Preparation method for pig manure charcoal

Abstract

The invention discloses a preparation method for pig manure charcoal. The method comprises the following steps: 1) uniformly mixing pig manure raw material with calcium hydroxide, thereby acquiring a pig manure mixture; 2) drying the pig manure mixture; 3) performing stick-making and slicing treatment on the dried pig manure mixture; 4) performing carbonizing treatment on the pig manure mixture after the stick-making and slicing treatment, thereby preparing the pig manure charcoal. The preparation method is short in production period, less in additive and low in cost, is capable of reducing the emission of sulfur dioxide in a combustion process of the pig manure charcoal and is capable of reducing the environmental pollution; the prepared end product of the pig manure charcoal is subjected to carbonizing treatment, so that the pig manure material cannot be seen and the discomfort of the user in use can be avoided; the pig manure charcoal can be conveniently popularized and used; the problem of secondary pollution is avoided; the pig manure charcoal has excellent epidemic prevention effect; the pig manure charcoal subjected to carbonizing treatment is clean and hygienic, is difficult to mildew, can be conveyed for a long distance and can be conveniently conveyed and used.

Description

technical field [0001] The invention relates to a method for preparing pig manure biochar. Background technique [0002] Large-scale pig farms have become the trend of modern pig farming, but the pollution of the surrounding environment due to high-density farming load cannot be ignored. Although many pig farms have tried breeding pollution treatment measures, most of the treatment objects are concentrated in sewage. Standard treatment, pig manure separated from solid and liquid is simply transported as waste or randomly piled up, breeding mosquitoes, and causing secondary pollution to the surrounding environment. Therefore, pig manure pollution is one of the important factors of environmental pollution in modern intensive farming one. [0003] Pig manure is actually an important biomass energy source. If it is developed, it can turn waste into treasure and produce clean energy, such as raising earthworms with pig manure, producing biogas through anaerobic fermentation of p...

Problems solved by technology

At present, most of the pig manure fuel is made of pig manure raw materials plus coal, straw, etc. through hot pressing. Most of them are columnar or granular finished products. The finished products are still easy to see the pig manure raw materials, which will bring certain psychological discomfort to users. It is not easy to promote and use, and the existing pig manure fuel is made by pressing method, and most of them have not been effectively sterilized, so there is a certain hidden danger of epidemic prevention
