Abstract
The utility model discloses a desorption tower with a distributor, wherein openings are formed on the two side surfaces and the bottom surface of a feed pipe entering into the body of the desorption tower, the percentage of opening is 20 to 50 percent of the total area of the two side surfaces and the bottom surface of the feed pipe, and the discharge opening of the feed pipe entering into the body of the desorption tower is sealed; or a liquid distributor is arranged at the discharge opening of the feed pipe entering into the desorption tower, and the upper surface of the basal body of the liquid distributor is round, sector-shaped or elliptical. The desorption tower with the distributor, which is provided by the utility model, is used for desorbing and separating hydrogen chloride component in liquid-enriched materials, the desorbing and separating efficiency is greatly improved, and energy is saved.
Description
One, technical field:
The utility model relates to a kind of desorber, particularly relates to a kind of desorber that has distributor.
Two, background technology:
In production of polysilicon technology, will produce a large amount of rich solution materials, contain silicon tetrachloride (SiCl in the rich solution material
4), trichlorosilane (SiHCl
3), dichloro-dihydro silicon (SiH
2C1
2) and hydrogen chloride (HCl) gas, if its rich solution material is not separated purification, wherein expensive trichlorosilane (trichlorosilane is the raw material of preparation polysilicon product) will cause waste, and contaminated environment, is unfavorable for environmental protection.
In order effectively to separate the rich solution material; Trichlorosilane is wherein separated, utilized again, at first will be stored in rich solution product pump in the rich solution holding vessel and deliver to and carry out desorb in the desorber as the raw material of preparation polysilicon product; Remove hydrogen chloride composition and dichloro-dihydro silicon composition in the material; Then mixed material behind hydrogen chloride and the dichloro-dihydro silicon is isolated in desorb and be pumped to rectifying column and carry out rectifying separation, isolate trichlorosilane, utilize again as the raw material of producing polysilicon.
At present, when adopting desorber that its rich solution material is carried out desorb, desorb tower body top is provided with a feed pipe; Material gets in the desorber through feed pipe, is down moved by the desorber top from the discharging opening of feed pipe, and the rich solution material gets in the desorber from the desorber middle part; The rich solution material becomes steam up through heat in desorber; With from the descending material of feed pipe discharging opening through contacting, utilize the different physical property of boiling point, the hydrogen chloride component separating is come out; Discharge from the desorber top, desorb is isolated mixed material behind the hydrogen chloride composition and is delivered to rectifying column and carry out rectifying separation.Because the material that feeds is by feed pipe discharging opening ejection in the desorber; Its spray effect is not good enough; Can not make the material of sprinkling undertaken fully, contact uniformly by the rich solution material steam of heat with the entering tower body is interior; Cause hydrogen chloride component separating effect bad, need be through repeatedly desorb separation, its hydrogen chloride composition also is difficult to thoroughly separate.Thereby, adopt this equipment desorb to separate the hydrogen chloride composition in the rich solution material, desorption efficiency is low, wastes energy.
Three, the utility model content:
The utility model separates the defective that the rich solution material exists in order to overcome present desorber desorb; A kind of desorber that has distributor is provided; The desorber desorb of adopting the utility model to have distributor separates the rich solution material, and effectively desorb separates the hydrogen chloride composition in the rich solution material, reduces the number of times of desorb repeatedly; Improve desorption efficiency, the energy savings source.
In order to address the above problem, the technical scheme that the utility model adopts is:
The utility model provides a kind of desorber that has distributor, comprises desorber and feed pipe, is evenly equipped with perforate in the feed pipe two sides and the bottom surface that get into desorb tower body inside, gets into the discharging opening place sealing of the inner feed pipe of desorb tower body; Perhaps the feed pipe discharging opening is provided with a liquid distribution trough in getting into the desorb tower body.
According to the above-mentioned desorber that has distributor, said feed pipe two sides and bottom surface are evenly equipped with perforate, and percent opening is 20～50% of feed pipe two sides and a base area summation.
According to the above-mentioned desorber that has distributor, the rounded shape of the body upper surface of said liquid distribution trough or covering of the fan shape or elliptical shape.
According to the above-mentioned desorber that has distributor, the percent opening on the said liquid distribution trough accounts for 20～80% of liquid distribution trough body upper surface area.
According to the above-mentioned desorber that has distributor, said feed pipe is arranged at desorb tower body top.
The positive beneficial effect of the utility model:
1, the two sides and the bottom surface of the utility model feed pipe in getting into the desorb tower body are evenly equipped with perforate; And seal the discharging opening of feed pipe; The material that gets in the desorber can be evenly through the perforate that is provided with and large-area down sprinkling; Can make get in the desorber by the rich solution material steam of heat with spray descending material from feed pipe and carry out fully, contact uniformly, process is abundant, uniform to be contacted, and utilizes the different physical property of boiling point; Can effectively isolate the hydrogen chloride composition in the rich solution material, the hydrogen chloride composition of separating is discharged from desorber top.The desorber desorb that has distributor through the utility model separates the hydrogen chloride composition in the rich solution material, and its desorb separative efficiency can improve greatly, and can energy savings.
2, the discharging opening place of the utility model feed pipe in getting into the desorb tower body is provided with a liquid distribution trough; Get into the material even and large-area down sprinkling in the desorber through the liquid distribution trough that is provided with; Can make get in the desorber by the rich solution material steam of heat with carry out fully, contact uniformly from the descending material of feed pipe sprinkling; Through abundant, contact uniformly; Utilize the different physical property of boiling point, can effectively isolate the hydrogen chloride composition in the rich solution material, the hydrogen chloride composition of separating is discharged from desorber top.The desorber desorb that has distributor through the utility model separates the hydrogen chloride composition in the rich solution material, and its desorb separative efficiency can improve greatly, and can energy savings.
