Description

热载体超高密集烤烟烘烤房 技术领域
本发明涉及热载体超高密集烤烟烘烤房。
背景技术
烟叶是化学组分特别复杂的植物之一。烤烟烘烤的目的是把这些组分物质在实时精准控制温度、相对湿度的环境下，通过酶促生物化学反应，使其发生降解并向期望的化学反应方向重组，也使部分有害物质逸散，随后进行物理干燥，把已获得的色、香、味品质固定下来。
目前的密集式自动化烤烟烘烤房，其功能不能达到烘烤曲线对温度、湿度依时序、分时段各自不同的上下限控制值的精准要求。原因是其结构的不够合理，具体如下：
1、只用铁板(管)隔开明火而获得循环热空气的烤烟烘烤房，热空气的实际最高温度值无法控制。这个高温温度，那怕只是瞬时存在的冲击高温，都有可能使部分烟叶的酶失去活性，最终烤烟出现青干，或者只是青干斑点的缺陷。而目前其采用的是普通温度计来监控热空气的温度，但由于热惰性的缘故来不及反映这个冲击高温，从而制约了烤烟的质量；
2、烘烤房本体内的热风进出口，无论其开口位在烘烤房的任何位置，如果只是空筒式的风口，它都会在烘烤房本体内形成相对明显、固定的风路，这就决定了烘烤房本体内纵向和横向的温度、湿度都不会很均匀，最终则难以达到烤烟质量的均衡；
3、无论是自动控制还是人工控制，目前的各种烤烟烘烤房，当湿度(也有 用干湿球温度计来表述)显示超过设定该时段控制的上限值时，则同时打开天地窗口，加压或自然让房外的新鲜空气进入房内排走，从而置换烘烤房本体内湿度超标的空气。这种形式的空气置换，无疑又在烘烤房本体内形成了相对明显的风路。另外，降湿必然也加速鲜烟叶水份的汽化而降低温度，临近风路的区域降湿降温比其他区域就会多很多，烘烤房本体内必然会出现温度、湿度很不均衡的问题。
4、目前各种烤烟烘烤房，在温度、湿度的动态调整过程中，无论是进行升温加湿(湿度由于鲜烟叶自身的新陈代谢呼出水份和外加热能而提高了蒸汽压差，至使环境湿度总是自然趋向于饱和状态)或降湿降温的运作，都在烘烤房本体内形成了相对明显、固定的风路。这样，在离风道比较远一点的地方，特别旮旯之地，会形成相对封闭、半封闭的小环境，温度、湿度都会积累得很高，最严重的更会引起局部烟叶腐烂变质。所以，这些烘烤房的烟叶密集程度，都不可能设计得很高，特别是不能用于为了去筋烘烤而采取笼箱装堆层的形式，因为那会因局部排湿不畅而带来腐烂的风险。

相比现有技术，本发明的有益效果在于：
(1)本发明的热载体可以持续不断地给第一离心机输出的风进行加热，而由于热载体温度被加热装置更加精准控制，从而使热风得到的热能也在精准可控的温度范围之内，经分配装置、导叶和风头对热风进行旋转均匀分配后，热风被旋转后，使热风在旋转过程中形成近似脉冲式地供给，然后呈散落状行进，最后进入第一集气管道作再次循环，这种供热风的方式，使烘烤本体内各处温度比较均衡且有穿透力，从而使烘烤房本体内可进行超高密集地放置新鲜烟叶进行烤烟，保障了超高密集烤烟烘烤房本体内温度的稳定性和均衡性，利于提升烤烟质量；

(3)本发明加热炉的鼓风机的启或停，是由置于水箱中的第一温度传感器反馈热载体的温度信号后经自动控制系统实现的，所实现的是相当于伺服供热的方式，使热载体的上、下限温度值都是明确的、受控制的，进一步保障了烘烤房本体内控温的精准；
(4)本发明通过边沿固定在供热支管出口端内壁的导叶，把来风改变为有旋转动势的风，再推动下端带可转动的风头，从而旋转供给热风；因风头若只是直筒形状，必然在烘烤房本体内形成相对明显的风路，使供热不均匀，而本发明的可旋转的风头，可形成脉冲式的通风状态，更利于形成横向的、脉冲式的供热风，然后呈散落状行进，最后进入总集气装置、分集气装置作再次循环；
