Description

一种快速高温蒸汽发生器 技术领域
本发明涉及蒸汽设备技术领域，尤其涉及一种快速高温蒸汽发生器。
背景技术
目前，用于厨房、消毒等蒸汽发生器中，通常采用的产汽方式有：
A.发热管直接在水箱内加热水，使水在水箱内产生饱和蒸汽，然后输出蒸汽使用，这种产汽方式蒸汽温度低，热量散失快、耗能高。
B.下面用煤气或天然气燃烧，上面一个水箱，煤气燃烧的火焰通过迂回曲折的波纹管或迷宫式的焊管，这些管浸没在水箱的水中，热气在管内走，间接加热水箱里的水产生蒸汽，这样的蒸汽发生器容易使管道内产生积炭，降低传热系数，而水箱及管外壁容易产生水垢，时间长久后热效率逐渐降低，导致蒸汽量越来越少，而且这种结构的换热管，管壁较薄，耐压低、易氧化生锈甚至破裂，整机热量散失快、耗能高，蒸汽温度低。
C.用压力锅炉产蒸汽，压力高，易积垢，危险系数高。
发明内容

为了解决上述技术问题，本发明提供了一种快速高温蒸汽发生器，包括二次加热腔和煮水腔，所述煮水腔一侧设有进水口，所述二次加热腔的上端连接有蒸汽出口管，所述二次加热器和煮水腔的连接之处设有蒸汽进口，所述蒸汽出口管内设有蒸汽管道；
所述煮水腔的下部设有发热管；
所述二次加热腔内设有蒸汽管，所述蒸汽管上端与蒸汽管道连接，下端与蒸汽进口相连接；
所述蒸汽管上设有二次发热管，所述二次发热管呈弯折状，所述二次发热 管夹持所述蒸汽管，所述二次发热管与所述蒸汽管相连接形成一体结构。
作为上述方案的改进，所述发热管至少设有2个，所述发热管呈圆环形且处于同一平面上。
作为上述方案的改进，所述二次发热管呈U形或螺旋形。
作为上述方案的改进，所述二次发热管设有多个，多个二次发热管均匀分布。
作为上述方案的改进，所述二次发热管与所述蒸汽管通过铸铝熔铸为一体。
作为上述方案的改进，所述蒸汽管呈螺旋状。
作为上述方案的改进，所述蒸汽管包括设有水汽通道的管体，所述水汽通道内设有弹簧条，随着水汽通道内的温度变化，所述弹簧条发生热胀冷缩。
作为上述方案的改进，所述蒸汽管通过如下方法制得：首先将弹簧条由管体的一端套入水汽通道内，然后通过弯管机将设有弹簧条的管体进行弯曲成型加工以使管体呈螺旋状，所述弹簧条的长度和外径与所述管体的长度和内径相适配。
作为上述方案的改进，随着水汽通道内温度变化，所述弹簧条的线径、螺旋直径以及螺距均发生变化。
作为上述方案的改进，所述管体在进行弯曲成型加工之前，管体的内壁与弹簧条之间的间隙为0.5-2mm；
所述弹簧条的线径范围为1-3mm；
所述管体的管壁厚度范围为0.6-2.5mm；
所述管体的内径范围为6-30mm；
所述管体由304不锈钢或316不锈钢制成；
所述弹簧条由304不锈钢或316不锈钢制成。
实施本发明，具有如下有益效果：
一、本发明快速高温蒸汽发生器，包括二次加热腔和煮水腔，所述煮水腔的下部设有发热管，所述二次加热腔内设有蒸汽管，所述蒸汽管上端与蒸汽管道连接，下端与蒸汽进口相连接；所述蒸汽管上设有二次发热管，所述二次发热管呈弯折状，所述二次发热管夹持所述蒸汽管，所述二次发热管与所述蒸汽管相连接形成一体结构。本发明结构简单合理，利用发热管加热产生饱和的蒸汽，再利用二次发热管把蒸汽加热，使蒸汽可广泛用于厨房、烹饪、消毒及清 洁等方面；二次发热管夹持蒸汽管，使用铸铝熔铸形成一体，其热损失少，出蒸汽时间比普通加热方式快；二次加热腔内可方便维护，操作方便；水在煮水腔内加热，蒸汽新鲜洁净，可防止产生水垢堵塞蒸汽管。
