Abstract

The invention discloses a composite foul gas sensor detecting device which comprises a gas inlet unit, a sampling pool unit and a processing unit. The gas inlet unit is connected with the sampling pool unit which is connected with the processing unit. The gas inlet unit comprises two gas storage cylinders, a mass flow meter and a three-way valve. The sampling pool unit comprises at least one gas sampling module, a diaphragm pump, a sampling pool unit shielding wire and a power line. The gas inlet unit is used for providing detected gas with stable flow velocity and background gas with a flushing effect and ensuring the rapid switching of the detected gas and the background gas. A sensor for detecting foul gas and a signal conditioning circuit board matched with the sensor are put in the sampling pool unit so that complex foul components can be extracted and analyzed. The processing unit further processes signals collected by the sensor so that a gas reaction curve can be obtained and finally evaluates the concentration level of foul gas.

Description

technical field [0001] The invention relates to the field of environmental monitoring and control, in particular to a composite malodorous gas sensor detection device. Background technique [0002] Stench is a general term for various odors. There are many kinds of stench gases. The stench substances monitored and controlled by the current national standards are: carbon disulfide, dimethyl disulfide, hydrogen sulfide, trimethylamine, styrene, ammonia, methyl mercaptan and methyl sulfide. . With the development of the economy, people's awareness of environmental protection is constantly increasing. As a kind of environmental pollution, stench has been paid more and more attention by people. It is necessary to detect the stench, analyze the possible stench pollution, and put forward practical measures. To ensure that people have a comfortable air environment. [0003] One of the traditional odor detection research is "instrumental method (component concentration display meth...
