VOCs are abbreviations for volatile organic compounds. According to the WHO, volatile organic compounds (VOCs) refer to organic compounds with a boiling point of 50 ° C to 260 ° C at room temperature. VOC according to their chemical structure, can be further divided into: alkanes, aromatic hydrocarbons, esters, aldehydes and others. There are currently more than 300 identified. The most common benzene, toluene, xylene, styrene, trichlorethylene, chloroform, trichloroethane, diisocyanate (TDI), such as cyanuric chloride. According to the statistics, the VOCs emissions of our country have been increasing year by year. The emissions of industrial VOCs have increased greatly. In 2012, the emission of VOCs is 20,887,000 tons. It is estimated that the emissions of industrial VOCs will reach 21,472,200 tons and 36,608,500 tons in 2030 . VOCs emissions become larger what exactly would cause harm? Want to use facts to convince everyone! Beginning on May 16 this year, Beijing air pollution increased to the bottom is VOCs, volatile organic compounds will not only generate ozone, but also PM2.5 "Precursor." Some experts said uncontrolled emission of VOCs, the impact of ozone pollution control, if the ozone problem is not solved, to some extent, will exacerbate PM2.5 pollution. Therefore, in the "13th Five-Year Plan", the state government put VOCs in the overall control indicators. In the meantime, Beijing, Tianjin, Shanghai, Hebei, Liaoning and other 10 provinces and cities have issued VOCs emission charges. Relevant enterprises have also introduced VOCs for volatile organic compounds (VOCs) on-line monitoring system and exhaust gas treatment system. The full on-line dual-trap atmospheric preconcentration TOFmsVOCs monitoring system reported by ACC Tech 2016 is called the representative product of on-line monitoring of atmospheric VOCs and also received "2015 New Products of Scientific Instruments Industry". The product has three major technological innovations: no blind spots ----- 100% data collection, a comprehensive reflection of the current volatile organic compounds in the air (unique technology); Fast ----- the fastest data resolution up to 3 minutes (depending on system configuration and application); Universal ----- Adapt to most of the volatile organic compounds in a single analysis. Currently there are several methods for the mainstream of exhaust gas treatment: combustion method, specifically, direct combustion (RTO), catalytic oxidation combustion (RCO); condensation, liquid absorption, activated carbon adsorption, and biofilter Other methods. Different industries and exhaust emissions, the applicable exhaust gas treatment technology and process combination is different. Heraeus, Germany for the introduction of some concentrations are not high, but also mixed with difficult to handle the smell, the gas more types of applications, the introduction of UV catalytic oxidation technology. UV catalytic oxidation method is more economical, much cheaper than the combustion method; treatment effect of stability, consistency better than the adsorption method, running costs and maintenance costs lower. Thanks to the modular design concept, Heraeus's UV exhaust gas treatment system can be flexibly used with different technologies to greatly expand the application fields and conditions of the exhaust gas treatment, so as to obtain the maximum benefit with minimal investment. Data show that the output value of the VOCs treatment and monitoring market will reach 135 billion yuan by 2015, and it is estimated that the market scale of VOCs will exceed 800 billion yuan at the end of the "12th Five-Year Plan" period. However, during the "13th Five-Year Plan", the market scale of VOCs will exceed 140 billion yuan. In recent years, cities have set up emission charges for VOCs one after another, but the premise of this system is that the government has specific, quantifiable and sustainable data sources for VOCs in ambient air and pollution sources. Therefore, VOCs are the first beneficiaries of governance Monitoring industry. VOCs governance is a long-term systematic process, to be prepared to fight protracted war. The next step also requires companies to introduce more quality products and monitoring systems to gradually improve the status quo.
