具体实施方式 detailed description
下面参考附图和优选实施例，对本实用新型技术方案作详细说明。 The technical scheme of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
对于大型的双塔及多塔连体结构的冷却塔来说，由于下部空间较大，适当加大受风量，可提高冷却效率，顶底复试机械通风适宜双塔及多塔结构。 For large-scale cooling towers with double towers and multi-tower conjoined structures, due to the large lower space, appropriately increasing the air volume can improve cooling efficiency, and the top-bottom retest mechanical ventilation is suitable for double-tower and multi-tower structures.
如图4所示，是本实用新型中顶底复式机械通风冷却塔的结构示意图。 As shown in Figure 4, it is a structural schematic diagram of the top-bottom compound mechanical ventilation cooling tower in the utility model.
顶底复式机械通风冷却塔的结构包括第一冷却塔单元和第二冷却塔单元，第一冷却塔单元和第二冷却塔单元的外壳1内部设置有收水器2、配水管路3和淋水填料4，收水器2、配水管路3和淋水填料4固定在外壳1的内部空间，配水管路3位于淋水填料4上部，收水器2位于配水管路3上部；第一冷却塔单元和第二冷却塔单元的外壳1顶部分别设置有第一出口风筒41和第二出口风筒43，第一出口风筒41内部设置有第一出口风机42，第二出口风筒43内部设置有第二出口风机44；第一冷却塔单元的外壳1的侧壁上设置有入口风筒45，入口风筒45连通第一冷却塔单元和第二冷却塔单元内淋水填料4的下部空间，入口风筒45内部设置有入口风机46。配水管路3相连接有喷头。 The structure of the top-bottom compound mechanical ventilation cooling tower includes a first cooling tower unit and a second cooling tower unit. The shell 1 of the first cooling tower unit and the second cooling tower unit is provided with a water eliminator 2, a water distribution pipeline 3 and a shower. The water filler 4, the water eliminator 2, the water distribution pipeline 3 and the water sprinkling filler 4 are fixed in the inner space of the shell 1, the water distribution pipeline 3 is located on the upper part of the water sprinkling filler 4, and the water eliminator 2 is located on the upper part of the water distribution pipeline 3; the first The shell 1 tops of the cooling tower unit and the second cooling tower unit are respectively provided with a first outlet air cylinder 41 and a second outlet air cylinder 43, the inside of the first outlet air cylinder 41 is provided with a first outlet fan 42, and the second outlet air cylinder 43 is provided with a second outlet fan 44 inside; the side wall of the shell 1 of the first cooling tower unit is provided with an inlet air duct 45, and the inlet air duct 45 communicates with the first cooling tower unit and the second cooling tower unit. The lower space of the inlet air duct 45 is provided with an inlet fan 46 inside. The water distribution pipeline 3 is connected with a sprinkler head.
收水器2的作用是在热空气排出冷却塔之前回收部分水滴，以减少冷却水的损失。 The function of the water eliminator 2 is to recover part of the water droplets before the hot air exits the cooling tower, so as to reduce the loss of cooling water.
淋水填料4由大量的波浪形轻质耐腐材料片组成。淋水填料4将下部进风区与上部蒸发区分隔，对空气进入有很大的阻隔，避免了下部回风气流与 上部蒸发气流互相干扰，也避免了水滴的吹散损失。 The water spray filler 4 is made up of a large number of corrugated lightweight anti-corrosion material sheets. The water spray filler 4 separates the lower air intake area from the upper evaporation area, which has a large barrier to air entry, avoids mutual interference between the lower return air flow and the upper evaporation air flow, and also avoids the blowing loss of water droplets.
