CN102504277A - Innovative process technology for producing humate with weathered coal - Google Patents

Abstract

The invention discloses an innovative process technology for producing humate with weathered coal. In the conventional general process technical equipment for producing humic acid, a liquefaction heating wet method is adopted for producing, a process is complex, intermittent production is performed, the work period is long, the efficiency is low, the cost is high, and 3-5 tons of coal which is 400-800 yuan per ton in minimum is needed for drying water which is five times that of raw materials during production of 1 ton of humic acid. In the innovative process technology, a dry method is adopted for producing, so that the process is simple, operation is easy, the continuous production efficiency is high, and the comprehensive cost is reduced by over 500 yuan per ton. The innovative process technology has small investment and high efficiency, and is economic and applicable.

Description

Weathered coal is produced the innovative technology technology of humate

Technical field

The present invention's innovation relates to a kind of humate new process of production technology, particularly a kind of economic and practical novel method with weathered coal production humic acids.

Background technology

Humic acids is the natural organic high-molecular compound, is present in weathered coal, peat, the peat composed of rotten mosses; Brown coal are in the peat, because of it is that a kind of industrial chemicals of multi-functional cheapness is widely used in industrial or agricultural, forestry and animal husbandry; Many industries such as fertilizer medicine. and its main production raw material is the low heat value weathered coal, peat, brown coal etc., abundant raw material; Price is low, and product performance are stable, storage transportation easy to use.

Traditional production extraction process is complicated, and wet method liquid decomposes extraction energy consumption height, and man-hour is long, and efficient is low, and cost is high.

The present invention is directed to existing wet extraction process technical equipment existing problems, adopt almost the dry production technology is extracted the weathering coal dust in high-pressure molding heat and reflect heat. and it is simple to have technology, practical; Free from environmental pollution again, low power consuming, casual labourer's preface; Quickness and high efficiency reduces production costs greatly, enhances productivity; But and industrialization, the mass-producing continuous production.

Its technical process is following:

1. weathered coal is ground into 0.5-1.5 millimeter powder through cyclonic separation selection by winnowing decon;

With the weathered coal of selection by winnowing and the natural alkali lye that contains concentration 10-30% or acid solution by solid-to-liquid ratio 1: 0.5-0.8 spreading or ball milling, puddle evenly;

3. with above batching high-pressure molding, generate humate to push the strong physical and chemical reaction of heat and reaction heat;

4. but natural air drying dries or adds oven dry less.

Production technology of the present invention is brief more quick than technology with traditional wet liquefaction; Enhance productivity greatly and economic benefit non-environmental-pollution again. like one ton of humate of wet production; Need to remove the moisture of 5 times of raw materials, use coal 3-5 ton, get 400-800 unit cost at least. and with high-pressure molding particle of the present invention; But seasoning or dry airing a little and promptly do, it is per ton more than at least 500 yuan man-hour that only this saves coal consumption.

This patented invention is compared with conventional art, and production efficiency and remarkable in economical benefits are easy to utilize.

Claims (2)

1. dry technology for production is technological;

2. the natural alkali lye of weathered coal and concentration 10-30% or acid solution 1: 0.5-0.8 fill a prescription.
