Embodiment Construction
[0023] Such as figure 1 The high-temperature combustion microcoulomb analysis device for phosphate-resistant fuel oil chlorine content shown is mainly composed of three parts: a high-temperature furnace 2, a sampler 1 and an electrolytic cell 15. The combustion tube 14 is inserted in the high-temperature furnace, including the gasification section 13 and the combustion chamber. Section 12 has an oxygen port 7, a nitrogen port 5 and a sample inlet 6 on it. The sample injector includes a support, a slide rail 3 arranged on the support and a slide block 16 matched with the slide rail. The slide block 16 is fixedly connected to the pull rod 4, and one end of the pull rod 4 extends into the combustion tube 14 and is connected with a sample boat. . The electrolytic cell is generally arranged in a shielding box 8, which includes a pair of electrolytic electrodes 11, a reference electrode 9 and a measuring electrode 10, which cooperate to control the electrolytic process.

Thedevice comprises a high-temperature furnace and a burning tube inserted in the high-temperature furnace; the burning tube is provided with an oxygen interface, a nitrogen interface and a sample inletand comprises a gasifying section and a burning section, one end of the burning tube is connected with a sample inlet device, and the other end is connected with an electrolytic bath. The device adopts heating, gasifying and electrolytic analysis methods to obtain the chlorinity of a sample. The invention has simple and convenient operation and rapid analysis speed and adopts a microcoulomb method to analyze titration and judge the end point so as to be more accurate than the prior oxygen bomb method by visual inspection and manual measurement, have good test repetitiveness, avoid using toxicchemical reagents and improve the safety.
Description
ãTechnical fieldã [0001] The invention belongs to the field of power analysis chemistry, in particular to a high-temperature combustion microcoulomb analysis method for phosphate ester anti-fuel oil chlorine content. ãBackground techniqueã [0002] Due to its excellent flame retardant performance (generally, the self-ignition point is higher than 535°C), the phosphate ester anti-fuel is widely used in the electro-hydraulic speed control system of the thermal power generation unit. Chlorine content in phosphate ester anti-fuel is an important chemical indicator. Excessive chlorine content will cause corrosion and jamming of the servo valve of the speed control system, resulting in serious accidents. The chlorine content of new oil should not exceed 50mg / kg , The chlorine content of operating oil is required to be no more than 100mg / kg, so it is necessary to analyze the chlorine content of phosphate ester fuel oil. [0003] There are generally two methods for analyzing chlori...
