Description

Reflux heat recovery high-efficiency organic waste gas treatment system and method

The present invention relates to a high-efficiency organic waste gas treatment system and method for reflux heat recovery, and particularly refers to a method for recycling the combusted gas into the adsorption zone of the adsorption runner without passing through the chimney for discharge. The efficiency of organic waste gas treatment can be improved, and it is suitable for organic waste gas treatment systems or similar equipment in the semiconductor industry, photoelectric industry or chemical-related industries.

According to the current manufacturing process in the semiconductor industry or the optoelectronic industry, volatile organic gases (VOC) are generated. Therefore, processing equipment for processing volatile organic gases (VOC) will be installed in each plant to avoid volatile organic gases. (VOC) is directly discharged into the air to cause air pollution. At present, most of the concentrated gas desorbed by the processing equipment is transported to the incinerator for combustion, and then the combusted gas is transported to the chimney for discharge.

However, in recent years, both the central government and local governments have attached great importance to air pollution. Therefore, air quality standards for suspended particulates (PM ₁₀ ) and fine suspended particulates (PM _2.5 ) have been set in the emission standards of chimneys. And based on the results of its domestic health impact research, with health impact as the priority consideration, the 24-hour value of "fine suspended particulates (PM _2.5 )" is set at 35μg/m ³ and the annual average value is set at 15μg/m ³ . In addition, the Environmental Protection Agency preliminarily plans to achieve the national average concentration of fine suspended particulates of 15μg/m ³ in 109 (2020). At the same time, it will review its fine suspended particulates (PM _2.5 ) air quality standards in accordance with the development of international control trends , And to achieve the air quality guidelines proposed by the WHO (the 24-hour value is set at 25μg/m ³ and the annual average is set at 10μg/m ³ ) as the air quality improvement target.

Therefore, in view of the above-mentioned deficiencies, the present inventors expect to propose a high-efficiency organic waste gas treatment system and method for recirculation heat recovery that can improve the efficiency of organic waste gas treatment so that users can easily operate and assemble. , In order to provide user convenience, is the motive of the inventor's research and development.

The main purpose of the present invention is to provide a high-efficiency organic waste gas treatment system and method for recirculation heat recovery. The exhaust energy of the incinerator is mainly used for heat exchange through a cooler, and the exhaust gas is cooled and then sent to the waste gas. The gas pipeline allows the combusted gas to enter the adsorption zone of the adsorption runner for recycling without passing through the chimney for discharge, so that the chimney emissions can be reduced, and the treatment efficiency of organic waste gas can be improved. Increase the overall practicality.

Another object of the present invention is to provide a high-efficiency organic waste gas treatment system and method for recirculation heat recovery. A high-temperature desorption zone is added through the adsorption rotor to enable the on-line operation (ON LINE). The residual high boiling point organics (VOC) are removed, so that the adsorption rotor can restore its adsorption capacity, and increase the treatment efficiency of volatile organic waste gas, and achieve the effect of reducing pollutant emissions, thereby increasing the overall usability.
