Description
Technical field
The utility model relates to dust collection equipment technical field, is specifically related to rice hull ash recovery system in a kind of boiler of combusting rice hull.
Background technology
Paddy rice is the widest, maximum crops of output of cultivated area in the world.Approximately 200,000,000 tons of the nearly 6 Yi Dun，Er China total outputs of current whole world paddy total output.In paddy, rice husk accounts for 20%.Although the rice husk resource of China is very abundant, current utilization rate is very low.At rural area rice husk, be used to animals feed, but because its nutrient composition content is very low, add rice husk surface by the fine and close covering of lignin, crude fibre is tightly surrounded, so animals is taken in total digestibility, can only reach 5%-8%.Therefore rice husk major part abandons as refuse or is used as inferior fuel, and this is contaminated environment not only, and has caused the waste of resource.In cities and towns rice processing factory, a large amount of rice husks is piled up, and utilization rate is also very low, and the overwhelming majority is all directly burned.Because dioxide-containing silica in rice husk is higher, rice husk is difficult to sufficient combustion, so except discharging great amount of carbon dioxide, also produce a large amount of dust in atmosphere simultaneously.
At present, the technology of rice husk power generating reaches its maturity, and power generation project is promoted and come at home at present, and rice husk has become bioenergy by waste resource.But rice husk power generating, can leave a large amount of rice hull ash, and the accumulation of these rice hull ash has caused again new pollution and the wasting of resources.Moreover, in enterprises, utilizing combusting rice hull boiler, the dust that contains rice hull ash is also directly discharged in atmosphere.
Utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, rice hull ash recovery system in the boiler of the combusting rice hull that practicality is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
Rice hull ash recovery system in a kind of boiler of combusting rice hull, comprise boiler, sedimentation chimney, absorption chimney and absorption blower fan, the top of the top of described sedimentation chimney and absorption chimney is communicated with, the bottom of described sedimentation chimney is connected to the outlet flue of boiler, described absorption blower fan is connected to the bottom of absorption chimney, described absorption blower fan one end is connected to absorption chimney by absorption pipeline, the other end is connected with motor through decelerator, in described sedimentation chimney, be provided with shower, described sedimentation chimney bottom is connected to rice hull ash sedimentation basin by outlet slot, between described outlet slot and rice hull ash sedimentation basin, be provided with preliminary sedimentation groove, described preliminary sedimentation groove is provided with more than one, between each preliminary sedimentation groove, by a breach, be connected successively, described shower is connected to rice hull ash sedimentation basin through water pump, supernatant in rice hull ash sedimentation basin comes back to sedimentation chimney for the sedimentation of rice hull ash.
Described breach is positioned at the cell wall top of preliminary sedimentation groove, and the liquid through preliminary sedimentation groove precipitation upper back flows into rice hull ash sedimentation basin again and precipitates.
Described sedimentation chimney and absorption chimney are vertically installed on ground.
Described rice hull ash sedimentation basin and preliminary sedimentation groove locate below ground level.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, adopt sedimentation to process rice hull ash, and effective, pollution-free, whole system does not have the discharge of pollutant, energy-conserving and environment-protective.
