Super-clean and high-purity electronic grade hydrogen peroxide purification equipment

The utility model relates to an ultra-clean, high pure and electronic-level hydrogen peroxide purifying device, which mainly includes a feed tank, an intermediate tank, an absorption column, an exchange column, a product tank, a pure water tank and a cooling pump, wherein, the outlet of the feed tank is connected with the cooling pump that is connected with the inlet of the absorption column; the outlet of the absorption column is connected with the intermediate tank; a cooler is connected with the intermediate tank and the absorption column that is connected with the product tank; and the outlet of the pure water tank is connected with the inlets of the absorption column and the exchange column. The utility model uses the cooling pump to replace the traditional cooling water cycling technique, can strictly control the cooling temperature and offer highly stable hydrogen peroxide with less energy consumption and more environmental protection. In addition to a process-wide computer control and monitoring, the employment of polyvinylidene fluoride (PVDF) and automatic control and operating system can effectively prevent accidents and improve the safety.
