Abstract
The utility model relates to a device for recycling organosilicone monomer synthesized waste silicon powder. The device comprises a fine silicon powder tank, a silicon-carbon separator, a high-efficiency cyclone separator and a receiving hopper, wherein one end of the silicon-carbon separator is connected with the fine silicon powder tank, while the other end of the silicon-carbon separator, the high-efficiency cyclone separator and the receiving hopper form a circulation system. The device also comprises a cutoff check valve, a screwing valve and a gas distributor, wherein the gas distributor is arranged at the bottom end of the silicon-carbon separator, the cutoff check valve is arranged at the lower end of the gas distributor, and the screwing valve is arranged between the silicon-carbon separator and the gas distributor. In order to lower the unit consumption of silicon powder, the small-sized silicon-carbon separator and the high-efficiency cyclone separator are arranged behind the fine powder tank so as to separate fine silicon powder from carbon particles; purified silicon powder returns into a silicon-carbon separating tank, so that the silicon powder can be further purified to serve as graphite powder and the like; the use value of products is enhanced; besides, the device is simple in whole structure, low in cost and convenient to use.
Description
Technical field
The utility model relates to organic silicon monomer production technical field, is specifically related to the recycle device of waste silicon powder in a kind of organic silicon monomer production process.
Background technology
Nineteen forty-one, first Rochow adopts direct synthesis organic silicon monomer (methylchlorosilane), and in synthetic reaction, solid material is silicon powder particle, and catalyst is copper powder particle, and gas raw material is chloromethanes, Gu course of reaction is gas-solid-reaction.The influence factor of direct synthesis organic silicon monomer is a lot, and material quality is a very important index.
Offshore company attaches great importance to the quality of silica flour, even the coke of smelting is had to requirement.Particle diameter on silica flour and distribution thereof, various metallic element and compound have more clearly understanding to the impact of reaction, and in the purity on silicon and silicon, impurity has had the concept of amount on the impact of synthetic reaction rate and diformazan content.Low, in-and-out situation when high while often there is diformazan yield when domestic production methylchlorosilane, its main cause is exactly to understand impurity in silicon, silica flour particle diameter and the impact distributing on reaction thereof not yet completely, so be difficult to control complicated synthetic reaction.Silica flour quality seriously perplexs the development that China's methylchlorosilane is produced.
At present, the domestic improvement of being mainly devoted to some front systems such as fluidized-bed reactor reduces energy consumption in improving the selective and yield of target product (dimethyldichlorosilane M2), less in processing research for rear system recoveries.The unit consumption of domestic production methyl chlorosilane monomer silica flour is generally 0.24
-between 0.28, the unit consumption of external silica flour is generally 0.22
-between 0.23.Energy Intensity Reduction is that enterprise produces important economic indicator of methylchlorosilane.
Utility model content
The utility model object is: for the problem of above-mentioned existence, provide a kind of utilization rate that can effectively improve silica flour, again can be cost-saving, and improve the recycling device of the use value of product.
The utility model object is achieved by the following technical solution:
A recycling device for the synthetic waste silicon powder of organic silicon monomer, comprises a fine silica powder tank 1, a silicon-carbon separator 2, an efficient cyclone separator 6, hopper 7; Described silicon-carbon separator 2 one end connect fine silica powder tank 1, and the other end and efficient cyclone separator 6, hopper 7 form a loop structure; Also comprise that a stop check valve 4, screws valve 5, a gas distributor 3, described gas distributor 3 is arranged on the bottom of silicon-carbon separator 2, described stop check valve 4 is arranged on the lower end of gas distributor 3, screws valve 5 and is arranged between silicon-carbon separator 2 and gas distributor 3.
Particularly, the gas that this retracting device uses is N
2.
Particularly, described efficient cyclone separator 6 is connected with and stores the container of carbon dust, described in screw valve 5 and be connected with the container that stores silica flour.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the utility model is in order to reduce the unit consumption of silica flour, after fine powder tank, add a small-sized silicon-carbon separator and an efficient cyclone separator device, by silicon-carbon separator and efficient cyclone separator, fine silica powder and carbon granule are separated, silica flour after purifying is back in silicon-carbon knockout drum again, carbon dust, through being further purified aspects such as can be used as graphite powder, has improved the use value of product again.
2, the utility model can, by reclaiming the useless powder of other producer, be saved the cost of material in production process.

Mark in figure: 1-fine silica powder tank, 2-silicon-carbon separator, 3-gas distributor, 4-stop check valve, 5-screws valve, 6-efficient cyclone separator, 7-hopper.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the recycling device of the synthetic waste silicon powder of a kind of organic silicon monomer, silica flour waste material enters fine silica powder tank 1, opens stop check valve 4, keeps screwing valve 5 and closes, and keeps N
2linear velocity reaches 0.05
-0.5m/s, passes through N
2fine silica powder in fine silica powder tank 1 is pressed onto in silicon-carbon separator 2, and fine silica powder is fluidisation in silicon-carbon separator 2, and because carbon powder particle is lighter than silicon powder particle, in efficient cyclone separator 6, carbon dust is with N
2get rid of, enter in the container of storage carbon dust; Bulky grain silica flour enters hopper 7, and recirculation enters silicon-carbon separator 2, continues logical N
20.5h
-5h, closes stop check valve 4, opens silicon-carbon separator 2 top N
2valve, fills N
2silica flour after purifying is pressed in the container that stores silica flour.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
