Abstract
The utility model discloses a kind of for 1000MW set generator internal cooling water device, comprise the water circulation system connected and composed successively by interior generating set, cold water storage cistern, water pump, resin container, resin catcher, described resin container adopts hydrogen-oxygen type resin container, sodium form resin container, the parallel connection of h type resin tank in systems in which, and described hydrogen-oxygen type resin container, sodium form resin container are separately provided with pipeline with the bottom of h type resin tank and are communicated with resin regeneration tank.The utility model can control to use different resin container according to processing requirement respectively, can control inner cold water water-quality guideline continuously and stably, ensure inner cold water pH value 8.0 ~ 9.0, specific conductivity at 0.4 ~ 2.0 μ s/cm, content of copper ion is in acceptability limit; Owing to being configured with regenerating unit, resin can Reusability, saves running cost.
Description
Technical field
The utility model belongs to generating set cooling-water treatment apparatus, is specifically related to a kind of for 1000MW set generator internal cooling water device.
Background technology
The inner cold water water quality of generator is defective will cause generator hollow core copper conductor corrosion and scaling and blocking, even cause generator to burn time serious.Once just there is generator burnout failure in yueyang, hunan power plant, therefore the inner cold water purifying treatment of generator is very important, and internal cooling water mode conventional at present has following two kinds: one is little mixed bed method, and another kind is micro-alkalinisation treatment method.These two kinds of methods are all adapt to inner cold water old plant DL/T801-2002 and widely used technology.
The standard DL/T801-2010 newly promulgated for 2010 requires that the scope of pH is at 8.0-9.0, and little mixed bed method originally and micro-alkalization method are difficult to the requirement reaching new standard, so there is a lot of implementation in power plant technological transformation, make it the requirement meeting new standard.
A lot of repowering is had to adopt the method for two resin container to solve pH problem on the low side at present, but in the application process of reality, find that water outlet pH starts more than 8.0, will less than 8.0 be dropped to after about one month, cannot adjust because resin ratio is fixing, change resin frequently and cause very large waste, bring hidden danger also to the safety of generating set.
Utility model content
The purpose of this utility model can not meet new standard requirement for prior art, provides a kind of simple to operate, safe and reliable, treatment effect good for 1000MW set generator internal cooling water device.
For the technical scheme realizing the employing of the utility model object is as follows:
What the utility model provided determines cold water treatment device for 1000MW generating set, comprise the water circulation system connected and composed successively by generating set, inner cold water case, water pump, resin container, resin catcher, described resin container adopts hydrogen-oxygen type resin container, sodium form resin container, the parallel connection of h type resin tank in systems in which, and described hydrogen-oxygen type resin container, sodium form resin container are separately provided with pipeline with the bottom of h type resin tank and are communicated with resin regeneration tank.
The beneficial effects of the utility model:
1, can control respectively to use different resin container according to processing requirement, inner cold water water-quality guideline can be controlled continuously and stably, ensure inner cold water pH value 8.0 ~ 9.0, specific conductivity at 0.4 ~ 2.0 μ s/cm, content of copper ion is in acceptability limit.
2, use simple to operate, unmanned.
3, resin loads respectively, is configured with regenerating unit simultaneously, and resin can Reusability, saves running cost.
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, what the utility model provided determines cold water treatment device for 1000MW generating set, comprise the water circulation system connected and composed successively by generating set 1, inner cold water case 15, water pump 14, three resin containers, resin catchers 2, in systems in which, they are respectively hydrogen-oxygen type resin container 10, sodium form resin container 11, h type resin tank 12 in three resin container parallel connections; The water inlet pipe of hydrogen-oxygen type resin container 10, sodium form resin container 11 and h type resin tank 12 is provided with total water intaking valve 13, and their bottom is respectively equipped with outlet valve 9,7,5, and their bottom is separately provided with pipeline respectively and is communicated with resin regeneration tank 3 with valve 8,6,4.
When the utility model runs, in hydrogen-oxygen type resin container 10, load hydrogen-oxygen type resin, load in sodium form resin container 11 in sodium form resin, h type resin tank 12 and load h type resin, under the effect of water pump 14, water in inner cold water case 15 is after three resin container process, by resin catcher 2, get back to the stator coil of generating set 1, after the heat absorption that generator is produced, is returned inner cold water case 15.When system is run first, by adjusting the flow of water valve 5,7,9, the pH value of the inner cold water recycle system, specific conductivity and content of copper ion can be controlled in qualified scope; Long-play is along with the carrying out of ion-exchange, and the situation that pH declines appears in the water in system, at this moment the outlet valve 7 of sodium form resin container 11 can be tuned up, and turns down corresponding for the outlet valve 5 of h type resin tank 12, just can continue to run; In any case namely regulate when resin complete failure time can not be all realize pH in acceptability limit time, respectively the resin of three resin containers is imported to resin regeneration tank 3 by valve 4,6,8 and carry out recovery regeneration, then again import resin container, adjust penstock and namely can realize qualified effluent quality.
