The utility model relates to a kind of sulphur meter, is specially adapted to the sulphur surveying instrument with heating arrangement.
Background technology
The sulphur meter that the utility model relates to is the sulfur content detected according to coulometric titration in coal.The principle of work of coulometric titration is: coal sample is under catalyst action, combustion decomposition in air stream, in coal, sulphur produces oxysulfide, its sulphur oxide is absorbed by liquor kalii iodide, the iodine produced with electrolysis liquor kalii iodide carries out titration, according to the content of the electricity calculating full content of Sulphur in coal that electrolysis consumes.
Usually, sulphur surveying instrument is made up of main frame, pyrolysis furnace, electrolytic cell, electromagnetic pump and air cleaning system.Main frame is the operation control system of sulphur surveying instrument, for setup parameter, process experimental data and display measurement result.Electromagnetic pump is supplied gas and is entered air cleaning system, and removal water and purifying air of sour gas enter pyrolysis furnace as carrier gas.Coal sample is burnt and is generated oxysulfide in pyrolysis furnace.Oxysulfide enters electrolytic cell with carrier gas, and destroys electrolysis mobile equilibrium.Host record electrolysis power consumption, and the convert corresponding sulfur content of acquisition and percentage composition.
Wherein, the pyrolysis furnace of sulphur surveying instrument has a heating arrangement, and its heating-up temperature can reach more than 1150 DEG C, decomposes coal sample with high-temperature heating.At present, the general two screw thread carborunbum tubes of a terminated line that adopt are as heating element.Flame tube adopts quartz ampoule, directly puts into carborunbum tube and heats.But carborunbum tube exists following defect as heating element in above-mentioned application: 1) carborunbum tube matter is crisp easily broken, easily rupture when being given a shock and clashing into; 2) the easy loose contact sparking of the lug plate of carborunbum tube; 3) the high-temperature constant warm area of carborunbum tube is shorter, only has about 70mm.
Utility model content
The purpose of this utility model is: provide a kind of sulphur meter with New Heating.
The technical solution of the utility model is: a kind of sulphur meter with New Heating, heating arrangement comprises combustion chamber body and electric furnace heating wire, combustion chamber body has through inner chamber, inner chamber is divided into low temperature cavity and high temperature chamber, the sidewall in high temperature chamber offers thermometer hole, electric furnace heating wire around or be arranged in the region in high temperature chamber, and to be partly exposed in high temperature chamber.Wherein, combustion chamber body adopts high-temperature refractory manufacture, such as aluminium oxide, ceramic fiber etc.; The maximum heating temperature of electric furnace heating wire can reach more than 1150 DEG C, such as, with the electric furnace heating wire that the materials such as ferrum-chromium-aluminum, molybdenum chromium aluminium manufacture.
In certain preferred embodiment, through inner chamber inner chamber is convenient to insert reducing flame tube.
In certain preferred embodiment, the coated muff in outside of combustion chamber body, and muff offers through hole in the position of corresponding thermometer hole.Be conducive to the insulation of combustion chamber body like this.
In certain preferred embodiment, heating arrangement also comprises one can to the thermopair of high temperature chamber thermometric, and it inserts thermometer hole by through hole.
In certain preferred embodiment, electric furnace heating wire is spirally surrounded on the region in high temperature chamber.In an additional preferred embodiment, electric furnace heating wire is parallel to the region in high temperature chamber along the axis of combustion chamber body.Being designed with like this helps electric furnace heating wire uniformly transfer heat, keeps the temperature of flat-temperature zone, high temperature chamber.
In certain preferred embodiment, electric furnace heating wire draws wiring from one end of combustion chamber body.
Usefulness of the present utility model is: sulphur meter replaces carborunbum tube as heating arrangement using electric furnace heating wire combustion chamber, and the material of combustion chamber body and electric furnace heating wire is not easily broken, can avoid frequent replacing, is beneficial to equipment continuity and uses; Electric furnace heating wire wiring is simple, and contact is good, can avoid striking sparks; The high-temperature constant warm area of electric furnace heating wire combustion chamber can reach about 120mm, is longer than the region of the 70mm of carborunbum tube.
