Abstract
The utility model discloses a kind of tetrachloroethane vaporization raffinate secondary separation recovery system, it comprises tetrachloroethane gas-liquid separator and connected reboiler, cartridge filter is connected by pipeline bottom described reboiler, pipeline is provided with valve, filter cartridge outlet is connected with withdrawing can inlet pipeline, withdrawing can outlet is returned by pipeline and is connected with gas-liquid separator, and withdrawing can entrance end is connected with compression gas tank.Compared with prior art, the tetrachloroethane vaporization raffinate secondary separation retrieving arrangement that the utility model provides, when reboiler does not stop, the raffinate in reboiler can be carried out filtering separation and recycle tetrachloroethane, reduce the consumption of product, improve production efficiency, extend the life cycle of reboiler simultaneously.
Description
Technical field
The utility model relates to a kind of tetrachloroethane vaporization raffinate secondary separation recovery system, belongs to trieline production field.
Background technology
In trieline production process, the liquid tetrachloroethane after the rectifying of tetrachloroethane tower is sent in gas-liquid separator, carries out intensification vaporization deliver to reactor and carry out scission reaction and obtain the thick product of trieline through the reboiler that is connected with gas-liquid separator.In actual production process, the situation that reboiler there will be local superheating causes tetrachloroethane to occur " analysing carbon " phenomenon, and a carbon dust part for precipitation is deposited in reboiler lower cover, and a part is deposited on the tubulation inwall of reboiler; Along with the prolongation of duration of service, the carbon dust that tubulation inwall deposits can be cumulative, causes reboiler heat transfer coefficient significantly to decline, and life cycle shortens; This just causes needing regularly to extend reboiler life cycle by the raffinate more from reboiler bottom discharge carbonaceous powder with short-term, and finally only has the raffinate in parking disposal facilities and clean the deposition carbon dust on reboiler tubulation inwall.
Utility model content
The purpose of this utility model is just for above-mentioned the deficiencies in the prior art, a kind of tetrachloroethane vaporization raffinate secondary separation recovery system is provided, carbon dust in raffinate and thick tetrachloroethane can be carried out physical sepn by it under reboiler does not need the situation of stopping, recovered material, extends reboiler life cycle.
To achieve these goals, the technical solution adopted in the utility model is such:
A kind of tetrachloroethane vaporization raffinate secondary separation recovery system, comprise tetrachloroethane gas-liquid separator and connected reboiler, it is characterized in that: bottom described reboiler, connect cartridge filter by pipeline, pipeline is provided with valve, filter cartridge outlet is connected with withdrawing can inlet pipeline, withdrawing can outlet is returned by pipeline and is connected with gas-liquid separator, and withdrawing can entrance end is connected with compression gas tank.
Preferably, be connected with and take out negative pressure device bottom above-mentioned reboiler, it can make the carbon dust on reboiler tubulation inwall be sucked in the raffinate fallen to bottom reboiler, reduces the deposition of carbon dust on tubulation inwall, improves the life cycle of reboiler.
Preferably, above-mentioned cartridge filter is provided with and takes out negative pressure device, it can accelerate the filtration velocity of cartridge filter, enhances productivity.
The above is taken out negative pressure device and is suitable for vacuum pump known in those skilled in the art, water-ring vacuum pump etc. and takes out negative pressure device.
Preferably, above-mentioned compression gas tank is nitrogen pot, and safety non-toxic is economic and practical.
During use, according to the raffinate situation bottom reboiler, Open valve, the raffinate bottom reboiler is drained into cartridge filter, and the tetrachloroethane filtering out carbon dust through filter cylinder enters into withdrawing can, open the pressurized gas on withdrawing can, the thick tetrachloroethane collected in withdrawing can is just pressed into and turns back in gas-liquid separator, realizes the recycling of tetrachloroethane vaporization raffinate, has both reduced the consumption of product, clear up again the carbon dust in reboiler, extend the life cycle of reboiler.
Compared with prior art, the tetrachloroethane vaporization raffinate secondary separation retrieving arrangement that the utility model provides, when reboiler does not stop, the raffinate in reboiler can be carried out filtering separation and recycle tetrachloroethane, reduce the consumption of product, improve production efficiency, extend the life cycle of reboiler simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Marginal data:
1, tetrachloroethane gas-liquid separator; 2, reboiler; 3, cartridge filter; 4, withdrawing can; 5,8: vacuum pump; 6, nitrogen pot; 7, valve.
Embodiment
In order to clearly understand the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in the examples below.
See Fig. 1, a kind of tetrachloroethane vaporization of the utility model raffinate secondary separation recovery system, comprise tetrachloroethane gas-liquid separator 1 and connected reboiler 2, cartridge filter 3 is connected by pipeline bottom reboiler 2, pipeline is provided with valve 7, cartridge filter 3 outlet is connected with withdrawing can 4 inlet pipeline, and withdrawing can 4 is exported to be returned by pipeline and is connected with gas-liquid separator 1, and withdrawing can 4 entrance end is connected with nitrogen pot 6; Be connected with vacuum pump 8 bottom described reboiler 2, it can make the carbon dust on reboiler tubulation inwall be sucked in the raffinate fallen to bottom reboiler, reduces the deposition of carbon dust on tubulation inwall, improves the life cycle of reboiler; Described cartridge filter 3 is provided with vacuum pump 5, and it can accelerate the filtration velocity of cartridge filter, enhances productivity.
In trieline production process, the liquid tetrachloroethane after the rectifying of tetrachloroethane tower is sent in gas-liquid separator 1, carries out intensification vaporization deliver to reactor and carry out scission reaction and obtain the thick product of trieline through the reboiler 2 that is connected with gas-liquid separator 1.According to the raffinate situation bottom reboiler 2, Open valve 7, raffinate bottom reboiler 2 is drained into cartridge filter 3, be-0.005 ~-0.08MPa at vacuum pump 5(relative vacuum degree) effect under the filtration velocity of cartridge filter 3 faster, the tetrachloroethane filtering out carbon dust through filter cylinder 3 enters into withdrawing can 4, open the pressurized gas on withdrawing can 4, the thick tetrachloroethane collected in withdrawing can is just turned back to (nitrogen pressure controls at 0.1 ~ 0.2MPa) in gas-liquid separator 1 by the nitrogen press-in in nitrogen pot 6, realize the recycling of tetrachloroethane vaporization raffinate, both the consumption of product had been reduced, clear up again the carbon dust in reboiler, extend the life cycle of reboiler.
