Graphite anti-oxidation impregnation method for heat exchanger
The invention discloses a heat exchanger graphite anti-oxidation impregnation method, and relates to the technical field of heat exchanger graphite, the heat exchanger graphite anti-oxidation impregnation method comprises the following steps: 1, impregnation, 2, raw material processing, 3, drying, 4, high temperature curing, 5, connection, 6, pipe processing, and 7, high temperature curing again. According to the method, the temperature is increased according to a temperature increasing curve, the temperature increasing rate is 8-12 DEG C/h, the temperature increasing time is longer than 30 hours, generally 30-36 hours, and the temperature is 330-800 DEG C, so that high-temperature curing is carried out on the graphite, the existing short pipe can be utilized, and the old heat exchange pipe can be repaired and utilized; according to the method disclosed by the invention, the short tube and the old heat exchange tube are put into use again after being subjected to drying, dipping, high-temperature curing, connection and high-temperature curing, so that the effects of saving energy and reducing consumption are achieved, and the problems that resources are wasted when graphite is processed or replaced, and waste liquid or waste gas is generated in the dipping process are solved.
本发明公开了一种换热器石墨抗氧化浸渍方法，涉及换热器石墨技术领域，该换热器石墨抗氧化浸渍方法，包括以下步骤：步骤一：浸渍，步骤二：原料加工，步骤三：烘干，步骤四：高温固化，步骤五：连接，步骤六：管材加工，步骤七：再次高温固化同步骤。本发明通过按照升温曲线升温，升温速率是8‑12°C/h，时间大于30小时，一般为30‑36小时，温度330°C‑800°C从而对石墨进行高温固化，还可以通过利用已有的短管和修复利用旧的换热管结合，利用本发明的方法将短管和旧的换热管经烘干、浸渍、高温固化、连接、高温固化后再次投入使用，达到节省能源降低消耗的效果，解决了石墨在进行加工或者替换的时候导致资源浪费，而且浸渍过程中产生废液或废气的问题。
