Abstract

The invention discloses a device for extracting medical grade fulvic acid from decomposed coal. The device comprises a pure water preparation unit, a mixed extraction unit, a fulvic acid refining unitand a separation regeneration unit. An extracting technology for extracting medical grade fulvic acid from the decomposed coal disclosed by the invention comprises the following steps: preparing purewater, performing mixed extraction, refining fulvic acid, separating and regenerating and obtaining high-purity medical grade fulvic acid. The device for extracting the medical grade fulvic acid fromthe decomposed coal disclosed by the invention has the advantages of simple structure, convenience in operation and suitability for large scale production. According to the device disclosed by the invention, pure water is utilized as an extracting agent, and the pure water is not prone to volatilizing, has no toxin and is easier to recycle; an extracting technology has the characteristics of simpleness in operation, strong reliability, energy conservation and environmental friendliness; compound ion exchange resin is utilized, so that cost is low, fulvic acid extracting time is short, and anextracting rate is high; the extracted fulvic acid has the advantages of high purity, strong physiological activity and stable performance.

Description

technical field [0001] The invention belongs to the technical field of fulvic acid extraction, and in particular relates to a device for extracting medical-grade fulvic acid from weathered coal and an extraction process thereof. Background technique [0002] Fulvic acid is one of the components of soil humus. It is a biologically active low-molecular-weight yellow substance. It is the ultimate decomposed form of all active organisms. It has a microstructure and is highly soluble. It is suitable for different acid-base components and can be used in all Decomposes at pH. Fulvic acid is a highly diverse and complex combination. It has an extremely complex molecular structure. It is formed by the combination of microbial secretions and phytochemicals. It is continuously structured and recombined during the humification (decomposition) process. With unusual properties and abilities, it can change and transform molecular combinations, including almost all organic and inorganic su...

Problems solved by technology

The method used in this paper is only to study the influence of various experimental factors on the process, without modifying various processes, and each process is a small laboratory test, and there is no large-scale device

[0004] In 2012, Wen Pengli, Shanxi University's master's degree thesis "Research on the Key Technology of Extracting Fulvic Acid from Weathered Coal", proposed a new extraction method of fulvic acid - sulfuric acid ethanol method, which was extracted under the most experimental conditions. The extraction rate of fulvic acid from weathered coal in Inner Mongolia is 32.28%. This method has the advantage of low energy consumption, but it is limited to laboratory tests, and the environmental and economic benefits of this method have not been evaluated.

The method is complicated to operate, the process cost is high, and it is not suitable for industrial production
