Description
Technical field
A kind of method that the present invention relates to cleaning filter filter cloth.
Background technology
Filter is mainly used to solid-liquid separation, is widely used in chemical industry, pharmaceutical field.Fast development and city along with industry
The quickening of change process, increasing industry and mining waste water, sanitary sewage disposal industry are more and more flourishing, and the process of sewage is general all
Produce substantial amounts of mud therewith, thus need to separate mud with water, but industrially conventional means is entered to filter exactly.
The ultimate principle of filter is that mixed liquor flows through filter medium (filter cloth), and solid retention is on filter cloth.Fiber Materials pressed by filter cloth can
Being divided into two big classes, a class is natural fiber, such as cotton, hair, silk, flaxen fiber；Another kind of for chemical synthetic fiber, as terylene, nylon,
Polypropylene nitrile, modacrylic, aromatics poly-phenol amine, polyvinyl, acrylon, polyester fiber etc..
Filtration practice have shown that, in the use cycle of filter cloth, is often not dependent on the situation that filter cloth is worn, and is depending on
Blocked or contaminated speed.So how prevention alleviates the blocking of filter cloth and makes the filter cloth regeneration of blocking, is to filter cloth day
The great problem often safeguarded.
In existing filter cloth cleaning method, often directly rinse with clear water or rinsing with detergent immersion, be difficult to reach
To expected effect.
Summary of the invention
In view of this, the present invention provides a kind of filter cloth cleaning method, can thoroughly clean filter cloth.For solving above skill
Art problem, the technical scheme is that a kind of filter cloth cleaning method, it is characterised in that comprise the following steps:
A. wash；Dry；
B. pickling；After pickling with clear water rinse to pH value be 7；Dry；
C. alkali cleaning；After alkali cleaning with clear water rinse to pH value be 7；Dry；
D. organic solvent soaks；
E. steam blast；
F. dry standby.
Improve as one, in step A, first water for cleaning is heated to 75-80 DEG C, then by giant to filter cloth
It is rinsed；Flush sequence is for first rinsing reverse side, then rinses front.
Improving as one, in step B, acid washing method is as follows: prepares container, and adds water to 3/4ths in container；Past
Acid is added in container；In acid solution, it is passed through steam heated by acid solution；Filter cloth is put in hot acid solution and soak.
Preferred as one, in step B, described acid is hydrochloric acid, and the concentration of acid solution is 1.5%-2%, hot acid solution's
Temperature is 60-70 DEG C, and soak time is 50-70 minute.
Improving as one, middle alkali washing method is as follows: prepares container, and adds water to 3/4ths in container；Toward container
Interior addition alkali；In aqueous slkali, it is passed through steam be heated to by aqueous slkali；Filter cloth is put in hot alkaline solution and soak.
Preferred as one, in step C, described alkali is sodium hydroxide, and the concentration of aqueous slkali is 1.5%-2%, and thermokalite is molten
Temperature be 70-80 DEG C, soak time is 50-70 minute.
Improve as one, step D utilizes organic solvent soak 25-35 minute.
Preferred as one, the organic solvent in step D is acetone.
Improve as one, in step E, filter cloth is tiled and on drying frame, and utilizes saturated vapor to enter below filter cloth
Row hydro-peening；The hydro-peening time is 10-20 minute.
The invention have benefit that: there is the filter cloth cleaning method of above-mentioned steps, it is possible to thoroughly clean filter cloth.Its behaviour
Make simple, flow process is short, without extra labour cost operating cost, water consumption greatly reduces, and effect is obvious.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that technical scheme, below in conjunction with detailed description of the invention
The present invention is described in further detail.
The present invention comprises the following steps:
A. wash；First water for cleaning is heated to 75-80 DEG C, then by giant, filter cloth is rinsed；Rinse
Order is for first rinsing reverse side, then rinses front.Owing to the solids after filtering is deposited in filter cloth front mostly, so that rinses is suitable
Sequence should start from the negative, utilizes the water column of high pressure that filter cloth produces impact concussion so that the solids on filter cloth comes off.If
First if front starts to rinse, solids is easily allowed to be difficult to remove in being stuck in the mesh of filter cloth.After rinsing, filter cloth is dried.
B. pickling；Prepare container, and add water to 3/4ths in container；Hydrochloric acid is added so that hydrochloric acid is molten in container
The concentration of liquid is 1.5%-2%；In acid solution, it is passed through steam acid solution is heated to 60-70 DEG C；Filter cloth is put into hot acid molten
Liquid soaks 50-70 minute.Rinse general 5 minutes with clear water after pickling, after flushing, utilize PH reagent paper to test, to pH value
Till being 7；Dry subsequently.The purpose of pickling is inorganic salt, the metal-oxide etc. removing in filter cloth.
C. alkali cleaning；Prepare container, and add water to 3/4ths in container；Sodium hydroxide is added so that alkali in container
The concentration of solution is 1.5%-2%；In aqueous slkali, it is passed through steam aqueous slkali is heated to 70-80 DEG C；Filter cloth is put into thermokalite
Solution soaks 50-70 minute.Rinse general 5 minutes with clear water after alkali cleaning, after flushing, utilize PH reagent paper to test, to PH
Till value is 7；Dry subsequently.The purpose of alkali cleaning is to remove the Organic substance in filter cloth and colloid.
D. organic solvent soaks；Utilize acetone soln that filter cloth is soaked 25-35 minute.For thoroughly dissolving having in filter cloth
Machine thing.
E. steam blast；Filter cloth is tiled and on drying frame, and utilizes saturated vapor to carry out hydro-peening below filter cloth；Hydro-peening
Time is 10-20 minute.For evaporating the acetone on filter cloth.
F. dry standby.Can be by the way of dry in the sun, it is also possible to by the way of heating.
