The invention discloses a sulfur determination instrument with an air tightness detection device, which includes a furnace body fixed on the bottom plate, a control mechanism, an electrolytic cell, a drying device and a pump connected in sequence through pipelines, and a combustion chamber installed in the furnace body. The electrolytic cell is connected to the tail end of the combustion tube through a pipeline. The inlet end of the furnace body is provided with a sample delivery nozzle, which is connected to the sample delivery device. The ventilation pipeline between the furnace body and the pump is provided with a gas A tightness detection device, the airtightness detection device includes an airtight mechanism located on the pipeline between the combustion tube and the electrolytic cell, and a flow detection mechanism located at the outlet of the electrolytic cell or the drying device, and the flow detection mechanism is connected with the control mechanism. The invention is a simple and compact structure, low cost, capable of automatically detecting the airtightness of the ventilation pipeline, making accurate judgments on the airtightness of the entire airway, thereby ensuring the accuracy of the test results with airtightness detection The sulfur meter of the device.
Description
technical field [0001] The invention mainly relates to the field of measuring equipment for sulfur content in combustible substances, in particular to a sulfur determination instrument with an air tightness detection device. Background technique [0002] Sulfur is the most important harmful component in coal samples. It mainly exists in coal in the form of elemental sulfur, sulfide and sulfate. The sulfide contained in coal will generate harmful SO after combustion. 2 and SO 3 Gas and fly ash are discharged into the atmosphere along with flue gas, causing air and environmental pollution. Therefore, the detection of sulfur content in coal samples is a very important task for coal production, sales, use, and environmental protection departments. In the prior art, in order to accurately and quickly measure the sulfur content in combustible substances, a sulfur meter is generally used as a common measuring device. In various measuring equipment, such as sulfur meter, etc., the...
