹扫的方式也可以进一步降低爆燃的发生概率，安全性更高。
