Abstract

Promote desulfurization densimeter reliability device. The density of the slurry is calculated only by the upper and lower differential pressure, and if the zero position of the transmitter is not accurate, the method can generate calculation deviation, thereby influencing the measurement accuracy. The utility model discloses the constitution includes: desulfurization prewashing tower (1) and differential pressure transmitter (2), desulfurization prewashing tower and box (7) through drain pipe (3) intercommunication, the box other end blow off pipe (8) have, the box inside be fixed with dead lever (6), kickboard (5) with dead lever sliding fit, the kickboard on be fixed with the densimeter. The utility model is used for promote desulfurization densimeter reliability.

Description

Device for improving reliability of desulfurization densimeter

The technical field is as follows:

the utility model relates to a promote desulfurization densimeter reliability device.

Background art:

the existing thermal power plant desulfurization absorption tower adopts a differential pressure type measurement principle to measure the density of slurry, if a differential pressure transmitter fails, the method needs to be replaced, but one-time door corrosion is not tight in sealing, slurry can be sprayed out during the treatment of maintainers, the height of the slurry is 10 m, the differential pressure transmitter is arranged at the bottom, the pressure is huge, and the safety of crisis personnel and equipment can be caused.

The density of the slurry is calculated only by the upper and lower differential pressure, and if the zero position of the transmitter is not accurate, the method can generate calculation deviation, thereby influencing the measurement accuracy.

Install the differential pressure transmitter in the thick liquid bottom, receive pressure influence for a long time, the pressure diaphragm capsule not only produces the deformation, can damage the densimeter moreover, has improved manufacturing cost, also makes maintainer consume energy. In the process of maintenance, a maintainer can work only when the unit stops running, so that the work is inconvenient greatly.

The utility model has the following contents:

the utility model aims at providing a promote desulfurization densimeter reliability device.

The above purpose is realized by the following technical scheme:

the utility model provides a promote desulfurization densimeter reliability device, its constitution includes: desulfurization prewashing tower and differential pressure changer, desulfurization prewashing tower and box pass through the drain pipe intercommunication, the box other end blow off pipe has, the box inside be fixed with the dead lever, the kickboard with dead lever sliding fit, the kickboard on be fixed with the densimeter.

The device for improving the reliability of the desulfurization densimeter is a tuning fork densimeter.

Has the advantages that:

1. the utility model discloses in introducing next door iron box with desulfurization prewashing tower thick liquid, at the top installation tuning fork densimeter, submerge the densimeter probe, the thick liquid in the box passes through the blow off pipe and discharges for form the stable liquid level of flow in the box, through tuning fork densimeter measurement density, improve density measurement's accuracy, do not need the unit to stop the transport when pressure differential transmitter breaks down, can real-time measurement thick liquid density.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention;

in the figure: 1. a desulfurization prewashing tower; 2. a differential pressure transmitter; 3. a liquid outlet pipe; 4. a tuning fork densitometer; 5. a floating plate; 6. fixing the rod; 7. a box body; 8. a sewage discharge pipe.

The specific implementation mode is as follows:

as shown in fig. 1, this device includes desulfurization prewashing tower 1 and pressure differential transmitter 2, the pressure differential transmitter is installed in desulfurization prewashing tower bottom, draw forth a drain pipe 3 with desulfurization prewashing tower downside and communicate to a box other end of box 7 has blow off pipe 8, the box is the iron box, be fixed with the dead lever respectively in the inside both sides of box, two round holes have been seted up on the kickboard, kickboard 5 and 6 sliding fit of dead lever, make the slurry flow in the box after the kickboard can float, fix tuning fork densimeter 4 on the kickboard through the bolt, can guarantee like this that the probe of tuning fork densimeter lower extreme is always below the liquid level, guarantee the accuracy to the density measurement, install the valve on drain pipe and the blow off pipe respectively, the pipe diameter of drain pipe and blow off pipe is unanimous, open the valve of drain pipe, the valve of drain pipe is closed, make the slurry in the desulfurization prewashing tower flow out to the box through the drain pipe, make the liquid level of box rise gradually, open the valve of drain pipe when rising to the kickboard floats, because the pipe diameter of drain pipe is unanimous with the pipe diameter of drain pipe, make it keep stable in the box, make it carry out the density measurement.

Claims (2)

1. The utility model provides a promote desulfurization densimeter reliability device, its constitution includes: desulfurization prewashing tower and pressure differential changer, characterized by: the desulfurization prewashing tower and the box body are communicated through a liquid outlet pipe, the other end of the box body is provided with a sewage discharge pipe, a fixed rod is fixed inside the box body, a floating plate is in sliding fit with the fixed rod, and a densimeter is fixed on the floating plate.

2. The device for improving the reliability of a desulfurization densitometer of claim 1, wherein: the densimeter is a tuning fork densimeter.
