AI Technical Summary
Existing solid hydrogen peroxide production equipment is costly and the reaction vessel is prone to caking, which affects production efficiency.
The system adopts a circulating structure. By connecting an external circulation pipeline to the outlet of the reactor and connecting a centrifuge to the mother liquor tank, the mother liquor is circulated back into the reactor for circulating reaction, reducing the number of reactor equipment and preventing the bottom of the reactor from caking when materials are added through the external circulation pipeline.
It reduces equipment costs and effectively prevents caking at the bottom of the reactor, thereby improving production efficiency and equipment utilization.
