Solution for volatile organic gas detector in furniture factory

1、 Analysis of VOCs exhaust gas characteristics in furniture factories

1. Source of exhaust gasMainly from spray painting rooms, painting workshops, paint mixing rooms, drying areas, bonding workshops, etc.

2. main ingredientsVolatile organic compounds such as benzene, toluene, xylene, formaldehyde, ethyl acetate, acetone, etc.

3. The emission characteristics include:

   • 1. The concentration fluctuates greatly,During processes such as painting and drying, the concentration sharply increases and intermittent emissions occur.

   • 2. Flammable and explosive,Some VOCs gases are flammable substances that accumulate in enclosed spaces and pose a risk of explosion.

   • 3. Toxic and harmful,Benzene, formaldehyde, and other known carcinogens pose great health risks to employees.
     

2、 Principles of Solution Design

• Safety firstPrevent fire, explosion, and personnel poisoning accidents.

• complianceMeet the requirements of national and local environmental regulations and occupational health standards.

• Hierarchical classificationConfigure detectors with different functions and accuracy levels based on the risk level of different regions.

• Real time and reliableEnsure accurate detection data, timely alarms, and stable system operation.
  

3、 Partition detection scheme configuration

According to the risk level, the factory area is divided into different regions and different detection strategies are adopted:

4、 System functions and linkage control (core advantages)

Simple detection and alarm are the foundation,The essence of the solution lies in the linkage control with governance facilities.

1. Automatic start/stop ventilation：

   • When the reading of the detector exceeds the preset alarm value of level one, the system automatically starts the exhaust and supply systems to forcibly dilute harmful gases in the area.

2. Automatically cut off the source of danger：

   • When the reading of the detector exceeds the second level preset alarm value, the system automatically interlocks to cut off the power or gas supply for the painting operation, terminating the leakage from the source.

3. Sound and light alarm prompt：

   • Install explosion-proof sound and light alarm lights on site to remind staff to evacuate quickly. The central control room monitoring screen pops up an alarm message and records the event.

4. Data recording and remote monitoring：

   • All detection data is uploaded to the PLCCentral Control RoomThe monitoring software platform enables 24-hour uninterrupted monitoring, historical data query, and report generation, meeting safety and environmental audit requirements.
     

5、 Suggestions for instrument technology selection

1. detection technologyPID (photoionization detection)Device: Preferredtechnology It has high sensitivity and fast response speed to the vast majority of VOCs, making it very suitable for leak detection and occupational health and safety protection.

6、 Implementation and maintenance

1. Layout designScientifically design installation points and heights based on gas density (heavier or lighter than air), ventilation conditions, and release source location.

2. Regular calibration and calibrationThis is the key to ensuring accurate data. Usually, standard gases are used for calibration every 6 months to 12 months.

3. Sensor lifespan managementPID lights and sensors have a lifespan and require regular inspection and replacement.

4. personnel trainingProvide professional training for operation and maintenance personnel to ensure that they are proficient in using, judging, and emergency response.
