Embodiment Construction

[0016] As shown in the figure, the rhodium-hydrocarbon electrolytic cell is mainly composed of a cell body 1, a rhodium wire 2 and a cooling sleeve 3. The cell body is a glass tube with openings at both ends. There are two rhodium wires, which are not connected to each other, and are wound in parallel and spirally. On the inner wall of the cell, there is a phosphorus pentoxide coating film on the surface. The weight ratio of phosphoric acid and acetone contained in the film is 3:7. The rhodium wire passes through the glass tube wall and is connected to the positive and negative electrodes 4 and 5 respectively. In this example, the inner diameter of the glass tube is 6mm, the wall thickness is 2mm, the total length (including the air outlet) is 180mm, the diameter of the rhodium wire is 0.5mm, the length of each rhodium wire is 1.5m, the distance between two rhodium wires is 0.5mm, and the outer diameter of the cooling jacket is 24mm. There is a sealing ring at the junction with...

Abstract

The invention discloses a rhodium-hydrocarbon electrolytic bath which mainly comprises a bath body, two rhodium wires and a heat dissipation sleeve, wherein the bath body is a glass tube with two open ends; the rhodium wires are coated with phosphorus pentoxide films, are parallelly and spirally wound on the inner wall of the bath body and are disconnected from each other; the heat dissipation sleeve is mounted at the periphery of the bath body; and a water inlet and a water outlet are formed in two ends of the heat dissipation sleeve. The rhodium-hydrocarbon electrolytic bath serves as the core component of a coulometric analysis meter, is used for measuring the moisture content in various materials such as coal, oil, soil and cement, has a simple structure, stable properties and a long service life, and is easy to manufacture, convenient to use, and quick and accurate in measuring.

Description

technical field [0001] The invention relates to an electrolytic cell for a coulometric analysis instrument, in particular to a rhodium-hydrocarbon electrolytic cell for measuring the moisture, hydrogen and carbon contents in various materials such as coal, oil, soil and cement. Background technique [0002] The content of carbon and hydrogen is an important indicator for evaluating petroleum, coal and other materials, and it is of great significance for understanding the metamorphic properties of coal, oil and their products and studying the structure of organic matter. Accurately measure the hydrogen content in coal and oil products, which can be directly used to calculate the low level and net calorific value. [0003] The classic measurement method is the absorption method for the determination of hydrocarbons, which belongs to the chemical method. The equipment used for this method is huge, the operation is time-consuming and laborious, the calculation is troublesome, th...
