A method of using a dedicated activated prilling tower for the preparation of a volatile organic compound waste gas active adsorbent

Abstract

The invention relates to the technical field of controlling volatile organic compound waste gases, in particular to a use method of an activation granulation tower special for preparing a volatile organic compound waste gas active adsorbent. The use method is characterized in that a tail gas discharged from a circulating fluidized bed waste heat boiler rises spirally in an activation granulation tower to achieve technological processes of mixing, cooling, activation, granulation and separation with overheated sulfuric steam, circulating fluidized bed coal-fired boiler fly ashes and disulfur dichloride fog drops, thereby completing an entire technical process of activation granulation of the adsorbent in the tower, and enabling batch continuous production to become possible.

Description

technical field [0001] The invention relates to the technical field of volatile organic compound waste gas treatment, in particular to a method for using an activated granulation tower dedicated to the preparation of volatile organic compound waste gas active adsorbents. Background technique [0002] Gaseous pollutants emitted by industry are the main source of atmospheric environmental pollutants, among which volatile organic compound waste gas (VOCs) is a gaseous pollutant that is seriously harmful to the environment, and it is also an occupational hazard that affects the health of operators in the workplace It is widely derived from chemical industries such as paints, coatings, coatings, lubricants, and rubber. Due to its huge destructive effect on the human body and the natural environment, the country has issued relevant laws and regulations to strictly control its governance and emissions. At present, the commonly used treatment methods of organic waste gas treatment ...

Problems solved by technology

[0003] Existing technology example 1 uses the process of sending zeolite and activator (catalyst) copper oxide and oxyferric chloride into a muffle furnace for calcination to prepare an organic waste gas adsorbent. Usually, the muffle furnace is used for experimental analysis, and the method description is also The experimental process, that is to say, the technology is still a long way from industrialization; the existing technology example 2 uses activated carbon as raw material, which is modified and activated. It is a calcination furnace with many process steps, which cannot be continuously produced, and the labor intensity of the operators is relatively high, and environmental pollutants and occupational disease hazard factors are likely to be generated during the process of production; the third example of the prior art should be a technical solution closer to the present invention , the working principle is also relatively similar, because the technical fields they belong to are different, the technical solutions applied are different, and the process devices for their preparation are also different