为防止杂物被风机吸进塔内，引导空气均匀分布于顶底复式机械通风冷却塔内部的整个截面上，入口风筒45内部设置有百叶窗和波形导风板，百叶窗和导风板是空气分配装置，分别设置在入口风机46两侧，百叶窗设置在入口风机46的外侧，波形导风板设置在入口风机46的内侧。为防止入口风筒45内的入口风机46运转时产生局部涡流和通风死角，入口风机46可略有一定上仰倾角。 In order to prevent sundries from being sucked into the tower by the fan, and guide the air to be evenly distributed on the entire cross-section inside the top-bottom composite mechanical ventilation cooling tower, the inlet air duct 45 is provided with louvers and wave-shaped wind deflectors inside, and the louvers and wind deflectors are air The distribution device is arranged on both sides of the inlet fan 46 respectively, the louvers are arranged on the outside of the inlet fan 46 , and the corrugated wind deflector is arranged on the inside of the inlet fan 46 . In order to prevent the inlet blower 46 in the inlet air cylinder 45 from producing local eddy currents and dead angles of ventilation, the inlet blower 46 can have a certain upward inclination angle.
第一出口风机42、第二出口风机44、入口风机46采用轴流式风机，具有风量大、风压适宜、噪声低、防腐蚀、防潮、全封闭等特点，入口风机46要求低转速、低动能。由于双塔及多塔结构是长方体，在外壳1外侧安装风筒及风机(第一出口风机42、第二出口风机44、入口风机46)，既能有效利用长度空间加大进风量，又不会吹散水滴，损失水量。对于单塔结构来说，进风量不好控制。 The first outlet fan 42, the second outlet fan 44, and the inlet fan 46 adopt axial flow fans, which have the characteristics of large air volume, suitable wind pressure, low noise, corrosion resistance, moisture resistance, and fully enclosed. The inlet fan 46 requires low speed and low speed. kinetic energy. Since the double-tower and multi-tower structures are rectangular parallelepipeds, air ducts and fans (the first outlet fan 42, the second outlet fan 44, and the inlet fan 46) are installed on the outside of the housing 1, which can effectively use the length space to increase the air intake without The water droplets will be blown away and the water volume will be lost. For a single tower structure, the air intake volume is not easy to control.
降温原理是，喷头喷下的热水滴与冷空气接触时，一方面与冷空气直接传热，另一方面由于水蒸气表面和空气存在压力差，在压力作用下，产生蒸发现象，将水中热量带走，达到降温目的。不论是双塔结构还是多塔结构的顶底复式机械通风冷却塔，淋水填料4下方的空气分配区都相互贯通，冷空气经入口风机46鼓吹后由入口风筒45依次进入第一冷却塔单元、第二冷却塔单元下方；在第一冷却塔单元和第二冷却塔单元顶部第一出口风机42、第二出口风机44抽吸作用下，冷空气经淋水填料4与热水接触后形成热空气，再通过配水管路3和收水器2由第一出口风筒41和第二出口风筒43排出。 The principle of cooling is that when the hot water droplets sprayed by the nozzle contact with the cold air, on the one hand, it directly transfers heat to the cold air; Take it away to achieve the purpose of cooling down. No matter it is a double-tower structure or a multi-tower structure top-bottom compound mechanical ventilation cooling tower, the air distribution area under the water spray filler 4 is connected to each other, and the cold air is blown by the inlet fan 46 and then enters the first cooling tower through the inlet fan 45 in turn. unit and the second cooling tower unit; under the suction of the first outlet fan 42 and the second outlet fan 44 on the top of the first cooling tower unit and the second cooling tower unit, the cold air passes through the water spray filler 4 and contacts the hot water The hot air is formed, and then is discharged by the first outlet air cylinder 41 and the second outlet air cylinder 43 through the water distribution pipeline 3 and the water eliminator 2 .
由于空气流速增大，空气吹动水滴使水滴发生一定雾化，在横流冷却与逆流冷却两个过程中，热水滴与干燥的冷空气接触时间更长，更充分，带走热量也更多。 As the air velocity increases, the air blows the water droplets to make the water droplets atomize to a certain extent. In the two processes of cross-flow cooling and counter-flow cooling, the contact time between hot water droplets and dry cold air is longer and more sufficient, and more heat is taken away.