(5)由于烟叶新陈代谢的缘故，烘烤房本体内的温度趋向于上升，烘烤房本体内的空气相对湿度总是自然趋向于不允许存在的饱和状态，本发明通过负压排湿降温系统，以第二离心机对烘烤房本体内进行抽气，使烘烤房本体内形成空气负压以加速水的蒸发，水蒸发又会带走汽化热而降温，既可降低湿度又可降低温度，从而维持烘烤房本体内温度和湿度的稳定。而本发明所使用的总集气装置、分集气装置，利于使第一离心机、第二离心机抽气所产生的风向可更加分散，防止形成相对明显、固定的风路；
(6)为了动态地保持烘烤房本体内气压与大气环境气压的基本一致，本发明在第二离心机出风口上加装了风门装置，该风门装置的大门页在第二离心机运行时向外打开排气，在第二离心机非运行时则可因烘烤房本体内存在负压而在外部环境大气压的作用下自然向内打开小门页进气，保持烘烤房本体内外气压基本平衡，利于在烘烤房本体内形成均衡的温度、湿度，提升烤烟质量。

具体实施方式
如图1～3所示的热载体超高密集烤烟烘烤房，包括烘烤房本体、用于对烘烤房本体内提供热风的循环供热风系统以及用于控制烘烤房本体内温度和湿度的自动控制系统17，循环供热风系统包括依次连接的第一集气管道2、第一离心机3、用于加热第一离心机3输出的风的热载体49、供热管道6、用于对热风 分流的分配装置11、供热支管10、用于驱使热风产生旋转势能的导叶9和风头8；第一离心机3、热载体49和供热管道6位于烘烤房本体外，第一集气管道2的输入端伸入烘烤房本体内，供热支管10位于烘烤房本体内且以分配装置11为中心呈发散状连接于分配装置11的外周，导叶9和风头8依次连接于供热支管10的发散末端；热载体49配有用于加热该热载体49的加热装置。
热载体49可以持续不断地给第一离心机3输出的风进行加热，而由于热载体49温度被加热装置更加精准控制，从而使热风得到的热能也在精准可控的温度范围之内，经分配装置11、导叶9和风头8对热风进行旋转均匀分配后，热风被旋转后，使热风在旋转过程中形成近似脉冲式地供给，然后呈散落状行进，最后进入第一集气管道2作再次循环，这种供热风的方式，使烘烤本体内各处温度比较均衡且有穿透力，从而使烘烤房本体内可进行超高密集地放置新鲜烟叶进行烤烟，保障了超高密集烤烟烘烤房本体内温度的稳定性和均衡性，利于提升烤烟质量。
其中，如图1所示，烘烤房本体内的区域是用于放置烟叶的放置区16，可采用悬挂方式或笼箱装堆的方式进行放置。由于热风经风头8输出后形成的风路更加分散，使烘烤房本体内各处的温度更加均匀，因此可防止超高密集的烟叶。烘烤房本体的墙体18设为可承重隔热的墙体，烘烤房本体的底面1为混凝土或铺上防滑瓷砖，可承重、沥水、防滑，其下方为炉渣垫层62，如图7所示；如图1所示，烘烤房本体的顶部设为人字坡屋顶7。分配装置11用于将热风分流至各个供热支管10。
如图2～3所示，本发明的热载体49优选实施例是热载体49为水，加热装置包括保温壳体48以及均设于保温壳体48内的加热炉、水箱44、烟气排管46和供热排管43，加热炉位于水箱44下方；烟气排管46和供热排管43均为多个， 分别间隔平行排列于水箱44内，烟气排管46位于供热排管43下方，加热炉的烟气输出端经烟道47与各烟气排管46的烟气进口39连通；热载体49填充于水箱44内；保温壳体48的两侧分别设有加热进口45和加热出口40，加热进口45和加热出口40分别接通供热排管43的两端；烟气排管46的烟气出口依次经一烟气进口39、一烟囱41连通至外界。烟气排管46和供热排管43均位于水箱44内，浸没在水箱44的水(热载体49)，则加热炉产生的热能，一方面直接可对水箱44进行加热，另一方面产生的烟气还经烟气排管46来传热给水，使水充分吸收热能，并保持一定温度，加热了的水通过供热排管43向供热排管43传导热量，由供热排管43对由加热进口45进入的风进行加热形成热风，最后供给烘烤房本体内，该先加热水，再利用水来加热空气的方式利于对输出热风的温度进行有效控制和恒温控制，可防止热风的温度发生突变而影响烤烟质量。
