Continuous reproduction technology using biomass wastes and waste liquid

Abstract

The invention provides a continuous reproduction technology using biomass wastes and a waste liquid. The technology comprises the following steps: crushing the biomass wastes, drying, molding, sending the obtained biomass wastes to a dry distillation furnace, and carrying out dry distillation to obtain charcoal and crude dry distillation gas; cooling charcoal, packaging to obtain a finished product, condensing the crude dry distillation gas to obtain a gas phase which is biogas, carrying out alkaline washing, separating, conveying to make the biogas enter a gas storage cabinet, and allowing the biogas to enter users through a pipe network; standing a refluxing waste liquid obtained after condensation of the crude dry distillation gas to realize layering and obtain an upper layer which is wood vinegar and a lower layer which is wood tar, collecting the wood tar, and packaging the collected wood tar to obtain a finished product; and determining organic matter components of the wood vinegar through gas chromatography-mass spectrometry, and respectively preparing a bacteriostasis and deodorization agent and an environmentally friendly botanical snow melting agent according to the content of acetic acid. The technology has the characteristics of continuousness, no emission of the waste liquid, and environmental protection, and solves the high value utilization problem of the waste liquid generated in the preparation of gas through biomass pyrolysis; and the bacteriostasis and deodorization agent has strong bacteriostasis, the ammonia odor removal rate can reach 100%, and the snow melting agent has the advantages of no corrosion, low snow melting temperature, chlorine harm eradication and excellent environmental protection performance.

Description

technical field [0001] The invention belongs to the field of biomass energy development, and in particular relates to a biomass pyrolysis gasification technology which can continuously use backflow waste liquid for high-value utilization while utilizing biomass waste carbonization and pyrolysis to produce carbon. Background technique [0002] Biomass energy is fixed carbon dioxide and water by plants through photosynthesis, and stores solar energy in plants in the form of chemical energy. It is the most abundant and widely distributed renewable resource in nature. Biomass waste mainly comes from forest tending branches and wood processing residues, shavings, sawdust, and agricultural residues such as straw and fruit shells. The development and use of biomass energy can not only obtain alternative energy with stable sources and safe supply, but also It can reduce dependence on fossil fuels, so biomass energy is an internationally recognized clean fuel.
