Abstract

The invention discloses a carbon washing groove and a production method of low-ash-content water purification activated carbon. The carbon washing groove comprises a groove body and a stirring device,wherein the groove body is provided with a feeding opening, a water inlet, a slurry outlet and a sand grain outlet; the sand grain outlet is located below the slurry outlet; and the stirring device is arranged in the groove body. The production method of the low-ash-content water purification activated carbon comprises the following steps: pre-heating a crushed carbonized material, carrying out water steam activation and cooling; then crushing; washing through the carbon washing groove; after carrying out sand removal and mud removal on a washed material, adding the material into a modification container; then adding water to immerse the material; then adding an acidic or alkaline modifying agent and stirring to enable the pH (Potential of Hydrogen) value of the water to be 6.5 to 7.5; and rinsing, dehydrating and drying the modified material in sequence. The carbon washing groove provided by the invention can be used for rapidly washing the activated carbon to reduce the impurity andash content of the activated carbon. The activated carbon produced by the method disclosed by the invention has low ash content, developed micro-pores and high iodine absorption value and the adsorption capability of the activated carbon is improved.

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...
