Honeycomb coal made from fermented cow dung and preparation method thereof

Abstract

The invention discloses a honeycomb briquette prepared by using fermented cow dung and a preparation method thereof. The honeycomb briquette comprises 20wt%-50wt% of maturely fermented cow dung and 50wt%-80wt% of pulverized coal. The preparation method of the honeycomb briquette comprises the following steps of (1) adding a certain amount of fermentative bacteria and rice hull powder to the cow dung so as to ferment the cow dung into the maturely fermented cow dung; and (2) fixing and forming, namely mixing the maturely fermented cow dung with the pulverized coal, crushing, stirring and mixing uniformly, selectively adding water during uniform mixing, and carrying out compression molding. The brand-new honeycomb briquette prepared by mixing the fermented cow dung and the pulverized coal, provided by the invention, is odorless and has high acceptability; smashed grasses or straws do not need to be additionally added to the honeycomb briquette, so that the cost is saved, and the honeycomb briquette is easy to form; and the preparation time of the honeycomb briquette is short, and the preparation process is simple, so that the honeycomb briquette is easy to popularize. The preparation method has the advantages that (1) the pollution problem of cattle farms can be greatly reduced; (2) the shortage of fuels can be solved; and (3) the utilization model of energy sources is explored.

Description

technical field [0001] The invention relates to a briquette, in particular to a briquette made from fermented cow dung and a preparation method of the briquette. Background technique [0002] my country is the world's largest producer of animal husbandry and one of the countries with the largest number of cattle. With the increasing intensification of animal husbandry production, a large amount of excrement and waste generated in the breeding production process has surged, causing environmental pollution. At the same time, my country is a country with very tight coal resources, and the development of renewable energy has always been a very valuable topic and direction of efforts. It is estimated that the total amount of livestock and poultry manure resources in my country is about 26×10t, which is equivalent to 1.12×10t of standard coal. [0003] In recent years, in the face of the environmental pollution caused by cow dung, people have tried to make fertilizer and coal fr...

Problems solved by technology

At present, the research on making coal from cow dung is still at the stage of directly using cow dung to mix coal machinery. On the one hand, due to the high water content of cow dung, the coal produced by this method often needs to add additional grass or straw etc. The coal produced in this way has a low combustion value and is not easy to form, or the cow dung needs to be slowly and naturally air-dried, and due to the high water content of fresh cow dung, it takes a long time to air-dry, and the air-drying process is easy to breed mosquitoes and flies, etc., polluting the environment. On the other hand, untreated cow dung has an unbearable odor, and the coal produced and the coal burning process also have an unpleasant odor, which is not easy to be accepted by users
