Embodiment 2
Present embodiments provide a kind of absorption tower (desulfurizing tower) liquid level measurement method, wherein the absorbing tower liquid-level
Height measurement method is realized using the absorbing tower liquid-level height measuring device applied to overflow pipe position that embodiment 1 provides
Comprising step in detail below:
The design instruction quantization parameter for searching the desulfurizing tower determines that liquid level of slurry design is high inside Desulphurization for Coal-fired Power Plant tower
For degree between 8m-9m, it is 9m that highest, which designs liquid level, and minimum design liquid level is 8m.Therefore in the device that embodiment 1 provides, limit
The height of bit switch is 9m, and the scale range of graduated scale is 7m-9m；Wherein scale lower limit stays the surplus of 1m.
After measuring device puts into operation, float is suspended in slurry surface when unit operates normally, and foam can pass through float overflow,
Influence is put aside.After float is stablized in overflow pipe, by aobvious position disk can outside tower qualitative analysis liquid level of slurry, and pass through aobvious position
Graduated scale near disk quantitatively determines liquid level numerical value in tower.
In the present embodiment, after stable operation of unit, liquid level numerical value in tower is quantitatively determined by showing the graduated scale near the disk of position
For 8.5m.
Comparative example 1
The device and traditional desulfurization slurry liquid level emasuring device provided simultaneously equipped with embodiment 1 on desulfurizing tower, system is just
Often compare the test result of the two when operation.
By embodiment 2 it is found that liquid level numerical value is 8.5m in the tower for using device and method provided by the invention to determine.
Also, since vapour phase medium will appear violent increased situation (i.e. foaming phenomena) in slurries in desulfurizing tower, liquid level of slurry can be with
The power of blistering degree and there is level fluctuation (in tower liquid level numerical value mobility scale be 8.4m-8.6m), and use the present invention
