Method for producing sodium humate (potassium humate) with drying method

Abstract

The invention relates to a method for producing sodium humate (potassium humate) with a drying method. Firstly, samples of weathered coal or wood coal are analyzed and assayed; the content of humic acid of the samples is calculated; the weathered coal or the wood coal are added into a semiclosed reaction tower; sodium hydroxide (potassium hydroxide) which accounts for 5-20 percent of the weight of the weathered coal and (or) wood coal is added to the semiclosed reaction tower according to the content of the humic acid in the weathered coal or the wood coal and is uniformly mixed with the weathered coal or the wood coal; steam is led inside to heat the weathered coal or the wood coal and the sodium hydroxide (potassium hydroxide) so as to cause the same to react thoroughly; and finally, the product is carried out heat preservation and aged. The invention used for producing the sodium humate (potassium humate) has the advantages of simple process, no black environmental pollution and groundwater pollution and low energy consumption, thereby being beneficial to energy conservation and reducing the production cost.

Description

Technical field: [0001] The invention belongs to the technical scope of sodium humate (potassium) production, and relates to a production method of sodium humate (potassium), particularly a dry production method. Background technique: [0002] In the prior art, the production method of sodium humate (potassium) usually adopts the production technology of reaction extraction, concentration and drying. This production process, firstly, consumes high energy, which will cause a lot of energy waste, and secondly, causes serious pollution to the environment and groundwater. In order to save energy, some companies use the method of drying in the sun. Although this drying method reduces energy consumption, it still cannot solve the problem of pollution to the environment and groundwater. Invention content: [0003] The purpose of this invention is to provide a kind of sodium humate (potassium) dry production method, in order to effectively solve and overcome the above-mentioned d...
