Description

一种改进的冷却塔塔体结构 本发明所属技术领域
本发明涉及一种冷却塔设备， 特别是一种改进的冷却塔塔体结构。 在本发明之前的现有技术
传统的方形冷却塔普遍采用由金属钢架搭建成的塔体结构， 在金属钢 架外包围一层玻璃纤维板。 如图 1所示为现有的横流式冷却塔结构图， 包 括钢架体 10、风筒 11、储水底盘 13、风机 19等， 其钢架体 10的两侧安装 有填料支架 101， 填料片 103穿设于支架 101上， 钢架体 10的外侧安装有 玻璃纤维板 12;风筒 11置于塔体顶部，且风筒 11内安装有风机 19和马达 等组件； 塔体顶部设有播水盘 107， 底部设有储水底盘 13， 该储水底盘 13 的中央部分向下凹陷形成一小的出水盆 14或出水槽， 在出水盆 14的一侧 开有进水口和出水口 16， 且该出水盆 14的四周设有中心钢支架 15; 整个 塔体 1由底部的金属支架 102和中心钢支架 15支撑。 另外， 在塔体 1的外 侧安装由扶梯 17和检修门 18。 尽管这种结构的塔体已经被行业内普遍使 用， 但是上述塔体结构仍存在许多的不足和缺陷- 制作塔体 1的钢架体 10需要耗费很多的金属材料， 而且钢架体 10两 侧的玻璃纤维板 12为单层纤维板， 该玻璃纤维板 12通过螺丝固定于钢架 体 10的两侧，仅起到装饰和密封塔体的作用，其自身并不承载塔体的重量。 由于冷却塔工作时， 塔体内有大量的水汽通过， 钢架体 10长期暴露在该环 境中， 容易被冷却水侵蚀， 导致生锈等。 而且， 单层玻璃纤维板 12的内侧 表面较粗糙， 也容易滋生细菌或微生物等。
上述填料支架 101的两端卡置于钢架体 10的两侧支架 104上 （如图 7 所示） ， 在钢架体 10的两侧支架 104上焊接有角铁 105， 填料支架 101的 两端固定放置于该角铁 105上。 使用时， 填料片 103穿设于支架 101上， 并悬挂在钢架体 10两侧， 由于钢架体 10两侧的金属支架具有一定的厚度， 因此即使填料片布满整个填料支架 101，其最末端的填料片 103与钢架体外 侧的玻璃纤维板 12之间仍存在一定的空隙 110 (如图 14所示，空隙 110的 宽度 d与钢架体 10的厚度有关），当冷却塔工作时，该空隙容易导致漏风， 使冷却效能降低。
冷却塔的进水口和出水口 16通常设置在塔底中央的出水盆 14一侧， 当需要连接水管时， 施工人员需要爬入塔底进行作业， 而塔底的空间有限， 导致施工难度增加。 另外， 该冷却塔的全部重量（包括储水底盘 13内冷却 水的重量） 由塔底的金属支架 102和中心钢支架 15承担， 因此对金属支架 102和中心钢支架 15的承载能力有较高的要求； 而且， 随着冷却塔体积的 增大， 制作金属支架 102和中心钢支架 15所需材料的成本也会随之增加。 塔体外侧的扶梯 17和检修门 18分离设置，扶梯 17与冷却塔塔体是独立的， 扶梯 17通过连接件固定与塔体一侧。
另外， 对于内进水式的冷却塔， 如图 12所示， 传统的冷却塔塔体顶部 靠近播水盘 107—侧安装有一条金属架 106，该金属架 106上开有与播水盘 107连通的安装口 108，内进水式布水管道 109经该安装口 108与播水盘 107 连通。 其缺陷是， 每座冷却塔内， 需要增加两条条类似的金属架 106。
纵上所述， 一座传统的冷却塔通常具有上百件的零部件， 需要使用大 量的螺钉或螺丝进行固定、 连接， 如果要完全组装一座这样的冷却塔， 通 常需要 2〜3天的工作时间， 不仅组装困难， 而且加工制作成本很高， 运输 也不方便。 发明目的
本发明的目的在于提供一种改进的冷却塔塔体结构， 可以减少冷却塔 的组装部件， 缩短组装时间， 降低制作成本。 本发明采用的技太方案
