RTO waste gas VOCs concentration online detection system

VOCs in RTO exhaust gasThe ingredients are complex and usually associated withSpecific industries and production processesClosely related. Understanding these components is the foundation for selecting subsequent processing techniques and testing methods.

Common VOCs typesFrom a chemical structure perspective, VOCs mainly include alkanes, alkenes, aromatic hydrocarbons (such as benzene, toluene, xylene), etchydrocarbonsKetones (such as acetone), esters, aldehydes (such as formaldehyde), etcOxygen-containing organic compoundsAnd organic compounds containing chlorine, sulfur, nitrogen, etc-

• Industry emission characteristics：

• Chemical and pharmaceutical industriesWaste gas often contains various solvents such as benzene derivatives, halogenated hydrocarbons, alcohols, and ethers. It should be noted that certain materials, such as acrylonitrile and styrene, may experience temperature fluctuations at high temperaturesself-aggregationThis may increase the resistance of the RTO furnace's thermal storage ceramic body or cause high boiling point organic matter to adhere to the bottom, posing a safety hazard-.

• Tape and coating industryIn addition to the main organic solvents (such as toluene), there may also be accompanying factors during the coating and drying processesHigh boiling point compoundEmissions. For example, a certain tape manufacturer's exhaust gas was found to contain plasticizer DINP (diisononyl phthalate), which is prone to cooling and forming small oil mist during transportation, and may condense on RTO heat exchange bricks, causingcokingIt affects normal operation.

  Printing and spraying industryThe main emissions come from VOCs such as benzene derivatives, esters, and ketones in inks, diluents, and cleaning agents.
  

• Wastewater and solid waste treatmentThe VOCs generated are complex in composition and may include hydrogen sulfide, thiols, amines, etcOdorous substancesIt has the characteristics of multiple emission points and unorganized emissions.

  Here is a brief introduction using a customized physical image from a customer as an example

  

withHoneywell fixed VOC gas detectorFor example,HoneywellRAEGuard 2 PIDIt is an organic gas detector with a flameproof host, intrinsic safety photoionization intelligent sensor, and fixed installation method. The instrument adopts an intelligent processing platform and digital sensor technology, which realizes offline calibration of sensors and environmental adaptation functions. It can also customize different ranges according to user requirements. In terms of external functions, the detector has functions such as graphic display and local sound and light status indication. At the same time, the detector adopts a three key magnetic rod external adjustment method, allowing operators to easily calibrate and maintain on site without opening the cover.
