Abstract
The utility model discloses a chloride propyl silane recovery device which comprises a buffering tank, a receiving tank, a primary condenser, a secondary condenser and a tertiary condenser, wherein the primary condenser, the secondary condenser and the tertiary condenser are sequentially communicated, the buffering tank is communicated with the primary condenser, and the primary condenser and the secondary condenser are further communicated with the receiving tank. The chloride propyl silane recovery device can effectively absorb trichlorosilane and recover chloride propyl silane in materials, greatly reduces pollution emission, saves cost, and improves produce efficiency of the chloride propyl silane.
Description
Technical field
The utility model relates to the retrieving arrangement field, is specially a kind of chlorine Trisilicopropane retrieving arrangement.
Background technology
Producing chloropropyl silane desired raw material is trichlorosilane, propenyl chloride and alcohol, passes through first addition reaction of silicon with hydrogen, generates chloropropyl trichloro-silane, and then carries out esterification, and the finished product are chloropropyl silane.The boiling point of trichlorosilane and propenyl chloride is lower; the lossy situation of unavoidable meeting in the process of producing; recovery method according to cold your device of routine; effect is not very desirable, and the loss of volatilization is nearly 10%, and trichlorosilane character is very active; as long as running into water will be hydrolyzed immediately; product after the hydrolysis has hydrogen chloride gas and polymkeric substance, and environment is caused larger pollution, and Working environment and corresponding hardware are caused larger corrosion.Simultaneously, be easy to produce a large amount of hydrolysates in the outlet of emptying, block the emptying outlet, production is affected.
The utility model content
The utility model purpose provides a kind of chlorine Trisilicopropane retrieving arrangement, produces the problem that trichlorosilane is difficult for recovery when prior art is produced the chlorine Trisilicopropane to solve.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
Chlorine Trisilicopropane retrieving arrangement, it is characterized in that: comprise surge tank, receiving tank, and three grades of condensers that are communicated with successively, described surge tank input aperture is connected with the material input tube, the surge tank delivery port is communicated with first step condenser input aperture by pipeline, third stage condenser delivery port is connected with vapor pipe, and wherein first, second grade condenser also is communicated with receiving tank by pipeline respectively.
The utility model can absorb trichlorosilane effectively, and finishes the recovery to chlorine Trisilicopropane in the material, greatly reduces the discharging of pollution, has saved cost, has improved chlorine Trisilicopropane generation efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1.Chlorine Trisilicopropane retrieving arrangement, comprise surge tank A, receiving tank E, and three grades of condenser B, C, D that are communicated with successively, surge tank A input aperture is connected with the material input tube, surge tank A delivery port is communicated with first step condenser B input aperture by pipeline, third stage condenser C delivery port is connected with vapor pipe, and wherein first, second grade condenser B, C also are communicated with receiving tank E by pipeline respectively.
Material at first enters surge tank A, then enters first step condenser B.The cooling temperature of first step condenser B is-10 ℃, and this process has and enters receiving tank E after being cooled more than 90%, and remainder is cooling not, will again still enter receiving tank E by second stage condenser C.The cooling temperature of second stage condenser C reaches-15 ℃ by freezing treatment, this process is processed the material of about 8-9%, will be by third stage condenser D through the part that is not cooled in the vapor-phase material behind the condenser C of the second stage, the cooling temperature of third stage condenser D reaches-20 ℃ by freezing treatment, to in the end do the reinforcement cooling process through the material that twice refrigerated condensation is not cooled, the tail gas of minute quantity enters soda-wash tower and absorbs processing.