本发明所采用的技术方案： 一种改进的冷却塔塔体结构， 包括塔身、 风筒、 储水盆、 以及填料支架， 其特征在于， 塔身由多块玻璃纤维侧板拼 接而成， 其顶部设有播水装置， 底部与储水盆连接； 所述玻璃纤维侧板是 由两层玻璃纤维板粘合而成的中空板体。
上述中空板体的其中一层为具有连续的凹凸结构的板体， 另一层为平 面板体。
上述填料支架置于塔体一侧或两侧的进风通道内， 该支架的两端与塔 身的两侧板内侧连接。
上述塔身的侧板内侧固定有连接件， 连接件上设有横向的凸块； 所述 填料支架的两端设有凹型插槽， 该插槽与上述连接件上的凸块固定连接。
上述塔身的整个底盘四周向下延伸形成储水盆， 储水盆的底部即为整 个塔体的最低平面。 储水盆的底部设有至少三条通道， 各通道的最外端延 伸至盆体外侧。 储水盆的一侧开有进水口和出水口， 该进水口和出水口与 储水盆底部的任一条通道连通。
上述塔身的侧板中部向内弯曲形成一纵向的凹槽。 所述凹槽内设有一 检修门， 且凹槽的两侧安装有若干条横杆， 形成一扶梯。 所述凹槽内与检 修门正对的横杆可活动开启， 其一端通过枢轴与凹槽的一侧活动连接， 另 一端与凹槽的另一侧扣接。
上述风筒的侧壁上幵有布水管道的安装口， 塔体内的布水管道经该安 装口与塔身顶部的播水装置连通。
上述布水管道包括横喉、 曲喉、 中心喉和布水管， 其横喉置于储水盆 底部的任一通道内， 且一端与进水口连通， 另一端经曲喉与中心喉连通， 中心喉的顶端与布水管连通， 布水管经风筒侧壁上的安装口与播水装置连 通。 曲喉放置在一支座上， 该支座既可以通过螺丝固定于储水盆底部的底 座上， 也可以与储水盆底部的底座做成一体结抅。 所述布水管道和支座均 由玻璃纤维制成 与传统的冷却塔相比， 本发明具有以下特点：
( 1 )本发明的塔身结构完全由玻璃纤维板拼接而成， 可以完全省去传 统冷却塔中的钢架体结构， 不仅可以节省大量的金属材料， 降低制作成本， 而且由于玻璃纤维具有更强的抗腐蚀性， 不会被冷却水侵蚀。 玻璃纤维侧 板是由两层玻璃纤维板粘合而成的中空板体， 具有很强的硬度和承载能力， 质量较金属钢架轻， 减少了整个冷却塔塔体的重量， 降低运输成本； 而且 该玻璃纤维侧板的内、 外两侧表面均为光滑面， 不易滋生细菌或微生物， 方便清洗。
(2)本发明的填料支架通过塔身侧板内的连接件固定连接， 填料片穿 设于该支架上， 并悬挂在塔体的进风通道内。 当填料片布满整个填料支架 时， 其最末端的填料片可以紧贴着塔身的内侧玻璃纤维板（如图 13所示)， 中间不存在空隙， 因此， 冷却塔工作时， 就不会出现漏风现象， 可提高冷 却效能。 同时， 填料支架还可以起到对塔身两侧板的拉紧作用， 使整个塔 身保持稳固， 不会变形或倒塌。
(3 )本发明在传统冷却塔的储水底盘的基础上， 将整个底盘四周向下 延伸形成一储水盆， 该储水盆底部的大部分面积可接触地面， 这样就使得 整个储水盆中冷却水的重量由地面来承担， 减轻了塔底支架的承载量； 由 于塔身由玻璃纤维板组成， 其重量较轻， 因此， 本发明的塔底的支架可以 做的很简单， 可以采用金属或 FRP材料制作， 同时也省去了传统冷却塔底 部的中心钢支架。 另外， 本发明的储水盆底部设有至少三条通道， 各通道 的最外端延伸至盆体外侧， 与进水口和出水口连通， 当需要连接水管时， 施工人员只需在储水盆的外侧安装即可， 无需再爬入塔底； 而且， 可以根 据外部的水管的走向或客户要求， 在储水盆的任意一侧开设进水口和出水 口。 当采用多组安装结构时， 可以选择与进风通道同方向的通道开设进水 口和出水口 （如图 9(c)所示）， 方便与外部供水管道连接。
(4) 本发明的塔身侧板由三块以上的玻璃纤维板拼接组成， 中间一块 玻璃纤维板上设有一纵向的凹槽， 该凹槽的两侧与相邻板体连接， 使整块 侧板形成一 "一 型结构， 该结构可以使塔身侧板具有足够的承载能 力， 支承塔体顶部的风机和马达等重量。 同时， 上述凹槽内设有检修门， 凹槽的两侧安装有若干条横杆， 形成扶梯， 其中与检修门正对的横杆可活 动开启。 其优点是扶梯、 检修门与侧板属于一整体结构， 方便安装和拆卸， 而且美观。
