In-place regenerating activating furnace, system and method for saturated active carbon

Abstract

The invention provides an in-place regenerating activating furnace, system and method for saturated active carbon. The in-place regenerating activating furnace, system and method are used for in-place regeneration of saturated active carbon used in a sewage treatment plant. The regenerating activating furnace comprises a furnace body, a driving device, a riding wheel device and a combustion chamber, wherein at least one gas introduction pipe is connected into the furnace body, the outer end of the gas introduction pipe is connected with a gas source, and the gas source is used for supplying combustion-supporting gas; the combustion-supporting gas is introduced into the furnace body through the gas introduction pipe, so that the temperature in the furnace body is increased; energy of the rotary regeneration activating furnace is from natural gas, heavy oil or other oil products. Waste gas produced in the regeneration process is purified by a scrubber tower and then is exhausted through an induced draft fan. With the adoption of the regenerating activating furnace, regeneration of the adsorbed saturated active carbon in the sewage treatment plant can be realized, for indexes after regeneration, the iodine value is higher than or equal to 560 mg / g, methylene blue is higher than or equal to 70 mg / g, and the strength is higher than or equal to 85%; the regeneration yield is not lower than 90% of that of original active carbon. Compared with a traditional method, the method has the advantages that hazardous waste emission reduction, energy conservation and the like are realized, the operation cost of water treatment adopting an active carbon method can be effectively reduced, and good social and environmental benefits are achieved.

Description

technical field [0001] The invention relates to an in-situ regeneration technology of saturated activated carbon, especially a saturated activated carbon in-situ regeneration activation furnace, system and method that can regenerate activated carbon in a sewage treatment plant and return to the sewage treatment process for continued use. Background technique [0002] In 2015, my country's sewage treatment plants began to upgrade and transform, and an important method for improving the quality of sewage is activated carbon adsorption. [0003] In the traditional process, the waste carbon generated after the use of activated carbon in the water treatment plant becomes hazardous waste, which needs to be processed at a high cost by a professional processor. In addition, new carbon needs to be purchased, the overall operating cost is high, and waste hazards are generated. environment, which affects the progress of sewage upgrading work. [0004] The regeneration of activated car...
