Abstract

The invention discloses an ammonium phosphate slurry pipeline compound dredge method which includes a first step of installing a dredging device, wherein a flange mounting seat is arranged on an opening of the tail end of a pipeline for producing ammonium phosphate slurries, a flange plate is fixed on the flange mounting seat, and the dredging device is supported on the flange plate, a second step of spraying cleaning media, wherein a portion, located inside the pipeline, of the dredging device can carry out spraying of the cleaning media on the inner wall of the pipeline, and the cleaning media soaked with the dissolving slurries can dissolve scale layers on the inner wall of the pipeline, and a third step of carrying out dredging, pushing a dredging rod in the process of spraying the cleaning media, and enabling a cleaning disc to move to clean the inner wall of the pipeline. Through the method, the pipeline does not need to be dismantled, and workers can carry out on-line dredging on the clogged pipeline, so the ammonium phosphate slurry pipeline compound dredge method can greatly reduce labor intensity of the maintenance workers, improves working efficiency, reduces safety risks in the operation process of the maintenance workers, shortens down time, and improves on-stream rate.

Description

technical field [0001] The invention belongs to the technical field of ammonium phosphate production, and in particular relates to a compound dredging method for ammonium phosphate slurry pipelines. Background technique [0002] In the slurry method ammonium phosphate production process, the neutralized ammonium phosphate slurry, especially the ammonium phosphate slurry that has been concentrated step by step, has lower and lower moisture content, increasing viscosity and poor fluidity. , Frequent blockage of pipelines by ammonium phosphate slurry resulted in unsustainable and stable production. Especially in recent years, it is extremely difficult to purchase high-grade phosphate rock. The use of low-grade phosphate rock dominates, and the impurity content is getting higher and higher. As a result, the ammonium phosphate slurry is more likely to scale on the inner wall of the pipeline, and the diameter of the pipeline gradually becomes smaller. This aggravates the occurren...