(5)本发明的风筒侧壁上开有布水管道的安装口 （如图 11所示）， 对于内进水式的冷却塔， 其布水管道可经过该安装口与塔身顶部的播水装 置连通， 即可省去传统冷却塔顶部的金属架。 另外， 本发明针对内进水的 布水管道， 特别设计了一支座， 该支座用于固定布水管道的曲喉部分， 该 支座可根据布水管道的安装方向调整， 既可以通过螺丝固定于储水盆底部 的底座上， 也可以与储水盆底部的底座做成一体结构。 以上的布水管道和 支座均由玻璃纤维制成， 较传统的 PVC管道， 更耐高温， 而且寿命更长。
综上所述， 本发明已与传统的冷却塔塔体结构完全不同， 其整个塔体 仅有二、 三十件部件， 可节省 70%以上的螺钉或螺丝， 大部分部件采用玻 璃纤维板制成， 不仅制作成本较低， 而且组装简单， 运输方便， 可以大大 缩短组装时间， 通常只需 2〜3小时即可组装完成一座这样的冷却塔。 该塔 体可适用于各种类型的方形冷却塔设备， 特别适合于横流式方塔。 附图说明

为了便于介绍本发明的塔体结构， 以下将通过横流式方形冷却塔为实 例进行说明：
如图 2所示， 一种改进的冷却塔塔体， 包括塔身、 风筒 6、 储水盆 5、 以及填料支架 3，其塔身由多块玻璃纤维侧板 2拼接而成，塔身顶部设有播 水装置 9， 塔身底部与储水盆 5连接； 填料片 4穿设在填料支架 3上， 并悬 挂在塔体两侧的进风通道内。 塔身的侧板 2的中部向内弯曲形成一纵向的 凹槽 23， 该凹槽 23内开有一检修门 8， 且凹槽 23的两侧安装有若干条金 属横杆 7， 形成一扶梯； 储水盆 5的一侧开有进水口 56和出水口 57， 风筒 6内可安装风机和马达等组件。
上述玻璃纤维侧板 2是由两层玻璃纤维板粘合而成的中空板体（如图 3(a)所示)， 其中一层为近似波浪型板体 21， 另一层为平面板体 22， 波浪型 板体 21的下凹部分与平面板体 22粘合， 上凸部分与平面板 22体形成空腔 体， 波浪型板体 21成为塔身的外侧， 平面板体 22成为塔身的内侧。 通常 制作的单层玻璃纤维板， 其一面为光滑面， 另一面为粗糙面， 本实施例中， 将波浪型板体 21和平面板体 22的粗糙面粘合形成侧板 2，使侧板 2的外侧 面和内侧面均为光滑面， 不仅具有较强的抗腐蚀性， 而且可以有效的防止 滋生细菌或微生物。
另外， 上述玻璃纤维侧板 2也可以做成如图 3(b)所示的结构， 其中板 体 21的上凸部分表面增加了更小的凹槽 211，板体 22为平面板，粘合关系 与图 3(a)相同； 玻璃纤维侧板 2还可以做成和图 3(c)所示的结构，其中板体 21成梯形结构， 板体 22为平面板， 粘合关系与图 3(a)相同。 本发明所述玻 璃纤维侧板的结构并不局限于以上三种结构， 凡可以由两层板体粘合而成 的中空板体（其中一层为具有连续的凹凸结构的板体，另一层为平面板体)， 均属于本发明的保护范围， 在此不再一一列举。 .，
如图 4和图 5(a)所示，塔身的两侧板 2通过交叉的金属斜拉杆 24拉紧， 在两侧的进风通道内， 填料支架 3的两端通过金属连接件 31与侧板 2固定 连接， 同时也可以起到对塔身两侧板 2的拉紧作用， 使整个塔身保持稳固。 图 6(a)所示为填料支架 3与连接件 31的分体结构图，连接件 31固定在侧板 2的内侧平面板体 22上， 该连接件 31上设有横向的凸块 32， 相应地， 在 填料支架 3的端部设有凹型插槽 34， 在凸块 32和插槽 34上对应设有螺孔 33。 将插槽 34由凸块 32上方卡入， 旋入螺丝 35即可固定连接， 如图 6(b) 所示为连接后的结构图。
