Abstract
The utility model discloses a gas distribution device of a trichlorosilane fluidized bed, which comprises a distribution board, wherein the distribution board penetrates through and is arranged on the side wall of a fluidized bed casing; a plurality of air outlet pipes penetrate through and are arranged on the distribution board at intervals; and blast caps penetrate through and are arranged at the lower ends of the air outlet pipes. According to the gas distribution device, by adopting the technical scheme that the air outlet pipes penetrate through and are arranged on the distribution board at intervals and the blast caps penetrate through and are arranged at the lower ends of the air outlet pipes, the blast caps cannot be blocked and blown off and have a longer service life.
Description
Technical field
The utility model relates to a kind of trichlorosilane fluidized-bed, relates in particular to a kind of distribution device in gas-fluid of trichlorosilane fluidized-bed.
Background technology
Trichlorosilane is the important source material of producing polysilicon at present, is the raw material basis of photovoltaic industry, also is the raw material basis of exploitation and development new forms of energy-environmental protection energy.Just present, the exploitation development environment-friendly type energy is global developing direction, so trichlorosilane has vast market prospect.
The production technique of trichlorosilane is as follows:
1) with exsiccant hydrogenchloride and silica flour;
2) in the trichlorosilane fluidized-bed, react generation trichlorosilane and a spot of silicon tetrachloride and hydrogen under 300 ℃ the situation;
3) through dedusting, condensation, tail gas absorbs;
4) lime set rectifying gets product trichlorosilane and by-product silicon tetrachloride.
In production process of trichlorosilane; the trichlorosilane fluidized-bed is main production unit; wherein the distribution device in gas-fluid of trichlorosilane fluidized-bed is a trichlorosilane fluidized-bed vitals; the board-like blast cap side opening grid distributor of the general employing of the distribution device in gas-fluid of current trichlorosilane fluidized-bed; often have some blast cap holes and blocked, blown brokenly.
The utility model content
The utility model is at deficiency of the prior art, and a kind of distribution device in gas-fluid of trichlorosilane fluidized-bed simple in structure is provided, and uses its blast cap of distribution device in gas-fluid of this trichlorosilane fluidized-bed can not blocked and blow brokenly, has long work-ing life.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of distribution device in gas-fluid of trichlorosilane fluidized-bed comprises grid distributor, and described grid distributor is located on the sidewall of fluidized-bed housing, is equipped with several escape pipes at interval on the described grid distributor, and the lower end of described escape pipe is equipped with blast cap.
In the technique scheme, the number of described escape pipe is 15～25.
In the technique scheme, described escape pipe is the right cylinder of hollow.
In the technique scheme, the sidewall of described housing is provided with gasket corresponding to the grid distributor place.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
The utility model wears several escape pipes at interval by adopting on grid distributor, and the lower end of described escape pipe is equipped with the technical scheme of blast cap, makes blast cap can not blocked and blow brokenly, has long work-ing life.
Description of drawings
Fig. 1 is the structural representation of trichlorosilane fluidized-bed.
Fig. 2 is the structural representation of the distribution device in gas-fluid of trichlorosilane fluidized-bed.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1～2, a kind of distribution device in gas-fluid of trichlorosilane fluidized-bed comprises grid distributor 3, and described grid distributor 3 is located on the sidewall of fluidized-bed housing 1, is equipped with 21 escape pipes 5 on the described grid distributor 3 at interval.The number of certain described escape pipe 5 can be made suitable adjustment in size by root a tree name fluidized-bed.In general, it is suitable that escape pipe 5 is typically provided to 15～25, because number too much can cause the aperture of escape pipe 5 to reduce, is unfavorable for gas flow, if number is very few, then causes the gas distribution inequality easily.
Described escape pipe 5 is the right cylinder of hollow, and the lower end of described escape pipe 5 is equipped with blast cap 7.
Preferably, the sidewall of described housing 1 is provided with gasket corresponding to grid distributor 3 places.
Owing to be with board-like blast cap 7 side opening grid distributors 3 in the past, often there are indivedual blast caps 7 holes to be blocked, blown brokenly.This fluidized-bed facts have proved: the distribution device in gas-fluid of trichlorosilane fluidized-bed, its blast cap 7 can not blocked and be blown brokenly, has long work-ing life.
