TK-1600 VOC Online Alarm System
TK-1600 TK-1600 independently developed by Shandong Xinze Instrument 抽取法+紫外灯光源技术（FID） ，主要应用于对各种厂界或固定污染源有机物的实时监测，本系列 TVOC 在线监测系统采用国际先进技术，性能稳定可靠，自动化程度高，检测范围宽，采用微电脑和系统控制软件，实时自动监测分析环境空气中 C2-C12 挥发性有机污染物，可将报警信息传送到监控中心，实现了工作现场的无人值守。 The volatile organic compounds online monitoring system of pollution source adopts advanced extraction method + ultraviolet lamp light source technology (FID) , which is mainly used for real-time monitoring of organics in various plant boundaries or fixed pollution sources. This series of TVOC online monitoring systems use international advanced technology and performance Stable and reliable, high degree of automation, wide detection range, using microcomputer and system control software, real-time automatic monitoring and analysis of C2-C12 volatile organic pollutants in ambient air, and can transmit alarm information to the monitoring center to achieve People on duty. 运行成本. The entire system has a simple structure, a modular design, strong stability, and operating costs.
系统原理 Second, the system principle
When a compound gas or vapor with an ionization potential (IP) that is less than the energy of the UV lamp passes through the ionization chamber, the ultraviolet light source (UV) of the PID will break the compound into positive and negative ions that can be detected (this process is Ionization), the detector measures the ionized gas charge and converts it into a current signal, and then the current is amplified and converted into a concentration value. After being detected, the ions are recombined into the original gas or steam. Advanced non-destructive testing VOC method.
过滤预处理，再通过 PID 变送器测得气体的 VOC 的浓度。 This system uses the extraction method to take out the gas to be measured from the factory boundary or a fixed source. The gas is cooled, dried, filtered and pretreated, and then the VOC concentration of the gas is measured by a PID transmitter .
以及传感器单 元，设计一个防水防尘的必须给机箱来内部安装，预处理系统分为校准、干燥过 滤器和气泵三部分组成。 The entire monitoring system is divided into a pre-processing system, a data acquisition and processing system (RTU), and a sensor unit . A waterproof and dust-proof design must be installed inside the chassis. The pre-processing system is divided into three parts : calibration, drying filter and air pump. .

Five, system characteristics
1. Strengthen the real-time supervision of the safety production of toxic and harmful gas-emitting enterprises by competent authorities, so as to promptly urge the enterprises to make rectifications in a timely manner. For severe cases, punish the enterprises and suspend production for rectification according to relevant regulations to avoid the occurrence of vicious accidents;
2. In the event of exceeding the standard, promptly report the alarm, so that the enterprise and the competent department can make a preliminary plan for the first time, and eliminate the accident in the bud state;
3. In case of serious exceeding the standard, it can provide guidance and suggestions for evacuation of surrounding people in combination with meteorological monitoring data;
4. After the alarm information is transmitted to the monitoring center, it can automatically determine the approximate enterprise location based on the topological map of the location where the existing collection equipment is installed and the enterprises exceeding the standard in the area, so as to remind relevant personnel to alarm the enterprise information and deal with it in a timely manner; using microcomputers And system control software, serial operation fully automatic monitoring and analysis of C2-C12 volatile organic pollutants in ambient air; the system has functions of operation and alarm, interlocking and backflushing, calibration and other functions to ensure long-term operation and self-diagnosis , Reducing maintenance workload and costs.
