Problems solved by technology

These two reasons cause the temperature in the receiving cell to change, so that the temperature of the analytical gas flowing through the receiving cell changes, and the flow rate also changes accordingly. The electrical signal fed back by the pyroelectric sensor is unstable, resulting in long-term inaccuracy of the test results. poor stability

Embodiment Construction

[0011] In combination with the structural schematic diagram, the specific implementation manner of the present application will be described as follows.

[0012] The infrared carbon-sulfur analyzer comprises a receiving pool 2, the receiving pool 2 is connected to the air inlet pipe 7 and the outlet pipe 6, and a constant temperature device is set in the infrared carbon-sulfur analyzer, and the gas chamber constant temperature device includes a heat preservation chamber 1, an air supply Heater 3 and thermostat probe 4 for heat supply in insulation chamber 1; described receiving tank 2, temperature controller probe 4 and heater 3 are all arranged in insulation chamber 1, and air supply pipe 7 and The hole that air outlet pipe 6 enters and exits. Heating by the heater increases the temperature of the heat preservation chamber, and the thermostat probe 4 inputs the electrical signal of the induced temperature into the heater 3. When the temperature of the heat preservation chambe...

Abstract

The invention discloses an infrared carbon and sulfur analyzer provided with a constant-temperature device. The infrared carbon and sulfur analyzer comprises a receiving tank, wherein the receiving tank is connected with a gas inlet pipe and a gas outlet pipe; the infrared carbon and sulfur analyzer is internally provided with the constant-temperature device; the constant-temperature device comprises a heat preservation room, a heater and a temperature controller probe; the receiving tank, the temperature controller probe and the heater are arranged in the heat preservation room; and the heat preservation room is provided with holes for the gas inlet pipe and the gas outlet pipe to get in and out. The receiving tank is arranged in a constant-temperature environment so that on one hand, the influences on the receiving tank by the external environment are avoided, and on the other hand, a standard temperature in the receiving tank is improved; even if heat generated by an infrared light source in the receiving tank can increase the temperature in the receiving tank, the whole change of the temperature in the receiving tank is not great, so that the temperature change of analyzed gas flowing through the receiving tank is not great and the flow change is not great; and an electric signal fed by a pyroelectric sensor is relatively stable so that the long-period stability of the measurement of the infrared carbon and sulfur analyzer is improved.

Description

technical field [0001] The present application relates to a carbon and sulfur analyzer, in particular to an infrared carbon and sulfur analyzer equipped with a constant temperature device. Background technique [0002] At present, there are many kinds of analytical instruments for analyzing the carbon and sulfur elements in materials at home and abroad. Among them, due to the use of infrared methods to determine the amount of carbon and sulfur, infrared carbon and sulfur analyzers are economical, environmentally friendly, fast in analysis speed, high in sensitivity and wide in measurement range. Wide, wide application and other advantages. [0003] Patent No. 201120118182.4 records a high-frequency infrared carbon-sulfur analyzer. Its working principle is: after the sample is heated and melted in the high-frequency induction furnace, it is sent into the combustion chamber, and after being burned in the combustion chamber, it is sent into the infrared Carbon and sulfur analy...
