Survey density, direct current mounting means due to flow, hypotony, in slurries direct current process Midst density meter slurries can not full packages, cause
Densimeter measurement is inaccurate, it is impossible to be that the monitoring of operating personnel's density and slurries adjustment provide accurate foundation.However, serum density is made
For an important technological parameter, its change has extremely important influence to the technique productions in most of power plant.Therefore,
In power generation, the various correlation techniques measured slurry density of desulfurizing absorption column are also occurred in that.Such as Publication No.
CN101477020 Chinese patent document discloses a kind of method for measuring slurry density of desulfurizing absorption column, first along absorption tower
Tower body chooses low-pressure lateral pressure sample point and high side pressure sample point in vertical direction, then from high side pressure sample point
Draw sampling pipeline section respectively with low-pressure lateral pressure sample point, then by the high pressure side capillary tube of double flange barrier film differential pressure transmitters and
Low pressure side capillary tube is coupled with a sampling pipeline section, finally by the measured value Δ P of double flange barrier film differential pressure transmitters, according to
Formula ρ1=(Δ P+ ρ2Gh)/(gh) calculates ρ in density value, formula1For absorption tower serum density, ρ2Fill liquid-tight for capillary
Degree, g is acceleration of gravity, and h is the difference in height between high side pressure sample point and low-pressure lateral pressure sample point.Pass through the hair
It is bright, accurately serum density can be measured.However, being related to the change of many parameters in technology application, survey is added
The complexity of amount and the computing difficulty to these parameters, while also adding the probability of computing error indirectly, increase work
Burden.

Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- absorption towers, 2- plasma discharges hole, 3- baffle-boxs, 4- densitometers, 5- gypsum pumps, 6- pipelines A, 7- pipeline B, 8-
Hand-operated valve, 9- pumps A, 10- pump B, 11- pipeline C, 12- pipeline D.
Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in figure 1, a kind of device for serosity density measurement, including absorption tower 1, plasma discharge hole 2, densitometer 4 and stone
Cream pump, the absorption tower 1 is connected by pipeline with the water inlet of gypsum pump 5, and the plasma discharge hole 2 passes through pipeline B7 and gypsum pump 5
Delivery port connection, pipeline B7 also connected by densitometer 4 with the delivery port of gypsum pump 5.During actually measurement slurries,
Slurries in absorption tower 1 are released by gypsum pump 5, and because slurries are pressure is in 280kPa or so after gypsum pump 5, flow exists
200m3/ h or so, both ensure that slurries can be full of the measurement pipeline of densitometer 4, and had been unlikely to cause the measurement pipeline of densitometer 4 again
Block, so that densitometer 4 can guarantee that full packages is measured in measurement, meet the measurement standard of densitometer 4, enhance densitometer
The degree of accuracy of 4 measurements, and then serum density monitoring and the slurries quality adjustment on absorption tower 1 have been provided and tried hard to keep for operating personnel
Barrier.Moreover, this mounting means has saved equipment cost and factory's electric cost without increase measurement pump in addition.
The delivery port of the gypsum pump 5 is also connected by pipeline A6 with baffle-box 3.Baffle-box 3 and gypsum pump 5 are passed through into pipe
Road A6 is connected.In the process of running, fraction slurries can be caused to flow into baffle-box 3 by pipeline A6, so as to reduce pipeline B7's
Conveying burden, it is to avoid pipeline B7 the generation of booster event occurs because flow and pressure are excessive, and then extends making for pipeline B7
Use the life-span.
The gypsum pump 5 is made up of pump A9 and pump B10, and pump A9 and pump B10 water inlet pass through pipeline C11 and pipeline respectively
D12 is connected with absorption tower 1, and pump A9 and pump B10 delivery port are connected with pipeline B7 respectively.In actual applications, gypsum pump 5 is set
Put mainly as the slurries in extraction absorption tower 1.However, a single pump is operationally, may be because pump is damaged and leads
Cause whole induction system to collapse, influence being normally carried out for technique productions.Moreover, a single pump is operationally, it may appear that stream
The phenomenon of amount and insufficient pressure, the efficiency of influence slurries conveying.Therefore, gypsum pump 5 is designed as by two pumps of pump A9 and pump B10
Composition, passes through the mutual switching of two pumps, it is to avoid cause the interruption that slurries are conveyed because some pump is damaged.Meanwhile, pump A9
With pump B10 design, also cause in discharge pressure and underfed, can be by the way that while opening two pumps, there is provided enough
Flow and pressure, it is ensured that what the full packages of densitometer 4 was measured is normally carried out.
This segment pipe B7 between the densitometer 4 and gypsum pump 1 is provided with hand-operated valve 8, and the design of hand-operated valve 8 makes
The measurement for obtaining densitometer 4 is more flexible, when needing to carry out density measure, and the survey of serum density can be carried out by opening hand-operated valve 8
Amount, when that need not measure slurry density, closes hand-operated valve 8, so as to reduce erosion and impact of the slurries to densitometer 4, prolongs
The service life of densitometer 4 is grown.
