Production technology of environmental-friendly regeneration activated carbon

Abstract

The invention discloses a production technology of environmental-friendly regeneration activated carbon. The production technology comprises the following steps: (1) performing storage; (2) performingnegative pressure treatment; (3) performing fuel preparation; (4) performing calcination and combustion: moving a combustion jar fully loaded with raw materials in the step (2) into a numerical control high-temperature smoldering furnace, and performing calcination treatment, wherein airtight doors are formed in two end of the numerical control high-temperature smoldering furnace, when the combustion jar is moved in or out of the numerical control high-temperature smoldering furnace, a furnace door is automatically and tightly closed, and the whole calcination stage comprises a drying stage,a carbonisation stage, an activation stage and a cooling stage; and (5) performing after-treatment and packaging. According to the production technology disclosed by the invention, through massive experiment, the optimal production technology steps of the environmental-friendly regeneration activated carbon are screened out, the adsorbability of the regeneration activated carbon produced through the production technology can reach 105%-120% that of original activated carbon, the intensity is strengthened based on the original intensity, and the regeneration rate can be maintained to be 95% orabove.

Description

technical field [0001] The invention relates to an environment-friendly regenerated activated carbon production process, which belongs to the technical field of fine chemicals. Background technique [0002] Activated carbon is a kind of adsorption material with well-developed pore structure, large specific surface area, non-toxic and tasteless, and is currently widely used in the advanced treatment of urban sewage, industrial wastewater and purification of polluted water sources. However, due to the high price of activated carbon and the shortage of production resources, if the saturated activated carbon is discarded, it will inevitably cause waste of resources and cause secondary pollution to the environment. Therefore, from the perspective of economy and environmental protection, the regeneration of activated carbon has a Significance. At present, the technologies for regeneration of activated carbon mainly include: chemical agent regeneration method, thermal regeneration...

Problems solved by technology

[0003] At present, the production process of regenerated activated carbon is to artificially pack the waste activated carbon into clay pots, move it to an earthen kiln to heat and regenerate, use scattered wood to heat up from 30°C to 900°C, and after constant temperature for 18 hours, directly spray water to cool down to 30°C. After ℃, manually move out of the machine for screening, packaging and warehousing. The traditional regeneration activated carbon production process is seriously polluted, labor-intensive, high energy consumption, low quality and unstable
