BR0.15型板式热交换器

    采用化学清洗板式热交换器时,要根据实际请况和水质的不同所结垢的垢质进行分析化验分别配制药剂清洗。由于清洗的困难程度是随着垢层厚度或沉积的增加而迅速增大的,所以清洗间隔时间不宜过长,应根据生产装置的特点,换热介质的性质,腐蚀速度及运行周期等情况定期进行检查,修理及清洗。

    根据换热器的形式,应在换热器的两端留有足够的空间来满足条件(操作)清洗、维修的需要。固定管板式换热器在安装时,两端应留出足够的空间以便能抽出和更换管子。并且,用机械法清洗管内时,两端都可以对管子进行刷洗操作。浮头式换热器的固定头盖端应留有足够的空间以便能从壳体内抽出管束,外头盖端必须也留出一米以上的位置以便装拆外头盖和浮头盖。U形管式换热器的固定头盖应留出足够的空间以便抽出管束,也可在其相对的一端留出足够的空间以便能拆卸壳体。

 

Using chemical cleaning, according to the different actual conditions and water quality, please scale scale by qualitative analysis assay preparation medicament cleaning, respectively.Due to the difficulty of cleaning degree is increased with the increase of scale or sedimentary layer thickness increased rapidly, so the cleaning interval time shoulds not be too long, should according to the characteristics of the production plant, the nature of the heat transfer medium, the corrosion speed and operation cycle, and so on and so forth on a regular basis for inspection, repair and cleaning.According to the form of heat exchanger, with sufficient space should be at both ends of the heat exchanger to meet the needs of the conditions (operations) cleaning and maintenance.Both ends of fixed tube plate heat exchanger in the installation, should set aside enough space so that it can take out and replace the pipe.And, by using the mechanical method cleaning tube, both ends can be scrubbing operation of pipe.Fixed epicranium end of floating head heat exchanger should have enough space to bundle, "from the casing outside the cranium end must also set aside more than a metre of location to casual split cranium and floating head cover.Fixed cranium of u-tube heat exchanger should set aside enough space to take control, also can be in one end of its relative to set aside enough space so as to remove the shell.
