Description

一种人造龙卷风发电装置及其发电方法 所属技术领域
本发明涉及一种可再生能源发电装置及其发电方法， 特别涉及一种人造 龙卷风发电的装置及其发电方法。
背景技术
随着现代科学技术迅猛发展和大众生活水平的不断提高， 工商业耗能和 家电耗能急剧增加， 世界能源面临紧张状态。 目前， 人们所使用的能源主要 来自于煤、 石油、 天然气、 核反应堆及水力发电。 这些能源中多数存在资源 有限和环境污染， 且远不能满足人们的需求。 鉴于此， 多年来就有人在探索、 开发 "绿色能源"， 如太阳能、 海洋能、 生物能、 风能等。 但是， 对于如何应 用地球大气对流层中蕴藏着的巨大能源， 却少有人研究。
自然界的龙卷风是一种气候现象， 它具有很大的破坏力， 可给人们带来 莫大的灾害。 同时也显示， 龙卷风这种对流层大气运动的特殊形式具有巨大 的能量。 龙卷风是大气对流层下部 （地面） 热空气剧烈上升， 上部冷空气急 剧下降的强对流气候所致， 其直径从几米到数十米、 数百米不等， 风速通常 在 100m/ s〜150m/ s之间， 有的可达 200m/ s， 其吸引力主要来自于它的 高速气旋所产生的负压（上升型龙卷风）。龙卷风实际上是一种管状高速气旋， 在北半球逆时针旋转及南半球顺时针旋转时， 即产生上升型龙卷风， 其气旋 中心的压力极低， 可低至 20千帕左右， 而一个标准大气压为 101.325千帕， 这样低的负压具有非常强大的吸引力， 故其破坏力很大。然而，我们可以"变 害为利"， 即根据自然龙卷风产生的原理.， 人为地制造高速气旋， 从而引发类 似龙卷风样的强大空气流并用于发电。
至今， 关于人造龙卷风的技术概括起来主要有两种方法： 其一是 "斜门 风塔"型， 即建一座具有数扇统一斜向开启小门的风塔， 当自然风吹进风塔 时， 由于 "斜门"导向的结果， 使进入塔内的空气形成气旋从而产生龙卷风 效应。 具 "气象万千" 网 (www.il 121. net)称， 这样的 "人造龙卷风"发电功 率比同样大小的风机大 10倍， 例如流体力学家严隽森的龙卷风机模型； 其二 是 "偏心射入气体"型， 即在装置的周边， 借助其他热源产生的气体或电动 鼓风机吹出的气流， 用数个喷射嘴沿圆心切线偏心将气体吹入某管道内或某 区域内， 由此产生上升气旋， 如专利号为 CN98111614.0, 申请人为陈玉德和 陈玉泽， 发明名称为 "人造龙卷风发电系统" 的发明专利说明书， 以及专利 号为 CN96109612.8, 申请人为 "株式会社统能克斯"， 发明名称为 "人造龙 卷风发生机构及其利用装置" 的发明专利说明书就公开了这样一种利用人造 龙卷风发电的装置。 但就电能产生而言， 目前此类技术尚未达到提供规模电 力的实用水平。 其存在的不足为： 一是原动力不理想， 如自然风的不稳定性、 加热空气或电动鼓风需要消耗其他能源； 二是所产生的气旋在普通管道内或 局部空间上升时， 因周边气体受到管壁摩擦力的阻滞作用， 气旋会逐渐减弱， 中心负压减小乃至消失， 不能形成龙卷风效应； 三是管道长度不够， 达不到 类似龙卷风的强大气流。 因此， 要使人造龙卷风提供足够的动力能源， 还需 要另劈途径。
发明内容
为了克服现有自然风力发电和现有人造龙卷风发电装置的上述不足， 本 发明所要解决的技术问题是提供一种利用大气对流层空气对流规律， 通过引 导上升气流形成高速气旋， 从而产生可控龙卷风并用于发电的人造龙卷风发 电装置及其发电方法。
本发明解决其技术问题所采用的技术方案是： 该人造龙卷风发电装置， 包括大口径管道系统和发电机， 管道系统由进风窗、 滤气网、 进气斗、 叶轮 管、 立式电机舱、 气流引导管、 气流加热管、 可调节通气闸门、 螺旋脊管道、 排气斗和出风窗， 按照气流的进出流向顺序连接而成， 立式发电机设置在立 式电机舱中， 卧式发电机设置在气流引导管与气流加热管之间的管路中， 螺 旋脊管道的圆形内壁上设置有沿管道轴向以螺旋形式延伸的螺旋脊， 螺旋脊 管道的出风口的位置高于进风口的位置。

具体实施方式
