Detailed Description
The utility model will now be described in detail with reference to the drawings and specific examples.
The technical scheme adopted for solving the technical problems is as follows: a rapid semi-quantitative analysis device comprises a cylindrical (D=12 cm, height H=30 cm) feed liquid container, a feed liquid inlet interface, a feed liquid outlet interface, a feed liquid inlet pneumatic control valve, a feed liquid outlet pneumatic control valve, a feed liquid container emptying filter, an air blowing instrument device, a differential pressure transmitter, a control station and a display device. The material liquid container is a place for placing material liquid to be measured, the material liquid inlet and outlet interface is a passage for feeding and discharging material liquid into and from the material liquid container, the material liquid inlet and outlet control pneumatic valve controls the material liquid to enter and exit the material liquid container, the air blowing instrument device and the control station measure the liquid level and density of the material liquid, and calculate phi (TBP)%, and the display device displays the analysis test result. The upper end of the feed liquid container is provided with a feed liquid inlet interface, a feed liquid inlet pneumatic control valve, a blowing instrument pipeline interface, a feed liquid container emptying pneumatic control valve and a feed liquid container emptying filter, the lower end of the feed liquid container is provided with a feed liquid discharge interface and a feed liquid discharge pneumatic control valve, and the lower end of the feed liquid container is provided with a semi-ellipsoidal seal head, so that the feed liquid is conveniently and thoroughly discharged. The liquid level h is controlled by interlocking with a feed liquid inlet pneumatic control valve and a feed liquid container air discharge pneumatic control valve, and when the liquid level h reaches 20cm, the feed liquid injection control valve is automatically closed.
The feed liquid container of the device is cylindrical, and feed liquid enters the feed liquid container through the feed liquid inlet. Before the feed liquid is injected into the container, the blowing instrument device is started, and the liquid level h of the feed liquid in the container and the density rho of the feed liquid are measured through the blowing instrument device. The radius of the feed liquid container in the device is 6cm, the liquid level height after the feed liquid is injected is h.cm, and the volume of the feed liquid (pi is taken to be 3.14) entering the container is 113.04 h.cm 3 Wherein the volume of TBP is x cm 3 TBP density of 0.979g/cm 3 Hydrogenated kerosene with volume of (113.04 h-x) cm 3 Hydrogenated kerosene with a density of 0.80g/cm 3 . After the density rho of the feed liquid is calculated by the air blowing instrument device and the control station, the volume fraction phi (TBP)% of TBP in the feed liquid can be calculated according to a program. The principle on which the program is calculated is as follows:
φ(TBP)％＝(ρ-0.80)/0.179
wherein the density ρ of the feed liquid can be measured by the blow meter device and the control station. After the feed liquid is analyzed, the feed liquid enters a feed liquid conveying pipeline through a feed liquid outlet discharge device and enters other storage containers, and the one-time analysis process is completed. In the single analysis process, except that the injection and the discharge of the feed liquid take a few minutes, the occupied time of the rest steps can be ignored, and the whole analysis process is long-distance operation, so that the aim of rapid long-distance semi-quantitative analysis of TBP in TBP-OK solution can be fulfilled. It is to be noted that the densities of TBP and kerosene involved in the calculation process of the device are both the density values of pure TBP and kerosene, and the influence of irradiation on the densities is not considered in the use process; the influence of the existence of micro-splinter elements on the density of the TBP-OK solution is not considered; default TBP-OK solution is single phase mixed evenly; in order to verify the accuracy of the blowing instrument, the blowing instrument needs to be corrected by standard substances in the early stage; although the TBP content analysis of the device is irrelevant to the liquid level h of the feed liquid, in order to ensure that the liquid level h of the feed liquid in a feed liquid container is at a proper position, the device still needs to measure the liquid level h of the feed liquid through a blowing instrument.

The electrical signal of the differential pressure transmitter 6 is analyzed by the control station 7 and the set algorithm phi (TBP)% = (ρ -0.80)/0.179 to obtain the analysis result. The liquid level h is controlled in linkage with the feed liquid inlet pneumatic control valve 3, and when the liquid level h reaches 20cm, the feed liquid inlet pneumatic control valve 3 is automatically closed.
