Problems solved by technology

In addition, charcoal is coked due to high temperature during the combustion process, and about 10-20% of the charcoal is discarded without burning out, which wastes a lot of energy and produces a large amount of carbon dioxide, which directly causes economic losses and environmental pollution.
[0003] At present, there is a large amount of sawdust and waste wood in my country that cannot be effectively utilized. Therefore, it is necessary to develop a renewable, energy-saving and environmentally friendly charcoal that is produced using sawdust and waste wood.

Abstract

The invention relates to the technical field of charcoal, in particular to regenerative energy-saving environment-friendly charcoal and a preparation method thereof. The regenerative energy-saving environment-friendly charcoal is prepared from, by weight, 2%-4% of magnesium hydrate, 4%-8% of calcium oxide, 0.4%-0.6% of glass powder, 0.1%-0.3% of catalyst and the balance sawdust and waste wood. According to the regenerative energy-saving environment-friendly charcoal, 90% or above of carbon dioxide and sulfur dioxide generated during combustion of the charcoal can be removed effectively, and environment friendliness are achieved. The problem that close burning is caused by high temperature in the combustion process of biomass fuel can be solved, carbon dioxide and other harmful gas generated in the combustion process of the biomass fuel can be removed, energy waste is reduced, and energy saving and environment friendliness are really achieved. Waste materials are adopted, the charcoal can be regenerated, and good sustainable development prospects are achieved. The regenerative energy-saving environment-friendly charcoal is converted into matter like calcium carbonate after being combusted, the matter can be used as raw materials for producing various kinds of fertilizer, and a large quantity of resources is saved.

Description

technical field [0001] The invention relates to the technical field of charcoal, in particular to a regenerative energy-saving and environment-friendly charcoal and a preparation method thereof. Background technique [0002] Charcoal has the advantages of high calorific value and easy combustion, and is used in some living areas such as barbecues. Untreated charcoal produces a large amount of harmful gases such as carbon dioxide and sulfur dioxide during the combustion process, and also produces a large amount of white solids. Dust, directly discharged into the atmosphere will destroy the ozone layer and seriously pollute the earth's environment. It is one of the energy sources with serious environmental pollution and directly affects human health and plant growth. In addition, charcoal is coked due to high temperature during the combustion process, and about 10-20% of the charcoal is discarded without burning out, which wastes a lot of energy and produces a large amount of ...