如图 1〜图 5所示， 本发明的人造龙卷风发电方法， 是利用大气对流层 空气对流规律， 通过螺旋脊 19管道 14沿陡峭山体铺设、 安装， 螺旋脊 19管 道 14的圆形内壁上设置的沿管道轴向以螺旋形式延伸的螺旋脊 19使其管内 流动的上升气流形成旋转的人造龙卷风， 利用该人造龙卷风带动设置在管道 系统中的发电机发电。 该方法通过以下途径实现：
一、 利用地球大气对流层空气梯度温差所致的上升气流为原动力： 根据地球大气热运动状况， 将大气分为 5层， 离地面 8000~18000米属于 对流层。 对流层内， 垂直高度每增加 100m , 温度即降低约 0.65°C， 越往高 处， 温度越低。 近地面的空气因受太阳辐射作用而获得热能， 气体膨胀， 密 度减小， 形成上升气流， 而对流层上部的冷空气则相反， 随时处于下降的趋 势。 本人用 20cm直径， 50m高的塑料管沿建筑物垂直架设的模拟实验观察 到， 一旦管道两端温差（低端温度高于高端温度）达到 0.5°C， 即可观察到管 内有明显的上升气流， 气流速度随管道两端温差值增大而加快。 此模拟实验 提示， 在地球大气对流层一定高度范围内， 若以大口径管道引导地面热空气 运动， 则可在管内形成上升气流， 管道垂直高度越高， 其两端的梯度温差值 越大， 管道内气流速度就越快， 所产生的动力也就越大。 这种管道两端促使 气流上升的梯度温差， 就是本发明 "人造龙卷风"有效的原动力， 这种现象 或原理类似于烟囱抽吸烟尘或在喀斯特地质区可见到的 "凉风洞"（常年吹风 ) 或连通器效应。 由于这种梯度温差主要取决于垂直高度， 故昼夜、 季节对 其影响不大， 可维持稳定、 持久的人造龙卷风原始动力。 对此， 现有技术尚 无先例。
二、利用间断性、不对称螺旋脊 19抽气管道的特殊装置迫使上升气流形 成高速气旋：
如果气体在平滑的管道内上升， 通常是直线流动， 多呈层流状态， 不会 产生气旋， 也就无龙卷风效应。 本发明根据流体运动可被固体导向的特性， 在气流上升的管道内壁，铸造或安装螺旋状结构的螺旋脊 19从而形成螺旋脊 管道 14， 其表面涂裹或粘贴高效保温隔热材料， 以保持管道内空气温度相对 恒定。 螺旋脊管道 14内的螺旋脊 19引导气体在上升过程中形成气旋而产生 中心负压。螺旋脊 19从大口径管道内壁低端直到高端连续设置， 使其对上升 气流全程导向， 迫使气旋逐渐加速， 气旋中心负压逐渐增大， 吸引力也随之 增强， 螺旋脊管道 14的圆形内壁上设置的螺旋脊 19全程导向上升气流， 形 成高速气旋而产生龙卷风效应。
三、 利用陡峭山体或高层建筑或支架为依托搭建螺旋脊管道 14:
现有的人造龙卷风技术没有解决好管道的垂直高度问题， 多停留在模型 阶段， 故未产生实用动力。 本发明设计在垂直高度 1000m及其以上的陡峭山 体斜行铺设螺旋脊管道 14， 或沿 300m以上的高层建筑或支架垂直搭建龙卷 风生成管道，这样能获得较大的气体梯度温差值及产生较大负压的高速气旋， 从而保证螺旋脊管道 14内气流有足够的动力冲击发电机叶轮旋转发电。
实施本发明时， 首先选择高度和陡度适宜的山体， 钻探地层， 避免松动 和易滑坡的区域， 设计为永久性建筑。螺旋脊管道 14沿陡峭山体斜行铺设或 沿高层建筑或高支架垂直搭建， 斜行铺设时其坡度应等于或大于 45° , 以减 少管道内气流阻力。气流加热管 12内设置压力传感器控制的加热器， 用于调 节和稳定管道内气流温度。 气流加热管 12长度可为 10m~20m， 该段管道外 表用绝缘耐火材料包裹， 可以平行铺设， 也可以斜行或垂直铺设。 通过气流 加热管 12与可调节通气闸门 13的调节来自动调节通气量和稳定管道内气流 温度， 气流加热管 12与可调节通气闸门 13通过自动控制系统控制， 由电脑 控制反馈调节通气量。 可调节通气闸门 13与气流加热管 12安装电脑自动控 制系统反馈调节通气量， 即通气量大于额定量时， 可调节通气闸门 13縮小， 通气量小于额定量时可调节通气闸门 13扩大， 同时气流加热管 12通电加热 管内空气， 如此可使管内气流速度基本保持恒定。 整个管道系统管腔均为圆 形， 需平滑、 流畅， 膨大或縮小处设计为流线型， 以降低气流阻力。 电机舱 数目可根据所设计人造龙卷风的功率和发电机功率而定，可建造一个至数个， 并安装相等数量的发电机。 发电机身制作为橄榄流线型， 以减少空气阻力。
