Abstract
The invention provides an improved soot cleaning device of an inlet flue duct of a cyclone separator of a circulating fluidized bed boiler, which can ensure no soot agglomeration during the using process and further ensure the separation efficiency of the separator. The improved soot cleaning device comprises the cyclone separator and is characterized in that air main pipes are arranged on two sides of the bottom of the inlet flue duct of the cyclone separator respectively, the two air main pipes are connected through a connecting pipeline, the air main pipes are connected with an external compressed air device, nozzles are arranged on inner sides of the two air main pipes and one side of the connecting pipeline which is near to the cyclone separator, and air outlets of the nozzles are tilted to the direction of the cyclone separator.
Description
(1) technical field
The present invention relates to the circulating fluid bed garbage furnace apparatus field, be specially a kind of inlet flue duct of cyclone separator of circulating fluidized bed boiler deashing device of improvement.
(2) background technology
The inlet flue duct of existing cyclone separator of circulating fluidized bed boiler is in the accumulation that is prone to cause a large amount of ashes in the use, thereby changes the air velocity distribution that gets into cyclone separator, the inner concentrated wear of accelerating separtor, the separative efficiency of reduction separator.
(3) summary of the invention
To the problems referred to above, the invention provides a kind of inlet flue duct of cyclone separator of circulating fluidized bed boiler deashing device of improvement, grey phenomenon is not in use tied in its assurance, thereby guarantees the separative efficiency of separator.
Its technical scheme is such: it comprises cyclone separator; It is characterized in that: the both sides of the inlet flue duct bottom of said cyclone separator are equipped with the female pipe of air respectively; The female pipe of said two air connects through connecting pipeline; The female pipe of said air connects outside blowing plant, and inboard, the said connection pipeline of the female pipe of said two air are equipped with nozzle near said cyclone separator one side, and said nozzle air outlet tilts towards said cyclone separator direction.
It is further characterized in that: said blowing plant specifically comprises wireway, valve, Pressure gauge, and a female pipe in the female pipe of said two air connects compressed air through wireway, and valve, Pressure gauge are installed on the said wireway.
In the said structure of the present invention; After blowing plant blows to the female pipe of said air, said tube connector with compressed air; Compressed air is gone out from the air outlet of said nozzle, because said nozzle air outlet tilts towards said cyclone separator direction, its ash with remnants all blows to said cyclone separator; Can not tie grey phenomenon so the inlet flue duct of said cyclone separator is in the use, thereby guarantee the separative efficiency of separator.
(4) description of drawings
Fig. 1 is a stereogram structural representation of the present invention.
(5) specific embodiment
See Fig. 1; The present invention includes cyclone separator 1; The both sides of the inlet flue duct bottom 2 of cyclone separator 1 are equipped with the female pipe 3,4 of air respectively; Two female pipes 3,4 of air pass through to connect pipeline 5 and connect, and the inboard of two female pipes 3,4 of air, connection pipeline 5 are equipped with nozzle 6 near cyclone separator 1 one sides, and nozzle 6 air outlets tilt towards cyclone separator 1 direction.The female pipe 3 of air connects compressed air through wireway 7, and valve 8, Pressure gauge 9 are installed on the wireway 7.
Claims (1)
1. the inlet flue duct of cyclone separator of circulating fluidized bed boiler deashing device of an improvement; It comprises cyclone separator; It is characterized in that: the both sides of the inlet flue duct bottom of said cyclone separator are equipped with the female pipe of air respectively; The female pipe of said two air connects through connecting pipeline; The female pipe of said air connects outside blowing plant, and inboard, the said connection pipeline of the female pipe of said two air are equipped with nozzle near said cyclone separator one side, and said nozzle air outlet tilts towards said cyclone separator direction; Said blowing plant specifically comprises wireway, valve, Pressure gauge, and a female pipe in the female pipe of said two air connects compressed air through wireway, and said valve, Pressure gauge are installed on said wireway.
