SU1550399A1 - Device for monitoring purity of hydrocarbon fuel in flow - Google Patents

Abstract

The invention relates to the means of dielectric control of multicomponent mixtures, in particular, emulsion water and mechanical impurities, in a stream of hydrocarbon fuel and can be used in the petrochemical and petroleum refining industry, as well as in aircraft transport in systems for centralized refueling of aircraft. The aim of the invention is to improve the accuracy with selective quantitative control of emulsion water and solid impurities. The selectivity is achieved by the fact that in the measuring path downstream a pulsed primary transducer (PP) of a capacitive type, a liquid preheater and a second PP are installed, identical to the first. The outputs of the PCB are connected to a differential pulse counter. Information about the presence of mechanical impurities and emulsified water comes from the PP, after passing the preheater, the latter is completely dissolved in the liquid, the second PP determines only the presence of solid particles, the difference in the measured number of pulses determines the content of emulsion water. 1 hp f-ly, 1 ill.

Description

non-uniform inclusions in the fuel, heater 3 fuel8 additional PP 4 identical to the first, regulation 5, counter 6 pulses made in a differential circuit. Fluid flow rate is kept constant. Output PP 2 is connected to the first input of the differential counter 6 pulses output PP 4 - respectively to the second input of the counter 6 pulses.

A version of the device is made in the form of a parallel circuit, when П1Т 2 and ПИ 4 are installed on parallel bypass pipelines, and fuel heater 3 is installed in front of the flow entrance to one of the converters.

The device works as follows.

 The flow of the analyzed fluid containing emulsion water and mechanical impurities enters the air separator 1, where air bubbles are removed from it. Next, the liquid enters first into PP 29 and then through the fuel heater 3 into PP 4. In PP 2, pulses are formed, the number of which The number of particles of emulsion water and mechanical impurities. In the preheater 3, the liquid heats up and the emulsion water goes into the dissolved state. Therefore, impulses are formed in PP 4, the number of which is determined only by mechanical particles.

impurities. The readings of PP 2 and PP 4 are read by a differential counter of 6 pulses made, for example, on the basis of a reversible counter, and judging by the difference of the content of emulsion water in the fuel.
