The application of flue gas analyzers in the chemical industry has been widespread and, as a process control instrument, has provided important data for the control and guidance of the chemical consumption process. Process control is made more timely and precise, and optimizes and maximizes the benefits of consumption. What should the choice of a suitable air analyzer be premised on? I. What gases are first to be detected by selecting a gas detector that understands one ' s needs? In what environment? Portable or fixed? And other side effects. These causes usually require reflection. Otherwise, it would appear that an oxygen detector was intended to buy an ozone detector, and that would cause a major urn, without delay, to cause unnecessary economic loss. II. UNDERSTANDING THE USE OF USE REQUIREMENT GAS Detectors

Owing to the diversity of the gases analysed and the diversity of the principles used for profiling, the flue gas analyzers are numerous. Thermal conductor flue gas analyzer, electrochemical smoke analyzer and infrared absorption profiler are commonly used. A pneumatic gas analyzer of a physical type, a thermoconductor. It calculates the content of certain components of the mixture based on the principle that different gases have different thermal conductivity. This is a simple and robust profile, with a larger variety of gases to be applied and a fundamental one. However, the direct calibration factor for the gas is difficult to compare, so it is common practice to convert changes in the gas-conductor coefficient to resistance changes, which are then measured by a bridge. Thermally sensitive elements of the thermal conductor flue gas analyzer are mainly semiconductor sensitive elements and metal electrical resistance wires. Semiconductor sensitive.

The sampling system for the flue gas profiler is divided into a routine sampling system and a heating sampling system. 1) Custom sampling systems: general choice of acid-resistant alkalis, high-temperature plastic tubes to ensure that gases are not adsorbed. Status of application: short-duration tests with low water content; Short-term testing of samples of gases without acid gases. 2) Heating sampling systems: this is the integration of heating functions based on the customary sampling system to ensure that the sample temperature is above 120°C during the sampling process, and that no water condensation is present during the sampling process. Status of application: sample tests with high water content; (b) Long-term online testing; Tests of acid gas content (e.g. NO2, SO2); 3 Pneumatic gas treatment systems: 1) soda separators: remove liquid moisture, first and foremost the handheld type selects this dewater treatment system.

Even though there are many brands of flue gas anatomy, either abroad or in the country, and you're too busy to pick out the smoke anatomy, so why do you choose to import the smoke anatomy? Portable pneumatic anatomy units are currently available on the market, usually in combination with electrochemical and infrared. The following is a brief description of how to select the flue gas profiler: 1, Sensors: The measuring units that are touched by the current dry flow flue profiler include, first and foremost, two sensors: 1) Electrochemical sensors: Strength: a small size: so hand-held machine types, typically electrochemical. b Cheap: a flue gas profiler that can be purchased for electrochemical sensors at a relatively low cost, if the budget is lower. Impairment: a slightly less accurate: general

The flue gas analysis system consists of two main functions: sample processing and sample analysis, which are installed in separate equipment and are internal to the catheters connected by cable fibre, electricity and wind. The two equipments are mounted in parallel on a general tube-like metal shelf. The separation of sample processing and analytical equipment has significantly reduced the erosion of H2S on electronic and electrical components. The flue gas analyzer measure H2S. UV rays absorbed in the electromagnetic spectrum by UV regions produces high and stable argon energy, transmitted back and forth through cable between measuring units. The radial length of the measurement unit is confirmed by the flow of acid sample gases. The light is passed through the cable to the measurement unit. After passing the gas cavity in the measuring unit, the remaining light is passed through the second cable to the spectrometer. Charge.

Gas treatment, gas pipeline transport, petrochemical, for mass and process manipulation purposes, require, secure, low-maintenance and cost-effective flue gas analyzers. The flue gas analyzer is an on-site validated flue gas analyzer, which adjusts process gases to 10 PSI after continuous online analysis of the principle of non-interference in lead acetic acid, then regulates sampling flows with fine flow calculations, and then transmits the sample gas to the lead acetic acid sensor belt. The signal was digitized by advanced microprocessors and related software, resulting in linear 4-20mA output, following the ratio of PVDDs and LED light system supply to H2S. Current readings, alert status, program tips, problem indicators, etc. are shown through the LCD Shower. The flue gas analyzer technology assures precision in a wide range of dynamics.
