Description

多级换热槽式蒸汽产生装置
技术领域
本发明涉及蒸汽产生装置领域，尤其是涉及多级换热槽式蒸汽发生装置。
背景技术
传统的高温高压蒸汽发生装置，是将液态水注入到一个密闭的加压锅内，通过对加压锅加热，使加压锅内部的水沸腾产生蒸汽，由于加压锅为一密封环境，蒸汽不会溢出，因此在水沸腾的情况下，加热锅内的压力较大，最终得到高于100℃的高温蒸汽。但因传统高温高压蒸汽发生装置的设计对加压锅本体的耐压强度要求极高，长期使用会由于机械疲劳存在较大的汽爆安全隐患，同时其产生的蒸汽温度范围较大，无法达到使用要求。
现有技术中已有一种蒸汽产生装置，通过对液体水的二次加热使液态水转换为高温高压蒸汽，其安全性能较高，能长期使用，但整个设备及其加工工艺较复杂，能耗大，且可调控性低。
发明内容
本发明要解决的技术问题是：针对上述现有技术存在的不足，提供一种多级换热槽式蒸汽产生装置。
本发明解决其技术问题的解决方案是：该多级换热槽式蒸汽产生装置，包括加热装置，所述加热装置包括换热器、发热管和蒸汽喷嘴，同时其下端设有进水口。其中：换热器，其由壳体与盖板密闭盖合而成，壳体的内表面上同轴纵向排列有呈凹槽结构的多级换热槽，换热器上端设有出汽口；发热管，其部分埋设于壳体的下部，通过与换热器紧配配合，可将热传导至多级换热槽内；蒸汽喷嘴，其与所述出汽口螺旋连接，连接处设有阀门；
其中发热管的加热温度可控，可将加热器预热至所需加热温度。
该多级换热槽式蒸汽产生装置，还包括注水泵，其上下两端分别设有吸水口和注水口，所述注水口连接有进水管道，并与所述进水口通过进水管接头连通；
该多级换热槽式蒸汽产生装置，还包括储水器，其通过吸水管道与所述吸水口连通。
作为上述技术方案的进一步改进，所述注水泵上设置有注水泵保护器。
作为上述技术方案的进一步改进，所述注水泵上还设置有用于控制其注水口出水量的注水泵水量调节器。当所用液体水的水温相差较大时，可通过其调节进入加热装置内的注水量，使最终产生的高温高压蒸汽效果达到最佳状态。
作为上述技术方案的进一步改进，所述换热器上设置有常闭接点温控器和常开接点温控器。其中常闭接点温控器作为加热装置的高温限制及缺水的过温度保护；常开接点温控器作为对加热装置预热温度的监测。
作为上述技术方案的进一步改进，所述换热器还包括作用于壳体与盖板盖合处的防漏密封圈，使换热器盖合后的内部空间处于密闭状态。
本发明的有益效果是：本发明利用多级换热槽的槽式连通结构，使加热过程中液态水能在多级换热槽前半部分吸热变成饱和蒸汽后，再进入到多级换热槽后半部分进行二次吸热形成过热蒸汽，实现了高温高压蒸汽产生过程中二次加热均在同一换热器内进行，使整个加热装置结构简单，能耗低，安全性能高。
本发明通过液体水在加热过程中同时配合注水泵压力调整、注水泵注水量的调节和发热管预热温度控制，可输出不同参数的高温高压蒸汽，且输出的高温高压蒸汽可控制在一个较小的温度范围内，使蒸汽产生过程具有较高的可调控性。
本发明在换热器上设置有常闭接点温控器和常开接点温控器，同时在注水泵上设置有注水泵保护器，进一步提高整个装置的安全性能。
本发明用于将液体水转换为高温高压蒸汽。
