Back flushing system and back flushing method

Abstract

The invention provides an underflow pump back flushing system capable of efficiently operating and a back flushing method, and is used for performing back flushing and cleaning on a ceramic filter. The back flushing system comprises a back flushing pool, a back flushing pipeline, an underflow pump, a spare pipeline, a sewage pump and a sewage pipeline, wherein the back flushing pipeline is connected between the back flushing pool and the underflow pump; a pumping pipeline outlet of the underflow pump is connected to the ceramic filter; a pumping pipeline outlet of the sewage pump is connected to the sewage pipeline; the spare pipeline is connected between the sewage pipeline and the back flushing pipeline. The back flushing method based on the back flushing system disclosed by the invention keeps the cleaning of the ceramic filter free from influence of water source supply and prevents the cleaning from being interrupted; the operating efficiency of operator can be improved, and simultaneously the normal production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of liquid material pipeline transportation, in particular to an underflow pump backwash water system and a backwash water method. Background technique [0002] The existing ceramic filter needs to be cleaned by recoil water in real time during work. The existing underflow pump recoil water system is as attached figure 1 As shown, it includes an underflow pump 5 and a backwash water pipeline 6. The backwash water used comes from the collection tank 3 supplied by the horizontal pump 1 and the clean water tank 4 supplied by the clean water pump 2 respectively, the collection tank 3 and the clean water The pool 4 is connected to the backflush water pipeline 6, the water outlet end of the backflush water pipeline 6 is connected to the underflow pump 5, and the pumping output end of the underflow pump 5 is connected to the ceramic filter to clean the ceramic filter with backflush water. The backflushing water sys...

AI Technical Summary

Problems solved by technology

The backflushing water system in the prior art has the following disadvantages: in the actual operation process, if the horizontal pump and the clean water pump are damaged, repaired and replaced, or the water quality of the clean water tank and the collection tank is seriously polluted, it cannot Water is supplied to the backflush water pipeline in time, and the underflow pump cannot clean the ceramic filter with backflush water, resulting in the shutdown of the entire production system, which seriously affects the normal production needs. Therefore, the operation of the underflow pump backflush water system in the prior art The stability is poor, and it cannot meet the uninterrupted backwash water cleaning requirements for ceramic filters
