Background technology
Along with the raising of fuel-burning power plant parameter, capacity, and the application of one through boiler, boiler feedwater quality is proposed to more and more higher requirement.The boiler feedwater of the thermal power generation unit of current domestic high-parameters is all de-mineralized waters, and the technical process that Boiler water Feeding System system mainly adopts is: by filter plant, pass through successively cation exchanger, anion exchanger to mixed ion exchanger.This system is before putting into operation, in backwash and regenerative process, can produce a large amount of drainings, at present domestic Electric Design unit is when carrying out heat power plant boiler supplementary feed Processing System Design, all do not consider the cascade utilization problem of water saving or the draining of this system, cause this system before putting into operation, in backwash and regenerative process, have and a large amount of compared with pure water and waste water, be jointly discharged in wastewater disposal basin, then by waste water pump, waste water being delivered to Waste Water Treatment processes, not only cause the waste of great lot of water resources, also medicine consumption and the energy consumption of Waste Water Treatment because of the increase of wastewater treatment, have been increased, increase working cost.
Utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of water-saving Boiler water Feeding System system is provided, by a part of draining in Boiler water Feeding System system is recycled, reduces fresh water withdrawal, reduce discharge of wastewater, reach the object of saving water and energy.
The utility model is that technical solution problem adopts following technical scheme:
The water-saving Boiler water Feeding System system of the utility model, comprises strainer, cation exchanger, anion exchanger and mixed ion exchanger; Its constructional feature is: a recovery pond is set, the draining of just washing of described strainer, cation exchanger, anion exchanger and mixed ion exchanger is reclaimed pond by the female pipe access of draining, and the backwash draining of described cation exchanger, anion exchanger and mixed ion exchanger is discharged female pipe access by backwash and reclaimed pond; The regeneration draining of described cation exchanger, anion exchanger and mixed ion exchanger accesses in described recovery pond to the female pipe of draining or by reclaiming water valve, or by discharge of wastewater valve access wastewater disposal basin; In described recovery pond, recovered water pump is set, the pump discharge of described recovered water pump is connected with make up water pipeline in circulating water system.
The constructional feature of the water-saving Boiler water Feeding System system of the utility model is also, in the female pipe of described draining, specific conductivity table is set, and controls the break-make that reclaims water valve and discharge of wastewater valve according to the detection signal of described specific conductivity table.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model, by most of draining in Boiler water Feeding System system is recycled, effectively reduces fresh water withdrawal, has reduced wastewater discharge, thereby reaches the object of saving water and energy.
2, the utility model does not change existing device structure, only increases pipeline, valve and instrument setting, and increases to arrange and reclaim pond and recovered water pump, and its investment is little, and effect is remarkable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Number in the figure: 1 strainer; 2 cation exchangers; 3 anion exchangers; 4 mixed ion exchangers; The female pipe of 5 drainings; 6 reclaim water valve; 7 discharge of wastewater valves; 8 reclaim pond; 9 recovered water pumps; 10 conductivitimeters; The female pipe of 11 backwash drainings
Embodiment
Referring to Fig. 1, in the present embodiment, water-saving Boiler water Feeding System system comprises strainer 1, cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4; One recovery pond 8 is set, the draining of just washing of strainer 1, cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 is reclaimed pond 8 by female pipe 5 accesses of draining, and the backwash draining of cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 is discharged female pipe 11 accesses by backwash and reclaimed pond 8; The regeneration draining of cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 is reclaimed in pond 8 to the female pipe 5 of draining or by reclaiming water valve 6 accesses, or by discharge of wastewater valve 7 access wastewater disposal basins; In reclaiming pond 8, recovered water pump 9 is set, the pump discharge of recovered water pump 9 is connected with make up water pipeline in circulating water system.
In concrete enforcement, in the female pipe 5 of draining, specific conductivity table 10 is set, according to the detection signal of specific conductivity table 10, controls the break-make that reclaims water valve 6 and discharge of wastewater valve 7.
In the present embodiment, the water saving of boiler feedwater accepting/ordering system is to carry out as follows:
By most of draining of reclaiming in pond 8 recovery strainers 1, cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 operating process.
Cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 backwash drainings are directly accessed and are reclaimed pond 8 by the female pipe 11 of backwash draining.
Before strainer 1, cation exchanger 2, anion exchanger 3 and mixed ion exchanger 4 put into operation, just washing draining is directly accessed and is reclaimed pond 8 by the female pipe 5 of draining.
When desalting system carries out regenerative operation, cation exchanger 2 and anion exchanger 3 can be regenerated (unit system) simultaneously or regenerate respectively (piping-main scheme), and mixed ion exchanger 4 is regenerated separately.
Cation exchanger 2, anion exchanger 3, mixed ion exchanger 4 discharge water while regenerating, the draining of pilot injection directly accesses recovery pond 8 by the female pipe 5 of draining.
Displacement during 4 regeneration of cation exchanger 2, anion exchanger 3, mixed ion exchanger, littlely just wash, just washing draining and decide discharge or reclaim according to the specific conductivity table 10 being arranged on the female pipe 5 of draining, when specific conductivity indicating value is greater than 25us/cm, draining is by the female pipe 5 of draining and discharge of wastewater valve 7 access wastewater disposal basins, when specific conductivity indicating value is less than 25us/cm, draining is reclaimed pond by the female pipe 5 of draining and 6 accesses of recovery water valve.
The recycle-water that reclaims pond 8 can be delivered directly to other user in power plant by recovered water pump 9 and use, as recirculated cooling water make up water pipeline or circulating water pool, Yuan Shui pond etc. (being obviously better than the supplementary water quality of recirculated cooling water and raw water quality because reclaim the water quality in pond).
