Description
Technical field
This utility model relates to a kind for the treatment of process of circulating cooling water, is specifically related at a kind of burning power plant cooling water
Reason system.
Background technology
In many chemical enterprises, the biggest for this part water yield of cooling system, usually account for enterprise and use
The 90%～about 95% of water inventory.At present, in the process of industrial colling, most enterprises are all by reclaiming circulation
Using, the amount of makeup water wherein cooling down water is about the 3%-4% of quantity of circulating water, and the 30% of amount of makeup water will be used for evaporative cooling,
Remainder will be recycled.
The make-up water of cooling water typically directly takes from river, river, lake water, or i.e. comes into operation after carrying out simple sand filtration, cold
But water is constantly concentrated during recycling and causes salinity to increase, and electrical conductivity rises, and also exacerbates corrosion and scaling
Tendency.Meanwhile, cooling water in use constantly contacts with surrounding, absorbs the dust in air and impurity, with
Time cooling tower in illumination, suitable temperature all antibacterial and algae will be grown generation facilitation.Corrosion will be led with fouling
Causing heat exchanger leakage quickly occurs and scraps, the glutinous mud formed that grows of antibacterial and algae makes resistance to water-flow increase, heat exchange
The heat transfer efficiency of device reduces, and equipment energy consumption increases.
For corrosion and scaling and the problem of glutinous mud, conventional processing method is to carry out by the way of adding chemical drugs
Prevention and delaying, reduces the salinity of recirculated water in the way of periodically draining the dense water of part simultaneously, dense by circulation
Demagnification rate maintains proper level.The drawback brought of chemical treatment method of cooling water is: fail essence by recirculated water
Contained salinity is removed, want to maintain suitable concentration rate and will not in water salinity too high, can only be by discharging the side of dense water
Formula, this mode not only causes the waste of water resource, causes the waste of chemical agent and the pollution to environment simultaneously.
At present, for corrosion and scaling and the problem of glutinous mud, have also appeared a kind of deeper circulating water treatment process,
I.e. remove the salinity in recirculated water by reverse osmosis process.The drawback of this method is the producing water ratio that the scale-forming ion in water is easily caused film
Decline, shorten service life and the waste of water resource of film.
Utility model content
In order to solve corrosion and scaling and the problem of foundry loam that recirculated water is in use brought, and chemistry dosing
Method, the drawback of conventional film facture, this utility model devises a kind of special system for burning power plant cold water process
System, this system is while solving above-mentioned drawback, it is achieved that " zero-emission " truly, improves the use of nucleus equipment
In the life-span, respond the policy of national green production, energy-saving and emission-reduction.

Via looping back Jellyfish pipe 15 and reverse osmosis produced water pump 16 is delivered to after heat exchanger carries out heat exchange, be recycled to cooling tower water tank.
RO device water for cleaning in this dedicated system, by RO water tank by RO water tank the first outlet pipe 17, RO flushing water pump
18, after cleaning filter filtration delivered to by cleaning filter the first water inlet pipe 19, enter RO device via RO the second water inlet pipe 20 and carry out clearly
Wash；Ultrafiltration apparatus in this dedicated system, demineralizer, more medium filter water for cleaning by ultrafiltration water tank by ultrafiltration water tank the
One outlet pipe 21 and rinse water delivery pump 22, ultrafiltration the second water inlet pipe 23, demineralizer the second water inlet pipe 24, more medium filter
Two water inlet pipes 25 are supplied to that ultrafiltration apparatus, demineralizer and more medium filter are counter to be cleaned.
In this dedicated system, the dense water of each device passes through more medium filter drain pipe 26, demineralizer drain pipe 27, video disc mistake
Filter drain pipe 28, ultrafiltration drain pipe 29, reverse osmosis drain pipe 30 collect, and wherein 17% stir for dry ash, and 21% uses
In place water, 23% is used for slag remover cooling water, and 39% enters clean Waste Water Treatment.Meanwhile, after place is rinsed
The dense water of draining and clean Waste Water Treatment converges into garden dope centralized processing system.
Profitable fruit of the present utility model is:
One, while this dedicated system solves system corrosion, fouling and the foundry loam problem that recirculated water easily causes, in fortune
Chemical agent need not be added during row, reduce the operating cost of circulating water treatment, also avoid the ring caused because of medicament
Environment pollution；
Two, the water yield that the amount of makeup water of this dedicated system is only walked by wind in cooling procedure and evaporator strip, and system
Backwash institute water requirement composition, amount of makeup water is about the 1.5-2.0% of recirculated water total amount.Because system need not be circulated outside dense water
Row, the dense water that the most each device collects will stir as dry ash, place water, slag remover cooling water use, and remain dense water and enter
Enter plant area's cleaning Waste Water Treatment.The clean dense water of Waste Water Treatment and plant area's flush discharge will enter at garden dope concentration
Reason system, therefore this dedicated system achieves " zero-emission " in the water yield and decreases the consumption of the municipal public use water yield.
Three, this dedicated system can fundamentally remove the salinity in recirculated water rather than by the way of outer draining desalination,
Ca in water2+、Mg2+、Cl-Plasma can make the concentration rate of system reach 8-12 on the premise of not producing corrosion and scaling tendency.
Four, for circulating water quality feature, this dedicated system is better than conventional embrane method and processes, and shows that its response rate can reach
75%, improve water-saving result, in system, the service life of reverse osmosis membrane can reach 3-5.
