One, technical field
What the present invention relates to is a kind of water separating membrane treatment technology, specifically a kind of membrane component clean-out system device for evaluating performance and evaluation method thereof.
Two, background technology
In the occasion of utilizing membrane technology to carry out water treatment, owing to include compositions such as various salts, metal oxide, colloid, suspension and microorganism in the water of need handling, in the operational process, the side that these compositions are trapped within film causes the pollution to membrane component.Polluter stops up the micropore water-permeable passage of membrane component, and its result reduces the water permeability of film, and former water wall pressure increases with energy consumption and increases.In order effectively to utilize the water separating membrane treatment technology, must use clean-out system that membrane component is cleaned often, remove the polluter on the membrane component micropore, guarantee the stable operation of water separating membrane treating apparatus.Selling in the market has various membrane component clean-out systems, and the user purchases often and just directly applies to production, if clean-out system inferior directly influences the cleaning performance of membrane component, gets frequent clean or changes membrane component, not only loses time but also increase cost.And, do not see the evaluation method of effective evaluation clean-out system performance now also not at the evaluating apparatus of laboratory stage acquisition clean-out system technical feature yet.
Three, summary of the invention
Technical matters to be solved by this invention provides a kind of membrane component clean-out system device for evaluating performance and the evaluation method thereof that can judge clean-out system performance quality, so that the clean-out system that selection has the optimal clean performance.
Realize that the technical scheme that purpose of the present invention adopts is: membrane component clean-out system device for evaluating performance mainly is made up of water tank, water pump, filtrator, pipeline, pressure vessel, thermometer, tensimeter, flowmeter and valve; Water pump is by pipe water mouth termination water tank, water outlet end is taken over filter, the other end of filtrator joins by being connected to thermometer and manometric pipeline and pressure vessel on it, the outlet water outlet end of pressure vessel is connected to away the pipeline of water purification respectively and walks the pipeline of dense water, be connected to flowmeter and valve on two pipelines, walk the pipeline other end water flowing case of water purification or the water pipe that runs in, walk the logical dense water tank of the other end of the pipeline of dense water.Thereby set up dynamic recycle to extinction system.
Using the method step that this membrane component clean-out system device for evaluating performance carries out clean-out system performance evaluation is:
(1), selects then clean-out system or preparation clean-out system;
(2), in water tank, add test water, install contaminated membrane component in the pressure vessel, start membrane component clean-out system device for evaluating performance, design temperature, pressure determine flow velocity;
(3), in water tank, add clean-out system in the test water, start membrane component clean-out system device for evaluating performance, design temperature, pressure determine flow velocity;
(4), according to adding the variation that the mutation analysis of flow velocity goes out membrane flux before and after the clean-out system, according to the mutation analysis degree of cleaning of test back water quality, analysis-by-synthesis is estimated out the cleaning performance of clean-out system again.
The invention has the beneficial effects as follows: by using membrane component clean-out system device for evaluating performance, in the laboratory, carry out screening and assessment fast, estimate out the technical feature of clean-out system, determine the cleaning performance and the range of application of clean-out system, select suitable clean-out system and be used to produce thoroughly clean that membrane component is cleaned.Thereby reduced the wash number of membrane component, prolonged the serviceable life of membrane component, reduced production cost, improved economic benefit.