其次， 制造数节段螺旋脊管道 14。 根据设计要求及交通运输条件不同， 螺旋脊管道 14长度每节可为 6m〜18m不等， 内空直径可为 3m〜18m不等， 管壁的厚度根据所用材料而异， 可为螺旋脊管道 14内空直径的 2〜5%。
电机舱用塑料制造或钢筋混凝土浇铸， 厚度根据不同材料可在 10cm~50cm之间， 其空间大小视发电机体积而定， 要求安装发电机后所剩余 空间截面积 2~3倍于螺旋脊管道 14内空截面积， 以利于空气流顺利通过， 电 机舱外以支撑架固定。
发电机根据设计功率、 外形等要求， 向厂家定制。
本发明的人造龙卷风发电装置， 包括大口径管道系统和发电机， 管道系 统由进风窗 2、滤气网 3、进气斗 4、叶轮管 5、立式电机舱 6、气流引导管 9、 气流加热管 12、 可调节通气闸门 13、 螺旋脊管道 14、 排气斗 15和出风窗 17 按照气流的进出流向顺序连接而成， 立式发电机 7设置在立式电机舱 6中， 卧式发电机 11设置在气流引导管 9与气流加热管 12之间的管路中或单独设 置的卧式电机舱中。螺旋脊管道 14的圆形内壁上设置有沿管道轴向以螺旋形 式延伸的螺旋脊 19， 螺旋脊管道 14的出风口的位置高于进风口的位置。
设置在螺旋脊管道 14的内壁上的螺旋脊 19为间断设置的多条， 与螺旋 脊管道 14的内壁相交的螺旋脊 19的上表面处的交线长度大于下表面处的交 线长度， 形成机翼的截面形状， 即上方呈弧形， 下方呈平直， 每条螺旋脊 19 靠近上方尾部之弧度大于下端起始部弧度， 此结构使气流快速旋转时产生机 翼样的升浮力， 因为螺旋脊 19是固定装置， 这种升浮作用的结果是加速管道 内气流上升。 螺旋脊 19 凸向管腔的高度为管腔直径的 5〜15%， 螺旋脊管道 14的内径可根据需要， 制造为 3m、 6m、 9m、 12m, 15m、 18m等， 螺旋脊管道 14口径越大， 管道铺设垂直高度越高， 产生的动力也就越大。 管壁厚度根据 所用材料不同而异， 以能够承载 50年自重不变形为度。管道材料可用不锈钢 制作或强度高、 韧性好的塑料制造。 可调节通气闸门 13 安装在螺旋脊管道 14的进风口处， 用不锈钢等金属制造， 用以控制通气量。
所述螺旋脊 19的螺旋升角 α最好控制在 35° ~45° 之间， 螺旋脊 19为 逆时针上升螺旋或顺时针上升螺旋。 螺旋脊管道 14的螺旋脊 19的旋向为- 北半球制造为逆时针上升螺旋， 南半球铸造为顺时针上升螺旋。
所述可调节通气闸门 13用不锈钢制造， 形状为叶片式。
所述气流加热管 12的内径与螺旋脊管道 14的内径一致， 气流加热管 12 的外表面包裹绝缘耐火材料，气流加热管 12内设置有压力传感器控制的加热 器。 管道内径须大于螺旋脊管道 14或与螺旋脊管道 14内径一致。
所述气流引导管 9呈 L形， 用不锈钢或塑料制造。
立式电机舱 6以及卧式电机舱为安装立式发电机 7和卧式发电机 11的空 间， 其净空截面积（除去发电机所占截面积）须远大于螺旋脊管道 14的截面 积， 以使气流畅通， 电机舱可用塑料制造或钢筋水泥浇铸。 叶轮管 5为安装 发电机叶轮处， 可用不锈钢或塑料制造。 气流引导管 9呈 L形， 其作用是使 垂直下降的气流转变为横向气流， 以带动平行串联的风力发电机叶轮旋转发 电， 可用不锈钢或塑料制造。 进气斗 4呈漏斗状， 最好垂直安装， 开口垂直 向上， 使人造龙卷风形成后不至于破坏地面物体。 所述滤气网 3用不锈钢丝 制作， 下方衬以钢铁支架， 网眼孔径为 1.5〜2cm， 滤气网 3 的作用是防止杂 物进入管道。 排气斗 15呈长漏斗状， 连接于螺旋脊管道 14顶端， 其作用是 降低风速、 缓解冲击力。 管道系统最前端进气斗 4上方， 安装进风窗 2， 进 风窗 2设计为迎风开启式， 即朝风来的方向开启； 山体高端管道系统尾部， 安装出风窗 17， 出风窗 17的门设计为斜开式， 其倾斜方向与气流的旋转方 向相反， 以消除气旋剩余的能量。 进风窗 2和出风窗 17用不锈钢制造， 出风 窗上方安装雨蓬及避雷针 18。
