半即热式浮动盘管换热器

                                          半即热式浮动盘管换热器

概述

热水系统广泛地应用于宾馆、工厂、医院、浴池等各种场合。其热水通常由汽－水换热器来加热。长期以来，人们广泛地采用了储存加热器(管壳式换热器)，但这种加热器体积过大，并且加热缓慢，其温度的精确控制困难。因此，这种加热器能源消耗高，空间要求大，结构复杂、易生水垢、清洗困难、热效率不高。基于这种原因，本公司开发了新的换热设备SJD系列浮动盘管换热器。这种热交换器具备最新的换热元件，使换热体积很小，与螺旋板式相比。热效率提高了20%，热交换率高达99%，可以自动清除脆性水垢，维修方面。

结构原理

   SJDB半即热式浮动盘管换热器主要由支座、壳体、换热盘管及各种接口组成，其核心部件--换热盘管采用紫铜管径先进的生产工艺加工成双螺旋盘管结构，换热盘管与干管(热媒进出管)采用螺纹联接，便于拆卸维护。壳体内设有挡流和混流组件。
THPB半即热式浮动盘管换热器壳程为被热水管程为热媒(蒸汽、高温热水等)，热媒在干管的引导入，均衡流入每个换热盘管，由于管程流通面积小，热媒以较高的速度流动，推动盘管低幅度高频振动，扰乱换热管与液体间的层流传热层，强化对流换热。同时，供水设备生产厂家被加热水依次经过换热管加热，并且在挡流和混流组件的引导下均匀流出。
由于换热盘管高频振动，水垢不易趋附管壁，即使有部分积垢，也很容易脱落，并且可利用铜与水垢热胀缩性的显著差异，采用热冲击方法将积垢清除。
SJD浮动盘管换热器壳体材质为碳钢或不锈钢，换热管材质为紫铜。订制特别材质、换热面积和工作压力等级的浮动盘管换热器。

性能特点

SJDB半即热式浮动盘管换热器采用新式结构，较传统容积式换热器优点突出：
传热系数高：独特的高频振动，破坏了常规换热时的层流换热层，改善了传热方式，传热系数大大提高。THPJ型换热器传热系数达2600~4000W/m2·℃(汽水换热)和1800~3000W/m2·℃(水水换热)。
防垢、除垢：换热盘管高频振动，不易积垢，即使有积垢，由于积垢的导热能力差，热胀缩性能远不如铜，很容易在热应力的作用下自行脱落。
节能：由于具有较高的传热系数，使得热量传递易于进行，热媒出水温度低，充分利用热能，减少了能源消耗，并使得低温热能能够得到适当利用。
水头损失小：壳程为大空间流体，阻力损失≤3KPa，管程为多个换热盘管并联，阻力损失≤10KPa。
安装维护方便：严格按照国家规范制造；换热盘管可取出维护，安装时只须用地脚螺栓固定在基础上即可。
