济宁圆型逆流冷却塔报价
为了节约能源,大型玻璃钢冷却水塔多用自然通风凉水塔,它由通风筒、人字柱、环基、淋水装置和塔心材料组成。通风筒多为钢筋混凝土双曲线旋转壳,具有较好的结构力学和流体力学特性。壳体下部边缘支承在等距离的V形或X形斜支柱上,以构成凉水塔的进风口。壳体的荷载经斜支柱传到基础上。基础多做成带斜面的环形基础以承受由斜支柱传来的部分环拉力,也可做成分离的单个基础或桩基础。通风筒的喉部直径小,当计算壳体受压稳定时,壳壁薄,由此向上直径逐渐增大构成气流扩散段,塔顶处设有刚性环,喉部以下按双曲线形逐渐扩大,下段壳壁也相应加厚,形成一个具有刚度的下环梁。通风筒也可做成截头锥壳或组合锥壳,或用钢构架外包木护板或石棉水泥护板的多边形塔筒。
圆形逆流式玻璃钢冷却塔,采用“瓶"形,风阻小。方形逆流式玻璃钢冷却塔整塔组装方便、坚固耐用、冷却效果好 。圆形逆流式冷却塔体由玻璃钢制作而成,表面胶衣采用原料,其色种内含光稳定剂,具有抗紫外线照射,色泽均匀鲜艳,可保持不褪色,不老化。传动部件采用逆流式冷却塔风机和电机。具有塔机运转平稳、匹配合理、风量大、能耗低、噪声小等特点。布水装置由玻璃钢布水管,尼龙布水器及铸铜内芯组成,通过水的反冲力,自动旋转布水。该布水装置压头损失小、所需水压低、配水均匀。填料经过测试,具有寿命长、冷效高、水的再分布均匀、风阻小、亲水性好、耐高温等特点。钢制构件采用的热浸镀锌工艺,外涂高性能防腐油漆,能确保其使用寿命。
选用及使用
就材料的耐寒性而言,但对于冷月平均低于—10℃的地区,订货时应提出要求防结冰措施,出厂前可配有淋水导流环,使水不流到百叶窗上。
循环水浑度不大于50毫克/升,短期不大于100毫克/升,不宜含有油污和机械性杂质,必要时采取灭藻及水质稳定措施。
本产品适用于不超过60℃。如超过60℃的,订货时提出,本厂可在选材上加以解决。如需阻燃型冷却塔,订货是须说明,也可满足要求。
150吨以上的冷却塔,风机叶片角度可以调整,但要保证各叶片角度,电流不超过电机的额定电流。各型风机可以短期间倒转来消冰。因此,在结冰严重的地区,应设置可逆磁力起动器,按钮应安装在冷却塔的附近。

按水和空气是否直接接触分:开式冷却塔:闭式冷却塔(也称封闭式冷却塔、密闭式冷却塔)。
其他型式冷却塔,如喷流式冷却塔、无风机冷却塔等。
优点
1、阻力小、冷却温差大:
由于WGFB塔的冷却元件(低压离心雾化装置)将水喷射成0.5mm微小雾滴,其比表面积远大于水被填料分散成膜状的比表面积,气水传热表面积大,且布水均匀,避免了填料老化变形及堵塞而产生的死区、沟流等导致冷却点温度分布不均匀现象,冷却效果优于填料塔
2、运行费用低,节能效果:
GFN低压雾化装置工作压力仅为0.035MPa,比水压自转式雾化装置工作压力0.2MPa低0.17MPa,配套水泵功率降低。WGFB塔系统阻力为填料塔的1/2左右,在冷却水量、风机相同时,配套电机功率降至填料塔的60%,节能效果,加之消除了清洗更换填料和布水喷头的费用,运行费用降低。
3、WGFB塔由于取消了填料,塔的系统阻力降至原来的1/2:
4、WGFB塔由于取消了填料,塔的系统阻力降至原来的1/2,在风机相同的情况下,由风机特性曲线可知,风量增至原来的1.2倍。气水比也增至原来的1.2倍,因此冷却温差较填料塔大2℃。
5、WGFB塔喷雾雾粒均匀、无堵塞、无维修、运行稳定可靠:
6、WGFB塔克服了填料塔填料老化、变形脆裂和布水喷头堵塞及冲落、填料脆片堵塞管道、泵和换热器等一系列影响塔和工艺系统设备性能的现象。
