Oxygen content detector

Abstract

The invention relates to the technical field of gas analysis equipment, in particular to an oxygen content detector, comprising a box body, a sampling probe, a water storage filter, a gas diaphragm pump, a condenser, a sampling flow meter, an emptying flow meter, a fine filter, an oxygen detector, a controller, a centrifuge frequency converter and an electromagnetic valve, wherein the sampling probe is arranged in a process pipeline; the water storage filter is arranged in the box body and is connected with the sampling probe; the gas diaphragm pump is arranged in the box body and is positioned on a pipeline between the sampling probe and the water storage filter; the condenser is arranged in the box body and is connected with the water storage filter; the sampling flow meter is arranged in the box body and is connected with the condenser; the emptying flow meter is connected with the sampling flow meter; the fine filter is connected with the sampling flow meter; the oxygen detector isconnected with the fine filter and is used for performing oxygen content analysis; the controller is in data connection with the oxygen detector; the centrifuge frequency converter is connected withthe controller; the electromagnetic valve is arranged at a pipe orifice of a nitrogen source and is connected with the controller. The sample gas treated by the oxygen content detector is dry, stableand accurate in measurement; the oxygen content detector can realize automatic feedback and control, thus being safe and reliable.

Description

technical field [0001] The invention relates to the technical field of gas analysis equipment, in particular to an oxygen content detector. Background technique [0002] Process analytical instrumentation for measuring gas composition. In many production processes, especially in production processes with chemical reactions, automatic control based on physical parameters such as temperature, pressure, and flow is often not enough. Due to the wide variety of analyzed gases and the variety of analysis principles, there are many types of gas analyzers. Commonly used are thermal conductivity gas analyzers, electrochemical gas analyzers and infrared absorption analyzers. [0003] Due to the variety of materials handled by the centrifuge, and many of them are flammable and explosive, it is easy to cause combustion and explosion accidents. Oxygen in the centrifuge is inconvenient to detect, and the oxygen content exceeds the standard and is unsafe. The existing pretreatment is a ...

Problems solved by technology

[0003] Due to the variety of materials handled by the centrifuge, and many of them are flammable and explosive, it is easy to cause combustion and explosion accidents.

Oxygen in the centrifuge is inconvenient to detect, and the oxygen content exceeds the standard and is unsafe. The existing pretreatment is a simple pump with absorbent cotton, which cannot remove material pollutants, cannot automatically control and replenish nitrogen, and replace high-concentration oxygen automatically. stop centrifuge
