Abstract
The invention discloses a production process of wood pellet fuel. The production process comprises the following steps: storing raw materials in a storage yard, preliminarily screening, drying, performing cyclone separation, pelletizing and forming, and bagging and warehousing. Through the adoption of the manner, according to production process of wood pellet fuel, various wood materials are selected for processing and manufacturing, wastes can be utilized, the heat energy of general wood materials is increased, the air pollution is alleviated, and the environment is protected.
Description
Technical field
The present invention relates to biomass fuel field, particularly relate to a kind of Wood pellets production technique.
Background technology
In recent years, along with improving constantly of people's environmental consciousness, bioenergy technology is imperative, and the research and development of bioenergy technology have become one of great heat subject in the world, receive the concern of countries in the world government and scientist, many countries have all formulated corresponding development research plan.
In bioenergy, biomass fuel is a kind of important material, and biomass energy is the block environmental protection new forms of energy produced through processing by stalk, wood chip etc. " three surplus things ", and Wood pellets is exactly one wherein.
But present wooden fuel's production technology very imperfection, so people need the production technique more met the demands.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Wood pellets production technique, the advantage such as have that reliability is high, environmental protection, technique are simple, simultaneously biomass fuel application and universal on have market outlook widely.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
There is provided a kind of Wood pellets production technique, step comprises:
Starting material are layered on dry place and carry out airing by material storage yard: select sawdust, wood shavings, branch and wooden unit as starting material;
Preliminary screening: starting material cut or is ground into broken end or wood chip, broken end or wood chip being transported to sieve apparatus and sieving; Filter out broken end or wood chip that foreign material or diameter are greater than 4cm, cutting is re-started to the broken end filtered out or wood chip or pulverizes;
Dry: the material after screening to be transported to dryer by transfer roller and to carry out drying by hot blast, when the water ratio in material is at 8-10%, be judged as acceptable material;
Cyclonic separation: acceptable material is transported in pelletizing forming machine, and in the process transmitted, by separator, the moisture that each material produces is drained;
Pelletizing forming: utilize that each Material compression becomes diameter within the scope of 10mm-12mm by pelletizing forming machine, density is at 1.1t/m
3-1.3t/m
3finished particle in scope; The finished particle just produced is carried out cooling down to normal temperature, by separator, the moisture that each material produces is drained simultaneously; The collection acceptable material that is separated again is transported to pelletizing forming machine and carries out granulation again; Cooled finished particle is screened, sliver screen is elected, and particle is transported to again pelletizing forming machine and carries out granulation again;
Pack warehouse-in: the finished particle after processing is loaded in sealing bag and sends into stockyard.
