Column type membrane leakage detection repair equipment and leakage detection repair method

Abstract

The invention discloses column type membrane leakage detection repair equipment, which includes a liquid inlet main pipe, an air inlet main pipe and a drainage main pipe. The liquid inlet main pipe is communicated with multiple liquid inlet branch pipes. The center of each liquid inlet branch pipe is communicated with the air inlet main pipe through an air inlet branch pipe. The bottom of each liquid inlet branch pipe is communicated with the drainage main pipe through a drainage branch pipe. The bottom of each liquid inlet branch pipe is communicated with a lower seal box of a to-be-detected column type membrane. Each liquid inlet branch pipe is correspondingly provided with a fixation platform for fixing the to-be-detected column type membrane. Each of the liquid inlet branch pipes, the air inlet branch pipes and the drainage branch pipes is provided with a switch valve. Additionally, the invention also provides a column type membrane leakage detection repair method. According to the method, the original mode of simultaneous pressing by 4 membrane columns is changed into single column pressing, and employs independent control, so that continuous operations on multiple column type membranes can be realized. Also, pressing leakage repairing and immersion drip spraying are changed into one process, so that after pressing leakage repairing, protection liquid immersion and drip spraying are no longer needed. Thus, production efficiency of the column membrane is greatly improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of water treatment equipment manufacturing, and relates to a column membrane leak detection and repair equipment and a leak detection and repair method. Background technique [0002] In order to ensure the pass rate of the column membrane and facilitate product storage, a process that can quickly detect the defects of the column membrane and effectively soak the membrane filament protection solution is urgently needed. The original process is to repair after pressing and testing on the pressing car, and then apply protective liquid to the membrane filaments by static immersion. In this process, 4 column membranes are tested at the same time each time before replacing other membranes. The column membrane is used for pressure detection, the pressure efficiency is low, the process is more, the waste of protective liquid is large, the cost is high, and the product quality is difficult to guarantee. And there are deficien...