另外， 上述填料支架 3也可以采用如图 5(b)所示的安装结构， 填料支 架 3为一圆形铁管，其两端部开有一段缝 301，另有一段开有凹槽 303的空 心管 302， 该空心管 302插入圆形铁管的端部， 使凹槽 303正对缝 301 ; — 连接件 306固定于侧板 2的内侧， 连接件 306上设有凸块 307。安装时， 将 填料支架 3的两端由凸块 307上方卡入， 利用一螺钉从侧板外穿过连接件 306上的螺孔 308， 并旋入空心管 302端面的螺孔 304， 使其固定连接； 也 可以使用螺丝穿过螺孔 305， 使其连接。
如图 8所示， 本发明在传统冷却塔的储水底盘的基础上， 将整个储水 底盘的四周向下延伸形成一储水盆 5，储水盆 5的底部即为整个塔体的最低 平面， 在塔体底部四周， 设有金属支架 25。 当塔体置于地面或楼顶上时， 储水盆底部的大部分面积可接触地面或楼顶面。 由于储水盆 5 中冷却水的 重量大部分已被地面承担， 因此可以减轻塔底金属支架 25的承载量， 同时 省去了传统冷却塔底部的中心钢支架。 另外， 储水盆 5 的底部还设有三条 通道 50， 用于放置进水管， 三条通道 50交汇形成 T形凹槽， 各通道 50的 最外端延伸至盆体外侧， 与进水口和出水口连通。 根据水管的走向， 进水 口 56和出水口 57可设置于储水盆 5的任意一侧， 当需要连接水管时， 施 工人员只需在储水盆的外侧安装即可， 无需再爬入塔底。
本发明的热水管道可采用内进水或外进水两种方式， 如果采用内进水 方式， 其热水经塔体内的布水管道通往塔顶的播水装置 9 内。 布水管道由 横喉 51、 曲喉、 中心喉 52和布水管 55组成， 其曲喉与横喉 51—端连通， 并与横喉 51做成一体， 横喉 51置于储水盆底部的任一通道 50内， 一端与 进水口 56连通， 另一端的曲喉部分与中心喉 52连通， 中心喉 52的顶端与 布水管 55连通，布水管 55经风筒侧壁上的安装口 61与播水装置 9连通 (如 图 11所示）。 为了保持布水管道的稳定， 上述横喉 51的曲喉部放置在一支 座 53上， 支座 53上设有与曲喉部配合的凹位， 支座 53既可以通过螺丝固 定于储水盆底部的底座 54上， 也可以与储水盆底部的底座 54做成一体结 构。如图 9(a)〜图 9(c)所示为本发明中布水管道的三种安装方式示意图，根 据外部的水管的走向或客户要求， 可采用图 9(a)〜图 9(c)中任一种安装方 式。 如图 15所示， 当采用多组安装结构时， 可以选择与进风通道同方向的 通道开设进水口和出水口， 方便与外部供水管道连接。
本发明与传统冷却塔的另一不同点在于扶梯和检修门的设计， 如图 10(a)〜10(b)所示， 塔身的侧板 2由三块以上的玻璃纤维板拼接组成， 中间 一块玻璃纤维板上设有一纵向的凹槽 23，该凹槽 23的两侧与相邻板体连接， 使整块侧板形成一 "一 u—"型结构， 该结构可以使塔身侧板具有足够的 承载能力， 支承塔体顶部^风机和马达等重量。 同时， 凹槽 23内设有一捡 修门 8， 凹槽 23的两侧安装有若干条横杆 7， 形成一扶梯， 其中与检修门 8 正对的横杆 7可活动开启。 该结构的特点是： 扶梯、 检修门与侧板属于一 整体结构， 方便安装和拆卸， 而且美观。 综合考虑整个冷却塔的塔体结构， 本发明已与传统的冷却塔塔体结构 完全不同， 该塔体仅有二、 三十件部件， 可节省 70%以上的螺钉或螺丝， 且大部分部件采用玻璃纤维板制成。 根据塔体的受力情况， 在塔体的玻璃 纤维板体表面设计有特殊的棱边结构， 在储水盆的底部设计有加强筋结构， 这些设计可以使塔体保持一定的形状和承受足够大的重量。 该塔体并不局 限于本实施例中所述的横流式冷却塔设备， 同样可以适用于其它各种类型 的方形冷却塔设备， 如逆流式方形冷却塔等。
本文中所述的玻璃纤维是一种复合材料， 学称纤维增强塑料（FRP)， 在国内习惯上被称为 "玻璃钢"。 它是以合成树脂为基体材料， 以玻璃纤维 及其制品为增强材料组成的复合材料。
