Online analysis system for ethylene oxide gas

Online analysis system for ethylene oxide gas

The online smoke monitoring system routinely monitors sulfur dioxide (SO2), nitrogen oxides (NOX), oxygen (O2), temperature, pressure, and flow rate. Regular maintenance is *, below are the specific inspection and operation procedures.

1. Inspection personnel must undergo training and obtain an operation and maintenance certificate before they can operate on duty.

2. Inspection and maintenance personnel must strictly comply with the rules and regulations of the testing equipment user unit.

3. Every morning and afternoon, the operation status of the instrument is remotely detected through unlimited transmission to check if the data transmission system is normal. If any continuous abnormal data is found, the station should be immediately inspected.

4. Strictly follow the equipment manual for use and maintenance operations.

5. Regular weekly inspections are conducted, and the inspection procedures include necessary inspection items such as the operation status of wireless upload equipment, smoke CEMS work, operation status of system paving equipment, system calibration work, as well as other inspection items and records specified in the instrument manual.

6. On site inspection content:

(1) Determine the operating status and main technical parameters of the smoke CEMS monitoring instrument, pitot tube, dust meter, and data acquisition and transmission instrument to determine if they are operating normally.

(2) Observe the operation of the data transmission and acquisition instrument, check for any damage at the connection, and inspect the data. Compare the data received by the CEMS flue gas online monitoring instrument, data acquisition and transmission instrument, and upper computer to ensure accuracy.

(3) Check for leaks in the smoke sampling collection pipeline and pre-treatment gas path.

(4) Inspection and maintenance of sample gas sampling probe and particulate matter (dust analyzer): Check whether the sample gas sampling probe is loose and whether the heating system is normal. Regularly clean or replace the sampling probe filter element based on on-site usage (approximately every three months for inspection). During power outages or shutdowns, it is also necessary to inspect each filter element, or clean or replace it. Clean the isolation smoke and optical probe glass window (mirror) of the particulate matter online monitoring instrument once a month, and the specific cleaning time depends on the on-site conditions.
