Abstract
The utility model discloses rectifying device for processing hard separated materials. The utility model is composed of two-five rectifying towers which are connected in series, wherein, the rectifying towers are composed of a plurality of tower sections which is filled with fillers; automatic liquid level controllers are arranged among the rectifying towers, and condensed fluid receivers and condensed liquid distributors are arranged among the tower sections of the rectifying towers; the branch pipes of the condensed fluid distributors and the inner surface of the lower part of a main pipe are position on the same horizontal plane; small holes are arranged outside the center holes of the condensate receivers to solve the detention of a liquid dead angle. In addition, the utility model is provided with an automatic liquid discharge device for a tower kettle, and the automatic liquid discharge device for a tower kettle is composed of double U-shaped pipes and a balance pipe. Through the use of the utility model, that the separated materials purity of the hard separated materials is higher than 99 % is guaranteed.
Description
The utility model relates to a kind of fractionating device, particularly relates to the difficult separation mixture rectifier unit of a kind of processing.
Existing difficult separation mixture adopts the rectifier unit of single tower usually, in order to guarantee to separate the purity of back material, often needs to improve the height of rectifying column.Like this, not only caused the inconvenience of installation, manufacturing and production operation, and, also can influence the uniformity that gas-liquid contacts, cause the decrease in efficiency of tower.For this reason, also have the people with repeatedly repeatedly rectifying solve this problem, but produce that cost improves or problems such as intermittent operation, cause the device Fraquent start, efficient reduces.
The purpose of this utility model is to provide a kind of back feed purity that can guarantee to separate, the difficult separation mixture rectifier unit of processing easy and simple to handle, low-cost continuous operation.
Further purpose of the present utility model is to provide a kind of condensed fluid of eliminating to be detained the dead angle, to improve the difficult separation mixture rectifier unit of the processing that separates the back feed purity.
Task of the present utility model is achieved in that 2～5 rectifying columns being made up of some tower joints that filler is housed are connected into one and handle difficult separation mixture rectifier unit.Be provided with liquid level automatic control device between the rectifying column of series connection, be provided with condensate liquid recipient and distributor between the tower joint of rectifying column, distributor is made up of arm and house steward, and arm and house steward's lower inner surface is in same horizontal plane.The material that enters first rectifying column is after the exchange of filler gas-liquid, and liquid is collected by the condensate liquid recipient and flowed into distributor, and is evenly distributed on the filler, through the several of several towers joints repeatedly after, flow out via liquid level automatic control device.And gas evaporation current to the second rectifying column that makes progress, and repeat the separation process of first rectifying column, and the liquid of condensation is sent first rectifying column back to through liquid level automatic control device, and gas is then discharged by cat head, realizes the separation of material.
The utility model is in series 2～5 rectifying columns owing to adopted liquid level automatic control device, can realize the continuous rectification to difficult separation mixture, simplifies the operation, and reduces cost;
The arm of distributor and house steward's lower inner surface are in same horizontal plane, can avoid producing the liquid dead angle, improve the purity of separating the back material;
The central gas phase channel outside of condensate liquid recipient is provided with 1-20 aperture, and the liquid in the recipient was kept certain height, and the dead angle that can solve liquid again is detained, and makes the strength of fluid unanimity in the recipient, guarantees that the purity of separating the back material is higher than 99%;
Adopt the tower still automatic draining device of forming by dual U-shaped pipe and balance pipe, both simplified leveling device, can keep the constant of tower bottoms face again.
Below, introduce the utility model in conjunction with the accompanying drawings in detail.

Embodiment one
Be connected into one by some tower joint 10 2～5 rectifying columns forming that filler 9 is housed and handle difficult separation mixture rectifier unit.As shown in Figure 4, be provided with liquid level automatic control device 7 between the rectifying column of 3 series connection, be provided with condensate liquid recipient 2 and distributor 1 between the tower joint 10 of rectifying column, distributor 1 is made up of arm 13 and house steward 14, and arm 13 is in same horizontal plane with house steward 14 lower inner surface.Component is 15% 2-methyl butanol and 85% isomer 3-methyl butanol, enter first rectifying column distributor, after the exchange of filler gas-liquid, liquid is collected by condensate liquid recipient 2 and is flowed into distributor 1, and be evenly distributed on the filler 9, through the several of several towers joint repeatedly after, flow out via liquid level automatic control device 7, obtain the 3-methyl butanol of 99% above purity.Evaporation current to the second and the 3rd rectifying column and gas makes progress, and repeat the separation process of first rectifying column, the liquid of condensation is sent first and second rectifying column back to through liquid level automatic control device 7, and gas is then discharged by cat head, after the condensation the 2-methyl butanol of 99% above purity.
Embodiment two is connected into one by some tower joint 10 2 rectifying columns forming that high efficiency packing 9 is housed and handles difficult separation mixture rectifier unit.Be provided with by float controller valve 8 and liquid between the rectifying column of series connection and return the liquid level automatic control device 7 that pump 6 is formed, be provided with condensate liquid recipient 2 and distributor 1 between the tower joint 10 of rectifying column.Condensate liquid recipient 2 central authorities are provided with a gas phase channel 11, and it is 1～10 millimeter 1-20 aperture 12 that the outside of gas phase channel 11 is provided with diameter.Distributor 1 is made up of arm 13 and house steward 4, and arm 13 is in same horizontal plane with house steward 14 lower inner surface.Component is 15% 2-methyl butanol and 85% isomer 3-methyl butanol, enters first rectifying column distributor, and after the exchange of high efficiency packing 9 gas-liquids, liquid is collected by condensate liquid recipient 2 and flowed into distributors 1, and is evenly distributed on the high efficiency packing 10.Aperture 12 on the condensate liquid recipient 2 can guarantee that liquid does not have the dead angle and is detained, and makes the concentration unanimity of liquid in the recipient 2.Through the several of several towers joint 10 repeatedly after, it is that 3-methyl butanol more than 99% is discharged automatically above the purity of liquid level that liquid flows into the tower still automatic draining device 4. is made up of dual U-shaped pipe 5 and balance pipe 3.U type liquid sealing pipe 15 can prevent that the gas in the balance pipe from flowing backwards.Meanwhile, gas evaporation current to the second rectifying column that makes progress, and repeat the separation process of first rectifying column, the liquid of condensation is sent first rectifying column back to through liquid level automatic control device 7, gas is then discharged by cat head, gets the 2-methyl butanol of 99% above purity after the condensation.
