Specification for high efficiency waste gas filter tank for treating organic waste gas in Wuxi printing plant
Summary
Activated carbon adsorption tower also known as active carbon filter, activated carbon filter, activated carbon adsorption tank. | activated carbon filter (tower) is a waste gas filtering adsorption odor and I developed the production of environmental protection equipment, activated carbon adsorption tower is available, PP stainless steel and carbon steel plate and other materials. Adsorption of activated carbon adsorption tower with high efficiency, wide application, convenient maintenance, can also handle a variety of mixed gases etc., formaldehyde, benzene, TVOC and other harmful gases and disinfection deodorizing effects with the removal of activated carbon, activated carbon adsorption tower is now widely used in electronic components (battery) battery production, production, processing and pickling laboratory ventilation, metallurgy, chemical, pharmaceutical, food, brewing, coating and other organic waste, including lacquering treatment purification is the most widely used.
Activated carbon adsorption principle explanation
The adsorption can be divided into physical adsorption and chemical adsorption; because between adsorbent and adsorbate molecular electrostatic attraction causes or caused by physical adsorption, when the molecular attraction between solid and gas is larger than the gravitational force between gas molecules, even if the gas pressure is lower than the operating temperature and the corresponding saturation vapor pressure, gas molecules will condense on the solid surface, physical adsorption is an exothermic process. Also known as chemical adsorption activity is due to adsorption, chemical reaction force of the adsorbent surface and adsorbate molecules lead to chemical adsorption, it involves a combination of RE, and the chemical bonds in the molecule damage so the heat of adsorption process of chemical adsorption is physical adsorption process. In the process of adsorption, there is no strict boundary between physical adsorption and chemical adsorption, and the physical adsorption of the same substance at lower temperature may occur. Activated carbon adsorption is mainly physical adsorption, but due to the presence of surfactants, but also a certain chemical adsorption.
Activated carbon is a porous material containing carbon, it has a highly developed pore structure, porous structure of activated carbon to provide a large surface area, and gas (impurities) full contact, thus giving the adsorption properties of activated carbon are endemic, make it very easy to achieve the collection of impurity absorption objective. Just like magnetic force, all molecules have mutual attraction. Because of this, a large number of molecules on the pore wall of the activated carbon can produce a strong gravitational force, so as to achieve the purpose of attracting harmful impurities to the aperture.