具体地，加热炉包括鼓风机33、炉灰室35、炉桥37和燃烧室38，炉灰室35和燃烧室38均设于保温壳体48内，炉灰室35经炉桥37与燃烧室38相隔，炉灰室35的外侧接通鼓风机33，且该炉灰室35的外侧设有炉灰门34；燃烧室38的外侧设有加料门36，燃烧室38的内侧与烟道47接通；鼓风机33与自动控制系统17电连接。
其中，燃烧室38可以烧煤，也可以烧油或者是烧气。如果是用电，则以电热管直接替代烟气排管46。炉灰门34、炉灰室35、加料门36、炉桥37是为烧煤而设的，所形成炉灰可用作炉灰垫层的使用。无论使用何种燃料，其燃烧的启与停取决于鼓风机33的启动与停止。
为提供安全性能，水箱44还经一泄压阀42接通外界；为方便加水、换水，水箱44经一水闸51接通外界；为方便观察水箱44内的水量，该水箱44上还设有水位观察管50，该水位观察管50的下端接通水箱44的下部，该水位观察 管50的上端接通水箱44的上部；水箱44上设有用于检测热载体49温度的第一温度传感器5，该第一温度传感器5与自动控制系统17电连接。水箱44可以是金属箱等硬质壳体。
加热炉的鼓风机33的启或停，是由置于水箱44中的第一温度传感器5反馈热载体49/水箱44的温度信号后经自动控制系统17实现的，所实现的是伺服供热的方式，使热载体49的上、下限温度值都是明确的、受实时控制的，进一步保障了烘烤房本体内控温的精准。
在其它实施例中，也可采用加热管来加热水箱44中的水，进而通过水来加热供热排管43，用供热排管43来加热形成热风，具体是：热载体49为水，加热装置包括保温壳体48以及均设于保温壳体48内的电热管(未示出)、水箱44和供热排管43，电热管位于水箱44内并处于水箱44底部；供热排管43均为多个，分别间隔平行排列于水箱44内；热载体49填充于水箱内；保温壳体48的两侧分别设有加热进口45和加热出口40，加热进口45和加热出口40分别接通供热排管43的两端；电热管与自动控制系统17电连接。由自动控制系统17根据需要来控制电热管的启停。如此可省去烟气排管46、加热炉、烟囱41。
热载体49也可采用油或高分子储能材料来代替水。
更具体地，如图1所示，导叶9设于供热支管10的出口端内壁，绕圆周方向分布并以同一方向倾斜；风头8可转动地安装于供热支管10的出口端，并位于导叶9的热风输出后方。导叶9是为风头8提供旋转动力的装置，它可以由四到六块直板片绕供热支管10的内壁斜装(正反时针方向均可)，有耐热塑料片形成形如旋转扇叶；风头8也是耐热塑料片构成百叶，形成百叶式，它位于导叶9的口沿，其通过中心轴杆上的轴承盒作悬挂式连接，形成可转动的方式，与倾斜的导叶9在转动中产生间歇式的通风效果，以形成脉冲式的热风输出。 另外，在本发明的其它实施例中，导叶9也通过独立的轴承盒与风头8作悬挂式同轴连接。这样，只要供热支管10供来热风，风头8就会向烘烤房本体内任何一个点位提供脉冲式、均衡向下散落且具有穿透力的热风。
