Description
Technical field
The utility model is related to a kind of Recirculated cooling water treatment device, especially a kind of recirculated cooling water electric desalting apparatus,
Belong to Water Treatment in Circulating Cooling System field.
Background technology
Mankind's daily life be unable to do without water, and industrial production similarly be unable to do without water.With industrial development, water consumption
Increasing, have there is the phenomenon that insufficient water in many areas, therefore rationally have become developing industry with using water wisely and give birth to
A major issue in production.Industrial water mainly include boiler feed water, process water, water for cleaning and Municipal Sewage for Circulating,
Sewage etc..It is Municipal Sewage for Circulating that wherein water consumption is maximum, the dosage of recirculated cooling water account for enterprise water use total amount 50~
90%, the salt content raising of recirculated cooling water the inside can lead to problems such as heat transfer effect be deteriorated, pipeline scale is serious, seriously affect and follow
The normal operation of ring water system.
If industrial water is no before entering device systems to carry out sufficient desalting processing, as usage time increases
Long, moisture evaporation loss, the salinity of industrial water, which can be continuously increased, and then lead to impaired heat exchange efficiency, fouling, corrosion etc., asks
Topic.The recirculated water used in especially various pipelines, since recirculated water circulates in same pipeline for a long time, problem accumulation increases
The trend added is more obvious, if be pocessed not in time, is more prone to cause to seriously affect.Specifically：（1）Salinity increases
So that the heat conduction property of industrial water changes, it is gradually deviated from the normal operation range at the beginning of appliance arrangement design, is caused
Heat conduction efficiency reduces.（2）Salinity increase can also increase the fouling thickness of inner wall of the pipe, in these operations dirts for being formed for
The thermal coefficient of pipeline influences greatly, if cannot be cleared up in time, the operation energy consumption of appliance arrangement will be significantly
Increase.（3）The equipment that industrial water is in direct contact it after salinity increases will also result in great corrosiveness, mainly
Because after salinity increase, industrial water significantly improves the facilitation of equipment surface electrochemical corrosion, lead to corrosion speed
Rate is accelerated, and the metal ion being dissolved into water after electrochemical corrosion can further aggravate corrosion reaction.
In order to avoid industrial water is for the influence of middle salinity, the prior art is for various problem difference caused by it
Take corresponding specific aim processing, including addition antisludging agent, preservative, dispersant etc..Antisludging agent can subtract to a certain extent
The problem of fouling, occurs in use for slow industrial water so that and fouling occurs inside pipeline less or fouling does not occur, but
As time went on, antisludging agent gradually fails, the problem of still will appear inner wall of the pipe fouling.The effect of preservative is similar to resistance
Dirty agent can mainly delay the generation of etching problem, mitigate corrosion strength, but can not solve etching problem from the root cause.
The effect of dispersant as antisludging agent, preservative, be play dispersion industrial water in accumulation of impurities effect, delay impurity at
The destruction divided, but the above problem can not be eradicated.
In addition, the ratio of the additive component wherein used for the higher industrial water of salinity is bigger, and add various
Antisludging agent, preservative, dispersant etc. belong in itself increases additional chemical reagent composition into industrial water, these chemical reagent
Ingredient can equally be converted into pollution sources, objectionable impurities etc. after failure.
If industrial water can be carried out to sufficiently effective desalting processing, the problem of industrial water, will be delayed significantly
Solution, can be realized good industrial water quality requirements it is not necessary that chemical addition agent is largely added.There are some manufacturers to propose to adopt at present
The chemically treated method of electricity consumption carries out electrolysis processing to recirculated water, can contact hardness and carbonic acid in recirculated water to a certain extent
Salt, calcium and magnesium ion etc. reduce the root factor of fouling.But electrochemical treatments cost is higher, and treatment effeciency is relatively low, and electrification
It learns in electrolysis treated water or can have certain salinity impurity.
Then, also some manufacturers propose to handle using electro-desalting, and salinity and industrial water phase are driven using electric field action
Separation.But recirculated cooling water electric desalting apparatus is not accurate enough in the presence of extremely frequent and control at this stage, lacks effective pressure guarantor
Shield measure often occurs, due to the bad phenomenon of the operation such as damaged leak between film caused by hypertonia, not ensureing device
Operation steady in a long-term and effluent quality.
