Description

Direct combustion reflux high efficiency organic waste gas treatment system

The present invention relates to a direct combustion reflux high-efficiency organic waste gas treatment system, in particular to a recycling zone for the combustion of gas into the adsorption zone of the adsorption wheel, and does not pass through the chimney for discharge, so that the organic waste gas The processing efficiency can be improved, and it is applicable to organic waste gas treatment systems or the like in the semiconductor industry, the photovoltaic industry or the chemical related industries.

According to the current production process in the semiconductor industry or the optoelectronic industry, volatile organic gases (VOC) are produced. Therefore, processing equipment for treating volatile organic gases (VOC) is installed in each plant to avoid volatile organic gases. (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 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, and therefore have set air quality standards for suspended particulates (PM ₁₀ ) and fine aerosols (PM _2.5 ) on chimney emission standards. Based on the results of the domestic health impact study, the health impact was prioritized. The 24-hour value of "fine aerosol (PM _2.5 )" was set at 35 μg/m ³ and the annual average was set at 15 μg/m ³ . And the EPA has initially set a target of 15μg/m ³ of annual national average fine aerosol concentration in the Republic of China in 109 (2020), and will review its fine aerosol (PM _2.5 ) air quality standards on a phase-by-period basis in accordance with international regulatory trends. The air quality guideline value (25-hour value is set to 25 μg/m ³ and annual average is set to 10 μg/m ³ ) is the goal of achieving air quality improvement.
