Multiplying power should be 3 or so；(2) lime treatment is used, concentration rate should be 4 or so；(3) it is dense using processing modes such as weak acid resins
Demagnification rate should be more than 4 instruction provision.These indicate provision, have absolutely proved large thermal power plant circulating water cooling treatment skill
Art, towards water saving, energy-conservation, meets several respects of environmental protection requirement to develop.But, the concentration of current most domestic power plant
Multiplying power is in less than 5 level, and this is far from being enough for the thermal power plant in serious water shortage and highrank fuel salinity water matter area.
The content of the invention
Technical problem to be solved in the utility model is to provide heat-engine plant circulating water softening, parallel seismic method device, especially
Be it is a kind of suitable for serious water shortage and haline water matter area thermal power plant.
The utility model solves the technical scheme that is used of above-mentioned technical problem：Using the compound of softening-by-pass flow desalination
Treatment, its concentration rate can reach 8.Specifically, a kind of heat-engine plant circulating water softening, parallel seismic method device, include successively
Sofening treatment equipment and side-stream treatment device, wherein, sofening treatment equipment softens dress comprising enhanced flocculation device and two-stage successively
Put；Side-stream treatment device includes reverse osmosis unit and drop alkali device, and reverse osmosis unit has concentrated water end and fresh water end, its concentrated water end
It is connected with drop alkali device, fresh water is terminated into recirculating cooling water system；Drop alkali device includes that ion-exchanger and filter drop successively
Alkali device includes ion-exchanger and filter successively, and sofening treatment equipment one end is connected with blowdown pond, the other end and by-pass flow
Processing equipment is connected；The other end of side-stream treatment device is connected with the water supplement port of circulating water water system.
Preferably, equipped with two clarifiers of a diameter of 42m, gross capability is 5000m to sofening treatment equipment3/h。
Preferably, circulating-water bypass device for processing streams presses the 3% of quantity of circulating water as parallel seismic method amount.
Further, every 6, the machine (660MW) of filter in drop alkali device, the every 267m that exerts oneself3/h；In drop alkali device
Ion-exchanger tank, per 4, machine, it is 1552m that it is exerted oneself3/ h, can deliming, magnesium ion.
Preferably, reverse osmosis unit sets two groups, every group of disposal ability 187.5m per machine3/h。
It should be noted that the reverse osmosis unit in side-stream treatment device can be exchanged with the position of drop alkali device, also
It is to say, drop alkali device is connected with two-stage softening plant；Reverse osmosis unit one end with drop alkali device be connected, the other end directly with circulation
Water-cooled water but water system water supplement port connection.In this case, for the extra high recirculated water of salinity, the mistake in drop alkali device
Filter can be connected with two-stage softening plant by another pipeline, so as to realize softening twice and the drop alkali of recirculated water.Compare
Prior art, by the recirculated water of present invention treatment, its concentration rate can reach 8, greatly save and use water, and improve
The qualification rate of cycle water.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is schematic diagram of the present utility model.
Specific embodiment
