Description
技术领域 technical field
本实用新型属于大气治理设备领域，具体涉及一种挥发性有机气体的吸收净化装置。 The utility model belongs to the field of atmospheric treatment equipment, in particular to an absorption and purification device for volatile organic gases.
背景技术 Background technique
挥发性有机气体（VOCs）是常见的大气污染物。VOCs来源广泛，工业源主要来源于石化、制药、印刷、喷漆、钢铁等重点行业。该类有机物大多具有毒性，且挥发到大气中不仅会危害人体健康，部分有机废气还会形成光化学烟雾，从而导致雾霾天气，氟氯烃(CFC)类化合物还具有破坏臭氧层的作用。因此，对VOCs控制方法的研究一直是国内外研究热点问题之一。 Volatile organic gases (VOCs) are common air pollutants. VOCs have a wide range of sources, and industrial sources mainly come from key industries such as petrochemicals, pharmaceuticals, printing, painting, and steel. Most of these organic substances are toxic, and volatilization into the atmosphere will not only endanger human health, but some organic waste gases will also form photochemical smog, resulting in haze weather, and chlorofluorocarbon (CFC) compounds also have the effect of destroying the ozone layer. Therefore, the research on VOCs control methods has always been one of the hot research issues at home and abroad.
目前VOCs废气的治理技术主要有：吸收法、氧化法、吸附法、生物法、膜处理法等，其中吸收法净化气态污染物，是利用适当的吸收剂，从废气中选择性地去除气态污染物以消除污染，针对VOCs气体而言，主要利用VOCs溶解度的不同来实现分离净化。该方法设备简单、一次性投资费用低，广泛应用于可溶性气态污染控制中。填料吸收塔是以塔内的填料作为气液两相间接触构件的传质设备。填料塔的设计直接影响到整个填料塔的操作运行和填料性能的发挥。填料的性质、气液接触面积、传质效率等因素一直是人们的研究方向。 At present, the treatment technologies of VOCs waste gas mainly include: absorption method, oxidation method, adsorption method, biological method, membrane treatment method, etc. Among them, the absorption method to purify gaseous pollutants is to use appropriate absorbents to selectively remove gaseous pollution from waste gas In order to eliminate pollution, for VOCs gas, the difference in solubility of VOCs is mainly used to achieve separation and purification. The method has simple equipment and low one-time investment cost, and is widely used in the control of soluble gaseous pollution. The packed absorption tower is a mass transfer device in which the packing in the tower is used as a contact member between the gas and liquid phases. The design of the packed tower directly affects the operation of the entire packed tower and the performance of the packing. The nature of packing, gas-liquid contact area, mass transfer efficiency and other factors have always been the research direction of people.
紫外光与氧化剂联用的高级氧化技术，无论是UV/NaClO、UV/Fenton、UV/H2O2等，均能产生协同作用，其本质都是生成氧化性更强的羟基自由基。因此，将传统的填料吸收塔与先进的光氧化技术相联合，不仅可有效改善填料塔的传质效率，而且增强了化学吸收氧化剂对VOCs的降解性能，具有广阔的应用前景。 The advanced oxidation technology combined with ultraviolet light and oxidant, whether it is UV/NaClO, UV/Fenton, UV/ H2O2 , etc., can produce synergistic effects, and its essence is to generate more oxidative hydroxyl radicals. Therefore, combining the traditional packed absorption tower with advanced photooxidation technology can not only effectively improve the mass transfer efficiency of the packed tower, but also enhance the degradation performance of chemical absorption oxidants on VOCs, which has broad application prospects.
