Problems solved by technology

This kind of production process, one is high energy consumption, will cause a lot of energy waste, the other is serious pollution to the environment and groundwater
In order to save energy, some enterprises adopt the method of drying in the sun. Although this drying method reduces energy consumption, it still cannot solve the problem of environmental and groundwater pollution.

Embodiment 1

[0008] Embodiment 1: take 1 ton of weathered coal, and sample from it for analysis and test, calculate its humic acid content to be 50%; put the weathered coal into the semi-closed reaction tower, put into 150 kilograms of sodium hydroxide simultaneously, stir evenly, and feed steam Heating, and controlling the temperature at 100 degrees Celsius for 24 hours to make it fully react, and then keeping the temperature at 100 degrees Celsius for 8 hours to obtain the sodium humate product of the present invention.

Embodiment 2

[0009] Embodiment 2: take 1 ton of weathered coal, and sample from it for analysis and test, and calculate its humic acid content to be 45%; put the weathered coal into the semi-closed reaction tower, put into 50 kilograms of potassium hydroxide simultaneously, stir evenly, and feed steam Heating, and controlling the temperature at 85 degrees Celsius for 36 hours, to make it fully react, and then keeping the temperature at 60 degrees Celsius for 10 hours to obtain the potassium humate product of the present invention.

Embodiment 3

[0010] Embodiment 3: get 1 ton of lignite, and sample from it for analysis and test, calculate its humic acid content to be 55%; drop lignite into semi-closed reaction tower, drop into 200 kilograms of sodium hydroxide simultaneously, stir evenly, pass into steam for heating, The temperature is controlled at 120 degrees Celsius for 12 hours to make it fully react, and then it is kept at 120 degrees Celsius and aged for 5 hours to obtain the sodium humate product of the present invention.

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...
