Description
Technical field
The present invention relates to a kind of limestone-based process spray column slurry density measurement device, belongs to field of environment protection.
Background technology
Wet process of FGD spray column is a kind of spray equipment that sprayed slurry is recycled, and loop slurry adopted mostly
Lime stone slurry, by the Ca in serosity2+With the SO in flue gas2Reaction generates CaSO4, by the SO in flue gas2Remove so as to reach
The purpose of purifying smoke.When the continuous circulated sprinkling of lime stone slurry until circulation fluid in CaSO4Reach certain proportion, and circulation fluid
PH value reduce desulfuration efficiency decline after, will circulation fluid discharge a part, continue cycling through after being supplemented with fresh lime stone slurry
Spray.So when a part of serosity of the outer row is supplemented with new serosity, is a very important ginseng in desulfurizing tower running
Number.The parameter is controlled, the stable of desulfuration efficiency has not only been can guarantee that but also lime stone slurry can be saved, reduced operating cost, it is more important
Be to control CaSO4Concentration can prevent in crystallization inside tower, so as to block shower nozzle and other tower internals, cause desulfurizing tower to stop transport
Phenomenon generation.
The desulfurizing tower of early stage is the mode that online PH meter is set up in bottom of towe slurry layer, by the monitoring of online pH value so as to sentencing
It is disconnected when to discharge serosity.But as loop slurry is the buffer solution of strong acid weak base, the pH value of monitoring can not reaction slurry well
Actual numerical value in liquid, along with CaSO4Can count in PH and crystallize on probe so as to many reasons such as cause PH measurements amount inaccurate
Occur, cause in actual motion can not control plasma discharge time well, reduce desulfuration efficiency, crystallization inside tower can more seriously occur
Phenomenon.
By improvement, using measurement CaSO4The mode of density can prevent above-mentioned phenomenon from occurring, by measuring CaSO in tower4's
Density can directly know CaSO4Volumetric concentration so as to being accurately controlled the plasma discharge time.Earliest by the way of density skill, but adopt
Similarly there is instrument check with the direct method of measurement to be forbidden, pop one's head in CaSO4The generation of the phenomenon of crystallization is forbidden so as to cause measurement.
Later, by way of installing pressure transducer additional in serosity area diverse location, directly measured by two pressure transducers tested
The pressure differential in amount area, then according to density formula：ρ=P/gh (P：Interval pressure differential h of serosity area differing heights：Two pressure measurement
Vertical dimension between point) calculate indirectly CaSO4Density, pressure transducer do not affected by crystallizing, measurement accurately so as to
Solve the problems referred to above.The mounting means of pressure transducer is shown in accompanying drawing 1.
By the operation of a period of time, the shortcoming of this kind of mounting means also gradually manifests, is mainly shown as：
1st, the serosity in pipe nipple 1 and pipe nipple 2 is " dead band ", it is impossible to flowed well, and the serosity in serosity area has density
Difference.
2nd, need frequently backwash to be carried out using tap water, increase the ratio of water in serosity, be unfavorable for desulfuration efficiency
Lifting.
3rd, the easy fouling of " dead band " serosity in pipe nipple, blocks measurement pipe, causes measurement inaccurate.
The content of the invention
The present invention is to solve the problems, such as to cause measurement inaccurate due to " dead band " and fouling, there is provided a kind of limestone-based process spray
