Background technique
Thermal power plant's Wet Limestone Desulfurization systematic water balance is adjusted more difficult at present, in part of generating units stand-by heat, is held
Easily there are the more water of system, influence being normally carried out for all kinds of flushings, demister differential pressure is easy to increase, and absorbing tower liquid-level is difficult to control；
Simultaneously as flue gas " disappears white " development of engineering, flue gas carries water and can largely be collected back in absorption tower, the more shipwrecks of system
To avoid for the bringing normally into operation for guaranteeing flue gas " disappearing white ", it is necessary to first solve desulphurization system water balance unbalance.And it is existing de-
The measure that the more hydrominings of sulphur system take is only to control the use of flushing water plus the discharge amount for increasing waste water, and this method has stronger
Limitation, control flushing water can reduce flushing effect, influence the normal operation of device systems, the stabilization of waste water treatment system operation
Property is not high, and treating capacity is difficult to ensure.

Specific embodiment
Below by specific embodiment and in conjunction with attached drawing, the utility model is further described in detail.
As shown in Figure 1, being a kind of desulphurization system Water balance adjusting device, the device packet described in the utility model embodiment
It includes:
Composite water tank comprising the top of buffer tank 1 and clear water tanks 2,2 junction of buffer tank 1 and clear water tanks is equipped with
Overflow port 8, clear water tanks 2 are interior to be equipped with float switch 9；
Technique water tank 3 is connect with clear water tanks 2, and the pipeline between clear water tanks 2 and technique water tank 3 is recycled equipped with water purification
Pump 5.
Further, buffer tank 1 and 2 bottom of clear water tanks are equipped with exhaust-valve 10.When needing to buffer tank 1 and water purification
It, then will by the exhaust-valve 10 of the two bottom when case 2 is overhauled or needs to clear up buffer tank 1 and clear water tanks 2
Its internal water is all discharged, and realizes the maintenance or cleaning to the two.Exhaust-valve 10 herein can use existing commercially available valve
Door, as long as can be realized air emptying function herein.
Further, further include collecting water tank 13, connect with buffer tank 1, between buffer tank 1 and collection water tank 13
Pipeline be equipped with inlet valve 6.It is realized and is collected between water tank 13 and buffer tank 1 by the opening and closing of inlet valve 6
Connection and closing.
Further, further include trench 4, connect with water tank 13 is collected, on the pipeline between trench 4 and collection water tank 13
Equipped with bypass valve 7.The connection and closing collected between water tank 13 and trench 4 are realized by the opening and closing of bypass valve 7.
Extra collection water then passes through discharge of pipes into trench 4.Inlet valve 6 and bypass valve 7 select existing commercially available valve herein,
As long as can be used in the circulation or choked flow function of liquid.
Further, the influent side of water purification recovery pump 5 is equipped with the first valve 11, and the water outlet side of water purification recovery pump 5 is equipped with the
Two valves 12.When needing to carry out isolation processing to water purification recovery pump 5, then can be realized by the first valve 11 or the second valve 12
Isolation to water purification recovery pump 5.The first valve 11 and the second valve 12 are also all made of existing commercially available valve, the first valve 11 herein
It can be two identical valves with the second valve 12.
The clean water of desulphurization system, which is collected into, in the present embodiment collects in water tank 13, passes through 6 He of regulating water inlet valve later
Size that the aperture of bypass valve 7, that is, valve is opened controls the water for needing to collect in actual condition, if actual condition
The middle water for needing to collect is larger, and the aperture of inlet valve 6 is tuned up, while accordingly turning the aperture of bypass valve 7 down, when practical work
The water for needing to collect in condition is smaller, then the aperture of inlet valve 6 is turned while accordingly being tuned up down the aperture of bypass valve 7.Because receiving
The machine water shutoff for having slurries to pump in the water source that header tank 13 is collected and collection port are mostly to be open to arrange, therefore collected water purification is deposited
A possibility that being contaminated and being mixed into sundries, so first the collection water collected in water tank 13 is first delivered in buffer tank 1
Precipitated, then from overflow port 8 flow into clear water tanks 2 in, this makes it possible to guarantee enter clear water tanks 2 in collection water do not contain
Magazine or pollutant.When the water level of the clean water in clear water tanks 2 reaches the open position of upper part float switch 9, water purification recovery pump 5
It then automatically turns on, the crystallization water in clear water tanks 2 then passes through pipeline and is transported in technique water tank 3；When under the water level in clear water tanks 2
When being down to the off-position of float switch 9, water purification recovery pump 5 is then automatically stopped operation, with this reciprocal operation.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
