Hydrogen sulfide analyzer

Abstract

The invention relates to the technical field of hydrogen sulfide analyzers, in particular to a hydrogen sulfide analyzer which comprises an analysis device, a content proportioning device is fixedly connected to the top of the analysis device, and a second gas inlet pipe device and a first gas inlet pipe device are arranged on the left side and the right side of the top of the content proportioning device respectively. When air pressure in a pressure adjusting pipe enters an inner cavity of the filtering device, the air pressure enters a hollow flow dividing groove through a pipeline mounting hole, and at the moment, air flow in the hollow flow dividing groove is dispersed into a plurality of second flow dividing grooves from an arc-shaped air outlet plate; in this way, the gas can be further filtered through adsorption carbon plates arranged on the multiple arc-shaped filter plates and the isolation plate, the matching pipe conveys external pure water vapor into the annular gas collection cavity, the detected sulfuration gas is mixed with the vapor, the humidity of the gas analyzed in the later period can be increased, and the detection accuracy is improved. And the hydrogen sulfide can be kept in a pure state, so that the detection accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen sulfide analyzers, in particular to a hydrogen sulfide analyzer. Background technique [0002] Hydrogen sulfide is an inorganic compound with a molecular formula of H2S and a molecular weight of 34.076. It is a flammable acid gas under standard conditions. poison. The aqueous solution is hydrosulfuric acid, which is weaker than carbonic acid but stronger than boric acid. Soluble in water, easily soluble in alcohols, petroleum solvents and crude oil. Hydrogen sulfide is a flammable and hazardous chemical, which can form an explosive mixture when mixed with air, and can cause combustion and explosion when exposed to open flames and high heat. Hydrogen sulfide is an important chemical raw material. [0003] Hydrogen sulfide is a common toxic gas in the chemical and petroleum fields. Generally, in the process of chemical production, an analyzer is installed on the chemical raw material production...

Problems solved by technology

[0003] Hydrogen sulfide is a common toxic gas in the chemical and petroleum fields. Generally, in the process of chemical production, an analyzer is installed on the chemical raw material production line or on the reactor, which is used to detect hydrogen sulfide in real time. Existing When the hydrogen sulfide analyzer is in use, after the chemical gas is connected, when the gas passes through the lead acetate, the paper tape produces a discoloration reaction, so that the brown depth of the discolored area on the paper tape can be used to analyze the content of hydrogen sulfide, but In the process of actual analysis, especially when the above-mentioned method is used for detection, there will be the following problems. The connected gas contains impurities, which makes the internal impurities accumulate in the lead acetate box when the impure gas passes through the analyzer, which affects the reaction of the reactant. The quality of the internal impurities makes it difficult to clean up, and the pressure of the gas will fluctuate. The existing analyzer cannot be calibrated in real time, so the air pressure entering the lead acetate is either large or small, so the reaction is not sufficient, and the gas in the gas Poor humidity will lead to inaccurate analysis, and internal acetic acid needs to be added regularly, which will increase the workload of operators.
