Abstract

The invention provides a humic acid activation method and device. The method comprises steps as follows: a humic acid raw material is mixed with an activating agent, and after water is added and stirring is performed, a mixture is subjected to steam curing in high-temperature and high-pressure saturated steam; correspondingly, the humic acid activation device comprises two reaction kettles which are communicated through a steam distribution header, the steam distribution header is communicated with a steam supply device, steam curing cars are arranged in the reaction kettles, after the humic acid raw material is mixed with the activating agent, water is added and stirring is performed, the mixture is placed on the steam curing cars, and the steam curing cars are put in the corresponding reaction kettles for steam curing reaction. The humic acid is activated under stream pressure, so that the reaction time is shortened, the technology is simple, the energy consumption is low, and the activation effect is good; the two reaction kettles are arranged and can be used for performing the steam curing reaction alternately, continuous production of active humic acid is realized, the production cycle is shortened, and the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of humic acid activation, in particular to a humic acid activation method and device. Background technique [0002] At present, conventional humic acid activation methods include oxidation activation, alkalization activation, etc., all of which undergo a series of process equipment such as activation extraction, solid-liquid separation, evaporation and drying under liquid phase conditions, which have cumbersome processes, high energy consumption, and pollution.
