Description
Technical field
The present invention relates to circulating cooling water purification field, more particularly to a kind of circulation of calcining furnace
The processing method and processing device of cooling water purification.
Background technology
Cooling circulating water is mainly used in factory, market, hospital etc. needs temperature controlled place, due to undressed
Water can cause tube wall and fouling of heat exchangers and burn into recirculated water bacterium algae to be grown, and cause production to be normally carried out, so needs are right
Water is processed.
Topmost processing mode is to add medicament in water to come antiscale, anti-corrosion, sterilization, algae removal at this stage.But medicament
Method brings many negative effects simultaneously：Waste water, power-consuming, environmental pollution, a series of problems, such as turn out drug tolerant bacteria.Therefore medicine
Agent method is makeshift, is not perfect processing method.Traditional chemical method mainly controls water to refer to using various medicaments
Mark, it is impossible to the impurity in water is taken out and contains phosphorus in draining, be also easy to produce eutrophication, accumulated impurities in water and increase, it is necessary to
Periodic replacement running water, waste water resource, secondly medicament is costly, increased production cost.
Traditional medicament method can only carry out continuous blowdown, cause substantial amounts of water resource waste, can using electro-chemical water facture
To reduce sewer 70%, water resource has been saved；It is phosphorous in traditional medicament method draining, eutrophication is also easy to produce, use electro-chemical water
Facture is free of any medicament, it is possible to achieve draining is pollution-free；Traditional chemical method must periodically carry out stopping production cleaning, pre-
Film, electrochemical process need not stop production cleaning, and the descaling rate of itself can reach more than 98%, Ca2+,Mg2+Etc. being deposited on pole plate,
More preferably, ion is stayed in water antiscaling effect, complexing, dispersion；Traditional medicament method needs substantial amounts of medicament expense, and electrochemical process only consumes
Electric 3kw/h；Traditional medicament method needs the management of the maintenance of medicament storage tank, medicine machine etc., drug delivery, storage, preparation etc., electricity
Chemical method only needs to Periodic scale removal.
Electro-chemical water treatment be electrolysis principle and polar water molecules with electrochemistry as theoretical foundation, the environmental protection for growing up
New technology.The effect that it not only reaches with chemical Treatment, additionally it is possible to scale removal, molten dirt, dissolve from pipeline into solid dirt,
Dissolved organic matter, water saving, energy-conservation, free of contamination new technology performance, are the directions of water process future development.
The content of the invention
The technical problem to be solved in the present invention is directed to the deficiencies in the prior art, there is provided one kind can reduce impurities in water product
Tired, dissolved organic matter simultaneously effective realizes the molten dirt of scale removal, while water saving, energy-conservation, free of contamination electrochemistry circulating water treatment side
Method；
In addition present invention also offers a kind of device of electrochemistry circulating water treatment.
Following technical scheme is used to solve the above-mentioned technical problem present invention：A kind of electrochemistry circulating water treatment method, bag
Include following steps：Cooling tower bottom is connected with second circulation water pump to side, and recirculated water is by second circulation water pump from cooling
Water tower enters filter, and subsequently into FEC electrochemical treatments main frames, last recirculated water incrustation scale is in FEC electrochemical treatments main frames
Adsorbed, the recirculated water after treatment is continued cycling through into cooling tower bottom cycle pond, and cooling tower bottom cycle water passes through
First circulation water pump enters heat exchanger from cooling tower bottom cycle pond, most enters cooling tower through heat exchanger afterwards.
A kind of electrochemistry circulating water treatment device, including cooling tower, cooling tower bottom are connected with first circulation water pump,
First circulation water pump is connected with heat exchanger by pipeline, and heat exchanger is connected by pipeline with cooling tower top；
The bottom of cooling tower is also associated with second circulation water pump, and second circulation water pump is connected with filter by pipeline, filtering
Device is connected with FEC electrochemical treatments main frames by pipeline, on the circulating water outlet of FEC electrochemical treatments main frames by pipeline with it is cold
But water tower bottom connection.
The present invention has following technique effect using such scheme：Reduce impurities in water to accumulate, notable dissolved organic matter,
The molten dirt of scale removal is simultaneously effective realized, while reach save water and energy, free of contamination effect；Traditional medicament method can only be arranged continuously
Dirt, causes substantial amounts of water resource waste, and sewer 70% can be reduced using the solution of the present invention, has saved water resource；Traditional medicine
It is phosphorous in agent method draining, eutrophication is also easy to produce, be free of any medicament using facture of the invention, it is possible to achieve draining is without dirt
Dye；Traditional chemical method must periodically carry out stopping production cleaning, pre- film, and the method for the present invention need not stop production cleaning, itself
Descaling rate can reach more than 98%, Ca2+,Mg2+Etc. being deposited on pole plate, more preferably, ion is stayed in water antiscaling effect, network
Splitting or integrating dissipates；Traditional medicament method needs substantial amounts of medicament expense, the method for the present invention only power consumption 3kw/h；Traditional medicament method needs medicine
The management of the maintenance of agent storage tank, medicine machine etc., drug delivery, storage, preparation etc., the method for the present invention only needs to periodically remove
Dirt；The calcium hardness for processing Posterior circle water is reduced to below 400mg/L by 440.74mg/L, and total hardness is reduced from 1381.33mg/L
To below 1100mg/L, total alkalinity is reduced to below 300mg/L by 335.22mg/L, and total Fe is reduced to by 0.33mg/L
Below 0.25mg/L, CI-Below 700mg/L is reduced to by 1051.39mg/L；RO membrane reverse osmosis concentrated water salt content is high, for following
Ring water system, can cause fouling, and this part concentrated water major part is discharged, by the way that after electro-chemical water treatment, concentrated water can be supplemented and followed
Ring water, reduces by a supplement for water, reaches the purpose of water saving.
