Abstract

The invention relates to a dehydration process and equipment for a biomass solid, and belongs to the technical field of biomass dehydration. The invention aims at provided with a dehydration process and the equipment which have the advantages that slight energy source is consumed, the cells in the biomass solid are ruptured, the moisture is dissolved out, the water ratio of the biomass solid is greatly reduced, and the burning value of the biomass solid is improved. The technical scheme adopted by the dehydration process for the biomass solid is as follows: the dehydration process is performed according to the following steps of: 1, fracturing the biomass solid; 2, filtering the biomass solid after fracture; 3, putting the biomass solid into a heating unit, heating, and then entering a pressure container to stay for 10 minutes, thus obtaining a biomass solid cracking liquid; 4, putting the biomass solid cracking liquid into a cooling unit and cooling; and 5, entering a water extractor and carrying out dehydration. The dehydration process and equipment provided by the invention are especially suitable for carrying out dehydration treatment on the biomass solid with higher water ratio.

Description

technical field [0001] The invention relates to a dehydration process and equipment for biomass solids, belonging to the technical field of biomass dehydration. Background technique [0002] Biomass refers to various organisms formed through photosynthesis, including all animals, plants and microorganisms. The so-called biomass energy is the energy form of solar energy stored in biomass in the form of chemical energy. It is directly or indirectly derived from the photosynthesis of green plants and can be converted into conventional solid, liquid and gaseous fuels. Inexhaustible and inexhaustible, it is a renewable energy source and the only renewable carbon source. At present, many countries are actively researching and developing biomass energy. Biomass can be stored in organic matter that can grow, such as plants, animals and microorganisms, usually including wood, forest waste, agricultural waste, aquatic plants, oil plants, urban and industrial organic waste, animal ma...
