Process device for preparing hypersorber for volatile organic compound waste gas

Abstract

The invention relates to the technical field of governance of volatile organic compound waste gas and in particular relates to a process device for preparing a hypersorber for the volatile organic compound waste gas. The process device is characterized by comprising an active granulation tower, a supporting frame, a circulating fluidized bed coal-fired boiler fly ash screw feeder, a disulfur dichloride storing tank assembly and a sulfur evaporator. The content of oxygen in tail gases exhausted by a circulating fluidized bed waste heat boiler is extremely-low, so that the probability of burning explosion of sulfur in a low-oxygen environment is extremely-low, and further safe production is facilitated; meanwhile, the hypersorber serving as a process cooling medium of sulfur adhesive is very ideal, and realizes the functions of the sulfur adhesive serving as an adhesive and an adsorbent; the tail gas exhausted by the circulating fluidized bed waste heat boiler spirally ascends in the active granulation tower, wraps the sulfur adhesive and disulfur dichloride vaporific droplets, and activates fly ash of a circulating fluidized bed coal-fired boiler to form continuously-growing particles for sufficient mass transfer and heat transfer, thereby finishing the whole process flow of activating and granulating an adsorbent in the tower, and enabling industrialized production to become possible.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment of volatile organic compounds, in particular to a process device for preparing active adsorbents for waste gas of volatile organic compounds. 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 technology include combustion method, c...

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
