Online monitoring instrument for exhaust gas and dust

The online monitoring instrument for exhaust gas and dust can monitor volatile organic compounds (VOCs) in fixed pollution sources, factory boundaries, and industrial parks in real time, collect, analyze, and save data in a unified manner, and reflect pollution emissions in real time. The main functions of the VOCs automatic monitoring and alarm system include flue gas pretreatment, online monitoring, data processing, automatic alarm, and data networking.

Application industries of online monitoring instrument for exhaust gas and dust:

Vocs emission monitoring mainly involves industries such as petrochemicals, organic chemicals, pharmaceutical manufacturing, industrial coatings, machinery manufacturing, packaging and printing, electronic production, synthetic leather, coatings and paints, clothing processing, furniture manufacturing, adhesives, footwear, and oil storage and transportation.

Simultaneous emissions have the characteristics of unorganized dispersion and organized fixed pollution source emissions, multiple types of pollutants, large concentration changes, and uncertain emission time. 、

The VOCs automatic monitoring and alarm system can provide real-time contact and provide data on the total amount of VOCs and key monitoring factors in various industries, and is connected to the competent department of the Environmental Protection Bureau in real-time online to achieve real-time monitoring of VOCs total emission reduction and pollution discharge fees.

VOCs installation plan

Fixed source VOCs organized emission installation plan

1. Install VOCs online monitoring and alarm devices at the emission outlet, which can be connected to the enterprise computer through a USB interface to transmit real-time data to the cloud or computer.

2. The data on the computer side retains developable data port protocols, and only requires the Environmental Protection Bureau to provide the platform port. After the protocols are interconnected, they can be connected to the Environmental Protection Bureau platform.

Unorganized VOCs installation plan

1. The VOCs alarm is connected to the RS485 input line of the alarm control host through a tree like wiring method to transmit data to the host.

2. The alarm control host can be plugged in with 3G/4G or connected to the enterprise LAN via Ethernet to transmit real-time data to the cloud.

3. The data on the computer side retains the data port protocol that can be developed. As long as the Environmental Protection Bureau provides the platform port, it can be connected to the Environmental Protection Bureau platform.
