Abstract
The utility model discloses a combined measurement device for a liquid level and density of a desulfurization absorption tower. The combined measurement device comprises a liquid level signal collecting device and a data processor (1). The liquid level signal collecting device is composed of at least three static pressure liquid level transmitters (2) arranged on the desulfurization absorption tower (3) by specifying the height, and the static pressure liquid level transmitters (2) are connected with the data processor (1) respectively through signal lines. The combined measurement device has the advantages that the static pressure liquid level transmitters with specified height are arranged on the desulfurization absorption tower, subsection redundant liquid level value and density value are obtained through conversion, reliability is good, precision is high, the reliability is guaranteed, cost of device is reduced, and simultaneously, maintenance of a system is reduced, and calibration revision is convenient.
Description
Technical field
The utility model relates to desulfuration absorbing tower liquid level and density combinations measurement mechanism.
Background technology
The absorption tower is parts main in the sulfur removal technology, and the density of the liquid level of reaction liquid and reaction liquid all affects desulfurized effect in the absorption tower, is crucial factor.Serum density mainly adopts two kinds of densitometers to measure in the existing tower, and one is the pipeline densitometer, and this densitometer precision is higher, but system reliability difference and costing an arm and a leg; Two is the differential density meter, and this densitometer price comparison is suitable, but system reliability is poor, and precision is low, is difficult to continuous operation.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of good reliability, desulfuration absorbing tower liquid level and density combinations measurement mechanism that precision is high are provided.
The purpose of the utility model realizes through following technical scheme: desulfuration absorbing tower liquid level and density combinations measurement mechanism; It comprises liquid level signal gathering-device and data processor; Affiliated liquid level signal gathering-device is made up of at least three static pressure fluid level transmitters that are installed on the desulfuration absorbing tower through specified altitude assignment, and the static pressure fluid level transmitter is connected with data processor respectively through holding wire.
This device is through the DSC programming.
Liquid level in the described desulfuration absorbing tower is 7～12m.
The beneficial effect of the utility model is: through the static pressure fluid level transmitter specified altitude assignment is installed in the mode on the desulfuration absorbing tower; Obtain redundant level value of segmentation and density value through conversion, good reliability, precision are high, have not only guaranteed reliability but also have reduced the cost of equipment; Simultaneously; Device type is few, has reduced the maintenance of system, revises and demarcates conveniently.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure, 1-data processor, 2-static pressure fluid level transmitter, 3-desulfuration absorbing tower.
The specific embodiment
Further describe the technical scheme of the utility model below in conjunction with accompanying drawing, but require the scope of protection to be not limited to said.
Like Fig. 1; Desulfuration absorbing tower liquid level and density combinations measurement mechanism; It comprises liquid level signal gathering-device and data processor 1; Affiliated liquid level signal gathering-device is made up of at least three static pressure fluid level transmitters 2 that are installed on the desulfuration absorbing tower 3 through specified altitude assignment, and static pressure fluid level transmitter 2 is connected with data processor 1 respectively through holding wire.
This device is used to carry out mathematical conversion through the DSC programming.
Liquid level in the described desulfuration absorbing tower 3 is 7～12m.
With three static pressure fluid level transmitters is example; Static pressure fluid level transmitter 2 through three specified altitude assignments being provided with; Static pressure fluid level transmitter 2 has been accomplished the triple redundance liquid level in desulfuration absorbing tower 3 conventional operation liquid level scopes; And through the difference in height and the static pressure fluid level transmitter registration of static pressure fluid level transmitter 2, the difference in height of three static pressure fluid level transmitters is designated as L respectively
1, L
2, L
3, static pressure fluid level transmitter registration is respectively L
