Abstract

The invention discloses a neutralization method sulphur meter with a sodium hydroxide calibration function, and belongs to the technical field of automatic metering devices for measuring sulfur content in coal. The neutralization method sulphur meter comprises a combustion oven and a sodium hydroxide calibration device both fixed on a base plate, a combustion pipe arranged in the combustion oven, a nickel chromium push bar arranged in the combustion pipe, an air pump, an oxygen tank and a beaker. Two ends of the combustion pipes are respectively connected with the beaker and the oxygen tank via air ducts, and the air pump communicates with inside of the beaker via an air duct. The sodium hydroxide calibration device comprises an L-shaped bracket installed on the base plate, a high-definition camera head arranged on a camera head bracket, a beaker containing sulfuric acid solution, a base on which is installed a measuring cylinder, a worm arranged between the left support and the right support, a worm gear engaged with the worm, and a stepping motor installed on a motor bracket. The invention relates to the neutralization method sulphur meter with a sodium hydroxide calibration function, a high automation degree and a simple structure.

Description

technical field [0001] The invention mainly relates to the field of automatic measuring equipment for sulfur content in coal, in particular to a neutralization method sulfur measuring instrument with a sodium hydroxide calibration function. Background technique [0002] Sulfur is very harmful to coal coking, gasification, and combustion, so it is necessary to quickly and accurately measure the content of sulfur in coal. As one of the rapid determination methods of total sulfur in coal, the high-temperature combustion neutralization method can obtain the test results in a short time. At present, most of the domestic neutralization methods use manual operation: the coal sample is burned in an oxygen flow under the action of a catalyst to generate sulfur oxides, which are trapped in a hydrogen peroxide solution to form sulfuric acid, and the sodium hydroxide solution is manually operated to make it Neutralize with sulfuric acid solution, and calculate the total sulfur content ...
