Description
Technical Field
The invention relates to the technical field of waste gas treatment, in particular to a waste gas treatment environment-friendly device suitable for small-sized operation places.
Background
The 21 st century will be a new era of development, cleanness, safety, environmental protection and efficient utilization, so the development of a harmful gas treatment device has important practical significance on the problem of air pollution, and has profound influence on the continuous development of human socioeconomic performance. Organic waste gas pollution exists in industrial production, and the organic waste gas has great influence on human health, can harm the liver, the kidney, the brain and the nervous system of a human, even can cause blood problems of the human body, and can cause other serious diseases such as leukemia and the like.
VOC (volatile organic compound) refers to an organic compound having a boiling point of 50 to 260 ℃ at normal pressure and a saturated vapor pressure of more than 133.32Pa at normal temperature, or any organic liquid or solid that can be volatilized at normal temperature and normal pressure. VOCs are complex in order and mainly comprise olefins, alkanes, alcohols, aromatic hydrocarbons, aldehydes, halogenated hydrocarbons, and the like. VOC is also an important precursor for forming haze and an important source of toxic and harmful gases, and has been classified as the greatest air pollution source outside fine particulate matters by the environmental protection department. With the accelerated industrialization progress, the health and environmental problems caused by VOCs are attracting more and more attention, and the treatment of VOCs is also imminent.
The VOC treatment has more measures, and the treatment method comprises source decrement, intermediate control, terminal treatment and the like. At present, the tail end treatment is the main point in China. The end treatment techniques are generally divided into destructive and recycling treatments. Destructive treatments mainly include catalytic combustion and photo-oxidative catalysis. The recycling treatment is generally an activated carbon waste gas treatment adsorption method, and the principle of the activated carbon adsorption method is as follows: an interfacial phenomenon, called adsorption, in which a gas contacts a solid and adheres to the surface of the solid. The adsorbed molecules are returned to the liquid or gas phase, which is called desorption. Adsorption can be divided into physical adsorption and chemical adsorption, depending on the mode of action between the adsorbent and the adsorbate. Physical adsorption is a reversible process, and the action force of the adsorption phenomenon mainly consists of van der Waals force and electric action force between adsorbate molecules and the surface of an adsorbent; chemisorption refers to the process of electron exchange, transfer, or sharing (forming covalent bonds) between the adsorbate and the adsorbent, and is often irreversible. The most essential difference between physical adsorption and chemical adsorption is the nature of adsorption force, and in addition, the two adsorption processes have significant differences in aspects such as selectivity, activation energy, heat of adsorption, the number of adsorption layers, adsorption temperature, adsorption rate and the like, thereby being used as an important basis for judging the adsorption type. The method has the advantages of high removal rate, is a method for removing gas-phase pollutants which is commonly used, but has the defects of high investment and operation cost and secondary pollution, the capacity of the adsorbent is limited, the equipment is large, the post-treatment engineering such as the recovery of the regenerated organic solvent of the adsorbent is complex, the cost is high, solid garbage is generated, and the method is not applied in a large scale at present; the catalytic combustion method is characterized in that a certain catalyst is added during the combustion of waste gas, the ignition point of VOC is reduced, the VOC can be fully combusted, and carbon dioxide and water are finally generated; the principle of treating organic waste gas by the photo-oxygen catalysis method is as follows: the organic waste gas is irradiated by photocatalyst (TiO2) and ultraviolet light to reduce activation energy and is quickly decomposed into dioxygen and water, and the equipment of the photo-oxygen catalysis method consists of components such as an external lamp, a ballast, a photocatalyst (TiO2) net and the like, so that the cost is higher.
