Background

In the chemical production process, chemical waste residues are often produced, and the chemical waste residues are mainly solid, semisolid or mud-like waste formed by materials which do not participate in the reaction or run off, sediments produced by the reaction and the like. Since the chemical waste residue is separated from the prepared liquid (chemical liquid medicine), the common separation means is to pass the liquid containing the chemical waste residue into a sedimentation tank in a natural sedimentation mode, and after a period of natural sedimentation, the separation of the liquid and the chemical waste residue is realized. The separation means is long in time consumption and low in efficiency.

At present, the most economical and effective means is to fix a filter screen in a liquid discharge pipe of a reaction vessel, and when liquid containing chemical waste residues passes through the filter screen in the liquid discharge process, the chemical waste residues are trapped by the filter screen to realize separation from the liquid. However, over time, chemical waste residues can increasingly accumulate or accumulate on the inner side of the filter screen, and cause blockage, thereby affecting normal liquid discharge.

Therefore, a back flushing method is usually adopted, namely clear water or the same liquid reversely rushes through the filter screen, so that the purposes of cleaning waste residues and avoiding blockage are achieved. However, if the back flushing is performed by using clear water, although the clear water is discharged together with the chemical residues, the clear water inevitably remains in the liquid discharge pipe, so that the liquid is polluted to a certain extent; if the same liquid is adopted for back flushing, the liquid can be discharged together with chemical dregs, and the waste of materials can be caused to a certain extent.
