    1358527 Measuring liquid filterability ENTREPRISE DE RECHERCHE ET D'ACTIVITIES PETROLIERES (ELF) 6 Feb 1973 [28 Feb 1972] 5873/73 Heading G1N The index of filterability of a liquid, i.e. the temperature at which the flow rate of the liquid through a standard filter under a standard pressure drops below a given value, is measured automatically. In Fig. 1 the standard filter 18 divides test cell 16 into two chambers, the right hand chamber receiving a liquid such as fuel oil from constant pressure regulator 6 and the left hand chamber being connected to flow rate meter 11. The cell is surrounded by cooling bath 28 so that as liquid enters the cell it is cooled. When the flow drops below a pre-set rate, meter 11 passes a signal to gate 33 and this passes a signal from temperature sensor 20 in the cell to amplifier 35 and recorder 36. The meter signal also activates relay 22 and current is passed through a heating coil 27 around the cell for a predetermined time. This warms the liquid, flow increases, and the whole process repeats, the capacitor 34 storing the temperatures between each measurement. If the meter 11 is sensitive and the thermal lag of the cell is small, a series of temperatures which differ only slightly are recorded, Fig. 2, (not shown), and these give the index of filterability. The flow meter is preferably a float type rotameter (R.T.M.) with the float interrupting the path between a light source and a detector when the flow drops below a given value. The float position may alternatively be found magnetically. The flow may also be measured by a heated wire device or by determining the thickness of the flowing stream by its optical absorption, or by measuring the pressure across the filter. The cell may be cooled by a bath, by Pettier effect devices or a Ranque tube, while heating may be by wire or plate electric heaters, or by passing a current through the cell itself. The temperature sensor may be a thermocouple, a resistance probe or a transistor. The liquid to be tested has any impurities removed by a pre-filter 2 in Fig. 1, and water is removed by a coalexer 3.

    专利说明:

    The invention relates to the field of measuring the filterability index of liquid petroleum products and can be used in the refining and petrochemical industries.
    A device for measuring the filterability index of liquid fuel for engines, consisting of a test chamber, a calibrated filter, a flow detector, a temperature sensor installed in the test chamber [1].
    The disadvantage of this device is the discreteness of the measurements. And inconvenience in operation.
    The aim of the invention is to ensure continuity of measurement and ease of use.
    This goal is achieved by the fact that it additionally contains a control electromagnetic relay associated with a flow detector, a temperature control system of the test chamber, including a power source, a heating element, a cooling chamber and an analog matching circuit connected to the electromagnetic relay connected to the flow detector and temperature sensors and an information processing system associated with an analog match circuit.
    The drawing shows a block diagram of a device for measuring the filterability of liquid petroleum products.
    The apparatus consists of a camera test, a filtering baffle 2, the detector 3 flow, temperature sensor 4, the cooling chamber 5, the control of the electromagnetic relay 6, the power source 7, the heating element 8 Tel'nykh 3, the analog circuit 9 coincidence, the information processing system 10.
    The device operates as follows 5 .
    The tested liquid oil passes through the test chamber 1, separated by a filtering partition 2. In the process of passing the oil, the flow rate is measured by the flow detector 3 and the temperature by the temperature sensor 4 installed in the test chamber. The liquid oil product circulating through the chamber is cooled by the cooling chamber 5 5 to a critical filterability temperature, at which its flow through the filter baffle becomes practically negligible due to its clogging with paraffin hydrocarbons. The termination or reduction of the oil flow rate is detected by the flow detector, which gives a signal to the control electromagnetic relay 6, which connects the power supply 7 with the heating element 8. As a result, the test chamber is heated and paraffins dissolve, which clogged the pores of the filter material. At the same time, the flow detector supplies a trigger signal to the analog matching circuit 9, which allows storing values corresponding to the filterability temperatures.
    Thus, the temperature is memorized between the two measurements and the information processing processing system 10 fixes, which continuously records the temperature, starting from which the formation of crystallized particles in the product, in particular paraffins, leads to clogging of the standard filtering material to such an extent that the passage time of a given the flow rate of this product through the filter will be equal to or greater than the unit of time (1 min).
