Membrane element detection device for desalting water station and membrane element detection method

Abstract

The invention discloses a membrane element detection device for a desalting water station and a membrane element detection method. The detection device comprises a barrel, wherein the barrel is used for fixing a membrane element; one end of the barrel is connected with a water distribution room, and the other end of the barrel is connected with a water outlet pipe; the water distribution room is connected with a desalting water station water inlet pipe through a water inlet pipe. The detection method realizes off-line detection on the membrane element by utilizing the detection device. According to the invention, the performance condition of the on-line membrane element can be mastered through the off-line detection on the membrane element, so that the renewal expense of the membrane element is reduced, and energy conservation and consumption reduction are realized.

Description

technical field [0001] The invention relates to a desalted water station for production of cold-rolled sheets and silicon steel, in particular to a detection device and a detection method for a membrane element used in a desalted water station. Background technique [0002] At present, the iron and steel industry needs to use a certain amount of desalted water in the production process of cold-rolled sheets and silicon steel to prepare emulsions, etc. For this reason, iron and steel manufacturing enterprises generally design a desalination station to meet production needs. [0003] The main process flow of the silicon steel desalination station is: filtered water → raw water pool → raw water lift pump → laminated filter → plate heat exchanger → ultrafiltration device → ultrafiltration water production tank → ultrafiltration booster pump → adding scale inhibitor → Security filter→high-pressure pump→first-stage reverse osmosis (one stage and two stage)→intermediate water tank...

AI Technical Summary

Problems solved by technology

Therefore, in daily operation, fouling or clogging by foreign matter in the water inlet area of ​​the first and second membrane elements is very easy to occur, and once it occurs, it will affect the normal water production of the latter membrane elements, resulting in a decline in the water production of the entire group

Due to the high water pressure, long-term operation under this condition will cause the first and second membrane elements to burst, and the other membrane elements can be reused, but the specific conditions of the membrane elements cannot be judged in actual production, thus affecting desalination Water quality, but also affect the normal use of other membrane elements
