Background technology
The level gauge that measurement subtracts slag ladle uses differential pressure transmitter, and differential pressure transmitter is by differential pressure transmitter, capillary and band
Double flange three parts composition of bellows is sealed, the effect for sealing bellows is to prevent the medium in pipeline to be directly entered differential pressure transporting
Device, is connected between double flange film boxes and differential pressure transmitter by filling the capillary of liquid (generally using silicone oil)., will during work
The pressure medium of positive negative pressure pipe is delivered to positive pressure flange film box and negative pressure flange film box, and measured medium acts on double flange film boxes
Isolation diaphragm on, make diaphragm be pressurized after produce micro-strain because the difference of pressure tap, cause different deformation displacement or frequency
Rate passes to transmitter by the liquid of capillary, corresponding 4-20mA current signals is converted into after being handled by transmitter, most
Reflect the height of actual liquid level by the size of differential pressure eventually.
Existing alkaline residue tank differential pressure transmitter runs into relatively low temperature, double flange positive pressure pressure certain medias are easy without heat tracing
Congeal, cause instrument instruction rise；And since tank body is higher, alkaline residue component is mainly comprising dirts such as alkali, phenol, sulphur, COD, petroleum-types
Thing is contaminated, alkaline residue complicated component is various, and medium is dirty, easy crystallization, be easy to cause pressure Partial Blocking, causes to refer to alkaline residue tank liquid level
Show error.
The content of the invention
The shortcomings that the technical problem to be solved by the utility model is to overcome the above-mentioned prior art, there is provided one kind, which improves, to be situated between
Matter temperature, makes medium be not easy to crystallize, and clears up the coking material in pipeline in time, it is ensured that the utilization of the normal operation under low temperature environment is high
The device of the double Flange changer measurement alkaline residue tank liquid levels of warm steam.
Technical solution is used by solving above-mentioned technical problem：The lower part of alkaline residue tank passes through the positive pressure on pipeline
One end of pressure measuring valve and positive pressure flange film box is connected, and the other end of positive pressure flange film box passes through capillary and differential pressure transmitter
Positive pressure side is connected, and the negative pressure end of differential pressure transmitter is connected by one end of capillary and negative pressure flange film box, negative pressure flange
The other end of bellows is connected by the negative pressure pressure measuring valve on pipeline and the top of alkaline residue tank, the heating valve of installation the 1st
And the 2nd the heating tube of heating valve be wound on the pipeline between alkaline residue tank and positive pressure flange film box, purging valve is installed
Pipeline between heating tube and alkaline residue tank and positive pressure flange film box is connected.
The utility model, which is employed, winds heating tube progress steam on the pipeline between alkaline residue tank and positive pressure flange film box
Heating, it is possible to increase medium temperature, makes medium be not easy to crystallize, avoid congealing；Heating to pipeline is with being purged through heat tracing valve
The replacement to the heat tracing and purging function of pipeline is realized with the switch of purging valve, has been saved cost, has been simplified operation step
Suddenly, steam blowing can be periodically carried out to pipeline, the coking material of pipeline is cleared up in time, ensures that pipeline is unimpeded, it is ensured that to alkaline residue tank
The accuracy of level gauging.
