Description

一种玻璃窑炉鼓泡装置 技术领域
本发明涉及玻璃生产鼓泡技术领域，具体涉及一种玻璃窑炉鼓泡装置。
背景技术
鼓泡是向玻璃液中鼓入具有一定压力的气体或液体，在玻璃液中形成气泡，在玻璃液中产生一系列的物理化学作用。鼓泡能加快澄清与均化的过程，改善池深方向玻璃液之间的热传递，减小了它们的温差，提高了底层玻璃液的温度，改善玻璃液之间的热交换，提高窑炉的熔化能力。还有一些功能介质鼓泡能消除玻璃液中杂质，提高玻璃质量。
现有的鼓泡器都是只释放一种介质，在玻璃液中需要吹入多种功能介质时，通常分别采用独立鼓泡器，这样窑炉底部需要设置很多鼓泡器，增加了结构复杂性，不便于维修。另外一些液体和粉状的鼓泡介质，在玻璃液中扩散性差，不能很好地在玻璃液中均匀扩散。
发明内容
为了克服上述现有技术的不足，本发明的目的是提供了一种玻璃窑炉鼓泡装置。
为达到上述目的，本发明解决其技术问题所采用的技术方案是：一种玻璃窑炉鼓泡装置，包括主管体，所述主管体的顶端为出气口，所述主管体上还设有至少两个连通到主管体管腔的分支管路，各分支管路内通入鼓泡介质，各分支管路上都设有单向阀。
本发明相较于现有技术，采用多种气体/液体/微粉作为鼓泡介质，同步进行更多的化学作用，减少鼓泡装置的配置，简化了玻璃窑炉的结构，提高了产品质量和生产效率。
进一步地，所述分支管路内的鼓泡介质为压缩空气、氧气、氮气、天然气、混合可燃气体、液体、消泡剂或者化学粉剂微粒。
进一步地，各分支管路内的鼓泡介质为相同类型的鼓泡介质或为不同类型的鼓泡介质。
进一步地，各分支管路内的鼓泡介质至少一种为气体介质。
采用上述优选的方案，可以通过气体介质提高液体或微粉介质在玻璃熔体中的扩散能力。
进一步地，各分支管路上都设有流量计和流量调节阀，还包括控制器，所述控制器与各流量计和流量调节阀信号连接，所述控制器接收各流量计检测的流量信号并根据设定的各分支管路介质流量比例，发出控制各流量调节阀动作的指令信号。
采用上述优选的方案，通过控制器自动控制各鼓泡介质的比例，也方便进行调节，提升鼓泡质量。
进一步地，还包括一从所述主管体底部穿设的内管，所述内管形成第一分支管路，所述主管体的侧壁上连接有第二分支管路，所述第一分支管路和第二分支管路内的介质分别为燃气和助燃气体或者分别为助燃气体和燃气。
采用上述优选的方案，通过助燃气体和燃气在炉底燃烧，提高底部玻璃熔体的温度，提高整炉玻璃熔体的温度均衡度，提升玻璃制品整体质量。
进一步地，主管体顶部为收口结构。
采用上述优选的方案，起到稳流作用。
进一步地，其中助燃气体的实际通入流量大于正常与燃气充分燃烧所要消耗的流量。
采用上述优选的方案，部分助燃气体参与底部燃烧供热，另一部分助燃气体参与鼓泡，继续向上移动换热。
进一步地，所述第一分支管路内通入的介质为助燃气体，所述第二分支管路内通入的介质为燃气，所述主管体的底部还设有用于调节内管上下位置的移动调节机构。
采用上述优选的方案，可以通过调节内管的上下位置来调节火焰状态，提高火焰稳定性和穿透性。
进一步地，所述第一分支管路内助燃气体的流量为t 0，所述第二分支管路内燃气的流量为t 1，则t 0＝(1.6-20.0)t 2，t 2为正常与t 1流量的燃气充分燃烧所消耗的助燃气体的流量。
采用上述优选的方案，使底部加热和热交换能力达到最优，达到炉内玻璃熔体整体温度均衡。
