Abstract

The invention discloses a carbon washing tank and a production method of low-ash water-purifying activated carbon. The carbon washing tank includes: a tank body, on which a material inlet, a water inlet, a slurry outlet and a sand outlet are arranged, and the sand outlet is located at the side of the slurry outlet. Below; a stirring device, which is arranged in the tank body. The production method of activated carbon for water purification with low ash content comprises: preheating the crushed carbonized material, activating with water vapor, cooling, crushing, and then elutriating through a charcoal washing tank; desanding and After desliming, add it to the modified container, add water to submerge the material, then add acid or alkaline modifier, stir to make the pH of the water 6.5-7.5; rinse and dehydrate the modified material in turn and dry. The charcoal washing tank provided by the invention can quickly clean the activated carbon and reduce the impurity and ash content of the activated carbon. The activated carbon produced by the method of the invention has low ash content, well-developed micropores, high iodine adsorption value, and improves the adsorption capacity of the activated carbon.

Description

technical field [0001] The invention relates to the technical field of activated carbon production. More specifically, the present invention relates to a carbon washing tank and a method for producing activated carbon for water purification with low ash content. Background technique [0002] As the most effective solution to ensure drinking water safety, water purifiers have been developing rapidly in my country in recent years. According to relevant data, from January to May 2017, the retail sales of the water purification market exceeded 4.8 billion yuan, and the retail volume exceeded 3.1 million units, a year-on-year increase of more than 10%. However, as the key material of water purifiers, activated carbon has been plagued by water purifier enterprises in my country for its quality, mainly manifested in high ash content, high impurities, less effective micropores, stained hands, poor taste, and poor cleanliness. The root cause of these problems is the high ash conten...
