Second valve switch is set on two pipelines.
Reactor bottom is the high viscosity liquid phase with solvent, and top is gas phase, under the action of condenser, vapor phase solvent
It liquefies within the condenser, since the first pipeline is in tilted layout, the vapor phase solvent after liquefaction flows into liquid level gauge, liquid certainly along the first pipeline
Liquid level is higher than liquid level in reaction kettle in the meter of position, and according to law of connected vessels, liquid level is calculated as keeping liquid level constant, by liquid level
Meter bottom liquid phases are expelled to reaction kettle, and since vapor phase solvent viscosity is small, the liquid phase viscosity after liquefaction is low, to liquid phase in liquid level gauge
Diluting effect is played, and then realizes the level gauging of high-viscosity material.
Described, the angle that the first pipeline tilts down in the horizontal direction is 2-5 degree.
It is flowed into liquid level gauge convenient for the gas phase after liquefaction.
Described, liquid level gauge top nozzle, liquid level gauge bottom nozzle are respectively provided with triple valve, the both ends of the differential pressure transmitter
It is connected respectively with corresponding triple valve valve port.
When normal measurement, the pressure difference for the differential pressure transmitter detection differential pressure transmitter both sides being connected to triple valve valve port is used for
The output of liquid level data；When liquid level gauge is cleaned and purged, turns off triple valve valve port, the first valve being connect with differential pressure transmitter and open
It closes, the second valve switch, the valve port being not turned off by triple valve is cleaned and purged to liquid level gauge.
The utility model has the beneficial effects that：
(1) the high viscosity liquid level emasuring device described in the utility model containing solvent is provided with condenser and the first pipe
Road makes the vapor phase solvent on reaction kettle top liquefy and flows automatically into liquid level gauge, plays circulation flushing function to liquid level gauge, and then realize
The level gauging of high-viscosity material；
(2) the high viscosity liquid level emasuring device described in the utility model containing solvent is provided with the first valve switch,
Two valve switch, triple valve realize the dredging and cleaning of liquid level gauge by turning off corresponding valve port.
