Embodiment 1
[0015] This example provides a method for preparing an active adsorbent for volatile organic compound waste gas. The components are calculated by weight: 100 parts of circulating fluidized bed coal-fired boiler fly ash, 5 parts of sulfur, 1 part of disulfur dichloride, Sulfur is heated to 460-480°C to form superheated sulfur vapor, which enters the activation prilling tower at a flow rate of 2-3m / s and is mixed with disulfur dichloride at -20--15°C and the circulating flow sent from the bottom of the tower After the exhaust gas from the fluidized bed waste heat boiler is mixed, it is rapidly cooled to below 90°C to form sulfur glue and disulfide dichloride mist droplets. Glue, disulfur dichloride, and fly ash of circulating fluidized bed coal-fired boiler are fully mixed under the purge of exhaust gas from circulating fluidized bed waste heat boiler and spirally rise in the activated prilling tower. Sulfur gum, disulfur dichloride The mist droplets bond the circulating fluidiz...

[0017] This example provides a method for preparing an active adsorbent for waste gas of volatile organic compounds. The components are calculated by weight: 100 parts of circulating fluidized bed coal-fired boiler fly ash, 10 parts of sulfur, 1 part of disulfur dichloride, Sulfur is heated to 460-480°C to form superheated sulfur vapor, which enters the activation prilling tower at a flow rate of 2-3m / s and is mixed with disulfur dichloride at -20--15°C and the circulating flow sent from the bottom of the tower After the exhaust gas from the fluidized bed waste heat boiler is mixed, it is rapidly cooled to below 90°C to form sulfur glue and disulfide dichloride mist droplets. Glue, disulfur dichloride, and fly ash of circulating fluidized bed coal-fired boiler are fully mixed under the purge of exhaust gas from circulating fluidized bed waste heat boiler and spirally rise in the activated prilling tower.

[0019] This example provides a method for preparing an active adsorbent for waste gas of volatile organic compounds. The components are calculated by weight: 100 parts of circulating fluidized bed coal-fired boiler fly ash, 5 parts of sulfur, 1.5 parts of disulfur dichloride, Sulfur is heated to 460-480°C to form superheated sulfur vapor, which enters the activation prilling tower at a flow rate of 2-3m / s and is mixed with disulfur dichloride at -20--15°C and the circulating flow sent from the bottom of the tower After the exhaust gas from the fluidized bed waste heat boiler is mixed, it is rapidly cooled to below 90°C to form sulfur glue and disulfide dichloride mist droplets.
