A kind of soften water treatment process

[technical field]

The present invention relates to softening water process field, especially relating to a kind of for carrying out pretreated soften water treatment process to hot water boiler water-feeding.

[background technology]

Known, because hot water boiler is the heat-exchange equipment producing steam or hot water, and water is the heat transferring medium of boiler, therefore, hot water boiler water-feeding water quality quality, for hot water boiler safe operation, energy consumption and have vital impact work-ing life; For guaranteeing the water quality of hot water boiler water-feeding, supplementary feed used in actual applications is all not only adopt well water at present, and usually also to carry out sofening treatment to well water, then just the well water after softening is inputed to hot water boiler, the flow process of its soften water treatment process is as follows: well water--tank--boosting pump--water supply network--y-type filter--full-automatic softening agent--softening water tank--hot water boiler; But find in long-term practical application, existing soften water treatment process has following defect: 1, effluent quality is unstable, water outlet sometimes also has defective phenomenon; 2, when the later stage carries out resins exchange removal calcium ions and magnesium ions by sodium bed, very easily pollute resin, thus cause significantly be reduced to 6 ~ 8 months by normal more than 5 years the work-ing life of resin, this directly causes user to increase production cost because of supplementary amount of resin; 3, the operating pressure fluctuation due to water softening system is larger, between 0.2 ~ 0.7MPa, and the normal operating pressure of system is between 0.25 ~ 0.3MPa, therefore, pressure surge causes more greatly melded system to run flow velocity fluctuation, thus causes effluent quality to fluctuate, simultaneously, because overvoltage causes mechanical fatigue to be inclined to glass reinforced plastic interchanger body, and then the corresponding staff of adding frequently adjusts the working strength of pressure.

[summary of the invention]

In order to overcome the deficiency in background technology, the invention discloses a kind of soften water treatment process, the water quality after described technique is softened is qualified stable, and this technique can also effectively avoid resin contaminated when carrying out sofening treatment simultaneously.

For achieving the above object, the present invention adopts following technical scheme:

A kind of soften water treatment process, described technical process is as follows: well water--tank--boosting pump--water supply network--raw water box--raw water pump--more medium filter--activated charcoal filter--y-type filter--full-automatic softening agent--softening water tank--hot water boiler.

Further, described raw water pump requires to exert oneself as 30m3/h, lift are 28 ~ 34m.

Further, use two raw water pumps in described technique, operation scheme is the using and the reserved.

Further, under described more medium filter separate unit, water reaches more than 72 hours, runs flow velocity <10m/h.

Further, described more medium filter is the vertical more medium filter of diameter 2000mm, and separate unit is exerted oneself 30m3/h, and run flow velocity 9.55m/h, back flushing flow velocity is 34 ~ 49m/h.

Further, described activated charcoal filter runs flow velocity <10m/h.

Further, described more medium filter is provided with supporting backwash water pump.

Further, the described backwash water power of pumping is 100 m3/h, and lift is 0.2MP.

Owing to adopting technical scheme as above, the present invention has following beneficial effect:

Soften water treatment process of the present invention, described technique not only operation pressure stabilization, and effectively can improve the water quality of softening water, simultaneously, described technique can also effectively avoid resin contaminated when carrying out sofening treatment, thus enabling reach more than 5 years the work-ing life of resin, this is greatly for user saves production cost.

[embodiment]

Can explain the present invention in more detail by the following examples, disclose object of the present invention and be intended to protect all changes and improvements in the scope of the invention, the present invention is not limited to the following examples:

When implementing soften water treatment process of the present invention, only just need can complete efficient sofening treatment to well water by following flow operations, that is: well water--tank--boosting pump--water supply network--raw water box--raw water pump--more medium filter--activated charcoal filter--y-type filter--full-automatic softening agent--softening water tank--hot water boiler, namely the well water in tank enters raw water box by water supply network under the effect of boosting pump, well water in raw water box is inputted more medium filter by recycling raw water pump successively, activated charcoal filter and y-type filter filter accordingly, and then by full-automatic softening agent, the well water after filtration is softened, finally the well water after softening is stored in softening water tank so that hot water boiler uses,

Raw water box in described technique is the change in order to regulate flooding velocity, ensures that flooding quantity is stablized, and prevents from impacting into water fluctuation technical process simultaneously; In actually operating, according to the backwash water of former water as strainer, just enough water consumptions can be provided for the back flushing of strainer; Raw water pump is used for providing stable pressure and the water yield for follow-up water treatment, as required, 2 can be adopted to exert oneself as 30m3/h, lift are the raw water pump of 28 ~ 34m, and its operation scheme is 1 standby with 1, or provides the water source of above-mentioned flow and lift;

More medium filter is pretreatment unit important in described technique, its effect is the impurity such as fine particle, suspended substance and the colloid of the former water-band of filtering, simultaneously, for adapting to the possibility that water quality in the future degenerates, described technique can allow more medium filter run with the flow velocity of <10m/h when operating; Because more medium filter has special in low turbidity water water quality, under its separate unit strainer, water reaches more than 72 hours, and therefore, it not only has and unique is uniformly distributed water mode, but also filtration can be made to reach maximum efficiency; In addition, according to sodium bed influent quality, the requirement of producing the water water yield, arrange the vertical more medium filter that 1 diameter is 2000mm in described technical process, its separate unit is exerted oneself 30m3/h, runs flow velocity 9.55m/h; When more medium filter is when inlet outlet pressure differential reaches certain value or delivery turbidity exceeds standard, then exit use, carry out back flushing, its back flushing flow velocity is 34 ~ 49m/h; Because the back flushing flow velocity of more medium filter is generally 34 ~ 49m/h, although its water yield is larger, but required lift is lower, therefore, described technique uses independent one, and to exert oneself be 100 m3/h, lift is the backwash water pump of 0.2MP, for providing the sufficient water yield for the back flushing of more medium filter;

After activated charcoal filter is placed in more medium filter, also be important pretreatment unit, it not only can meet the requirement of turbidity for a long time, but also can organism in the former water of filtering, chlorine residue, colourity, peculiar smell, the impurity such as dust and ferrimanganic, thus ensure that effluent quality can reach sodium bed inflow requirement; Difference, for adapting to the possibility that water quality in the future degenerates, described technique can allow activated charcoal filter run with the flow velocity of <10m/h when operating; In addition, activated charcoal filter, while the above-mentioned impurity of removal, can also remove the chlorine in water, grease, colloidal silicon and remove suspended matter further, thus it is contaminated effectively to avoid resin, and then extend the work-ing life of resin accordingly; Confirm through many experiments, when water source index is turbidity≤10NTU, in described technique, the effluent index of more medium filter is turbidity≤5NTU, and the effluent index of activated charcoal filter is turbidity≤2NTU.

Part not in the detailed description of the invention is prior art, therefore the present invention is not described in detail.