二、本发明采用特制的蒸汽管，蒸汽管内设有弹簧条，且采用特定方法制成，具有下述优点：
1、本发明通过在管体内直接设置弹簧条，水汽通道内的水蒸汽经过弹簧条时，会受到弹簧条的阻挡，水蒸汽移动速度减缓，水蒸汽在管体内加热的时间也会增加，另外，经过弹簧条的水蒸汽会随着弹簧条的螺旋外形进行螺旋移动，以使水汽通道内的水蒸汽能够均匀受热，并且可以增加水蒸汽移动的路径，从而进一步增加水蒸汽在管体内加热的时间；
2、本发明通过弹簧条自动去除水垢，当快速高温蒸汽发生器工作时，管体内温度增加，即弹簧条受热膨胀，此时，弹簧条及管体在温度变化不大的高温环境下通过水蒸汽，就算有机会产生水垢粘附，当快速高温蒸汽发生器停止工作，管体内温度慢慢下降，弹簧条冷却后收缩，相应的，弹簧条的螺距以及弹簧条与管体内壁之间的间距发生变化，此时，粘附在弹簧条表面的水垢由于弹簧条的收缩而脱离弹簧条及管体内壁，另外，当下一次再工作时，管内温度再次升高，如果管体内还有水垢粘附，水垢在干燥高温环境下也会破裂脱落，当管体内温度上升达到设定的进水蒸汽温度时，常温水蒸汽流经至容易积聚水垢的管体前部分位置，水垢马上降温破裂并脱落，随汽流排出水汽通道，保证管体内干净；
3、相对现有技术的波纹管，本发明无需对管体的内壁进行加工，其壁厚相对较厚，可以承受更大的压力，不容易产生破裂的现象；
4、本发明将管体设置为螺旋状，便于弹簧条的定位，弹簧条无需其它连接部件进行连接，从而简化蒸汽管的结构，另外，螺旋状的管体在较小的空间即可实现较长的水蒸汽通道路径，可以增加水蒸汽的加热的时间，便于水蒸汽的继续升温，并且螺旋状的管体可以减小其管体内水蒸汽的流速，进一步增加水蒸汽加热的时间。

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。仅此声明，本发明在文中出现或即将出现的上、下、左、右、前、后、内、外等方位用词，仅以本发明的附图为基准，其并不是对本发明的具体限定。
参见附图1，本发明公开了一种快速高温蒸汽发生器，包括煮水腔1和二次加热腔2，所述煮水腔1一侧设有进水口4，所述煮水腔1的下部设有发热管5；
所述二次加热腔2的上端连接有蒸汽出口管3，所述二次加热器2和煮水腔1的连接之处设有蒸汽进口8，所述蒸汽出口管3内设有蒸汽管道9；所述二次加热腔2内设有蒸汽管6，所述蒸汽管6上端与蒸汽管道9连接，下端与蒸汽进口8相连接；所述蒸汽管6上设有二次发热管7，所述二次发热管7呈弯折状，所述二次发热管7夹持所述蒸汽管6，所述二次发热管7与所述蒸汽管6相连接为一体结构。
优选的，所述发热管5至少设有2个，所述发热管5呈圆环形且处于同一平面上，既可以节省空间，又可以增加发热面积，提高发热管产生的饱和蒸汽的量和速度。
所述二次发热管7呈U形或螺旋形。优选的，参见附图2，所述二次发热管7呈U形。所述二次发热管7设有多个，多个二次发热管7均匀分布。所述二次发热管7与所述蒸汽管6通过铸铝熔铸为一体，其热损失少，出蒸汽时间比普通加热方式快50％，节能50％。
本发明工作原理如下：当水从进水口4进入煮水腔1进行第一次加热时，可在发热管5的作用下产生100℃的水蒸汽，然后100℃的水蒸汽再通过蒸汽进口8进入二次加热腔2内的蒸汽管6，在二次发热管7的作用下使水蒸汽继续充分加热，控制水蒸汽温度在100℃-300℃之间。
