Description

Microwave regeneration moving layer furnace of active carbon filter layer in industrial purification equipment

Technical Field

Background

The activated carbon adsorption technology is widely applied to the technical fields of urban water supply treatment, sewage and wastewater treatment, food processing, chemical production, wet metallurgy and the like. Because of the excellent adsorption effect on organic matters, heavy metals and other pollutants in a water system, the consumption and consumption of activated carbon every year are huge. Because the activated carbon is expensive, the granular activated carbon needs to be regenerated after being adsorbed and saturated so as to recover the adsorption capacity.

In the conventional regeneration method, such as a thermal regeneration method, the activated carbon is taken out, dehydrated, dried and heated to over 600 ℃ so that the adsorbed organic matters are completely decomposed into inorganic matters such as CO2, N2, H2O and the like, and the activated carbon is regenerated. The disadvantages of the thermal regeneration method are that the regeneration process is complex, the time consumption is long, the energy consumption is high, and the carbon damage rate is high. The chemical regeneration is to soak the chemical agent to dissolve the adsorbed organic matter into the liquid medicine to achieve the purpose of analysis, but has the defects that the price of the agent is high, only part of specific organic matter can be analyzed in a targeted manner, and the application in a large range cannot be realized. The biological regeneration method is to propagate great amount of microbes on the active carbon and decompose the adsorbed organic matter with the microbes to maintain the adsorption capacity of the active carbon. The greatest defect of the biological regeneration method is that the method can only be applied to micro-polluted water with inlet water organic matter below 10mg/L to maintain dynamic balance of adsorption and biological regeneration, and the organic matter content of most of the using occasions of the active carbon is far higher than 10mg/L, so that the method is not suitable for biological regeneration. The use of activated carbon is severely limited due to problems with activated carbon regeneration technology.
