Description
Technical Field
The invention relates to the technical field of activated carbon regeneration, in particular to a desorption regeneration system for sulfur-containing saturated activated carbon.
Background
The active carbon is a product which consumes a large amount of resources in the environmental protection industry, has very good and effective adsorption removal effect on most volatile organic compounds, has stable removal rate before saturation, and is widely used in the market. At present, most of enterprises adopting activated carbon to adsorb and remove VOC have the defects that most of activated carbon is treated as solid waste after being saturated, the activated carbon is not recycled, great resource waste is caused, and other environmental protection problems are caused. Because the manufacturing of the activated carbon can also generate serious environmental protection problems, the regeneration of the saturated activated carbon is particularly important, the secondary pollution can be avoided by recycling, and the cost for purchasing the activated carbon again is reduced. The regeneration process is divided into chemical method, biological regeneration method, wet oxidation method, electrolytic oxidation method, heating regeneration method and the like. The heating regeneration method is the regeneration method with the longest development history and the most extensive application, and the heating regeneration process is to make the adsorbate desorbed at high temperature by utilizing the characteristic that the adsorbate in the adsorption saturated activated carbon can be desorbed from the activated carbon pores at high temperature, thereby opening the originally blocked pores of the activated carbon and recovering the adsorption performance of the activated carbon. After high temperature is applied, molecular vibration energy is increased, the adsorption equilibrium relationship is changed, and adsorbate molecules are separated from the surface of the activated carbon and enter a gas phase. Heating regeneration is a mainstream regeneration method because it can decompose various adsorbates, and thus has versatility and thorough regeneration.
The saturated activated carbon heating regeneration desorption system used in the market at present adopts aerobic low-temperature desorption, the temperature of a carbon layer is generally about 120 ℃, most of the saturated activated carbon heating regeneration desorption system is still at a heating temperature rather than the temperature of the carbon layer in actual use, and the temperature of the carbon layer is not yet 120 ℃, so that the desorption effect is poor, and the activated carbon can be rapidly invalid in a plurality of cycles. And when the existing desorption system desorbs the active carbon containing sulfur, the sulfur is often unqualified to be treated, and the secondary pollution is easily caused when the active carbon is discharged into the air.

(1) desorption and desorption operation: loading the used sulfur-containing saturated activated carbon into a desorption tank 1, closing the desorption tank 1, starting a vacuum pump 21, opening a vacuum valve 22, and carrying out deoxidization treatment on the activated carbon; when the oxygen content in the desorption tank 1 reaches the desorption requirement (the oxygen content is lower than 5%), the vacuum pump 21 and the vacuum valve 22 are closed;
opening a nitrogen valve 33, opening exhaust valves 12 on the first waste gas purification pipeline 7 and the second waste gas purification pipeline 9, starting a heater 31, continuously injecting heated nitrogen into the desorption tank 1, keeping the desorption tank 1 at micro-positive pressure all the time, continuously increasing the temperature of the activated carbon, gasifying sulfur when the temperature is more than or equal to 425 ℃, continuously discharging the gasified sulfur by continuously introduced inert gas nitrogen, entering a high-temperature maintaining pipeline 4, then passing through a condenser 5, cooling and liquefying, and then flowing into a sulfur liquefaction collector 6; the sulfur liquefaction collector 6 is a constant temperature container with the temperature of 120-160 ℃, so when sulfur steam flows into the condenser 5, the temperature is reduced to below 160 ℃ to be liquefied, and then the sulfur steam flows into the sulfur liquefaction collector 6 to be collected; the temperature in the sulfur liquefaction collector 6 is always kept at 160 ℃ below zero, so that the liquefied sulfur can be prevented from being solidified;
