Abstract

The invention discloses a composite compact type biomass fuel and a preparation method thereof. The fuel comprises the following components in parts by weight: 15-70 parts of domestic garbage, 5-40 parts of restaurant garbage, 10-80 parts of drain sludge, 10-30 parts of human and poultry excrement and 10-30 parts of agriculture and forestry wastes, preferably, 25-35 parts of domestic garbage, 5-20 parts of restaurant garbage, 15-25 parts of drain sludge, 15-25 parts of human and poultry excrement and 15-25 parts of agriculture and forestry wastes. The obtained composite compact type biomass fuel can simultaneously treat the domestic garbage, the restaurant garbage, the agriculture and forestry wastes, the drain sludge and the human and poultry excrement and can be produced by a wet method at room temperature and normal pressure on a large scale without loss of heat value. In addition, the invention also provides the preparation method of the biomass fuel. The method is simple, practicable, clean and environment-friendly, is low in investment and operation cost, and has extremely obvious economic and environment-friendly benefits.

Description

technical field [0001] The invention relates to a biomass fuel, in particular to a composite dense biomass fuel and a preparation method thereof. Background technique [0002] With the sustained and rapid economic growth, the acceleration of urbanization and the improvement of people's living standards, the output of domestic waste has increased rapidly. According to statistics, by 2008, the annual volume of domestic garbage removal in China has reached 147 million tons, and it has increased by 8% to 10%. Over the years, the cumulative amount of domestic waste accumulated has reached 8 billion tons, occupying 500 million cubic meters of land, seriously polluting the atmosphere and groundwater resources, and even gas explosion accidents. Household garbage is not only a source of pollution to land, water and the atmosphere, but also a renewable resource. With the improvement of people's living standards, the content of inorganic substances in domestic waste has decreased an...