本发明结构简单合理，利用发热管5加热产生饱和的蒸汽，再利用二次发热管7把蒸汽继续加热，使蒸汽可广泛用于厨房、烹饪、消毒及清洁等方面；二次发热管7夹持蒸汽管6，使用铸铝熔铸形成一体，其热损失少，出蒸汽时间比普通加热方式快；二次加热腔2内可方便维护，操作方便；不间断水在煮水腔1内加热，产生洁净蒸汽，可有效防止产生水垢堵塞蒸汽管。
进一步，本发明采用特制的蒸汽管6，蒸汽管6内设有弹簧条62，且采用特定方法制成。具体参见附图3至附图6，所述蒸汽管6呈螺旋状。
所述蒸汽管6包括设有水汽通道61的管体60，管体60的两端分别为进汽口61a和出汽口61b，外部的水蒸汽通过进汽口61a进入水汽通道61内，然后由出汽口61b喷出，
为了达到本发明的目的，所述蒸汽管6还包括弹簧条62，所述弹簧条62设于水汽通道61内，随着水汽通道61内温度变化，所述弹簧条62产生热胀冷缩现象，所述弹簧条62为常见的螺旋形结构，此时，结合弹簧条62相对较高的弹性以及螺旋结构，弹簧条62活动的变化相对较大，所述弹簧条62的线径、螺旋直径以及螺距均发生变化，即弹簧条62的径向和长度方向均产生扩张或者收缩，此时，就算蒸汽管粘附有少量水垢，也可以实现切底全面清除，弹簧条62的线径即制作弹簧条62使用的弹簧丝的直径，弹簧条62的螺旋直径即弹簧条62在与其轴向垂直的面的投影的直径，弹簧条62的螺距即弹簧相邻两圈中心的轴向距离。
优选的，所述管体60由304不锈钢或316不锈钢制成，所述弹簧条62由304不锈钢或316不锈钢制成，管体60和弹簧条62的材料选择304不锈钢或316不锈钢，可以有效防止管体60内壁和弹簧条62由于长时间工作而被腐蚀掉，避免由于腐蚀溶解和剥落而影响水蒸汽的卫生。
所述管体60为螺旋状结构，所述蒸汽管通过如下方法制得：
首先将适当长度和外径的弹簧条62由管体60的一端套入水汽通道61内(如图4所示)，所述弹簧条62的长度和外径与所述管体60的长度和内径相适配，然后通过弯管机将设有弹簧条62的管体60进行弯曲成型加工以使管体60呈螺旋状，得到成品(如图3所示)。具体长度和外径由蒸汽管的应用领域决定，当需要水蒸汽流量较大时，管体60的长度以及内径相对较大，此时弹簧条62的长度和外径相对选择较大的。所述管体60在进行弯曲成型加工之前，管体60 的内壁与弹簧条62条之间的间隙L优选为0.5-2mm，将管体60和弹簧条62的间隙控制在0.5-2mm，保证弹簧条62不会影响管体60后续的弯曲成型加工，并且将管体60和弹簧条62设置一定的间隙，为管体60以及弹簧条62的热胀冷缩预留一定的空间。
首先将弹簧条62置于水汽通道61内，此时，弹簧条62会相对管体60移动，若要结构稳定，则需要通过设置连接结构或者其它连接件进行连接，本发明则通过弯管机将设有弹簧条62的管体60进行弯曲成型加工，置于管体60内的弹簧条62也随着管体60一同弯曲，此时，弹簧条62由于弯曲的结构不容易出现移位的现象，可以起到很好的稳固作用，此时，弹簧条62无需其它连接部件进行连接，本发明的蒸汽管结构简单、加工简便，并且水汽通道61内的水流不会受到其它连接件的影响。
