锦江化工液体烧碱溶解度伴热保温

信息来源:皖缆集团 浏览次数:2014 发布时间:2015-11-04

    电伴热带被用在液体烧碱的防结晶时,与其他行业中电伴热保温防冻的原理一致,只是它的温度要求相对高些。比如自来水管道的防冻保温,要求低温环境下不冻堵。所以,被伴热的介质(水)温度控制在0℃以上即可。采用电伴热的保温方式,一般会将温度控制在5到10℃。这样就能完全保证低温环境下不会被冻堵。
    当然,这里介绍的锦江化工烧碱项目实际案例中,不是为了防止管道中的液体烧碱结晶。而是应工艺的需求,提高液体烧碱的溶解度。烧碱是“氢氧化钠”的俗称,外观为片状或颗粒状的晶体;在20℃时,易溶于水,是一种较强腐蚀性的强碱。作为电伴热带厂家,虽然不能做到对每种化学物质性能的掌握;但是,我们要通过用户单位的技术介绍和应用要求,为其做好方案的准确设计,并经确认方可施工。

    电伴热带本身就具有工艺温度维持的功能,为了符合用户生产中的需求,我们在方案设计中,选用了并联式恒功率电伴热带。该电伴热带具有较强的耐腐蚀性和防爆、防静电性能,适合使用于用户的生产环境中;另外,根据用户提出的烧碱溶解度要求,需要将介质温度维持在60~70℃。根据现场使用环境,我们用了30W、40W、45W三种功率的伴热带,分别按照2根和4根平行铺设的方法。
    安装完成后,经过运行前的调试,可以正常工作,且完全达到了用户提出的各种要求。这个冬季,用户再也不会因达不到工艺温度需求而烦恼了,这正是我们电伴热带厂家为其服务的价值所在。
