Abstract
The invention relates to a rice husk turbulent burner comprising a secondary air duct assembly and a rice husk pipe assembly, wherein, the secondary air duct assembly is composed of a secondary air inlet, a secondary air duct barrel and secondary air side blades, wherein, the secondary air inlet is connected with the secondary air pipe barrel; the secondary air side blades are uniformly arranged on the secondary air duct barrel at the circumference; the rice husk pipe assembly is composed of a rice husk feeding hole, a rice husk pipe barrel, a peeping hole pipe and rice husk side blades, wherein, the rice husk feeding hole is connected with the rice husk pipe barrel; the rice husk side blades are uniformly arranged on the rice husk pipe barrel at the circumference, and are fixed on a peeping blank pipe through insertion strips; and the secondary air side blades are fixed on the rice husk pipe barrel. The rice husk turbulent burner of the invention can ensure low rice husk to be burnt thoroughly, can flexibly adjust the mixing proportion of the rice husk and the air according to the rice husk humidity, and can ensure the proportioning of the rice husk and the air as well as uniform mixture, thus leading the gas-solid mixture in a chamber to be more uniform and stronger, and being beneficial for burning the rice husk.
Description
Technical field
The present invention relates to a kind of rice husk turbulent burner, belong to the Industrial Boiler Technology field.
Background technology
The energy is human survival and supports the indispensable pillar of mankind's socio-economic development.Minimizing year by year along with minable fossil energy on the earth; and people are to the reinforcement of environmental protection consciousness; the waste combustible materials matter that another kind is produced aborning; the research interest that is biomass fuel progressively improves, and this class A fuel A comprises: rice husk, bark, bagasse and coconut husk, cocoa shell etc.Use the biomass energy of the Nature present, produce hardly and pollute, resource is renewable and can be exhausted, and the important function that plays protection simultaneously and improve the ecological environment is one of desirable regenerative resource.According to statistics, world energy sources 1/7th from the biological energy source that plant had, be to be only second to oil, coal and natural gas, occupy the 4th the energy.Become main biomass fuel at China's rice husk.Existing large-scale rice husk combustion technology mainly is fluid bed chaff-fired boiler and fire grate chaff-fired boiler, but fluidized bed combustion rice husk system is comparatively complicated, the cost of investment height, and stable operation is difficult, is unfavorable for the large tracts of land popularization; Existing furnace grate burning mainly is grate firing and the suspension combustion technology that adopts on the grate surface, the former grate firing belongs to single face and catches fire, air distribution is inhomogeneous, though belonging to multiaspect, latter's suspension combustion catches fire, air distribution is comparatively abundant, but because there is the dead angle in reasons in structure secondary wind flow field, cause the suspension combustion combustion position of can not realizing ideal in whole burner hearth, efficiency of combustion is not high.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of rice husk turbulent burner, this burner adopts rice husk and air to shift to an earlier date mixed uniformly combustion system, can guarantee that low rice husk thoroughly burns, and can be according to rice husk humidity flexible modulation rice husk and Air mixing ratio.
According to technical scheme provided by the invention, a kind of rice husk turbulent burner comprises secondary air channel assembly and rice husk pipe assembly, and rice husk pipe assembly is installed in the secondary air channel assembly; Described secondary air channel assembly is made up of secondary wind inlet, secondary air channel cylindrical shell and secondary wind lateral lobe sheet, and the secondary wind inlet connects the secondary air channel cylindrical shell, evenly is provided with secondary wind lateral lobe sheet by circumference on the secondary air channel cylindrical shell; Described rice husk pipe assembly is made up of rice husk charging aperture, rice husk tube cylinder, peephole pipe and rice husk lateral lobe sheet, and described rice husk charging aperture connects the rice husk tube cylinder, evenly is provided with rice husk lateral lobe sheet by circumference on the rice husk tube cylinder; Be provided with in the rice husk tube cylinder and peep blank pipe, rice husk lateral lobe sheet is fixed on by filler rod and peeps on the blank pipe, and secondary wind lateral lobe sheet is fixed on the rice husk tube cylinder.
Described secondary wind lateral lobe sheet and rice husk lateral lobe sheet are respectively helical form, are made as 6～8.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Adopt rice husk and air to shift to an earlier date mixed uniformly combustion system, utilize adjusting main air intake and secondary wind air door to control rice husk amount and secondary air flow, not only can guarantee the proportioning of rice husk and air, simultaneously can guarantee to mix, make the gas-solid mixing in the thorax more even, strong, help burning.
Description of drawings
Fig. 1 is a cutaway view of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
