GDB2-VOC online monitoring system

GDB2 VOC online filter monitoring system can be used to detect the concentration of VOC gas(O2,CO2,H2S and other gases can be customized). Once the gas concentration exceeds the standard, it will give an alarm. It can accurately detect the concentration of VOC gas and display the real-time concentration value and standard signal output on site. The advantages of stable signal, high sensitivity and precision, flameproof wiring are suitable for various dangerous places.

GDB2 VOC online filter monitoring system is suitable for environmental protection and safety, petrochemical, steel smelting and other industries and departments. It can be used in petrochemical, organic chemical, pharmaceutical manufacturing, industrial coating, mechanical equipment manufacturing, packaging and printing, electronic production, Real-time online monitoring in various complex environments in synthetic leather, coatings and paints, clothing processing, furniture manufacturing, adhesives and other industries.

GDB2 VOC online filter monitoring system adopts the internationally renowned high-precision PID photoion detection principle, built-in suction pump working mode, fast response time; high precision, long life; wide detection gas range; strong anti-interference ability; 4- Standard signal output such as 20mA, RS485/M-BUS, etc., can be easily integrated into the monitoring system. Two-level switch output; on-site LCD display, infrared remote control external adjustment and setting; can transmit the vocs gas in the environment with electrical signals remotely, and transmit the signal to the secondary instrument, the sensor can be directly uploaded to the computer, Or connect to the DCS system. It can also be connected with the environmental monitoring platform of the local environmental protection bureau to achieve continuous remote monitoring of the total volatile organic compound (VOCS) concentration in the environment.

The GDB2 VOC online filtering monitoring system product has the functions of on-site buzzer indicating sound, on-site flashing indicator, and real-time display and monitoring of on-site VOC concentration.

 

Pressure adjustment:

Part of the on-site environmental pressure is a very pressure environment (101 KPa), and the pressure of the environmental sampling port needs to be adjusted before sampling. (This processing unit is an external unit, adjusted according to the on-site environment, suitable for positive pressure or negative pressure in the sampling environment)

 

Dust removal:

 

Dust removal filter adopts vacuum pump filter, which is widely used in industrial vacuum system to effectively prevent solid particles or dust from being sucked into the vacuum pump or system. Reduce pump wear, improve pump reliability, extend pump life, and effectively protect the components of the vacuum system.

The filter adopts all-steel structure, sturdy and durable. It is suitable for industrial use. The answer and request adopts a seamless stretched metal shell, equipped with a copper welded port, which has high air tightness and large scale capacity, easy to clean, and simple and quick to replace the filter element. The inlet and outlet are connected by thread, and special nozzles can be fitted according to customer requirements. The filter is sealed with O-rings, and the maximum vacuum value is less than 1Pa. The standard configuration paper filter element, the filtration accuracy is 99% (10 micron particles), and the passing gas temperature is -15° to 90°.

 

Cool down:

 

 

The cooling device of this system is a physical cooling condenser and does not have a cooling function. The condenser adopts a copper tube design with strong thermal conductivity and hydrophilic fins, which effectively enhance the heat dissipation effect.

 

Water filtration:

The separator adopts an oil-water separator, which is mainly used to separate water and oil in the gas, reduce the influence of gas humidity on the collection and analysis, and regularly remove the water through the system control solenoid valve.

 

Gas analysis unit

The filtered clean gas is transported to the sensor through the suction pump gas. The detector monitors the gas concentration in real time, and displays the real-time concentration value on the dot matrix LCD screen. The signal is transmitted to the external touch LCD screen. The touch LCD screen also displays the temperature and humidity of the air where the device is located in real time, so that personnel can observe the environment in real time.
