A hydrogen peroxide precise control dropwise adding reaction control system in a ferric phosphate preparation process

Abstract

The utility model discloses a hydrogen peroxide precise control drop reaction control system in the preparation process of iron phosphate, including the hydrogen peroxide tank and the reaction kettle through the pipeline connection, and is equipped with flow regulating valve and mass flowmeter on the pipeline between both, and mass flowmeter is controlled by DCS operation panel, and is equipped with the cumulative flowmeter on the feed pipe of reaction kettle, and the automatic valve is controlled by batch control instrument according to the cumulative flow of cumulative flowmeter, and then the flow regulating valve is controlled by automatic valve. The utility model discloses the automatic interlock control of hydrogen peroxide feed and ammonium dihydrogen phosphate ferrous solution feed through DCS control system, replaces manual operation feed, realizes hydrogen peroxide segmented type accurate drop feed, improves the utilization of hydrogen peroxide, and sets up material unloading mistake proof interlock on the unloading pipeline, prevents the product performance drop caused by hydrogen peroxide leak addition or unloading when the reaction is not completed.
