Abstract
The utility model discloses a trichlorosilane fluidized bed, which comprises a casing, wherein an oil inlet tank and an oil outlet tank are sequentially arranged on the inner surface at the upper end of the casing from top to bottom; the oil inlet tank is provided with an oil inlet; the oil outlet tank is provided with an oil outlet; and the oil inlet is arranged above the casing. According to the trichlorosilane fluidized bed, by arranging the oil inlet above the casing, the trichlorosilane fluidized bed has a more reasonable and simpler structure and is convenient and practical.
Description
Technical field
The utility model relates to a kind of trichlorosilane fluidized-bed, relates in particular to a kind of trichlorosilane fluidized bed heat exchanger device.
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, current trichlorosilane fluidized-bed, comprise housing, the internal surface of described housing upper end is disposed with oil-feed tank from top to bottom, goes out fuel tank, described oil-feed tank has oil-in, goes out fuel tank and has 2 oil outlets, and described oil-in is arranged on the side of housing.Described oil-in and oil outlet all are arranged on the same pipeline.That is to say that described oil-in and oil outlet are big annular tube type turnover oil.Its complex structure is made inconvenient.
The utility model content
The utility model provides a kind of structure more reasonable, simple, convenient, handy trichlorosilane fluidized-bed at deficiency of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The trichlorosilane fluidized-bed comprises housing, and the internal surface of described housing upper end is disposed with oil-feed tank from top to bottom, goes out fuel tank, and described oil-feed tank has oil-in, goes out fuel tank and has oil outlet, and described oil-in is arranged on the top of housing.
In the technique scheme, described oil-in be arranged on housing directly over.
In the technique scheme, described oil outlet is provided with 2.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
The utility model since with oil-in be arranged on housing directly over, make structure more reasonable, simple, convenient, handy.
Description of drawings
Fig. 1 is the structural representation of trichlorosilane fluidized bed heat exchanger device.
Fig. 2 is an I place enlarged view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1～2, the trichlorosilane fluidized-bed comprises housing 1, the internal surface of described housing 1 upper end is disposed with oil-feed tank 3 from top to bottom, goes out fuel tank 5, described oil-feed tank 3 has oil-in 7, go out fuel tank 5 and have 2 oil outlets 9, described oil-in 7 be arranged on housing 1 directly over.
The utility model since with oil-in 7 be arranged on housing 1 directly over, oil-in 7 and oil outlet were arranged in 9 minutes, make the utility model structure more reasonable, simple, convenient, handy.
