Abstract
The invention discloses a straw carbonization and separation technique and a separating device used thereby to realize the carbonization of the straw and extract various useful substances, such as wood tar oil, wood vinegar, mixed combustible gas and the like in a carbonization process. The technique comprises the following steps of: processing the straw into segmented straw, sending the segmented straw into a furnace kiln and igniting to heat the segmented straw at a high temperature to produce smoke gas and placing the treated straw into a sharp quenching multi-pipe separating device to extract wood tar oil; extracting mixture of wood tar oil and wood vinegar liquid in a multi-layer staggered separating device; extracting wood vinegar liquid in an internal rotation centrifugal separating device; and sending remaining gas into a purification tower to purify and controlling the temperature to be between 60 and 80 DEG C. The invention has the advantages that: a new straw carbonization and separation technique is developed and the extraction of various useful substances, such as wood tar oil, wood vinegar and mixed combustible gas, is realized when bio-carbon is produced.
Description
Technical field
The present invention relates to straw-carbonized, separating technology, is a kind of processing method innovation that material carbonizations such as stalk is formed biological coal.
Background technology
About 1,700 hundred million tons of the biomass that annual process photosynthesis produces on the earth, its energy that contains roughly is equivalent to 10 times that world's main fuel consumes, and the utilization of the seat energy is less than 1% of its total amount.The large agricultural country in China seat, about 700,000,000 tons of annual agricultural crop straw amount is equivalent to 3.5 hundred million tons of carbon coals.Straw power generation, the project of utilizing the agricultural crop straw contain xylogen, agriculture and forestry organic waste material etc. to act as a fuel and generate electricity exactly.Utilize straw power generation, at first can directly avoid agricultural crop straw directly to burn the atmospheric pollution that brings in the field.Agricultural crop straw was except life of farmers was personal in the past, and remaining utilizes mainly is to do feed, papermaking, several modes in field also.Also more to the research of gasifying stalk in recent years, but countryside and peasantry life now is personal, and to connect solid food fewer and feweri, and the stalk amount of feed utilisation is very little, stalk papermaking causes very big pollution to ecotope, close in little paper mill, most of areas, big paper mill no longer utilizes stalk to be raw material, and also the field increases peasant's cost, and field effect is also bad, and real commercial applications is still failed in the research that stalk is made biogas and gasification.Like this, discarded in a large number stalk has to be burnt in the field by the peasant, and serious environment pollution causes a series of problems such as traffic, fire.Utilize straw power generation, can effectively deal with problems.Secondly, the circular form economy of straw power generation load country proposition, the state basic policy of Sustainable development.Hunger sensation is reproducible biomass energy, compared with Nonrenewable energy resources such as coal, oil, can be described as inexhaustible, use not to the utmost, cyclic regeneration.To optimizing the energy structure in the China and even the world, important meaning is arranged all.In addition, straw power generation can also promote the development of local economy, increases peasant's income.Help country to solve the agriculture, rural areas and farmers problem, protection environment and promotion harmonious society.After the scale production, can increase local rates, create more jobs in addition, play a role in promoting for local related industries.The present invention finds out new straw-carbonized, the separating technology of a cover exactly through concentrating on studies exploitation.
Summary of the invention