作为本发明的一个较佳实施方式，如图1所示，热载体49超高密集烤烟烘烤房还包括用于对烘烤房本体内降压、排湿、降温的负压排湿降温系统，该负压排湿降温系统包括依次连接的总集气装置32、第二集气管道30和第二离心机21，总集气装置32设于烘烤房本体内，第二集气管道30和第二离心机21位于烘烤房本体外。通过负压排湿降温系统，以第二离心机21对烘烤房本体内进行抽气，使烘烤房本体内形成空气负压以加速水的蒸发，水蒸发又会带走汽化热而降温，既可降低湿度又可降低温度，从而维持烘烤房本体内温度和湿度的均衡。
为了动态地保持烘烤房本体内气压与大气环境气压的基本一致，如图1、图4～5所示，第二离心机21的出风口设有风门装置22，该风门装置22包括法兰盘52、小门页57及呈“回”字型的大门页54，法兰盘52安装于第二离心机21的出风口，大门页54的上端经第一铰链53铰接于法兰盘52的外表面，小门页57的上端经第二铰链56铰接于大门页54的内表面；法兰盘52的下端向外伸出有用于向外倾斜支撑大门页54的第一承载板55，大门页54的下端向内伸出有用于向内倾斜支撑小门页57的第二承载板58。
如此，在第二离心机21停机或者是烘烤房本体内外基本无气压差的情况下，大门页54和小门页57都会因重力而自然分别垂靠在第一承载板55和第二承载板58，呈虚掩状阻断着第二集气管道30的进气或者是出气；大门页54和小门页57都因自重自然回落后，各与铅垂面的夹角保持在7～8°，这样可以保持较好的自然密闭程度；当第二离心机21运行时，较高的风压(如300Pa风压)，就 会使向内开的小门页57紧紧贴靠第二承载板58上，并与向外开的大门页54一起，绕着法兰盘52而打开，由于烘烤房本体内此时没有被开启的进风通道，这就造成了烘烤房本体内较高强度的负压状态，特别有利于迅速降低烘烤房本体内的相对湿度，同时温度也会下降；当第二离心机21停机时，无论何种原因产生了哪怕是很小的负压(如20～30Pa)，向内开的小门页57都会向内打开进气(或许只是些轻微打开)，直至烘烤房本体内外空气压处于基本一致时再回落到自然悬垂虚掩关闭的状态。
本例的第一集气管道2的输入端与第二集气管道30的输入端接通。烘烤房本体内还设有多个分集气装置63，各分集气装置63各自经分集气管道64与第二集气管道2的输入端接通。所使用的总集气装置32、分集气装置63，利于使第一离心机3、第二离心机21抽气所产生的风向可更加分散，防止形成相对明显、固定的风路。
作为总集气装置32、分集气装置63的其中一个实施方式，如图6～7所示，总集气装置32与分集气装置63相同，总集气装置32包括台面板59、支撑墩61和拦物网60，支撑墩61圆周分布于台面板59的下方，支撑墩61的上端与台面板59的底面固接，支撑墩61的下端与烘烤炉本体的底面1固接，拦物网60环绕罩设于各支撑墩61外围，拦物网60的上端与台面板59相抵，拦物网60的下端与烘烤房本体的底面相抵，则可接通第一集气管道2。由于热风仅能从位于侧部的拦物网60中进入第一集气管道2、第二集气管道30和分集气管道64，因此在烘烤房本体内的热风流向可更进一步打散，使各处温度更均匀。
总集气装置32和分集气装置63均固定于烘烤房本体的底面，总集气装置32位于烘烤房本体的底面中心，各分集气装置63位于烘烤房本体的底面四周；分配装置11固定于烘烤房本体的顶部中心。总集气装置32、分集气装置63、 分配装置11的位置设置，更进一步利于烘烤房本体的各处温度、湿度均匀。
