Abstract
The invention discloses a multi-stage dust remover comprising a gravity dust remover, a cyclone dust remover, a filter bag and a casing, and further comprising an air inlet, a connector, and an air outlet, wherein the gravity dust remover comprises a settling chamber below which a dust collecting chamber is arranged; and a dust outlet is formed at the bottom of the dust collecting chamber; and the cyclone dust remover comprises a cyclone dust removing chamber, inside which a discharge pipe is arranged, a dust collecting chamber is arranged below the cyclone dust removing chamber, and a dust outlet is formed at the bottom of the dust collecting chamber. Due to the adoption of the way, the multi-stage dust remover is suitable for a biomass gasifier, can effectively remove the dust of the cracked biomass gas, and has high dust removing efficiency.
Description
Technical field
The present invention relates to the deduster field, particularly relate to a kind of deduster that is used for biomass gasifying furnace.
Background technology
The energy is the material base that the mankind depend on for existence, is the basic support of national economy.China is energy-consuming big country; Fossil energies such as coal, oil, natural gas are mainly leaned in current energy supply; And the finiteness of fossil energy resource with and the development and use process in immense pressure that environmental ecology is caused, seriously restricting continuous development of society economy.Simultaneously, China is again a large agricultural country, has every year plant biomass such as a large amount of agricultural crop straws, feces of livestock and poultry, processing of farm products byproduct and energy crop to produce.
And biomass gasification technology is raw material just with the plant biomass; Adopt pyrolysismethod and heat chemistry oxidizing process under anoxia condition, to heat; Make it that conversion process of energy of complicated thermal chemical reaction take place; Under reaction condition,, become the molecule of imflammable gas such as carbon monoxide, methane, hydrogen according to the one-tenth key principle of chemical bond.Finally utilize these gases to carry out central gas supply, generating, thereby can substitute existing coal electricity and natural gas in some cases.It has not only alleviated because of the crop straw burning pollution on the environment, and has improved the effect of utilizing of stalk, and has proposed effective way for the sustainable development of the energy.
Dust is owing to the pollution of environment and to the injury of human body, become one of subject matter of restriction biomass gasification technology development.If can not carry out dedusting to biogas, dust can be discharged into after burning in the air, and fine particulates can get into the lung of human body, influences the health of human body.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of multistage rotary dust collector, and the biogas that can counterincision solves carries out effective dedusting, and efficiency of dust collection is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of multistage rotary dust collector is provided, comprises: gravitational precipitator, cyclone dust collectors; Filter bag and housing also comprise, air inlet, connector; The gas outlet, said gravitational precipitator comprises expansion chamber, the ash accumulating chamber of expansion chamber below, the dust export of ash accumulating chamber bottom; Said cyclone dust collectors comprise the cyclone dust removal chamber, the discharge pipe of cyclone dust removal chamber interior, the ash accumulating chamber of below, cyclone dust removal chamber, the dust export of ash accumulating chamber bottom.
In preferred embodiment of the present invention, a baffle plate is arranged in the expansion chamber of said gravitational precipitator.
In preferred embodiment of the present invention, the material of said inner walls is resistant to elevated temperatures basalt fibre.
In preferred embodiment of the present invention, said connector and cyclone dust collectors adopt the tangential admission mode.
The invention has the beneficial effects as follows: the present invention adopts multistage dust removal design, and the biogas that can counterincision solves carries out effective dedusting, and efficiency of dust collection is high.
