Abstract
The utility model relates to a high efficiency fine powder separation device used for separating the pulverized coal slag. An exhaust pipe is arranged in an outer shell which is connected with a cone which is connected with an ash hopper; an ash inlet pipe is connected between the outer shell and the exhaust pipe along the tangential direction. The utility model is characterized in that the bottom of the exhaust pipe is provided with a shutter which is connected with a rotational flow guide. The utility model has the advantages of simple structure, and convenient operation. After the powder enters the fine separation device, due to the centrifugal function and the gravitational function, the mixed flow is separated, and the powdered coal enters an ash collecting hopper downward along the outer cylinder wall; the separation efficiency can be improved by more than 10%, and the resistance is lowered by about 30%.
Description
A kind of efficient fine powder separator is used for the separation to the coal dust slag.
Before the utility model is made, in prior art, this pulverized-coal collector adopts shell to insert cone, cone is inserted flue-dust retainer and is connected with it, the upper tube interface links to each other with blast pipe in the back insertion shell body, spiral plate is adopted in the upper end, and the lower end connects two assemblies respectively with stay pipe, tangentially taps into tube cell again between shell and blast pipe.This kind structure makes coal dust can not enter collection powder bucket equably, and separative efficiency is low, the resistance height.
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of simple in structure, and separative efficiency is low, the efficient fine powder separator that resistance descends.
The utility model adopts blast pipe 7 to be installed in the shell 6, shell 6 is connected with cone 11, and cone 11 connects flue-dust retainers 13, tangentially is connected powder inlet pipe 3 between shell 6 and the blast pipe 7, it is characterized in that blast pipe 7 bottoms installation shutter 8, shutter 8 connects eddy flow air deflectors 9.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts blast pipe 7 to be installed in the shell 6, explosion proof door 1 is installed on the blast pipe 7, and exhaust port 2 is housed, and spiral plate 5 is installed on blast pipe 7 and the shell 6, adopts stay pipes 10 to support in the shell 6.Explosion proof door 4 is installed on the shell 6 simultaneously, is tangentially tapped into tube cell 3 between shell 6 and the blast pipe 7; Shutter 8 is installed in blast pipe 7 bottoms, and shutter 8 connects eddy flow air deflector 9, and shell 6 is connected with cone 11, and radiation shield 12 is installed in cone 11 lower ends, and cone 11 connects flue-dust retainer 13.
Operation principle of the present utility model:
After the coal dust air Mixture flows to pulverized-coal collector, because the effect of centrifugal and gravity, mixed airflow is separated, coal dust enters flue-dust retainer downwards along outer tube wall, containing the less relatively air-flow of powder descends along the inner tank theca spiral, through the isobaric enrichment region that forms by shutter, air in the air-flow enters inner core, the coal dust of carrying secretly continues to move downward, after spiral air flow arrives the Outer Taper top, be folded to still and rise, before entering inner barrel, enter the air-flow of inner barrel because direction through the gas of cyclone and by shutter earlier with the helix rotation, factors such as angle produce bump.Air-flow is deviate from helix simultaneously, become the air of comparison " cleaning " by inner barrel top drain separator, the taper radiation shield that is installed in the bottom pyramid tip at meal outlet along having formed specific coal dust stocking angle garden week, make coal dust can enter collection powder bucket equably, when the bevel-type flapper is opened, leaked-in air promptly is reflected back on collection powder bucket top, then can not directly enter separator inside, has so just avoided effectively because of the leak out influence of tertiary air band powder that separation process is caused of flapper.
Compared with the prior art the utility model also has the following advantages: 1, simple in structure, easy to use; 2, after coal dust entered fine separator, because centrifugal and action of gravitation, mixed airflow was separated, coal dust Enter flue-dust retainer downwards along outer tube wall, separative efficiency can improve more than 10%, and resistance descends about 30%.