本发明通过弹簧条62以及管体60的螺旋状加长水汽通道61内水蒸汽加热的时间，具体的，水汽通道61内的水蒸汽流经过弹簧条62时，会受到弹簧条62的阻挡，水蒸汽移动速度减缓，水蒸汽在管体60内加热的时间也会增加，另外，经过弹簧条62的水蒸汽会随着弹簧条62的螺旋外形进行螺旋移动，以使水汽通道内的水蒸汽能够均匀受热，并且可以增加水蒸汽移动的路径，从而进一步增加水蒸汽在管体60内加热的时间，螺旋状的管体60在较小的空间即可实现较长的水汽通道61路径，可以增加水蒸汽加热的时间，便于水蒸汽的再次充分加热，并且螺旋状的管体60可以减小其内水蒸汽的流速，进一步增加水蒸汽加热的时间，本发明结合弹簧条62的螺旋状以及管体60的螺旋状，使水汽通道61内的水蒸汽得到最长的加热时间，保证水汽通道61内的水蒸汽继续加热升温，达到设定的温度再通过出汽口喷出。
进一步地，所述管体60的两端设有缩口部，所述缩口部的内径小于弹簧条62的外径，通过缩口部防止弹簧条62由于特殊情况滑出管体60，保证蒸汽管能够安全工作，本发明的缩口部通过管道缩口机加工制得，并且缩口加工在弹簧条62套入水汽通道61之后以及管体60进行弯曲成型加工之前进行，可以防止管体60在弯曲成型加工时出现弹簧条62滑落等意外情况。
为了简化结构，如图6所示，去除管体60与其它结构的焊接工序，本发明在所述管体60的两端设有连接螺纹63，通过螺纹连接结构简单，并且可更换性强。
所述管体60进行弯曲成型加工后优选为圆柱螺旋状或者圆锥螺旋状，在实现水变成水蒸汽的基础上尽量减小工件所占用的空间，圆柱螺旋和圆锥螺旋相对比较稳固，并且便于蒸汽管的安装。
如图5所示，所述管体60的内径D1范围优选为6-30mm，管体60的内径太小，不利于水垢杂质的排出，管体60的内径太大，对于生产场地和加工机械要求比较高，且制造成本高，由于弹簧条62和管体60之间的间隙L范围确定、管体60的管壁厚度范围确定，所以弹簧条62的外径D2的范围也确定；对应管体60的内径范围优选为6-30mm，所述弹簧条62的线径范围优选为1-3mm，弹簧条62的线径即制作弹簧条62使用的弹簧丝的直径，当弹簧条62的线径处于此范围时，弹簧条62可以起到比较好的阻隔水蒸汽移动速度的作用，如果弹簧条62的线径太小，对水蒸汽移动起不到阻隔缓冲作用，如果弹簧条62的线径太大，对于加工难度和成本都有很大的影响。
管体60的管壁厚度范围优选为0.6-2.5mm，此时，管体60的耐压较大，不容易发生破裂，如果低于这个范围，管体会因为太薄容易发生破裂现象，如果高于这个范围，管体会因为太厚不容易加工。
本发明结合管体60的内径D1范围、管体60的管壁厚度范围、弹簧条62的线径范围以及管体60和弹簧条62之间的间隙范围L，保证管体60内的水蒸汽的流速相对较为迟缓，对水汽通道61内的水蒸汽进行充分加热，并且本发明的蒸汽管处于此组合范围时，可以实现较佳的水垢清除。本发明也可以根据具体应用对上述各个范围进行适当的调整，并不局限与本发明的范围。
综上所述，本发明结构简单合理，利用发热管加热产生饱和的蒸汽，再利用二次发热管把蒸汽加热，使蒸汽可广泛用于厨房、烹饪、消毒及清洁等方面；二次发热管夹持蒸汽管，使用铸铝熔铸形成一体，其热损失少，出蒸汽时间比普通加热方式快；二次加热腔内可方便维护，操作方便；水在煮水腔内加热，蒸汽新鲜洁净，可防止产生水垢堵塞蒸汽管。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
