The physics water quality such as suspension and turbidity etc. of energy shower water are seriously overweight, are easily caused fouling of heat exchangers（Soft dirt）, at this moment
If blowdown can only be selected without physical filtering, a large amount of expensive new water are wasted, the waste of water resource is caused.Meanwhile, because right
Water quality situation can not detect in real time, and blowdown flow rate is incorrect, blowdown can all cause water resource waste or pipeline scale, shadow not in time etc.
Ring service life.The problem influences the application of evaporative type cooler always.
Utility model content
The technical problem that the utility model is solved is providing a kind of thermal power plant's dry and wet association system shower water processing system
Filter processing system by system, the shower water of particularly a kind of achievable backwash blowdown.
The technological means that the utility model is used is as follows.
Parallel connection is provided with by a kind of thermal power plant's dry and wet association system shower water on filter processing system, the outlet pipeline in pond
At least two filter of parallel connection is set on the pipeline after at least one centrifugal pump, centrifugal pump, pond is back to after converging, in mistake
The parallel connection of filter device converges outlet and sets outlet electric valve, the path of a filtering formed above；At least two filter
Water inlet before, the backwash pipeline for being respectively arranged with triple valve and being connected with triple valve.
Further, above-mentioned other filter processing system includes 2 centrifugal pumps, and the pipeline of 2 centrifugal pumps is set simultaneously after converging
The backwash that triple valve and each triple valve are connected respectively is set respectively before 2 filters of connection, 2 filter water inlets
Pipeline.
Above-mentioned backwash pipeline is all connected with blowoff line, and the blowoff line can be the blowoff line in pond, the row of being provided with
Dirty flowmeter, blowdown variable frequency pump.
Butterfly valve and switch are set before or after centrifugal pump described above, and the centrifugal pump, butterfly valve and switch are all connected with automatically controlled
Cabinet.
The top in pond sets floating ball valve of rehydration and the water pipe used cooperatively with it, set thereon moisturizing stop valve and
Refill flow meter, basin side wall is additionally provided with pond liquid level meter.
Having the beneficial effect that produced by the utility model.
1）Because power plant's air ambient is poor, the water-spray system that easily pollution is opened wide, this programme is set by shower water at filter
Reason system, husky filter is carried out to shower water, removes suspended impurity, reduction turbidity, is recoiled by pressure difference control in side filter processing system
Time and number of times are washed, the limitation of physics water quality is released, spray water circulation concentration rate is improved, timely water quality is carried out with reaching
Regulation updates, and shower water is remained more good water quality, while reducing blowdown number of times and water amount of blowdown, and reaches anti-
Only fouling is to avoid exchange capability of heat from declining.
2）Variable frequency pump blowdown is forced to shower water selection, and carries out flow measurement, can according to spray water quality test with it is dense
The control of demagnification rate carries out blowdown flow rate and the control of blowdown mode, reaches the control and water saving of water quality.
3）Physical cleaning is carried out to shower water by blowdown and both approach of filtering, pipeline scale is prevented, effectively extension
Service life, while greatling save water resource, reduces use cost.
Brief description of the drawings
Fig. 1 is the flow chart of the utility model embodiment.
Embodiment
The utility model protects a kind of thermal power plant's dry and wet association system spray water treatment system, particularly a kind of achievable anti-
Wash filter processing system by the shower water of blowdown.
Above-mentioned spray water treatment system includes at least 1 centrifugal pump, at least two filter and corresponding at least two three
The composition such as port valve, 1 outlet electric valve 12, some pressure switches, electrical control cabinet and pipeline, some valves.
Most preferred embodiment of the present utility model is illustrated, using 2 × 350MW fired power generating units construction drawing design to rely on, using 2
Centrifugal pump delivers the water 2 filters and carries out returning to pond after sand filtration, realizes and removes suspended impurity, reduces the effect of turbidity
Really.
2 centrifugal pumps 7 of parallel connection are provided with the outlet pipeline 14 in pond, setting butterfly valve and switch before and after it, using electricity
Control cabinet controls its start.The filter 8 and 9 of parallel connection is provided with after centrifugation pump conduit in parallel converges, after the parallel connection converges
It is back to pond, the path of a filtering formed above.Converge outlet in the parallel connection of filter and outlet electric valve 12 is set, use
In the above-mentioned filtering path of closing.
It is of the present utility model to focus on, before the water inlet of 2 filters 8 and 9, it is respectively arranged with triple valve 10
With 11, and the backwash pipeline 101 and 111 being connected respectively with the triple valve 10 and 11, the backwash pipeline 101 and 111 it is another
End is connected to blowoff line 13.As illustrated, blowoff line 13 can be the blowoff line in the pond, blowdown flow is provided with
