Description

基于燃料成份的压力控制固定值调整*** 技术领域
本发明涉及一种引射式燃烧装置，特别是涉及一种引射式燃烧装置的压力控制固定值调整***。
 背景技术
在石化装置中，放空火炬***能及时处理生产装置中排放的多余、有害、不平衡的废气，并能处理试车、开停车时产生的不合格气体，以及事故时瞬时放出的大量气体，保证装置正常、安全运行。火炬燃烧要保持火焰的稳定性，若发生火焰熄灭的问题，将使大量有毒、有腐蚀、易燃易爆的气体外溢、扩散，不仅将会造成人员伤亡，污染环境，严重的会导致***、火灾。而且，燃料燃烧如果燃烧不完全，低效率燃烧，将会产生大量有害排放物，例如一氧化碳、氮氧化物等。
放空火炬***一般采用引射式燃烧装置，其使用若干文丘里燃烧器对燃气进行燃烧。燃烧器供气阀门的打开或关闭是根据燃料的压力来定的。控制阀控制流通该阀的最大燃料量，超过该燃料量，则目前开启的燃烧器无法对超出的量进行有效处理，燃烧不充分，产生大量有害排放物。因此需要开启更多的控制阀，让更多的燃烧器参与燃烧。不同燃料的成份或所含杂质不一样，阀的压力控制固定值也不一样。如果压力控制固定值与燃料成份不匹配，则火炬工况不稳定并可能产生大量有害排放物。
 技术问题
有鉴于此，本发明提出一种可解决至少一项上述问题的基于燃料成份的压力控制固定值调整***。
 技术解决方案
本发明提供一种基于燃料成份的压力控制固定值调整***，包括燃料供给管路、与所述燃料供给管路连接的若干控制阀和若干文丘里燃烧器，所述控制阀设置在所述燃料供给管路上以控制所述燃料供给管路的阀门开度，所述控制阀具有一压力控制固定值，其特征在于，所述压力控制固定值调整***包括一控制器，所述控制器与所述控制阀连接，用以根据所述燃料供给管路内的燃料的成份自动调整所述控制阀的压力控制固定值。
在一实施例中，还包括一燃料成份检测器，所述燃料成份检测器与所述燃料供给管路连接以检测所述燃料供给管路内的燃料的成份，所述燃料成份检测器与所述控制连接以将所述检测的结果传送至所述控制器。
 有益效果
综上所述，本发明提供了一种基于燃料成份的压力控制固定值调整***，利用控制器根据燃料成份自动调整控制阀的压力控制固定值，使压力控制固定值与不同燃料成份适应，提高火炬***的燃烧稳定性。
 附图说明
图1是引射式燃烧器的燃烧***的简化示意图。
图2为压力控制固定值调整***的示意图。
 本发明的实施方式
在详细描述实施例之前，应该理解的是，本发明不限于本申请中下文或附图中所描述的详细结构或元件排布。本发明可为其它方式实现的实施例。而且，应当理解，本文所使用的措辞及术语仅仅用作描述用途，不应作限定性解释。本文所使用的“包括”、“包含”、“具有”等类似措辞意为包含其后所列出之事项、其等同物及其它附加事项。特别是，当描述“一个某元件”时，本发明并不限定该元件的数量为一个，也可以包括多个。
如图1是引射式燃烧器的燃烧***的简化示意图，包括燃料供给管路10、与燃料供给管路10连接的控制阀20和文丘里燃烧器30。燃料供应管路10将来自燃料源例如油井的燃气输送至文丘里燃烧器30进行燃烧。文丘里燃烧器30的数量可以是一个或多个，数量不做限制。控制阀20设置在燃料供给管路10上以控制所述燃料供给管路的阀门开度。燃料供给管路10可具有多个支路，每个支路都设置一个这样的控制阀20并连接有一个或多个文丘里燃烧器30。图1仅示意性地画出两个支路。
控制阀20具有一压力控制固定值。对于设计定型的文丘里燃烧器而言，其能处理的燃气总量具有一最大值。因此，如果管路内的燃气的压力超过该压力控制固定值，则表示管路内的燃气量已超过所连接的文丘里燃烧器的最大处理量，此时需要开启更多支路的文丘里燃烧器对燃气进行燃烧。
对于不同的燃气，由于其含有的杂质不一样，文丘里燃烧器的最大处理量也不同。一般而言，控制阀20的压力控制固定值设置在0.8Mpa。火炬气组分包括不同的碳氢化合物，例如H2、H2S、CO2 、N2等，每种气体的相对百分比也在持续变化，从而决定了火炬的平均分子量及密度也不断变化，因此流量压力发生变化。因此，本发明的压力控制固定值调整***要针对不同的燃气成份调整控制阀20的压力控制固定值。
如图2，本实施例中，所述压力控制固定值调整***包括一控制器40和燃料成份检测器50。控制器40与控制阀20连接，用以根据所述燃料供给管路内的燃料的成份自动调整所述控制阀20的压力控制固定值。燃料成份检测器50与燃料供给管路10连接以检测所述燃料供给管路10内的燃料的成份，所述燃料成份检测器50与所述控制40连接以将所述检测的结果传送至所述控制器40。
另外，在有些情况下，在油井那里已经对燃气进行了处理，已经分析出了燃料的成份和类型，此时就不需要燃料成份检测器50的检测，只需要将燃料成份和类型输入控制器40即可。
在上述实施例中，利用控制器根据燃料成份自动调整控制阀的压力控制固定值，使压力控制固定值与不同燃料成份适应，提高火炬***的燃烧稳定性和环保性。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此，本发明的范围是由所附的权利要求，而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