如图1所示，热载体49超高密集烤烟烘烤房还包括排水装置，该排水装置包括依次连接的排水管道23、U型弯管24和水池26，水池26上设有溢水口25；排水管道23为多条，各排水管道23的输入端分别接至第一集气管道2、第二集气管道30分集气管道64及烘烤房本体的底面1，当然，也可接至分集气管道64。如此，当水池26装满水时，各自对应的U型弯管24内就自然装满了封堵空气进出的水，前端的水可顺畅地流入各自对应的水池26中，可防止水流逆向流动；其作用是自动不间断地分别收集烘烤房本体的底面1与第一集气管道2、第二集气管道30和分集气管道64的积(凝结)水，却不影响烘烤房本体内形成负压状态。
烘烤房本体的顶部悬挂有多个用于喷出水雾的喷雾头15，各喷雾头15一一对应位于风头8的正下方。如果嫌烤好的烟叶过干发脆，可以人工短暂启动喷雾头15，喷出的水雾增湿软化烟叶，如果同时短暂启动第一离心机3驱使风头8工作，喷雾增湿软化烟叶的效果会更快更均匀一些。
烘烤房本体的墙体18上设有用于置换空气的风管14。该风管14可设为布罩风管14，平时自然下垂叠合阻断烘烤房本体内外空气的自由流动，也不影响第二离心机21启动后使烘烤房本体内形成负压；而当外部风机开动时，风管14向烘烤房本体内进风，其作用是手动调节烘烤房本体内的空气组份，特别是调整影响酶促生物化学进程的二氧化碳的浓度，利于提升烤烟质量；如果置备实时快速空气成份检测仪，又可与自动化控制系统电连接，则可提升为自动控制。
优选地，烘烤房本体的墙体18上设有玻璃窗19和外开门20。外开门20用于操作人员进入烘烤房本体内进行烟叶取放或观察。该外开门20只能向外打开，可采用加强型带防漏气橡胶边封的板房预制件，单开门双开门均可，但只可选 外拉式，当进行负压排湿降温系统运行时，则可防止门自动打开，也不会有缝隙进气。玻璃窗19用于能透过玻璃目视烘烤房本体内的情况，也可临时开窗提取空气样本进行检测。
烘烤房本体内设有用于检测烘烤房本体内空气的湿度的湿度传感器12及用于检测烘烤房本体内空气的温度的第二温度传感器13，湿度传感器12和第二温度传感器13分别电连接自动控制系统17。
鲜烟叶装入烘烤房本体后，启动烘烤，当烘烤房本体内的温度由第二温度传感器13实时探知低于设定的温度控制下限值时，自动控制系统17就会发出指令控制第一离心机3启动，鼓风机33启动，并最终通过风头8向烘烤房本体内送来脉冲、散落式的热风，直至温度达到设定该小时段的上限温度值时而停止。超高密集的鲜烟叶无疑将因自身的新陈代谢活动而释放大量的热能和水蒸气，加之从循环热风中获得热能，叠加式地增大了鲜烟叶的蒸汽压差，烘烤房本体内的湿度自然总是趋向于饱和状态。所以烘烤房本体的湿度控制，完全只在于及时排走多余的水蒸汽让相对湿度始终保持在对应时间段设定的上限值之内。第二温度传感器13和湿度传感器12无论何种原因，两个同时或者是其中之任一个先越过了自己的上限控制值时，自动控制系统17都会指令第二离心机21启动，烘烤房本体因处于负压，温度和相对湿度都会迅速下降，当两个指标无论是同时还是先后降到自己的控制下限点时，第二离心机21才根据后一个(即使分辨不出先后，也有信号检测的先后)达到下限值的信息被指令停止运行。第二离心机21停机后，小门页57会被负压向内打开而进气，直至烘烤房本体内外气压基本平衡时回落归位。
无论第二离心机21是否正在运行，只要烘烤房本体内的温度下降到低于设定该小时段的下限值，第一离心机3都会被指令开启，直至烘烤房本体的温度 值达到设定该小时段的上限值时而停止。总而言之，在第一离心机3和第二离心机21的交互作用下，烘烤房本体内将持续按时序分时段动态地保持在对应该小时间段设定的温度、湿度的控制区段之内，直至完成一个周期的烘烤工作。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
