Processing technology of efficient heat exchange graphite heat exchanger
The invention relates to the technical field of graphite products, and particularly discloses a processing technology of an efficient heat exchange graphite heat exchanger, which comprises the following steps: S1, placing a graphite heat exchange block in hydroxyl silicone oil for preliminary dipping, and taking out graphite after dipping to prepare pretreated graphite; s2, a reinforcing filler is added into the hydroxyl silicone oil, the weight ratio of the hydroxyl silicone oil to the reinforcing filler is 1: (0.2-0.8), and a composite material is prepared through mixing; the pretreated graphite is placed in the composite material for secondary impregnation, the pretreated graphite is taken out after impregnation, and loaded graphite is prepared; s3, dipping the loaded graphite in the organic silicon modified phenolic resin liquid, taking out the loaded graphite after dipping, and performing cleaning, standing and curing to obtain a dipped graphite heat exchange block; and S4, the bottom cover serves as the bottom, graphite heat exchange blocks are sequentially stacked and impregnated on the bottom cover, then the shell is arranged in a sleeving mode, finally, a sealing head is added, sealing and fixing are conducted, and the graphite heat exchanger is manufactured. The graphite heat exchanger can exchange heat of high-temperature and high-pressure materials and has an efficient heat exchange effect.
本申请涉及石墨产品技术领域，具体公开了一种高效换热石墨换热器的加工工艺，包括如下步骤：S1、将石墨换热块置于羟基硅油中初步浸渍，浸渍后取出石墨，制得预处理石墨；S2、然后向羟基硅油中添加增强填料，羟基硅油与增强填料重量比为1:0.2‑0.8，混合制得复合料；将预处理石墨置于复合料二次浸渍，浸渍后取出预处理石墨，制得负载石墨；S3、将负载石墨置于有机硅改性酚醛树脂液中浸渍，浸渍后取出负载石墨，经清洗、静置、固化，制得浸渍石墨换热块；S4、以底盖为底，在底盖上依次堆叠浸渍石墨换热块，然后套设外壳，最后加上封头，密封固定，制得石墨换热器；使石墨换热器能够换热高温、高压的物料，并具有高效换热的效果。
