Description
Technical field
The present invention relates to power plant or field of chemical equipment, specifically a kind of online resin sampling device and sampling method.
Background technology
The reliability service of condensed water precision processing system is for ensureing that unit thermodynamic system water and steam quality plays an important roll, especially
It is supercritical once-through boiler, and its requirement to water and steam quality is higher.High flow rate mixed bed water treatment technology is that condensate polishing treatment is normal
Water treatment technology mode.Processing of the high flow rate mixed bed to water quality rely primarily on the ion-exchange capacity of yin, yang hybrid resin with
Filtration.After mixed bed runs a period of time, hybrid resin will fail, it is necessary to separated and regenerated, now positive resin
Regeneration level and separating degree with negative resin be influence the high flow rate mixed bed condensed water precision processing system cycle of operation and exert oneself it is important
Factor.And with the increase of mixed bed run time, the performance of resin also has different degrees of decline.Therefore, mixed in yin, yang
Resin needs to be sampled regenerating resin detection regeneration degree, separating degree and other performance index after operation certain time.
At present, standard GB/T/T 5475-2013《Ion exchange resin sampling method》In define a kind of sampler,
As shown in FIG. 1A and 1B, still, the sampler is only applicable to the wet resin in the original packaging container of resin manufacture factory, and only
It is sampled suitable for the resin to resin floor height about 500mm, and the resin bed in condensed water precision processing system bed body or tank body
It is high about 2~4 meters, therefore it has the following disadvantages：1) wet resin and sampling limited height of static state can only be taken；2) can only be can be by
Sampled in the flexible package of sampler insertion；3) it can only be sampled on different section, it is impossible to continuous sampling；4) sample taken out is easily spilt
Fall, influence the representativeness of sample.And how to be sampled for being fitted into the resin run in bed body or tank body, not related
Standard.
Prior art discloses a kind of bed body or tank body resin sampler, referring to Chinese invention patent CN103439148A, such as
Shown in Fig. 2, its be using a kind of drawing-in type structure complete resin sampling, its mainly by pressure-reducing valve 1, compressed air change-over switch 2,

Between contact.
7. online resin sampling device according to claim 1, it is characterised in that first sample cock, described
Two sample cocks and the 3rd sample cock are electrically connected with the controller respectively.
8. a kind of online resin sampling method, it is characterised in that the online resin sampling method uses such as claim 1~7
Any one of online resin sampling device, the online resin sampling method comprises the following steps：
Step a：High flow rate mixed bed conveys resin by the first delivery pipe to resin separation tower, opens the first sample cock and is taken
Sample；
Step b：The resin is separated into by negative resin and positive resin by the resin separation tower, by the second delivery pipe to the moon
Regenerator conveys the negative resin, opens the second sample cock and is sampled, while defeated by branch's probe tube regenerator that faces south
The positive resin is sent, the 3rd sample cock is opened and is sampled；
Step c：After the positive resin regenerates in the positive regenerator, pass through the 3rd sample cock on branch's probe tube
It is sampled；After the negative resin regenerates in the cloudy regenerator, pass through the 3rd sample cock on branch's probe tube
It is sampled.
9. online resin sampling method according to claim 8, it is characterised in that in the step c, pass through described point
When positive resin after regeneration is delivered to the resin separation tower by branch probe tube, opens the 3rd sample cock and be sampled,
When the negative resin after regeneration being delivered into the positive regenerator by branch's probe tube, open the 3rd sample cock and taken
Sample.
10. online resin sampling method according to claim 9, it is characterised in that also include step after the step c
D, the positive resin after negative resin and regeneration after regeneration forms regenerating resin in the positive regenerator, is sampled by the branch
The regenerating resin is delivered to the high flow rate mixed bed by pipe, is opened the 3rd sample cock and is sampled.
