Technical field
The present invention relates to a kind of absorbing tower liquid-level height measuring devices and method for considering slurries foam falseness liquid level, belong to
Flue gas desulfurization technique field.
Background technique
Trend is transformed to comply with national coal unit minimum discharge requirement and coal electricity peak regulation flexibility, power plant is to thermal motor
Group desulfurizer performance requirement is higher and higher.Generally, absorption tower is counter current contacting, that is, sulfur-bearing flue gas from tower bottom into
Enter, absorbent enters from tower top, completes the process of flue gas desulfurization.If the liquid level of absorb the bottom of the tower is excessively high, flooded flue gas into
Enter the entrance of desulfurizing tower, flue gas is not just into next.If absorbing tower liquid-level is too low, it be easy to cause circulation pump depletion, circulating pump one
Denier evacuates, and the liquid of tower bottom does not recycle, and liquid level rapidly rises, and can also flood the entrance of flue gas.So desulfurization slurry liquid level
Precise measurement to instruct desulfurizing tower operation have extremely important meaning.
Currently, traditional thionizer liquid level measurement uses the form of pressure transmitter.In actual motion, in Desulfurization tower slurry
Vapour phase medium will appear violent increased situation (i.e. foaming phenomena), but pressure transmitter measurement position is under blistering position,
Its measured value P is unchanged, and operations staff cannot adjust operating condition according to level fluctuation in time, so as to cause control error.
For this reason, it is necessary to which existing thionizer liquid level measuring device is improved and optimized, reduce measurement error, preferably
