Description

Direct combustion return high-efficiency organic waste gas treatment system and method

The present invention relates to a direct combustion recirculation high-efficiency organic waste gas treatment system and method, in particular to a system for recycling the burned gas into the adsorption zone of the adsorption runner without recycling through the chimney.

Therefore, processing equipment for processing volatile organic gas (VOC) will be installed in each plant to avoid volatile organic gas (VOC) is directly discharged into the air and causes air pollution. At present, most of the concentrated gas desorbed by the processing equipment is sent to the incinerator for combustion, and then the burned gas is sent to the chimney for discharge.

However, in recent years, both the central government and local governments have attached great importance to air pollution. Therefore, the air quality standards for suspended particulates (PM ₁₀ ) and fine suspended particulates (PM _2.5 ) have been set in the chimney emission standards. And based on the results of its domestic health impact studies, taking health effects as a priority, the 24-hour value of "fine suspended particles (PM _2.5 )" was set at 35 μg/m ³ and the annual average value was set at 15 μg/m ³ . In addition, the EPA is initially scheduled to reach the national average annual fine particle concentration of 15μg/m ³ in 109 (2020) in the Republic of China. At the same time, it will review its air quality standards for fine particulate matter (PM _2.5 ) phase by phase according to the development of international control trends. In order to achieve the air quality improvement goal set by the WHO (the 24-hour value is set at 25 μg/m ³ and the annual average value is set at 10 μg/m ³ ).
