Problems solved by technology

These methods have the following disadvantages: 1. adopt the method of landfill, this method will take up a large amount of land, and the organic matter, heavy metal, bacteria etc. in the sludge will pollute the groundwater; It is safe, affects human health, and will cause secondary pollution; 3. There are also sludges that are dried and used as fuel. However, using sludge as fuel is complicated in the production process and high in cost, and cannot be used in industrial production
[0004] At present, there are also bio-synthetic charcoal made by mixing sludge and biomass fuel. Because this method does not sterilize and deodorize the synthetic charcoal, it will cause diseases and insect pests, bacteria, and odors in the synthetic charcoal during transportation. Air spreads everywhere, causing secondary pollution
In addition, the synthetic carbon prepared by this method has a large sludge content, and the carbon content in the sludge is low. Even if a small amount of carbon powder is added, the calorific value of the synthetic carbon is not high due to the short combustion time of the carbon powder. high

Abstract

The invention relates to a preparation method of biomass sludge regenerated fuel charcoal. The method comprises the following steps: taking sludge, deodorizing, sterilizing, grinding biomass fuels, mixing the two materials, performing high temperature sterilization, and screening to obtain a product. The method can be adopted to dispose and comprehensively utilize sludge and waste biomass fuels; and the prepared fuel charcoal is environmentally-friendly and low in ignition point. The combustion products of the fuel charcoal are fewer and have low sulfur content. The method can be used for fully utilizing sludge and various wastes (biomass fuels), thus the purposes of energy conservation, emission reduction and development of circular economy can be realized.

Description

technical field [0001] The invention relates to a preparation method of biomass sludge regenerated fuel charcoal. Background technique [0002] Biomass fuels are rivers, lakes, floating wastes containing cellulose, hemicellulose and lignin, as well as wastes with cellulose, hemicellulose and lignin in industrial and agricultural production, bamboo, Wood, waste from environmental gardens, forestry pruning and felling, various woody wastes generated in daily life, various agricultural wastes and straws generated in agricultural production, etc. These biomass fuels are usually not treated as garbage, and are often discarded in the garbage Field or field, causing environmental pollution. [0003] In addition, a large amount of sludge produced by sewage treatment in daily life and industrial production (such as solid, semi-solid, semi-liquid waste such as organic matter, heavy metals, and bacteria produced in the process of sewage treatment) brings another kind of ecology Envir...
