Abstract
The utility model discloses a close measuring device in absorption tower, including absorption tower, densimeter, pit and scum pipe, there is a thick liquid pipeline absorption tower bottom side and middle part side all switch -on, and the one end that the pipeline exit end inserted densimeter bottom and scum pipe is simultaneously starched to the scene 2, a densimeter top cartridge U -shaped pipe, the U -shaped pipe other end inserts in the pit. Change the connection of traditional densimeter, flow next thick liquid from up passing through the densimeter down with the absorption tower for the thick liquid is full of the space of densimeter the inside, the more accurate density of measuring slurry in absorbtive tower, and simultaneously also can be better monitor the absorption tower has avoided that the cost is extravagant has also guaranteed the control to waste gas.
Description
Technical field
This utility model is related to thermal power plant systematic parameter fields of measurement, and in particular to a kind of absorption tower density measure dress
Put.
Background technology
At present.The desulfuration absorbing tower density measuring equipment in thermal power plant, is directly to discharge pump discharge main pipe from calcium plaster
Draw downwards and connect a pipeline, densimeter measurement device is connect on pipeline, the serosity after densimeter measurement flows into absorption tower ground
Hole, then serosity is squeezed in absorption tower by sump pump.The problem for existing so is installed：One is if densimeter entrance door is opened greatly
, densimeter can be measured accurately, but, sump pump undercapacity big through the slurry flow of densimeter outflow, melt pit is easily completely
Slurry causes environmental pollution, and affects the feeding coal of calcium plaster excavationg pump to dewaterer；Two is that densimeter entrance door opens little, Jing
Cross densitometric slurry flow little, serosity can not be full of densimeter, and densimeter is without pressure, and density measure is inaccurate.Due to upper
Reason is stated, existing thermal power plant desulfuration absorbing tower densimeter on-line monitoring is inaccurate always, and desulfurization operation adjustment is difficult, leads
Consistency meter performs practically no function, and it is improper that the monitoring on absorption tower is also held, and easily causes that quick lime is wasted and sulfur dioxide is to environment
Pollution.
Utility model content
This utility model aims to provide a kind of absorption tower density measuring equipment, to solve existing absorption tower density measure dress
Put inaccurate the brought above-mentioned problems of measurement.
This utility model is achieved by following technical solution：
A kind of absorption tower density measuring equipment, including absorption tower, densimeter, melt pit and scum pipe, the absorption tower bottom
Side and middle part side have been turned on pulp pipeline, and two pulp pipe outlets access the one of densimeter bottom and scum pipe simultaneously
End, the densimeter top inserts a U-tube, and the U-tube other end is accessed in melt pit.
The pipeline for accessing densimeter bottom is provided with densimeter inlet valve.
Sump pump is provided with the melt pit.
The pulp pipeline is provided with slurry discharge pump.
Slurry discharge pump two ends on the pulp pipeline are equipped with electric butterfly valve.
The U-tube is reverse mounted.
The beneficial effects of the utility model are：
Compared with prior art, a kind of absorption tower density measuring equipment that this utility model is provided, changes conventional densities meter
Connection, the serosity that absorption tower is flowed out is from the bottom up through densimeter so that serosity full of the space inside densimeter, more
The density of absorption tower serosity is accurately measured, while also preferably can be monitored to absorption tower, it is to avoid cost is wasted
Ensure that the control to waste gas.
Description of the drawings
Fig. 1 is structure diagram of the present utility model；
In figure：1- absorption towers, 2- densimeters, 3-U shape pipes, 4- melt pits, 5- scum pipes, 6- sump pumps, 8- electric butterfly valves, 9-
Slurry discharge pump, 10- densimeter inlet valves, 11- pulp pipelines.
Specific embodiment
The technical solution of the utility model is described further below in conjunction with accompanying drawing, but required protection domain is not
It is confined to described；
As shown in figure 1, this utility model provide a kind of absorption tower density measuring equipment, including absorption tower 1, densimeter 2,
Melt pit 4 and scum pipe 5, the bottom sides of the absorption tower 1 and middle part side have been turned on pulp pipeline 11, and two pulp pipelines 11 go out
One end of the bottom of densimeter 2 and scum pipe 5 is accessed at mouth end simultaneously, and the top of the densimeter 2 inserts a U-tube 3, and U-tube 3 is another
Terminate in melt pit 4, the serosity that absorption tower 1 flows out flows through from the bottom up densimeter 2 Jing after pulp pipeline 11 so that serosity fills
The space of the full the inside of densimeter 2, more accurately measures the density of the inside serosity of absorption tower 1, so just can preferably to absorbing
Tower is monitored, it is to avoid cost is wasted and also ensure that the control to waste gas.
The pipeline for accessing the bottom of densimeter 2 is provided with densimeter inlet valve 10, after the inside serosity of melt pit 4 has been expired,
Densimeter inlet valve 10 is closed, can effectively be avoided melt pit 4 from overflowing and be caused environmental pollution.
Sump pump 6 is provided with the melt pit 4, for the serosity of the inside of melt pit 4 to be transported back in absorption tower 1.
The pulp pipeline 11 is provided with slurry discharge pump 9, and more timely absorption tower can be monitored.
The two ends of slurry discharge pump 9 on the pulp pipeline 11 are equipped with electric butterfly valve 8, facilitate densimeter 2, scum pipe 5,
A series of replacing of follow-up equipments such as melt pit 4, maintenance, cleaning.
The U-tube 3 is reverse mounted, i.e., be first to rise to decline afterwards when serosity flows through U-tube 3, is easy to densimeter 2
Install, also cause serosity to fill up densimeter 2 from the bottom up.
