Washing (high temperature hydrolysis method) of melt filter (high temperature hydrolysis method) is divided into three steps: The first stage is a hydrolysis phase, and the second stage is a pre-oxidation phase, and the third stage is the oxidation stage. The purpose of the melt filter wash is to make the dirty candle filter element as few residues as possible. For the next - step TEG cleaning and alkaline washing. The self-cleaning of the melt filter is divided into 3 large Steps: hydrolysis, pre-oxidation, oxidation, hydrolysis, and pre-oxidation These two steps are divided into two phases. The control temperature of each stage is different.
The function of melt filter: The main function of the melt filter is to remove impurities, agglomerates, and other --like contaminants in the melt in the production process. To make a uniform uniform melt through the melt filter Degree and pureness, the candle filter core of different filtration results is required according to different product requirements.
